Abstract
Based upon a prototype heat powered heat-regenerative adsorptive air conditioning system, the effects of step times (heat recovery, mass recovery, and half-cycle) on the coefficient of performance (COP) and specific cooling power (SCP) are studied. The characteristics of real thermodynamic cycles and dynamic SCP are also analyzed. Strong dynamic behavior was found in that the COP and SCP varied with step times. It is found in experiment that a long heat-recovery time usually leads to a lower SCP. But both the COP and SCP can be increased 16% and 6%, respectively, if a very short time—0.5 min of mass recovery is initiated before heat-recovery. The appropriate half-cycle time for the prototype is about 20–25 minutes for which the SCP and COP are excellent.
