What You Should Know About An HRV/ERV System Before Buying Your New AC

Know About An Hrv/Erv System Before Buying Your New Ac

Over the years, construction parameters have changed dramatically. The rising threat of global warming has made builders and architects emphasize energy efficiency. Making homes airtight is one of the most critical parts of their schemes.  However, in the process, they often end up making a home completely devoid of any natural ventilation. Although the heating and cooling cost reduces considerably due to this change in the constructional method, it leaves no space for the indoor air to escape giving rise to a humid condition which promotes the growth of pollutants. This is where, the two systems –the heat recovery ventilator (HRV) and energy recovery ventilator (ERV) – cut in.

Let’s find out more about these two units in details and how they can help in reducing the discomfort resulting from excess humidity.

The Heat Recovery Ventilators (HRV)

Even though the relevance of HRV systems is more for the winter months, their contribution during the hot summer months cannot be neglected. Even though Florida is not known for the chilling winter, people at times feel the need for heat pumps for a couple of months. The heat recovery ventilator is utilized to keep the home warm minimizing the cost. Even during the summer months, the HRV cools down the incoming air keeping the interior cooler than the external atmosphere. Just like any conventional ventilation system, the HRV also has two fans in use – one that drives out the air from within, and the other one that pulls fresh air from outside. This joint system helps in ventilating the home improving the indoor air quality.

The Energy Recovery Ventilators (ERV)

The Energy Recovery Ventilator (ERV) is a distinct ventilation system which holds a similarity with the HRV on heat transfer grounds. But along with heat transfer, ERV also regulates the humidity level of the incoming air. This proves to be an excellent choice for Florida homes as they have to deal with extremely high humidity level during warm summer months. The only difference between HRV and ERV is that the former deals with the transfer of sensible heat, while the latter is designed to remove both sensible and latent heat.

The ideal humidity level indoors is between 30 and 60 percent, but maintaining it throughout is not easy. HRV and ERV systems not only promote the circulation of fresh air inside your home, but also improve the indoor air quality, and help to reduce the household utility cost.
