Envicool COOLTEK Rail Transit Air Conditioners Enhance Comfort on Zhengzhou Metro's 'Leisure Shopping Line.'

Recently, the first phase of Zhengzhou Metro Line 8, known as the "leisure shopping line", was officially opened. The air conditioning system of the trains on this line is provided by COOLTEK, a subsidiary of Envicool.


Zhengzhou Line 8 Phase I is currently the longest subway line in Zhengzhou and the fourth fully automatic subway line in Zhengzhou. The trains on this line are equipped with COOLTEK rail transit air conditioners to create a comfortable travel experience for passengers with precise and stable temperature control and efficient air purification technology.


In response to the needs of the long life cycle of the rail transit system, COOLTEK rail transit air conditioning products have undergone harsh environmental tests such as EMC and vibration to ensure the ultra-long system lifespan. At the same time, by applying special energy-saving solutions for rail transit air conditioners, COOLTEK rail transit air conditioners can achieve higher heat exchange efficiency, innovative air supply and return air mode, efficient air supply, and low-noise operation.


Envicool customizes professional rail transit air purification solutions that integrate air filtration, purification, quality inspection and other functions to cope with the characteristics of densely populated carriages. At the same time, by setting up multiple sensors and carrying the Envicool "Environmental Control Cloud" platform, the solution monitors the train environmental parameters and unit status in real time, can accurately adjust the carriage environment, and realize predictive maintenance of equipment.


To ensure the normal operation of the air-conditioning system and avoid affecting other equipment, the main components of COOLTEK air conditioners are equipped with overload, overheating, short circuit, overvoltage, undervoltage, phase loss, compressor high-pressure and low-voltage protection, as well as load reduction, software and hardware interlocking and other logical protection functions. A variety of operating modes can be selected according to the working conditions to ensure that the system always operates stably and reliably in a safe state. COOLTEK air conditioners focus on designing, developing and manufacturing safe, reliable and efficient rail transit train air conditioners. COOLTEK air conditioners have been successfully applied to many subway lines in Shanghai, Suzhou, Guangzhou, Zhengzhou, Wuxi, Shenzhen and other places, and provide customers with worry-free services throughout the life cycle by building a complete large-scale rail transit air conditioning maintenance platform. COOLTEK air conditioners will continue to provide customers with high-quality products and solutions, assist rail transit construction, and promote the accelerated development of urban smart transportation.
