Abstract

The invention provides a compressor preheating control method and device, and belongs to the technical field of air conditioners. The method comprises the steps that under the conditions that an air conditioner is in a running state and the bottom temperature of a compressor is larger than or equal to the preset temperature, an outdoor fan is used for wind power generation, and a storage battery is charged; and when the air conditioner is in a heating mode and the temperature of the bottom of the compressor is smaller than the preset temperature, the compressor is preheated through electric energy of the storage battery. When the air conditioner compressor does not need to be preheated, the outdoor fan is used for wind power generation, and the obtained electric energy is stored in the storage battery; and when the compressor needs to be preheated, the compressor is preheated by utilizing the electric energy stored in the storage battery, so that the cyclic utilization of energy is realized, the emission of pollutants is reduced, and meanwhile, the problem that the compressor of the air conditioner is difficult to start in a low-temperature or ultralow-temperature environment for a long time in winter is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular, to a compressor preheating control method and device. Background technique [0002] With the improvement of people's living standards, people's requirements for the quality of life are getting higher and higher. As an important household appliance, air conditioners have entered thousands of households. In daily life, when the air conditioner is working, its outdoor fan will discharge stable wind with a certain intensity of wind speed, but it is not recycled, resulting in a certain waste of resources. [0003] In addition, when the temperature is low, the refrigerating machine oil in the compressor of the air conditioner may solidify, thereby affecting the normal operation of the compressor, and it is very difficult to start the air conditioner, so the compressor needs to be preheated before the air conditioner is started. [0004] In the existing compressor preheating...
