PURPOSE: A gas engine driving type air conditioning apparatus is provided to reduce harmful vibration generated in a connecting pipe connecting compressors and a heat exchanger. CONSTITUTION: A gas engine is driven by combustion of fuel gas. Compressors(13,13B) are driven by the gas engine. A heat exchanger exchanges heat for air-conditioning a refrigerant compressed by the compressors. A container(80) is installed in a refrigerant pipe connecting the compressors with the heat exchanger, having a suction port(80m) sucking the refrigerant discharged from discharge ports(19) of the compressors, and a hollow chamber(80p) communicated with the suction port. When pipe length from the discharge ports of the compressors to the suction port of the container is represented by L, and the velocity of sound in the refrigerant is represented by C, and rotating frequency of the compressors for one second is represented by N, the L is smaller than C/(2*N).
