tCold
Tcold is a term used in thermodynamics and cooling technology to designate the temperature at the cold side of a thermal system. It is most commonly encountered in analyses of refrigeration cycles, cryogenic cooling, and liquid-plant operations. Tcold is usually defined as the lowest temperature that the system can maintain at its cold reservoir or cold stage, and it is often contrasted with Thot, the corresponding hot-side temperature. The difference ΔT = Thot − Tcold is a key parameter in assessing performance, along with the coefficient of performance (COP), efficiency, and refrigerant properties.
Measurement and control: Tcold is measured with sensors such as thermocouples or resistance temperature detectors placed
Technologies: The Tcold value can be achieved by several cooling cycles. In domestic and industrial refrigeration,
Notes: Tcold is a variable name common in system diagrams and thermal models; it is sometimes written
