The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Refrigerant thermodynamic properties determine the mechanical dimensions and displacement requirements of vapor compression refrigeration components.
Step 2: Detailed Explanation:
Specific volume ($v$, in $\text{m}^3/\text{kg}$) is the volume occupied by unit mass of refrigerant vapor entering the compressor suction.
A low suction specific volume means less volumetric displacement is required to pump a given mass flow rate of refrigerant to achieve the desired cooling capacity.
This directly minimizes the required cylinder swept volume and physical size of the compressor.
Step 3: Final Answer:
Thus, low specific volume of refrigerant vapor reduces the size of the compressor.
