Anyone who has spent money on tightening up an existing home or spent extra for energy upgrades to a new home is irritated by the concept of ventilation mechanics. It is understandable that it is pointless to make a home more airtight then add a way for more outdoor air to enter, but their properly ventilated home is crucial. Why?

Indoor Air Quality-Indoor Air Quality or IAQ has become a buzzword in the HVAC industry. Sometimes buzzwords come about from the marketing or information, but here is a legitimate need, as homes are to restrict the pollutants are trapped at home. Older homes are naturally ventilated, but at the expense of comfort and efficiency. Indoor air begins and outdoor air and becomes the "dirtiest" of pollutants in the home, remove the dirty air ventilation and air dilutes the existing.

Common sources.

The excess moisture. High humidity can lead to condensation that can lead to mold.
Chemicals. paint thinners, cleaning products, insecticides such.

Building Products. Most of the newer products contain chemicals in their production lines or formaldehyde.

Pets. Dirt and dust and dander

Smoke. Candles smoking or even left out of the frying pollutants that make breathing difficult.

Energy Saving "The problem is the air that comes in whether you like it or not, any house of a certain amount of exhaust air through bathroom fans, kitchen range hoods, water heaters, ovens or furnaces old pipe, chimney effect leaky tin lights, HVAC boots, attic or clothes dryers. All the air coming out is replaced by cracks, outlet boxes, open doors, or much worse a counter-burning water heater. Because air is coming in our goal should be to control. Mechanical ventilation allows us to introduce into the duct system in which will be conditioned and filtered before entering the living room. Some types of equipment exchangers heat have to pull the heat from the air before it is exhausted.

Comfort. By controlling where the air coming in reducing the current and cold spots.

Security. We know that our homes air ventilation or exhaust air needs to be replaced, this is called negative pressure. The security problem occurs when a household has a fireplace or b-vent water heater starts again the wording of the negative pressure. If air is introduced through the b-vent heater fire water exhaust gases drawn from the draft diverter allows co2 in the house. mechanical ventilation reduces this condition. No matter the situation must have CO2 detectors in your home.

Basic types of ventilation

Exhaust ventilation-Removes the contaminant at its source, like a bath fan or kitchen range hood. While this qualifies as mechanical ventilation is not very optimal. Exhaust only leads to pressures unbalanced and potentially dangerous crosscurrents drafts.

Supply Ventilation-Provides a means of introducing fresh air into the home to replace the extracted air and help with the dilution of the pollutants of origin. Traditionally a duct is ran from the cold air return of your HVAC system measured outside by a barometric damper or an electronic damper opens and closes based on preset conditions. Of the two I prefer the electronic version. In carrying air through the return we can condition and filter the air before it enters the living room. Along with quality bathroom and kitchen exhaust fans this configuration is effective and should be your minimum standard.

Stands HRV/ERV- fan heat recovery and energy recovery ventilator. An HRV / ERV is a system balanced running exhaust air intake and exhaust through a heat exchanger, removing heat from our air conditioning before you can post elsewhere. An ERV is the same configuration also takes a shot of moisture great fit for warm humid areas. HRV can be installed independently or linked to the system ducts. On the basis of conditions set by the installer of the exhaust unit and replace the same volume of air with reduced heating load or cooling because of the heat exchanger. Another fantastic idea I saw at a distance implies a bathroom fan that pulls air from several bathrooms that ties into the ERV. Instead of sending the warm moist air out of it ran through the ERV.

Below is a generic diagram of a typical ERV.
