IIR documentSummary
Evaporative condenser is an energy efficient and environmentally friendly air conditioning equipment. This paper proposed an air conditioning system using dual independent evaporative condenser and investigated the cooling performance. Many factors, such as evaporator water inlet temperature, compressor frequency, air dry-bulb temperature, air velocity and water spray rate, which influenced the cooling performances of air conditioning system with evaporative condenser have been investigated. The results indicated that cooling capacity and coefficient of performance (COP) increased significantly with the increasing of evaporator water inlet temperature (12–25°C), the air velocity (2.05–3.97 m s-1) and the water spray rate (0.03–0.05 kg m-1 s). However, COP decreased with the increasing ambient air dry-bulb temperature (31.2–35.1°C) and the compressor frequency (50–90 Hz). Furthermore, the heat transfer coefficient (K0) was 232–409 W m-2 K-1 in different air velocity and water spray rate.
