deshidration
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.
When you plot a system on a mollier diagram it the point between the pressure drop and the bottom of the compression line, measured in BTU/LB. Also known as the Net Refrigeration Effect.
The net refrigeration effect in a refrigeration cycle is the amount of heat absorbed from the refrigerated space by the refrigerant gas as it evaporates, minus the amount of work done on the refrigerant gas during compression. It represents the actual amount of cooling provided by the refrigeration system.
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.
The cold temperature retards the rate at which the bacteria reproduce.
Freezer Burn is the effect of poor sealing and/or storage of foods in a Refrigeration unit.
The compressor in a refrigeration cycle is responsible for increasing the pressure and temperature of the refrigerant gas. This high-pressure, high-temperature gas is then condensed into a liquid, releasing heat in the process. This helps to maintain the cooling effect needed for the refrigeration system to operate efficiently.
The Carnot cycle is an idealized thermodynamic cycle that describes a perfect heat engine. In the Refrigeration system we need cooling effect.so it has to operate in opposite nature to produce the cooling effect. So we run the catnot cycle reversly in the refrigeration system. So we call the Refrigeration cycle called as REVERSED CARNOT CYCLE.
FLASH GAS - Instantaneous evaporation of some liquid refrigerant at the metering device due to pressure drop which cools the remaining liquid refrigerant to desired evaporation temperature.This flash gas cannot absorb any heat having a negative effect on the net refrigeration cycle
Tonne of refrigeration(TR) is the practical unit of refrigeration effect.Tonne of refrigeration(TR) is defined
Refrigeration was created in 1859
