What does ERV stand for?

ERV stands for Energy Recovery Ventilation. This refers to a system designed to improve the efficiency of air exchange in a building while minimizing energy loss. Energy Recovery Ventilation systems work by transferring heat and humidity between incoming and outgoing air streams. This means that during winter months, the outgoing warm air can precondition the incoming cold air, and during summer months, the outgoing cool air can help cool the incoming warm air.

By using an ERV, buildings can maintain indoor air quality while reducing the energy load on heating and cooling systems, leading to greater efficiency and potential cost savings on energy bills. The use of ERV systems is particularly important in tightly sealed buildings where fresh air exchange is limited, as they allow for adequate ventilation without compromising energy efficiency.

Other choices such as Effective Recovery Ventilation, Enhanced Relative Ventilation, and External Radial Ventilation do not accurately describe the process or the technology associated with energy recovery in ventilation systems.
