Experimental performance of adsorption chiller with fin and tube heat exchanger

Adsorption chiller is one of the solution related to environmental issues caused by conventional cooling system. This paper presents an experimental performance of adsorption chiller with fin and tube heat exchanger in Mechanical Engineering, Universitas Indonesia. The chiller design configuration is composed of two sorption chambers, each has compact fin tube heat exchangers as adsorber, condenser, and evaporator. The chiller is tested under typical condition for hot water inlet/cooling water inlet/chilled water outlet temperatures are 64.4/31/8.9°C, respectively. Heat and mass recovery was adopted in experiment to increase the cooling power. The cooling time was varied to obtain the heat recovery optimum time related to the performance. Average value of COP and cooling power were obtained 0.77 and 3.2 kW, respectively, at adsorption/mass recovery/heat recovery time 600/40/20.
