In February, Fraser Engineering Company, Inc. completed a HVAC retrofit at the Moakley Courthouse. The Moakley Courthouse is known as a unique American landmark, "where the charisma of Boston meets the open sea."  It is now also known as the first U.S. General Services Administration building to have the new City Multi VRF (Variable Refrigerant Flow) System installed.

The Courthouse, known for its architecture, needed renovations to its HVAC system as part of a plan to increase the system's operating efficiency. Fraser Engineering was selected to install Mitsubishi's VRF System, a system which is new to the USA and requires specialized factory training to install and service. This new zoning system allows one zone of the building to be heated while another zone cools. A single network is able to manage all zones to meet the needs of the individuals within the building. The benefit of this type of system is that you have both maximum comfort for the occupants while saving money by cooling and heating each zone simultaneously. VRF systems constantly modulate the amount of refrigerant being sent to each evaporator. By operating at varying speeds, VRF units work only at the needed rate, which is how they consume less energy than on/off systems.  Click here to learn more about Mitsubishi's VRF System.

 In addition to the challenge of working with new technology, Fraser's team had to work in a very secure environment with the majority of the work completed at night so as not to disrupt the daily operations of the Federal Courthouse. We are very excited about what the VRF Systems mean for our industry. The future of HVAC has arrived and Fraser Engineering Company, Inc. was there to install it.
