Why Thermal Cooling?

Cooling is becoming increasingly important with regard to global warming. Comparing the amount of energy used for heating and cooling worldwide, about 75% is being used for cooling, and only 25% for heating.

As scarce fossil energy resources are becoming increasingly expensive and burning them accelerates the global warming process even further, regenerative alternative energies are becoming more and more important. Conventional cooling technology, the so called compression refrigeration, is driven by electricity.

In addition, environmentally harmful refrigerants are being used which reach the environment through leakages and thereby boost the greenhouse effect.

In comparison, thermal cooling uses heat instead of electricity as the driving energy source, and water or ammonia are used as environmentally friendly refrigerants.
The following heat sources can be used as driving energy:

  • District Heating
  • Combined heat and power
  • Biomass
  • Process Heat

Advantages compared to electrically driven compression cooling technology:

  • Increased independence from public energy suppliers
  • Decrease in electricity usage and operation costs (electricity)
  • Stable cooling energy costs
  • Reduction of CO2 – emission by reducing the use of primary energy
  • Reduction of global warming potential (GWP) by using environmentally friendly natural refrigerants

Possible areas of application of thermal cooling:

Air-conditioning of buildings:

  • Public institutions
  • Shopping malls
  • Hospitals
  • Administration buildings
  • Banks
  • Hotels
  • Office buildings
  • Residential homes

Process cooling:

  • Pharmaceutical industry
  • Electrical industry
  • Printing- and media-industry
  • Food industry
  • Agriculture
    (i.e. Milk cooling,
    Piggery cooling)
