Air conditioning system in data centers must cool year-round due to the large amount of heat emitted from the IT equipment. Therefore, it’s effective for air conditioning system to use low temperature outdoor air as direct/indirect air-side economizer. Air-side economizer can reduce energy consumption during cold season, but mechanical cooling such as refrigerant cycle must run during other season. Thus, we aim to develop high efficiency refrigerant cycle for saving energy consumption during hot season. So, we focus to the gas injection cycle. In this report, we verify to get guidelines for applying gas injection cycle to packaged air conditioner for data centers.
