Numerical Investigation Of A Diffuse Ventilation Ceiling System For Buildings With Natural And Hybrid Ventilation, Alessandro Nocente, Francesco Goia, Steinar Grynning

International Building Physics Conference

The need to meet requirements, both in terms of ventilation and thermal comfort in modern buildings, has led to the development of different concepts for ventilation, among which the so-called Diffuse Ceiling Ventilation (DCV). This system makes use of the space between the ceiling slabs and the suspended ceiling as a plenum for fresh air, while the suspended ceiling itself becomes an air diffuser element. If compared to traditional solutions, this allows a higher amount of ventilation air to be injected in the room at lower speed, and a more even distribution of the fresh air within the room. Furthermore ...


Numerical Analysis Of The Influencing Factors On The Performance Of A Pipe-Embedded Window Operated In Summer, Sihang Jiang, Chong Shen, Xianting Li Sep 2018

Numerical Analysis Of The Influencing Factors On The Performance Of A Pipe-Embedded Window Operated In Summer, Sihang Jiang, Chong Shen, Xianting Li

International Building Physics Conference

The pipe-embedded window is a double window structure with pipes embedded inside the cavity to adjust the temperature. The preliminary studies showed that it can significantly reduce the cooling load of buildings with natural cooling sources such as the water from cooling towers in summer. However, the research on the influencing factors of the pipeembedded window is insufficient. In this paper, the numerical calculation models are established for a pipe-embedded window and a traditional window. The influence of climatic factors, such as the natural cooling source temperature and outdoor air temperature on the thermal performance of the pipe-embedded window are ...
