Abstract

In this study, the dynamic behaviour of a 4 bed adsorption chiller was analysed employing silica gel as the adsorbent and water as the refrigerant. The simulated results in terms of heat transfer fluid temperatures cycle average cooling capacity and coefficient of performance (COP) were obtained numerically. With 47 kg of silica gel, the system is able to produce 14 kW of cooling power and 0.46 of COP at driving heat source temperature of 85ºC which can be obtained from waste heat or solar energy. In particular, it can be powered by the waste heat from the internal combustion engine and therefore is suitable for automobile air-conditioning applications. Water is used as refrigerant as it has no harm to environment, it is a non-toxic substance, moreover, ethanol has comparatively higher vapour pressure even at low temperature. This innovative system utilizes effectively low-temperature waste heat sources of temperature between 60 and 95ºC along with a coolant at 30ºC.
