Shown on a Live AC Unit! AC ... How To Refill R22 AC With Subcooling Method. Word of Advice TV•330K ...Subcooling is the amount of liquid held back in the condenser. This allows the liquid to give up more heat, below saturated pressure- temperature. For every one degree of subcooling at the same condensing+ pressure, capacity will increase .5 percent. See the chart that I developed for HVACPro app. Target subcooling at 80°F = 11.8°F. Target subcooling at 90°F = 11.9°F. Target subcooling at 100°F = 11.9°F. Target subcooling at 100°F = 12.1°F. You can see that this range (from 11.7°F to 12.1°F) is very tight; only 0.4°F difference between very low 70°F outdoor temperature and very high 110°F outdoor temperature.

Up to 10% lower capacity. Lubricant Recommendation: Compatible with mineral and alkylbenzene oil and if oil return becomes a concern, addition of polyolester lubricant in 5% increments could help resolve the issue.
