Refrigeration Cycle and Components
The cooling cycle can be defined as the temperature changes caused by the subsequent emitting of a heat-absorbing refrigerant.
The fluid used in the refrigeration cycle is called a refrigerant or refrigerant. The saturated vapor exiting the evaporator is absorbed by the compressor and compressed to the condensation pressure. In the meantime, the temperature increases as well. The refrigerant in the case of superheated steam enters the condenser and the heat taken from the evaporator and the sum of the work given during the compression process transfers the bleaching heat to the external environment. saturated liquid and enters the expansion valve. As a result of the friction increase due to the narrowing of the cross-section, the liquid-vapor mixture, most of which is liquid, evaporates by taking heat from the external environment and compressor.Reaches the entrance.
The steam compression refrigeration cycle has four main elements;
Evaporator evaporates the refrigerant increases the condensing pressure in the compressor and serves to increase the pressure of the gas in the cooling system. Semi-Hermetic Piston Compressor, Semi-Hermetic Screw Compressor, Hermetic Piston Compressor, Hermetic Scroll Compressor.
The refrigerant condenses in the condenser by throwing heat to the external environment and thus in the high pressure gas condenser coming from the compressor, at a constant pressure, first saturated steam, then saturated liquid is made.
- Expansion Valve:
The pressure of the condensed fluid is reduced to the evaporation pressure in the expansion valve and sent back to the refrigerant. For this process, the cross section is narrowed and the pressure is reduced by the effect of friction.
Helps the evaporation of the refrigerant and cooling the environment by attracting the heat in the desired environment to be cooled.
