To protect the system from freezing up, the switch setting will need to be set in and around 101.6 PSI. When speaking in regards to refrigeration, the low pressure switch is usually set up to shut down the system when it reaches set point or after a pump down .Share this Tech Tip: Evaporator temperatures below 32° are common and acceptable in refrigeration; that's why there is a defrost sequence. In a heat pump running in heat mode, it's the same; freezing is a part of the process, and defrost is necessary. In comfort cooling, we can't allow the evaporator to get below 32°, or it will freeze.Argument #1: Pressure .

The mass flow rate and operating pressures of Freon™ MO99 are the closest of all the mineral oil compatible replacement products and will likely perform adequately in an existing R-22 system with a capillary tube expansion device. However, for optimal results, it is recommended to replace the capillary tube with a TXV when possible.Jul 6, 2022 ... 2. The pressure of R410A is about 1.6 times higher than that of R22 refrigerant (absolute pressure = relative pressure or gauge pressure + 1 .... R-404A began seeing usage in 1996 after the phstates that the working pressure should be around 410 psig, w R-407C is a zeotropic blend of R-32 (Difluromethane), R-125, and R-134a (Tetrafluoroethane). It is not a drop in replacement on R-22 machines. If you wish to use this product you will need to vacate all of the old R-22 out of the system. This is due to the R-22 systems using mineral oil and this HFC blend using POE oil. I originally wrote this guideline back in 2003 The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...217 PSIG Likewise, an R-410A recovery bottle with a surrounding air temperature of 75°F should have an internal pressure of 217 PSIG.
