The SNDC Design Office, dedicated in developing HVAC systems for vehicles and self-propelled machines, is specialised in:
- thermal applications
- aeraulics
- electrical and mechanical system integration
Preliminary
study
Starting from the customer’s specifications, the SNDC Design Office produces a thermal assessment using modelling software, as well as a layout study to optimise the system’s architecture and dimensional characteristics.
Thermal and aeraulics modelling
The
SNDC Design Office uses modelling and dimensioning resources to
define the refrigerating and calorific capacity and air flow
required for the mobile air conditioning unit.
Thermal modelling takes several parameters into consideration to calculate the exchanges between the machine’s cab and its environment: outside temperature, hygrometry, wind speed, geographical operating area, surface area, orientation, colour, thickness and thermal conductivity of walls and windows, air renewal rate in the cab and required temperature.
Mechanical
design
The SNDC Design Office development process includes a 3D modelling (CAD) phase to model the components and the system in their environment.
Modelling the parts allows for checking the system integration (interference with moving parts, maintenance accessibility, etc.) and is used to produce part and component 2D drawings for manufacturing purposes.
Prototypes and tests
The completion of tests is a key phase for the development and tuning of an HVAC system. One or more prototypes are developed and qualified with the customer being present in the SNDC test rooms.
