Abstract

Disclosed herein is a refrigerator for a refrigerating vehicle using an ejector and a method for controlling the same. According to the present invention, a refrigerator for a refrigerator vehicle comprises a vapor compressor system where a compressor, a condenser, a refrigerant tank, an expansion valve, and an evaporator are connected through a flowing line, an ejector refrigerant system whose one end connected to an outlet of the refrigerant tank and whose other end connected to an inlet of the compressor, a flow control valve for distributing a refrigerant flowing between the ejector refrigerant system and the outlet, and a controller connected to an engine of a refrigerating vehicle connected to control the flow control valve if an RPM of the engine exceeds a setting value.
