Use natural refrigerants

The air conditioning system

In recent years，In order to achieve green travel，Railway industry continues to upgrade iteratively。Liebherr is committed to replacing traditional refrigerants with environmentally friendly refrigerants，And apply it to the air conditioning system.。Three of these technologies are particularly eye-catching.：Carbon Dioxide、Use of propane as an alternative refrigerant，As well as the mature use of air circulation technology。

Liebherr air cycle air conditioning systems use only ambient air for cooling

——No refrigerant is required

The global warming trend parameter for CO2 is 1，Compared to conventional refrigerants，It not only has low greenhouse effect performance,，And achieve high energy efficiency in temperate climates.，While providing efficient heating in heat pump mode。

 

Natural refrigerant propane (R290) Sustainable application in refrigeration field，The pressure aspect is also related to the present.R134 refrigerant approach。Consider all safety requirements such as refrigerant flammability，The corresponding technical concept was developed by Liebherr andTÜV SüdJoint research and development。

Air conditioning system using carbon dioxide refrigerant

Liebherr's air circulation technology is a pure environmental solution。It uses only natural air for cooling.-No refrigerant is required。Liebherr was one of the first companies to start using this technology on rail vehicles.。

MACS 10.0 -

Module with flexible cooling capacity

Highly standardizedMACS 10.0 Modular Air Conditioning System

Liebherr'sMACS 10.High standardization of modular air conditioning systems，Features of lightweight and miniaturization。 Many MACSModules can be flexibly installed on the vehicle depending on power requirements and location，Thereby ensuring energy conservation and consumption reduction.。

Digital development

And intelligent operation and maintenance

Liebherr specialises in system simulation and digitisation，Through the use of digital development methods and digital networks throughout the value chain，Reduced development time and optimized product。The cases displayed at the exhibition are“Hardware in the loop”Test Bench:By remote control system and webcam，Each air conditioning unit can be controlled in real time，And monitor its running state in real time.——Existing data monitoring，There is also intuitive monitoring.。Liebherr demonstrated Berlin to Kolchenburg(Austria)Interactive transmission of control signals and network camera images of the test bench。

 

Liebherr also makes maintenance more time-saving and cost-effective with digital solutions in the area of intelligent operations.。Liebherr Troubleshooting WizardTSAIs an appapp，Provide effective support for problem identification and resolution。The potential of the application and its benefits to operators will be demonstrated in action at the show。

Flexible for road and rail
