Abstract

The invention relates to the technical field of air conditioners, particularly provides a control method for an air conditioner for changing in temperature and aims to solve the problems of drainage failure of an evaporative cold-heat exchanger of an outdoor unit and icing in a water tank and a pipeline communicating with the water tank in low-temperature weather. The control method comprises the following steps of determining a working mode of the air conditioner for changing in temperature, wherein the working mode comprises refrigeration, heating and defrosting; according to the working mode, selectively inputting cooling water on a water pan into a spraying structure or directly discharging the cooling water out of a shell; and starting a compressor of the air conditioner for changing in temperature. After the control method is used, the air conditioner for changing in temperature not only can recycle water in the water pan to provide the cooling water for spraying for the evaporative cold-heat exchanger during refrigeration in summer, but also can timely and directly discharge condensed water or defrosted water in the water pan out of the shell during heating or defrosting in winter, so that the problem of drainage failure caused by icing of accumulated water in the water pan is avoided.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and specifically provides a control method for a heating and cooling air conditioner. Background technique [0002] As we all know, according to different functions, air conditioners can be divided into cooling-only air conditioners, heating-only air conditioners, and heating and cooling air conditioners. As the name implies, single-refrigeration air conditioners only have cooling function and are mainly suitable for heating in northern regions in winter. Single-heating air conditioners only have heating and heating functions and are mostly suitable for southern regions where there is no collective heating in winter. It can be heated and can meet the needs of users in different regions. [0003] The heating and cooling air conditioner includes at least a compressor, an outdoor heat exchanger, an electronic expansion valve, an indoor heat exchanger and a four-way reversing valve. The co...
