The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.
Inversely to superheating, subcooling, or the amount of heat withdrawn from the liquid refrigerant on the subcooling process, manifests itself as an increase on the refrigeration capacity of the system. This means that any extra heat removal after the condensation (subcooling) allows a higher ratio of heat absorption on further stages of the ...
The inclusion of a refrigerant receiver is a common, cheap and simple way of decreasing the gas ratio in the liquid line. The incorporation of a subcooling stage after the receiver reduces even more the chances to observe flash gas. [5] This subcooling may be done in a reserved portion of the main condenser, or separately with a heat exchanger ...
Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...
Supercooled water, still in liquid state Start of solidification as a result of leaving the state of rest. Supercooling, [1] also known as undercooling, [2] [3] is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid.

In steam locomotive use, by far the most common form of superheater is the fire-tube type. That takes the saturated steam supplied in the dry pipe into a superheater header mounted against the tube sheet in the smokebox. The steam is then passed through a number of superheater elements, which are long pipes placed inside the larger diameter ...
