Document Type and Number:
WIPO Patent Application WO/2021/010296
Kind Code:
A1
Abstract:
In adopting a flammable refrigerant, it is necessary to install a gas sensor that detects the refrigerant in case of a refrigerant leak, and the present disclosure addresses the problem of selecting the installation location of the gas sensor. A gas sensor (55) is installed above a drain pan (36) in a side view, and the height H from the upper end of the drain pan (36) to the gas sensor (55) is set so as to satisfy the relational expression of L∙W{C1∙H1/Q+C2∙H/(Q-C3∙L∙H^(3/2))} ≤ 90, where the constant C1: 0.0067, the constant C2: 0.01172, the constant C3: 0.000153, L [m]: length of the first wall surface of the drain pan (36), W [m]: length of the wall surface of the drain pan (36) that intersects the first wall surface, H1 [m]: depth of the drain pan (36), and Q [m^3/s]: refrigerant leakage rate.
