家庭空调地暖舒适节能控制技术仿真研究

Simulation research on comfort and energy saving control for residential air conditioning and radiant system

辐射供暖系统连续运行具有较好的舒适性,但能耗较高,如何保证舒适性同时降低运行能耗成为一个重要课题。通过搭建家庭空调辐射系统仿真平台,研究了不同的运行控制策略的舒适性和能耗表现,发现了一些规律。首先搭建了模块化系统仿真平台,并基于实验进行了标定和验证。再基于系统仿真平台研究和对比了不同的控制策略的舒适性和能耗特性。在间歇运行条件下,空调地暖双开策略可以确保较好的节能量而不降低人在家时的舒适性,相比于传统定水温控制策略典型日节能量达35%。随着间歇时间越长,空调地暖双开策略节能越明显,但节能率可能受开启机组时的室外工况影响。此研究结果可以用于指导家庭空调地暖系统的控制设计和优化。

The radiant heating system brings excellent thermal comfort but consumes much energy.How to ensure comfort while reducing the operating energy consumption has become an important issue.By building a simulation platform for home air conditioning radiation system,studies the comfort and energy consumption performance of different operation control strategies,and finds some rules.Firstly,a modular system simulation platform was built,and calibration and verification were carried out based on experiments.Based on the system simulation platform,the comfort and energy consumption characteristics of different control strategies were studied.Under intermittent operating conditions,the air conditioning and radiant floor double-on strategy can ensure better energy saving without reducing thermal comfort when people are at home,compared with the traditional constant water temperature control strategy.The typical daily energy saving is up to 35%.The longer the interval,the higher energy saving is observed.The energy saving rate may be affected by the outdoor working conditions when the unit is turned on.The results can be used to guide the control design and optimization of home air conditioning floor heating systems.
