Embodiment Construction

[0044] figure 1 It is a schematic side view of the refrigerator 100 according to an embodiment of the present invention. The refrigerator 100 of the embodiment of the present invention generally includes: a box body 110 and a refrigeration system. A storage compartment is defined inside the box body 110 of the refrigerator 100 . The number and structure of storage compartments can be configured as required. E.g, figure 1 The first storage compartment, the second storage compartment, and the third storage compartment are shown in the upper and lower order, wherein the first storage compartment is a door 120 with a rotary opening type, which is arranged on the box body 110. The front surface of the storage compartment is used to close the storage compartment; the second storage compartment and the third storage compartment are provided with the first pull-out storage device 130 and the second pull-out storage device 140, which can be pulled out. It is installed in the storag...

Abstract

The invention provides a refrigerator control method and control device. The refrigerator refrigerating system at least comprises a compressor, a condenser, a drying filter, a capillary pipe and an evaporator which are connected in sequence. The control method comprises the steps of acquiring the environmental temperature of the area where a refrigerator is located; acquiring the temperature of arefrigerant on the inlet side of the drying filter; calculating the temperature difference of the temperature of the refrigerant and the environmental temperature; and adjusting the rotating speed ofthe compressor according to the environmental temperature and temperature difference. Through the refrigerator control method, the pressure of a refrigerator refrigerating cycle system can be adjustedto prevent the problems that the non-refrigerating and poor refrigerating effects are caused when the refrigerator gets close to the heat source, and normal refrigerating cycle of the refrigerator isrealized.

Description

technical field [0001] The present invention relates to the technical field of refrigeration and freezing devices, in particular to a control method and control device of a refrigerator. Background technique [0002] At present, refrigerators on the market mainly control the rotational speed of the compressor by detecting the ambient temperature in which the refrigerator is located. When the side plate of the refrigerator is close to the heat source, the temperature of the refrigerant flowing through the side plate will increase, but because the ambient temperature of the refrigerator does not change significantly, the compressor still runs at a low speed, and the pressure of the system is low, resulting in refrigeration The agent vapor cannot be condensed normally, the refrigeration system is paralyzed, and the refrigerator does not cool down. SUMMARY OF THE INVENTION [0003] An object of the present invention is to provide a refrigerator control method with more precis...
