As the first commercial project launched and implemented in Lingang New Area, the supporting commercial project of Shanghai Lingang Tianchen has successfully passed the evaluation and acceptance for ultra-low energy buildings in Shanghai, ranking among the city’s first batch of public buildings certified for ultra-low energy performance.
Leveraging rich experience in air conditioning solutions for ultra-low energy buildings, outstanding heat recovery technology, and low-carbon energy-saving HVAC products, Holtop helps Lingang Tianchen create a healthy, comfortable and energy-efficient public space.
The supporting commercial complex of Lingang Tianchen integrates a fantasy commercial block, a literary & romantic themed block, a sports center, a sunken plaza connected to rail transit, an immersive theater and a hotel.
Through integrated technologies such as improving the thermal performance of building envelopes, optimizing electromechanical systems, and fully utilizing renewable energy, Lingang Tianchen aims to build a demonstration project for ultra-low energy public buildings.
Holtop delivers far more than just air conditioning equipment; it provides a core system solution to resolve conflicts among indoor air quality, energy consumption and compliance requirements for large commercial buildings.
In compliance with the project’s ultra-low energy building standards, Holtop customized a modular combination of outdoor units for direct expansion air handling units, rotary heat recovery air conditioning units, and Owind series fresh air ventilators.Low-carbon and energy-saving products that meet ultra-low energy building standards are adopted throughout the whole system from main units to terminal units. The reliable performance has been fully verified in subsequent operation, laying a solid foundation for the project’s official acceptance.
Improving indoor air quality and comfort is usually accompanied by increased energy consumption. As an ultra-low energy project, Lingang Tianchen sets stringent requirements on the heat recovery efficiency of HVAC terminal systems.
The project adopts Holtop rotary air handling units. The core component — rotary heat exchanger — is equipped with advanced molecular sieve coating to ensure high-efficiency heat exchange.
Meanwhile, it is compatible with smaller-sized cold and heat source units, which not only reduces equipment investment and floor space occupation, but also offers crucial support for the project’s full-lifecycle low-carbon operation.
The air conditioning main units adopt Holtop full DC inverter direct expansion air handling units.
Equipped with dual core configurations — DC inverter compressors and DC inverter fan motors, the units can rapidly adjust loading capacity in real time according to the load demand of indoor units, achieving precise operation control.
With stepless capacity regulation, the units accurately match load fluctuations and greatly reduce temperature variation.
Moreover, its Coefficient of Performance (COP) and Annual Performance Factor (APF) both exceed the requirements for main air conditioning units of ultra-low energy buildings, guaranteeing data collection for subsequent acceptance and operation.
Public buildings feature dense crowds and frequent human activities, imposing strict requirements on air freshness, cleanliness and comfort.
Holtop’s HVAC terminal system adopts a two-stage filtration scheme to ensure the supplied air remains clean, comfortable and odor-free at all times.
The intelligent control system continuously optimizes operating status and upgrades control strategies, automatically switching operation modes according to external environment and indoor passenger flow.It runs in high-efficiency energy-saving mode under normal working conditions, and activates forced ventilation mode automatically during severe air pollution or peak passenger flow, keeping the indoor environment always at the most comfortable level for occupants.
For ultra-low energy buildings, compliance with design standards must be verified through actual operation.With abundant domestic project references and extensive practical experience, all Holtop completed projects have passed strict energy-saving acceptance — a key reason why the project owner selected Holtop.
In the subsequent acceptance phase, all performance indicators met design expectations, enabling the supporting commercial project of Shanghai Lingang Tianchen to successfully obtain ultra-low energy building certification.It sets a replicable benchmark for high-density multi-functional public buildings to achieve ultra-low energy consumption, earning high recognition from clients for Holtop’s products and service capabilities.
Holtop is more than a supplier of HVAC products. It participates in projects in-depth from the initial scheme design stage, fully aligning with the overall energy-saving goals of the building.
We provide customers with complete HVAC system solutions, reduce the burden on building energy systems by adopting high-efficiency heat recovery technologies & products and optimizing cold & heat source configuration, and contribute to the sustainable development of green buildings with professional expertise and premium services.
