The specific embodiment
Below, utilize the description of drawings embodiments of the invention.
Embodiment 1
Utilize Fig. 1~Fig. 5, Fig. 7 that the first embodiment of the present invention is described.At first, the basic structure of the air regulator of the present embodiment described.Fig. 2 is the structure chart of freeze cycle.The air regulator of the present embodiment is practical function by connect off-premises station 1 and indoor set 7 with connecting pipings 10.Off-premises station 1 possesses: compressor 2, cross valve 3, outdoor heat converter 4, throttling arrangement 6 and propeller fan 5.Indoor set 7 possesses: indoor heat converter 8 and Air Blast fan.And, can use DC fan 9 as Air Blast fan.
Below, at first the effect of each inscape when cold air operation is described.The gas shape refrigerant of the high pressure that is compressed by compressor 2, by utilizing outdoor heat converter 4 to condense to the extraneous air heat release, becomes the liquid refrigerant of high pressure.This liquid refrigerant is depressurized by the effect of throttling arrangement 6, becomes the gas-liquid two-phase state of low-temp low-pressure, by connecting pipings 10, flows to indoor set 7.The refrigerant that enters into indoor set 7 absorbs heat and evaporates by the heat of utilizing 8 pairs of room airs of indoor heat converter.Refrigerant by the indoor unit evaporation turns back to off-premises station 1 by connecting pipings 10, by cross valve 3, again by compressor 2, is compressed.
In heating installation when running,, with cross valve 3 switching refrigerant runners, the gas shape refrigerant of the high pressure that is compressed by compressor 2 flows to indoor set 7 by cross valve 3 and connecting pipings 10.Enter the refrigerant of indoor set 7 by utilizing indoor heat converter 8 to condense to the room air heat release, become the liquid refrigerant of high pressure.This liquid refrigerant flows to off-premises station 1 by connecting pipings 10.The liquid refrigerant that enters off-premises station 1 is depressurized by the effect of throttling arrangement 6, becomes the gas-liquid two-phase state of low-temp low-pressure.The cryogen flow that becomes the gas-liquid two-phase state of low-temp low-pressure arrives outdoor heat converter 4, by the heat of absorption chamber outer air, evaporates, and becomes gas shape refrigerant.This gas shape refrigerant is compressed by compressor 2 again by cross valve 3.
Fig. 3 represents to intersect the structure of heat exchanger of fin-tube type.This heat exchanger is connected a plurality of aluminum thermal fins 11 and is formed by the copper heat-transfer pipe 12 that bends to the U font.Mode by hydraulic pressure or machinery is carried out expander to the heat-transfer pipe 12 that is inserted into fin, thereby fin 11 and heat-transfer pipe 12 are close to.And, be welded with joint part 13 in the end of heat-transfer pipe 12, form the runner of refrigerant.
Fig. 4 is the cutaway view (perpendicular to the section of the axle of heat-transfer pipe) of the indoor set of air regulator.The top of framework be provided with air suction inlet (specifically, in the front of framework, be provided with front air suction inlet 22, and be provided with on framework above air suction inlet 23), be provided with Air blowing mouth 24 below framework.Be equipped with DC fan 9 in framework, be equipped with the heat exchanger of intersection fin-tube type the way in the air channel from this air suction inlet to DC fan.Indoor heat converter 8 consists of heat exchanger 21 in front face side indoor heat converter 20 and side room, back.And in front face side indoor heat converter 20 and side room, back, heat exchanger 21 is adapted to roughly inverted v-shaped, to surround DC fan 9.While starting DC fan 9,, because room air flows into from air suction inlet, utilize indoor heat converter 8 and inner refrigerant to carry out heat exchange, and from Air blowing mouth 24, blow out, thereby room air is carried out air conditioning.
Next, utilize Fig. 5 to describe the detailed section shape of front face side indoor heat converter 20.The windward exterior region of heat exchanger 20 in side room in front, front edge side line part 25 are connected with the front edge side line part and are connected by front edge side curve part 28, and front edge side line part 26 is connected with the front edge side line part and is connected by front edge side curve part 29.And the leeward hinder marginal part of heat exchanger 20 in side room in front, trailing edge side line part 30 are connected with trailing edge side line part and are connected by trailing edge lateral bending pars convoluta 33, and trailing edge side line part 31 is connected with trailing edge side line part and is connected by trailing edge lateral bending pars convoluta 34.Adopt this structure, the front face side indoor heat converter forms agley to the direction of DC fan 9.
The hachure section of Fig. 5 upside represents the heat exchanger curve part 35 that is surrounded by the trailing edge lateral bending pars convoluta 33 of the front edge side bend 28 of windward leading edge and leeward trailing edge.And the hachure section of Fig. 5 downside represents the heat exchanger curve part 36 that is surrounded by the trailing edge side curve part 34 of the front edge side bend 29 of windward leading edge and leeward trailing edge.There is no the part of hatching by the heat exchanger line part 50 of trailing edge side line part 30 encirclements of the front edge side line part 25 of windward leading edge and leeward trailing edge, by the heat exchanger line part 51 of trailing edge side line part 31 encirclements of the front edge side line part 26 of windward leading edge and leeward trailing edge, by the heat exchanger line part 52 of trailing edge side line part 32 encirclements of the front edge side line part 27 of windward leading edge and front edge side leeward trailing edge.At this, the two ends of heat exchanger curve part 35 are connected in heat exchanger line part 50 and heat exchanger line part 51, and the two ends of heat exchanger curve part 36 connect and heat exchanger line part 51 and heat exchanger line part 52.As utilize the explanation of Fig. 7, heat exchanger curve part 35,36 easily accelerates flowing of air than heat exchanger line part 50,51,52.
Next, utilize Fig. 1 to describe the configuration of the heat-transfer pipe of the section of the front face side indoor heat converter 20 of the present embodiment.In side room in heat exchanger 20, the flow direction configuration three biographies heat pipes along air, dispose Floor 12 in the rectangular direction of the flow direction with air in front.Dotted line in figure represents that the heat-transfer pipe that is inserted into bends to the part of U font.Here L0 represents the configuration space of the heat-transfer pipe of heat exchanger line part.L1 and L2 represent the configuration space of heat-transfer pipe minimum in the configuration space of heat-transfer pipe of heat exchanger curve part 35 and heat exchanger curve part 36.In the present embodiment, the relation of L0, L1, L2 is shown below.
L1<L0
L2<L0
Namely, the air easily configuration space of accelerated heat exchanger curve part 35,36 heat-transfer pipe is narrower than the configuration space of heat exchanger line part 50,51,52 heat-transfer pipe,, because heat exchanger curve part 35,36 flowing resistance are relatively larger, can suppress the acceleration of heat exchanger curve part 35,36 air stream.That is, the wind speed profile that can reduce the air by heat exchanger is inhomogeneous, can with improve energy saving and realize quietization both.
In order to increase heat exchanger curve part 35,36 flowing resistance, the configuration space of heat-transfer pipe that can be by dwindling any row in first row to the three row is realized.But during cold air operation, air turns cold, and airborne moisture is condensed, and while producing dewfall on the fin of heat exchanger, the part of passing through due to the highest air of humidity is first row, thereby adheres to more dew on the fin of first row.While adhering to dew on fin, the part that can pass through due to air reduces, and flowing resistance can increase.That is, while by the configuration space that dwindles pipe, increasing flowing resistance, as the present embodiment, the configuration space of the heat-transfer pipe of the first row by dwindling windward is more effective.
And, in the present embodiment, configuration space by making heat exchanger curve part 35,36 heat-transfer pipe is less than the configuration space of heat exchanger line part 50,51,52 heat-transfer pipe, suppress the easily acceleration of accelerated heat exchanger curve part 35,36 air stream of air, thereby reduced wind speed profile inhomogeneous of the air by heat exchanger.But the present invention is not just as the present embodiment, formed by the indoor heat converter with heat exchanger line part and heat exchanger curve part, even the occasion that only by the heat exchanger curve part, is formed not possessing the heat exchanger line part, curvature by this heat exchanger curve part changes, produce the zone that air easily accelerates, also effective to the inhomogeneous occasion of the wind speed profile of the air by indoor heat converter.As long as make the configuration space of heat-transfer pipe of the configuration space of heat-transfer pipe of the larger part of the curvature of the front face side heat exchanger part less than the curvature of front face side heat exchanger little in this occasion.Make the configuration space of heat-transfer pipe of the configuration space of heat-transfer pipe of the larger part of the curvature of the front face side heat exchanger part less than curvature little due to utilization, can prevent the acceleration of the air stream of the air part that easily accelerated curvature is less, thereby it is inhomogeneous to reduce the wind speed profile of the air by heat exchanger.
And, as utilizing Fig. 3 description, the heat exchanger of intersection fin-tube type is owing to having used the heat-transfer pipe that bends to the U font, in order to make the configuration space difference of heat-transfer pipe, need to make the bending radius of the heat-transfer pipe that bends to the U font different (that is, needs to prepare multiple heat-transfer pipe.)。But, in the present embodiment, configuration space by the heat-transfer pipe of adjacency in the heat-transfer pipe that dwindles two U fonts (that is, because the heat-transfer pipe of the U font with adjacency is adjusted to L0, L1, L2), just can not need multiple heat-transfer pipe and only with a kind of heat-transfer pipe of U font, form heat exchanger.
Embodiment 2
Utilize Fig. 6 that the second embodiment of the present invention is described.Because the basic structure of the air regulator of the present embodiment is identical with the first embodiment, therefore omitted detailed explanation, only difference is described.
Fig. 6 represents the configuration of heat-transfer pipe of the front face side indoor heat converter of the present embodiment.In the front face side indoor heat converter of the present embodiment, the flow direction configuration three biographies heat pipes along air, dispose Floor 12 in the rectangular direction of the flow direction with air.Dotted line in figure represents that the heat-transfer pipe that is inserted into bends to the part of U font.Here L0 represents the configuration space of the heat-transfer pipe of heat exchanger line part.L1 and L2 represent the configuration space of heat-transfer pipe minimum in the configuration space of heat-transfer pipe of heat exchanger curve part 35 and heat exchanger curve part 36.In the present embodiment, the relation of L0, L1, L2 and the first embodiment similarly are shown below.
L1<L0
L2<L0
Namely, easily the configuration space of accelerated heat exchanger curve part 35,36 heat-transfer pipe is narrower than the configuration space of heat exchanger line part 50,51,52 heat-transfer pipe due to air, heat exchanger curve part 35,36 flowing resistance are relatively large, thereby can suppress the acceleration of heat exchanger curve part 35,36 air stream.That is, the wind speed profile that can reduce the air by heat exchanger is inhomogeneous, can be with improving energy saving and realizing both effects of quietization.
In the present invention, in the first embodiment, the part that bends to the U font of the heat-transfer pipe part of dotted line (in the Fig. 6 draw) is not present in the little part of the configuration space of heat-transfer pipe.But in the present embodiment, the part that bends to the U font of the heat-transfer pipe part of dotted line (in the Fig. 6 draw) is present in the little part of the configuration space of heat-transfer pipe.That is,, by using the bending radius heat-transfer pipe 40 less than other heat-transfer pipes of U character segment, reduced the arrangement pitch of heat-transfer pipe.
