Introduction to heat driven (adsorption) cycles

Adsorbents:

  • SILICA GEL  Low temperature lift
  •  ZEOLITES     Low pore volum High temperature lift
  •  CARBONS     High pore volume, Medium lift

Applications:

  • Heat pumps
  • Refrigerators
  • Air conditioning

Driven by heat from:

  • Fossil fuels
  • Bio fuels
  • Waste heat
  • Solar thermal energy

Refrigerant requirements:

  • High latent heat per unit volume
  •  Chemical stability
  • Pressure between 1 and 5 bar
  •   Non polluting

Main contenders:

  •  Water
  • Methanol
  • Ammonia
