Ventilation in winter always means a compromise: an open window brings in fresh air, but along with it comes the cold, which then has to be compensated for by additional heating. Most people simply avoid frequent ventilation during the cold season, sacrificing air quality for a comfortable temperature. A reversible ventilator solves this dilemma through heat recovery – a technology that allows extracting heat from the air leaving the room and transferring it to the fresh air coming in. A person does not need to choose between fresh air and warmth, as both tasks are solved simultaneously.
In tightly sealed apartments with energy-efficient windows, this problem is especially acute – natural air exchange through cracks is practically absent, so the air stagnates much faster than in older buildings.
How a reversible ventilator works
The operating principle is based on the cyclic alternation of two phases, which switch at a specific interval throughout the entire operation time of the device.
- exhaust phase – the device expels stale air outside, pre-extracting heat from it through a heat exchanger;
- supply phase – the collected heat is transferred to the fresh air entering the room, reducing the temperature difference.
Automatic mode switching occurs without human intervention – the controller itself determines the moment of phase change according to the set work cycle settings.
The duration of each phase is usually a few dozen seconds, so the transition between modes is practically unnoticeable to people in the room – only a stable, comfortable air exchange is felt, without sudden temperature changes.
Advantages of reversible ventilators
The continuous operation of such a device yields several practical results immediately, noticeable within the first few weeks of use.
- continuous supply of fresh air without opening windows;
- reduced heat loss in winter thanks to heat recovery;
- savings on heating by retaining heat in the room;
- improved air quality without stagnation or stuffiness;
- reduced humidity levels in the room;
- prevention of condensation on windows and walls;
- protection against mold caused by excessive moisture;
- no need to open windows even in freezing weather.
The combination of these advantages is especially noticeable in apartments with modern airtight windows, where natural ventilation through cracks is practically non-existent.
Models for different types of premises
Such a heat recovery ventilator can be installed either separately in each room or in combination with other exhaust fans to organize a full-fledged ventilation system for an apartment or house.
The microclimate of the room significantly stabilizes after installing the device – temperature and humidity remain in a comfortable range without the sharp fluctuations characteristic of simply opening windows.
