Abstract

The invention relates to the field of air conditioner control, in particular to a preheating structure, preheating system and preheating method for a compressor and an air conditioner. The method includes the following steps that after the compressor is started, the gas return temperature at the position of a gas return opening of the compressor is collected; and the gas return temperature is compared with the preset normal lubricating oil temperature, and opening or closing of a first electronic valve, a second electronic valve and a third electronic valve is controlled according to the comparison result. Compared with a former electrical-heating preheating manner, the temperature rising speed is high, the low-speed operation time of the system compressor can be shortened, the compressor can rapidly accelerate to be in the normal operation state, the heating capacity is rapidly improved, and the user experience effect is improved.

Description

technical field [0001] The invention relates to the field of air conditioning control, in particular to a compressor preheating structure, a preheating system, a preheating method and an air conditioner. Background technique [0002] In extremely cold areas, when the outdoor unit of the air conditioner is used to start running, the temperature of the lubricating oil inside the compressor of the outdoor unit may be very low, and the viscosity of the lubricating oil is high and the lubrication effect is poor, causing the outdoor unit compressor to run quickly. Wear and tear, ultimately leading to a shortened compressor life. The existing technology is to use an external electric heating belt, but because the outside of the compressor is generally wrapped with thick sound insulation cotton, a high-power electric heating belt is likely to cause the sound insulation cotton to catch fire, and a low-power electric heating belt will cause the entire preheating The process time is t...
