PROBLEM TO BE SOLVED: To reduce the number of parts constituting a fuel suction system, miniaturize an outdoor machine unit and reduce manufacturing cost by combining and integrally constituting at least two of a suction box, a muffler and an air cleaner which constitute the fuel suction system. SOLUTION: In an outdoor machine unit provided with an outdoor heat exchanger, a compressor feeding gas coolant to the outdoor heat exchanger or an indoor heat exchanger, a gas engine driving the compressor, an exhaust gas heat exchanger collecting heat of exhaust gas exhausted from the gas engine in cooling water of the gas engine and utilizing heat for heating coolant, a suction box 73 suppressing generation of suction sound, a muffler 74 silencing generated sound and an air cleaner 75 removing dust contained in sucked air, these suction box 73, muffler 74 and air cleaner 75 are combined and are integrally constituted. |
