Heat Recovery Ventilation
A heat recovery ventilation system modulates the
temperature and humidity of incoming fresh air to match
A balance is therefore achieved between indoor
and outdoor ambients, enabling the cooling or
heating load placed on the air conditioning system
to be reduced significantly.
HRV units can be controlled individually or
integral with air conditioning system.
