1.	In a chilled water system, the refrigerant is used to cool the air directly while in the direct expansion system, a secondary medium like water is used to cool the air.(a) True(b) FalseI have been asked this question in my homework.I would like to ask this question from Systems and Essentials of Air Conditioning System topic in portion Air Conditioning, Thermal Insulation, Stones & Ferrous Metals of Construction & Building Materials
Answer» Correct option is (b) False Easy EXPLANATION: In the direct expansion system, the refrigerant is used to cool the air directly while in the chilled WATER system, a secondary medium like water is used to cool the air. In the chilled water system, the refrigerant FIRST COOLS the water and then the water cools the air.
