Abstract

The invention provides a control method for preventing a compressor from starting with liquid. The control method comprises the following steps of acquiring environment temperature and bottom temperature of the compressor; determining a temperature difference change rate according to the environment temperature and the bottom temperature; and determining whether an electric heating tape of the compressor is started or not according to the temperature difference change rate. The control method for preventing the compressor from starting with the liquid solves the technical problem that a methodfor preventing the compressor from starting with the liquid in the prior art is large in energy consumption, so that the starting and stopping of the electric heating tape of the compressor can be reasonably regulated and controlled, and the technical effect that the energy consumption is reduced while the compressor is prevented from starting with the liquid is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular, to a control method for preventing a compressor from starting with liquid. Background technique [0002] When the air-conditioning unit is shut down for a long time, the material made of the compressor is not sensitive to the temperature change of the outdoor environment, and the temperature change inside the compressor is relatively slow. Therefore, when the outdoor ambient temperature rises rapidly, the overall temperature response of the compressor is slow, resulting in high outdoor ambient temperature and low compressor temperature, resulting in a low pressure inside the compressor, and the refrigerant flows from the two devices to the compressor. Liquid accumulates at the bottom of the compressor, causing the compressor to start with liquid, and the frequent start of the compressor with liquid directly affects the reliability of the compressor. [0003] At presen...
