地板辐射与新风制冷综合实验室设计及蓄冷研究

Design of Floor Radiation and Fresh Air Refrigeration Comprehensive Laboratory and Research on Cold Storage

文中介绍了地板辐射与新风制冷综合实验平台的搭建方法和其所能实现的功能,并以实验的方式对混凝土结构辐射地板的蓄冷性能进行研究,得出供水温度对蓄冷性能影响较大,供水温度越低,蓄冷量越大;不同供水温度下,地板蓄冷量达到饱和状态所需时间基本相同;地板辐射供冷系统对室温控制存在滞后性,供水温度越高,滞后越明显.

This paper introduces the building method and the functions of the comprehensive experimental platform of floor radiation and fresh air coupling refrigeration,and studies the cold storage performance of concrete structure radiant floor by experiment.It is concluded that the water supply temperature has a great influence on the cold storage performance.The lower the water supply temperature is,the greater the cold storage capacity will be;under different water supply temperatures,the floor cold storage capacity needs to be the same to reach saturation state time;The floor radiant cooling system has hysteresis in room temperature control,and the higher the water supply temperature,the more obvious of the hysteresis.
