← TechnologyWhich consequence results when refrigerant permeability increases in HVAC?
A)Ice buildup on evaporator increases
B)Compressor experiences lubricant dilution ✓
C)Lower superheat increases efficiently
D)Cooling cycle pressure ratio equalizes
💡 Explanation
Compressor lubricant dilution results from increased refrigerant permeability because this leads to more refrigerant dissolving into lubricating oil within the compressor via the mechanism of preferential solubility; therefore the lubricant thins, rather than causing inefficiencies or pressure changes.
