Problems solved by technology

[0005] In the prior art, only the electric heating belt is controlled, and the heating belt is turned on through the output signal, but the working state of the electric heating belt is not fed back. As a result, once there is an output signal but the actual electric heating belt is not turned on, if the compressor is normal at this time Turning on the machine will cause the compressor to wear and tear, or it may cause the compressor to fail to start or cause an alarm, resulting in irreversible losses

Abstract

The invention discloses an air conditioner. The air conditioner comprises a compressor, an electric heating belt, a detection unit, a judging unit and a control unit, wherein the electric heating belt is used for heating the refrigerant oil in the compressor; the detection unit is used for detecting parameters representing the working state of the electric heating belt; the judging unit is used for judging whether the parameters meet preset conditions or not; and the control unit is connected with the electric heating belt, the judging unit and the compressor, and the control unit is configured to control the compressor to be started when the judging unit judges that the parameters meet the preset conditions and the compressor is not started. By feeding back the working state of the electric heating belt, normal starting of the air conditioner compressor is guaranteed, and the starting reliability of the compressor of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to air conditioners. Background technique [0002] In the air conditioning system, the compressor is like the power unit of the air conditioner, and the viscosity of the refrigeration oil plays a vital role in the reliability of the compressor. In a low-temperature environment, according to the characteristics of the refrigerant, if the air conditioner has not been used for a long time, the temperature and pressure in the compressor cavity will be low, and due to gravity and the attraction of the refrigerant oil in the compressor, the refrigerant will migrate to a place with a lower temperature. The lower the temperature, the greater the migration, and the liquid refrigerant will accumulate in the compressor crankcase. [0003] In addition, due to the miscibility of the compressor refrigeration oil and the refrigerant, a large amount of refrigerant migration will cause the...
