  The present invention relates to a condenser and a condensing system including the same.

  For example, Patent Document 1 discloses that water generated in a chemical heating device for a vehicle that repeatedly generates heat (reaction heat) using a reversible reaction between an alkaline earth metal oxide (for example, calcium oxide) and water. A condenser that cools and condenses water vapor generated when an oxide is decomposed into an oxide and water is disclosed.

JP-A-7-180539

  In this type of condenser, when the condensed water condensed flows through the flow path, flow path resistance acts on the condensate. If the condensed water becomes difficult to flow through the flow path due to the flow path resistance and the condensed water stays in the flow path, the cooling area (heat exchange area) of the water vapor is reduced, and the cooling efficiency is lowered. In particular, in a condenser that condenses low-pressure water vapor, the influence of flow path resistance becomes large, and thus cooling efficiency may be greatly reduced.

  In view of the above facts, an object of the present invention is to provide a condenser that can suppress a decrease in cooling efficiency, and a condensing system including the condenser.

The condenser according to claim 1, wherein the condenser extends in the vertical direction and receives a vapor from an upper end thereof, and a first refrigerant flow path through which a refrigerant for cooling the vapor in the first vapor flow path flows. a first cooling unit for chromatic bets, said with first provided on the downstream side of the cooling unit is connected hermetically to the lower side of the first cooling section, the upper end portion extends vertically from the first cooling section second cooling unit for chromatic and second steam flow path steam is introduced, and a second refrigerant flow path through which the refrigerant flows to cool at a temperature lower than the vapor of the first cooling portion of the second steam passage If, formed between the first cooling unit and the second cooling unit, and a common steam chamber which is defined by the side wall surface of the housing for accommodating the first cooling unit and the second cooling unit, the The first refrigerant channel and the second refrigerant channel are corrugated fins with the horizontal direction as the longitudinal direction. The first steam channel and the second steam channel are formed of corrugated fins whose longitudinal direction is the longitudinal direction, and the first cooling part and the second cooling part are interposed through the common steam chamber. The first vapor channel and the first refrigerant channel are alternately stacked in the horizontal direction, and the second vapor channel and the second refrigerant channel are alternately stacked in the horizontal direction. The temperature of the refrigerant flowing through the second refrigerant flow path is lower than the temperature of the refrigerant flowing through the first refrigerant flow path.

  According to the condenser of the first aspect, the first cooling unit and the second cooling unit are provided. The second cooling unit is provided on the downstream side of the first cooling unit and is airtightly connected to the first cooling unit. The steam that has flowed into the first cooling unit is cooled by the first cooling unit, and then flows into the second cooling unit and is cooled by the second cooling unit. As a result, when the steam is cooled to a predetermined temperature or lower, the steam is condensed into a condensate.

  Here, the second cooling unit cools the steam flowing in from the first cooling unit at a temperature lower than that of the first cooling unit. Thereby, the vapor pressure in the second cooling unit is lower than the vapor pressure in the first cooling unit. Due to the pressure difference between the first cooling part and the second cooling part, the condensate (hereinafter sometimes referred to as “steam”) in which the steam in the first cooling part or the steam in the first cooling part is condensed is second cooled. It becomes easy to flow to the part.

In this way, by making the vapor pressure in the second cooling unit lower than the vapor pressure in the first cooling unit and making the vapor in the first cooling unit flow easily to the second cooling unit, the vapor in the first cooling unit, etc. Residence is suppressed. Therefore, since the reduction in the cooling area of the first cooling unit is reduced, the reduction in cooling efficiency is suppressed.
According to the condenser of claim 1, the first steam is generated by providing an interval (common steam chamber) between the lower end of the first steam channel and the upper end of the second steam channel. Direct heat exchange between the flow path and the second steam flow path is suppressed. As a result, the temperature difference between the steam in the first steam channel and the steam in the second steam channel becomes large, so the pressure difference between the steam pressure in the first cooling unit and the steam pressure in the second cooling unit is large. Become. This pressure difference makes it easier for the condensate in the first steam channel to flow to the second steam channel. Accordingly, the retention of steam or the like in the first steam channel is suppressed, so that a decrease in cooling efficiency is suppressed.

According to the condenser of claim 1, and a first steam flow path first cooling portion extends vertically. The steam that flows in from the upper end of the first steam channel flows downward along the first steam channel while being cooled by the first cooling unit. And when a vapor | steam is cooled below to predetermined temperature, it will condense and will become a condensate. This condensate flows downward along the first vapor channel. That is, the condensate condensed in the first steam channel flows down in the direction of gravity along the first steam channel.

  Here, when the flow path through which the condensate flows is a narrow flow path, the condensate flowing through the flow path grows from the liquid film to the liquid plug in which the liquid droplets are collected by surface tension. As the condensate grows, the flow path resistance against the flow of the condensate increases and the condensate hardly flows in the flow path.

On the other hand, in the present invention, the condensate condensed in the first steam channel flows down in the direction of gravity along the first steam channel, so that the influence of the channel resistance of the first steam channel is reduced. The condensate easily flows through the first steam flow path. Accordingly, the retention of steam or the like in the first steam channel is suppressed, so that a decrease in cooling efficiency is suppressed.

According to the condenser of claim 1, flow and first cooling section and a second cooling section by arranged in the vertical direction, the condensate condensed in the first steam flow path is, as in the direction of gravity Into the second cooling section. As a result, the condensate in the first steam flow path can easily flow to the second cooling unit.

  Furthermore, the condensate that has flowed into the second cooling section flows into the upper end portion of the second steam channel that extends in the vertical direction, and flows downward along the second steam channel. That is, the condensate that has flowed into the second steam channel flows down in the direction of gravity along the second steam channel. As a result, the condensate that has flowed into the second steam channel becomes easy to flow along the second steam channel.

  As described above, in the present invention, since the condensate stays in the first steam channel and the second steam channel is suppressed, a decrease in the cooling efficiency of the first cooling unit and the second cooling unit is suppressed.

According to the condenser of claim 1, the vapor of the first steam flow path is cooled by the refrigerant flowing through the first refrigerant flow path. On the other hand, the vapor in the second vapor channel is cooled by the refrigerant flowing through the second refrigerant channel. The temperature of the refrigerant flowing through the second refrigerant flow path is set lower than the temperature of the refrigerant flowing through the first refrigerant flow path.

  As a result, the temperature of the steam in the second steam channel is lower than the temperature of the steam in the first steam channel, so that the vapor pressure in the second steam channel is lower than the steam pressure in the first steam channel. Also lower. Due to the pressure difference between the vapor pressure in the second vapor channel and the vapor pressure in the first vapor channel, the condensate in the first vapor channel can easily flow into the second vapor channel. Accordingly, the retention of steam or the like in the first steam channel is suppressed, so that a decrease in cooling efficiency is suppressed.

Condenser according to claim 2, in the condenser according to claim 1, wherein the first coolant channel is coupled to the downstream side of the second refrigerant flow.

According to the condenser of claim 2, by a concatenation of first refrigerant flow path on the downstream side of the second refrigerant flow path, a second refrigerant flow which is heated by heat exchange with the second steam passage The refrigerant in the path flows to the first refrigerant flow path. That is, the temperature of the refrigerant flowing through the second refrigerant flow path is lower than the temperature of the refrigerant flowing through the first refrigerant flow path. As a result, the vapor pressure in the second steam channel becomes lower than the vapor pressure in the first steam channel, so that the condensate in the first steam channel easily flows into the second steam channel. Accordingly, the retention of steam or the like in the first steam channel is suppressed, so that a decrease in cooling efficiency is suppressed.

  Further, the first refrigerant flow path and the second refrigerant flow path are connected, and the refrigerant flowing through the second refrigerant flow path is caused to flow to the first refrigerant flow path, whereby the first refrigerant flow path and the second refrigerant flow path are provided. Compared with a configuration in which separate refrigerants are passed, the device structure can be simplified.

The condensation system according to claim 3 is provided on the downstream side of the condenser according to claim 1 or claim 2 and the second cooling part of the condenser, and the condensation in which the vapor in the second cooling part is condensed. A storage unit that stores the liquid; and a flow unit that causes the condensate in the second cooling unit to flow to the storage unit.

According to the condensing system of the third aspect , the second steam is caused to flow by flowing means the condensate in the second steam channel to the storage section provided on the downstream side of the second steam channel. The residence of steam or the like in the flow path is suppressed. Accordingly, since the decrease in the cooling area of the second steam channel is reduced, the decrease in the cooling efficiency of the second cooling unit is suppressed.

  As described above, according to the condenser according to the present invention and the condensing system including the same, it is possible to suppress a decrease in cooling efficiency.

It is a perspective view which notches and shows the principal part of the condenser which concerns on one Embodiment of this invention partially. It is a front view which shows the 1st steam flow path which concerns on one Embodiment of this invention. It is a schematic diagram which shows schematic system structure of the condensation system which concerns on the modification of this invention.

  Hereinafter, a condenser according to an embodiment of the present invention and a condensing system including the same will be described with reference to the drawings. In each figure, an arrow J appropriately shown indicates the flow direction of the steam and the condensate, and an arrow C indicates the flow direction of the refrigerant. An arrow Z indicates the vertical direction (gravity direction).

  First, the overall configuration of the condensation system according to the present embodiment will be described.

  FIG. 1 schematically shows a schematic system configuration of a condensation system 10 according to an embodiment. This condensing system 10 is airtightly connected to, for example, a rapid heating chemical heating device (chemical heat storage device) mounted on a vehicle or the like, and the steam generated by the chemical heating device is cooled and condensed (liquefied). The condensate is returned to the chemical heating device.

  The condensation system 10 includes a condenser 12, a tank 60 as a storage unit, and a pump 64 as a flow means. The condenser 12 includes a housing 14, a first heat exchanger 20 as a first cooling unit, and a second heat exchanger 40 as a second cooling unit.

  The housing 14 is hermetically connected to a chemical heating device (not shown) via a steam supply line 16, and a low pressure (for example, 30 kPa or less) generated by the chemical heating device from a steam inlet 14 </ b> I formed at the upper end of the housing 14. Steam (for example, water vapor or alternative chlorofluorocarbon steam) is introduced.

  Below the condenser 12, a tank 60 for storing condensate is provided. The tank 60 and the housing 14 of the condenser 12 are airtightly connected via a condensate circulation line 18. Thereby, the condensate condensed in the first heat exchanger 20 and the second heat exchanger 40 in the housing 14 passes through the condensate circulation line 18 from the condensate outlet 14E formed in the lower end portion of the housing 14. It flows into the tank 60. The condensate circulation line 18 is provided with a pump 64 that pumps the condensate in the housing 14 to the tank 60.

  The tank 60 is hermetically connected to a chemical heating device (not shown) via a condensate discharge line 62 so that the condensate temporarily stored in the tank 60 returns to the chemical heating device. The upper part of the tank 60 and the upper part of the housing 14 of the condenser 12 are connected by an internal pressure adjustment line 66 that communicates the inside of the tank 60 and the inside of the housing 14. Thereby, when the condensate in the housing 14 is pumped to the tank 60 by the pump 64, the pressure increase in the tank 60 is suppressed. The tank 60 and the pump 64 can be omitted as appropriate.

  Next, the configuration of the condenser according to this embodiment will be described.

  As shown in FIG. 2, in the housing 14 of the condenser 12, the first heat exchanger 20 is accommodated in the upper portion thereof, and the second heat exchanger 40 is accommodated in the lower portion thereof. The first heat exchanger 20 includes a plurality of first steam fins 24 and a plurality of first refrigerant fins 28.

  The first steam fins 24 are made of metal corrugated fins, and the first steam flow paths 22 are formed between adjacent fins. Similarly, the first refrigerant fin 28 is formed of a metal corrugated fin, and the first refrigerant flow path 26 is formed between adjacent fins. The first steam fins 24 and the first refrigerant fins 28 are horizontally oriented so that the first steam flow paths 22 and the first refrigerant flow paths 26 intersect (substantially orthogonal in the present embodiment). Are joined alternately so that heat exchange is possible by welding or the like. Although not shown, a metal partition plate that partitions the first vapor channel 22 and the first refrigerant channel 26 is disposed between the first vapor fin 24 and the first refrigerant fin 28. Has been.

  The first steam fins 24 are arranged with the longitudinal direction of the first steam channel 22 in the vertical direction. The first steam passage 22 has a steam inlet 22I formed at the upper end and a steam outlet 22E formed at the lower end, and is introduced from the steam inlet 14I of the housing 14 (see FIG. 1). The steam is introduced from the steam inlet 22I of the first steam flow path 22.

  On the other hand, the first refrigerant fin 28 is arranged with the longitudinal direction of the first refrigerant flow path 26 in the horizontal direction. Upstream end portions of these first refrigerant flow paths 26 are second refrigerant flow paths which will be described later via a U-shaped refrigerant circulation line 54 (see FIG. 1) constituted by a header portion (not shown), pipes, and the like. 46 is connected. Thereby, the refrigerant that has flowed through the second refrigerant flow path 46 flows into each first refrigerant flow path 26. When this refrigerant flows through the first refrigerant flow path 26, the first refrigerant fin 28 and the first vapor fin 24 are cooled, and the vapor in the first vapor flow path 22 is cooled. Yes. Moreover, the refrigerant | coolant discharge line 56 (refer FIG. 1) which discharges | emits a refrigerant | coolant is connected to the downstream edge part of each 1st refrigerant flow path 26 via the header part which is not shown in figure.

  A second heat exchanger 40 is disposed below (downstream side) the first heat exchanger 20. The second heat exchanger 40 has the same configuration as the first heat exchanger 20 and includes a plurality of second steam fins 44 and a plurality of second refrigerant fins 48. The second steam fins 44 are made of metal corrugated fins, and a second steam flow path 42 is formed between adjacent fins. Similarly, the second steam fins 44 are made of metal corrugated fins, and a second refrigerant channel 46 is formed between adjacent fins. The second steam fins 44 and the second refrigerant fins 48 are arranged in the horizontal direction so that the second steam flow paths 42 and the second refrigerant flow paths 46 intersect (substantially orthogonal in the present embodiment). Are joined alternately so that heat exchange is possible by welding or the like. Although not shown, a metal partition plate that partitions the second vapor channel 42 and the second refrigerant channel 46 is disposed between the second vapor fin 44 and the second refrigerant fin 48. Has been.

  Here, the second heat exchanger 40 is disposed at a position spaced downward (downstream) from the first heat exchanger 20, and between the first heat exchanger 20 and the second heat exchanger 40. Is formed with a common steam chamber 50 defined by the side wall 14W of the housing 14. The first heat exchanger 20 and the second heat exchanger 40 are hermetically sealed with a space H between the first steam channel 22 and the second steam channel 42 via the common steam chamber 50. It is connected. As a result, the steam in the first steam flow path 22 and the condensate condensed in the first steam flow path 22 (hereinafter sometimes referred to as “steam etc.”) pass through the common steam chamber 50 to the second steam. It flows into the steam inlet 42I of the flow path 42. Further, heat exchange is not directly performed between the first steam fin 24 and the second steam fin 44.

  The steam or the like flowing into the second steam channel 42 flows along the second steam channel 42 and is discharged from the steam outlet 42E to the condensate circulation line 18 through the condensate outlet 14E of the housing 14. It has become.

  On the other hand, the second refrigerant fins 48 are arranged with the longitudinal direction of the second refrigerant flow path 46 in the horizontal direction. A refrigerant supply line 52 (see FIG. 1) into which a refrigerant made of gas or liquid flows is connected to an upstream end portion of each second refrigerant flow path 46 via a header portion (not shown). As the refrigerant flows through the second refrigerant flow path 46, the second refrigerant fin 48 and the second vapor fin 44 are cooled, and the vapor in the second vapor flow path 42 is cooled. Yes. In addition, a refrigerant circulation line 54 is connected to a downstream end portion of each second refrigerant flow path 46 via a header portion (not shown), and the refrigerant flowing through each second refrigerant flow path 46 has a first heat. It flows to the first refrigerant flow path 26 of the exchanger 20.

  Next, the operation of this embodiment will be described.

As shown in FIG. 1, steam generated by a chemical heating device (not shown) is supplied to the condenser 12 via a steam supply line 16. This vapor is introduced through a steam inlet port 14 A formed on the upper portion of the housing 14 of the condenser 12 to the first heat exchanger 20, it is flowed from the steam inlet 22I to the first steam flow path 22. Then, the steam that has flowed into the first steam flow path 22 flows downward along the first steam flow path 22 while radiating heat. That is, the steam that has flowed into the first steam channel 22 exchanges heat (dissipates heat) with the first steam fins 24 cooled by the refrigerant flowing through the first refrigerant channel 26, and thus the first steam channel. Flows downward along the line 22. As a result, when the steam flowing through the first steam flow path 22 is cooled to a predetermined temperature or lower, it is condensed and becomes a condensate.

  The steam or the like that flows downward along the first steam flow path 22 flows into the second heat exchanger 40 through the common steam chamber 50. The steam that has flowed into the second heat exchanger 40 flows into the second steam flow path 42 from the steam inlet 42I, and flows downward along the second steam flow path 42 while radiating heat. That is, the steam that has flowed into the second steam channel 42 exchanges heat (dissipates heat) with the second steam fins 44 cooled by the refrigerant flowing through the second refrigerant channel 46, and thus the second steam channel. Flows downward along 42. As a result, when the steam flowing in the second steam flow path 42 is cooled to a predetermined temperature or lower, it is condensed and becomes a condensate.

  Thus, the condensate condensed in the first heat exchanger 20 and the second heat exchanger 40 of the condenser 12 passes through the condensate circulation line 18 from the condensate outlet 14E formed at the lower end of the housing 14. It is discharged to the tank 60. At this time, the condensate in the housing 14 is pumped to the tank 60 by a pump 64 provided in the condensate circulation line 18. The condensate pumped to the tank 60 is temporarily stored in the tank 60 and then circulated through a condensate circulation line 36 to a chemical heating device (not shown).

Here, the channel resistance of the first steam channel 22 acts on the condensate flowing through the first steam channel 22. When the condensed water becomes difficult to flow through the first steam channel 22 due to this channel resistance, the condensed water stays in the first steam channel 22, the cooling area (heat radiation area) of the steam decreases, and the cooling efficiency decreases. . In particular, if the number of fins is increased by narrowing the interval between the fins of the first steam fins 24 in order to secure the cooling area (heat radiation area) of the steam, the cross-sectional area of the first steam flow path 22 is reduced. The first steam channel 22 becomes a narrow channel. In this case, as shown in the schematic diagram of FIG. 3, the condensate condensed in the first vapor flow path 22 grows from the liquid film to the liquid plug 70 in which the liquid droplets are collected by the surface tension. . As the condensate grows, the flow resistance against the flow of the condensate increases, and the liquid plug 70 hardly flows in the first vapor flow path 22. In FIG. 3, and replacing the first steam flow path 22 to the flow passage of the cylindrical diameter (typical diameter) d _e.

  As a countermeasure, in the condenser 12 according to the present embodiment, the first steam channel 22 extends in the vertical direction, and the liquid plug 70 in the first steam channel 22 flows down in the direction of gravity. By flowing the liquid plug 70 in the first vapor channel 22 in the direction of gravity in this way, the liquid plug 70 can easily flow in the first vapor channel 22 by its own weight G.

Further, the first refrigerant flow path 26 of the first heat exchanger 20 and the second refrigerant flow path 46 of the second heat exchanger 40 are connected by the refrigerant circulation line 54, and flowed through the second refrigerant flow path 46. The refrigerant flows through the first refrigerant flow path 26. That is, the refrigerant in the second refrigerant flow path 46 that has been heated by heat exchange with the second vapor fins 44 flows to the first refrigerant flow path 26. Thereby, the steam flowing through the first steam channel 22 is cooled at a higher temperature than the steam flowing through the second steam channel 42. In other words, the steam flowing through the second steam channel 42 is cooled at a lower temperature than the steam flowing through the first steam channel 22. As a result, the temperature of the steam in the second steam channel 42 is lower than the temperature of the steam in the first steam channel 22, so that the liquid plug is compared with the steam pressure P ₁ upstream of the liquid plug 70. 70 the vapor pressure _{P 2} on the downstream side is lowered in. Due to the pressure loss R due to the pressure difference between the vapor pressure P ₁ and the vapor pressure P ₂ , the liquid plug 70 easily flows in the first vapor flow path 22.

Therefore, for example, by adjusting the dead weight G of the liquid plug 70 and the pressure loss R so as to satisfy the following formula (1), the flow resistance in the first steam flow path 22 (friction resistance F) is caused. The retention of the liquid plug 70 is suppressed. Thereby, since the reduction | decrease of the cooling area of the vapor | steam in the 1st vapor flow path 22 is suppressed, the fall of cooling efficiency is suppressed. In particular, this embodiment is effective for a condenser that condenses low-pressure steam (for example, 30 kPa or less, particularly 10 kPa or less).
G + R> F (1)

Further, by providing a space H between the lower end of the first steam channel 22 and the upper end of the second steam channel 42, the gap between the first steam channel 22 and the second steam channel 42 is increased. Direct heat exchange is suppressed. As a result, the temperature difference between the steam in the first steam channel 22 and the steam in the second steam channel 42 is increased, so that the pressure difference between the steam pressure P ₁ and the steam pressure P ₂ can be increased. . Accordingly, the pressure loss R in the above formula (1) becomes large, so that the liquid plug 70 becomes easier to flow in the first steam flow path 22.

  In addition, by disposing the second heat exchanger 40 below the first heat exchanger 20, the condensate condensed in the first steam channel 22 flows in the direction of gravity as it is, and the second steam channel 42. Is flowed into. Thereby, the condensate in the first steam flow path 22 easily flows to the second heat exchanger 40.

  Further, the condensate that has flowed into the second heat exchanger 40 flows into the upper end portion of the second steam channel 42 that extends in the vertical direction, and flows downward along the second steam channel 42. That is, the condensate that has flowed into the second steam channel 42 flows down along the second steam channel 42 in the direction of gravity. As a result, the condensate that has flowed into the second steam channel 42 is likely to flow along the second steam channel 42.

  In addition, the condensate in the second steam channel 42 is pumped to the tank 60 by a pump 64 provided in the condensate circulation line 18. Therefore, since the condensate stays in the second steam flow path 42 is suppressed, a decrease in the cooling efficiency of the second heat exchanger 40 is suppressed.

  Furthermore, the first refrigerant flow path 26 and the second refrigerant flow path 46 are connected, and the refrigerant flowing through the second refrigerant flow path 46 is caused to flow to the first refrigerant flow path 26, whereby the first refrigerant flow path 26 and Compared with the configuration in which separate refrigerant flows through the second refrigerant flow path 46, the temperature of the refrigerant flowing through the second refrigerant flow path 46 is lower than the temperature of the refrigerant flowing through the first refrigerant flow path 26, and the device structure is It can be simplified.

  Next, a modification of the condenser 12 according to this embodiment will be described.

  In the above embodiment, the channel length (vertical length) of the first steam channel 22 and the channel length (vertical length) of the second steam channel 42 are substantially the same, but not limited thereto. . The second steam channel 42 has a cooling area (heat exchange area) for cooling the steam so that the vapor pressure in the second steam channel 42 is smaller than the steam pressure in the first steam channel 22. For example, the channel length of the second steam channel 42 may be shorter than the channel length of the first steam channel 22.

Moreover, in the said embodiment, although the two 1st heat exchangers 20 and the 2nd heat exchanger 40 were provided in the condenser 12, you may provide three or more cooling parts in the condenser 12. FIG .

  Furthermore, in the said embodiment, although the 1st heat exchanger 20 and the 2nd heat exchanger 40 were comprised separately, even if it comprises the 1st heat exchanger 20 and the 2nd heat exchanger 40 integrally, it is. good. For example, in the condenser 82 shown in FIG. 4, the steam fins 86 that form the steam flow paths 84 and the refrigerant fins 90 that form the coolant flow paths 88 are alternately stacked in the horizontal direction, and the steam fins 86. The upper portions 86 </ b> A and 90 </ b> A of the refrigerant fin 90 serve as the first cooling unit 92, and the lower portions 86 </ b> B and 90 </ b> B of the vapor fin 86 and the refrigerant fin 90 serve as the second cooling unit 94. Although not shown, a metal partition plate that partitions the steam channel 84 and the coolant channel 88 is disposed between the steam fin 86 and the coolant fin 90.

  The refrigerant flow paths 88 in the second cooling section 94 and the refrigerant flow paths 88 in the first cooling section 92 are connected via the refrigerant circulation line 54, and the vapor flow paths 84 in the second cooling section 94 are connected to each other. The flowing steam or the like is cooled at a lower temperature than the steam or the like flowing through the steam flow path 84 in the first cooling unit 92.

  Thus, by comprising the 1st cooling part 92 and the 2nd cooling part 94 integrally, an apparatus structure can be simplified and size reduction of the condenser 82 can be achieved.

  Moreover, in the said embodiment, although the 1st heat exchanger 20 and the 2nd heat exchanger 40 were arranged in the up-down direction, for example, the 1st heat exchanger 20 and the 2nd heat exchanger 40 are arranged in the horizontal direction. May be. The first heat exchanger 20 and the second heat exchanger 40 are arranged with the longitudinal direction of each of the first steam channel 22 and the second steam channel 42 in the vertical direction. You may arrange | position with the longitudinal direction of the steam flow path 22 and the 2nd steam flow path 42 being a horizontal direction.

  Furthermore, in the said embodiment, although the 1st refrigerant flow path 26 and the 2nd refrigerant flow path 46 were connected by the refrigerant | coolant circulation line 54, the 1st refrigerant flow path 26 and the 2nd refrigerant flow path 46 were not connected, Separate refrigerants may flow through the first refrigerant channel 26 and the second refrigerant channel 46. In this configuration, the temperature of the refrigerant supplied to the second refrigerant channel 46 may be lower than the temperature of the refrigerant supplied to the first refrigerant channel 26.

  As mentioned above, although one embodiment of the present invention was described, the present invention is not limited to such an embodiment, and one embodiment and various modifications may be used in combination as appropriate, and the gist of the present invention will be described. Of course, various embodiments can be implemented without departing from the scope.
