Hydraulic compression will cause damage to the compressor and affect the life of the compressor
[0003] At present, the electric heating belt of the compressor will always be turned on after being powered on, or it will continue to be turned on after the ambient temperature is lower than a threshold, which consumes a lot of standby power, which is not conducive to energy saving and consumption reduction.

Embodiment Construction
[0030] For air conditioners, when the compressor is not working, the refrigerant needs to be heated to ensure that the refrigerant can fully evaporate. The power of the compressor electric heating belt is between a dozen watts and tens of watts. In the standby state, the power consumption of the compressor electric heating belt is the largest energy consumption of the air conditioner. The invention can reduce the power consumption of the electric heating belt of the compressor under the condition of ensuring the heating effect of the electric heating belt, so as to achieve the purpose of saving energy and electricity.
[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] The first embodiment of the present invention provides a method for controlling the electric heating belt of a co...

The invention provides a control method, control system and air conditioner for a compressor electric heating belt. The control method includes: when the compressor is turned off, detecting the ambient temperature; when the ambient temperature is not greater than a first threshold, detecting the compressor discharge Air temperature and condenser coil temperature; control the operating state of the electric heating belt according to the compressor discharge temperature and the condenser coil temperature. Control the operating state of the electric heating belt according to the relationship between the compressor discharge temperature and the condenser coil temperature, instead of continuously turning on the electric heating belt, which can save energy consumption.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method, a control system and an air conditioner for a compressor electric heating belt. Background technique [0002] An air conditioner includes an indoor unit and an outdoor unit. Wherein the outdoor unit is provided with a compressor, the compressor is filled with refrigerant, and an electric heater is arranged on the outer wall of the compressor, and the electric heater is used for heating the refrigerant in the compressor. When the outdoor ambient temperature is high, the liquid refrigerant in the compressor can generally be fully evaporated to ensure the normal operation of the compressor. But when the outdoor ambient temperature is low, the liquid refrigerant in the compressor is not easy to fully evaporate. When the compressor starts, if the liquid refrigerant is not fully evaporated, a liquid compression occurs. Hydraulic compression will cause dama...
