Embodiment Construction

[0013] 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.

[0014] 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 present invention proposes a method for controlling a refrigerator compressor and a refrigerator. When the compressor is turned off and then turned on again, the operating load of the compressor is determined according to the temperature outside the refrigerator and the time when the compressor is turned off, and is calculated according to the temperature outside the refrigerator. Preset thermal leakage load q 标 , the actual heat leakage load q is calculated according to the compressor disconnection time 标 , if q 实 ≥q 标 , the compressor takes preset load q 设 run, if q 实 <q 标 , the compressor takes preset load q 设 + Preset load incremental operation, preset load increment = (q 实 -q 标 ) / compressor energy efficiency ratio cop; increase compressor operating load when door opening is detected or after defrosting operation. Compared with the prior art, the present invention can not only ensure that the operating load of the compressor can provide sufficient cooling capacity, but also does not need to frequently adjust the operating frequency of the compressor, and has a good energy-saving effect.

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...
