of the complexity of the SENS cycle‚ another cycle was proposed by Maclaine-cross [7]‚ known as REVERS cycle. Only difference between SENS and REVERS cycle is‚ the later one uses single heat exchanger and exhaust air is used for desiccant wheel regeneration. Meckler [8] introduced desiccant air conditioning with two stage dehumidification. It is illustrated in Fig-5. Ambient air is used as supply air‚ which is dehumidified twice with intermediate cooling by return air. Return air is used for desiccant
