High-temperature heat pump (HTHP)
A heat pump captures low-temperature heat (below 60°C) and raises it to a temperature that is useful for the plant, generally in the form of hot water. At high temperatures, the HPP can supply applications up to a maximum of ~100°C (demonstrators exist to push this higher depending on the fluid and compressor).
Hybrid heat pump + MVR system
– Fewer HVAC floors,
– Reduced CAPEX,
– High overall COP.
On industrial sites, FE units show overall COPs > 4 and, for the HVAC part alone, double-digit COPs.
When to choose HTHP alone, MVR alone, or HTHP + MVR ?
• Heat pump only:
Requirement limited to hot water with temperatures below 100°C
CAPEX and footprint optimization
Low thermal power (below 5MW)
• MVR alone:
Need for “high” temperature steam (above 100°C)
High thermal power (from 1 MW)
OPEX optimization
• Heat pump + MVR:
High final requirement (e.g., 150°C) with “cold” source (e.g., 50°C)
Heat pump for “low” temperature (fewer MVR stages),
MVR for final high pressure
Optimized CAPEX/OPEX (combination of CMV and heat pump advantages).
