Enter the gas in the pipe, the compressor/condenser section, and the evaporator section into the calculator to determine the Refrigerant Charge.
Refrigerant Charge Formula
The following formula is used to calculate the Refrigerant Charge.
Cr = GP + CC + E
- Where Cr is the Refrigerant Charge
- GP is the gas in the pipe
- CC is the compressor/condenser section
- E is the evaporator section
How to Calculate Refrigerant Charge?
The following example problems outline how to calculate the Refrigerant Charge.
Example Problem #1
- First, determine the gas in the pipe. In this example, the gas in the pipe is given as 15 .
- Next, determine the compressor/condenser section. For this problem, the compressor/condenser section is given as 14 .
- Next, determine the evaporator section. In this case, the evaporator section is found to be 13.
- Finally, calculate the Refrigerant Charge using the formula above:
Cr = GP + CC + E
Inserting the values from above yields:
Cr = 15 + 14 + 13 = 42
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are as follows:
gas in the pipe = 6
compressor/condenser section = 7
evaporator section = 8
Entering these given values and solving gives:
Cr = 6 + 7 + 8 = 21
