  1. Energy consumption of heating rooms will increase when air exchange rate become large. because the mechanisms of heating methods used currently, such as radiator heating, ceiling heating and warm - air heating, are different from each - other, the indoor thermal environment is not the same when each one of them employed for room heating. for enhancing energy efficiency of heating rooms, indoor thermal comfort and energy saving effects should be investigated when natural ventilation is used to make a good air quality indoors

    房間的增加勢必導致供暖房間能耗加大,頂棚輻射、散熱器和熱等三種採暖方式由於供暖機理不同,形成的室內熱環境特徵不同,時產生的熱損失也有所區別,為了提高大量房間的供暖節能效果,必須對不同供暖方式在大量情況下的熱舒適性與節能效應進行研究。
  2. The experimental results indicate that when the air flow rate is determined, the key problem for energy saving is how to keep the indoor thermal comfort at a suitable level and reduce the difference between the internal and external temperature of the room. a formula is gained for calculating the critical values of air exchange rate. when ventilating rate is greater than the value, radiating heating is the better way for energy saving, or else, convection method in heating is more suitable

    實測還指出,當量一定時,如何保證人體熱舒適度不變而減少室內外溫差將成為大量房間節約採暖能耗的關鍵,本文結合圍護結構傳熱機理,在對三種方式的能耗狀況進行理論分析的基礎上,提出了的節能臨界值,若高於此值,則輻射供暖是較好的選擇,否則,散熱器供暖是較好的方法。
