The object of this invention is to provide an air conditioning system with low compression load. This air conditioning system consists of an expansion unit for adiabatically expanding refrigerant, an indoor unit having a heat exchanger, a compressor for adiabatically compressing the refrigerant, and an outdoor unit having a heat exchanger, and circulates refrigerant through the compressor, outdoor unit, expansion unit, and indoor unit to heat or cool a target area using the phase change of the refrigerant. In an embodiment, the air conditioning system (100) is designed such that condensed refrigerant from the indoor unit (120) or the outdoor unit (140) passes through a sub-evaporating unit (150) prior to flowing into the expansion unit (110), with the refrigerant from the sub-evaporating unit (150) partially flowing into a sub-expansion unit (171) to be adiabatically expanded to become low temperature, low pressure bypassed refrigerant prior to flowing into the compressor (130) through the sub-evaporating unit (150). |
