Abstract

In this work, the dehumidification and energy performance of a vacuum-based membrane dehumidifier for an air conditioning system were evaluated experimentally. The prototype was tested on the dehumidification characteristic (i.e.,humidity ratio difference, moisture removal rate, and dehumidification effectiveness) and the energy performance (i.e.,coefficient of performance) under various air conditions. The air conditions for evaluating the dehumidification performancewere selected on three parameters: air temperature, air humidity, and air velocity. The experiment results showed that thevacuum-based membrane dehumidifier dried the air without temperature change, and the overall dehumidification performanceof the prototype showed that the humidity ratio difference was range from 3.8 g/kg to 14 g/kg, the moisture removal ratewas range from 0.12 kg/h to 1.0 kg/h, the dehumidification effectiveness was range from 36% to 81%, and the COP wasrange from 0.08 to 0.48 respectively. The parametric analysis showed that the dehumidification performance (i.e., the humidityratio difference and the moisture removal rate) and energy performance was significantly affected by the inlet humidity ratioand the airflow rate. The main effect parameter of dehumidification effectiveness was the airflow rate.
