生活空间环境控制系统的能效提升与节能技术应用分析

Analysis of Energy Efficiency Improvement and Energy-saving Technology Application of Living Space Environment Control System

摘要:

为响应"双碳"与乡村振兴战略融合要求,解决北方寒冷地区农宅厨卫通暖能耗高、舒适度差的问题,文章以铜川市农宅为研究对象,采用DeST能耗模拟、正交试验与工程实证相结合的方法,围绕围护结构保温优化、可再生能源耦合及智能调控三大核心技术路径开展研究。结果表明,50 mm厚的EPS外墙保温、50 mm厚的XPS屋面保温与塑钢中空玻璃窗的组合方案,可使厨卫通暖能效提升率达40%以上;叠加太阳能阳光间技术后,能效提升率最高可达59%,且冬季采暖费用可降低约30%。

Abstract:

In response to the integration requirements of the "dual carbon" and rural revitalization strategies, and to solve the problems of high energy consumption and poor comfort in the kitchen and bathroom of rural houses in cold northern regions, this article takes rural houses in Tongchuan City as the research object, and adopts a combination of DeST energy consumption simulation, orthogonal experiment, and engineering empirical method to conduct research around three core technology paths: insulation optimization of enclosure structure, coupling of renewable energy, and intelligent regulation. The results show that the combination of 50 mm thick EPS exterior wall insulation, 50 mm thick XPS roof insulation, and plastic steel insulated glass windows can improve the energy efficiency of kitchen and bathroom heating by more than 40%. After combining solar photovoltaic technology, the energy efficiency improvement rate can reach up to 59%, and the winter heating cost can be reduced by about 30%.
