Abstract
Leakage of a heating medium from a condenser or an evaporator can be quickly detected by a simple structure. A refrigeration apparatusaccording to the present invention is formed by connecting a compressor, a condenser, an expansion valveand an evaporatorby a pipesuch that a heating medium circulates therethrough in this order. The refrigeration apparatusfurther includes a pressure detection unitthat detects a pressure of the heating medium flowing through the pipe, and a control unitthat determines that leakage of the heating medium from the condenseror the evaporatorhas occurred, when a pressure detected by the pressure detection unitbecomes not more than a predetermined value.
