Description
Technical field
The present invention relates to building installation engineering field, specifically a kind of dynamic design and calculation side of Environmental Control System of Metro
Method.
Background technique
Environmental Control System of Metro energy consumption accounts for about the 35%-45% of station total energy consumption, and system pipeline occupies the sky of the top more than 70%
Between, it has been largely fixed the scale and arrangement at station, has been the important content of subway Electromechanical Design.Environmental Control System of Metro
It is divided into 18h comfort air conditioning (a kind of room, manually put out), for 24 hours equipment air-conditioning (two class rooms, manually put out), for 24 hours equipment air-conditioning
(three classes room, extinction using gas), for 24 hours cold wind cooling-down air conditioner (four class rooms, extinction using gas), for 24 hours ventilation (five class rooms, manually
Put out), six subsystems of air draft for 24 hours (six class rooms, manually put out).There are about 65 rooms, these rooms at one coordinate quasi- station
Cross-distribution, it is mutually relevant, according to the difference for using function, adhere to different ring control subsystems separately, each subsystem calculating is determined
Due to external parameters such as environmental functional requirement, construction area, equipment heating, room staffings, and follow different calculating rule
Then.The environmental control system design of a usual standard station need to excessively be taken turns calculatings, about be related to a parameters up to a hundred, multiple systems overlap,
Calculate cumbersome, data are numerous, parameter intersect so that environmental control system dyscalculia.The multi-specialized intersection of Metro Design, each academic expertise
It conditions each other, the design cycle is long, and there are many uncertain factors, and with going deep into for design, condition constantly changes, any outer
The variation of portion's condition can all cause the variation of environmental control system.
Current environmental control system calculating relies primarily on manually, needs largely to be computed repeatedly, time-consuming and laborious, and can not be with
The variation of external condition modify immediately, easily cause mistakes and omissions, it is difficult to meet the requirement of timeliness and accuracy.Due to timeliness
With accuracy deficiency, environmental control system is determining equipment scale, when downstream profession proposes condition, can only rule of thumb estimate, error
It is larger, in order to contain uncertain factor, positivity bias is often artificially set, and deviation transmits amplification layer by layer, so that estimation result mistake
In guarding, it be easy to cause " four is big " problem that system civil engineering scale is big, place capacity is big, caliber is big, tail end air port is big.
Summary of the invention
The purpose of the present invention is to provide a kind of dynamic design approaches of Environmental Control System of Metro, utilize the function function of excel
Can, comparison design condition is automatically analyzed, partition sub-system loads every design conditions, design conditions and result is associated,
