Coating layer having a conforming material for a compressor and method of using the same

A heating, ventilation, air conditioning, and refrigeration (HVACR) system, comprising:

• a compressor;
• a condenser;
• an expander;
• and an evaporator,
• wherein the compressor comprises:
• a compressor housing;
• a rotating component disposed within the compressor housing, wherein the rotating component and at least one second component form a compression chamber to compress a working fluid;
• each of the rotating component and the at least one second component having a mating surface, the mating surface of the rotating component and the mating surface of the at least one second component defining a meshing location between the rotating component and the at least one second component to form the compression chamber;
• a coating layer provided on the mating surface of at least one of the rotating component or the at least one second component, wherein the coating layer comprises at least a first applied layer and a second applied layer, wherein the first applied layer and the second applied layer are separate layers and both the first applied layer and the second applied layer include a conforming material, wherein the conforming material in the first applied layer has a different particle size than the conforming material in the second applied layer such that a combination of the first applied layer and the second applied layer seal the mating surface.

A method of manufacturing a positive displacement compressor with a conforming material on at least one contacting surface, comprising:

• providing at least one rotating component or a second component that forms a compression chamber in a compressor housing for the positive displacement compressor, each of the rotating component or second component having a contacting surface, the contacting surface of the rotating component and the contacting surface of the second component defining a meshing location between the rotating component and the second component to form the compression chamber;
• coating a first coating layer on the contacting surface of at least one of the rotating component or the second component;
• coating a second coating layer on the contacting surface of the at least one of the rotating component or the second component, wherein both the first coating layer and the second coating layer include a conforming material, wherein the conforming material in the first coating layer has a different particle size than the conforming material in the second coating layer;
• and
• forming the compressor housing including the rotating component and the second component within the compressor housing, wherein the at least one rotating component or the second component that form the compression chamber includes the first coating layer and the second coating layer such that a combination of the first coating layer and the second coating layer seal the contacting surface,
• wherein the first coating layer and the second coating layer are separate layers.
