Abstract
In Hot–Summer and Cold–Winter (HSCW) areas, with the improvement of social economy and people's living quality requirements, most residents are installing radiator and floor heating equipment to meet the heating demand. To explore the thermal comfort difference of different heating terminals and their adaptability in HSCW areas, the thermal environment parameters created by different heating terminals and the energy consumption of the heating system were measured in the laboratory, and the thermal comfort, thermal feeling, and physiological parameters of the subjects were investigated. Results showed that under the same energy consumption, the indoor temperature distribution of Floor Heating (FH) was more uniform, which can better meet the needs of the comfort of the feet and legs of the subjects. Using radiator heating (RH), the comfort of the subjects at different distances from the end had obvious differences, and the improvement effect was not good when the indoor heating temperature rises. The actual test finds that with the increase of indoor temperature, the energy consumption of RH exceeded that of FH. The operating cost of FH is lower, and the actual benefit and economy are higher in the HSCW areas where central heating is lacking. FH has better comfort and economic benefits in HSCW areas. The research provides suggestions and reference for residents to choose heating terminals in winter.
