One of the very first steps when it comes to diagnosing a home air conditioner, refrigerator, a vehicle’s air conditioner, or a commercial cooler is understanding the temperature and the current pressure that the system is operating at. Having these facts along with the saturation point, the subcool, and the superheat numbers for the refrigerant you are … Read more
HFCs, or HydroFluroCarbons, are a commonly used refrigerant classification used across the globe. Some of the most common HFC refrigerants that you may have heard of are R-134a, R-404A, R-410A, R-125, and R-32. These refrigerants are used in a variety of applications from automotive, to home air conditioners, all the way to industrial refrigeration. In … Read more
Well folks one of the big dogs in the refrigerated transport market, Carrier Transicold, has begun offering R-452A as an alternative refrigerant for their trucks here in America. Most everyone already saw this coming due to their competition, Thermo King, had already begun switching their trucks over to 452A as well. For those of you … Read more
There has been a big push over the past couple years to replace R-404A and other HFC refrigerants with alternatives. The push comes from HFCs having a larger Global Warming Potential, or GWP. GWP is compared against Carbon Dioxide which has a GWP of 1. R-404A has a GWP of 3,943. Obviously, there is quite the difference … Read more
I was reading an article earlier this week that detailed how ThermoKing, a global transport refrigerant manufacturer, was looking for an alternative to the HFC R-404A. The reasoning is the same as for the other HFCs 410A and 134a. It been known for a while that the HFCs have a very high global warming potential … Read more
