Port Configuration and Airflow Model FC95HRV
In order to make the HRV as space efficient as possible, the
INDOORsupply and return ports are converted from round to oval
shape. Overall size of the port remains the same. Simply bend a
standard duct fitting to the correct shape, and attach to the ova l
portusing the same method as for a round port.
FC95HRVAir Flow
Staleair enters the FRONT-RIGHT side port. The air passes down
thefront half of the core, then up the back half of the core and out
theRIGHT-REAR port.
Freshoutdoor air enters the LEFT-REAR port and passes down
theback half of the core. Then the fresh outdoor air passes up the
fronthalf of the core and out the LEFT-FRONT port. This
configurationallows the air to actually travel through the core
twice,which makes the FC95HRV nearly as efficient as a double
coreunit.
