what are the six states of a refrigerant in a refrigeration cycle
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.
This type of detector is of no importance for electric powered refrigeration systems, as ammonia is not used in them. This type of detector is a safety device for natural gas and propane powered refrigeration systems as ammonia is the coolant in such systems and a leak of ammonia vapor is toxic.
In non-cyclic refrigeration, cooling is accomplished by melting ice or by subliming dry ice (frozen carbon dioxide). These methods are used for small-scale refrigeration such as in laboratories and workshops, or in portable coolers. UET TAXILA Mechanical pirates
First step in refrigeration is evaporation. The next step is compression, which raises the pressure of the refrigerant vapor. Condensing is the third step and is where the heat transfer takes place. Expansion is the fourth step and is where the condenser cools the refrigerant even more, to a level below the condensing temperature.

It is a refrigeration unit based on Vapour Absorption Refrigeration Cycle (typically refrigerants used are Water or Ammonia).
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.
In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.

The Bell-Coleman Cycle is also known as the Air-Standard Refrigeration Cycle or Reverse Brayton Cycle. This 4-process refrigeration cycle involves isentropic compression, followed by isobarric heat rejection, then isentropic expansion (usually by a turboexpander), and finally isobarric heat intake.This cycle is commonly used in jet aircraft, using engine bleed air for compression and venting to the atmosphere. It is also commonly used in commercial air liquification plants.

A package unit contains all elements of the refrigeration cycle in one system. The 4 major components include: A compressor, condenser, metering device, and a evaporator. All elements are needed to complete the cycle of refrigeration. As for a split unit, All elements of the refrigeration cycle are used, however the condenser is located outside of the facility, while the evaporator is located inside of the facility. To better understand the difference in question, you must understand the job of each component in the refrigeration cycle. For example, a condenser is normally used to reject heat or cold air from a building, while a evaporator normally supplies heat or cold air to the building.

To return oil to the compressor.
Indirect and direct refrigeration systems are typically used on LPG carriers for cooling different cargos. Indirect systems cool the cargo by a refrigerant without being compressed. In the direct refrigeration cycle the cargo is compressed, condensed and returned to the tanks. The safer method is indirect refrigeration because the cargo never mixes with the refrigerant.
