Attorney, Agent or Firm:

A heating and cooling system utilizing solid waste for selectively heating and cooling a confined area. The heating and cooling system comprises a pyrolytic incinerator which is capable of combusting the solid waste in an oxygen lean atmosphere. A fan is used to supply outside air to the pyrolytic incinerator to support combustion therein. The fan is also used to exhaust the flue gases through an exhaust system. An afterburner is located in the exhaust duct of the incinerator to allow further combustion of waste gases which have become mixed with the outside air during combustion of the solid waste. A heat exchanger is located in the exhaust duct downstream of the afterburner and transfers the heat of the outside air and waste gas combustion products to heating water passing through the heat exchanger. The heating system portion of the heating and cooling system has a first closed loop piping system selectively connected to the heat exchanger for circulation of the heated water through a radiator in the confined area. Also included is a device for automatically feeding solid waste into the pyrolytic incinerator. The cooling system portion includes a second closed loop piping system which is selectively connected to the heat exchanger and which circulates water through an absorption cold generator. A third closed loop piping system is used to circulate cold water from the absorption cold generator through air conditioners in the confined area to cool air passing therethrough. The absorption cold generator uses the heated water of the second closed loop piping system to produce cooled water for the third closed loop piping system.

DETAILED DESCRIPTION I claim: 1.
A heating and cooling system utilizing solid waste for selectively heating and cooling a confined area, said heating and cooling system comprising: a pyrolytic incinerator capable of combusting said solid waste, means for supplying outside air to said pyrolytic incinerator to support combustion of said solid waste in a low oxygen atmosphere and for exhausting through an exhaust duct of said pyrolytic incinerator after said combustion of said solid waste; an afterburner in said exhaust duct of said pyrolytic incinerator capable of combusting waste gases which have become mixed with said outside air during combustion of said solid waste to further heat said outside air and waste gas combustion products; a heat exchanger in said exhaust duct downstream of said afterburner capable of transferring heat of said outside air and said waste gas combustion products to heating water passing through said heat exchanger; a heating system portion including a first closed loop piping system selectively connected to said heat exchanger and capable of circulating said heated water of said heat exchanger through a radiator in said confined area to transfer the heat contained in said heated water to air passing through said radiator; means for feeding said solid waste into said pyrolytic incinerator; a cooling system portion including a second closed loop piping system selectively connected to said heat exchanger and capable of circulating said heated water of said heat exchanger through an absorption cold generator; a third closed loop piping system connected to said absorption cold generator including means for circulating cooling water therethrough to supply an air conditioner in said confined area to cool air passing through said air conditioner; and said absorption cold generator capable of employing heat from said heated water of said second closed loop piping system to cool said cooling water of said third closed loop piping system; whereby said confined area is heated when said second closed loop piping system is isolated from said heat exchanger and is cooled when said first closed loop piping system is isolated from said heat exchanger
