Patterns of Refrigerant Use Resulting From Regulations Designed to Protect the Environment

Abstract

The HVAC&R industry is changing rapidly. This is response to the environmental challenges of ozone depletion and global warming. The contractor working in this industry faces tough competition and increasing technical difficulties. These difficulties can be turned into a competitive advantage if the contractor understands the source of the difficulties. This paper explores some of the industry wide problems and solutions. The new refrigerants are many and are covered by venting, recycling and reclamation rules. They are very stable refrigerants and are generally used with ester lubricants. Understanding some of these issues will allow contractors to take advantage of the benefits brought about by some of these technological changes.
