Design of Air-Conditioning System and Ventilation System in Web Press Workshop of One Printing Plant

Abstract

Air-conditioning and ventilation system which control temperature and humidity was designed in this paper. Its aim was to ensure the production process and meet the comfort requirements of workers. Considering that web press equipment load account for large proportion of the total load, we separated out the area of web press and the waste heat was discharged by ventilation system. We adopted Stratified air conditioning on the remaining area because the whole workshop is large space. By means of calculation, energy saving rate of stratified air conditioning system is 25.6% and the refrigerating capacity is reduced by this way of design. Energy-saving effect is remarkable. So it’s a good method to energy conservation.
