Design and measurement of the non-cooling dehumidification room air-conditioners

The novel appliance could shift between cooling mode and non-cooling dehumidification mode through valve switching, avoiding the invest for installing a dehumidifier. Based on the orthogonal test, studies the dehumidification capacity, EER, and energy consumption, and presents the fitting equations. The results show that the dehumidification capacity ranges from 1 to 3 kg/h, which could meet the dehumidification demand of an average residential house. The dehumidification EER range is 1~2, and proper assessment of this process should be studied. The outlet temperature of the unit is 1~2.5 ℃ lower than the inlet temperature, so the unit could be further studied to get a better result.
