The following is the design idea of this design:
The majority of the hotel rooms are in the morning 6 to 12 in the evening, depending on the guest's needs. The rooms may include television sets, computers, hair dryer and other equipment, while some electronic equipment may be full-time work. Therefore, the economic air-conditioning design, should be in the design of the room before the assessment.
Lighting load is part of the whole load of the hotel.. The average load of the lighting and general electrical equipment in 10 to 50w/ square meters, but probably will be much higher, according to the grade of room to decide.
General lighting can be discharged through the exhaust heat or return device, so as to achieve the purpose of regulating the air. Then through a pipeline connecting each device although it can achieve the air system to maintain a balance, but the cost is relatively high, it is recommended that the return air, the air natural convection, energy saving and environmental protection.
Because of the progress of the society and the rapid development of economy, the ecological environment is becoming more and more serious.. People pay more attention to energy saving and environmental protection, pay attention to sustainable development. Central air-conditioning system is a huge and responsible system, energy consumption is huge, so there is a lot of space can be energy saving. In the design of the process also considered the issue of energy saving, so each link is strictly in accordance with the national, regional or industry standards and norms of implementation.
2, smoke control system design:
According to the characteristics of the buildings and the relevant specifications, the use of mechanical pressurized air way.
Smoke is provided in the corridor, and the evacuation route and the refuge of the smoke interfere with the fire is provided in the event of the fire.. Through the air supply air, air duct section area, resistance and other calculation, determine the wind turbine model.
The smoke extraction is the delay can be discharged through the smoke evacuation, which can provide the evacuation and the fire rescue.. By the partition of the scheme, the calculation of the window area is determined, and the mechanical ventilation is used in the corridor.. The model of the exhaust fan is determined by the calculation of the smoke quantity, the area of the smoke, the smoke pipe and the resistance..
