I-type double-circulation refrigeration control method for variable-frequency refrigerator

Abstract

The invention provides an I-type double-circulation refrigeration control method for a variable-frequency refrigerator. A double-circulation refrigeration system of the variable-frequency refrigerator is subjected to refrigeration control through a single-chamber refrigeration operation module and a double-chamber double-circulation operation module; the double-circulation refrigeration system of the variable-frequency refrigerator comprises a variable-frequency compressor, a dew removal pipe, a condenser, a filter, an air return pipe, a liquid storage device, an electromagnetic valve, two refrigeration branches, a controller and two refrigeration chambers; each of the two refrigeration branches comprises a capillary tube and an evaporator, and the two evaporators are respectively arranged in the two refrigeration chambers; when only one refrigeration chamber has the refrigeration requirement, the single-chamber refrigeration operation module is operated; and when the two refrigeration chambers both have refrigeration requirements, the double-chamber double-circulation operation module is operated. Balanced cooling of the two refrigeration chambers can be effectively guaranteed, the condition that one certain refrigeration chamber is too cold or too hot is avoided, and the method is more suitable for two refrigeration chambers with similar capacity, temperature and size, such as wine cabinets and cigar cabinets and other products with high precision requirements.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to an I-type double-cycle refrigeration control method for an inverter refrigerator. Background technique [0002] The Chinese patent with application number 201120234469.3 discloses a dual-temperature-controlled refrigerator. Its refrigeration system includes a compressor, a condenser, a throttling device, a refrigeration evaporator, and a freezing evaporator. Located in the freezer, the outlet of the compressor, the condenser, the throttling device, the freezer evaporator, the freezer evaporator and the inlet of the compressor are connected sequentially through pipelines, a freezer thermostat is placed in the freezer room; a freezer thermostat Placed in the freezing chamber, the refrigerating thermostat and the freezing thermostat are electrically connected to the compressor through a transfer switch. This kind of refrigerator uses the temperature of the refrigerator or fre...

AI Technical Summary

Problems solved by technology

This kind of refrigerator uses the temperature of the refrigerator or freezer to control the operation of the compressor, so that the refrigerator can work under two different temperature control ranges. For refrigeration, it is difficult to selectively control the cooling operation of the refrigerating evaporator and the freezing evaporator according to the cooling needs of the refrigerating room and the freezing room, which has the disadvantages of large energy consumption and poor cooling effect, so it is necessary to improve
