Title:
FREEZER REFRIGERATOR
Document Type and Number:
Japanese Patent JP2014156965
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a freezer refrigerator capable of securing cooling performance even when heat insulation performance of a vacuum heat insulation material is deteriorated, without causing damage of the vacuum heat insulation material and increase of a manufacturing cost.SOLUTION: A freezer refrigerator includes: a main body 101 having a storage chamber formed in an inner part; a vacuum heat insulation material 13 arranged within a heat insulation wall of the main body 101; a compressor 25 which constitutes a part of a refrigeration cycle and has variable rotation speed; and a control device 12 which controls the compressor 25. Therein, the control device 12 sets an upper limit value of the rotation speed of the compressor 25 as a first speed during a period TL after activating a power source to the freezer refrigerator and, after the period TL elapses, the upper limit value of the rotation speed of the compressor 25 is raised to a second speed larger than the first speed.
