Abstract

In this study, a transient mathematical model of a 4-bed adsorption chiller using Maxsorb III as the adsorbent and CO₂ as the refrigerant has been analyzed. The performances of the cyclic-steady-state system are presented for different heating and cooling water inlet temperatures. It is found that the desorption pressure has a big influence in the performances due to the low critical point of CO₂ (T_c = 31 C). With 80 kg of Maxsorb III, the CO₂ based adsorption chiller produces 2 kW of cooling power and presents a COP of 0.1, at driving heat source temperature of 95 C along with a cooling temperature of 27 C and at optimum desorption pressure of 79 bar. The present thermal compression air-conditioning system could be driven with solar energy or waste heat from internal combustion engines and therefore is suitable for both residential and mobile air-conditioning applications.
