Air conditioners and fresh air systems are actually two different concepts with fundamentally distinct applications, yet many designers still confuse the two.
Today, we'll delve systematically into the new knowledge of ventilation that designers should be aware of. Along the way, we can compare the differences between air conditioning and ventilation.
What's the "new air" all about?
Why Are Everyone Using新风?
3) What's the difference between air conditioning, fresh air, and ventilation?
What are the categories of air purification systems? How do you differentiate them?
The Definition and Role of Fresh Air
What is新风?
In simple terms, everyone needs fresh air to maintain a normal lifestyle, and a ventilation system is the "mover of nature."
Utilizing professional equipment to bring the fresh air of nature indoors, even without opening windows, allows occupants to enjoy the embrace of the natural world. This ensures that indoor spaces maintain a healthy, natural, and comfortable environment.
What is the function of the new breeze?
△The primary function of新风
Our新风 systems primarily aim to ensure the air quality within indoor spaces, bringing in fresh air. Of course, you might ask, can't opening a window achieve the same effect of introducing fresh air?
Absolutely, it can be done that way, but what do you do when there are no windows, the windows can't be opened, or there's a lot of dust outside, or it's winter?
Therefore, the new ventilation system also boasts benefits such as dust removal, air purification, and noise reduction from opening windows.
What to do when outdoor air quality is poor?
△The Extraordinary Role of Air Purification Systems
In response to poor outdoor air quality, the strategy for our fresh air system is to add fresh air purifiers (air filters) at the intake pipe points. This purifies the polluted air before distributing it to various spaces, ensuring the air quality within the spaces and completely saying goodbye to the "pain of breathing."
For ease of recall, we can obtain an inappropriate
Analogous Conclusion: New air is the clear and elegant, clean "wind" of the air realm.
The Difference Between Ventilation Systems and Air Conditioning Systems
1. Conceptual differentiation
The definition of an air conditioning system encompasses: Broadly speaking, an air conditioning system is a general term for all air regulation systems, including the adjustment of temperature, humidity, cleanliness, air velocity, air pressure, noise, and air composition.
Air conditioning, in its narrow sense, is a system that regulates indoor air temperature through air conditioning equipment, while the fresh air system primarily takes on the role of improving air quality.
In simple terms: What we typically refer to as indoor air conditioning systems are devices that circulate the air within a room, allowing the air to play by itself, solely responsible for the temperature, but not the air quality.
The new air system introduces fresh air into the indoor space, allowing the indoor air to mix with the outdoor air.
Play together, be responsible for indoor air quality, but do not guarantee air temperature. Temperature regulation is only possible with an air-to-air heat exchanger installed in the air purifier room.
2. Ventilation Differences
Ventilation System Definition
Ventilation technology is used to control the indoor air environment, ensuring it meets the current national health standards. Essentially, this involves introducing fresh outdoor air, commonly referred to as "新风," or purified clean air into the building, or expelling polluted indoor air to the outside, under conditions that meet emission standards.
b. Ventilation Type
The ventilation system is divided into two main categories: supply air and exhaust air systems. The supply air system, commonly referred to, includes the fresh air system.
In China, when people usually refer to ventilation, it is generally the exhaust system we're talking about. Below, we'll compare and analyze the exhaust system and the fresh air system:
① Our work approaches vary.
Ductwork systems are
Our indoor air is connected to the outdoor air to achieve air convection. Only the bad indoor air is expelled, without introducing outdoor air.
The air purification system is typically used in conjunction with the exhaust system, meaning it not only expels polluted indoor air but also brings in fresh outdoor air, achieving a full exchange of indoor and outdoor air.
② Achieved different effects
Ducting systems are typically set up separately, such as common exhaust fans and ventilation openings. They use internal fans to expel indoor air, effectively removing moisture and odors.
The air purification system is often used in conjunction with central air conditioning, effectively enhancing the energy efficiency of the central air conditioning. For instance, in enclosed spaces, even with the air conditioning on, the per capita oxygen content may be insufficient, posing a risk of asphyxiation. Therefore, the air purification system exists to add sufficient oxygen to indoor spaces, ensuring fresh air.
③ Ventilation System Applications
The purpose of the exhaust system is to expel polluted indoor air to the outdoors. Therefore, it is essential to install an exhaust system in areas where there is heavy pollution and insufficient natural ventilation, such as restrooms, shower rooms, kitchens, small workshops, factories, experimental zones, and more.
In brief:
The ventilation system includes both supply air and exhaust air, with supply air encompassing fresh air, while exhaust air is often set up separately.
b. Fresh air systems are often used in conjunction with exhaust ventilation and air conditioning systems. You can consider the fresh air system as a comprehensive system for improving indoor air quality, while the exhaust system is only effective in removing impure air and humidity from indoors.
New ventilation system mode
Generally speaking, new ventilation systems are categorized...
For two modes: Pipeline and Non-pipeline types.
No ductwork required; achieve fresh air without the need for new ventilation ducts.
It utilizes independent fresh air equipment as the fresh air intake, exchanging indoor and outdoor air through the air intake.
Due to the fact that independent devices are part of a system on their own, they do not require ductwork for air supply and can be directly mounted on walls. The main unit operates to introduce fresh air into the room.
b. Since there is no involvement of pipeline equipment, the ventilation is solely carried out by the main unit, thus requiring individual installation and separate control for each room. Currently, it is only used for small spaces in the renovation of existing buildings.
In simple terms, the non-pipe type of air supply involves placing a machine directly indoors and using it to distribute air, without the need for ductwork. Its advantages are simplicity and directness, but its drawback is that it is only suitable for renovation of old buildings or small residential spaces.
2. There are various duct types
△ There is a new ventilation type with wind pipes.
There are duct types: supply air ducts required to introduce fresh air, achieving indoor fresh air effects.
This type of fresh air system shares the same installation principle as central air conditioning. It uses ducts to house the purification and air treatment of fresh air in a fixed area, then distributes it to various spaces through the ductwork, achieving centralized control.
