How to design villa central air conditioning

Shanghai air conditioning design villa air conditioning design:

1. Calculation of central air-conditioning load for villas: Before central air-conditioning is installed, the required load needs to be calculated, so that the machine can be selected according to the load. For houses and other rooms where the load of the enclosure structure is the main load, the intermittent load needs to be considered when calculating the load. The additional coefficient is 1.10—1.20, and the load caused by the temperature difference heat transfer in the adjacent room without air conditioning needs to be considered!

2. Selection and design of villa central air-conditioning system: For the determination of important air-conditioning systems, it is necessary to comprehensively consider the application site, use characteristics, and owner needs, and finally determine a suitable air-conditioning system!

3. Villa central air-conditioning piping design: In addition to the host and indoor units, the central air-conditioning piping is also an important part of the entire system. The piping design includes water pipe system design and air duct system design. In the water pipe system, the flow velocity of the main pipe should be below 1.2m/s, and the flow velocity of the branch pipe should be set at about 0.6m/s; for the air pipe, in order to reduce noise, the wind speed should be below 6m/s, and the branch pipe wind speed should not be higher than 4m/s. s, the wind speed of the sending and return air outlets should be 2m/s.
