Description
Technical Field
The present invention relates to an air conditioning unit provided on a ceiling of a vehicle.
Background
For example, in a vehicle such as a small electric vehicle, in order to secure a sufficient travel distance, it is required to reduce power consumption of an air conditioning unit for supplying cooling air to a vehicle cabin. Therefore, it is preferable to provide an outlet for the cooling air at a position close to the passenger riding in the vehicle so as to efficiently supply the cooling air to the passenger, or to provide an evaporator near the outlet so as to reduce the piping distance as much as possible. In order to arrange the air outlet or the evaporator in this manner, it is conceivable to provide the air conditioning unit on the ceiling of the vehicle, as described in japanese patent application laid-open No. 2005-125896, for example.
However, an air conditioning unit installed on the ceiling of a vehicle is susceptible to thermal influence caused by sunlight. Thus, if the temperature of the evaporator and the temperature of the cooling air heat-exchanged with the refrigerant in the evaporator increase or the heat radiation of the refrigerant in the condenser is hindered, the cooling efficiency of the air conditioning unit may decrease. Therefore, it is necessary to suppress the evaporator, the condenser, and the like from being affected by the above thermal influence, thereby suppressing the decrease in cooling efficiency.
However, if a large cooling fan or the like capable of sufficiently suppressing the thermal influence is provided on the ceiling, a problem such as a significant increase in vehicle height occurs. Therefore, in the air conditioning unit described in japanese patent application laid-open No. 2005-125896, in order to take in the traveling wind of the vehicle from the opening on the vehicle front side of the air conditioning casing covering each component to cool the condenser, the condenser is disposed on the vehicle front side (upstream side of the traveling wind) in the air conditioning casing.
Disclosure of Invention
As described above, in the air conditioning unit in which the condenser is disposed on the front side of the vehicle, the evaporator is disposed on the downstream side of the traveling wind with respect to the condenser, and the traveling wind that has been heated by heat exchange with the condenser flows toward the evaporator. In this case, since the evaporator or the cooling air is not sufficiently suppressed from being affected by the heat generated by the solar radiation, and may also be affected by the heat generated by the condenser, it is difficult to suppress a decrease in the cooling efficiency of the air conditioning unit.
A main object of the present invention is to provide an air conditioning unit that exhibits good cooling efficiency even when installed on the ceiling of a vehicle.
According to one embodiment of the present invention, there is provided an air conditioning unit provided on a ceiling of a vehicle, the air conditioning unit including: an air-conditioning roof panel that covers at least a part of the roof and forms a traveling wind path between the air-conditioning roof panel and the roof, the traveling wind path allowing traveling wind to pass rearward from the front of the vehicle; a cooling passage disposed in an upper portion of a cabin of the vehicle and below the air-conditioning roof panel so as to be capable of exchanging heat with air in the traveling wind passage; an evaporator provided in the cooling path; and a condenser disposed in the traveling wind path and behind the vehicle with respect to the cooling path.
In this air conditioning unit, air in the vehicle cabin is taken into the cooling passage from one end side of the cooling passage, and the air is cooled by an evaporator provided in the cooling passage to become cooling air. The cooling air is sent from the other end side of the cooling passage to the vehicle cabin, and the vehicle cabin is cooled. In this way, the cooling passage in which the evaporator is provided and cooling air flows is disposed in the upper portion of the vehicle cabin and in the lower portion of the air-conditioned ceiling panel so as to be capable of exchanging heat with air such as traveling air (hereinafter also collectively referred to as traveling air) passing through the traveling air passage. The "upper portion of the vehicle compartment" herein is either the inside or the outside of the vehicle compartment. Further, in the traveling wind path, a condenser is disposed on the rear side of the vehicle with respect to the cooling path, in other words, on the downstream side of the traveling wind.
Therefore, when the vehicle travels, the cooling passage disposed on the upstream side of the traveling wind first comes into contact with the traveling wind in the traveling wind passage. At this time, the traveling wind does not contact the condenser, and therefore, the traveling wind is relatively low in temperature. Therefore, the cooling path and the evaporator can be prevented from being affected by sunlight or heat generated by the condenser, and more specifically, the temperature of the evaporator or the cooling air can be prevented from increasing, and the cooling efficiency of the vehicle cabin can be prevented from decreasing.
Further, the cooling passage is configured to insulate the inside and outside of the cooling passage in order to suppress a temperature rise of the evaporator or the cooling air. However, the cooling air having a lower temperature than the outside flows through the cooling passage, and accordingly, the temperature in the vicinity of the cooling passage tends to be relatively low. Therefore, the traveling wind passing through the vicinity of the cooling path is cooled, and the temperature is lowered. The cooled traveling wind flows to the condenser. This effectively suppresses the influence of heat generated by sunlight on the condenser, and the like, and the traveling wind is cooled, and accordingly, the heat radiation of the refrigerant in the condenser can be more favorably promoted.
As described above, the air conditioning roof is disposed apart from the cooling path and the condenser at a predetermined interval to form the traveling wind path. Therefore, the solar radiation can be blocked by the air-conditioning ceiling plate, and the transmission of the solar radiation heat to the cooling passage or the condenser can be suppressed by the air layer between the air-conditioning ceiling plate and the cooling passage or the condenser.
As described above, the air conditioning unit according to the present invention can effectively suppress the influence of sunlight-generated heat and the like and maintain good cooling efficiency of the vehicle cabin even when installed on the ceiling of the vehicle. In this case, since it is not necessary to provide a large cooling fan or the like on the ceiling, the vehicle height does not increase excessively.
That is, in this air conditioning unit, it becomes easy to provide an outlet port for cooling air at a position close to a passenger riding in a vehicle so as to efficiently supply the cooling air to the passenger, and to provide an evaporator in the vicinity of the outlet port so as to shorten the piping distance as much as possible. This can reduce power consumption of the air conditioning unit. Therefore, when the air conditioning unit is applied to a vehicle such as a small electric vehicle, for example, the travel distance of the vehicle is easily extended. Further, the air conditioning unit can be disposed on the ceiling, and accordingly, a wide cabin space can be easily secured.
In the above air conditioning unit, it is preferable that at least a part of a partition wall forming the cooling passage is provided in the traveling wind passage, and the traveling wind is caused to pass between the partition wall and the air conditioning ceiling panel and between the ceiling and the air conditioning ceiling panel. In this case, the partition wall forming the cooling passage can be brought into contact with the traveling wind efficiently in the traveling wind passage, and the cooled traveling wind can be sent to the condenser, so that the heat radiation of the refrigerant in the condenser can be promoted more favorably.
In the air conditioning unit, it is preferable that at least a part of a partition wall forming the cooling passage provided in the cabin is formed by a part of the ceiling. In this case, the traveling wind can be efficiently brought into contact with the partition wall, that is, a part of the ceiling, and the distance between the air-conditioning ceiling and the cooling path can be increased to increase the air layer. This can promote heat dissipation of the refrigerant in the condenser, and can effectively suppress transmission of solar radiation heat to the cooling path.
In the air conditioning unit, it is preferable that at least a part of a partition wall forming the cooling passage is provided in the vehicle compartment so as to be in contact with or close to the ceiling, and the cooling passage and the air in the traveling wind passage can exchange heat via the ceiling. In this case, since the cooling passage is covered with both the ceiling and the air-conditioning ceiling, the transmission of solar heat to the cooling passage can be suppressed more effectively.
In the above air conditioning unit, it is preferable that the air conditioning unit further includes a compressor provided in the traveling wind path. In this case, since the compressor can be cooled by the traveling wind as well, overheating of the compressor can be avoided, and the air conditioning unit can be operated more stably.
In the air conditioning unit described above, it is preferable that the compressor is disposed on a rear side of the vehicle with respect to the cooling passage. In this case, the compressor can be cooled more efficiently using the traveling wind cooled by passing through the periphery of the cooling passage.
In the above air conditioning unit, it is preferable that a blower that takes in outside air and circulates the air through the traveling wind path is provided in the ceiling. In this case, the traveling wind can be more favorably circulated in the traveling wind passage by the blower during traveling of the vehicle. On the other hand, even when the vehicle is stopped, the outside air can be taken in by the blower and circulated through the traveling wind path, and therefore, the cooling path, the evaporator, the condenser, and the like can be effectively prevented from being affected by heat generated by sunlight and the like.
The above objects, features and advantages will become more apparent from the following description of preferred embodiments taken in conjunction with the accompanying drawings.

Detailed Description
The air conditioning unit of the present invention will be described in detail below with reference to the accompanying drawings by way of preferred embodiments.
As shown in fig. 1, an air conditioning unit 10 according to embodiment 1 of the present invention is installed on a ceiling 12 of a vehicle and performs air conditioning of a cabin 14 of the vehicle. A preferable example of the vehicle to which the air conditioning unit 10 is applied is a small electric vehicle, but the present invention is not particularly limited thereto. The front-back and up-down directions will be described below based on the directions of arrows shown in fig. 1. "front" is the direction of travel of the vehicle and "rear" is the opposite direction.
The air conditioning unit 10 mainly includes: an air conditioner top panel 20; a cooling passage 22 formed by the partition wall 21; a refrigerant cycle device (refrigeration cycle device) 24; and a 1 st blower (blower) 26. The air-conditioning roof panel 20 covers at least a part of the ceiling 12 in a state of being separated from the ceiling 12 and the partition wall 21 by a predetermined interval. Thus, a traveling wind passage 28 for passing traveling wind rearward from the front of the vehicle is formed between the air-conditioning roof panel 20 and the ceiling 12 and the partition wall 21. That is, between the air-conditioning ceiling panel 20 and the ceiling 12, an inflow port 30 for traveling wind is formed on the front end side in the front-rear direction, and an outflow port 32 for traveling wind is formed on the rear end side in the front-rear direction.
The partition wall 21 forming the cooling passage 22 is formed of a heat insulating material, and insulates the inside and outside of the cooling passage 22 from heat. The cooling passage 22 is provided in the traveling wind passage 28 and communicates with the cabin 14. Specifically, one end side of cooling passage 22 is connected to an intake port (not shown) for taking air of vehicle cabin 14 into cooling passage 22, and the other end side of cooling passage 22 is connected to an outlet port (not shown) for blowing cooling air from cooling passage 22 to vehicle cabin 14.
The 2 nd blower 34 and an evaporator 40 constituting the refrigerant cycle device 24 as described later are provided inside the cooling passage 22. The 2 nd blower 34 circulates air between the cabin 14 and the cooling path 22. That is, by driving the 2 nd blower 34, the air in the vehicle cabin 14 is taken into the cooling passage 22 from the intake port, and the air is blown out into the vehicle cabin 14 from the blow-out port after flowing through the cooling passage 22.
The positions where the intake port and the air outlet are provided are not particularly limited, but for example, the intake port is preferably provided below a seat (both not shown) of the vehicle via a pipe or the like. In this case, the air in the vehicle compartment 14 can be circulated more favorably. Further, the air outlet is preferably provided at a position close to a passenger riding in the vehicle. In this case, the cooling air can be efficiently supplied to the passenger.
The refrigerant cycle device 24 has a structure in which a compressor 42, a condenser 44, an expansion valve (not shown), and an evaporator 40 are connected in this order via refrigerant pipes (not shown), and these structures are provided in the traveling air passage 28 or in the vehicle cabin 14, respectively. The compressor 42 is disposed on the vehicle rear side of the cooling passage 22, and compresses the refrigerant. The condenser 44 is disposed on the rear side of the vehicle with respect to the cooling path 22 and the compressor 42, and cools and liquefies the refrigerant compressed by the compressor 42 by exchanging heat with traveling wind or the like. The expansion valve decompresses the liquefied refrigerant and adiabatically expands the refrigerant.
As described above, the evaporator 40 is disposed in the cooling passage 22, and therefore, is disposed on the front side of the vehicle with respect to the condenser 44. The evaporator 40 exchanges heat between the refrigerant that has reached a low temperature via the expansion valve and the air taken into the vehicle cabin 14 in the cooling passage 22, thereby cooling the air to form cooling air.
The 1 st air blower 26 is disposed, for example, near the outlet 32 in the traveling wind path 28. Further, by driving the 1 st air blower 26 during traveling of the vehicle, traveling wind can be more favorably distributed in the traveling wind path 28. Further, by driving the 1 st air blower 26 when the vehicle is stopped, outside air can be taken in and circulated in the traveling wind path 28. The 1 st air blower 26 may be disposed at any position as long as it can promote the flow of the traveling wind or the outside air in the traveling wind path 28, and may be disposed, for example, near the inflow port 30 in the traveling wind path 28. In the case where the 1 st fan 26 is disposed in the vicinity of the outlet 32 in the traveling wind path 28, the traveling wind or the outside air taken into the traveling wind path 28 may be caused to flow out toward the rear of the vehicle or may be caused to flow out toward the upper side of the vehicle.
The air conditioning unit 10 of embodiment 1 is basically configured as described above. Next, the operational effects will be described based on the relationship with the operation of the air conditioning unit 10.
When the air conditioning unit 10 cools the cabin 14, the refrigerant cycle device 24 is driven to change the state while circulating the refrigerant in the refrigerant piping as described above. The 2 nd blower 34 in the cooling passage 22 is driven to take the air in the cabin 14 into the cooling passage 22 from the intake port. In the cooling path 22, the air is cooled by the evaporator 40 to obtain cooling air, and the cooling air is blown out from the air outlet to the vehicle cabin 14. By circulating air between the vehicle cabin 14 and the cooling passage 22 in this way, the vehicle cabin 14 can be cooled.
At this time, when the vehicle is traveling, the traveling wind flows through the traveling wind path 28 from the front side to the rear side of the vehicle. When the vehicle is stopped, the 1 st air blower 26 is driven to take in outside air and circulate the air through the traveling wind path 28 from the front side to the rear side of the vehicle.
Accordingly, since the cooling path 22 disposed upstream of the traveling wind and the like is subjected to the traveling wind first in the traveling wind path 28, it is possible to suppress thermal influence from sunshine or the condenser 44, specifically, it is possible to suppress a decrease in cooling efficiency of the vehicle cabin 14 due to an increase in temperature of the evaporator 40 or the cooling wind.
Further, as described above, the partition wall 21 of the cooling passage 22 is configured to insulate the inside and the outside of the cooling passage 22, and the temperature inside the cooling passage 22 is lower than the temperature outside, so that the temperature is easily lowered. The traveling wind cooled by passing through the periphery of the cooling passage 22 flows to the compressor 42 and the condenser 44. Therefore, the compressor 42 or the condenser 44 can be cooled while suppressing the influence of heat generated by solar radiation or the like, and accordingly, the heat radiation of the refrigerant in the condenser 44 can be promoted more favorably, and the overheating of the compressor 42 can be effectively avoided.
As described above, since the traveling wind path 28 is formed between the air-conditioning roof panel 20 and the cooling passage 22 and the condenser 44, the air-conditioning roof panel 20 is disposed apart from the cooling passage 22 and the condenser 44 at a predetermined interval. Therefore, the air-conditioning roof panel 20 can block the solar radiation, and the air layer between the air-conditioning roof panel 20 and the cooling passage 22 and the condenser 44 can suppress the transmission of the solar radiation heat to the cooling passage 22 and the condenser 44.
As described above, the air conditioning unit 10 according to the present invention can effectively suppress the influence of heat generated by sun shine and the like even when installed on the ceiling 12 of the vehicle, and can maintain the cooling efficiency of the vehicle cabin 14 well. In this case, since it is not necessary to provide a large cooling fan or the like on the ceiling 12, the vehicle height does not increase excessively.
That is, in the air conditioning unit 10, as described above, it becomes easy to provide an outlet port for cooling air at a position close to a passenger riding in a vehicle so as to efficiently supply the cooling air to the passenger, and to provide the evaporator 40 in the vicinity of the outlet port so as to shorten the piping distance as much as possible. This can reduce power consumption by the air conditioning unit 10. Therefore, when the air conditioning unit 10 is applied to a vehicle such as a small electric vehicle, for example, the travel distance of the vehicle is easily extended. Further, the air conditioning unit 10 can be disposed on the ceiling 12, and accordingly, a wide cabin space and the like can be easily ensured.
The present invention is not particularly limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
For example, as in the air conditioning unit 50 of embodiment 2 shown in fig. 2, a part of the ceiling 12 may constitute a part of the partition wall 52. Among the components shown in fig. 2, those which are the same as or exhibit the same functions and effects as those shown in fig. 1 are given the same reference numerals, and detailed description thereof is omitted.
Specifically, in the air conditioning unit 50, a portion of the partition wall 52 forming a space between one end side and the other end side of the cooling passage 22 is configured to be shared with a portion of the ceiling 12, and the cooling passage 22 is provided in the cabin 14. That is, a traveling wind path 28 through which traveling wind and the like pass is formed between the ceiling 12, which is the partition wall 52, and the air-conditioning ceiling 20. Therefore, the traveling wind and the like can be effectively brought into contact with the cooling passage 22, and the distance between the air-conditioning ceiling 20 and the cooling passage 22 can be increased, thereby increasing the air layer. This can promote heat dissipation of the refrigerant in the condenser 44, and can effectively suppress transmission of solar radiation heat to the cooling passage 22.
Further, for example, as in the air conditioning unit 60 according to embodiment 3 shown in fig. 3, a part of the partition wall 62 may be provided in the cabin 14 so as to be in contact with the ceiling 12. Among the components shown in fig. 3, those that have the same or similar functions and effects as those shown in fig. 1 are given the same reference numerals, and detailed description thereof is omitted.
Specifically, in the air conditioning unit 60, a portion of the partition wall 62 forming between the one end side and the other end side of the cooling passage 22 is in contact with the ceiling 12, and thus the cooling passage 22 can exchange heat with traveling wind and the like via the ceiling 12. Further, the partition 62 may be separated from the ceiling 12 as long as the cooling passage 22 can exchange heat with traveling wind or the like via the ceiling 12.
In the air conditioning unit 60, since the cooling passage 22 is covered with both the ceiling 12 and the air-conditioning ceiling panel 20, it is possible to more effectively suppress the transmission of the solar radiation heat to the cooling passage 22.
In the air conditioning units 10, 50, and 60 according to embodiments 1 to 3 described above, the compressor 42 is disposed between the cooling path 22 and the condenser 44 in the traveling wind path 28, but the position where the compressor 42 is provided is not particularly limited as long as it is in the traveling wind path 28.
Further, although the 1 st air blower 26 is provided in the air conditioning units 10, 50, 60 according to embodiments 1 to 3 described above, the 1 st air blower 26 is not necessarily required. For example, when the thermal influence of sunlight on the evaporator 40, the condenser 44, and the like can be sufficiently suppressed by traveling wind, the air-conditioning roof 20, the air layer, and the like, the 1 st air blower 26 may not be provided.
