If a heat exchanger is designed to condense refrigerant vapor using central cooling fresh water as a condensing medium, what statement is true?

AI Explanation
The correct answer is C) The refrigerant vapor loses latent heat, the central cooling fresh water gains sensible heat. In a heat exchanger designed to condense refrigerant vapor using central cooling fresh water, the refrigerant vapor loses its latent heat of vaporization as it condenses into a liquid. This latent heat is then transferred to the central cooling fresh water, causing it to gain sensible heat and increase in temperature. The other options are incorrect because they do not accurately describe the heat transfer process in this type of heat exchanger.
