A huge portion of refrigeration systems use part of the condenser for subcooling which, though very effective and simple, may be considered a diminishing factor in the nominal condensing capacity. A similar situation may be found with superheating taking place in the evaporator, thus an internal heat exchanger is a good and relatively cheap ...
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. Some receivers may incorporate an internal heat exchanger that draws heat form the subcooled liquid to superheat the gas ...
[1] [2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics . The COP usually exceeds 1, especially in heat pumps, because instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps additional heat from a heat source to ...
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
It is possible, at a given pressure, to superheat a liquid above its boiling point without it becoming gaseous. Supercooling should not be confused with freezing-point depression. Supercooling is the cooling of a liquid below its freezing point without it becoming solid.
Alcohol is used as a social lubricant, maybe more so as holiday festivities approach. But drinking carries health and other risks. Here are five tips to make it safer.
Such is the case of subcooling the liquid line by any other means that draws the heat out of the main system. For example, a heat exchanger that preheats cold water needed for another process or human use, may take heat from the liquid line, effectively subcooling it and increasing the system's capacity. [6]
