Temperature-fixing dehumidifying air conditioner and control method thereof

Abstract

This invention is a temperature fixed dehumidifying air conditioner and its controlling method. The said air conditioner system includes compressor, electromagnetic four-way reversing valve, outdoor heat exchanger, filter, throttling electron expansion valve and indoor heat exchanger. The said indoor heat exchanger is divided into dehumidifying section and heating section by the dehumidifying electromagnetic valve. In order to fulfill intelligent control, the air conditioner system is arranged with several temperature and humidity sensors. This invention has separated dehumidifying function. It will not influence the cooling and heating capability when dehumidifying. This invention can also set the needed temperature and humidity by controlling the throttling electron expansion valve, dehumidifying electromagnetic valve, outdoor fan rotating rate and compressor running frequency. It gives the users a pleasure indoor environment.

Description

technical field [0001] The present invention relates to a dehumidifying air conditioner, more specifically to a constant temperature dehumidification air conditioner and its control method, which can set the required temperature and humidity during dehumidification operation, and realize cooling dehumidification and constant temperature dehumidification through intelligent control and dehumidification. Background technique [0002] Existing room air conditioners have a dehumidification function, but there is no essential difference between this kind of dehumidification and cooling. It is only realized by controlling the indoor fan to operate at a slightly lower wind speed than the cooling operation or intermittently according to the temperature of the room. The temperature of the room cannot be controlled during the dehumidification operation. The air supply temperature of the air conditioner is low, which will bring about a drop in the room temperature while dehumidifying. ...

Problems solved by technology

[0004] However, the above-mentioned air conditioner performs dehumidification operation, simply operates the dehumidification operation mode without cooling down, does not take into account the difference between the set temperature and the indoor temperature, the difference between the set humidity setting and the indoor humidity, and cannot separately control the temperature and humidity of the room. Optimizing the operating modes of outdoor fans and compressors
