The baseline specifications and parameters chosen are shown in Table 1. However given their use in high-power industrial applications these designs are often proprietary. Ammonia thermosyphon design.
Ammonia Thermosyphon Design, Features When a refrigerating compressor unit is used in the refrigeration system a thermosiphon liquid receiver is required to separate the refrigerating medium from return-gas in oil condenser. When designing a thermosyphon oil cooling system one usually begins with the design oil cooler heat rejection and an assumed refrigerant overfeed rate say 41. However given their use in high-power industrial applications these designs are often proprietary.
