Claim 3

The heating system of claim 1 further characterized by said means for forcing the cold air through compressors comprising a means for reducing the air pressure on the heated side of the compressors to below the air pressure on the cold side of the compressors.

Claim 4

The heating system of claim 2 further characterized by said means for reducing the air pressure comprising an air handler adapted to receive heated air in said compressor housing and convey the heated air in said compressor housing to another location, said air handler adapted to be selectively operated by a temperature sensing means in the building.

Claim 5

The heating system of claim 3 further characterized by the means for selectively adding supplemental cold make-up air to the cold building air comprising selectively opening louvers in the outside wall of the compressor housing and adapted to allow selectively variable amounts of outside make-up air into the compressor housing.

Claim 6

The heating system of claim 4 further characterized by the means for cooling said compressor housing comprising selectively operable exhaust means on the heated side of said compressor housing, said cooling means being operably connected to a temperature sensing means and adapted to exhaust said heated side of said compressor housing when the temperature therein exceeds a pre-selected level.

Claim 7

The heating system of claim 5 further characterized by said means for selectively adding supplemental heat to the heated air comprising of at least one auxiliary heater situated between the air handler and the building, said auxiliary heater adapted to be selectively operated by a temperature sensing means in the building.

Claim 8

The heating system of claim 6 further characterized by a temperature sensing device located outside the building and adapted to control the rate at which said auxiliary heaters add supplementary heat to the heated air.

Claim 9

The heating system of claim 1 further characterized by the controlling means comprising a plurality of temperature sensing means; one of which is located on the heated side of said compressor housing and adapted to control the means for selectively cooling said compressor housing; another temperature sensing device is located in said building and adapted to control the means for forcing the cold air through the compressors; another temperature sensing device is located in the building and adapted to control the supplemental heater for said heated air; and a temperature sensing device is located on the outside of the building and adapted to control the rate of supplemental heat added to said heated air.

Claim 10

A heating system for buildings containing freezers comprising: A closed compressor room separated from the area to be heated; cold air ducts within the area to be heated adapted to collect cold air in the area to be heated and convey the cold air to a cold side of the compressor room; cold air make-up means operably secured to said compressor room adapted to selectively supplement the cold air from the area to be heated; air handling means secured in proximity to the compressors for selectively forcing the cold air across the compressor coils in the compressor room; supplemental heating means operably secured between the compressor coils and the area to be heated for selectively adding supplemental heat to the compressor coil heated air; hot air ducts connecting the warm air side of said compressor room with the area to be heated; exhaust means operably secured to said compressor room for cooling the warm air side of said compressor room when said warm air side attains a temperature above a preselected level; and, control means operably secured to said system comprising a temperature sensing device in the area to be heated adapted to control said air handling means; another temperature sensing device in the area to be heated adapted to control said supplemental heating means; a temperature sensing device in said compressor room on the warm air side and adapted to control said exhaust means to cool said compressor room; and a temperature sensing device external to the area to be heated adapted to control the rate of supplemental heating.

Claim 11

A heating system for buildings containing freezers comprising: A closed compressor room separated from the area to be heated; cold air ducts within the area to be heated adapted to collect cold air in the area to be heated and convey the cold air to a cold side of the compressor room; cold air make-up means operably secured to said compressor room adapted to selectively supplement the cold air from the area to be heated; air handling means secured in proximity to the compressors for selectively forcing the cold air across the compressor coils in the compressor room; supplemental heating means operably secured between the compressor coils and the area to be heated for selectively adding supplemental heat to the compressor coil heated air; hot air ducts connecting the warm air side of said compressor room with the area to be heated; exhaust means operably secured to said compressor room for cooling the warm air side of said compressor room when said warm air side attains a temperature above a preselected level; and, control means operably secured to said system comprising a temperature sensing device in the area to be heated adapted to control said air handling means; another temperature sensing device in the area to be heated adapted to control said supplemental heating means; a temperature sensing device in said compressor room on the warm air side and adapted to control said exhaust means to cool said compressor room; and a temperature sensing device external to the area to be heated adapted to control the rate of supplemental heating.

Claim 12

The heating system of claim 9 further characterized by said supplemental heating means comprising a plurality of heaters which are employed singly or severally as required by said temperature sensing devices in and outside the building.
