Heat recovery is an essential element of modern buildings, ensuring fresh air indoors and energy savings. Choosing the right heat exchanger is crucial for its effective operation. In this article, we will look at different types of heat exchangers and their parameters.
Why is heat recovery important?
Heat recovery, i.e., the recovery of heat from the air exhausted from a
building, leads to significant heating cost reductions. Modern homes are
increasingly better insulated, which is advantageous in terms of energy
savings. However, it can lead to problems with indoor air quality. Heat
exchangers solve this issue, providing a constant supply of fresh air and
simultaneously heating it with heat from the exhausted air.
Types of heat exchangers
Not all heat exchangers are the same. Here are some of the most popular
types and their characteristics:
Counterflow heat exchangers
In these devices, two air streams (external and internal) flow side by side
in opposite directions. This allows very effective heat transfer between them.
Counterflow heat exchangers are among the most efficient on the market.
Crossflow heat exchangers
In this case, the two air streams flow side by side in the same direction.
They are less efficient than counterflow exchangers but have other advantages,
such as a simpler structure and lower price.
Rotary heat exchangers
Here, the exhausted air stream rotates, transferring heat to the supply air
stream. They are very efficient and can operate over a wide temperature range.
Heat exchanger parameters
When choosing a heat exchanger, several key parameters should be considered:
1. Heat recovery efficiency - This indicates how effectively the device can recover heat from the exhausted air. The higher the efficiency, the greater the savings.
2. Power - Specifies the space the device can handle. It's essential that the heat exchanger's power matches the building's needs.
3. Noise level - Nobody wants a noisy device in their home. It's worth considering this parameter before purchasing.
4. Price - Although heat recovery leads to long-term savings, the initial expense can be significant. Consider how much budget can be allocated for this purpose.
Conclusion
Heat recovery is an excellent solution for those who want to live in a healthy environment and save energy. Choosing the right heat exchanger is key to reaping these benefits. By understanding the different types of heat exchangers and their parameters, we can make an informed choice that will bring us maximum benefits.
