An auxiliary active heating and air conditioning system which uses a fuel fired heater as an energy source for both heating and air conditioning a passenger area of a motor vehicle. The system also utilizes a single heat exchanger to supply both heated and cooled air to the passenger area. The system includes a fuel fired heater for heating heat transfer fluid and a two bed sorber cooling system. The system being operable in a heating mode and a cooling mode. In the heating mode, the heated heat transfer fluid from the fuel fired heater is directed to heat exchanger in order to heat the passenger compartment. In the cooling mode, the heat transfer fluid from the heater is alternately directed to the two sorber beds such that one sorber bed is heated while the other bed cools. The alternate heating and cooling of the sorber beds in the cooling mode causes the sorber cooling system to operate and thereby deliver cooled heat transfer fluid to the heat exchanger in the passenger area.
