The four main stages of the refrigeration cycle, also known as the vapor-compression cycle, are:
1.Evaporation: This is where the refrigerant absorbs heat from the environment it’s trying to cool.
2.Compression: The compressor takes the low-pressure, low-temperature refrigerant vapor and compresses it into a high-pressure, high-temperature gas.
3.Condensation: The compressed hot gas then passes through the condenser, where it releases heat to the surrounding environment (usually outside air). As it loses heat, the refrigerant changes back into a liquid state.
4.Expansion: The high-pressure liquid refrigerant then passes through an expansion valve (also called a throttle valve or capillary tube). This valve rapidly decreases the pressure of the refrigerant, causing it to expand and cool down significantly.
REFRIGERTION CYCLE
Here’s a brief breakdown of each stage:
1. Evaporation:
- The evaporator, located in the area you want to cool (e.g., your refrigerator or room), contains the low-pressure refrigerant.
- The refrigerant absorbs heat from the surrounding air or objects, causing them to cool down.
- As the refrigerant absorbs heat, it evaporates (changes from a liquid to a gas) and becomes even colder.
2. Compression:
- The low-pressure, low-temperature refrigerant vapor then enters the compressor.
- The compressor is essentially a pump that increases the pressure of the refrigerant vapor.
- As the pressure increases, the temperature of the refrigerant also increases significantly.
3. Condensation:
- The high-pressure, high-temperature refrigerant gas then flows through the condenser, usually located outside the area you want to cool.
- The condenser is typically a series of coils with fins that help transfer heat to the surrounding environment (often with the help of a fan).
- As the hot refrigerant releases heat to the environment, it condenses (changes from a gas back into a liquid) and becomes cooler.
4. Expansion:
- The high-pressure liquid refrigerant from the condenser then passes through an expansion valve.
- This valve acts like a bottleneck, rapidly decreasing the pressure of the refrigerant as it flows through.
- This sudden pressure drop causes the refrigerant to expand rapidly. This expansion process requires energy, which is absorbed by the refrigerant itself, causing it to cool down significantly.
