Temperature-fixing dehumidifying air conditioner control method

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.
