Bryant Heating & Cooling Systems: Variable-Speed Heat Pump

Variable-Speed Heat PumpThe Evolution® Extreme variable-speed heat pump (280ANV) has efficiencies of up to 13 HSPF and up to 20.5 SEER. When combined with an Evolution control and Evolution gas furnace or fan coil, the heat pump utilizes a variable-speed compressor to precisely match its operation to the heating and cooling needs of the home. The control monitors the inside and outside conditions and adjusts the speed and capacity of the heat pump and indoor fan motor up or down to match the desired comfort settings. The variable-speed technology makes the unit a highly efficient heat pump. It also gives homeowners the comfort of consistent indoor temperatures while reducing energy use and lowering utility bills. The heat pump requires only two communication wires from an Evolution gas furnace or fan coil to the outdoor unit for full variable-speed functionality, and the control board provides enhanced diagnostics for faster service. Constantly monitoring pressures, temperatures, and electrical information critical to the system’s operation, the heat pump control board communicates with the Evolution control to adjust the heat pump’s operational settings as needed. Contractors can easily view detailed diagnostics and a wide range of system status information on the Evolution control screen, making service quick and easy. In addition, the new refrigerant charge assist mode helps installers ensure the system is charged correctly, based on specific configuration factors, including the indoor coil, line set diameter, and line set length.
