INTRODUCTION

HRV - Aluminum Core

A Heat Recovery Ventilator (HRV) is designed to
provide fresh air into a building while exhausting
an equal amount of stale air. During the winter
months, the incoming cold fresh air is warmed by
utilizing the heat recovered from the stale air
before it is exhausted to the outdoors. During
summer months when the indoor space is air
conditioned, the Heat Recovery Ventilator will
help in cooling the incoming fresh air with the
stale air that is being exhausted.

ERV - Enthalpic Paper Core

An Energy Recovery Ventilator (ERV) is designed
to provide fresh air into a building while
exhausting an equal amount of stale air. An ERV
is designed for use in warm humid areas with
heavy air conditioning use. The ERV will transfer
both sensible and latent heat from the incoming
fresh air to the outgoing stale air thereby reducing
the load (due to ventilation) on the air
conditioning system.

ERVs are not suitable for climates where the
temperature drops below -4˚C (25˚F).
