What is a recuperator: operating principle, types, ventilation features, humidity control and the role of the air conditioner in air quality

Operating principle and types of supply and exhaust ventilation
A recuperator — is a supply and exhaust unit with a heat exchanger that takes warm air from the room, transfers its heat to the cold outside air and returns the warmed fresh mass inside. There are active (rotary) and passive (plate) models. The switching or reversible design allows for alternating operation and high heat recovery efficiency of up to 90%.

Advantages and limitations of the supply and exhaust unit

• Retains heat or cold throughout the year in rooms
• Filters incoming air
• Maintains proper humidity and microclimate
• Operates quietly — up to 30dB
• Frost resistance: up to –35°C
• Limited performance depending on the model (150–500m³/h for household recuperators)
• Higher cost compared to simple supply and exhaust units

Recuperator — is a special heat exchange element of the ventilation system, which allows to reduce heat loss during air exchange in the room. Its main task is to transfer heat from warm exhaust air to cold supply air coming from outside. Thus, fresh air enters the room already heated, without requiring additional heating costs.

How does the supply and exhaust system control humidity and ventilation for the microclimate and air quality?

In mechanical ventilation systems, the heat exchanger is installed in the central module or in the air ducts through which fresh air is supplied to residential or office premises. Its efficiency is measured by the heat recovery index - the higher it is, the more energy is saved. Modern heat exchangers are often equipped with air quality sensors that automatically regulate the volume of air flow - usually from 50 to 200 m³ air per hour.

Domestic heat exchangers are convenient for apartments and small houses. They are compact, do not require a complex duct system, and are easy to install even in already equipped rooms. Their installation usually involves one opening in the outer wall, through which simultaneous ventilation and exhaust air are carried out.

It is also important to mention that the heat exchanger is a key element in reducing the temperature of the supply air in the summer, when warm outside air is cooled by the conditioned air in the room. Thus, with the help of a recuperator, you can not only preserve heat in winter, but also ensure effective comparison of costs in the off-season.
