The new building has a total construction area of ​​17,000 square meters, with a total of 15 floors. The 1 to 3 floor podiums are public facilities such as shopping malls, restaurants and entertainment. The 4th floor is a senior office and the 5th to 15th floors are rooms. The 1 to 3 floor podium part adopts the all-air low-speed air conditioning system, and the 4-15 floors office and guest rooms adopt the fan coil and fresh air system. There are 3 variable air volume units on the 1st to 3rd floors and 216 fan coils on the 4th to 15th floors. Air-conditioning control mode, control of air-conditioning units in all-air low-speed air-conditioning system For public places with large changes in the load of the podium, the all-air low-speed air-conditioning system is more suitable, which makes the fresh air operation possible, not only guarantees the indoor sanitary standard. And can achieve the purpose of energy-saving operation. The air supply volume of the air conditioning unit is controlled, and the fresh air volume is controlled by the carbon dioxide concentration of the room to be adjusted. In each room of the air conditioning system, there is a temperature and carbon dioxide concentration sensor (the sensor can also be placed in the return air duct), the new air volume is controlled by the carbon dioxide concentration of the room being adjusted, and the temperature of the room is controlled by the frequency converter. The frequency thus controls the air supply volume of the air conditioning unit, while the water flow rate of the air conditioning unit remains unchanged, so that the carbon dioxide content of the room to be adjusted is controlled to be less than 0.1%. A solenoid valve is arranged in the water passage of the unit, and is linked with the fan. When the fan starts, the solenoid valve is opened, and the solenoid valve is closed when the fan is stopped.
