Question

In a Vapour Compression Refrigeration System (VCRS), if throttle valve is replaced with expansion cylinder, the COP will

• A. Increase
• B. Decrease
• C. Remain Same
• D. Not be predictable unless refrigerant used is known

Hint:

The COP of a refrigeration system is improved when expansion losses are minimized, such as by using an expansion cylinder instead of a throttle valve.

Answer 1

The Correct Option is A

Replacing the throttle valve with an expansion cylinder will improve the efficiency of the system, leading to an increase in the Coefficient of Performance (COP). The expansion cylinder allows for a more gradual and controlled expansion of the refrigerant, improving the thermodynamic efficiency.
