PROBLEM TO BE SOLVED: To heat a compressor without using electricity and a boiler, thereby vaporizing a refrigerant condensed in a compressor, reliably performing lubrication in a bearing part, etc., and preventing liquid compression in the compressor.SOLUTION: In a vapor compression type heat pump 1, heat is pumped up from a heat source fluid in an evaporator 5, and a fluid to be heated is heated in a condenser 3. A compressor heating part 21 supplied with the heat source fluid to heat the inside of the compressor 2 is provided on the outside of a shell 9 of the compressor 2. In addition, an accumulator heating part 29 supplied with the heat source fluid to heat the inside of an accumulator 6 may be provided on the outside of the accumulator 6. |
