Abstract

The invention discloses a comfortable refrigeration control method of a variable frequency air conditioner. The comfortable refrigeration control method of the variable frequency air conditioner comprises the process of executing coiler temperature PID control. The process of executing the coiler temperature PID control comprises the steps that the indoor environment temperature and the real-time set temperature of the air conditioner are obtained, and the real-time indoor environment temperature is compared with a known first temperature threshold value; if the real-time indoor environment temperature is higher than the first temperature threshold value, a target coiler temperature is determined according to real-time indoor environment temperature and used as the real-time target coiler temperature; if the real-time indoor environment temperature is not higher than the first temperature threshold value, the target coiler temperature is determined according to the real-time set temperature of the air conditioner and used as the real-time target coiler temperature; and the real-time coiler temperature of an evaporator is obtained, and coiler temperature PID control is executed based on the real-time coiler temperature and the real-time target coiler temperature. By the adoption of the comfortable refrigeration control method of the variable frequency air conditioner, the comfort demands of different users can be met.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method for an inverter air conditioner, and more specifically, relates to a comfortable cooling control method for an inverter air conditioner. Background technique [0002] In the hot summer, many people cannot do without the air conditioner at night. Turning on the air conditioner while sleeping at night, while covering with a thick quilt, will cause a waste of energy, and secondly, accidentally kicking off the quilt will easily cause a cold, and cold air will inhale from the respiratory tract, which will make people feel dry and sore throat. In recent years, people's health awareness has become stronger and their knowledge more and more abundant. The needs for comfort and health are equally important. On the one hand, they do not want the cold to invade the body; However, the function of the current air conditioner makes most of the users use th...
