Which effect arises when refrigerant mass flow in a heat pump evaporator reduces because of obstruction?

💡 Explanation

When refrigerant mass flow reduces, the refrigerant absorbs less heat, resulting in lower evaporator pressure because of reduced latent heat transfer; this lowers system efficiency. Therefore, decreased coefficient of performance results, rather than increased compressor temperature, lower superheat, or higher subcooling that require different flow changes.
