By the calculated total load, to determine the form of systems, this design, I will layer, layer by layer, and 10 unified district water system; layer 3-11 rooms pided into two area water system, using fans coil plus fresh way. Combining the characteristics of the building, in the chilled water system to determine the choice I closed, vertical differentiation process, double-control, single-stage pump, variable flow system, this air conditioning system has a simple structure, the initial investment is small, difficult to produce pipeline dirt and corrosion, the advantages of smaller pump power. Design will be air-conditioned room set at the top, deal with air-cooled, air conditioning units model is MTD-50S/E. This design is that a good reduction of the boiler room to meet the requirements of the premise makes the design tends to simplify.
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.
Fan coil, water pumps and ancillary equipment such as equipment selection and determine the model calculation. According to the design conditions and the total cooling, heat load and the design have been identified, equipment form, select the air duct and the terminal equipment, cold and heat source equipment. Selection based on different levels in different functional requirements of the new wind load, the layer of fresh air unit model is BFP-2 and BFP-8 . Fan coil in this design I chose computing models, mainly FP-8WA、FP-5WA and FP-6.3WA.。
