Abstract (en)
[origin: EP3617602A1] A refrigerant detection device that can be used in common in device models having different structures, and an indoor unit of an air-conditioning apparatus that uses the refrigerant detection device. The refrigerant detection device and the indoor unit of the air-conditioning apparatus include a refrigerant-detection air passage having both ends connected to a main air passage extending from a suction port of the indoor unit of the air-conditioning apparatus to an air outlet of the indoor unit, and a refrigerant detection sensor that detects refrigerant in the refrigerant-detection air passage.
