Experimental study on adiabatic pre-cooling systems for air cooled condensers in hot and humid climates.

ABSTRACT: The rise in ambient temperature caused by heat waves has led to increased demand for comfort cooling that affects the operational reliability of unitary air conditioning system. This study investigates the performance of a residential air conditioning unit of 1 ton equivalent by integrating adiabatic pre-cooling systems into the air-cooled condenser in the hot and humid climate of the Chennai region. Three types of adiabatic pre-cooling methods were employed: (1) evaporative cooling (EC) pad, utilising a 100 mm-thick cellulose pad; (2) mist cooling, achieved through an ultrasonic humidifier; and (3) a combination of EC pad and mist cooling, using a reduced cellulose pad thickness of 50 mm. The study assessed energy consumption, operational performance, condensate water production, condense
