Abstract

The invention provides a refrigerant flow adjusting device, a refrigerant circulating system and a refrigerator. The refrigerant flow adjusting device is arranged in the refrigerant circulating system in series and comprises an adjusting cavity, the volume of the adjusting cavity is adjustable, and the refrigerant flow adjusting device is configured to adjust the refrigerant flow in other components of the refrigerant circulating system by changing the volume of the adjusting cavity connected in the refrigerant circulating system in series. According to the refrigerant flow adjusting device, the volume of the adjusting cavity participating in refrigerant circulation is changed, the amount of refrigerant kept in the adjusting cavity in the normal circulating process of the refrigerant is changed, the flow of the refrigerant circulating in an evaporation component is correspondingly changed, the refrigerant in the evaporation component can be kept at the most proper refrigerant flow all the time, the local part in the refrigerant circulating system can reach the optimal refrigerant filling amount, the refrigerant at an outlet of an evaporator has a certain superheat degree all the time, and the power of a compressor and the utilization rate of the heat exchanger area of the evaporator are increased.

Description

technical field [0001] The disclosure belongs to the technical field of refrigerators, and in particular relates to a refrigerant flow regulating device, a refrigerant circulation system and a refrigerator. Background technique [0002] The amount of refrigerant in the refrigeration system of the refrigerator product in the related art needs to be determined through experiments, and the amount of refrigerant injected that matches the lowest point of power is usually used. In order to ensure that the refrigerant in the refrigeration system can be fully utilized, the outlet of the evaporator must have a certain degree of superheat. At this time, the effective heat transfer rate of the refrigerant in the evaporator is relatively high. [0003] For multi-system refrigerators with two or more compartments with independent temperature control, the optimal refrigerant charge is generally the refrigerant charge that matches the minimum power of the system in the fully open mode of t...
