Oz-Chill 22a (R290) is a, hydrocarbon based refrigerant blended from environmentally safe hydrocarbons and is a direct replacement and retrofit refrigerant option for replacing R22. These refrigerants are generally found in commercial air conditioning and refrigeration systems. 22a operates at much lower head pressures and offers improved cooling properties and performance compared to R22.
1. Lower Running Cost: Once converted to 22a, the amp draws and running costs will decrease. Savings of up to 30% can be achieved!
2. Operation: Oz-Chill 22a possesses similar volumetric refrigerating effects to R22. 22a will operate at lower head pressures and offers improved cooling properties and performance versus R22. 22a can be used effectively in refrigeration systems without major “retrofitting”.
3. Compatibility: Oz-Chill 22a is compatible with most common refrigerant materials including R22 and R22 metal components, mineral and synthetic(Ester and PAG) lubricants, seals, gaskets, hoses, compressors, and o-rings.
4. Less Refrigerant: Oz-Chill 22a only needs approximately 30%-40% charge, compared to the original R22 charge amount. This is due to the efficiency properties of the blend. Therefore reducing amount of refrigerant needed and cost of job.
5. Environment: Oz-Chill 22a is a natural, organic refrigerant, non-ozone depleting. 22a is in full compliance with the UN Montreal Protocol.
6. Safety: Oz-Chill 22a does not become caustic when contaminated with moisture or oxygen. Non-toxic, non-carcinogen, autoignition temperature above 467.2 C. No long term health risks have been attributed to Oz-Chill 22a refrigerant.
Refrigerant Installation/Charging Guide for 22a
A) PRE-CHARGE INSTALLATION
1 ) Inspect the system and determine if the system is operating correctly. Any repairs should be carried out prior to converting A/C system to OZ-CHILL 22a.
2 ) Check the system for refrigerant leaks using appropriate leak detection procedures and tools.
3 ) Leaks in metal lines, condensers, evaporators, fittings, can be repaired effectively by installing OZ-CHILL Pro Seal Plus, Seal Treatment.
4 ) Install gauge set and check and record suction and discharge pressures, if they are not correct recharge system with R22 until correct value is achieved. If pressure is low determine if there are any leaks in system.
5 ) Use a duct or Infrared thermometer to capture and record the center vent temperature. This will supply the installer a temperature reference, allowing the installer to compare before and after temperature readings.
6 ) Record temperature on suction and discharge pipes as reference.
7 ) Determine the type of refrigerant currently in the a/c system. The OEM tag indicates the type and amount of refrigerant in the system (note the amount may change due to extended suction and discharge pipes)
8 ) Evacuate the refrigerant in the system prior to installing OZ-CHILL 22a refrigerant. Recover all existing refrigerants into a suitable approved container and mark appropriately, as REGULATIONS PROHIBIT THE VENTING OF REFRIGERANTS INTO THE ATMOSPHERE. Although OZ-CHILL 22a is compatible with most existing refrigerants and oils, DO NOT MIX REFRIGERANTS. Mixing refrigerants will not offer the maximum performance available from OZ-CHILL 22a.
9 ) Weigh the refrigerant recovered as a reference for weight of OZ-CHILL 22a to be installed. This must be determined before initiating a OZ-CHILL 22a recharge
10 ) Determine the approximate amount of OZ-CHILL 22a Refrigerant required in the system with the use of the OEM refrigerant information and the weight of refrigerant recovered, and use the OZ-CHILL 22a Conversion Chart to estimate OZ-CHILL 22a refrigerant charge size to be installed..
11 ) OZ-CHILL 22a Refrigerant is installed as a liquid through the low side service port.
12 ) PULL A SYSTEM VACUUM, make sure vacuum of about 30psi is obtained to ensure all traces of R22 are removed. The cleaner the system the better the results obtained when converting to OZ-CHILL 22a.
B) CYLINDER CHARGING PROCEDURE
Follow all OZ-CHILL 22a safety precautions before initiating charging process.
1 ) Calculate approximate charge size of OZ-CHILL 22a required. This will be approximately 33% – 35% of R22 charge by weight. (e.g if 2 Kg of R22 removed we estimate we will need about 0.67 Kg of OZ-CHILL 22a).
2 ) Properly connect Manifold Gauge Set to OZ-CHILL 22a cylinder.
3 ) Locate Low Side Service Port and connect low side charging hose.
4 ) Locate High Side Service Port and connect high side charging hose.
5 ) Place refrigerant cylinder on electronic charging scale and set weight to 0.
6 ) Slowly open liquid charging valve allowing refrigerant to enter system slowly.
7 ) Continue with charging process taking care to ensure we do not reach calculated weight of OZ-CHILL 22 required. When we reach 10 psi below suction pressure recorded with R22 slowly charge system checking temperature of suction and discharge pipes. When charge is close to correct working pressure we will feel a change in suction and discharge temperatures. At this point we need to check air outlet vent temperature to see when we have achieved similar or better cooling.
8 ) At this point stop charging system, if we have achieved similar or better cooling at a lower pressure this will increase the saving achieved. DO NOT OVERCHARGE! THERE IS NO POINT IN OVERCHARGING THIS WILL NOT IMPROVE COOLING, IT WILL ONLY REDUCE COOLING AND THEREFORE USE MORE POWER.
9 ) After OZ-CHILL 22a charging procedure is completed, turn cylinder valve clockwise until valve is fully closed.
10 ) Remove charging hoses from low and high side service ports
11 ) Record weight of OZ-CHILL 22a used to charge system.
12 ) Store unused OZ-CHILL 22a refrigerant in a well ventilated place away from open flames.
13) Apply OZ-CHILL refrigerant identification tags in a highly visible area near charging port.
