- An HTHP uses refrigerants and compression ratios tuned for high lift. The trade-off is lower COP as delivery temperature rises — plan the duty with the heat pump selection calculation method.
- Process hot water and CIP loops. Low-pressure steam generation. Preheating in drying and evaporation, paired with an industrial waste heat recovery case.
- Delivery temp Typical COP 60°C 4.0–5.0 90°C 3.0–3.8 120°C 2.0–2.8
- Keep the waste-heat source above the minimum entering temperature and size the sink for the real process flow. For the wider recovery context, see heat pump waste heat recovery. An HTHP is the bridge that turns "too-cold-to-use" reject heat into saleable process energy.
あ high-temperature heat pump (HTHP) upgrades low-grade waste heat to useful process temperatures of 80 to 120°C, replacing steam boilers or direct electric heaters in industry. This article covers selection and integration.
