Domestic heat exchangers types

It is easy to notice that heat exchangers in homes are becoming more and more popular – thanks to lower prices and increasing efficiency, many people decide to use such a solution. Heat exchangers are divided into cross, counterflow and rotary heat exchangers.
How does the process of heat exchange in cross-flow heat exchangers work?
The device has a simple casing made of aluminium, steel or plastic plates. The efficiency of heat recovery is between 60% and 80%. The exhaust air is not directly in contact with the supply air – most often the supply air is separated by a wall. When the temperatures in the air streams differ, the heat of the air at a higher temperature is transferred through a separating barrier to the lower temperature stream. This means that the hot exhaust air that is extracted transfers its temperature to the fresh cold supply air. If you are interested in cross-flow heat exchangers, check out this offer.
Counterflow heat exchangers in the housing
These devices are much more expensive than cross-flow heat exchangers, but they are very popular in single-family houses. Continuous modernization of the equipment has led to the improvement of the construction. This resulted in the creation of counter-current spiral heat exchangers, which do much better in negative temperatures. The offer of such devices can be found on the website – counter-current in-casing,156,
Rotary heat exchangers
Rotary devices are used less frequently in apartments – it is connected with higher price. Such a heat exchanger is usually made of smooth aluminum foil, creating sets of channels for airflow. The process of heat exchange in this type of exchangers takes place by absorbing the temperature of extracted air from the room, which flows through the device, heating it. The exchanger rotates and fresh air flows through the other side of the exchanger, absorbing the temperature from the first part of the device. A big advantage of this solution is the efficiency of about 90%. Using such heat exchangers in homes will certainly bring many benefits, which will significantly improve the comfort of our well-being. They will significantly reduce heating costs and improve the quality of air in your home.
