Refrigerant-503 Low-Temperature Refrigerant

Form #: 620-79
This chapter covers the Refrigerant R-503. R-503 is an azeotropic mixture of R-23 and R-13 with improved properties for use in the medium low-temperature range (-100 to -150°F). It is normally used in reciprocating compressors as the second stage in cascade systems with R-502, R-12 or R-22 in the first stage. (620-79-Refrigerant-503)

Flammability and Explosive Hazards of R-22

Form #: 620-93
This chapter covers flammability studies with various mixtures of R-22 and air, with and without added oxygen. These mixtures can be flammable, and the possible hazards should be recognized. Some of these findings are summarized here.

Moving to Alternative Refrigerants

Form #: 620-94
To assist equipment owners in the transition to non-ozone-depleting refrigerants, EPA has undertaken a "Cooling and Refrigerating Without CFCs" initiative. As part of this initiative, EPA is publishing case histories which describe equipment retrofits and replacements actually implemented by companies around the United States.

Refrigerant Designations: Update

Form #: 620-95B
The purpose of this chapter is to provide HVAC/R service engineers and technicians with a ready source of reference, listing and explaining many of these designations.

Technology Without Fluorocarbons: What's Available

Form #: 620-99
This chapter is an overview of non-fluorocarbon alternatives. The reproduction of this material is for reference and educational purposes only. Some of the subjects covered: hydrocarbons, ammonia, carbon dioxide, and Technologies other than Vapor Compression (such as: evaporative cooling, gas expansion, absorption, adsorption, stirling cycle, and air)

Refrigerant Update for 2010 and Beyond

Form #: 650-001
What HFC refrigerant should you use to replace the original R-22 refrigerant when servicing or repairing an existing piece of equipment? This is one of the major issues facing the typical HVACR contractor today, whether the equipment in question is a selfcontained rooftop package or a field-installed split system. This document contains two specific “flow diagrams” that have been formulated to assist contractors and technicians with this vital decisionmaking process. The refrigerants suggested in these flow diagrams are typical choices that can be found in most regions of North America. It is the procedure and methodology that are of prime importance. These flow diagrams can be used with most existing installations, and pertain to both air conditioning and refrigeration applications.
