Residential ERV/HRV is whole house ventilation with heat recovery. You can also call it whole house air exchanger or whole house fresh air system.
Constant fresh air in your home is an important aspect to maintain the indoor air quality. A good ventilation system will protect your family from unpleasant odors and harmful contaminants such as formaldehyde and VOCs. Opening window is a simply way to increase ventilation, it can make your air feel less stuffy, but pollen and other allergens will be invited into your home at the same time.
Alston Ceeyee Invented a kind of whole house fresh air system, which can realize indoor air circulation. It can bring in fresh air from outside after sterilization, and filtration, meanwhile, the indoor air is discharged from the room. There is an air-to-air heat exchanger inside too, which realizes heat exchanging between the two air streams. It can be installed in most indoor environments, which is convenient to install and comfortable to use. The residential ERV/HRV is a healthy choice for home life.
Commercial ERV/HRV has bigger airflow type than residential ones, widely used in large commercial buildings and industrial applications, such as office buildings, hotel, theater, Hospitals, labs, confinement center, school, bank, etc.
It's also balanced ventilation system which use both an exhaust air blower and a supply fan that does not pressurize a building. Stale room air is exhausted and fresh outdoor air is brought into the structure. And there is air-to-air heat exchanger that is designed to transfer heat and sometimes moisture between two air streams. They improve the indoor air quality and reduce the load on air handling units to be more energy saving and efficient.
In these buildings, ventilation and fresh air are the key factor to consider when designing. Thanks to our commercial energy recovery ventilator, continuous fresh air will be introduced into the indoor area with lower cost.
Home ventilator is Uni-Flow wall mounted ventilator. It can only bring in fresh outside air, and filtered it even preheated it if necessary. Mainly to supply fresh air to the indoor area. The ventilator use at home also needs to dig a hole on the wall. When bringing in fresh air, the house will be under negative pressure. And stale air will be pushed out from the door and window gaps. Or we can also add exhaust fans in washing room or kitchen.
