CPC classification number: B60H1/3205 ,  B60H1/005 ,  B60H1/322 ,  B60H1/32281 ,  B60H2001/3266

Abstract: An air-conditioning system including a primary circuit and a secondary circuit is provided. The primary circuit includes a flow of refrigerant, an evaporator and a chiller configured to exchange heat between a coolant and the refrigerant. The secondary circuit includes a heat exchanger in fluid communication with the chiller to receive the coolant. The heat exchanger includes a phase change material in heat exchange relationship with the coolant, such that the coolant exchanges heat with the phase change material to store thermal energy in the phase change material. The air-conditioning system is implemented in a machine in which during an idle-off state, the stored energy in the heat exchanger is discharged to provide an air-conditioning effect.
