Parametric studies on a desiccant assisted air-conditioner

The desiccant assisted air-conditioners yield lower humidities in the conditioned space compared to the conventional systems. In this paper, the effects of design variables of the air-conditioner, namely supply airflow rate, compressor pumping capacity (compressor speed) and desiccant wheel speed on its performance are studied. It is found that an optimum wheel speed of about 17.5 rph exists at which both moisture removal capacity and COP are maximum.
