辐射吊顶+置换通风系统夏季运行性能实验研究
Experiment on operating performance of radiant ceiling and displacement ventilation system in summer
摘要：
以上海某栋别墅辐射吊顶+置换通风系统为研究对象，在夏季供冷工况下，从空气源热泵运行特性、风系统除湿特性、水系统运行特性、室内热舒适性、结露敏感性等方面对系统的运行特性进行了实验研究。结果表明，系统运行较稳定，在夏季可以实现较为舒适的室内热环境，但存在除湿能力差等问题。

Abstract：
Taking this System in a Shanghai villa as subject, experimentally studies the operating performance of the system in summer including the operating characteristics of the air-source heat pump and the water system, dehumidification characteristics of the air system, indoor thermal comfort and condensation sensitivity. The results show that this system can operate stably, and a good indoor thermal environment can be achieved in summer, but there are some deficiencies such as insufficient dehumidification capacity.
