(2) the selection and calculation of the equipment: according to the calculated heat and cold load, select the corresponding air conditioner equipment, such as fan coil, new air unit, air conditioning unit, fan and so on.

(3) air conditioning air system design: according to the demand of the air volume, select the corresponding wind pipe and the size of the wind pipe, and require the hydraulic calculation of the wind system, to ensure that the pressure of the unit is sufficient.

(4) the design of air conditioning water system: select the corresponding type of frozen water pipe, and the pipe diameter, and carry out hydraulic calculation to ensure the hydraulic head to meet the requirements and hydraulic balance.

(5) air flow calculation and CFD simulation.

2 main contents of the design

（1） air conditioning design

The design area is pided into different air conditioning areas, in which the auxiliary rooms are equipped with fan coil and independent new air system, the fan coil unit is selected with beautiful equipment, and the new wind unit is selected as the hoisting type new wind unit of Shandong Qingyun air conditioning plant. The natatorium, the badminton hall and the atrium all adopt the whole air system. Because of its great difference in function, the three rooms use independent air handling units, and the unit selects the beautiful commercial MKZS series air handling units.

（2）ventilation system design

The mechanical ventilation system is set up according to the requirements of the bathroom and bathroom. In this design, the fans of the fan are all selected from the fan, with metal soft takeover, the outside wall of the insect proof and rain prevention, and the stop device.

3. design emphasis

The key points of HVAC design lie in the air conditioning pision, air conditioning form and reasonable air distribution in the building. This design pides the building into four areas: the first one is the auxiliary room area, the second is the tall atrium, the third is the swimming area, and the fourth is the badminton hall. The auxiliary function room area is different from the room function and the use time is different, so this area adopts fan coil and independent fresh air area. The advantage of this system is that it can meet the different load needs of each room well. The large atrium adopts the air conditioning system, only the temperature of the personnel area can be controlled, the other areas can not be controlled to form a clear vertical thermal stratification, so the advantage of the design is that it can save energy. The natatorium area uses an independent whole air system. The swimming pool has a large humidity and high chlorine content in the air, so it must adopt an independent air conditioning system. The badminton hall adopts the independent whole air system, the air flow organization adopts the way of sending back and back, it also forms the vertical thermal stratification, only controls the personnel area and saves energy.

This project is designed according to the above description, and the design results are independently completed under the guidance of my tutor.
