Abstract

World are faced with energy shortage. So the last issue of world is saving the energy. Also, there are efforts to reduce energy in the air conditioning. Through the improvement of industrial and quality of life, air conditioning had been applied many area not only residential and office but also industrial field such as chemical process, semiconductor process which need to control temperature and humidity precisely. The solar liquid desiccant air conditioning system can be alternative solution to control air condition and to save energy electrical energy consumption. This study focuses on to control the electrical heater in solar desiccant air conditioning system when regeneration is lower than dehumidifying to make balance dehumidifying with regeneration. This study suggests heater’s on/off control algorithm which use lagrange extrapolation. The algorithm is predicting time when dehumidification reach at set point. If there is lack regeneration to reach to goal same time, electrical heater will be turn on to increase regeneration and make balance amount of moisture it evaporated to air in regeneration process with absorbed to desiccant in dehumidification process. Through the experiment in this thesis, it proves its feasibility. Also this control algorithm is useful information to design the optimization of regeneration control in solar hybrid air conditioning system.
