In a refrigeration facility, such as a refrigeration container, comprising a refrigeration device (10) that cools inside a compartment and has an evaporator (24) through which compartment air passes, corrosion of members provided in the compartment is suppressed as a result of: providing a drain water port (43) as a corrosive gas detection unit (50), in a drain hose (42) that discharges drain water from a drain pan (41) that receives the drain water generated by the evaporator (24); and investigating the drain water pH at the drain water port (43), by using a hydrogen ion index sensor (45), and detecting corrosive gas in the compartment air. |
