Ducted AHU Heat Recovery Installations

This type of system is similar to the previous example except that the extract air and fresh air are put through a form of heat exchanger prior to being exhausted and discharged into the space. In winter the warm air being extracted from the space heats the heat exchanger, this in turn heats the cooler fresh air being supplied back into the space, in summer the same principle acts in reverse. This type of system will provide cost savings to the previous type as the amount of energy being used to pre heat or cool the incoming fresh air is reduced. The AHU’s can be manufactured to suit any application from domestic to commercial. Both Daikin and Mitsubishi provide an internal ducted heat recovery fan coil unit which can communicate with their respective heat pump systems installed providing a packaged economic highly efficient HVAC installation.
