温湿度独立可控的二管制空调器开发OA

In order to avoid the decrease of air temperature during dehumidification in the existing two-pipe typed air-conditioner,a new two-pipe typed air-conditioner with independent control of air temperature and humidity needs to be developed.In this new two-pipe typed air-conditioner,the indoor heat exchanger is separated into two parts,i.e.,a part of evaporator heat exchanger used for dehumidification and another part of condenser heat exchanger used for heating air.A one-way valve control system is added to control the dehumidification,thus the cooling mode is switched for dehumidification with decreased temperature when the environmental temperature is high,and the heating mode is switched for dehumidification with increased temperature when the environmental temperature is low.The results show that,the optimal area ratio for meeting the target indoor temperature of 25℃and target indoor relative humidity of 50%is 1.0 in the scenarios of summer season,plum rain season and humid season in south China.Under the premise of meeting the same indoor temperature and humidity control,the dehumidification capacity of the new two-pipe typed air-conditioner is 16.6%larger than that of the existing three-pipe typed air-conditioner for the scenario of summer season,and are almost the same with those of the existing three-pipe typed air-conditioner both for the scenario of plum rain season and the scenario of humid season.
