Thermal management – systems (HVAC) for the construction industry

Thermal management for construction vehicles

On the one hand, innovative thermal management helps construction vehicles to function perfectly even under the most demanding conditions. On the other hand, producers are faced with the task of providing optimal climate conditions for operators of off-road machines such as excavators, dump trucks, wheel loaders, cranes, mining and other special-purpose vehicles. This is a major challenge, especially in hot countries, i.e. in countries with high temperatures.

Challenges and solutions

Thermal management – systems (HVAC) for the construction industry

Our task is to ensure that the occupants of construction vehicles have optimal working temperatures and thus a pleasant working environment.

We offer well-thought-out thermal management and smart system solutions for optimising heat management and airflow in construction and commercial vehicles – intelligent, affordable and reliable. Robust construction, long service life and customisation are standard features of our HVAC systems. Depending on the area of application, we expect a service life of over 15,000 operating hours.

Krananlagen von Liebherr mit HVAC-System

Customer solution example

Problem:
Customer requests a HVAC system for their construction machine incl. the framework conditions to be taken into account (specifications)

Solution:

  • Plug & Play HVAC compact system with 4 mounting points to the cabin, 1x 24 VDC quick connectors and 1 low-volt quick connectors
  • Fully flashable software solution, UDS (Unified Diagnostic Services) diagnosable
  • Full integration into customer HMI (Human Machine Interface) via CAN-communication

Electrical rooms and power electronics

In the construction industry, not only drivers’ cabins need air conditioning. Electrical rooms and power electronics also require an innovative thermal management system that is appropriate for the environmental conditions. In case of individual requirements, we’re happy to support you with tailored, optimised solutions.

Our control systems provide climate comfort and additional noise reduction – a major challenge in the construction industry. When designing customised solutions, compliance with the required standards is a matter of course.

    Implementation and practice

    1. Feel-good climate

    An intelligent airflow system has a significant effect on the well-being of drivers in the cab. We consciously address

    • rapid warming of the foot area
    • rapid cooling in the head area
    • optimal temperature in the entire cabin

    2. Functional climate

    We use precise temperature control to prevent sensitive appliances from overheating. Reliable air conditioning protects the systems from failure and contributes to smooth operation.

    3. Humidity – Reheat

    Excessive humidity can sometimes cause safety and functional defects. On the one hand, the fogging of window panes in driver’s cabs no longer ensures safe driving or guiding, on the other hand, the humid air in control cabinets can cause controls and power electronics to malfunction.

    We’ll solve this problem with innovative heat management. Our HVAC systems extract both moisture and condensation where necessary to ensure safety and function.

    Parameters and standards

    Thermal management – systems (HVAC) for the construction industry

    In our HVAC systems, we take into account known parameters that we have gathered from years of experience in the construction industry, such as the insulation values of vehicle windows and walls or the behaviour of construction vehicle drivers.

    Physical factors and site, environmental and climate conditions also have an impact on the overall concept and are incorporated into the development process for thermal management solutions. As a system provider, we combine these metrics with our innovative approaches and our many years of expertise. This is how we create customer-specific, high-quality products that stand out.

    Customer solution example

    Problem:
    Customer requests a HVAC system for their tunnel drilling machine incl. the framework conditions to be taken into account (specifications)

    Solution:

    • HVAC compact system as a heavy-duty version with 1,000 VAC direct connection for the power supply
    • Transformer and AC/DC converter are integrated for supplying the power and low-volt components
    • Protective ventilation (over-pressure solution) of the cabin incl. filter system to protect against the ambient conditions in tunnel construction
