How HRV Air-Conditioning Works

HRV air-conditioning systems facilitate heat exchange between incoming and outgoing air streams, achieving a balance between temperature and air quality indoors. The process begins as fresh air is drawn into the building from the outside. Simultaneously, stale indoor air is expelled. Within the HRV unit, these two air streams pass through a heat exchanger. This component allows the outgoing air to transfer heat to the incoming fresh air without the two streams mixing directly.

The pre-warming or pre-cooling of incoming air significantly reduces the load on traditional heating and cooling systems, which means less energy is required to maintain a comfortable indoor climate. In colder months, the heat from the outgoing air is used to warm the incoming air, reducing the need for additional heating. Conversely, the system can help cool the incoming air in warmer months by expelling the cooler indoor air.

Filters within the HRV system ensure that the incoming air is clean and pollutant-free, enhancing indoor air quality. The continual exchange process saves energy and maintains a healthier and more comfortable living or working environment.
