R-22 to NU-22B (R-422B) Comparison Information

The results of the tests are as follows;

In test “A” the test conditions were set at 80 deg. DB entering air, with 67 deg. WB, and a condenser ambient of 95 deg. In the cooling mode we see that R-422B has 5% less EER than R-22 and operates with 5% less compres-sor amp draw. We also see that the compres-sor operates at 6% less dome temperature with R-422B, which means the compressor runs slightly cooler than with R-22.

In test “B” the test conditions were set at 80 deg. DB entering air, with 67 deg. WB, and a condenser ambient of 82 deg. In the cool-ing mode we see that R-422B has 11% less capacity, 2% less compressor amp draw, and a 10% lower discharge gas temperature than R-22. In this condition, we see that there is a slight drop in capacity but the compressor is running slightly lower in amp draw and is run-ning cooler.

In test “C” the test conditions were set at 80 deg. DB entering air, with 57 deg. WB, and a condenser ambient of 82 deg. This is con-sidered a “Dry Coil” test due to the low WB temperature. In the cooling mode we see that R-422B has 7% less capacity, 6% less EER, and 3% less compressor amp draw than R-22. We also saw 15% less discharge gas temperature than R-22.

In test “D” the same conditions were used as in test “C” for SEER testing. The end result showed that R-422B had a 1.1 less SEER than R-22 with 1% less compressor amp draw.

The next two tests were performed with the equipment in the heat pump mode. For “Defrost Heating” test, the indoor temperature conditions were set at 70 deg. DB, 60 deg. WB and the outdoor conditions were set at 35 deg. DB, and 33 deg. WB. In these conditions R-422B has a 2% lower discharge air temperature.

For “Standard Heating Rating” test, the indoor temperature conditions were set at 70 deg. DB, 60 deg. WB and the outdoor condi-tions were set at 47 deg DB and 43 deg. WB. In these conditions we see that R-422B produced 10% less heating capacity and has a 7% less COP that R-22. The results also showed that R-422B has a 3% lower discharge air temperature and drew 4% less compressor amps than R-22.

Prior to making our summary on the test information provided, we would like to mention again that ICOR did not have any input on the ARI Test Standard, the testing equipment, or test results.

In summary ICOR feels this test shows that R-422B is a proven R-22 replacement refrigerant with similar operating characteristics. If you examine the information provided in test “A”, this is a perfect example of an actual field application set up in laboratory conditions. With a 95 deg. ambient you can see that R-422B only looses 5% efficiency. This loss would typically not be noticed by the equipment owner. This loss could actually be an advantage in some comfort cooling applications, by allowing the equipment to run slightly longer which would remove more humidity from the space. We all know that less humidity on a hot summer day is a good thing. You will also notice that the compressor amp draw was slightly lower which equates to less work on the compressor.

Since this test completion, scores of R-22 equipment in a variety of applications has been retrofitted to NU-22B. We have found during these retrofits that by modifying the metering device to an adjustable TXV, we can get even closer to R-22 performance.Sporlan and Danfoss have TXV retrofit kits available. In some cases, simply modifying the refrigerant charge can improve equipment performance.

ICOR has actual field conversion data available upon request. This data provides positive proof that R-422B is a viable replacement refrigerant for R-22.

David L. Callender CMTechnical Support SupervisorICOR International, Inc.

R-422B is a blended HFC refrigerant that is comprised of R-125, R-134a, and R-600a with an A1 (non toxic, non flammable) ASHRAE safety designation. It is also on the EPA SNAP List. NU-22B (R-422B) is manufactured by ICOR International, Inc. This information is being provided to contractors, wholesalers and equipment owners that are involved, or will be involved in the phase out of HCFC 22. We are aware that there are a variety of R-22 retrofit refrigerants available on the market, and they all have their advantages and disadvantages. This particular document is focused on comparing R-22 to NU-22B (R-422B) refrigerant after a retrofit has been performed. The comparison data in this test has been provided to ICOR International, Inc. by Intertek, a third party, independent testing labora-tory in Columbus, Oh. The testing was completed on 1/11/2006. There were six different tests performed under different conditions in the cooling and heat pump mode. All tests were performed to ARI Standard 210/240-2005. The equipment used for testing was a York 13 SEER 3 ton heat pump designed to operate with R-22. It is important to note that the equipment was not modified to operate with a different refrigerant.

REMEMBERWHEN CONVERTING OR RETROFITTING

can be detected with any standard form of leak detec-tion designed to detect HFC refrigerants.

6) EVACUATE SYSTEM: To remove non-condensables and moisture in the sys-tem, a minimum 500 micron vacuum must beachieved.

7) CHARGE SYSTEM:Remove LIQUID ONLY from One Shot®(C) cylinder. When initially charging system, One Shot®(C) can be addeddirectly into the receiver tank or high-pressure side of the system with compressor off. Charge ratios for One Shot®(C) may vary depending on system design and application. The initial charge of One Shot®(C) should be 95% of the original Existing Refrigerant charge.

8) RUN SYSTEM:Check pressures, subcooling, and superheat tempera-tures. Use One Shot®(C) P/T chart on reverse side. If addi-tional One Shot®(C) needs to be added, do so in 5% incre-ments and DO NOT exceed 115% of the original chargeof existing refrigerant. If system performance is inadequate, call ICOR for support at 866-433-8324.

9) PROPERLY LABEL SYSTEM: Avoid mixing refrigerants by properly labeling your sys-tem. For One Shot®(C) system ID labels, call the ICOR support hotline at 800-497-6805.

10) POST CONVERSION LEAK CHECK:After operation of system begins, do a thorough system leak check.

11) RECORD SYSTEM POST CONVERSION DATA:

Monitor and evaluate system performance and recorddata. This information can be compared to your pre-conversion data for a full conversion evaluation andcan be used if further technical support is required.

Change from CFC and HCFC to HFC refrigerants maycause a retraction in the o-rings and elastomers. Besure to repair or replace after recovery of the origi-nal refrigerant. Failure to address this at this timemay cause unnecessary loss of refrigerant.

ICOR recommends verification of the meteringdevice sizing with the distributor or manufacturer ofthe device.

1) RECORD SYSTEM PRE-CONVERSION DATA:

Prior to converting, the system should be monitoredand all system and component operating conditionsrecorded for future reference. (SEE FORM ON REVERSE SIDE)

2) RECOVER THE REFRIGERANT100% of the refrigerant must be recovered from system in accordance with all EPA guidelines.*Recording the weight of the refrigerant you recover will assist you in determining the amount of One Shot®(C) necessary for the conversion.

3) PERFORM OIL ANALYSIS:Check system oil for acidity, water and solids (metalshavings). If detected perform a complete system oil change using the OEM specified type and amountof oil.

4) INSTALL NEW FILTER DRIER AND OIL FILTER:

The oil analysis will tell you what type of filter drier you need to use. Systems with coalescent oil separators and/or compressor oil filters need to bechanged, too.

5) LEAK CHECK SYSTEM: Pressure test system with dry nitrogen. DO NOTexceed the equipment’s design pressure. One Shot®(C)

LEADING THE INDUSTRY

IN REPLACEMENT REFRIGERANTS

DID YOU…..?

Verify your low pressure control, evaporator or crankcase pressure regulator to the correspon- ding P/T relationship.

Confirm the fan cycling setpoints.

Unless the service conditions indicate contamination,oil change is not required and standard filter driers canbe used. Remember oil loss can occur during the recov-ery process. Check oil level after system has stabilized.Adjust if necessary.

If leaks occur, you may recharge (top-off) withouteffecting system performance.

As with other replacements, systems directly con-verted from CFC’s and HCFH’s to HFC’s may experience shrinkage of o-rings or gaskets, which could contribute to leakage.

Label the system.

Verify the metering device sizing.

Use of One Shot®(C) in R-502, R-422A, R-408A, R-404A, R-402A, R-402B and R-507A conversions may not require an expansion valve replacement.As with R-404A and R-507A, the use of One Shot®(C)in R-22 retrofits will have a minimum requirementof an element change, but may require a valve replacement.
