Abstract

The invention relates to the technical field of air conditioning, in particular to a heating control method of an air conditioner. The invention aims to solve the problems that the frosting speed is high and the user experience is affected when the air conditioner operates in a heating mode in the low-temperature and high-humidity environment. In order to achieve the purpose, the heating control method provided by the invention comprises the steps of determining the condensation temperature of an outdoor environment; obtaining the temperature of an outer coil pipe of an outdoor heat exchanger; comparing the temperature of the outer coil pipe with a first temperature threshold value and the condensation temperature; and when the temperature of the outer coil pipe is smaller than the first temperature threshold value and larger than or equal to the condensation temperature, adjusting the opening degree of a throttling valve according to the temperature interval where the temperature of the outer coil pipe is located. According to the control method provided by the invention, the frosting speed of the outdoor heat exchanger can be delayed, the situation that under the special outdoor environment condition, the opening degree of the throttling valve is controlled only according to the target exhaust temperature, and the throttling valve is smaller when being closed is avoided, the heating capacity curve is ensured to be stable, attenuation is slow, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a heating control method for an air conditioner. Background technique [0002] For air conditioners equipped with electronic expansion valves, in order to achieve better cooling / heating effects, the opening of the electronic expansion valve is usually controlled based on the target discharge temperature of the compressor. When the actual discharge temperature of the compressor When it is lower than the target exhaust temperature, the actual exhaust temperature is increased by controlling the electronic expansion valve to reduce the opening; on the contrary, when the actual exhaust temperature of the compressor is greater than the target exhaust temperature, the electronic expansion valve is controlled to increase the opening to decrease Actual exhaust temperature. [0003] However, when the air conditioner operates in a low-temperature and high-humidity environment, the...
