Copeland's District Heating Variable Speed Solution Empowers College to Create a Comfortable and Green Campus

Suzhou, China (March. 12, 2025) — Copeland, a global leader in sustainable climate solutions, partnered with EUROKLIMAT to deliver an ultra-low temperature variable speed heat pump system for Zaozhuang Vocational College that was completed in 2024. This innovative project provides robust performance in low temperatures, flexible operation and energy savings, standing as a model for sustainable heating technology designed for colder climates in the northern region of China. It exemplifies Copeland's dedication to assist customers in resolving energy efficiency challenges and fostering the growth of China's environmental and energy conservation sectors through cutting-edge technology and sustainable practices.

As China deepens its national dual-carbon strategy and key policy documents are introduced, the importance of strict energy standards and clean heating for buildings in Northern China is clear. Copeland is committed to elevating heat pump technology and broadening its applications, aiding the industry's shift towards a low-carbon, eco-friendly, and energy-efficient future.

The newly built Zaozhuang Vocational College was completed in 2024. The project targeted maximization of energy efficiency under partial load conditions, while providing cooling in summer and heating in winter.  In addition, the low-temperature and high-humidity environment, varying water temperature requirements for conventional heating, distributed installation, and noise reduction demands all posed application challenges which were effectively overcome.

147 EK ultra-low temperature variable speed air-cooled heat pump units equipped with Copeland DC variable speed scroll compressors.

Copeland's 25HP ultra-low temperature variable speed scroll compressors provided the college with multiple benefits:  

• High efficiency 
  Copeland’s solution is equipped with unique technologies, such as variable compression ratio and Copeland’s exclusive “SWING LINK” scroll centrifugal force balancing, meeting the new energy efficiency standard for both cooling and heating. Compared to traditional heating methods, the heat pumps have demonstrated over 30% energy savings*.

• Precise temperature control
  DC inverter technology enables precise and flexible stepless adjustment, resulting in more accurate water temperature control, faster response, and reduced noise and grid impact.

• Economic advantages
  Enhanced Vapor Injection (EVI) technology broadens the units' operating range. Copeland's variable speed compressors achieve over 5.0 energy efficiency under partial load, saving costs for the college.
