FOREIGN LANGUAGE SCHOOL, Jiahui, China

Jiahui Oak Foreign Language School is a prestigious private educational institution located in Dalian, one of the leading educational centers in Liaoning Province (China). Founded in 2015, the school covers an area of approximately 80,000 m² and accommodates over 830 students and 150 teachers. It offers a full cycle of education from kindergarten through high school and prepares students for international exams, including IGCSE and A-levels, which are taken in English.

Establishing Premium Educational Standards

This educational institution was established to shape future leaders who think globally and have a responsible attitude toward learning. The school particularly emphasizes its elite status, the quality of the educational process, and the importance of a comfortable environment for students. That is why high standards are applied to all aspects of the infrastructure, especially when implementing ventilation systems for schools.

The project specifications set strict requirements for the ventilation for schools. The educational facility had to be supplied with fresh, clean, and safe air to ensure the well-being of students and teachers during long stays. This meant that the equipment had to not only maintain high-quality air circulation in the room, but also operate silently so as not to disturb the educational process. After all, it is especially important for the students of this school to be in a calm and comfortable environment that promotes concentration on learning, making proper ventilation in schools a critical factor.

Advanced HVAC Solution Implementation

The solution was to install a Blauberg KOMFORT EC DBE heat recovery ventilation unit. With an air flow of up to 2,100 m³/h, it ensures reliable air circulation even in large auditoriums attended by many students. The central element of the system is a plate heat recovery core, which achieves a heat recovery efficiency of up to 88%. This sophisticated approach to heating ventilation and air conditioning schools ensures optimal climate control throughout the facility.

Special attention has been paid to the casing design. Made of aluminum profile and insulated with a 20 mm layer of mineral wool, it provides heat and sound insulation. The fans themselves are known for their reliable and quiet operation. To keep the air clean, built-in G4 filters are used, which remove dust and impurities from the air, functioning effectively as an air purifier for classroom environments.The units are equipped with built-in S21 automation system, which enables their integration into a Smart Home or BMS (Building Management System). The units can be controlled remotely via the Blauberg AHU mobile app using Wi-Fi.

To conclude, it should be noted that the unit is easy to maintain: thanks to the hinged side panels, school technical staff can easily access the filters and internal components for timely cleaning and replacement, ensuring long-term and uninterrupted operation of the equipment.

Results and Benefits

By installing Blauberg KOMFORT EC DBE ventilation units, Jiahui Oak school now has a steady supply of fresh air with a controlled indoor climate in all classrooms. Heat recovery ensures a comfortable temperature without draughts or fluctuations, which is particularly important for learning. The air enters the classrooms preheated or cooled depending on the season, creating favorable conditions with no additional load on the heating or air conditioning systems.

The high energy efficiency of the equipment has enabled the administration to significantly reduce heating costs in winter and cooling costs in summer. And the system's silent operation does not distract students and teachers during classes.

Thus, Blauberg provided the school with efficient, reliable, and quiet ventilation that fully meets its needs and high requirements.
