【 摘 要 】

A transient simulation model of floor radiant heating system with air-to-water heat pumps for a 100 m2 building in the Beijing rural area was developed by using TRNSYS software, and combining the Hooke-Jeeves algorithm on the GenOpt platform, the influence of building exterior wall insulation on building heat storage strategy of the floor radiant heating system with air-to-water heat pumps was studied on the current peak and valley period electricity price. The law of the best heat-lag temperature and heat-lag time was obtained under different building exterior wall insulation method and thickness by optimizing the whole heating season operation cost.
