PROBLEM TO BE SOLVED: To inject a liquid for refrigerant in a circulation channel easily and in a short time and also to enable injection of the liquid for refrigerant in a deaerated state by constructing a heat absorbing system unit by integrating a second circulating pump, a thermoelectric heat exchange block, a heat exchanger for cooling and a piping connecting these components. SOLUTION: An injection jig 98 is used for injection of a liquid for refrigerant and the injection is conducted by putting a pump body 91 in a non-driven state. The liquid for refrigerant is made to flow in the sequence of the pump main body 91→a discharge port 94→a thermoelectric heat exchange block→a heat exchanger for cooling→an inlet 93 by a force of pressure sending of a refrigerant supply pump 97 and returns to a chamber main body 92a. Then, the liquid for refrigerant overflows outside from a liquid overflow pipe 98c. By stopping the pressure sending of the refrigerant supply pump 97 at this time point, the liquid for refrigerant can be filled up in a second circulation system of a heat absorbing system unit. By disengaging the injection jig 98 from the chamber main body 92a and fitting it to a cap main body 92b thereafter, the operation of injection of the liquid for refrigerant is finished.
