介绍变新风温湿度独立控制空调系统的原理及构成,该空调系统利用房间湿度控制新风量,利用干式风机盘管机组的三速风机及水阀控制室内温度,利用新风阀控制室内湿度。对采用高温冷源的空调系统末端和热泵全热回收新风机组的控制及运行环境进行分析。
This paper introduces the principle and composition of air temperature and humidity independent control air conditioning system. The air conditioning system uses room air humidity to control the fresh air volume. It uses the third speed fan and water valve of dry fan coil unit to control the indoor temperature. The control and operating environment of the air-conditioning system with high-temperature cooling source and the heat recovery heat pump unit are analyzed.
