摘要： PURPOSE: To improve a refrigerant heater which feeds a refrigerant being heated by heat-exchanging with a combustion gas being burnt by a gas burner, etc., to a compressor to perform a heating operation so that the refrigerant heater can be easily built up by the simplification of constituent parts, and the cost may be reduced, and a high combustion efficiency may be obtained, and the refrigerant heater may become light-weight, etc. CONSTITUTION: A refrigerant heater 10 consists of a combustion device being equipped on the bottom, such as a gas burner 7, and a heat-exchanger which is connected to the top of the combustion device, and wherein a refrigerant returning to a compressor in a refrigerant tube 3 being provided under a zig-zag state on the external surface is heated by a combustion gas stream passing through an internal passage. For such a refrigerant heater 10, the main body case part 40 is constituted by integrally forming an apparatus case 9 which is the external surface member of the heat-exchanger and a box body 6 of the combustion device in which the gas burner 7 is housed. By doing so, labor to build up and combine a heat-exchanger and a combustion device which are conventionally separate parts, can be eliminated, and the insertion of a packing becomes unnecessary, and the efficiency of the production can be improved, and the cost can be reduced. At the same time, the heat-exchanging performance of the refrigerant heater 10 can be made favorable.
