<p>A conductive fluid detector (10) for detecting water content mixed in refrigerant (30), comprising a tubular member (211) permitting the flow of refrigerant (30), mesh members (122, 124) consisting of stainless steel or the like, and filter paper (123) being permeable to refrigerant (30) but capable of retaining water content, wherein the mesh members (122, 124) and the filter paper (123) are provided in layers in the tubular member (121), and the filter paper (123) is provided with a filter unit (12) interposed between the mesh members (122, 124), a resistance measuring circuit (16) for measuring a resistance between the mesh members (122, 124), and a relay (17) for stopping power supply to a pump (14) when a resistance between the mesh members (122, 124) lowers.</p> |
