View Full Version : Do compressors last longer....
Using R404A or high pressure gas in R134A compressors, will it cause the compressor to lose its efficiency and also decrease its life span.
From the threads i have seen many people are starting to use compressors that are not suitable for some refrigerants. So i would like to know how well this compressors hold pressures and what detrimental effects would it have on the long run. :rolleyes:

Of course compressors have shorter lifespans when you use a higher pressure gas in a compressor rated for lower pressures, but then again compressors are made to run for 20+ years for a specific gas, so even if that life-expectancy was cut in half by using a higher pressure gas, you should be fine. (I don't recall seeing any phase change units that have been running for 10+ years :p: )

well, the condensing temperatures we are working with are far lower then what most systems run at. So a r134a compressor is rated (mostly) up to 15 bar while we would run a r134a setup at 7-9 bar discharge pressure. As long as you keep the higher pressure refrigerant at 15 bar condensing pressure or lower the compressors life span isn't affected.
