Problems solved by technology

However, the speed of the outdoor fan cannot be reduced indefinitely. When the ambient temperature is low to a certain limit, the lowest fan speed cannot meet the cooling function at this temperature, and the following problems often occur: 1. Liquid shock of the compressor; 2. High and low pressure difference of the system 3. If the fun

Abstract

The invention discloses a control method for an air conditioner and the air conditioner. The control method for the air conditioner includes steps that detecting an outdoor environment temperature; when the outdoor environment temperature is smaller than a first preset temperature, controlling the air conditioner to enter a low-temperature refrigerating mode, and controlling the open and close of a stop valve according to the outdoor environment temperature when the air conditioner is located at the low-temperature refrigerating mode. According to the control method for the air conditioner, a compressor is avoided from a liquid impact phenomenon through reducing the heat exchange area of a condenser, and accordingly the normal refrigeration cycle of a refrigerating system is guaranteed, and the low-temperature refrigerating function of the air conditioner is realized.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method and an air conditioner. Background technique [0002] Air conditioners have been widely used all over the world. Generally, when the ambient temperature is high, we use the cooling function of the air conditioner to reduce the indoor temperature, and when the ambient temperature is low, we use the heating function of the air conditioner to increase the indoor temperature. However, in some special environments, such as computer rooms, restaurant kitchens, and homes with fireplaces in extremely cold regions such as North America and Northern Europe, it is often necessary to use the cooling function of the air conditioner at extremely low ambient temperatures. [0003] At present, when the ambient temperature is low, the related technology realizes the cooling function by reducing the rotational speed of the outdoor fan of the air cond...
