Mechanical Compression Heat Pump

Conversion of residual heat into usable process heat

Heat Pumps/Heat Transformers/Steam Recompression

Technology description

Siemens provides complete heat pump systems in the range 5-50 MWth for higher temperatures up to 160 °C  using a working fluid suitable for higher temperatures that is inherent save to ensure limited safety precautions & permitting requirements.

Key features

  • Medium: sustainable type (New fluids e.g. non flamable, non toxic, non GW)
  • Capacity Heatpump 5-50 MWth
  • Temperature range 10-150 C or higher in case of open system such as steamcompressors

Application fields

Potential heat sources: 10-100 °C:

  • Cooling water
  • Liquid condensate
  • Heat from chiller condenser
  • Wet air from drying
  • Heat from chemical reaction
  • Heat from electrolyzer
  • District heating

Potential heat sinks: 90-150 °C:

  • Hot air for drying
  • Hot process water
  • Hot air for drying
  • District heating
  • Product processing

Business case

By re-using restheat as source to generate hot water and/or 5 bar steam, an industry can reduce or avoid its consumption of natural gas.

CO2 impact / Energy cost reduction

  • Avoidance of fuel

Non-energy benefits

Technology deployed by

  • Siemens delivered 50 large scale Heat Pumps ranging between 5-30MWth., including execution & service contracts since 1980s.
  • Heat pump conversion into worlds largest cooling machine in 2013.
