Abstract
A refrigerant system having tandem compressors includes at least two compressors of different types. By utilizing the two distinct compressor types, a greater difference in the provided capacity of the two compressors can be achieved at part-load conditions, as well as a particular compressor type can be engaged at specific environmental conditions to provide the most efficient operation of the refrigerant system.
Claims22
A refrigerant system comprising:
- a tandem compressor unit including at least two compressors receiving refrigerant from the refrigerant system, compressing the refrigerant and delivering the refrigerant into the refrigerant system;
- a heat rejection heat exchanger positioned downstream of said tandem compressor unit, an expansion device positioned downstream of said heat rejection heat exchanger, and an evaporator positioned downstream of said expansion device, refrigerant passing from said tandem compressor unit to said heat rejection heat exchanger, through said expansion device to said evaporator, and back to said tandem compressor unit;
- and
- said at least two compressors of said tandem compressor unit being of distinct types.
