- Abstract
To study the heat transfer characteristics, indoor thermal environment construction and energy consumption of the lightweight radiant floor heating (LRFH) system with non-full-coverage heat-conducting plate, the LRFH system and the traditional radiant floor heating system (TRFH) under different operating conditions are compared and studied by using the field experiment and theoretical calculation method. The results show that the air temperature in the main activity area of the LRFH system rises from 5 °C to 15 °C for about 2 h faster than that in the TRFH system, and compared with the TRFH system, it takes about 5 h for the unsatisfactory percentage of indoor prediction to decrease to 20%, but only about 2. 2 h for the LRFH system. Meanwhile, the LRFH system saves about 15% to 17% energy compared with the TRFH system, which may be related to the proportion of effective heat transfer at the end. In addition, the LRFH system intermittent operation of indoor air temperature control is more stable, but the maximum temperature rise of the air in the main activity area of indoor personnel is 3. 3 to 3. 6 °C lower than that of the TRFH system, and there is a large temperature difference on the ground. The study can provide a reference for the design and application of the lightweight radiant floor heating and cooling systems.
