Problems solved by technology

[0003] When the refrigerating room returns to the weathering defrosting method or the electric heating defrosting method independent of the freezing room, since the refrigerating room has a separate evaporator for cooling, the air duct is independent of the freezing room, so that the refrigerating evaporator defrosts the refrigerator during defrosting. The influence of temperature is very weak, but it has a great influence on the fluctuation of the freezer, and the cooling of the two compartments is obviously out of sync during the recovery period after defrosting, the recovery period takes a long time, and the energy consumption increases

Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] figure 1 It is a diagram of a fully parallel double-circulation system commonly used in refrigerators at present. When the compressor is running, the refrigerating evaporator or freezing evaporator is switched through the electronic three-way valve to complete the system to supply cooling to the refrigerating room or freezing room.

[0034] Such as figure 2 As shown, the embodiment of the present invention provides a dual-system refrigerator control method, including the following steps:

[0035] S0, before the start of the defrosting process, when the operation of the refrigerator meets the defrosting start conditions, close the electronic three-way valve, keep the compressor running for t0, and then exec...

Abstract

The invention relates to the technical field of refrigerators, in particular to a control method and system for a dual system refrigerator and the dual system refrigerator. The control method for the dual system refrigerator comprises the steps that after the defrosting process is completed, high-frequency operation freezing time control is conducted firstly, and then low-frequency operation temperature control is conducted. According to the control method for the dual system refrigerator, the defrosting recovery phase duration can be shortened, power consumption in the recovery phase can be reduced, and the refrigerating and freezing modes are rapidly recovered to the normal and stable operation states.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dual-system refrigerator control method, a system and a dual-system refrigerator. Background technique [0002] figure 1 It is a diagram of a fully parallel double-circulation system commonly used in refrigerators at present. There are two evaporators and corresponding supporting fans in this system, the refrigerating and freezing chambers are independent of each other, and the defrosting process can also be independent of each other. The refrigerated evaporator of the double-cycle refrigerator can be defrosted by return weathering, or it can be defrosted by electric heating like the refrigerated evaporator. During the defrosting process of the refrigerated evaporator, since the heating tube is as high as 200°C, a large amount of hot air will flow into the refrigerator compartment through the air duct during this period, which will significantly increase the freezing ro...
