Study on a two-evaporator system for humidity control.

A feasibility study was performed on a two-evaporator system for humidity control. The two-evaporator system considered requires the addition of a reheat coil to the conventional unit. The reheat coil serves to reheat the cooled air leaving the cooling coils, thereby controlling the relative humidity. An experimental study was performing using a modified commercial ceiling concealed air conditioning unit. Results from the experiments show that the dehumidification capability is improved by 11%. However, the cooling performance was reduced by 13%. It is possible to control the relative humidity of the leaving air by adjusting the refrigerant temperature at the inlet of the reheat coil but at the cost of cooling performance.
