The development of radiant floor cooling system (RFCS): System type, control strategy, and application

Abstract

The utilization of radiant floor systems is one effective method to address the increasing cooling demand. The radiant floor cooling system (RFCS) has self-regulating capabilities, which benefit grid stability and the use of renewable energy. The application performance of RFCS is based on system design and intelligent control, as systems with high thermal inertia make it difficult to provide ideal indoor response effects. Therefore, this review aims to summarize the current development status of RFCSs and evaluate future development directions based on relevant research trends. A comprehensive overview of the radiant floor structure and the composition of RFCS were provided. The type of radiant floor structures can bring greater possibilities for the application of RFCS. Then, system control and evaluation are analyzed, with research on anti-condensation of radiant floors mainly focused on system and environmental control. Based on application status of the RFCS, the impact of various factors is discussed, including condensation risks, and climate change. Resistance to disturbances not only requires implementing control measures but also integrating with the building environment. There is still great potential for the hardware design and multi-directional integration of RFCS. The results of this review help relevant researchers gain a comprehensive understanding of the current development status and prospects of RFCS contributing to the decarbonization of the construction industry.
