General description of the design of the building is located in Kyrgyzstan, this project is an apartment building air-conditioning engineering design, floor height of about 44 meters, is a comprehensive building, with a total construction area of 7021 square meters, of which the air-conditioning area is 3165.2 square meters.
The main building of the apartment ground 11 floors, of which - floor for the dining room, conference room, lounge, the second floor for the office suite, conference room, three to eleven floors for single rooms, bedrooms, cadres room, the height of the floor are 4 meters. The indoor design requirements in this design refer to the comfort air conditioning indoor calculation parameters, preliminary design: summer: dry bulb temperature of 34.6 ℃ ℃, relative humidity of 69%, wind speed ≤ 0.3 m / s. Engineers according to the given building conditions for room numbering, determine the load type of the room, room size, door and window sizes, heat transfer coefficients of the enclosure, the room's orientation, the area of heat transfer, the outdoor air conditions, indoor design parameters. air strip conditions, interior design parameters. Calculate the hour-by-hour load statistics of each room with an excel spreadsheet, and determine the time when the maximum load occurs as well as the value of the maximum load. According to the requirements of energy-saving design standards, combined with the calculation software, the cold coefficient method was used to calculate the cold load of the whole apartment building hour by hour. After calculation, the total cold load of the apartment is 305.123KW, and the maximum load occurs at 17:00 p.m. From the calculated total load to determine the system form, in this design, we divide the first floor into the water system unified zone; the second floor is the water system layer; the 3-11th floor single room is divided into the water system of three districts, with the use of fan coils plus fresh air. Combined with the characteristics of the building, in the chilled water system to determine my choice of closed, vertical isochronous, dual-control, single-stage pump, variable flow system, this air-conditioning water system has a simple structure, the initial investment is small, the pipeline is not easy to produce dirt and corrosion, pumps consume less electricity and other advantages. The design of the air-conditioning room is set on the top floor, and Toshiba brand side outlet multi-connected + ducted inner unit. This design tends to simplify the design under the premise of meeting the requirements.
According to the given design parameters and calculated parameters, find the appropriate information manuals, hydraulic calculation of the system, in the hydraulic calculation according to the sketches of the system has been drawn to determine the most unfavorable pipe sections of the system, labeling the most unfavorable nodes of the pipe sections, the use of assumed flow rate method for the hydraulic calculation of the subsections, resulting in the entire pipeline diameter and the entire pipeline hydraulic loss, for the pipeline hydraulic loss of the pipeline diameter of the pipeline section is larger The pipe diameter is adjusted for pipe sections with large hydraulic losses to obtain a reasonable total hydraulic loss along the route. According to the calculated hydraulic loss along the course of a reasonable estimate of the share of local head loss, to determine the total hydraulic loss, according to the formula for the selection of a variety of equipment, selected after the calculation of hydraulic machinery, to determine the appropriate type of pumps and fans. The data will be summarized and prepared in the form of excel table.
Calculation and determination of model number for selection of equipment such as fan coils, pumps and ancillary equipment. According to the given design conditions as well as the total cooling and heating load and the already determined design scheme and equipment form, select air ducts as well as unterminated equipment, cold and heat source equipment, etc.
Apartment building pursuit of cost-effective, in the selection of models according to different layers, different functions of the required fresh air load, the selection of fresh air unit models are different, so the decorative effect is beautiful, with low cost, stable quality, power saving features. Congratulations to our company for successfully assisting Kyrgyzstan to take an apartment building supporting air conditioning project!
