The document discusses a survey of refrigeration installations using natural refrigerants NH3 and CO2 at cold storage facilities. It describes a 200,000m3 cold storage/logistics center project that installed 11 refrigeration packages using NH3 and CO2. The packages provide a total cooling capacity of 2700kW and achieve an estimated 25-30% reduction in energy consumption compared to previous systems using HCFC-22. The system offers advantages including use of natural refrigerants, improved energy efficiency, safety features, low maintenance needs, and automatic operation.

CONCLUSION :
This survey of NEWTON in Cold Storage installations,
using natural refrigerants NH3 and CO2,
initially developped to reduce the environmental load,
show that :
compared to HCFC-22 power consumption savings
with NEWTON are achieved of 25 to 30%.
