Abstract: An sure, an inspection system and an inspection method that reduce the time required to inspect environmental microorganisms, are provided. The inspection system inspection system is for inspecting a microorganism or mold that is generated in an indoor environment or a device, and the inspection system includes an imaging unit configured to directly capture a sample collected from the indoor environment or the device; and an output unit configured to inspect the microorganism or the mold in image data captured by the imaging unit, and output an inspection result.

Abstract: A copper-containing refrigerant pipe having an anticorrosive film, a heat exchanger, and a method for producing the refrigerant pipe are disclosed. The refrigerant pipe includes a pipe body including copper or a copper alloy and an anticorrosive film formed on the outer surface of the pipe body. The anticorrosive film is obtained by applying a coating agent to the outer surface of the pipe body. The coating agent contains one or more anticorrosive agents selected from the group consisting of (A) an organic sulfonate compound, (B) a polyhydric alcohol-organic acid ester compound, and (C) an aliphatic amine compound having 8 to 24 carbon atoms. When the coating agent includes an anticorrosive agent of (C) the aliphatic amine compound having 8 to 24 carbon atoms, (C) the aliphatic amine compound having 8 to 24 carbon atoms is included in an amount of 2.0 wt % or more and 10.0 wt % or less in the coating agent.
