PROBLEM TO BE SOLVED: To eliminate brazing work in a completed product assembling process in an engine drive type heat pump. SOLUTION: The engine drive type heat pump 1 is provided with an equipment chamber 5 in which an engine 22 and refrigerant equipment such as compressors 20a, 20b are arranged; a heat exchange chamber 4 in which an outdoor heat exchanger 25 and an outdoor fan 26 are arranged; and a vertical partition wall 6 for partitioning a space between the lower equipment chamber 5 and the upper heat exchange chamber 4. A set of the refrigerant equipment including a four way valve 24 and a receiver 31 arranged in the equipment chamber 5 are in advance formed as one refrigerant equipment unit 50 before the completed product assembling process, and outdoor heat exchanger gas piping 45 for a gas refrigerant connection port of the outdoor heat exchanger 25 and the four way valve 24 and outdoor heat exchanger liquid piping 46 for a liquid refrigerant connection port of the outdoor heat exchanger 25 and the receiver 31 are interconnected by flanges in the vicinity of the vertical partition wall 6.
