An Assessment of Energy Consumption in Steam-Humidification- and Water-Spray-Humidification-Type Outdoor Air Conditioning Systems for Semiconductor Manufacturing Clean Rooms

Experimental study for hybrid humidification–dehumidification water desalination and air conditioning system

• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...

Adding amines to steam for humidification

Humidification of the air passages.

The reasons for moistening of the mucous membranes are several. Ciliary action is dependent on a supply ofmucus, of the right viscosity and in correct amount; in this blanket of mucus are carried lysozymes, described by Fleming (1928), of considerable bacteriostatic and bactericidal importance. The alveoli of the lung must be kept moist, for otherwise respiratory exchanges cannot be carried on;...

Air-Heating Solar Collectors for Humidification-Dehumidification Desalination Systems

Relative to solar water heaters, solar air heaters have received relatively little investigation and have resulted in few commercial products. However, in the context of a humidification-dehumidification (HDH) desalination cycle, air heating accounts for advantages in cycle performance. Solar collectors can be over 40% of an air-heated HDH system’s cost; thus, design optimization is crucial. Be...

Energy Saving System for Air Conditioning of Clean Room for Semiconductor Factory (Estimation of FMU System)

The total power consumption of all semiconductor plants exceeds 100 million kWh per year, with about 43% of this consumption to operate air conditioning facilities. This high power consumption is due to the requirement of the cleanliness kept for clean rooms, with extremely high power consumed to the air transferring power. Oki developed the fan module unit (FMU) type air conditioning system to...
