Refrigeration facility

Abstract

A refrigeration facility such as a refrigeration container includes a refrigeration device cooling an interior of the refrigeration facility and including an evaporator allowing air inside the refrigeration facility to pass through. A condensate port serving as a corrosive gas detector is installed in a drain hose. The drain hose disposes condensate water from a drain pan, which collects condensate water generated by the evaporator. Detecting corrosive gas in the air inside the container by using a pH sensor to examine a pH value of condensate water in the drain port allows for reducing the risk of corrosion of components installed inside the container.
