变风量空调由于它显著的节能特性,在发达国家已普遍应用。这项技术在我国正在发展中,在设备研制生产和工程应用等方面都取得了可喜的成果。在应用和运行中也发现了某些急待解决的问题,其中直接影响使用效果的便是在低负荷状况下气流射程减短,造成室内温度、速度分布不均及“吹风感”,特别是在“侧送”时,情况更为严重。因主要的外围负荷,均发生在侧送风口对面,如果气流射程减短,将造成对面气流的停滞区,感到闷热。这些都直接阻碍了变风量空调的推广应用。为解决这一困难,我
VAV air conditioner has been widely used in developed countries because of its remarkable energy-saving characteristics. This technology is developing in our country and has achieved gratifying results in equipment development and engineering applications. In the application and operation also found some urgent issues to be solved, which directly affect the use of the effect is to reduce the air flow range under low load conditions, resulting in uneven temperature and speed distribution of the indoor and “hair blow”, especially The situation is even more serious when it comes to “side delivery.” Due to the main external load, they all occur opposite the side air intake. If the air flow is shortened, it will cause a stagnant area of the opposite air flow and become hot. These have directly hindered the application of VAV air conditioners. To solve this difficulty, I
