The commercial grade QV Series, a Florida heat pump geothermal system, is an industry leader in sound reduction and represents one of the most comprehensive sound performance offerings on the market. In addition to the lower sound levels, the QV Series also delivers a compact cabinet, in a very competitive package, making it ideal to fit into small spaces in commercial buildings.
The QV Series includes a highly efficient, Constant Airflow ECM DEC Star Blower that produces the same cfm of airflow as the Bosch LV model, but at a lower rpm, resulting in decreased power consumption and sound. The QV heat pump also features Bosch’s patented compressor encapsulation, which includes high-density, mass-loaded vinyl insulation material wrapped around the blower and also installed in the lower compartment, dampening the sound it emits.
Additionally, encapsulation parts are installed around the compressor and assembled with heavy-gage sheet metal and a double layer of vinyl material on both sides. The access panels and the unit’s divider use the same type of sound attenuation material, making the panels substantially heavier, thus highly reducing the sound radiating from the unit. As a final measure, the compressor is installed on an isolated and elevated base plate that dampens vibrations during operating cycles.
The overall lowest sound rating for the commercial QV Series heat pumps is 53 dB, making it an industry benchmark, and an excellent solution for designers to improve NC ratings in commercial spaces; e.g., school classrooms and office spaces.
