Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] This application proposes a refrigerator. The refrigerator includes a refrigerating chamber and a freezing chamber. The refrigerating chamber and the freezing chamber are communicated through an air duct, and the wind in the air duct circulates. When the wind cools down through the evaporator, it is sent into the freezing chamber. , the refrigerant circulates in the evaporator, the refrigerant circulates between the evaporator and the condenser, and a compressor is arranged between the evaporator and the condenser, and the compressor raises the low-pressure r...

Abstract

The invention provides a control method of a refrigerator compressor and a refrigerator. When the compressor is switched on again after being switched off, the operation load of the compressor is determined according to the temperature of the outer side of the refrigerator and the switching-off time of the compressor, the preset heat leakage load q is obtained through calculation according to thetemperature of the outer side of the refrigerator, the actual heat leakage load q<actual> is obtained through calculation according to the switching-off time of the compressor, if q<actual> is largerthan or equal to q, the compressor operates at the preset rotating speed V, and if q<actual> is smaller than q, the compressor operates at the preset rotating speed V and the preset rotating speed increment, wherein the preset rotating speed increment=(q-q<actual>) / compressor energy efficiency ratio cop; and the compressor operating load is increased after it is detected that a door is opened or after defrost operation is carried out. Compared with the prior art, it can be guaranteed that the operation load of the compressor can provide enough refrigerating capacity, meanwhile, the operation frequency of the compressor does not need to be frequently adjusted, and the good energy-saving effect is achieved.

Description

technical field [0001] The invention relates to air treatment equipment, in particular to a method for controlling a refrigerator compressor and a refrigerator. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is a common electrical appliance used for low-temperature preservation of food or other items in daily life. It is widely used in life and industry. At present, the start and stop of the refrigerator compressor is realized through the internal temperature sensor of the refrigerator to sense whether the temperature has reached the start and stop point. In order to determine a reasonable rotational speed, in the prior art, the internal temperature change of the refrigerator is generally measured, and then the rotational speed of the compressor is continuously changed, which will cause the compression rotational speed to fluctuate too frequently, which is not conducive to energy saving. For different tem...
