Comparison of the effectivity of
heat recovery systems
Changing legal determining factors as well as growing energy costs and an increasing dependence on external energy supplies make increasingly important to build energy efficient buildings.
The employment in Germany of the most commonly installed heat recovery systems (circuit compound systems, rotary heat exchangers, and plate heat exchangers) has contributed to the improvement of energy efficiency in building for several decades now.
Using the example of an air conditioning plant near Stuttgart with an outside air exchange of 50,000 m³/h we have compared the effectivity of these three systems with each other.
Conclusion of our studies:
In regards to business and economic criteria, rotary heat exchangers (rotorsystems) offer special advantages. Thanks to their special construction and function principle operational as well as investment costs can be lowered by a great degree. The unique efficiency of rotorsystems meets the requirement the best to reduce the demand for primary energy to a minimum.
