US Patent:

40095860, Mar 1, 1977

Filed:

Feb 3, 1975

Appl. No.:

5/546768

Inventors:

John A. Skvarenina - Chicago IL

International Classification:

F25D 2112

US Classification:

62 80

Abstract:

The embodiment of the invention disclosed herein is directed to a new and improved method and apparatus for preventing condensation from forming about refrigerator and freezer doors. Warm air produced by the compressor of a refrigerator or freezer unit is channeled either directly or indirectly therefrom to flow vertically along the peripheral sealed edges of the freezer door to prevent condensation from developing therealong. The heated air from the compressor is directed through a vent or outlet port formed in a kick plate or through outlets formed in the housing at a location near the bottom vertical edges of the door. This will provide vertical columns of warm air to flow therealong and prevent condensation.

Abstract:

The embodiment of the invention disclosed herein is directed to a rotary compressor and/or condenser for refrigerating systems. The rotary compressor has a rotor with a passage formed therethrough to be in fluid communication with an inlet port at one end of the rotor housing and in periodic fluid communication with an outlet formed at the other end of the rotor housing. The outlet passage is formed in a valve plate which is in sliding sealing contact with the terminating end of the rotor of the compressor. A condenser may be connected to a common shaft with the compressor rotor and has a rotating member with a helical passage extending therethrough. Heat radiating fins are formed on the condenser rotor to improve heat transfer for cooling.
