Bypass air conditioning systems are divided into three types; an outdoor air bypass, a mixed air bypass and a return air bypass system. What makes the return air by pass system more effective is that it directs all of moist outdoor air through the cooling coil. The bypass air conditioning system can maintain indoor R.H (Relative Humidity) less than a conventional CAV (Constant Air Volume) air conditioning system by adjusting face and bypass dampers at part load. When a design sensible load (the ratio of sensible load to total sensible load) is 70 percent (at this time, RSHF (Room Sensible Heat Factor) . 0.7), indoor R.H was maintained 59 percent by the return air bypass system, but 65 percent by the conventional CAV air conditioning system (valve control system). The bypass air conditioning system can also improve IAQ (Indoor Air Quality) in many buildings where the number of air change is high.

The humidity control is conducted not only for industrial applications but also for domestic ones. High humidity is a factor causing discomfort, thus the importance of using a LiCl(Lithium Chloride) solution has been recognized in recent years in connection with the high quality of goods to be manufactured. as well as cleanliness in a special environment against air pollution and environmental protection. This paper will examine the solar energy regenerator as a part of an open cycle solar energy absorption system for dehumidifying and drying purposes using LiCl solution. An outdoor experiment was done to find out how much could be regenerated in summer. It was found that regeneration rate was about 10kg/day at best in August, and about 5kg/day in September.
