The high-level architecture is one student dormitory.This design content mainly includes the classroom and dormitory heating design and the basement and smoke stairwells fire smoke design。The total construction area of ??34856.64m2, load 428.4kw. Design includes design of the aerial parts of the heating, basement and whole building design smoke ventilation. Heating methods for the radiant floor heating system under the form of different programs for the next time the system. Extension of a central heating part of a network, the original director Qiduan Road from North Street J0 point, westward along the small East Street, then north through Eastern Ring Road, then west from the district heat export two, into the heating station. The total heating area of ??150,000 square meters, diameter of DN200.The total length of the pipeline 519m. For the return water temperature is 130/70 ℃, the design pressure of 1.6Mpa. The total thermal station area of ??150,000 square meters of heating, heating load 7.5MW. This design uses a net return to fill the second network, a water temperature of water, the design water temperature of 130 ℃, return water temperature is 70 ℃; secondary water for the low-temperature water, the design water temperature is 85 ℃, return water temperature 60 ℃. 朗读显示对应的拉丁字符的拼音? 字典 朗读 显示对应的拉丁字符的拼音 ? 字典 Keywords: design issue
