How Energy and Heat Recovery Ventilators Work
Also known as HRV systems and ERV systems, these ventilation devices operate using counter-flow current exchange. This means they draw a current of indoor air past a current of outdoor air so that heat moves between them. This allows the HRV or ERV system to recover the energy used inside the home to heat or cool the air and apply it to the incoming fresh air.
Imagine a hot day in summer (we know this is easy). An ERV or HRV system pulls in a current of hot, but fresh air from outside. As the hot air passes through the system, stale but cool air from indoors moves along it. The hot air loses heat to the cool air, lowering its temperature. The indoor air is exhausted outside, and the fresh air enters the house, pre-cooled so it won’t place extra pressure on the air conditioner. During cooler weather, the process reverses.
Heat and Energy Recovery Ventilators: Is There a Difference?
Yes, there is. For the most part, ERV and HRV systems run in the same fashion. What’s different is that the air currents moving through ERVs come into contact with each other, while in an HRV the heat moves through a heat exchanger and the air currents remain separate. What this means in practical terms is that ERVs allow moisture to move between the currents, so they allow for some levels of humidity control. The system that will best work for your home is something our technicians can help determine for you.
