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
To calculate a refrigerant charge, add together the gas charge in the pipe, compressor section, and 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
