Prevent Refrigerant Migration
Refrigerant migration is a natural process that occurs during the off-cycle. The refrigerants have an affinity for oil and seek out the lowest-pressure areas, so it only makes sense that some refrigerant would be drawn to the compressor crankcase and may condense there. When the refrigerants condense, they saturate the oil. As a result, refrigerant […]Read more
The "Other" Pressure Switch
The chart above is from a Carrier heat pump, and it lists some common accessories. I have heard this common pressure switch (last on the list) called a low-pressure switch (because it opens on fall in pressure) and a high-pressure switch (because it's in the liquid line), but RARELY do I hear it called its […]Read more
What is the "Mid Point" of a Refrigerant Blend?
As we have mentioned in several previous articles (such as this one HERE), many blended refrigerants have glide, which simply means they boil and condense over a range of temperatures instead of just one temperature. As an example, consider refrigerant R407c. It is a zeotropic blend, which means it has enough glide to make a […]Read more
