PURPOSE: A power-saving air conditioning system using a gas engine heat pump is provided to execute cooling, heating, and humidification at low costs by using a gas engine driven by natural gas. CONSTITUTION: A power-saving air conditioning system is formed of an indoor unit(11) and outdoor units(31). The outdoor unit is formed of a freezing apparatus realizing a refrigerating cycle. A refrigerant compressor of the outdoor unit is driven by a gas engine. Heat exchangers installed in the outdoor unit are used for both condenser and evaporator. A four-way valve is installed at the refrigerating cycle for converting the refrigerating cycle into a heating cycle. A vaporizing humidifier(19) is installed in the indoor unit. Plural heat exchangers(13A,13B,13C) are installed in the indoor unit.
