    • PROBLEM TO BE SOLVED: To provide a heat transfer medium for solving a problem of CO 2 having excellent characteristics as a heat transfer medium, and to provide a heat transfer device which uses the heat transfer medium which serves as a secondary heat transfer medium, or is used for a natural circulation type heat pump cycle which operates at a low pressure, exhibits a favorable coefficient of performance, and is convenient in use. SOLUTION: The heat transfer device uses the heat transfer medium c mainly containing CO 2 as the heat transfer medium for heat transfer equipment 1 for cooling or heating. The heat transfer medium c formed by adding dimethyl ether in a molar ratio of 1-50% to CO 2 is used as the secondary heat transfer medium r 2 interposed between a heat exchanger of a primary heat pump cycle and a heat load, for transferring heat between the primary heat pump cycle and a heat load.

    • PROBLEM TO BE SOLVED: To provide a cooling device and a cooling method of a workpiece capable of preventing temperature rise of a main line (cold air supply line), when a cold air is not supplied to the workpiece. SOLUTION: This cooling device is equipped with a workpiece holding container 3 for storing the workpiece 2 to be cooled, a cold air generation device 4 for generating the cold air, the main line 5 for supplying the cold air generated from the cold air generation device 4 to the workpiece holding container 3, and a sub-line 6 for circulating the cold air generated from the cold air generation device 4. The main line 5 and the sub-line 6 have a main line heat exchanging part 5a and a sub-line heat exchanging part 6a to be in contact mutually heat-exchangeably, respectively, and when the cold air is not circulated in the main line heat exchanging part 5a, the cold air is circulated in the sub-line heat exchanging part 6a, and the main line heat exchanging part 5a is cooled.

    • PROBLEM TO BE SOLVED: To provide a cooling system cooling communication equipment while protecting the communication equipment from condensed dew drops. SOLUTION: A refrigerant amount supplied to an indoor heat exchanger 3 is controlled such that relative humidity on the surface of the indoor heat exchanger 3 becomes a prescribed value. Thereby, generation of the dew condensation water (condensed water) on the surface of the indoor heat exchanger 3 can be prevented before it happens. Accordingly, suppose that a worker brings water into a cellphone base station 1, dropping of the dew condensate onto the communication equipment 2 can be prevented before it happens, so that is is not necessary to take measures such as arrangement of a drain pan or the like receiving the dew condensate on the lower side of the indoor heat exchanger 3. As a result, because heat generated in the communication equipment 2 and air heated by the communication equipment 2 are not blocked, the heat generated in the communication equipment 2 can be efficiently recovered by the indoor heat exchanger 3 to cool the communication equipment 2 while protecting the communication equipment 2 from the condensed dew drops.
