Research On Design Technology Of High Building Gas Supply

Urban nature gasnization is one of the realities which Shenzhen will face in the near future. With the commence of LNG project in Guangdong province, the gas source of Shenzhen began to transfer from LPG to nature gas. The use of gas in the building will become more popular and the design with regard of gas supply for high buildings will be more and more.The appearance of high building is necessary in the development of urban construction. High building can save the inadequate land and can form better city scenery. As one kind of clean energy, nature gas's use in the high building is very necessary. In public buildings, besides dining, the use of gas in air-conditioning, cooling and hot water supply is being rapidly developed.But the gas supply in high buildings has particularity which common buildings don't have. The problem of security is very abrupt. So the researches on design technique of high building gas supply is of great importance.This paper systematically introduced the principles and methods of design technique of high building gas supply. Detailed analysis and summaries on problems from buildings classification to special problems are given.Through systematical analysis and summarizing, several practical conclusions are gotten. That is we should pay much importance to the special requirements and probably led hidden troubles in the design of gas supply for high building, we should restrict this point in our design code. Hitherto there is no detailed code especially for high building gas supply in kinds of gas design codes.Currently only the overcoming of building sink, additional pressure and gas leakage alarming are primarily considered in the design of gas supply for high buildings. But researches on how to realize these techniques are still inadequate, for example, no good way to overcome the additional pressure exists.Internationally, in the design of gas supply for high buildings of many cities the elimination of irregular risks like earthquake is the object to be considered. However, the degree of importance paid to such problems isn't enough, especially ways for equipments treatment is very inadequate, we should pay special attention to it.
