Abstract

The invention discloses a compressor. The compressor comprises a compressor cylinder and an oil tank located at the bottom of the cylinder. The cylinder is further provided with an exhaust pipe and an air return pipe. A heating device and a temperature sensor are arranged at the bottom of the oil tank. Pressure sensors are arranged on the exhaust pipe and / or the air return pipe. The oil tank temperature detected by the temperature sensor and the refrigerant pressure detected by the pressure sensor are used for determining whether the heating device works or not. The invention further discloses a heating control method of the compressor oil tank and an air conditioning system. By the compressor, the air conditioning system and the heating control method, the refrigerant capacity in lubricating oil in the oil tank can be effectively controlled, and the lubricating effect of the lubricating oil can be increased.

Description

technical field [0001] The invention relates to the field of compressor control, in particular to a heating control method for an oil pool of a compressor, a compressor, and an air-conditioning system. Background technique [0002] In most air conditioners, there is generally an electric heating belt for the compressor to heat the oil pool at the bottom of the compressor to prevent a large amount of refrigerant from dissolving in the oil pool and diluting the lubricating oil, thereby affecting the lubrication effect. [0003] The current control method for the electric heating belt of the compressor generally controls the electric heating belt in reverse according to the start and stop of the compressor, that is, the heating belt is turned on when the compressor is powered off, and the electric heating belt is stopped when the compressor is turned on. However, practice has proved that this control method cannot accurately control the amount of refrigerant dissolved in the lu...
