Energy Recovery Ventilation: Fresh Air with Minimal Energy Loss

Energy recovery ventilation (ERV) systems are an essential component of HVAC systems, providing fresh air during minimizing energy loss. These systems are designed to exchange stale indoor air with fresh outdoor air, all whilst recovering and transferring heat or coolness from the outgoing air to the incoming air, thereby conserving energy and maintaining indoor comfort.

1. How energy recovery ventilators work in HVAC systems

Energy recovery ventilators function by utilizing a heat exchanger to transfer thermal energy between the outgoing and incoming air streams. This allows the system to extract heat from the warm indoor air during the colder months and transfer it to the fresh, cooler outdoor air. In the summer, the process is reversed, with the system extracting heat from the incoming hot air and transferring it to the cooler indoor air. This heat exchange process helps to regulate indoor temperature and reduce the load on heating and cooling systems.
