Konvekta CO2 heat pumps - Reliable, effi cient, cost-effective

For year-round heating and cooling of rail vehicles

Konvekta CO2 heat pumps are air-conditioning systems for rail vehicles, offering optimum comfort for personnel and maximum energy efficiency for vehicles.

A heat pump is tasked with getting the maximum from a fraction of the supplied energy to create greater heating comfort.
The system takes up to 75 % of its required energy (heat) from nature - i.e. from the surrounding air (COP = up to 4).

Furthermore, energy savings are achieved through:
• the natural refrigerant R744 (CO2)
• specifically developed components (e.g. heat exchanger)

Advantages

Up to 75 % of the necessary heat energy is extracted free of charge from the environment.
The system requires at most 25 % operating energy.
This means: up to 4 kW heating capacity is achieved from 1 kW battery energy = COP 4*

* COP = coefficient of performance
The ratio of the generated cooling or heating capacity to the electrical energy used

Cost and environmental saving potential - energy consumption

The heat pump reduces energy consumption,e.g. by 60 % at -10 °C when compared with classical electric heating systems.
When considered over a whole year, including air conditioning, energy requirements are reduced significantly.

Highly effi cient performance
The Konvecta CO2 heat pump is highly efficient: to generate 100 % heat, the heat pump always needs only a fraction of supplied energy (electricity).

The benefi ts of using CO2 as the refrigerant

R744 (carbon dioxide / CO2) is extremely suitable as an alternative to the current refrigerant R134a. CO2 (R744) is a natural component of air and has a greenhouse potential of only Factor 1.
Therefore, there are no legal restrictions for the use of CO2.

Economic benefits

  • reduced energy consumption
  • costs per kg refrigerant are around 90 % lower and are available for the long term
  • lower service charges /servicing times no recycling required, fewer components and simple, risk-free handling
  • no legal restrictions or limitations, long-term and permanently available

Environmental benefits

• sustainable and approved refrigerant
• non-flammable (R744 = fire extinguishing agent)
• non-toxic, no poisonous by-products or decomposition products
• no greenhouse effects
