HVAC (Heating, Ventilation, and Air Conditioning) ventilation is not just a luxury but a necessity in any building environment.

What is the difference between a duct fan and a central air conditioner? Which one is suitable for home use?

The general comfort air-conditioning cold water supply/return temperature is 7℃/12℃. Hot water supply / return water temperature of 60 ℃ / 50 ℃.

Third, the precautions to be taken in the construction
1, prefabrication should pay attention to several issues

In the ventilation project, the air duct production should be based on the project requirements of the selection of suitable materials for the air duct. Design and construction personnel, need to fully understand the different material properties of the duct and they can be used, application occasions, and in what circumstances need to duct insulation, so as to build a set of reasonable and durable ventilation duct network system.

When it comes to air supply system and smoke exhaust system, the figure of stainless steel ventilation duct is indispensable. When using positive pressure air supply fan and fire exhaust fan, the duct is needed to play a temporary retention role for these winds, and then the wind will be successfully discharged or introduced to the position where it should be.

3. Fan coil + fresh air conditioning system
2) Air treatment process of fan coil + fresh air conditioning system
The fresh air and the fan coil each supply air to the air-conditioned rooms. In this way, even if the fan coil unit stops operating, the fresh air will remain unchanged.

Air-conditioning systems generally consist of air-handling equipment and air-conveying ducts, as well as air-distributing devices. According to the need, it can be composed of many different forms of systems.

Step 11: Design of air-conditioning equipment and its piping for cold-keeping and heat preservation, muffling and vibration isolation
