Sorption-supported air conditioning

The comfort air conditioning is based on the principle of air dehumidification and cooling by means of a liquid sorptive agent and heat as the drive energy. This is called sorption-supported air conditioning. Since low temperature heat can be used as drive energy for the air dehumidification, various heat sources, e. g. solar thermal plants and district heat networks, and types of exhaust air recovery, e. g. combined heat and power plants, can be used efficiently.

This technology offers the possibility to store heat in a liquid medium nearly without loss of temperature and for a nearly unlimited period of time. Particularly in the case of non-constant heat offerings, e. g. solar energy, the stored heat can be used sustainably, allowing for an increase of the degree of efficiency.

Advantages

  • Different heat sources may be used, like return air
  • Low operating costs due to e. g. heat recovery and excellent maintenance concepts
  • Storage of heat energy without losses
  • Low regeneration temperatures of about 55 – 70°C
  • Cooling without cooling agents
  • Reduction of the CO2 output required for air conditioning
  • Representatives, sales and service throughout Europe from a single source
  • Energy efficient operating concepts (e. g. very high coefficients of efficiency) lead to very low energy costs
  • Air conditioning without summerly peak load by usage of electrical energy
  • Constant heat requirement all-the-year
  • Thermal powered refrigeration with COP>1
 
 

Cooling by indirect evaporative cooling and sorption-supported air dehumidification

Cooling without current, water is sprayed into the return/exhaust air of the plate heat exchanger. The resulting evaporation of water withdraws heat from the outside air, temperature reductions of more than 10 K are possible. Additional dehumidification of outside air with sorption system

Nominal air output: 2,500 m3/h – 15,000 m3/h

That´s how it works:
