Control System Design for Solar Energy with LHTS to Fresh Air Conditioning

With the help of LHTS (Latent Heat Thermal Storage) tank to primary Air Conditioning, a fresh air system of solar energy storage with LHTS is presented. In this paper, heat transfer characteristics of the system and Energy-saving optimizing design method for the compounded system were firstly studied. Then the structure of hardware and software were designed for, and the field and remote monitoring control, basing on CAN bus with the help of ICAN Module and TCP/IP technology, were finally realized. It is proved that there are the following advantages for the control system: easy system operating, convenient monitoring interface for users, flexible network structure based on iCAN protocol, high reliability, convenient to test and develop, and affluent in PC driver supporting which escapes away from the instability and discontinuity of individual solar energy air conditioning system.
