A high efficiency air conditioning system combining a desiccant assisted air conditioner with a heat pump device in which quick start-up of the system under all conditions by selecting a start-up mode operation is disclosed. The desiccant assisted air conditioning system comprises a recovery heat exchanger for recovering heat from the regeneration air flowing downstream of the desiccant device in the regeneration passage into the refrigerant flowing in the heat pump cycle passage for use as heat of evaporation in the heat pump device.
