Bimetal
Two metals of different coefficients of expansion welded together so that the piece will bend in one direction when heated, and in the other when cooled, and can be used to open or close electrical circuits, as in thermostats.
Bimetal bits
Bi-metal bits are titanium-nitride-coated bits with an extremely long life. They are can be used on tough substrates like stainless or cast iron as well as on wood and plastic.
Bimetallic thermometer
Thermometer which uses the expansion of a liquid in a graduated glass tube with a reservoir bulb at one end or by a bimetallic strip that moves an indicator on a scale as the two metals expand at different rates when exposed to heat. Commonly used for the measurement of outdoor temperatures.
Bin method
A method of predicting heating and/or cooling loads using instantaneous load calculation at different outdoor dry-bulb temperatures, and multiplying the result by the number of hours of occurrence of each temperature.
Binary cycle
Combination of two power plant turbine cycles utilizing two different working fluids for power production. The waste heat from the first turbine cycle provides the heat energy for the operation of the second turbine, thus providing higher overall system efficiencies.
