Title: Brukermanual for Refra varmepumpe.pdf
The key advantages of water-to-water heat pumps are as follows: • They can be use in all types of geothermal sources (open and closed systems) • They allow for significantly reduced distribution energy relative to forced air systems • They allow easy (hydronic-based) zoning, at lower cost than forced air zoning • They eliminate the need to route large central ducting in buildings • Can be used in combination with thermal storage • Can be used with thermal storage and off peak electrical rates • Can be used with thermal storage and solar thermal input • Can provide dedicated or ancillary domestic water heating • Can be used for producing “process water” in industrial applications • Multiple w/w heat pumps can be controlled as a staged system to better match loads • Multiple w/w heat pumps can be stacked to save space in mechanical rooms • Allow a hydronics professional to install system without refrigerant handling • Can be used for loads such as pool heating, spa or hot tub heating • Can be used in
