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 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.
Evaporator is not a basic component of the compression refrigeration cycle. The basic components are compressor, condenser, expansion valve, and evaporator.
The coefficient of performance in the refrigeration cycle is important because it indicates how efficiently the refrigeration system can transfer heat. A higher coefficient of performance means the system is more efficient at cooling, which can lead to lower energy consumption and cost savings.
In the modern refrigeration cycle, the compressor plays a crucial role by compressing the refrigerant gas, increasing its temperature and pressure. This high-pressure gas is then condensed into a liquid before entering the expansion valve. The compressor helps maintain the flow of the refrigerant throughout the system, enabling the cycle to remove heat from the space being cooled.

This high-pressure, high-temperature gas is then condensed into a liquid form as it flows through the condenser coils. This process allows the system to release heat and cool the space.

In refrigeration, the symbol ( P_2 ) typically represents the pressure at the discharge or high-pressure side of the refrigerant system, specifically after the compressor. It is crucial for determining the efficiency and performance of the refrigeration cycle, as it influences the condensation process and overall system pressure. Maintaining the correct ( P_2 ) is essential for optimal operation and system reliability.
Vapor compression in the refrigeration cycle is the process which turns heated vapor into a cold liquid. This allows the coolant to flow through the condenser and cool the air.
The maximum temperature in a refrigeration cycle occurs at the condenser, where the high-pressure, high-temperature refrigerant gas releases heat to the surroundings and condenses into a liquid. This liquid coolant then passes through the expansion valve and evaporator in a continuous cycle to cool the desired space.
The purpose of the evaporator in the refrigeration cycle is to absorb heat from the space being cooled, causing the refrigerant to evaporate and turn into a gas. This process cools the air inside the space and allows the refrigerant to carry the absorbed heat to the compressor for further processing.
what are the six states of a refrigerant in a refrigeration cycle
In a refrigeration system, pressure is changed primarily at the compressor and the expansion valve. The compressor increases the pressure of the refrigerant vapor, raising its temperature and allowing it to release heat in the condenser. After the refrigerant condenses into a liquid, it passes through the expansion valve, where pressure is drastically reduced, allowing it to evaporate and absorb heat in the evaporator. This cycle of pressure changes is crucial for the refrigeration process.
