Abstract

The invention discloses a double-circulation refrigerating system of an inverter refrigerator and a control method thereof, and relates to the technical field of refrigerators. The system comprises aninverter compressor, wherein an air outlet of the inverter compressor is sequentially connected with an anti-condensation pipe, a condenser, a filter and a one-inlet and two-outlet electric switchingvalve, and an air inlet of the inverter compressor is connected with a two-inlet and one-outlet electric switching valve; the two-inlet and one-outlet electric switching valve and the one-inlet and two-outlet electric switching valve are connected with a refrigerating branch I and a refrigerating branch II; the refrigerating branch I comprises a first capillary tube, a first evaporator and a first liquid accumulator; and the refrigerating branch II comprises a second capillary tube, a second evaporator and a second liquid accumulator. The liquid accumulators are arranged on the two refrigerating branches arranged in parallel respectively, and the two-inlet and one-outlet electric switching valve and the one-inlet and two-outlet electric switching valve are opened and closed, so that migration of refrigerants in two chambers is controlled, and sufficient utilization of the refrigerants is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of refrigerators, and in particular relates to a double-cycle refrigeration system of an inverter refrigerator and a control method thereof. Background technique

[0002] At present, there are series-parallel refrigeration system and pure parallel refrigeration system in the existing double-cycle or multi-cycle refrigeration system refrigerators. When the series-parallel system is used for independent cooling of the compartments with short refrigeration branches, the amount of refrigerant is too much, and the return pipe is prone to appear. The problem of frost dripping, and pure parallel refrigeration system, different refrigeration branches may also have different refrigerant quantities required. When there is too much refrigerant in the refrigeration system, the load on the compressor increases, which affects the life of the compressor. At the same time, in When the cooling of different rooms is switched,...
