Abstract:
1. A refrigerant system comprising: a tandem compressor bank including a plurality of compressors receiving refrigerant from a suction manifold, compressing the refrigerant and delivering the refrigerant into a discharge manifold; a condenser positioned downstream of said compressor bank, an expansion device positioned downstream of said condenser, and an evaporator positioned downstream of said expansion device, refrigerant passing from said compressor bank to said condenser, through said expansion device to said evaporator, and back to said suction manifold; and at least one sensor for sensing a refrigerant system operating condition, and a control for being operable to monitor said operating condition as each of said tandem compressors is brought online, and identify a refrigerant system fault based upon expected changes in said operating condition as each of said tandem compressors is brought online.
