【 摘 要 】

Described are designs, principle of operation and calculation technique for contact-type water-cooled air humidifiers in air conditioning systems. Presented is a range of rotor-type and film-type contact apparatuses working in adiabatic air humidification conditions. The said equipment has been devised as a result of experimental investigation in the University and is characterized with reduced specific consumption of materials, power and cost. Positive results are achieved by increasing the time of working media contact in the process of heat-mass trans fer and increase in heat-mass transfer area. A procedure has been devised to calculate the heat-mass transfer area, based on application of humid air I-d-diagram and number of transfer units which is determined by graphic integration method.
