Abstract

The invention provides a method for improving the heating and cooling effect of an air-conditioner. According to the method, the optimal refrigerant flow of each indoor unit is obtained through the detection of the relationship between refrigerant flow values and the indoor temperature and the coiler temperature and the adjustment of the opening degree of an electronic expansion valve, mistaken adjustment occurring when the evaporating temperature is changed significantly is avoided, and meanwhile, the specific flow of each indoor unit can be learned. Due to the fact that the refrigerant flow of corresponding indoor units is optimal, energy is saved, and the heating and cooling effect is good.

Description

technical field [0001] The invention relates to a method for improving the heating and cooling effect of an air conditioner, in particular to a method for improving the cooling and heating air conditioning system of multiple indoor unit units. Background technique [0002] As refrigeration or heating equipment, air conditioners have become a part of people’s lives, improving the comfort of people’s lives. However, the refrigerant in the air conditioner is fixed. If there is deviation or accumulation during flow, it will consume more power and cannot achieve the desired effect. [0003] At present, the multi-connected air conditioners on the market adopt a new technical solution to prevent the refrigerant from drifting when cooling and heating, so as to improve the cooling and heating effect of the system. [0004] For example, the patent number is: CN201110255060.4, and the patent name is: Control method for preventing refrigerant bias flow when multi-connected air conditio...
