House Ventilation System

How many kinds of mechanical ventilation for building? Which one is better?

There are four basic mechanical ventilation systems — exhaust, supply, balanced, and energy recovery.

Exhaust

Pors

1. Saving money and easy to install.
2. Work well in good weather.

Cons

1. Can absorb pollutants into living space.
2. Not appropriate for bad weather, such as raining, windy and humid climate.
3. Can increase heating and cooling costs.
4. Can cause air backflow in combustion appliances.

Supply

Pros

1. Relatively cost less and easy to install

2. Can remove the humidification of outdoor air

3. Work well in hot or mixed climates.

Cons

1. Absorb the pollen and dust in outdoor air.
2. Cann’t remove moisture from incoming air.
3. Can increase heating and cooling costs.
4. Not appropriate for bad weather, such as raining, windy and humid climate.

Balanced

Pros

Appropriate for all climates.

Cons

1.Can cost more to install and operate than exhaust or supply systems.

2.Cann’t balance the temperature and humidity from incoming air.

3.Can increase heating and cooling costs.

Energy Recovery & Heat Recovery Ventilators

Pros

1.Reduce heating and cooling costs.

2.Cheap installation cost for both small wall- or window-mounted models. 

3.Balance the temperature and humidity from incoming air.

4. Energy recovery ventilator can filter the incoming air

5.Cost-effective in climates with extreme winters or summers and high fuel costs.

Cons

1.Can cost more to install than other ventilation systems

2.May need to find experience installation person to install these systems

3.Require freeze and frost protection in cold climates
