Therefore, we should understand that the direction of the fresh air exchanger should consider the size of the unit, piping layout, and meet the requirements of safe travel. Air conditioning unit and fresh air unit are commonly used and installed with fan box. Although there are differences between fresh air unit and air conditioner, they can complement each other in function. It is suggested that fresh air units should be installed at the same time, and then fan coil units should be installed in each room to learn from each other to achieve the purpose of more energy saving and comfort.
When the ceiling type fresh air fan is installed outside the window, it is necessary to build a covered unit to avoid the damage of wind, sun, rain and dust on the fan. The fresh air unit control includes: supply air temperature control, air supply relative humidity control, antifreeze control, CO2 concentration control and various interlocking. If fresh air unit (such as DC fan) is considered to bear indoor load, indoor temperature (or indoor relative humidity) should also be controlled. A structure that does not cause dustpan.
Air space for installation of fresh air exchanger:
It can be safe. In order to make the new trend of ceiling type handle affairs, convenient maintenance and do not stop the working nature of the machine, the installation position of the fresh air fan must be away from the sky to meet the requirement of more than 80 cm of air, and consider (consider) the filter (role: filter impurities, etc.) and heat removal equipment, fan maintenance and keep healthy. When the air flow into the box, avoid eddy current (also known as Foucault current).
