What does HRV stand for in HVAC terminology?

HRV in HVAC terminology stands for Heat Recovery Ventilator. This system is designed to improve indoor air quality while conserving energy. It works by transferring heat between incoming fresh air and outgoing stale air, allowing for better ventilation without significant energy loss.

During the winter, the HRV extracts heat from the warm, outgoing indoor air and uses it to pre-warm the incoming cold outdoor air, reducing the heating load on the HVAC system. In contrast, during warmer months, the HRV can help cool incoming air by transferring some of the heat from entering air to the outgoing air, maintaining a more comfortable indoor climate.

Understanding the function of an HRV is crucial for those involved in HVAC, as it plays an important role in energy efficiency and air quality within buildings.
