In today's society, people's living environment is troubled to some extent. Smog weather seriously affects our daily travel, and people pay more and more attention to air problems. The fresh air system is gradually approaching everyone's field of vision. So how to choose a suitable fresh air system?
there are three types of domestic fresh air systems, namely, total heat exchange fresh air system, one-way fresh air system and ducted fresh air system.
The total heat exchange fresh air system has the function of heat recovery, the recovery efficiency is about 71%, which saves energy. Moreover, the system can filter and purify fresh air, and can also filter 51% of PM2.5. The fresh air quality is very high and the cost is high, so it is suitable for people who have high requirements on fresh air quality or large-sized villas.
One-way fresh air system can organize air intake and exhaust, with good air circulation effect and high ventilation quality. However, because the incoming air cannot be filtered and sterilized, the quality of fresh air is average and the cost is relatively low, so it is an economical and affordable mass product.
The ducted fresh air system is provided with air inlet and air outlet separately, which does not need additional indoor ducts. It is mainly used for local air supply of houses. If you don't want to install fresh air systems in the whole house, but only in local areas, such as guest restaurants or entertainment rooms, then ducted fresh air is the best choice.
while paying attention to the use requirements, the installation of fresh air system must also consider the actual situation of the house. Fresh air is a complete system. Besides the fresh air blower, it needs to be perforated, ducted, and designed for exhaust and intake. Therefore, when purchasing fresh air system, we must also consider the requirements of the house when installing fresh air. If the new house has not been decorated, and the height and structure allow, it is recommended to install a total heat exchange fresh air system, which has stable ventilation and little change in indoor temperature and humidity, and can be used with air conditioning to save costs for long-term operation; However, if the structure of the beam is complex, the height of the beam is limited, and it is inconvenient to drill holes, you can't install a new fan with total heat exchange, so you can only choose a unidirectional flow blower with few pipes and simple installation. And if the house has been renovated, only a split fresh air system can be installed.
How to choose the fresh air system? The choice of fresh air system cannot be "one size fits all". We must tailor the fresh air system for home use according to our actual situation. For the fresh air system, it is more important to choose a company with a strong after-sales service team. If you are still not clear about what kind of fresh air system you want to choose, you can consult Chinese HVAC, and the designer will design the most suitable fresh air scheme according to your specific use needs, room type and required fresh air volume.
