Portable Chiller Systems Glossary: B
Boiling Point is the temperature at which a liquid (here, Heat Transfer Fluid and Refrigerant) begins to change from a liquid to a gaseous state, or boils. It is necessary to choose fluids, and design and program Chiller Systems, such that the fluids in the sytem do not reach the boiling point.
The British thermal unit (BTU) is a traditional unit of work equal to about 1055 joules. It represents the amount of work needed to raise the temperature of one pound of water by one degree Fahrenheit. In the Chiller Industry. The BTU is often used to describe or quantify a chiller's capacity to cool/remove heat.
