HON MING Project｜Tianjin Metro Line 7-Dasi Depot

Project News

With the fast development of urban rail transit, energy-saving, environment friendly, efficient and stable HVAC systems have become an important consideration in the construction of subway depots. The Tianjin Dasi Depot Project-Metro Line 7 actively responds to the China "dual carbon" strategy and purchased 72 sets 170KW low temperature air cooled heat pump units of HON MING brand to provide efficient, energy-saving and reliable temperature control solutions for subway operations, further promoting the construction of green subways.

Tianjin Metro Line 7-Dasi Depot

The project is located in Saida avenue north, Saida 8th branch road east, Jingang Highway west, Lubei road south, Xiqing District, Dasi Town, Tianjin. The depot comprehensive base covers 350,000 square meters, which is the big project of comprehensive and functional on the entire line. As an important part of ensuring the smooth opening and operation of Tianjin Metro Line 7, this project has the characteristics of covering many disciplines, large area, large construction scale, strict technical standards, and strong professionalism.

HON MING Solution

Dasi Depot of Tianjin Metro Line 7 is important hub for parking, maintenance and dispatching of subway trains, it has strict requirements on the reliability, energy saving and environmental adaptability of HVAC equipment.

To ensure efficient and stable operation of the air-conditioning system, HON MING team designed the scientific and reasonable equipment selection and installation plan based on the actual needs of the project and the climate characteristics of Tianjin.

The project is located in Tianjin, a coastal city with high humidity and salt content in the air. It has a warm temperate semi-humid continental monsoon climate with a large temperature difference between winter and summer. Considering the project's characteristics as a vehicle depot maintenance depot and parking garage with large space, by selecting Hongming low-temperature air source module air-conditioning units, combined with scientific system design and environmental adaptability optimization, key technical problems such as low-temperature heating, large space heating, and corrosion prevention have been successfully overcome.

The Dasi Depot of Tianjin Metro Line 7 uses 72 sets 170 low-temperature air source heat pump units from Hongming, which not only improves the energy efficiency and environmental friendliness of subway operations, but also provides a demonstration case for the green and low-carbon development of rail transit across the country.In the future, as more subway projects pay more attention to energy-saving technologies, efficient and environmentally friendly solutions such as Hongming air conditioners will become the industry's preferred choice, helping China's rail transit move towards a more sustainable future.

HON MING low temperature air source heat pump unit

HON MING air-cooled module (cold/hot water) unit is an integrated central air-conditioning unit that uses air as the cold and heat source and water as the cold and heat supply medium. It is a high-efficiency and environmentally friendly air-conditioning unit launched by HON MING based on its many years of experience in designing and manufacturing air-cooled heat pumps.

The units are divided into cooling only type, heat pump type, year-round refrigeration type, low temperature type, etc., with the characteristics of flexible layout, beautiful appearance, saving building space, low operating noise, etc. Due to its equipment investment flexibility and simple engineering installation, it has always been the best choice for central air-conditioning systems and is widely used in commercial, industrial and civil buildings such as villas, hotels, hospitals, office buildings, entertainment venues, cinemas, etc.

HON MING air-cooled module (cold/hot water) unit has obtained the China Product Energy Saving Certification, far exceeding the national energy-saving standards. The unit uses the internationally recognized environmentally friendly refrigerant R410A. Compared with ordinary units, it has the characteristics of less refrigerant filling, higher energy efficiency, lower operating costs, and environmental friendliness.

Unit Features:

※High efficiency and energy saving--jet enthalpy increase technology. The EVI high-efficiency jet enthalpy increase compressor injects additional medium-pressure refrigerant, achieve double compression with one compressor;

※Ultra-low temperature operation.Normally, the highest hot water outlet temperature can reach 60℃. In a low temperature environment of -20℃, the highest hot water outlet temperature for heating can reach 50℃.

※Super compatibility, uninterrupted operation. The master and slave modules can be switched freely. When the master module fails, the operation of the entire system will not be affected. Each system of the equipment is designed and operated independently, which is convenient for installation and maintenance.

※Multiple modules can be freely matched and combined for flexible application.Adopting optimized module design, modules of different models can be freely combined to meet the load requirements of various buildings;

※ V-shaped heat exchanger, energy-saving and more efficient.The unit condenser adopts a new optimized V-shaped fin heat exchanger, which uses CFD simulation to simulate the wind field and optimize the V-shaped angle, which is more in line with the air flow characteristics, and the airflow organization is more uniform and the heat exchange is sufficient, and the efficiency is increased by 30%;

※ Microcomputer precise control.Adopt microcomputer control system, large-screen LCD text display, and friendly human-computer interaction page;

※Intelligent fast defrosting.The unit can independently determine the defrost conditions and realize intelligent and rapid defrosting to ensure long-term heating operation.
