Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a refrigerant heating device capable of reducing system costs even when a plurality of object portions are heated. SOLUTION: A power unit 60 as a refrigerant heating device for heating a refrigerant circulating in refrigerant piping 20, comprises a first coil 62b, a second coil 62c, an electric power output portion 66, an acquiring portion 64, and an output control portion 65. The first coil 62b heats the refrigerant circulating in the first refrigerant piping 20b. The second coil 62c heats the refrigerant circulating the second refrigerant piping 20c. The electric power output portion 66 heats both of the first coil 62b and the second coil 62c by changing output power. The acquiring portion 64 acquires information relating to heating degrees requested in the first coil 62b and the second coil 62c. The output control portion 65 controls output electric power of the electric power output portion 66 to the first coil 62b and the second coil 62c on the basis of a result of acquisition by the acquiring portion 64.
