Copeland has partnered with a customer to upgrade the HVAC systems of metro lines in a major city in central China. The deployment involves over 3,200 units of Copeland’s ZRH(V) series compact horizontal scroll compressors, aimed at enhancing energy efficiency and passenger comfort in public transportation.
The selected compressors are designed for compactness—under 200 mm in height—and can operate in ambient temperatures from -20°C to 45°C. These units are also compatible with low-global warming potential (GWP) refrigerants, supporting China’s sustainability and energy transition goals.
The HVAC systems face challenges due to varying underground and above-ground operations, extreme weather conditions, and high passenger volumes. Copeland’s compressors are engineered to perform reliably under these conditions, with features such as advanced oil circulation to reduce maintenance needs and ensure stable operation in high-vibration environments.
According to the customer, the third-generation ZRH(V) series compressors provide a balance of efficiency, reliability and compact design suited for rail transit HVAC applications. Reported benefits include stable cooling performance at temperatures up to 48°C, uninterrupted operation at up to 55°C*, noise reduction, and improved temperature control.
“Copeland is proud to support the modernization of China’s public transportation systems with advanced HVAC solutions,” said Galen Yin, vice president of China for Copeland. “By leveraging our global expertise and local partnerships, we are helping to create a more sustainable, energy-efficient future tailored to the unique needs of the China market.”
