Hotel HVAC design and construction drawings
Design description: building function: hotel height category: high-rise building building area: 15000 ㎡ Number of floors above ground: 14 floors underground: 1 floor Drawing depth: number of construction drawings: 16 Design content: air conditioning, ventilation, smoke control, cold and heat sources: lithium bromide absorption unit Air conditioning system: all air system, air water system: constant flow, double pipe system, same procedure, Different air supply mode: detailed drawing of side air supply node: brief introduction of cooling tower This project is a hotel, with 14 floors above ground and 1 floor underground; The basement is the warehouse and equipment room, the first floor is the bath area, hall, kitchen, banquet hall, etc., the second floor is the bath area and dining room private room, large dining room and kitchen, the third floor is the multi-function hall, sauna private room and conference room, and the fourth to fourteenth floors are the guest room standard rooms, with a building area of about 15000 square meters. Design scope: central air conditioning and ventilation engineering design from the first floor to the 14th floor, basement smoke control engineering design, central air conditioning refrigerator room engineering design, staircase and front room pressurized air supply and smoke control design. Air conditioning system: the cooling load of air conditioning in this project is QL=1740KW, and the heating load of air conditioning is Qr=1500KW. The air-conditioning water system of this project adopts a double pipe system, in which the riser of system B is the same process as the down supply and down return, and the horizontal main pipe is the same process. The vertical pipe of system A is the upper supply and the lower return process, and the horizontal main pipe is the different process. The air conditioning system of fan coil unit plus fresh air is adopted for each floor of the air conditioner. The air conditioning fresh air system adopts a low-speed air duct air system. According to the different suspended ceilings, the air distribution adopts up supply and up return or side supply and up return. The air supply outlet adopts a double-layer louver air supply outlet, and the air return outlet adopts a single-layer louver air return outlet. In order to achieve the purpose of energy conservation, the air-conditioning side water system of the project adopts constant flow control, the water pipes of fan coil units and fresh air units are equipped with gate valves, and the fan coil units in the room are controlled by temperature controllers. Ventilation and smoke control system design: public toilets are equipped with room ventilators to meet the air exchange rate of>8 times/h. BLD-300 room ventilators are selected in the toilets and connected to the shaft with hoses System design of central air conditioning refrigerating machine room: two steam lithium bromide absorption refrigerating units are selected as the refrigerating unit, with a single refrigerating capacity of 872KW, and the supply and return temperature of chilled water is 7~12 ℃. The chilled water system of the air conditioning uses a digital constant pressure unit, and the chilled water is replenished into the water system by a make-up pump after being softened. For the cooling water system of air conditioning, an electronic water treatment device is set at the inlet side of the unit. Air conditioning heating is realized by two steam water heat exchangers 17 drawings.
