How HRV Systems Work

HRV systems operate using a heat exchanger to transfer heat between outgoing and incoming air streams, ensuring efficient energy use. The system comprises several key components, including the heat exchanger, fans, and ducts. Fresh air is drawn in from the outside by one fan, while another fan expels stale indoor air. As these air streams pass through the heat exchanger, heat from the outgoing air is transferred to the incoming air, warming it without mixing the two streams. This process allows the home to retain heat while ensuring a continuous supply of fresh air.

The ducts are strategically placed throughout the home to distribute fresh air evenly and remove stale air from areas where it tends to accumulate, such as kitchens, bathrooms, and utility rooms. The system also includes filters to remove particulates from the air, ensuring that the air being circulated is clean. Controls are used to adjust the airflow and manage the operation of the HRV system, allowing for customisation based on the occupants’ needs and the external environment.

In some models, sensors monitor humidity levels and automatically adjust the airflow to maintain optimal indoor conditions. This automatic adjustment is particularly useful in preventing the buildup of moisture, which can lead to dampness and mould. Additionally, some HRV systems come equipped with bypass mechanisms that allow for direct ventilation without heat recovery when conditions are favourable, such as during mild weather.

Overall, HRV systems function to maintain a healthy indoor environment by continuously supplying fresh air and expelling stale air while conserving energy through heat recovery. This makes them an invaluable addition to modern homes, promoting both comfort and efficiency.
