基于PMV指标的列车空调节能研究

目前列车空调基本上是定风量运行的，由于列车空调负荷随时间和地点变化，定风量空调系统无法达到令人满意的热舒适性，而且浪费能源。本文通过分析PMV方程的特点，提出以PMV指标作为控制变量的变风量空调系统应用于列车空调，分析该空调系统的控制原理；通过实例计算分析，验证列车使用变风量空调系统的可行性，得到变风量空调系统的节能潜力。

Research on energy-saving of train air-conditioning based on PMV index

Constant volume air-conditioning system is widely used in the train now and the air-conditioning load of the train varies with the temperature out of the train as well as man＇s metabolism. As a result, the thermal comfort of the carriage is very bad and a lot of energy is wasted. Applies variable air volume air-conditioning system based on PMV control to carriage, and studies the method of variable air volume air-conditioning system design. Analyzes the energy consumption of the train variable air volume air-conditioning system based on PMV control by one example.
