Industrial refrigeration energy audit checklist
Connect load, condensing, evaporators, defrost and infiltration before estimating savings.
This pre-audit checklist keeps product temperature, food safety, redundancy and operating constraints visible while screening refrigeration opportunities.
Compressor kW, suction and discharge conditions, condensing temperature, fan/pump status and sequencing.
Evaporator approach, defrost timing, airflow, ice condition, infiltration and low-temperature zones.
Normalize electricity against production, weather and temperature-zone requirements.
Use ambient and heat-rejection limits; do not apply a fixed percentage without operating-hour data.
Review compressor staging, suction reset, evaporator demand and minimum stable operating limits.
Separate avoidable door load, defrost heat and fan operation from core product refrigeration.
Trend compressor power, suction/discharge conditions, ambient, room temperature, production and control status before and after changes.
