Starting from the evaporator, what is the correct sequence of flow in a refrigeration cycle?

In a refrigeration cycle, the sequence of flow begins at the evaporator. The refrigerant absorbs heat from the surroundings and evaporates into a vapor form. This vapor is then directed to the compressor. The compressor's role is to increase the pressure of the vapor, making it a high-pressure gas which is subsequently moved to the condenser.

In the condenser, the high-pressure gas releases its heat to the environment and condenses back into a liquid state. After the condenser, the refrigerant, now in liquid form, passes through the expansion valve. This valve reduces the pressure of the refrigerant, allowing it to expand and cool before it re-enters the evaporator to start the cycle again.

Thus, the correct sequence of the refrigeration cycle is: evaporator, compressor, condenser, and expansion valve. This flow path highlights how the continuous process works to transfer heat and maintain a desired cooling effect. Understanding this cycle is essential for anyone in the field of refrigeration and air conditioning.
