A vehicle climate control system operable in a winter mode and a summer mode includes an engine-exhaust-driven hot heat transfer fluid (HTF) circuit coupled with a heater core during the winter mode to provide passenger cabin heating, and thermal energy stored in a standalone hot phase change material (PCM) battery in the hot HTF circuit may provide surge heating at or prior to engine start. The hot HTF circuit and a cold HTF circuit including an HTF cooler drive two adsorbers in the summer mode, thereby providing passenger cabin cooling in conjunction with a refrigerant circuit which includes a condenser, evaporator, expansion valve, and standalone cold PCM battery. Thermal energy stored in the standalone cold PCM battery may provide surge cooling at or prior to engine start.
