ilmanvaihtorekisterit

Ilmanvaihtorekisterit are components within a building's ventilation system, specifically designed to modify the temperature of the incoming fresh air. They are often found in mechanical ventilation systems, including those with heat recovery. There are two primary types: heating and cooling registers.

Heating registers, often referred to as lämmitysvastus or lämmönvaihdin, use a heat source to warm the cold outside air before it is distributed into the building. This heat can be provided by hot water circulating through coils or by an electric resistance element. The purpose is to prevent a sudden drop in indoor temperature when fresh air is introduced, especially during colder months.

Cooling registers, or jäähdytysrekisteri, perform the opposite function. They use a cold source, typically chilled water or refrigerant, to lower the temperature of the incoming air. This is crucial for comfort during warmer periods, helping to reduce the cooling load on the building's air conditioning system.

The control of ilmanvaihtorekisterit is typically automated, managed by the building's automation system. Sensors monitor indoor and outdoor temperatures, as well as the desired indoor climate, to adjust the register's output accordingly. Proper maintenance, including cleaning and checking for leaks, is important to ensure efficient operation and air quality. Ilmanvaihtorekisterit play a significant role in maintaining comfortable and healthy indoor environments by ensuring that fresh air is introduced at an appropriate temperature.
