ASHRAE F31-2009 (SI)

In many refrigeration applications, heat is transferred to a secondary coolant, which can be any liquid cooled by the refrigerant and used to transfer heat without changing state. These liquids are also known as heat transfer fluids, brines, or secondary refrigerants.

Other ASHRAE Handbook volumes describe various applications for secondary coolants. In the 2006 ASHRAE HandbookRefrigeration, refrigeration systems are discussed in Chapter 4, their uses in food processing in Chapters 14 to 29, and ice rinks in Chapter 35. In the 2007 ASHRAE HandbookHVAC Applications, solar energy use is discussed in Chapter 33, thermal storage in Chapter 34, and snow melting and freeze protection in Chapter 50.

This chapter describes physical properties of several secondary coolants and provides information on their use. Additional, less widely used secondary coolants such as ethyl alcohol or potassium formate are not included in this chapter, but their physical properties are summarized in Melinder (2007). The chapter also includes information on corrosion protection. Additional information on corrosion inhibition can be found in Chapter 48 of the 2007 ASHRAE HandbookHVAC Applications and Chapter 4 of the 2006 ASHRAE HandbookRefrigeration.
