2-9. REMOTE CONDENSING
UNITS INFORMATION
(Continued) Refrigeration Capacities
We provide refrigeration capacity at two evaporation temperatures.
• Blast Chiller : 0°C (32°F) and –20°C (-4°F).
• Blast Freezer –20°C (-4°F) and –40°C (-40°F). Combined
units (Chiller/Freezer) are basically Blast Freezers.
The remote condensing units have to be selected in accordance with
these two data points. Refrigeration capacity of remote condensing
units have to be equal or higher than the requirement.
Example for a Blast Chiller:
Evaporation temperatures
0°C (32°F) -20°C (-4°F)
Refrigeration capacity needed 17000 W 7300 W
Remote condensing unit A 16900 W 7500 W
No Good
Remote condensing unit B 17100 W 7280 W
No Good
Remote condensing unit C 17010 W 7310 W
Both Work
Blast Chiller/Freezers start-up at high internal air temperature,
because of the hot food. The condensing unit runs at a high evapo-
ration temperature at beginning of the cycle and a low evaporation
temperature at the end of the cycle, when the food is cooled down.
Usually a single evaporation temperature is used when
specifying a condensing unit, because cold cabinets and
cold rooms run at a single temperature. But, blast chiller/
freezers require both data points, or the blast chiller/
freezer may not hold product at safe temperatures.
