    * Types of Evaporators Based on Defrosting and Shape of Construction — 2

    Types of Evaporators Based on Defrosting and Shape of Construction — 2 Types cooling coil based of frost formation (a) Frosting type—Used in frozen food cabinets (b) Defrosting type – Used in fridges. Defrosting was manual in earlier days. Presently it is automatic by using a heater in the evaporator with a timer. Say after […]
