地板辐射与新风耦合制冷系统的热舒适度分析

Study on the Control Strategy of PMV for Floor Radiation Coupled with Fresh Air Refrigeration System

目前,地板辐射供冷与新风耦合制冷系统发展迅速。利用Trnsys软件进行仿真模拟,研究了不同地板温度与室内空气温度组合对室内热舒适性的影响。进而,我们得到了该系统的PMV计算模型。这一理论模型对于地板辐射供冷与新风耦合制冷系统的控制策略具有很强的指导意义。人们可以根据想实现的PMV值来调节室内空气温度和地板表面温度。

At present,radiant floor and fresh air coupled cooling systems are developing rapidly.This paper uses Trnsys software to simulate and study the effect of different floor surface temperature and indoor air temperature combinations on PMV.Then,we get the PMV theoretical model of this system.This theory has a strong guiding significance for the control strategy of the radiant floor and fresh air coupled cooling systems.People can regulate and control the indoor air temperature and floor surface temperature according to the desired PMV value.
