Document Type and Number:

WIPO Patent Application WO/2007/119414

Kind Code:

A1

Abstract:

A cooling medium heating apparatus which has improved controllability and reduced power consumption, and a method for controlling heating of such cooling medium heating apparatus are provided. The cooling medium heating apparatus (4) is provided with a heater (12) and a control section (17). The heater (12) heats a cooling medium. The cooling medium flows inside a cooling medium circuit (10) including a compressor (22). The control section (17) controls operation of the heater (12).
