Abstract

The invention discloses an air-conditioner freon-lack protection control method and device. The method comprises the steps that environmental temperature of the outdoor side before starting of an air-conditioner compressor is detected; at least three freon-lack protection judgment conditions are determined according to the environmental temperature of the outdoor side, wherein the freon-lack protection judgment conditions are conditions for controlling an air conditioner to enter a freon-lack protection state; whether the air conditioner enters the freon-lack protection state or not is controlled according to any combination of at least the three freon-lack protection judgment conditions. According to the air-conditioner freon-lack protection control method and device, the technical problem that in the prior art, due to the fact that inner tube temperature is adopted as a judging indicator for freon-lack protection of an air conditioning unit, the accuracy is poor is solved.

Description

technical field [0001] The invention relates to the field of air conditioner detection and control, in particular to a control method and device for fluorine deficiency protection of an air conditioner. Background technique [0002] Along with the raising of social development and living standard, air conditioner is more and more subject to liking of people as a kind of household appliance of indoor temperature regulation. Air conditioners need refrigerant (for example, freon) for both cooling and heating. When the freon of the air conditioner is insufficient, the cooling and heating effects of the air conditioner will be affected. Therefore, it is very important to detect the fluorine deficiency protection of air conditioners. [0003] Existing unit fixed-frequency air conditioners are mainly used to judge the condition of fluorine-deficiency protection based on the temperature difference value of the inner tube or power comparison. In fact, due to cost and other reasons, ...
