Abstract

Abstract A refrigeration or air conditioning system or unit is provided that includes revolving or oscillating heat exchangers, wherein the heat exchanger on the refrigeration side acts as an evaporator, while the other acts as a condenser on the outside. On a predetermined schedule the heat exchangers are rotated or oscillated 180° so as to bring or move the frost laden evaporator outside and a clean condenser inside. Suitable controls are provided for selectively reversing the cycle at the proper time or interval.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 191 words
In refrigeration, air conditioning systems and the like, a wall having an opening therein, said wall having on opposite sides thereof an outside area and an inside area, a support surface, a rotary unit above said support surface and said rotary unit including a housing movably mounted in the opening in said wall, seal flaps contiguous to said unit, said housing including a pair of similar heat exchangers that selectively provide and define a condenser and an evaporator, said housing having a flat bottom wall spaced from said support surface, and said bottom wall including spaced apart air inlets that are arranged at the lower portion of said heat exchangers, said housing further including a curved side wall that has diammetrically opposed air outlets therein, a cover detachably mounted on said housing, each of said heat exchangers including coils and headers and motor operated fans, said housing including an intermediate section defined by spaced parallel wall portions, a compressor mounted in said intermediate section, conduits operatively connecting said compressor and heat exchangers together, solenoid valves and expansion valves operatively connected to said conduits, and means for oscillating and moving said unit.
Claim 2
Dependent Claim 191 words
In refrigeration, air conditioning systems and the like, a wall having an opening therein, said wall having on opposite sides thereof an outside area and an inside area, a support surface, a rotary unit above said support surface and said rotary unit including a housing movably mounted in the opening in said wall, seal flaps contiguous to said unit, said housing including a pair of similar heat exchangers that selectively provide and define a condenser and an evaporator, said housing having a flat bottom wall spaced from said support surface, and said bottom wall including spaced apart air inlets that are arranged at the lower portion of said heat exchangers, said housing further including a curved side wall that has diammetrically opposed air outlets therein, a cover detachably mounted on said housing, each of said heat exchangers including coils and headers and motor operated fans, said housing including an intermediate section defined by spaced parallel wall portions, a compressor mounted in said intermediate section, conduits operatively connecting said compressor and heat exchangers together, solenoid valves and expansion valves operatively connected to said conduits, and means for oscillating and moving said unit.
Claim 3
Dependent Claim 46 words
The structure as defined in claim 1 wherein said last named means comprises a hollow shaft operatively connected to said housing, and a motor operatively connected to said shaft for turning said shaft to move said housing whereby the evaporator and condenser selectively assume interchangeable positions.
