The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...

Radiant ceiling cooling panels require an accurate and sensitive control system to avoid condensation; this is achieved by adjusting the temperature of radiant in adequate time. This study investigated a prediction model for dew-point attached air layer panels. When number position people indoors change, can predict change purpose panel time prevent condensation. The influence different factors...

The purpose of this study is to analyze the human response indoor climate with two individually controlled convective and radiant cooling systems: a low velocity unit combined panel system (LVRP) personalized ventilation (PVRP). As reference without individual control, diffuse ceiling (DCV-RP) was also studied. In laboratory conditions, 10 males females gave subjective during various office act...

Abstract Modular multifunctional building elements can overcome major disadvantages of the traditional sequential design and become prospective solutions for sustainable construction. Thus, this work explores lightweight glass fiber-reinforced polymer (GFRP) profiles capabilities as load-bearing slab modules in buildings. By adding water channels a cellular structure pultruded GFRP elements, hy...

In residential heat pump systems, the motivation for secondary loop systems is to allow for the use of flammable or toxic refrigerants with lower global warming potentials than the currently employed HFC refrigerants. The addition of radiant panels as integral building components (embedded in concrete at construction or attached to the underside of wood flooring) is becoming more common. Combin...
