Because we can't make cold, we can only remove heat. So refridgeration is always about moving heat away from one spot and dumping it somewhere else.
the importance of refrigeration because when the heat is exesrted from lower temperature to higher temperture
The function of the evaporator is to cool the air by absorbing heat into the refrigeration system.
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
No they are not. In fact a heat pump contains within it a heat exchanger/coil. A heat pump is reverse refrigeration. A heat exchange, exchanges heart from a heat source to a conditioned space (the area you want heated). While a heat pump uses a heat exchanger to supply heat to the conditioned space. Reverse refrigeration uses the air conditioner in reverse(you know how heat comes if the back of yhe air conditioner, well when it's in reverse that heat is used to heat a home in winter months.
A Ton is the measurement of the amount of heat required to melt one ton of ice. It is also 12,000 BTU (British Thermal Unit) So the Ton is a measurement of the amount of heat that the refrigeration system can remove.
Compression refrigeration uses a compressor to increase the pressure of the working fluid after the evaporator. Absorbtion refrigeration uses heat (usually waste heat from another process) to raise the pressure.
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.

The reverse of a heat engine operating is a refrigeration system operating. In a heat engine, heat is converted into work, while in a refrigeration system, work is used to transfer heat from a lower temperature to a higher temperature.
A heat pump is similar to a refrigeration system in that it uses the refrigeration cycle to transfer heat from one location to another. Both systems utilize a compressor, condenser, expansion valve, and evaporator to move heat from a lower temperature area to a higher temperature area. The main difference is that a heat pump can operate in reverse to provide both heating and cooling, while a refrigeration system is typically designed only for cooling purposes.
A heat pump and a refrigeration cycle both involve the transfer of heat, but they have different purposes and operate in slightly different ways. A heat pump is a device that can both heat and cool a space by transferring heat from one location to another. It can extract heat from the air, ground, or water and transfer it inside a building to provide warmth, or it can remove heat from inside a building and release it outside to cool the space. On the other hand, a refrigeration cycle is typically used for cooling purposes only. It involves the compression, condensation, expansion, and evaporation of a refrigerant to remove heat from a space and maintain a lower temperature. In summary, while both a heat pump and a refrigeration cycle involve heat transfer, a heat pump can both heat and cool a space, while a refrigeration cycle is primarily used for cooling.
Refrigeration is a process in which work is done to move heat. It was a closed-cycle that could operate continuously, as he described in his patent.
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 two types of refrigeration are vapor compression refrigeration and absorption refrigeration. Vapor compression refrigeration is the most common type and is used in most household refrigerators and air conditioning systems. Absorption refrigeration, on the other hand, uses heat to generate a refrigerant vapor instead of a mechanical compressor.
Rejects the heat from the compressor and cold coil (evaporator).
