Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The invention relates to an apparatus and method for providing refrigerant flow to a plurality of remote evaporators utilizing a single or centralized compressor station and a centralized condenser or condenser station.

[0003] 2. Description Of The Related Art

[0004] In the past, various systems have been proposed for arranging an air conditioning system having a centralized compressor and / or centralized condenser station.

[0005] However, all prior art proposals were severely curtailed in their application, due primarily to a refrigerant piping length limitation related to the inherent characteristics of conventional compressor technology.

[0006] Prior art refrigerant piping lengths were limited by the particular systems ability to maintain proper oil return, due to the necessary entrainment of lubricating oil present in conventional refrigerant lines to enable operation of conventional compressors.

[0007] The absolute maximum le...
