Hrv how does it work

With these two separate airstreams in the system, they cross paths and a heat transfer occurs between them. Following the heat transfer, the stale air from inside your home is now cooler and is deposited outside. Meanwhile, the fresh air is now warmer and is supplied to the home.

Through this transfer, there is no energy wasted and your home is kept comfortable. Similar to bathroom fans, HRVs can be set to run on high with a bathroom timer. It is recommended to set the HRV on high for the maximum time 60 minutes any time the shower or bath is used to provide optimum removal of moisture. What makes an HRV unique and energy efficient is that it uses heat transfer to ensure that the air being supplied to the home is a comfortable temperature.

This heat transfer is done without the two airstreams ever mixing; ensuring that you only have fresh air being supplied to your home. Email Address. Email: info avonelectric. View Privacy Policy. Introduce fresh, dry, warm air. Transfer available heat from stale, damp, exhaust air to preheat fresh incoming air.

Reduce condensation, mould, mildew, etc. Stale, humid air is exhausted from the house. Clean, fresh, outdoor air is supplied to the house. Both processes occur simultaneously.

Exhaust stale humid polluted air Replace stale indoor air, with dry, pre-warmed outdoor air. Transfer available waste exhaust heat, to incoming fresh air.

Help create a more even temperature throughout the home. Save up to 5 times more energy than it costs to run. Reduce greenhouse gas emissions, by recycling energy. Avon Electric Ltd.

For these reasons, virtually every building built would benefit from a balanced, mechanical, fresh air HRV or ERV system — and the more airtight the building, the better that system will perform.

We know where incoming air is coming from: a clean, filtered intake leading directly through the HRV or ERV, delivering healthy fresh air, comfortable interior temperatures, and a smaller carbon footprint. Exhaust air is 1 drawn from kitchen and bathrooms where odors and pollutants collect, 2 passes through the heat exchanger where it shares its thermal energy with intake air, and 3 is exhausted to the outside.

The two air streams — fresh intake air and stale exhaust air — never mix.
