Table 28. Application Map Descriptions
ZONE 1
True North - Cold Winter and Dry Summer
HRV
HRV is best for a very cold and prolonged winter.
ZONE 2
US - Canada Border - Cold Winter and Hot
Humid Summer - HRV or ERV
HRV is best for a cold or prolonged winter.
ERV will help reduce the AC load in the summer by transferring moisture.
ZONE 3
Central US - Moderate Climate - HRV or ERV
HRV and ERV will work equally well.
ERV will help reduce the AC load in the summer by transferring moisture.
ZONE 4
Marine Climate - HRV or ERV
Humidity and temperature are moderated by HRV or ERV.
ZONE 5
Arid Climate - Hot and Dry - HRV
HRV will transfer energy summer and winter. With little moisture to transfer an ERV
is not needed.
ZONE 6
Gulf Region - Hot and Humid Climate - ERV
ERV is recommended. Primary benefit is transferring energy and moisture through
-
out summer and winter.
NOTE: All HRV and ERV models have an integrated defrost system for cold climates..
ERV is recommended in regions where high outdoor humidity causes air conditioning operation for dehumidification more frequently than heating system operation.
