HRV and ERV Explained
Understand the recovery-core distinction before selecting fresh air equipment.
Sensible and Total-Energy Recovery
HRV refers to sensible heat recovery. ERV can transfer both sensible heat and moisture through an appropriate total-energy recovery medium. Confirm the core or wheel type for the selected model.
Winter and Summer Operation
In winter, recovered heat can preheat cold incoming outdoor air. In summer, energy from the cooler exhaust air can pre-cool hot incoming outdoor air. The result depends on the operating conditions and the selected equipment.
Single-Flow Is a Different Product
A single-flow fresh air unit supplies filtered outdoor air using one supply fan. The supplied product range describes it without a recovery core, so it should not be presented as an HRV or ERV.
