Feasibility of a Radiant Floor Cooling System for Residential Buildings with Massive Concrete Slab in a Hot and Humid Climate

Phase change materials in thermally activated building systems: A comprehensive review

“…25 • The same hydronic system can be used for both heating and cooling modes, which reduces the capital investment. 26 • For large spaces with wide glass facades and skylights, RCSs (especially radiant floor ones) offer an additional advantage of direct absorption of short-wave solar irradiance, reducing its share of the overall cooling load of the space. 27 On the other hand, RHCSs have some inherent limitations constraining their wide adaptation, especially for RCSs.…”

“…The advantages and limitations of RCSs compared to all‐air systems are well‐established in the literature but not well‐quantified due to space, system, and outdoor climate factors affecting the performance of the system, as well as the costly experimental and numerical assessments. Recent examples of side‐by‐side comparison of these competing technologies can be found in Reference 26. Woolley et al 21 performed experimental comparisons between RCSs and all‐air cooling systems to study the heat extraction mechanisms and rates.…”

Experimental Study of Indoor Air Distribution and Thermal Environment in a Ceiling Cooling Room with Mixing Ventilation, Underfloor Air Distribution and Stratum Ventilation

“…Therefore, how to improve the energy efficiency of HVAC systems has become a hot research topic of scholars over the world [3][4][5]. At present, a radiant cooling system combined with a mechanical ventilation system has been widely used in various residential and nonresidential buildings [6,7]. Compared to the traditional air conditioning system, the radiant cooling system can more effectively deal with the external sensible cooling load by using the higher temperature cold source and avoiding the cold air draft [8][9][10], so it can meet the requirements of high thermal comfort level and large energy efficiency [11,12].…”

Dynamic prediction of the pre-dehumidification of a radiant floor cooling and displacement ventilation system based on computational fluid dynamics and a back-propagation neural network: A case study of an office room

“…Due to the use of this control method, the floor temperature was able to be maintained above 21°C, the surface dew was not formed, the vertical temperature difference was less than 1.9°C and the thermal comfort was good. Jeong et al 24 proposed a strategy for the configuration and arrangement of an RFC using an individual cooling source, which was derived for application to residential buildings in regions with a hot and humid summer climate, such as Korea. The results revealed that during most of the measurement period, the indoor temperature remained at the indoor set point temperature, and the floor surface temperature was higher than the indoor dew point temperature.…”
