A heating and cooling system incorporates a heat pump that operates conventionally with air drawn from outside the system through its condenser coils that remove heat to the exterior for cooling. In the heating cycle, the condenser motor blower stops and reverses rotation. Outside air is drawn in by the condenser fan, is circulated across the diesel engine and generator, and is blown through the condenser coils outside of the unit. In the heating cycle, a circuit monitors the temperature of the compressor coil and controls the speed of the condenser motor. The heat recovery method of the system maintains power input to heat output ratios in excess of 2:1, even at low outside temperatures. The recovery method also allows the system to operate without defrost cycles. This system may provide auxiliary power, block heat, and battery charging, utilizing a small diesel engine and generator components, and can be installed within a truck, bus, boat, cabin, camper, and the like.

We claim: 1. A system for conditioning the atmosphere of an enclosed space, such as a vehicle, a truck, a boat, or a temporary building, comprising: a power unit, having an engine, an electric generator turned by said engine, a means to transfer heat, and having wiring, outlets, a battery connected
We claim: 1. A system for conditioning the atmosphere of an enclosed space, such as a vehicle, a truck, a boat, or a temporary building, comprising: a power unit, having an engine, an electric generator turned by said engine, a means to transfer heat, and having wiring, outlets, a battery connected to said engine, controls, and a housing; an evaporator unit, having a blower, a motor for said blower, an evaporator coil plumbed to said heat transfer means, and having wiring, a filter ahead of said coil, and a housing encasing said evaporator unit and having a service door; and, one or more electronic circuits connecting said power unit and said evaporator; whereby, said power unit operates said engine to turn said generator thus powering said heat transfer means and said power unit attaches to said enclosed space; whereby, said evaporator unit operates electrically from said generator to add heat to said enclosed space upon said controls calling for heat or to cool said enclosed space upon said controls calling for cooling; whereby, said power unit is less than two feet in length, width, or height and said evaporator unit is less than three feet in length, width, or height; thus, said system cools or heats the atmosphere of an enclosed space independently of the power for the enclosed space; wherein said heat transfer means having a gridwork in communication with the atmosphere, a compressor that compresses a refrigerant, a condenser fan powered by an electric motor, a condenser coil, a reversing valve plumbed with said compressor, and a thermistor sensor controlling the speed of said compressor; whereby for heating said enclosed space, said condenser fan draws air into said power unit, over said compressor and said engine, passing through said condenser coil heating said refrigerant and through said gridwork, and said refrigerant passes through said evaporator coil over which said blower moves air from the enclosed space for heating; and, whereby for cooling said enclosed space, said blower draws air from said enclosed space over said evaporator coil heating a refrigerant then sent to said condenser coil and said condenser fan blows atmospheric air over said condenser coil cooling the refrigerant later compressed in said compressor, and returned to said evaporator unit to cool said enclosed space. 2. The atmosphere conditioning system of claim 1 wherein said heat transfer means is a heat pump and said blower motor reverses direction in coordination with said controls and said heat pump. 3. The atmosphere conditioning system of claim 2 wherein said engine produces at least eight horsepower, said blower produces at least 250 cubic feet per minute air movement, said generator produces at least 3000 watts of electricity in the form of at least 100 volts alternating current and in the form of at least 12 volts direct current, and said compressor operates upon approximately 115 volts alternating current using R-22 refrigerant resulting in at least 10,000 BTU capacity. 4. The atmosphere conditioning system of claim 3 wherein said power unit, provides one or more outlets for operation of auxiliary electrical devices including an engine block heater; electrically connects with the starting system of a vehicle; recharges said battery of said power unit; and, electrically starts said engine. 5. The atmosphere conditioning system of claim 1 wherein said engine is powered by diesel fuel, gasoline, propane, natural gas, or fuel cells. 6. The atmosphere conditioning system of claim 1 wherein said power unit and said evaporator unit are located separately from each other about said enclosed space. 7. The atmosphere conditioning system of claim 1 wherein said power unit and said evaporator unit are located adjacent to each other upon said enclosed space. 8. The atmosphere conditioning system of claim 4 further comprising: a first circuit for controlling said condenser fan, said blower motor, said outlets and said controls including a microprocessor and said thermistor; and, a second circuit for controlling said engine, said evaporator unit, said controls, one or more relays, and said thermistor.
