Discussion on Operation Strategy of a Combined Radiant Ceiling and Displacement Ventilation System in Summer
摘要
Abstract
For the operation of combined radiant ceiling and displacement ventilation system in summer, the condensation on the surface of radiant ceiling and the slow response of temperature caused by the system' s big inertia are two key negative factors. Aiming at the two negative factors,the best operation strategy was searched after in this paper,and the field experiments was done in a villa project in shanghai. By analysis on the measured data,the feasibility of operation strategy was discussed. The results show that the strategy can avoid condensation on the surface of radiant ceiling effectively,and the temperature decreasing rate is closely related the parameters of the supply air. In addition, the switching node of stages should be judged according to practical situation.In conclusion, the strategy may be guidance of applying the combined radiant ceiling and displacement ventilation system.关键词
