Summary

The refrigeration units used the polyalkylene glycol lubricant oil. As a result, dry expansion systems became possible, and the quantity of refrigerant in the system was remarkably reduced. Also, by using emergency safety systems, fully automated operation was made possible. A comparison of COP data between ammonia and R22 units, and between direct and indirect types, showed the ammonia expansion unit to be superior.
