Sanyo

Certificates & Compliance: Refrigerant Eco-Friendliness: NH₃ (GWP=0)/R290 (GWP=3), compliant with EPA SNAP Rule 23
Carbon Footprint: Annual CO₂ reduction of 142 tons (equivalent to planting 3,200 trees)
Certifications: USDA Organic + ENERGY STAR Refrigeration System

Brewing Impact: Dry-hopping at -1°C±0.2°C → α-acid retention >93% (vs. 76% conventional)

Technical Basis: CO₂/NH₃ cascade system has a COP of 4.2 compared to a single-stage system of 2.8. The system features PID-controlled glycol valves and redundant compressors, with temperature control within ±0.3°C during critical metabolic periods (to avoid heat stress). The R290 turbine plate commutation speed is 3.5 m/s (compared to a conventional 1.2 m/s).

CO₂/NH₃ Cascade System (-45°C): Low-temperature stage: CO₂ (evaporation at -45°C) rapidly cools fermenters, addressing yeast heat stress. High-temperature stage: NH₃ (-10°C) cools malt, a GWP=0 environmentally friendly working fluid. Energy efficiency mechanism: Staged compression reduces overheating losses, achieving a COP increase of 40%.
Solar-Assisted Absorption Chiller: Heat recovery: Solar panels (120 square meters) drive lithium bromide chillers.
Free cooling capacity: ≥15% cooling capacity is provided in summer, and the utilization rate of Nanka's sunlight resources reaches 83%.

Precision Dry-Hop Chamber (-1°C±0.2°C): Aroma Retention: -1°C ambient temperature suppresses monoterpene volatilization, achieving >93% alpha-acid retention.
Control Solution: Dual compressor hot standby + electronic expansion valve PID control.
R290 Turbo Plate Exchanger: Turbulent design: Plate corrugation angle increased from 60° to 30°, increasing flow rate by 192%.
Safety measures: Explosion-proof motor + infrared leak sensor, compliant with NFPA 36 standards.

Brewery Energy Management Platform: Load Forecasting: Dynamically adjusts cooling capacity based on fermentation curves and weather forecasts.
Fault Prediction: Vibration sensors provide early warning of compressor anomalies (≥72 hours in advance).
Remote Operation and Maintenance: 80% of faults are diagnosed in the cloud, reducing on-site service costs by 40%.
