WIPO Patent Application WO/2021/215528

A1

The present disclosure relates to a ceiling-mounted air conditioning indoor unit (1) for a heat pump comprising a refrigerant circuit, the indoor unit comprising: a casing (2) comprising an air inlet (2a) and at least one air outlet (2b); a drain pan (3) in a bottom portion of the casing (2), the drain pan (3) having an first rim (3a) and an second rim (3b); a heat exchanger (4) being part of the refrigerant circuit and arranged above the drain pan (3) so that water dropping from the heat exchanger (3) accumulates in the drain pan (3); a fan (5) accommodated in the casing (2) to draw air in the air inlet (2a) through the heat exchanger (4) and out of the at least one air outlet (2b), a bell mouth (6) located at the air inlet (2a) for guiding drawn in air to the fan (5), a refrigerant leakage detection sensor (7) for detecting refrigerant leaking from the refrigerant circuit, wherein the refrigerant leakage detection sensor (7) is positioned between an outer surface (8) of the second rim (3b) of the drain pan (3) and an inner surface (9) of the bell mouth (6), wherein the outer surface (8) of the second rim (3b) of the drain pan (3) and the inner surface (9) of the bell mouth (6) face each other.
