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
