Multiple compressor heat pump or air conditioner

摘要: In a refrigeration system (10), multiple compressor for maintaining the heat output constant while outside ambient temperature continues to decrease. The present invention comprises primary (31) and at least one secondary (32). entire is sized operating in cooling mode. heating mode, operates by itself until (60) falls within particular range. Once this range met, (32) begins conjunction with such that mass flow of refrigerant through mode operation no greater than alone While decrease, additional compressors may be included maintain output. only single required operate system. Each alternate any other so lives are preserved.
