Here we present the tables of calculation and selection of chillers for the plastics industry.

Calculation and Selection of your Chiller

The selection of the chiller is obtained based on the following tables, the ideal selection is based on the closing capacity of the machine table 1, tables 2 and 3

They are complementary on the basis of kilos of product or hp Injector

Example: Based on Table 1

if you drive three injection of 150 to 200 tons, the chiller would be recommended only 15 toneladassi cool the mold, if you want to cool the mold and Oil. 20 tons

Tables for calculation and selection of injection machines Chillers

1.-On the basis of Tons Injection of the machine or force closure

Note: Cal = 3.024 K 1 ton of cooling
Example:
mold and oil cooling
A 150 ton machine 16.000
2 200 ton machines 40.000
Total k cal / hr 56.000
Tons = 56.000

Chiller capacity = 18.51

Process

Calculated based on the flow

The calculation of the heat load or capacity of the chiller is based on
Water flow in liters per hour: (enter the flow)
The desired temperature input to the process: (enter the desired temperature)
The outlet temperature of the process: (enter the outlet temperature)

Calculated based on kilograms of product:
1 .- Number of product to be chilled by the amount of time? Kilos per hour, gallons per minute or liters per minute?

2.-Temperature Input and Output of the product in degrees Fahrenheit or Celsius?

3 .- Specific heat of product

Heat load:

Air Conditioning

Calculated based on the heat load:
The selection of a chiller is based on ARI conditions and usually designed, calculated worship at 45oF and 55oF chiller output to the input of Chiller, considering these parameters the flow of water per minute per ton of cooling is 2.4 gallons per minute.

Thermal Loading: (enter the thermal load)
chiller inlet temperature: (enter the return temperature)
The outlet temperature of the process: (enter the outlet temperature)
