Abstract
A refrigerant system includes two compressors that are independently activated to meet a variable cooling demand of a comfort zone or a process. For high cooling demands, both compressors are operated. However, for lower cooling demands, one compressor is de-activated, while the other continues running. To help prevent refrigerant from condensing in the vicinity of the relatively cool inactive compressor, heat from the discharge line of the running compressor heats the suction or discharge line of the inactive compressor. To transfer heat from one line to the other, the two lines are simply held against each other in a parallel, side-by-side relationship.
