考虑舒适度的空调节能方法研究

Research on energy-saving method of air conditioning with consideration of comfort

研究空调的能耗与温度设置值的关系,将空调的能耗建立为与温度相关的函数模型;在Matlab中通过编程求出空调在不同设置温度下的室内热舒适温度指标(Predicted Mean Vote,PMV)随时间变化的情况;接着以空调能源消耗花费最少为优化目标,在满足人体舒适度的基础上对空调的设置温度进行约束;最后通过算例表明优化空调的设置温度可以降低一天的耗能费用。

The relationship between the energy consumption of air conditioning and the setting value of temperature is studied, and a model of the function of energy consumption of air conditioning is set up. Matlab is used to find out the change of predicted mean vote with time under different setting temperatures. On the basis of satisfying the comfort degree of the human body, the air conditioning temperature is constrained, and the minimum consumption of air-conditioning energy consumption is the optimization objective. Finally, an example shows that optimizing the setting temperature of air conditioning can reduce the energy consumption cost.
