Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/025301
Kind Code:
In conventional refrigerator-freezers, as a means for heating the inside of the freezer such as a vegetable compartment, a heater is installed on the side wall, floor and the like in the compartment, or a condenstation attachment preventing pipe or the like on the high pressure side of the refrigerant circuit is disposed in the compartment. The present invention addresses the problem of the need of electric power for the heater, the inability of the high pressure-side pipe to provide heating when the compressor is stopped, and an increase in electric power consumption when the means for heating the inside of the freezer is utilized, and provides a refrigerator-freezer which is capable of heating the inside of a compartment without requiring power to be supplied to a heater, the compressor and the like, and thereby decreasing electric power consumption.
