IIR -- Properties of Secondary Working Fluids for Indirect Systems (Secondary Refrigerants or Coolants, Heat Transfer Fluids) PDF

This greatly expanded 2nd edition of a booklet entitled "Thermophysical Properties of Liquid Secondary Refrigerants" responds to rising use of secondary refrigerant systems used in applications ranging from solar heating at high temperatures to freezers in supermarkets. It comprises comprehensive data on a number of aqueous solutions of ethylene and propylene glycol, ethanol, glycerol, ammonia, chlorides and potassium salts. An entire chapter is devoted to: freezing point, density, specific heat, thermal conductivity, viscosity, boiling point, vapour pressure, surface tension and specific conductance. The book also deals with the selection of a suitable secondary refrigerant, technical calculations and computer treatment of data. Vital issues such as toxicity, the environmental impact and corrosion are covered.

Charts make it possible to compare commercial products and to perform comparisons of fluids with respect to energy transport, pressure drop and heat transfer. An entire chapter is devoted to carbon dioxide and another chapter deals with fine crystalline ice slurry.

Dozens of tables and charts enable readers to obtain data on 14 working fluids.
