Indian Industrial High-Temperature Heat Pump (HPHT) — IEA HPT TCP Task 32/51 + EHPA + BEE PAT

Indian industrial HPHT (2 MWth at 120°C for textile drying) demands ₹147 Cr capex with R600 cascade + buffer tank + plate HX — saves ₹1.1 Cr/yr vs gas boiler + 5-7 yr payback. IEA HPT TCP Task 32/51 + EHPA HTHP + BEE PAT + ECBC 2024 + Kigali govern. India HPHT market 1 % (2024) → 5 % (2027 target). Three failures: waste-heat source not characterised needing thermal-storage, R134a still specd without HFC phase-down compliance, process integration not analysed via pinch losing 30 % theoretical.

Indian industrial high-temp heat-pump (HPHT) framework

India industrial HPHT (High-Temperature Heat Pump) — emerging market for textile drying + food processing + paper + dairy + chemical at 80-150°C. Players — Star Refrigeration + Bock + Mayekawa + Mitsubishi Climaveneta + ENGIE Refrigeration. Standards stack — IEA HPT TCP (Heat Pumps Technology Collaboration Programme) Task 32 + 51 + EHPA HTHP + Industrial Heat Roadmap 2050 + BEE PAT industrial + ECBC 2024 industrial + worldreknown DECARB platform.

Industrial HPHT MEP scope — 2 MW thermal at 120°C for textile drying

Three Indian industrial HPHT MEP failures

1. Heat source (waste-heat) not characterised — HPHT requires consistent 20-40°C heat source. Indian industrial waste-heat often intermittent. Specify thermal storage + heat-rate analysis per IEA HPT Task 51.
2. Refrigerant selection ignores HFC phase-down — R134a + R407C used in many HPHT designs. Kigali phase-down forces R600 + R290 + R744. Specify natural refrigerant per EU F-gas + India ICAP.
3. Process integration ignored — HPHT works best with process-load matching. Indian projects often retrofit HPHT to existing boiler without process integration — get 60-70 % theoretical performance. Specify pinch analysis per Linnhoff + BEE PAT VII.
