Probability Method Applied To Detemine Hot Water SupplyDesign Second Flow Inside Of Buildings

The methods of deciding water and hot watersupply design second flow imside of buildings include square root method, experience method and probability method. The design second flow formula in our country is used in the Sovia union before. But the Sovia used the probability method in the 1960s.The hot water and the watersupply second flow formula is the same in the existing criterion. But the veicle, the law, the time and the probability that the people using hot water is deflSrent from that of the water. So it should have a method.Many experts and designers hold that the design flow provided by the normal formal is a lot of lack, Everybody consistently thinks that the probability method is reasonable and viable in calculating the water supply by many expert, scholar, professor's research.The paper presents a new method of calculation formula based on probability method with studying the Hunter'method and Russian method deeply. The principle is that making use of the foreign theories, at the same time, considering comprehensively the influencing factor of using water and using the parameter as few as possible and relating characteristic of using water with the our country's fact, gain a new method that is applicable to our country various building and simple inpractice. Main contents for studying of the paper is:(1) Analysing the outcome, characteristic and the problem of the hot water supplydesign second flow method in the Europe and the USA.(2) It is determined that value frequenly of different fixture use in the period of using water high peak.(3) The relation between the N and the hot watersupply design second flow is got by applying program to computer under the different probablity.(4) Form the realation between the qg and the N, P.(5) Drawing the chart about the hot watersupply design second flow in the <>...
