Background technology
Improve the efficiency of refrigerated air-conditioning system, the compression of the secondary of tonifying Qi or accurate secondary is a kind of than effective and efficient manner in the middle of having.The circulation theory of refrigerated air-conditioning system is as shown in Figure 1.Include compressor 101, four-way change-over valve a102, outdoor heat exchanger 103, check valve 104, capillary a105, capillary b106, four-way change-over valve b107, flash vessel 108, capillary c109, indoor heat exchanger 110.When using as refrigeration; Refrigerant flow direction is expressed by white arrow, and the course of work is following: the exhaust of compressor is introduced into outdoor heat exchanger 103, becomes behind the liquid refrigerant through entering into behind the check valve 104 in the capillary b106; Throttling enters in the flash vessel 108 after being depressurized to a certain intermediate pressure; The gas that shwoot comes out enters into compressor through the tonifying Qi pipeline, and the cold excessively liquid of main road enters into second throttle in the capillary c109, and the vapour-liquid two phase low pressure refrigerants after the throttling enter in the indoor heat exchanger 110; Through airborne heat in the evaporation absorption chamber, reach the effect of refrigeration.The low-pressure gaseous refrigerant that goes out indoor heat exchanger 110 enters into compressor 101 again, accomplishes a kind of refrigeration cycle.
When conduct heated use, refrigerant flow direction was expressed by black arrow, and the course of work is following: the exhaust of compressor is introduced into indoor heat exchanger 110; Heat is discharged to indoor air; Reach the effect that heats, enter in the capillary c109 after gaseous refrigerant becomes liquid state simultaneously, throttling enters in the flash vessel 108 after being depressurized to a certain intermediate pressure; The gas that shwoot comes out enters into compressor through the tonifying Qi pipeline; The cold excessively liquid of main road enters into the interior second throttle of capillary a105 of capillary b106 and series connection with it, and the vapour-liquid two phase low pressure refrigerants after the throttling enter in the outdoor heat exchanger 103, through the heat in the evaporation absorption chamber outer air; The low-pressure gaseous refrigerant that goes out outdoor heat exchanger 103 enters into compressor 101 again, accomplishes one and heats circulation.
Wherein, one of critical component is a flash vessel, and the flash vessel structure of function admirable should be able to satisfy following performance:
1) gets into the abundant shwoot of liquid refrigerant in the flash vessel, make gas flow behind the shwoot satisfy the demand of air compensation;
2) sub-cooled liquid refrigerant that forms after the flash distillation can in time flow out, and does not occupy the flash distillation space, and the flash distillation of liquid towards cold-producing medium does not continue to produce interference;
3) not extra increase resistance does not have moving component, suitable long-time the use.
Summary of the invention
