摘要： Provided is a method for monitoring an air-conditioner having a semi-conductor gas sensor, comprising: determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a first threshold when the fan is in operation (S1200, S1300, S2400); starting operation of the fan as a provisional operation if the detection value is equal to or greater than a second threshold when the fan is not in operation (S1200, S1400, S1800); stopping the provisional operation of the fan (S1800); determining that a refrigerant leakage has occurred on condition that the detection value is equal to or greater than a third threshold after stopping the provisional operation of the fan (S2100, S2400); and taking a predetermined action for outputting alarm information and/or limiting supply of refrigerant to the heat exchanger when a refrigerant leakage is determined to have occurred (S2400).

摘要： A remote control (30) which is installed on a sidewall (SW) and carries out wired communication with an indoor unit (20) has a touch panel (70) including an electrode unit (71), a liquid crystal display (60) disposed so as to overlap the touch panel (70) as seen from a front surface part (32) side, and a casing (31). The casing (31) has a back surface part (33) that faces the sidewall (SW) in an installed state and the front surface part (32) that faces the indoor space (SI) in the installed state. The electrode unit (71) has a touch electrode section (72) that functions as an electrode for detecting a touched position, and an antenna electrode section (73) that functions as an antenna for performing wireless communication with an external communication device (110). The touch electrode section (72) and the antenna electrode section (73) are nearer to the front surface part (32) than to the back surface part (33) inside the casing (31) and are disposed so as not to overlap with each other as seen from the front surface part (32) side.
