PROBLEM TO BE SOLVED: To reduce piping work and reduce on-site construction, to improve workability and shorten a construction period, to reduce execution costs, and to decrease outbreak of water leakage when mounting a display of temperature and pressure to an air conditioner. SOLUTION: The temperature sensor not in direct contact with inner fluid is installed to the outside of a cold water pipe and a hot water pipe. A pressure sensor in direct contact with the inner fluid is installed at the inside of the cold water pipe and hot water pipe. A temperature sensor and a pressure sensor are connected to an operation part for calculating temperature and pressure by electrical wiring. A panel for display is installed on the outer surface of the air conditioner. Temperature and pressure values that are detected by connecting the panel for display with the operation part by electric wiring are displayed. COPYRIGHT: (C)2004,JPO
