How Heat Recovery Ventilation Unit Operates?
At the heart of heat recovery ventilation unit lies a core technology known as the heat exchanger. This component is pivotal in operating these systems, enabling heat transfer from outgoing, stale air to incoming, fresh air without the two air streams directly mixing. The process begins when the indoor air, warmed by the building’s heating system and the occupants’ activities, is drawn out of the building through the unit.
Simultaneously, cold, fresh air from outside is brought in. As these two streams pass through the heat exchanger, the warmth from the exhaust air is captured and transferred to the cooler incoming air. This mechanism ensures that the energy used to heat the indoor air is maximally utilized by pre-warming the fresh air before it circulates into the living spaces. As a result, the heating system doesn’t have to work as hard to maintain the desired indoor temperature, leading to reduced energy consumption and costs.
It’s important to note that despite the proximity of the outgoing and incoming air streams within the heat exchanger, they are kept separate to prevent cross-contamination. This design allows the system to maintain high indoor air quality by replacing stale indoor air with filtered, fresh air from outside. Heat-recovery ventilation units achieve their goal of providing energy-efficient, comfortable, and healthy indoor environments through this sophisticated yet straightforward process.
