As part of a volunteer project, an air conditioning system is being integrated into the decommissioned Tupolev Tu-134 at the Finowfurt Aviation Museum. The aim is to air-condition the interior using the existing, original ventilation ducts. Visible interior units are deliberately omitted in order to preserve the historic appearance of the aircraft.

Objective
The primary purpose of air conditioning is to preserve the substance of the aircraft. The effects of the weather and the build-up of moisture in the interior cause the furnishings and structure to deteriorate. Targeted dehumidification significantly slows down this deterioration.

Technical challenge
Installing a commercially available ducted air conditioning unit with a split external unit in an aircraft that is not designed for such a retrofit. The aerodynamic shape – with predominantly curved surfaces – makes it difficult to position the rectangular system components.  

Solution approach
The choice fell on a ducted air conditioning unit, the air routing of which had to be adapted for integration into existing ventilation systems. The outdoor unit is positioned in the former turbine housing. This provides sufficient protection from the weather and allows adequate heat dissipation without changing the external appearance of the machine.

Implementation
After a detailed inventory and technical planning, the installation locations were defined, brackets prepared and the electrical supply technically clarified. The installation work began promptly in close coordination with the museum’s technicians.
