- T1
- Measuring point for compressor acceptance test. Temperature at
the compressor inlet flange. (010)
- T3
- Measuring point for compressor acceptance test. Temperature
before an orifice or nozzle, downstream of compressor discharge.
(099)
- Temperature
- Is the property of a substance that gauges the potential or
driving force for the flow of heat. (030)
- Temperature absolute
- The temperature of a body referred to the absolute zero, at
which point the volume of an ideal gas theoretically becomes zero.
(Fahrenheit scale is minus 459.67°F / Celsius scale is minus
273.15°C). (010)
- Temperature
discharge
- Is the temperature existing at the discharge port of the
compressor. (030)
- Temperature inlet
- Is the temperature at the inlet flange of the compressor.
(030)
- Temperature intake
- The toal temperature at the intake flange of the compressor.
(060)
- Temperature rise
ratio
- Is the ratio of the computed isentropic temperature rise to
the measured total temperature rise during compression.
(060)
- Temperature static
- The actual temperature of a moving gas stream. It is the
temperature indicated by a thermometer moving in the stream with
the same velocity as the stream. (060)
- Temperature total
- The temperature which would be measured at the stagnation
point if a gas stream were stopped, with adiabatic compression
from the flow condition to the stagnation pressure.
(060)
- Theoretical power
- The power required to compress a gas isothermally through a
specified range of pressures. (556)
- Thermal compressor
- is an ejector used to compress waste or exhaust steam or any
other gas through a moderate range of compression above
atmospheric pressure. (755)
- Thermal mass
- Material that stores energy, although mass will also retain
coolness. The thermal storage capacity of a material is a measure
of the material's ability to absorb and store heat.
(081)
- Thermodynamics
first law of
- The amount of work done on or by a system is equal to the
amount of energy transferred to or from the
system.(010)
- Thermodynamics
second law of
- Heat cannot, of itself, pass from a colder to a hotter
body.(010)
- Thrust balancing
device
- The part of a rotating element that counteracts any inherent
thrust developed by the impellers. (060)
- Tilting pad
- A type of journal bearing in centrifugal air compressors.
(020)
- Torr
- A unit of pressure used with vacuum pumps, equal to 1mm of
mercury and 133.32 Pascal's. (188)
- Total package input
power
- The total electrical power input to a compressor, including
drive motor, cooling fan, motors, controls, etc. (556)
- Torque
- Torsional moment or couple. It usually refers to the driving
couple of a machine or motor. (020)
- Trunk compressor
- A compressor belonging to the group of displacement
reciprocating compressors. (010)
- Trunnion
- A device for mounting cylinders. (010)
- Tugger
- An air operated device for hoisting or pulling. Similar to a
slusher or winch (099)
- Tundish
- A receptacle, open to atmosphere, that is used to used to
collect condensate. For example, two or three drain pipes from
various filters may be discharging into a funnel. In this case the
funnel is a tundish. (188)
- Two stage compressor
- Machines in which air or gas is compressed from initial
pressure to an intermediate pressure in one or more cylinders or
casings. (060)
- Two step control
- Load/unload control system that tries to maximizes compressor
efficiency by matching air delivery and air demand. Compressor is
operated at full load or idle (200)
- TXV valve
- A thermal expansion valve. (020)
