Product Features
100% Fresh Air Processing Unit

A single system can effectively combine both fresh air filtration and heating/cooling functions. By connecting indoor units and the Fresh Air Processing Unit to the same refrigerant system, it offers enhanced design flexibility and significantly lowers the overall costs of the system. This integration allows for efficient management of air quality, temperature control, and ventilation in a comprehensive manner.

Discharge Air Temperature Control

Unlike conventional indoor units that utilize return air temperature control, the fresh air processing unit takes a different approach by employing discharge air temperature control. This unique method helps in reducing the air conditioning load. By regulating the temperature of the discharged air, the fresh air processing unit optimizes the cooling or heating process, resulting in a more efficient system. This approach helps to minimize energy consumption and enhance overall system performance, leading to lower operating costs.

Digital Display On/Of

During nighttime, the displays of indoor units can be turned off, providing a more conducive environment for rest. This feature allows individuals to enjoy a dark and peaceful sleeping environment without any distractions caused by the illuminated displays. By deactivating the displays, the indoor unit promotes better sleep quality and helps individuals to relax and unwind during the night. This feature is especially beneficial for light-sensitive individuals or those who prefer a completely dark room for a more restful sleep experience.

Buzzer Sound On/Of

To ensure a quieter environment, the indoor unit can be configured to disable the buzzer sound, preventing any disturbances to the user. This feature allows individuals to enjoy a peaceful atmosphere without any unnecessary noise interruptions caused by the indoor unit. By turning off the buzzer sound, the system operates silently, promoting a calm and serene ambiance within the space. This is particularly beneficial for environments where noise reduction is desired, such as bedrooms, offices, or areas where concentration and relaxation are important.

Optional G3-class Air Filter

The installation of a G3-class filter in the Fresh Air Processing Unit is an optional feature. This particular filter has a filtering effect that can reach up to 80%-90% when it comes to capturing coarse dust particles with a size greater than 10 µm. By incorporating the G3-class filter, the Fresh Air Processing Unit significantly improves the air quality within the living environment. This filter effectively traps and removes larger particles, resulting in a cleaner and healthier indoor atmosphere. By reducing the presence of coarse dust, the G3-class filter contributes to creating a more pristine living environment.

Static Pressure 20 Steps Control

In order to adapt to different installation environments, the Medium Static Pressure Duct system allows for precise control of static pressure. This control is achieved through a wired remote controller, which offers up to 20 steps of adjustment. By regulating the static pressure, the system ensures a comfortable environment that is well-suited for various settings. Whether it’s a large space or a smaller area, the Medium Static Pressure Duct system can be fine-tuned to deliver optimal comfort. This level of control enables users to create the desired airflow and temperature distribution, resulting in a pleasant and accommodating indoor environment regardless of the specific installation conditions.

Wide Operation Range

The Fresh Air Processing Unit offers a high level of flexibility in terms of installation locations. It can be conveniently installed in virtually any suitable area. Furthermore, this unit is designed to operate effectively across a wide range of outdoor ambient temperatures. In cooling mode, it can withstand outdoor temperatures of up to 50°C, ensuring efficient cooling performance even in hot climates. On the other hand, in heating mode, the unit can operate in temperatures as low as -10°C, allowing for reliable heating capabilities even in colder environments. This versatility in temperature tolerance enables the Fresh Air Processing Unit to provide optimal performance and maintain a comfortable indoor environment regardless of the prevailing outdoor conditions.

Flexible Duct Design

The Fresh Air Processing Unit is designed to provide a wide range of static pressure, ranging from 30Pa to 400Pa. This broad static pressure capability makes it suitable for supporting various duct configurations, from short to long ducts. Additionally, it is well-equipped to accommodate high-ceiling air supply setups. With its ability to handle different static pressures, the Fresh Air Processing Unit ensures efficient and effective air distribution throughout the entire duct system, regardless of the length or height of the ductwork. This flexibility in static pressure support allows for versatile installation options and optimal air supply to meet the requirements of different environments, including spaces with high ceilings.

High External Static Pressure

The Fresh Air Processing Unit offers a high external static pressure capacity, allowing for more flexible duct applications. For models 125 to 140, it can handle up to 196Pa of external static pressure, while models 200 to 280 can handle up to 280Pa. This increased static pressure capability provides greater flexibility in designing and configuring the ductwork.

When it comes to air supply, the Fresh Air Processing Unit can effectively distribute conditioned air up to approximately 14 meters in length. Additionally, it is capable of providing air supply to spaces with a ceiling height of approximately 6.5 meters. These specifications ensure that the unit can efficiently deliver conditioned air to a variety of spaces, accommodating different duct lengths and ceiling heights.

Overall, the Fresh Air Processing Unit’s capabilities in handling static pressure, air supply length, and ceiling height contribute to its versatility and adaptability in various duct applications.
