2 The general situation of the engineering
This project is the air-conditioning for the Five-star hotel in Guangzhou. The total construction area of 23639 square meters. 21.731 meters high.
Hotel is a large number of public places, temperature, humidity, cleanliness and fresh air volume, a great impact, hotel guests and staff. Dirty dust-laden air is easy to spread certain diseases. Therefore, the air environment is getting the attention of the commercial sector. Add a ventilation and air-conditioning systems in hotels, welcomed by the majority of tourists. According to statistics, some hotels in the same city at the same lot, Where the good ventilation and air conditioning systems, and its annual turnover is much larger than similar-scale hotel, and the hotel staff's working environment has been better improve work efficiency , reduced sick personnel, attendance increased.
3 The basic of Design
Hangzhou weather:
Atmospheric pressure: Winter 100.45 Kp, the summer: 101.95 Kp.
Outdoor air parameters: the summer dry bulb temperature: 33.5 ℃
Outdoor summer air-conditioning calculated wet bulb temperature: 27.7 ℃,
Winter dry bulb temperature: 5℃
Outdoor ventilation design parameters
Summer dry bulb temperature: 31 ℃ winter dry bulb temperature: 13 ℃
4 The main design work
Choice of architectural features of air-conditioning; cold and heat load calculation; wind of a water pipe layout, hydraulic calculation; breakdown of the water pipeline computation. Hydraulic calculation based on choice of air-conditioning, including air conditioning units, the new wind generating units, fan coil, outlet and other equipment.
5 Air-conditioning system of choice
According to room function, building to three court part of the whole air should be used a return air system, this system is easy to use to play the advantages of energy saving, investment and savings in the large space. To the second floor of the surrounding part of the all-water system, inpidually controlled fan coil, due to the structural design characteristics of the building itself, so the whole water system will not lead to lack of fresh air.
6 Ventilation and smoke control
The ventilation and air conditioning system works by each horizontal fire zone settings. Pipeline use of non-burning material, insulation, noise reduction materials of non-burning material or material difficult to burn. Wind not normally pass through the firewall, settlement joint, and joints. Exhaust pipe to prevent a return measures. Air-conditioning systems, exhaust gas generated by the buoyancy, pressing or other natural forces of the flue gas from the outside, the main use of windows, balconies, or exclusive discharges, such as vertical shafts will be discharged gas concentration or dilution gas, which is natural smoke. Benefits: simple facilities, less investment, less routine maintenance work, easy to use.
The project room toilet located mechanical ventilation devices, set exhausting-fan, the ventilation of toilet by 20-30 m3 / h. Windowless bathroom set up exhaust-opening, exhaust duct from the same access to, from exhaust to the outdoors-row. And around the external walls and windows of a bathroom, directly into the outdoors. Toilet maintain negative pressure to prevent the leakage of odors and toilet optional and exhausting-fan check valve.
