Fresh air conditioner, air conditioner control method, control device and readable storage medium

Abstract

The invention discloses an air conditioner control method, the method is applied to a fresh air air conditioner, the fresh air air conditioner includes a fresh air heat exchanger and a first electronic expansion valve, the fresh air heat exchanger is connected in series with the first electronic expansion valve, and the air conditioner The control method includes the following steps: when the fresh air heat exchanger is in dehumidification operation, obtain fresh air temperature and fresh air humidity, and obtain a first temperature of the fresh air heat exchanger; , controlling the first electronic expansion valve to adjust the opening degree. The invention also discloses an air conditioner control device, a fresh air conditioner and a readable storage medium. The invention aims at improving the dehumidification effect while ensuring the heat exchange efficiency of the fresh air heat exchanger.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner control device, a fresh air conditioner and a readable storage medium. Background technique [0002] In order to ensure indoor air quality, most air conditioners are equipped with a fresh air module to ensure the air quality in the indoor environment by introducing fresh air. Among them, in order to reduce the impact of the introduction of fresh air on indoor comfort, some fresh air air conditioners will install a fresh air heat exchanger in the fresh air duct to regulate the temperature and humidity of the fresh air. [0003] Among them, when the fresh air conditioner needs to enter the dehumidification mode, the refrigerant adjustment device corresponding to the fresh air heat exchanger is turned on, and the low-temperature refrigerant flows through the fresh air heat exchanger to absorb heat, so that the moisture i...

Problems solved by technology

However, the refrigerant regulating device is generally opened with a fixed opening, and the flow rate of the refrigerant flowing through the fresh air heat exchanger is not regulated according to the actual situation of the fresh air and the state of the heat exchanger, and it is easy to cause the temperature of the fresh air heat exchanger to be too high or too low , among them, when the temperature is too high, it will reduce the dehumidification effect of the fresh air, and if the temperature is too low, it will easily reduce the reliability of the system operation, affect the heat exchange efficiency of the fresh air heat exchanger, and even reduce the dehumidification effect of the fresh air

It can be seen that the current refrigerant regulation of the fresh air heat exchanger cannot achieve the normal operation of the fresh air heat exchanger while ensuring the dehumidification effect
