Container refrigeration device
First Claim
1. A container refrigeration device with a refrigerant circuit including a compressor, a condenser, an expansion mechanism, and an evaporator which are sequentially connected together, and with an inside fan configured to blow inner air having exchanged heat in the evaporator of the refrigerant circuit to an inside of a container, a rotation speed of the inside fan being variable, the container refrigeration device comprising:
- a fan controller which reduces the rotation speed of the inside fan when a temperature inside the container has continuously remained within a predetermined temperature range set relative to a target temperature; and
a rotation speed controller which, in response to the reduction of the rotation speed of the inside fan by the fan controller, reduces an operational rotation speed N of the compressor such that the temperature inside the container becomes equal to the target temperature.

Abstract
A container refrigeration device includes: a fan controller which reduces a rotation speed of an inside fan when a temperature inside a container is stabilized; and a rotation speed controller which reduces an operational rotation speed N of a compressor such that the temperature inside the container becomes equal to a target temperature as the fan controller reduces the rotation speed of the inside fan.
