Abstract
Abstract An integrated combined heating and cooling unit comprises a known high efficiency gas fireplace unit stacked on top of a known high efficiency window type air conditioning unit. Novel vent adapters are connected to the rear of the units for connecting them to a source of outside combustion and cooling air to effect high efficiency operations. Novel controls comprise a fireplace relay and an air conditioning relay mounted inside of each of the units. The relays control the on-off operation of the respective units and are actuated by a thermostatic control preferably located remote from the combined units.
