Abstract

Air conditioning apparatus for a building having an electrical grid operatively connected to receive electricity from a utility is disclosed. The apparatus includes compression refrigeration apparatus with an electric motor connected to drive a compressor, absorption refrigeration apparatus, a cogenerator, an air handler, induction mixing units, a system for circulating air to be conditioned through the air handler and then to said induction mixing units, apparatus for transferring heat from air in the air handler to ice, a heat transfer system connecting the absorption refrigeration apparatus to pump heat to a heat sink from air in the induction mixing units or from air in the air handler, electric circuitry connecting the electric motor of the compression refrigeration apparatus to the building electrical grid for energization, and a heat transfer system for transferring heat generated by the cogenerator into energizing relationship with the absorption refrigeration apparatus. The compression refrigeration apparatus is operable to make ice by pumping heat from water to a heat sink and to store the ice, while the cogenerator is operable to generate electricity and heat. The cogenerator is connected to provide electricity to the electrical grid of the building, and the induction mixing units include a fan for causing a flow of recirculated air from a space to be conditioned, and, when conditioned air is circulated thereto, for delivering to the space a mixture of conditioned air and recirculated air.
