For many years mechanical and natural ventilation systems have developed separately. At the same time the demands for energy saving in mechanical ventilation are rapidly growing, forced by the shortage of resources. Respectively, this compels engineers to turn back and check what was missed in the process of significant costs reduction. Naturally, this leads to the next step, which is development of ventilation concept utilizing and combining the best features from each system to create a new type of ventilation system – Hybrid Ventilation.

Analysis of the possibilities for energy recovery through recuperation in the ventilation and air conditioning systems.

It seems the discussion for the necessity of energy recovery systems is over not only in Western and Northern European countries, but also in Bulgaria. For the people who made serious effort for convincing and proposing legislative changes in the last 20 years, it is a real success. Today it is rare to see a ventilation or air conditioning project without energy recovery (recuperation or regeneration).

The economic pressure (rise of energy prices) surpassed the legal regulations. Designers and investors reacted more adequately than the legislators.

The next important step is the choice of the right energy recovery system. The right choice means a cost-effective choice that doesn’t compromise the microclimate.
