What is a fresh air system?

How does the fresh air system work? 1?3?1?3 With the advancement of science and technology, various new things are constantly emerging. When purchasing indoor ventilation equipment, many people find that in addition to traditional ventilation fans, exhaust fans and some fresh air functions, ventilation A new product, the fresh air system, has appeared in ventilation equipment. Many people are unfamiliar with the fresh air system. They don’t know what a fresh air system is, nor its classification and principles. The experts in this article will introduce these issues in detail below. Overview of the fresh air system The fresh air system is an air conditioning equipment that provides fresh air. It mainly consists of air inlets, motors, fans, filters, humidifiers, air valves, air outlets and other components. Its main function is to send outdoor fresh air indoors through a fan, replacing the original dirty air in the room when it enters the indoor space, thereby keeping the indoor air fresh and clean. The fresh air system is divided into three types: one-way flow, two-way flow and full heat exchange unit. The principles of the first two fresh air systems are simpler, while the full heat exchange fresh air system has an energy-saving heat exchange system, the working principle is more complex, and the use effect is also the best. OK Three major types of fresh air systems 1. One-way flow fresh air system One-way flow fresh air system is a "forced exhaust, natural air intake" system. Its working principle is to rely on the suction generated by the host machine to form indoor negative pressure and pass the dirty air through. The air supply duct is sent to the outdoors. In order to balance the negative pressure in the room, relatively fresh air from outside the room enters the room through the pre-installed air inlet to achieve the purpose of ventilation. The one-way fresh air system has natural air intake. The system has fewer pipes and is simple to install. It is generally used in residences, apartments or offices with higher building heights. 2. Two-way flow fresh air system The two-way flow fresh air system is a "forced exhaust, forced air supply" system, which consists of a set of forced air supply systems and a set of forced air exhaust systems. The difference from one-way flow is that the air supply form is changed from natural air to forced air supply. Fresh air enters the room through the ducts of the air supply system, and the exhaust air is discharged to the outdoors through the ducts of the exhaust system. The flow direction of the fresh air and exhaust air, the fresh air outlet And the layout of the air outlet can be actually arranged according to specific requirements. The two-way flow fresh air system can filter the introduced fresh air. The fresh air quality is good and the ventilation effect is more thorough. It can be installed and used in homes and public places. 3. Full heat exchange fresh air system The full heat exchange fresh air system is an upgrade of the two-way flow fresh air system. A full heat recovery system is added to the main unit. The air entering and exiting passes through the heat exchanger placed in the main unit and is preheated and pre-cooled. The energy exchange can retain 70% of the energy of indoor air. It is very energy-saving when used in conjunction with air conditioners. Even if the temperature difference is large, it will not affect the indoor temperature. The full heat exchange fresh air system is suitable for apartments, villas and offices with an area of ??less than 1,000 square meters. The fresh air is of high quality, efficient and energy-saving. In many of our company's villa customers' central fresh air system installation projects, full heat exchange fresh air is used. System series. What is a fresh air system? Simply speaking, a fresh air unit is a system that ventilates indoors and improves indoor air quality. It can reasonably and effectively discharge indoor polluted air and introduce fresh outdoor air. The three types of fresh air systems introduced above are different, and the applicable building types are also different. There are many fresh air unit products of these three types on this website. You can learn about the price range and user models of these products online.
