Holtop Provided a Full-Scenario Air Handling Solution for Haidian Joy City Project
The Haidian Joy City project is a key project of the 100 major projects for improving people’s livelihood. It is also the fourth Joy City in Beijing. With an open design featuring “a mall box + blocks + a sunken plaza”, Haidian Joy City connects commercial areas, residential quarters and industrial zones via sky corridors, forming a “comprehensive ecological chain integrating commerce, industry, culture, tourism, technology and residence”. Holtop leveraging its leading energy-saving air handling technology, has customized an energy-efficient, environmentally friendly and comfortable air conditioning system solution and supporting products for the project, helping it become a new benchmark for regional green and smart commerce.

As an ultra-large commercial complex, Haidian Joy City imposes extremely strict requirements on its air conditioning system. The system must not only comply with Beijing’s energy conservation regulations and air conditioning operation standards for commercial premises, but also meet special requirements such as on-site installation. Meanwhile, the project has a tight construction schedule and high delivery standards. Thus, great challenges lie in implementing the system quickly while ensuring comfort and energy efficiency.

In response to these requirements, HOLTOP relying on its profound technical accumulation in the field of energy-efficient air handling, has customized a full-scenario HVAC (Heating, Ventilation, and Air Conditioning) solution by integrating the characteristics of different functional areas within the commercial complex. The project adopts a rotary heat recovery air handling unit, which balances the needs of energy conservation and consumption reduction as well as temperature and humidity control, thereby creating an efficient, stable, and comfortable indoor air environment for the mall’s public areas and various merchant spaces.

Highlights of the Air Handling Solution
In large-scale commercial complexes, the energy consumption of air conditioning systems accounts for a persistently high proportion. Therefore, ensuring the comfort of the shopping environment and air quality while achieving energy conservation and consumption reduction has become a core issue of great concern to project operators.
The Haidian Joy City project has adopted HOLTOP’s rotary heat recovery air handling units, which are equipped with core rotary heat recovery devices. These units efficiently recover energy from exhaust air, significantly reducing the overall energy consumption of the system and providing solid support for building a “green, low-carbon, and smart” commercial environment.
In terms of noise control, HOLTOP’s modular air handling units adopt a high-strength aluminum alloy frame and a “sandwich” panel structure, which provide excellent thermal insulation and sound insulation performance. Additionally, multiple noise reduction measures have been added inside the units to ensure stable, efficient, and low-noise operation, thereby creating a comfortable environmental experience for customers and merchants.
The unit adopts a multi-stage filtration solution combining plate-type filtration and electronic purification, which effectively blocks dust and particulate matter, ensuring that the air entering the indoor space is clean and fresh. This not only effectively guarantees the freshness and cleanliness of the air inside the mall, creating a comfortable and healthy shopping and leisure space for consumers, but also provides a sustainable development path for commercial operations.
Based on the characteristics of this project, HOLTOP’s technical team developed a specialized design plan, while its production team completed the supply and installation of 126 sets of equipment in advance, ensuring both quality and quantity.
Conclusion
The Joy City Project Department has an excellent team of operation experts and outstanding air conditioning system consultants, who exercise strict control over the equipment’s air velocity, energy efficiency, noise levels, as well as cooling and heating performance. Ultimately, HOLTOP successfully passed the acceptance inspection under these high requirements. consumers, but also provides a sustainable development path for commercial operations.
Since its official opening, Haidian Joy City has become a large-scale commercial complex with a comprehensive range of business formats in the region. In this project, Holtop provided a full-scenario air handling solution: its air conditioning equipment creates a comfortable environment for the entire complex, while the heat recovery technology significantly reduces energy consumption, achieving the dual value of “energy conservation + cost reduction”. This not only enhances the vitality of regional commerce and supports the economic development of northern Haidian, but also demonstrates HOLTOP’s leading strength in the air handling field for large-scale commercial complexes, setting a new model for green commercial buildings.
