Description of reference numerals: 1-compressor, 2-cross valve, 3-finned heat exchanger, 4-blower fan, 5-the first electric expansion valve, 6-super cooled sect (A-B section), 7-liquid storage valve, 8-the second electric expansion valve, 9-heat exchanger, 10-vapour liquid separator.
The specific embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises compressor 1, and compressor 1 is by cross valve 2 difference connecting fin plate heat interchanger 3 and heat exchangers 9.
Finned heat exchanger 3 rear ends connect super cooled sect 6, are provided with the first electric expansion valve 5 between finned heat exchanger 3 and super cooled sect 6.Described super cooled sect 6 rear ends connect liquid storage valve 7, and liquid storage valve 7 rear ends connect heat exchanger 9 by the second electric expansion valve 8.
Described finned heat exchanger 3 one sides are provided with blower fan 4, and finned heat exchanger 3 heat exchange are strengthened in blower fan 9 forced convertions.
On described compressor 1, connect vapour liquid separator 10, vapour liquid separator 1 one end connects cross valve 2.
Described heat exchanger 9 adopts finned heat exchanger, plate type heat exchanger, double-tube heat exchanger or pipe heat exchanger.
Operation principle of the present utility model is: the machine has refrigeration and heating mode, and during refrigeration work pattern, the refrigerant vapour of low-temp low-pressure is compressed into the steam of HTHP through compressor, through cross valve, discharged to finned heat exchanger.Cooling in finned heat exchanger, and strengthen heat exchange through blower fan forced convertion, be condensed into the liquid of HTHP.Through the first electric expansion valve (expansion valve is full-gear), again cooling through super cooled sect, then through reservoir, through the second electric expansion valve, step-down throttling, and then discharged to heat exchanger, in heat exchanger, flash to the gas of low-temp low-pressure, periodic duty.
While heating mode of operation, the refrigerant vapour of low-temp low-pressure is compressed into the steam of HTHP through compressor, through cross valve commutation, discharged to heat exchanger, cooling in heat exchanger, to be condensed into HTHP liquid, through the second electric expansion valve (expansion valve is full-gear), then through reservoir, then it is again cooling to pass through super cooled sect.After super cooled sect is again cooling, through electric expansion valve step-down throttling, and then discharged to finned heat exchanger, and strengthen heat exchange through blower fan forced convertion, in heat exchanger, flash to the gas of low-temp low-pressure, periodic duty.
The utility model increases super cooled sect in finned heat exchanger bottom, no matter make unit is refrigeration or super cooled sect can be realized cold-producing medium was carried out to cold effect while heating.When heating operation, super cooled sect not only works to be cold cold-producing medium, and because super cooled sect is positioned at the bottom of finned heat exchanger, therefore can improve the surface temperature of bottom fin, extend the time of its frosting and reduce the thickness of frost layer, thereby reach, reduce the number of times of defrosting and the object of the time of defrosting.Net for air-source heat pump units can be stablized and operation for a long time in winter, reduced unnecessary energy consumption.
