According to the given design parameters and calculate the parameters, find the appropriate data manual, carries on the system of the hydraulic calculation, in the hydraulic calculation, according to have draw sketch system, determine the most unfavorable section, with the most disadvantageous section node, and USES the assumption that the hydraulic calculation of flow velocity method section, it is concluded that the pipeline diameter and hydraulic loss of the entire pipeline, pipe diameter adjustment for pipeline section of hydraulic loss is larger, along a reasonable total hydraulic loss. According to the calculated along the Cheng Shuili losses, reasonably estimate the share of local head loss, determine the total hydraulic loss, according to the calculation formula of all kinds of equipment type selection, after calculating the selected hydraulic machinery, determine the right type of pump and fan. Into excel spreadsheet data gathered will form.
Fan coil units, water pumps and accessories selection calculation and determine the type of the equipment. According to the given design conditions as well as the total cold, heat load and has identified form of design, equipment, selection of air duct and terminal equipment, cold and heat source equipment, etc.
In the fresh air in the design of the entrance with fixed waterproof shutter, in case of the rain in. In according to the actual situation of building, the hall adopts lateral supply airflow organization form, and selects the double shutter inlet; Airflow organization adopt the way of sending last time; Return air duct are on the ceiling is decorated, such arrangement can reduce capital investment are the benefits of air duct, and occupy a building area of large, decorate coordination easier.
This design content includes: air conditioning cold heat load calculation; The determination of air conditioning system and argument; The determination of supply air state parameters and delivery; Air handling equipment selection; The choice of cold and heat source and equipment type selection; Airflow organization; Hydraulic calculation. Other equipment choice; Heat preservation, vibration damping and noise elimination, etc.
Air conditioning system design is applied to the hotel building, must according to the characteristics of the building, make it accord with the temperature, wind speed, humidity, and people's comfort, is advantageous to the staff can work more efficient. So fully consider the reasonable air distribution, temperature and humidity and pressure control and energy saving measures, make a design more reasonable, more in line with the national standard.
