An integrated air conditioning and hot water supply system for conditioning air and supplying hot water to a building is described. The system incorporates a hot water tank in the system which feeds a heat exchanger to heat air which is recirculated from the building when required during cool weather periods. A combined air dehumidification device and cooling device are also provided to dehumidify and cool return air from the building in a recirculation circuit when required by the building during warm weather periods. The cooling devices incorporate coils connected to the city water supply whereby to preheat a supply of water to the hot water tank. The combined circuit also cools fresh air and treats it to provide a source of heated air to regenerate a desiccant wheel which is used as the dehumidification device. A heat recovery ventilator is also incorporated in the integrated system to treat exhaust air from the building during cool weather periods and to admit warmed fresh air thereto.
