Description
System chemistry deals with chemical reactions between refrigerants, lubricants, and construction materials of various system components (e.g., compressor, heat transfer coils, connecting tubing, expansion device). Higher temperatures or contaminants such as air, moisture, and unwashed process chemicals complicate chemical interactions between components. Phase changes occur in the refrigeration cycle; in particular, the temperature extremes from the highest discharge line temperature to the lowest evaporating temperature are of importance to the end user. This chapter covers the chemical aspects of refrigerants and lubricants, and their effects on materials compatibility. Detailed information on halocarbon and ammonia refrigerants is provided in Chapters 1 and 2, respectively. Contaminant control is discussed in Chapter 7, and lubricants in Chapter 12.More information on various refrigerants can be found in Chapters29 and 30 of the 2013 ASHRAE Handbook–Fundamentals.
