Global Industrial Thermal Case Library

Currently featuring two author field-survey cases (Central China meat plants A & B, ammonia heat pumps). More anonymized references will be published as they are completed — not a substitute for site-measured delivery data.

See the equipment, then read exactly what the evidence supports

These references combine author field observations, photographs, and plant-reported outcomes. They are useful engineering evidence, but are not presented as independently metered performance.

Central China meat plant B: ammonia HP for plant hot water — coupling & ops lessons

Author field survey (2024-05): same ammonia HP architecture as plant A at a second Central China meat site; plant-reported ~200–300 m³/day hot water and ~¥100k/month steam savings, plus liquid-path and cleanliness lessons.

Industry: Food
Source temperature: 28–35°C
Sink temperature: 50–70°C
Temperature lift: ≈ 15 K
Architecture: Ammonia mid-temperature heat pump; liquid drain should enter the auxiliary receiver (winter oil-cooler feed) rather than only the main receiver
Result status: Overall operation reported as good; plant continues to displace purchased steam for hot water
Key risk: First-year oil change; shaft-seal leak monitoring; installation cleanliness (strainer impurities); plant suggestion of a discharge-header sensible-heat exchanger (80→65°C ammonia / free water lift) is unverified

Central China meat plant A: ammonia HP recovers refrigeration heat for plant hot water

Author field survey (2024-05): ammonia mid-temp heat pump coupled to the plant refrigeration train via preheater + condenser-evaporator; plant-reported ~400–500 m³/day hot water displacing purchased steam.

Industry: Food
Source temperature: 28–35°C
Sink temperature: 55–75°C
Temperature lift: ≈ 20 K
Architecture: Ammonia mid-temperature heat pump coupled to live refrigeration via preheater + condenser-evaporator + auxiliary receiver liquid path
Result status: Overall operation reported as good; steam purchase displaced for a large share of plant hot-water duty
Key risk: First-year oil change mandatory for the surveyed lubricant grade; piping cleanliness; prefer skid-packaged preheater + condenser-evaporator for future builds
