Byadmin

REFRIGERATION CONDENSERS & EVAPORATORS MULTIPLE CHOICE  QUESTIONS (MCQ) WITH ANSWERS   Condensers and evaporators are phase change equipment’s. Condensers change vapors into liquid on cooling. Evaporators convert liquid into vapors by consuming heat. Dry evaporators are used in domestic units. These ensure that only super heated vapor goes to the compressor for its safety. Flooded evaporators…
