ABSTRACT:
This invention presents an air condition utility system for providing air condition to sets of buildings, with each building having a number of amended air conditioning systems, by repeatedly circulating a refrigerant in a closed loop. Each station is connected to an assigned set of buildings of a district by high-pressure lines and low-pressure lines. High-pressure lines are used to transfer the refrigerant, in a liquid stage, from a station to each building that is served by the station. Upon providing air condition to a building, the refrigerant loses pressure and returns in a partial-gas partial-liquid stage through downwardly-sloped low-pressure lines from the building to the station. In the station, the refrigerant is pressurized by passing through a number of compressor units and again leaves the station in a liquid form through the high-pressure lines.
