PROBLEM TO BE SOLVED: To provide a cooling method with injected liquid, which solves the problem that since a material used in a rotor, a coat and the like is not unlimitedly resistant to a high temperature, a temperature in the compressed-air outlet of a compression element part needs to be prevented from excessively rising.SOLUTION: A cooling method of a liquid type injection compressor element part, in which liquid is injected from an injection valve 13 to the compression chamber of a compressor element part 2, includes a step of controlling an amount of liquid injected to the compression chamber of the compressor element part 2 according to a specific control parameter, regardless of other adjustable devices. |
