Abstract
This article presents the performance analysis of the pressurized adsorption chiller, which consists mainly of an evaporator, a condenser and two sorption beds. A total of two specimens of adsorbent/adsorbate pairs, namely Maxsorb III/R134a and Maxsorb III/R410a have been investigated. The evaporator temperature is operated between 5 to 12 °C and the condenser temperature is at ambient temperature, i. e. 30 °C. However, these refrigerants enable sub-zero evaporating temperatures. The R134a adsorbate cooling system is operated at lower pressure ranging from 0.35 to 0.77 MPa, and for R410a adsorbate cooling system, the operating pressure is ranging from 1.45 to 1.89 MPa. This shows R134a is more favorable to use due to its lower operating pressures. In current studies, parametric analysis has been carried out to study the effects of adsorption/desorption time and switching time on the system performance in term of cooling capacity and coefficient of performance.
