It can be understood that the refrigerant from the compressor enters the first recuperating chamber 501 after passing through the first heat exchanger 200, then flows into the throttling element 300 for throttling and depressurizing, then enters the second heat exchanger 400, and returns to the compressor after passing through the second recuperating chamber 502.
Like this, when the refrigerant passes through first backheat chamber 501 and second backheat chamber 502 of regenerator 500, the refrigerant can carry out the heat exchange in regenerator 500, can be with the unnecessary heat transfer in the refrigerant in the first backheat chamber 501 that flows through to the refrigerant in the second backheat chamber 502 to heat recovery in the formation refrigerant not only can let the refrigerant that flows out from the condenser have higher subcooling degree and from evaporating the refrigerant in the refrigerantHair-like deviceThe refrigerant that the ware flows out has higher superheat degree, promotes domestic appliance 1's performance, can utilize moreover to enter into and carry out in the domestic appliance 1 that the unnecessary heat carries out heat recovery and utilizes in the refrigerant that circulates to promote domestic appliance 1's energy utilization efficiency, make domestic appliance 1's use more energy-concerving and environment-protective.
According to the household appliance 1 provided by the embodiment of the invention, the heat regenerator 500 is arranged in the refrigerant cycle, so that the refrigerant can exchange heat when flowing through the heat regenerator 500, the refrigerant flowing out of the condenser has a higher supercooling degree, the refrigerant flowing out of the evaporator has a higher superheat degree, the heat of the refrigerant passing through the heat regenerator 500 can be reasonably utilized, the energy utilization efficiency of the household appliance 1 is improved, the household appliance 1 has a higher use performance, and the use of the household appliance 1 is more environment-friendly.
In some embodiments, as shown in fig. 4, regenerator 500 includes: a casing 510 and a partition 520, the partition 520 being disposed in the casing 510 and dividing an inner chamber of the casing 510 into a first regenerative chamber 501 and a second regenerative chamber 502.
