Abstract

The invention relates to the field of air conditioner control, in particular to an electric heating structure and an air conditioner compressor starting system and method. The electric heating structure comprises an electric heating control system and an electric heating device. The electric heating control system comprises a driving circuit and an electronic switch circuit. The driving circuit is used for adjusting the duty ratio of the electronic switch circuit. The electronic switch circuit is used for adjusting the output power of the electric heating device according to the duty ratio. The electric heating device is used for preheating an air conditioner compressor. According to the technical scheme, the output power of the electric heating device can be adjusted according to the exhaust temperature of the compressor; compared with the method that preheating is conducted by adopting a constant-power electric heating device in the prior art, the heating speed of the compressor is high, and the preheating process safety can be ensured; and accordingly, the starting waiting time of an air conditioner compressor system under a low-temperature environment is reduced, energy consumption is reduced, and meanwhile, the user experience effect is improved.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to an electric heating structure, an air-conditioning compressor starting system and a method. Background technique [0002] In extremely cold areas, when the outdoor unit of the air conditioner starts to operate, the compressor of the outdoor unit may have a situation where the temperature of the lubricating oil inside the compressor is very low and the viscosity of the lubricating oil is high. When the viscosity of the lubricating oil is high, The lubrication effect is poor, and it is easy to cause rapid wear of the outdoor unit compressor, thereby shortening the service life of the compressor. In addition, due to the influence of the external low temperature environment, the air-conditioning system is likely to cause a liquid hammer accident of the compressor when it is started up, thus causing the compressor to be damaged. The existing technology is to add electric heati...
