Study on two stage activated carbon/HFC-1340 based adsorption chiller
In this paper, a theoritical analysis of a thermally driven two-stage four-bed adsorption chiller utilizing low-grade waste heat of temperatures between 50 deg C and 70 deg C in combination with a heat sink (cooling water) of 30 deg C for air-conditioning application has been described. Activated ca...
