The first case was using a chiller in air handling unit, and a solution dehumidification system was installed in front of the system to carry out analysis of energy-saving efficiency, the second one is that the systems with direct expansion air-conditioning system and it has been installed with a total heat exchanger, and compared with the direct expansion air-conditioning which has been installed with a solution dehumidification system. The make-up air unit (MAU) first uses the solution dehumidification system for treatment before introducing the outside air into the MAU, and analyzes the energy efficiency before and after the installation of the comparison period. The above-mentioned solution dehumidification system is used as the outside air before the first step. Through the above three cases of situational assumptions, energy conservation benefits were analyzed separately, and the reasons for achieving energy savings were explored. Solution dehumidification can be preceded by effective outside air pretreatment. The treated outside air is already quite stable, regardless of the back end. The chiller unit, the direct expansion air conditioner, or the make-up air unit all reduce a considerable amount of heat load, resulting in a significant decrease in the load on the chilled water side so that the energy saving can be effectively performed after the dehumidification system who has been installed.
