新型地铁空调系统变负荷运行的节能优化控制研究

Study of Energy Control Strategy for a Novel Subway Air Conditioning System under Various Load

今后的二三十年是我国城市地铁交通发展的高峰期,地铁车站通风空调系统是整个地铁工程的重要组成部分。本文以提高地铁环控系统节能整体方案,提出一种新型的冷媒直接蒸发空调系统,并在此基础上提出了空调系统变负荷时,基于系统最小能耗的节能控制方法。结果表明,基于最小系统能耗的节能控制方法可以大大提高空调系统在部分负荷时的能效比,减小系统能耗。

The urban rail transit system will be fast developed in decades in our country. The subway environmental control system plays an important role in the subway engineering. A novel coolant-direct-evaporation air conditioning system is presented to save land resource and money. The article presents an enhancement on energy-saving of metro coop-control system. The energy control strategy based on minimum energy consumption for various load of the system is researched. The result shows that the energy control strategy based on minimum energy consumption improves the energy efficiency ratio and reduce the system power consumption greatly in part load.
