Goodman Piston Chart 2022 (2024)

FAQs

What size piston is used for R22? ›

An example would be 5800A12345. 58 is the factory, 00 represents the year 2000 and A means it was manufactured in January. Goodman serial numbers are 10 digit numerical where the month and year are encoded in the first 4 digits. The year is the first 2 and the month the second 2.

LOOK AT THE MODEL NUMBER OF THE UNIT ,IN THE MODEL NUMBER THERE WILL BE A NUMBER THAT WILL BE ONE OF THE FOLLOWING,12,18,24,30,36,42,48,54,60 THESE NUMBERS REPRESENT FROM A 1 TON TO A 5 TON SYSTEM. 12 1 TON ,18 TON AND A HALF,24 TWO TONS ,30 TWO AND A HALF TONS,36 THREE TON,42 THREE AND A HALF TON.

Ultimately, the bore should be measured for the best possible results. After the diameter is known, then you can pick which size piston will work best in your cylinder. Remember to maintain about a 0.05mm (0.002”) piston to cylinder clearance, depending on application.

If a service technician unwittingly mixes RS-44b with R22, there will be no harm to the system or its components. However, in the U.S., the Environmental Protection Agency (EPA) strictly prohibits deliberately mixing refrigerants and will assess fines and penalties to address the violation.

An air conditioner's model number is a string of numbers and letters. Within the string, you should see an even, two-digit number. Add three zeroes to the number and you have the BTU rating. Divide the two-digit number by 12, and you have the tonnage.

A good general rule to start with for finding the right size AC unit is to have 20 BTU for every square foot of house. So a 1,000 square foot home would need a 20,000 BTU air conditioner. Remember, you can then convert this to tons. 12,000 BTUs are equivalent to one ton.

How To Find The SEER Rating. Head over to your cooling system and look for a yellow and black “energyguide” sticker, which can usually be located on the side of the condenser. If this sticker is still in tact, it will tell you the Seasonal Energy Efficiency Ratio in large numbers.

Systems with receivers may experience some fractionation of the refrigerant in the receiver and have somewhat lower capacity. 8. R-407C exhibits higher pressures than R-22 at normal condensing temperatures.

Using R-22 in an air conditioning application, gauge suction pressure is at 70 PSI and gauge discharge pressure is at 250 PSI. First you need to convert these gauge pressures to PSIA. 265psia Do the math and you will find an answer of 3.1 to 1 or 3:1 (close enough).

Is R-22 and 422 the same? ›

Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting hydrofluorocarbon (HFC) replacement for R-22.
