摘要
搭建了空气源热泵直接地板辐射采暖的实验平台,对其采暖效果、运行能效以及蓄热效果进行实验研究。结果表明,新型系统供暖效果良好,-10℃以上环境温度下室内温度可稳定在20℃左右;室外温度10℃时系统COP为4.25,室外温度-10℃的COP可以达到3.65;地板采暖系统的蓄热效果良好,室外温度0℃停机120 min后室内温度仍可维持在12℃以上。
The experimental platform of air source heat pump direct floor radiant heating system is built,and its heating effect,operation energy efficiency and thermal storage effect are experimentally studied.The results show that the heating effect of the new system is good,and the indoor temperature can be stable at about 20℃when the ambient temperature is above-10℃.When the outdoor temperature is 10℃,the system COP is 4.25,and when the outdoor temperature is-10℃,the COP can reach 3.65.At the same time,the thermal storage effect of the floor radiant heating system is good.The outdoor temperature is 0℃,and the indoor temperature can still be maintained above 12℃within 120 min after shutdown.
