High-efficiency horizontal and vertical water-source heat pumps in the A-Vintage line offer EER up to 21 and COP up to 5.6. The horizontal (½ to 6 tons) and vertical (1 to 6 tons) water-source heat pumps provide energy efficiency in geothermal and boiler/tower heating and cooling applications. The units can contribute to higher energy rebates and help earn the maximum eligible points for optimizing energy efficiency in pursuit of LEED certification, the company says. To achieve high-efficiency ratings and maintain peak efficiency throughout their operating range, A-Vintage units incorporate a three-speed PSC motor for sizes 006 to 012 and electronically commutated motor (ECM) for sizes 015 to 072, as well as a two-stage scroll compressor for sizes 024 to 072. Units are ETL listed and AHRI/ISO 13256-1 certified for capacity and efficiency. Several control options are available to meet different needs for system monitoring and management. The HP-5 controller provides easy, reliable, and stand-alone control. A standard DDC controller can easily be customized to meet any sequence of operation required in standalone mode or while connected to a building automation system (BAS) that uses industry-standard protocols (BACnet, Modbus, N2, and LonTalk). An optional EPiC™ controller combines a software approach that works over a wide range of control protocols with specific hardware interconnection tools.
