Abstract
The invention relates to an outdoor machine of an air conditioner, which is provided with a water-cooling heat transfer module. The water-cooling heat transfer module is used for enabling water and cooling medium passing through an external heat exchanger to carry out heat exchange. When the air conditioner is operated to cool, the supercooling degree of the cooling medium passing through the external heat exchanger is increased so as to improve the condensing factor. When the air conditioner is operated to heat, the superheat degree of the cooling medium is increased so as to improve evaporative efficiency. Thus, the invention has the effect of improving the cooling and heating performance of the air conditioner.

The specific embodiment
Below, with embodiments of the invention in conjunction with the accompanying drawings, explained.
Fig. 1 is the schematic diagram of air-conditioner outdoor unit of the present invention.Fig. 2 is the schematic diagram of the open state of casing of outdoor body shown in Figure 1.Fig. 3 is the heat exchanger shown in Figure 2 and the decomposing schematic representation of water-cooled heat transfer module.Fig. 4 is the A-A sectional view of Fig. 2.
As shown in Figure 1, the off-premises station 1 of the embodiment of the invention is to be made of following part: the shell body 10 that forms outward appearance; Be combined in the chassis 20 of shell body 10 bottoms; Be used to connect and being connected of off-premises station 1 and indoor set (not shown) use coolant piping 21; Be combined in and connect, and be used to control the come in and go out auxiliary valve 22 of shell body 10 inside of refrigerant with coolant piping 21.
As shown in Figure 2, the inside of shell body 10 is provided with following part: the pressure fan 23 that can produce air-supply power; The compressor 24 that is used for compression refrigerant; Make at compressor 24 compressed refrigerants and the outdoor heat converter 30 that carries out heat exchange by air suction inlet (not shown) inhaled air.
The air cooling heat exchanger that outdoor heat converter 30 is made up of fin and pipe, and be provided with the refrigerant mobile a plurality of refrigerant pipes 32 of portion within it.
Simultaneously, as Fig. 2 and shown in Figure 3, a side of outdoor heat converter 30 is formed with refrigerant pipe 32 carries out the water-cooled heat transfer module 40 that heat exchange is used.
Water-cooled heat transfer module 40 is arranged on outdoor heat converter 30, and with the corresponding arrangement of bend of refrigerant pipe 32.
Water-cooled heat transfer module 40 is to be made of following part: be combined in outdoor heat converter 30, and its inside can store the container 41 of water; Be arranged on the container 41, and water supplied to the water inlet 42 of container 41 inside from the outside; Be arranged on the container 41, and be used for the discharge outlet 43 of amount discharge container 41 internal water; Be arranged on water inlet 42 1 sides, and can control the valve 44 of the water that supplies to container 41 inside.
Below, the effect of the embodiment of the invention that constitutes as mentioned above is described.
At first, when above-mentioned air-conditioner carried out cooling operation, the refrigerant of compressed HTHP flow into outdoor heat converter 30 in compressor 24.At this time, outdoor heat converter 30 plays the effect of condenser,, when refrigerant by outdoor heat converter 30 and extraneous air carry out heat exchange, carries out heat release that is.
Water supplies to container 41 inside of water-cooled heat transfer module 40.Here, the water that supplies to container 41 inside can use running water.Since running water summer its temperature also can not surpass 20 degrees centigrade, therefore can be used as cooling water, thereby supercooling fully is by the refrigerant of the HTHP of outdoor heat converter 30.
Since water inlet 42 and discharge outlet 43 all be formed on container 41 above, therefore, when the water of container 41 inside long-pending full after, can overflow by discharge outlet 43.The water that overflows flows to chassis 20, and is discharged to the outside.
The bend of container 41 internal water and refrigerant pipe 32 carries out heat exchange.That is, when the HTHP refrigerant of the internal flow of refrigerant pipe 32 and air outside were carried out heat exchange, also the water with internal tank 41 carried out heat exchange.In aforesaid heat exchanging process, the heat of refrigerant is further taken away.
Therefore, can be fully the refrigerant of above-mentioned refrigerant pipe 32 inside be carried out supercooling.
Fig. 5 is the Mollier chart that shows the kind of refrigeration cycle of embodiment of the invention air-conditioner.As shown in Figure 5, by the refrigerant of outdoor heat converter 30, under the effect of water-cooled heat transfer module 40 once more by supercooling.Therefore, circulation of the present invention is compared with the circulation in the prior art, and its condensation efficiency and refrigerating efficiency are improved.
,, expanded when being arranged on the expansion mechanism of indoor set by overcooled refrigerant at water-cooled heat transfer module 40.Afterwards, in the time of indoor heat converter (not shown) by being arranged on indoor set, carry out heat exchange with room air.At this time, indoor heat converter (not shown) plays the effect of evaporimeter, that is, by airborne heat in the refrigerant absorption chamber of indoor heat converter (not shown), thereby realize indoor refrigeration.
On the contrary, when air-conditioner heats running, by in the indoor heat converter (not shown), carry out condensation at compressor 24 compressed refrigerants.Afterwards, under the effect of expansion mechanism (not shown), expand, thereby become the state of low-temp low-pressure.The refrigerant of low-temp low-pressure flow into outdoor heat converter 30, and at this time, outdoor heat converter 30 plays the effect of evaporimeter.
Flow into the refrigerant of outdoor heat converter 30, when carrying out heat exchange with extraneous air, also the water with container 41 inside of water-cooled heat transfer module 40 carries out heat exchange.At this time, because the temperature of the refrigerant that flows at outdoor heat converter 30 is below zero degrees celsius, so the temperature of refrigerant is lower than the temperature of container 41 internal water all the time.That is, refrigerant can absorb heat fully from the water of container 41 inside, thereby realizes heating.
Therefore, water-cooled heat transfer module 40 can play the effect that the refrigerant by outdoor heat converter 30 is heated fully.Because under the effect of water-cooled heat transfer module 40, refrigerant is further heated, therefore can increases the degree of superheat, thereby improve heating efficiency.
Fig. 6 is the Mollier chart that heats circulation that shows embodiment of the invention air-conditioner.
As shown in Figure 6, by the refrigerant of outdoor heat converter 30, under the effect of water-cooled heat transfer module 40 once more by overheated, thereby can improve evaporation efficiency.
By overheated refrigerant, be drawn into compressor at water-cooled heat transfer module 40.At this time, under the effect of water-cooled heat transfer module 40, the temperature and pressure that is drawn into the refrigerant of compressor 24 can increase.Therefore compressor 24 needed power can be reduced, thereby the power consumption of air-conditioner can be reduced.
In addition, according to the load-up condition of indoor and outdoor,, can regulate the flow of container 41 inside by control valve 44.
