Discussion on the Harm and Protection of Water Hammer of Cavities Collapsing during Long Distance Water Transfer Project Li Zhao1,2,a and Yudong Lu1,b 1School of Environmental Science and Engineering, Key Laboratory of Environmental Protection ＆Pollution and Remediation of Water and Soil of Shaanxi Province, Chang’an University, Xi’an 710054, China 2Department of Power Engineering, Xi’an Aeronautical University, Xi’an 710077, China azhaoli200817@163.com,b1332875233@qq.com Keywords: long distance water transfer project; water hammer of cavities collapsing; two-way surge tower; constant speed buffer air valve Abstract.
Pipeline engineering can not be completely sealed, more likely to produce air cavity.
The water column separation of hydraulic transient process in pumping station pipeline system and the ensuing water hammer of cavities collapsing(hammer cavity collapse), which is harm to long distance pipeline engineering and various industrial pipelines ,which is huge and amazing.
After a large number of engineering practices testing, prove this scheme has good protection effect.

Application analysis of the recovery fresh air heat pump units in energy saving reform of air conditioning in the severe cold regions Aoxue Chen1, a, Zhao Chen1,b , Chunyu Ran1,c and Chunqing Wang1,d 1School of Municipal & Environmental Engineering,Jilin Jianzhu University,Changchun, P.R.China achenaoxue2002@163.com, b274777737@qq.com, cranchunyu@hotmail.com, dwangchunqing@hotmail.com Keywords: the severe cold regions; the recovery fresh air heat pump units;regression analysis.
In order to ensure the indoor air quality, air conditioning system will introduce a large number of fresh air,the majority of indoor air will be discharged, it will take a lot of energy, therefore,the study of exhaust air heat recovery in air conditioning system has a significant meaning for energy saving of air conditioning system.Concerning to study on exhaust air heat recovery technology, Wu Yiping of University of South China[2], they proposed to analyze the energy-saving of air source heat pump based on exhaust air of air-conditioning system.They obtained that it can greatly improve the performance parameters of air source heat pump when they considered the exhaust air of air conditioning system as the low temperature heat source, and analyze its energy saving.College of civil engineering, Hunan University, Yang Guang, Tang Guangfa, Guo Yanjie, Liu Di, Lu Jilong [3], they study the feasibility of small heat recovery device, through recovery the waste heat to preheating or precooling
This article will introduce the recovery fresh air heat pump units, and compared with the traditional air units, it was analyzed based on the measured data, summarizes the technical parameters for guiding practical engineering application, and provides the optimized scheme.
Heating load of recovery fresh air heat pump in testing period and original air conditioning system Regression analysis model According to the operation principle of recovery fresh air heat pump units, system recycles exhaust air heating to preheat the outdoor air, it can find the relationship between exhaust air temperature and preheating temperature, use the regression analysis theory of mathematical statistics to find out the relationship between the two temperature, summarize the technical parameters for the practical engineering application, provides reference for the related engineering application.
In the general engineering applications, the correlation coefficient R between the predicted and actual value which reached 0.75 or more is effective forecast, it has the guidance meaning on control strategy.
