STUDIES ON THERMAL COMFORT AND ENERGY CONSUMPTION OF HVAC SYSTEM

摘要

There is a close relation between the thermal comfort and the energy consumption of HVAC system. Based on the analyzing of the relation between the thermal comfort and the energy consumption of HVAC system, the experiments of the thermal sensation of students were carried out at different relative humidity with different temperatures, respectively 25%, 50% and 75%. The effects of the temperature and the relative humidity on the thermal comfort were obtained after statistically analyzing experimental data. The results show that changing the relative humidity almost has no effect on the thermal comfort in the surveyed students. The results also show that changing the relative humidity has a greater effect on the energy consumption of HVAC system than that of changing temperature. So the energy saving of HVAC system and a suitable thermal environment can reach a good harmony.
