Abstract: Dehumidification and cooling performance are two most important features of a direct expansion (DX) cooling coil, which works as an evaporator for a DX air-conditioning system. The condensing rate and the sensible heat transfer resistance of a DX cooling coil represent its capacity for dehumidification and is an important characteristic of the cooling process. An experimental investigation on the effects of the indoor environment, that is, indoor air temperature and relative humidity (RH), on the condensing rate and the air-side sensible heat transfer resistance of a DX cooling coil has been conducted and is reported in this paper. It was found that both the condensing rate and the air-side sensible heat transfer resistance increased with increase of indoor air RH and decreased with an increase of indoor air temperature. Correlation of the experimental results of the condensing rate and the air-side sensible heat transfer resistance under different indoor air temperatures and RH were studied.
