3.5.1. Calculation of freezer refrigeration load
The individual items to be taken into account in a refrigeration load calculation depend on the type of freezer. It would be impossible to include all the eventualities in one sample calculation; therefore, a relatively simple one is given below for a HPF and some notes have been added to help with other freezer calculations. Load calculation I. Number of freezer
II. Fish load
An approximate figure can also be calculated by using the following values:
Using these values, the above calculation for fish refrigeration load would be:
Total refrigeration requirement with allowances:
The calculation of fish load gives refrigeration requirement to freeze the fish only. Depending on the type of freezer used, other heat loads such as fan heat, pump heat from circulating pump, heat leak through freezer insulation, heat load due to pallets, trays, trolleys, defrost procedure, air infiltration,internal lighting etc. have to be taken into account and added to this value to determine the total refrigeration requirement. |
