摘要

Heat transfer fluids come in many different chemistries, from water-based to organics, depending on the application. The most important characteristics of any industrial heat transfer fluid are: 1. It removes or supplies heat quickly and efficiently. 2. It does not corrode the materials of construction. 3. It does not pose any safety hazards during operation. Most commonly, water-based solutions are used between the temperatures of -40 to 250°F (-40 to 121°C) for food and beverage, pharmaceutical and HVAC. Mineral oils and synthetic oils generally are used at higher temperatures - in the range of 300 to 750°F (149 to 399°C) - where the system pressure from using superheated water would be too high. At subzero temperatures, hydrocarbons also can be used, but there are more effective options. Glycols and brines are better suited to that range due to their low viscosities and good heat transfer properties. In fact, glycols are most commonly used as an antifreeze additive to water and found in applications such as the coolant in engine blocks and HVAC systems.
