CHILLER UNIVERSITY |
| Now that I know the BTU's to be
removed from my process, how do I relate that to sizing a chiller to handle
it? Good question? You seem to be paying attention. I think I will let you sit at the front of the class. Now, back to your question. Chillers are generally sized in TonsR or Tons of refrigeration. A refrigeration ton is equal to 12,000 BTU's. Therefore, a 3 Ton chiller can remove 36,000 BTU's. Keep in mind, however that there are other factors that effect a chiller's performance. High ambient temperature will reduce the chiller capacity. Low fluid temperatures also reduce the capacity of the chiller. When these factors become involved, alternative refrigerants may be used. High ambient refrigerants such as R134A or R416A may be used. In low fluid temp applications a refrigerant such as R404A may be used. Each refrigerant has its own characteristics which make it better in one application and less effective in another. As this is a course dedicated to chillers, we will not spend much time explaining the refrigerants. A word that you may choose to explore on your own time, which explains more clearly the different characteristics of refrigerants is ENTHALPY.
