Fresh Air System ERV & HRV

Air system,ERV and HRV,ERV,HRV


First of all, HRV and ERV are both air exchanger systems installed in the house to help air circulation and keep indoor air fresh without opening windows. It is more necessary to establish a new air system in newly built homes, recently renovated houses, and houses with a strong pet smell.

Will there be any problems if there is no fresh air system? There will be no fatal effect. After all, this kind of equipment will increase the comfort of your living. However, if there is no fresh air system, the windows will not be opened in winter, and the indoor carbon dioxide concentration will be too high, resulting in poor breathing and dizziness for a long time.

The fresh air system will also help save Energy and heating costs, automatically adjust the indoor temperature in winter and summer, and effectively prevent mold and bacteria in the house.

The main difference between Heat Recovery Ventilation (HRV) and Energy (or Enthalpy) Recovery Ventilation (ERV) is in humidity. They are just like the lungs of a house, and ERV not only exchanges air but also regulates indoor humidity while HRV exchanges air. So the cost of ERV is higher than HRV. Of course, if you have a whole-house humidifier installed at home, there is no need for an ERV.
