AI Overview
Scroll ground water heat recovery units are highly efficient, modular water-to-water heat pumps using scroll compressors to provide simultaneous space heating/cooling and domestic hot water by transferring heat between a building and a ground-water source. These systems, common in 10-85 ton capacities, feature independent refrigerant circuits for high-efficiency, sustainable, and low-operating-cost climate control.
Key Features and Benefits
- Modular Design: Allows scaling capacity by adding modules, suitable for commercial, industrial, or large residential projects.
- High Efficiency: Uses geothermal energy, achieving very high Coefficient of Performance (COP) levels, often reducing energy use.
- Heat Recovery Function: Captures waste heat from air conditioning to generate free hot water (sometimes up to with specific refrigerants).
- Independent Circuits: Each module often includes two independent refrigerant circuits to maximize reliability.
- Components: Utilizes robust scroll compressors, shell-and-tube evaporators, and sometimes electronic expansion valves.
Common Applications
- Water-to-Water/Ground-Loop: Designed for closed-loop ground source geothermal heating and cooling.
- Commercial Buildings: Suitable for hotels, hospitals, office buildings, and residential complexes requiring simultaneous heating and cooling.
- Industrial Processes: Used for process cooling in plastic extruders, laser generators, and electroplating.
Manufacturers such as Multistack, Trane, and Bosch offer specialized scroll units for these applications.
