Second ,the type to determine the structure of the air conditioning system, according to the design of a building itself, through the study of the characteristics of all kinds of air conditioning system selected architecture of central air conditioning system. Common air conditioning system for office buildings are the central air
According to the given design parameters and calculated parameters, find the appropriate data manual for the system of hydraulic calculations, hydraulic calculations, according to already draw system sketch, determine the system's most unfavorable pipe, mark the most unfavorable pipe node , by assuming the hydraulic sub-flow method calculations on the diameter of the pipe and the piping of the hydraulic losses, hydraulic loss for pipe larger diameter pipe to adjust, come to a reasonable total water along the way loss. Based on the calculated hydraulic losses along the way, a reasonable estimate of the share of local head loss, determine the total water loss, according to a variety of equipment selection formula is calculated for selected machinery, pumps and fans to determine the appropriate model. Excel summary data compiled in tabular form.
In addition to consider the processing of the entire system of water quality, set up according to specifications and requirements of water treatment equipment, including softening water tank, automatic dosing barrels and hydrating water supply equipment, etc. According to the above design and calculation of indoor air conditioning wind pipe drawing plan, floor plan of the plan of the ventilation system, water system and the system diagram.
The main task of the design is to complete this building cooling load calculation; demonstration of air-conditioning system and selection of cold-water unit; the design of cooling the engine room; and drew layout of the wind, layout of the water, Layout of the engine room and water system axonometric map of 8storey.
Through the scheme comparison,on the base of cooling load, heating load and moisture load calculation, primary air fan-coil system is adopted by way of technical and economic analysis. Every storey set of new wind generating units singly to ensure that indoor humidity and the requirements of the amount of fresh air. The chilled water which is a closed two-pipe direct return water system is supplied by the refrigerating plant room. Measures of noise elimination, damp, fire prevention and insulation is considered during the design.
The design includes the classification of air conditioning system, the calculation of cooling load, the selection of air-conditioning equipments, collocation and hydraulic calculation of air duct and water pipe, the calculation of air distribution, noise reduction,vibration isolation and insulation of air conditioning system ,the design of refrigerating plant room and the selection of water pump and so on.
