Pleasant working climate thanks to efficient hall cooling: LINZ AG LINIEN relies on adiabatic cooling from merlin^®

Maintaining a pleasant indoor climate in industrial workshops is an increasing challenge in the summer months. LINZ AG LINIEN uses merlin^® ALPHA high-pressure atomization for adiabatic hall cooling in its central workshop, where 39 employees are responsible for the maintenance of over 108 buses and other vehicles from the entire LINZ AG fleet. The adiabatic cooling system is used in summer, as the temperature in the hall rises increasingly on hot summer days. The roof work stand directly under the hall roof, where maintenance work is carried out on the bus roofs, benefits in particular from the cooling.

Necessity due to higher temperatures
"Summers are getting hotter every year - this has increasingly changed the working conditions in the workshop," explains Alexander Zehentner, head of the bus and vehicle workshop. The use of a conventional air conditioning system was out of the question, particularly due to the structural nature of the hall: "Due to the structural conditions and the size of the hall, conventional air conditioning was out of the question economically. We therefore specifically looked for an energy-efficient and cost-effective alternative."

Since commissioning, the indoor climate in the workshop has improved noticeably. "Our employees work in much more pleasant indoor climate conditions - this has a positive effect on the quality of work and motivation," emphasizes Alexander Zehentner.

The system is in operation all year round: In summer, it reliably provides cooling, while in winter it humidifies the air as required to ensure a consistently pleasant indoor climate. A positive side effect: the high-pressure atomization ensures effective binding of dust particles. "We are very satisfied with the cooperation and project management of merlin^® , the installation was uncomplicated," summarizes Zehentner.

Technical information:
A merlin^® ALPHA high-pressure atomization system controls six zones in the LINZ AG LINIEN hall, each of which is monitored by its own humidity sensors. The total atomization capacity is over 1,262 l per hour and corresponds to a cooling capacity of 900 kW per hour with a power consumption of 6 kW per hour.
