The purpose of this article is to not only demonstrate the proper use of the pressure-temperature relationship, but to also illustrate how service technicians can use the P-T chart to thoroughly analyze a refrigeration or air conditioning system.
The AB-100CS Acid-Buster™ Injection Kit is designed to bond with acids without forming chemical byproducts and prevents acid build-up in air conditioning and refrigeration systems. Use of the injector requires only one connection to add acid scavenging solution into the system.

Now, more than ever, the industry has been looking for alternatives to R-22 to keep the huge existing base of R-22 equipment up and running. More reclamation has been one option. But at the same time, attention is being paid to a large number of HFC refrigerants that can be retrofitted into R-22 equipment.
Because no one HFC refrigerant can be retrofitted efficiently into the entire range of R-22 equipment, a wide and sometimes changing variety of HFCs have entered the market. The NEWS contacted a number of refrigerant manufacturers asking them to discuss some of their most popular HFCs for R-22 retrofits.
Two recent refrigerant developments focus on CO2 and HFOs. One relates to CO2 in refrigeration; the other is an announcement of an HFO in air conditioning.
A ruling to the pending regional standards lawsuit may be less than a month away. American Public Gas Association (APGA) executive vice president Dave Schryver confirmed that the lawsuit, APGA v. U.S. Department of Energy (DOE), has entered mediation and that an agreement between the two parties could occur very soon.
