Title:
REFRIGERANT HEATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2007/063916
Kind Code:
A1
Abstract:
A refrigerant heating apparatus is provided to reduce system cost even in the case
that a plurality of subject portions are heated. A power unit (60) as a refrigerant heating
apparatus to heat a refrigerant flowing through a refrigerant pipe (20) includes
a first coil (62b), a second coil (62c), a power output unit (66), an acquisition unit
(64) and an output control unit (65). The first coil (62b) heats the refrigerant flowing
through the first refrigerant pipe (20b). The second coil (62c) heats the refrigerant
flowing through the second refrigerant pipe (20c). The power output unit (66)
heats both first and second coils (62b) and (62c) by changing an output power.
The acquisition unit (64) acquires information of heating levels required in
the first and second coils (62b) and (62c). The output control unit (65) controls
the output power of the power output unit (66) supplied to the first and second
coils (62b) and (62c) in accordance with a result acquired by the acquisition unit
(64).
