Design and selection of ice machines

Issues regarding the design and selection of ice machines (ammonia compressors) for ammonia synthesis, particularly how to determine the amount of gaseous ammonia that the ice machine can handle Cooling capacity? Thank you all
The standard steps for selecting a chiller are as follows: 1. Determine the theoretical cooling capacity based on the production process requirements； 2. The theoretical cooling capacity is increased by a certain coefficient to determine the actual cooling capacity (a coefficient of 10% can be considered) ； 3. Determine the operating conditions of the ice machine ； 4. Determine the type of ice machine: piston-type or screw-type, and initially select the cooling capacity per unit machine ； 5. Determine the number of ice machines and select the appropriate model; consider having backup units as well as ensuring compatibility with the existing power supply capacity ； 6. Assess the availability of supporting infrastructure for the project, and verify whether the selected options are reasonable ； The amount of gaseous ammonia processed by the chiller must be determined using the ammonia property table; this amount is not considered a nominal parameter for the chiller. The conversion factor between KW and Kal is 860.
