Product Overview
The Volumetric Heat Exchange Unit is an intelligent heat exchange system integrating a heat exchanger, circulation pumps, make-up pumps, temperature control valves, electrical control cabinet, and various sensors. With modular design, the equipment is assembled and tested at the factory, requiring only pipeline and power connections on-site. It is widely used in central heating, air conditioning, and industrial process heat exchange applications.
Working Principle
The Volumetric Heat Exchange Unit exchanges heat between the primary heating medium (steam or high-temperature water) and secondary circulating water in the heat exchanger. The control system automatically adjusts the primary side electric control valve based on secondary water outlet temperature and outdoor temperature sensor signals, achieving precise control of secondary supply water temperature. The make-up system automatically activates the make-up pump based on system pressure to maintain stable pressure.
Technical Features
- Highly integrated, compact footprint, quick installation, short construction period
- Intelligent control, fully automatic operation, no dedicated operator required
- Climate compensation control, automatically adjusts supply temperature based on outdoor temperature, significant energy savings
- Variable frequency speed control, automatically adjusts pump speed based on load changes, reducing energy consumption
- Multiple protection functions: over-temperature, over-pressure, water shortage, power failure protection
- Remote monitoring, supports mobile APP and computer real-time data viewing
Applications
- Urban central heating exchange stations
- Large commercial complex air conditioning systems
- Industrial process cooling and heating
- Hot water supply systems for hospitals and schools
- Residential heat exchange stations
- Data center cooling systems
Selection Guide
When selecting the Volumetric Heat Exchange Unit, determine the heat exchanger specifications and pump flow based on heating area or heat load. Primary medium parameters (temperature, pressure) are key selection criteria. Variable frequency pumps are recommended to adapt to load changes, achieving 20%-40% energy savings. The control system should include outdoor temperature compensation for demand-based heating.
