by Shane Henson — November 30, 2011—Building owners seeking a way to lower energy consumption in their buildings and earn points toward Leadership in Energy and Environmental Design (LEED) certification in the process may consider investing in Mammoth’s new A-Vintage horizontal (1/2 to 6 tons) or vertical (1 to 6 tons) water source heat pumps.
According to Mammoth, manufacturer of custom air conditioning solutions for controlling the environment inside of buildings, with an energy efficiency ratio (EER) up to 21.0 and a coefficient of performance (COP) up to 5.6, A-Vintage units can help lower energy consumption, operating costs and the carbon footprint of an HVAC (heating, ventilation, and air conditioning) system over its life cycle. In addition, units can contribute to higher energy rebates and help earn the maximum eligible points for optimizing energy efficiency in pursuit of LEED certification.
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, according to the company. 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 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.
“While water source heat pump systems—especially geothermal systems—are among the most efficient means to heat and cool buildings, the industry-leading EER and COP of A-Vintage units provide the opportunity to push that envelope even further for the lowest possible energy consumption and carbon footprint in support of our customers’ green building objectives,” said Dennis Nelsen, product manager for Mammoth.
