Flash Electrical conducted a power consumption comparison between an LCPR NH₃ refrigeration system and a conventional NH₃ system. The assessment was based on facilities with a storage volume of approximately 30,000 m³.

Average Daily Power Consumption

• Conventional NH₃ system: 6,612 kWh per day
• LCPR NH₃ system: 3,308 kWh per day
• 
  

Key Findings

The results show that the LCPR system consumes approximately 50% less electricity than the conventional NH₃ system, making it roughly twice as energy efficient.

Additional Efficiency Benefits

The LCPR system may deliver even greater efficiency gains when the additional refrigeration load that occurs during system start-up is taken into account. Under these conditions, overall efficiency could be at least 12% higher than indicated by the base comparison.

Estimated Annual Savings

Based on an electricity price of $0.30 per kWh, the estimated savings are calculated from the difference in average daily power consumption between the conventional NH₃ system and the LCPR NH₃ system.

• Daily energy saving: 3,304 kWh
• Estimated daily cost saving: $991.20
• Estimated annual cost saving: $361,788
• 
  

Basis for Comparison

The comparison is based on two facilities with similar characteristics:

• Both stores were constructed in the same year.
• Both use compressors manufactured by the same supplier.
• One store operates an LCPR NH₃ refrigeration system.
• The other operates a conventional NH₃ refrigeration system.
• 
  

These comparable conditions provide a reliable basis for evaluating the difference in energy performance between the two systems.
