摘要： An air conditioner selection system according to the present invention is capable of efficiently selecting an air conditioner that satisfies a safety standard requirement in a case where a refrigerant leaks. An air conditioner selection system (100) is a system for selecting an air conditioner (50) including an indoor unit (52). The air conditioner selection system (100) is provided with a floor area acquisition section (12a), an allowable refrigerant amount acquisition section (12b), and an air conditioner selection section (12c). The floor area acquisition section (12a) acquires a floor area of a room (3) where the indoor unit (52) is to be installed. The allowable refrigerant amount acquisition section (12b) acquires an allowable refrigerant amount of a refrigerant allowed to remain in the room (3) at least based on the floor area acquired by the floor area acquisition section (12a). The air conditioner selection section (12c) selects the air conditioner (50) including the indoor unit (52) installable in the room (3) at least based on the allowable refrigerant amount acquired by the allowable refrigerant amount acquisition section (12b).

摘要： An air-conditioning device includes: a suction air temperature sensor provided in an indoor unit; a wireless temperature sensor unit separate from the indoor unit; an abnormal condition determining section determining whether or not the wireless temperature sensor unit is in an abnormal condition; an index setting section setting a temperature index value; and a controller controlling operation of the air-conditioning device based on the set temperature index value. While the abnormal condition determining section determines that the wireless temperature sensor unit is in the abnormal condition, the index setting section determines a measurement value of the suction air temperature sensor to be the temperature index value.

摘要： An indoor unit, being configured to constitute a refrigeration apparatus including a refrigerant circuit, includes: a heat exchanger; and a plurality of refrigerant pipes. R32 refrigerant is enclosed in the refrigerant circuit. At least one of the plurality of refrigerant pipes that circulates the R32 refrigerant has an outer diameter of (Do-1)/8 inches while another of the plurality of refrigerant pipes that circulates R410A refrigerant has an outer diameter of Do/8.

摘要： A receiver unit includes: a receiving section receiving a signal of a measurement value (Tm2) transmitted from a wireless temperature sensor unit; an input connector connected to a sensor signal line, the sensor signal line being configured to transfer a signal of a measurement value (Tm1) of the suction air temperature sensor; a signal generator generating a signal serving as an index of indoor temperature, based on the measurement values (Tm1, Tm2) of the wireless temperature sensor unit and the suction air temperature sensor; and a signal output section outputting the signal generated by the signal generator to a controller of an air-conditioning device.
