Experiment on operating performance of radiant ceiling and displacement ventilation system in summer

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.
