The proposals of bigger temperature difference with lower water flow rate and variable primary water flow rate were introduced to reduce the operation cost or primary cost of chilled water system 摘要详细分析了大温差小流量系统方案和一次泵变流量系统方案在空调水系统节能方面的异同。
The country has adopted a policy of low - volume , high - cost for tourism , which is intended to facilitate protection of the fragile natural environment and stimulate sustainable tourism development 这个国家对旅游业采取了小流量、高成本的政策,旨在促进保护脆弱的自然环境,推动旅游业的可持续发展。
In order to overcome those defects , we chose the fluid oscillation characteristics of vortex type fluid oscillatory flowmeter as research subject on the basis of the former achievement 本论文针对旋涡型流体振动流量计小流量信噪比低和抗干扰性能差等问题,确定以流体振动特性应用基础为主要方向。
Cw the feature of cw magnetic - driving vortex pumps is little capacity , high - head , it can convey the fluid containing 20 percent of gas and non - lubricative , also can be used to the occasion where npsh is low Cw型磁传动旋涡泵,是小流量高扬程应用最理想的选择;可输送含有20 %气体的介质,可应用于非润滑性流体和汽蚀余量很低的场合。
However , it has unsolved disadvantages up to present time , such as poor noise immunity in low flux , low interference immunity and adhesion of the sensor surface that affects the meter sensitivity 但是这类流量计存在的三大缺陷,至今没有得到很好解决:小流量信噪比低,抗干扰性能差,传感器表面粘滞对检测灵敏度的负面影响。
