数字化热湿环境监测在医院中央空调节能中的应用

Application of Digital Thermal Moisture Monitoring in Hospital Central Air Conditioning

建立了基于局域网和数字化传感器的空调用户热湿状态监测硬件和软件系统,实现了对空调环境的热湿状态的实时监测。针对风机盘管加新风空调系统,提出用实时曲线和空调环境热舒适度图指导节能的措施,用室内外温度相关性系数作为空调系统和建筑围护结构隔热性能的评价指标。实际应用表明,空调环境热湿状态监测系统能有效地指导空调系统的节能运行。

A temperature and humidity supervising system, including hardware and software system, was built based on local area nerwork（LAN） with g digitalized sensors to acquisit the realtime temperature and humidity data from air- conditioned spaces. A realtime temperature curve chart and a thermal comfort chart was adopted to operating strategy for energy-saving of fan-coil type central air-conditioning systems. The correlation coefficient of the inner and outer temperature histories was used to evaluate the operating performance of air-conditoning systems and the thermal insulation of building enclosures. It is shown in practical operation that the supervising system is helpful for efficiently operating air-conditioning systems.
