Boomerang is a free service from Eberspaecher Kalori. It involves sending back a modeled cab, with multiple alternative solutions for the integration of standard or specific components.
Why is it called Boomerang? Because once users have sent a model of their cab to the design office of Eberspaecher Kalori and, like a boomerang, they send it back almost instantly, fitted with a HVAC system and its accessories. Rapidity takes nothing away from the serious intent of this concept. The technical solution is fully costed. Often, multiple solutions can be offered, and the final decision is up to the user.
If the solution seems to be too simplistic, users should think of the number of times they have drawn up, or financed, a HVAC system, which finally ended up very similar to existing solutions, said the company. Eberspaecher Kalori’s offers a catalog with proven solutions covering a range of site machinery or agricultural vehicles.
In addition to this, the expertise of the Kalori design office, supported by thermodynamic calculations carried out using the specially designed Simulka software, help to inform installation designs.
“The majority of the time”, stated Frédéric Ferreira, Systems Consultant in the design office, “we can instantly identify the solution which will be chosen. After the verifications by calculation, we can rapidly point the manufacturer towards a reliable offer in terms of performance, and a highly efficient one from an economic standpoint”.
To optimize the performance of an air conditioning system, the manufacturer has to set aside enough space as the equipment takes up considerable room. There is a story of wise old man, who shows his students that to put sand, gravel, and pebbles in a jar, you need to start with the pebbles.
The HVAC unit and the air diffusion ducts are the same large pebbles, but in a vehicle. So the HVAC system must be chosen before starting selecting smaller components. This will ensure optimum performance levels in terms of comfort, and avoid undesirable outcomes, such as lack of cabin space which is a cause for user dissatisfaction. In an air-conditioned vehicle a certain level of comfort is expected, especially when the weather is hot.
These HVAC systems available meet certain dimensions restrictions, so they can be installed in a dashboard under a bench seat, or even within a low-level roofing space. When required by specifications, pressurization systems (meeting the requirements of EN15695 – Class 4) can be integrated into the cab. HVAC control can be automatic or manual via the CAN network using the company’s Kanbox, or controlled mechanically using cables. The Kanbox is an electronic unit to pilot through CAN network the Kalori heating and air conditioning systems. It supports CANopen and J1939.
