In HVAC systems, what does HRV stand for?

In HVAC systems, HRV stands for Heat Recovery Ventilator. This component is essential for improving indoor air quality while maintaining energy efficiency. An HRV functions by transferring heat from the outgoing stale air to the incoming fresh air, which helps in conditioning the indoor space without excessive energy loss.

During winter months, the HRV captures the heat from the air that is being expelled, warming up the incoming cold air, which reduces the load on heating systems. Conversely, during warmer months, it can help cool incoming air by transferring heat from it to the outgoing warmer air. This heat exchange process ensures that ventilation occurs without sacrificing energy retention, making HRVs a vital part of energy-efficient HVAC solutions.
