In Korea, radiant floor heating systems are commonly used in residential buildings, even high-rise houses. If these existing radiant floor heating panels could be used for cooling as well, additional benefits beyond the basic advantages of radiant heating and cooling systems in terms of energy efficiency and comfort level could be conferred upon the homeowner, such as avoiding redundant investments for both heating and cooling equipment, and reducing the area occupied by the equipment. However, the comfort requirement of floor surface temperature has to be satisfied, because the human body comes in direct contact with the floor surface. In addition, dehumidification equipment is required to remove the latent load and to prevent surface condensation. It may be particularly difficult to apply such a system in high-rise residential buildings with massive concrete slabs as compared to light-weight buildings, because of the complexity of the system configuration and the thermal capacity of the building structure. In this study, the feasibility of radiant floor cooling systems (RFCS) for residential buildings with massive concrete slabs was evaluated. The strategy for the configuration and arrangement of an RFCS was based on the current configuration of the heating and cooling system as well as the cooling load. Then, through field testing, the performance of this system for cooling and condensation prevention was evaluated along with the occupants’ characteristics for adjusting parameters related to thermal comfort. As a result, an RFCS combined with supplementary equipment for dehumidification and cooling would satisfy the requirements for cooling and condensation prevention in a residential house with multi-zones.

在湿热气候条件下大体积混凝土板住宅楼辐射地板冷却系统的可行性

在韩国，地板辐射采暖系统普遍用于住宅建筑，甚至高层住宅。如果这些现有的地板辐射采暖板也可以用于制冷，除了辐射采暖和制冷系统在能源效率和舒适度方面的基本优势之外，还可以为房主带来额外的好处，例如避免对供暖进行多余的投资和冷却设备，减少设备占用面积。但是，由于人体与地板表面直接接触，因此必须满足地板表面温度的舒适度要求。此外，还需要除湿设备以去除潜在负载并防止表面冷凝。由于系统配置的复杂性和建筑结构的热容量，与轻型建筑相比，在具有大量混凝土板的高层住宅建筑中应用这种系统可能特别困难。在这项研究中，评估了地板辐射冷却系统 (RFCS) 在具有大体积混凝土板的住宅建筑中的可行性。RFCS 的配置和布置策略基于加热和冷却系统的当前配置以及冷却负载。然后，通过现场测试，评估了该系统的冷却和防冷凝性能以及居住者调整与热舒适相关参数的特性。因此，
