| Abstract: | In this paper, an automatic measure and control system is developed which is used for handling a large number of data and achieving automatic control to the liquid desiccant air-conditioning system. The hardware part of the measure and control system consists of data collection unit and test instrument, while the measure and control software is programmed with Visual Basic 6.0, accompanied with the Microsoft Access database. The PLC unit and the touch screen are employed for local control of the system to achieve precise adjustment to the temperature of heat source, the speed and flow of air. Experiments prove that the measure and control system has a favorable performance and can meet the requirement of the measure and control to the liquid desiccant air-conditioning system. |
