An evaporator is a device or system that turns liquid into vapor by applying heat. This process concentrates solutions, facilitates drying, or cools environments by removing heat and moisture. In HVAC (heating, ventilation, and air conditioning) systems, evaporators absorb heat from the environment to aid in cooling. In industrial applications, they are used to concentrate fluids by evaporating the solvent, usually water. Types of Evaporators Evaporators come in various designs, each tailored to specific applications and operating conditions. The main types include: 1. Natural Circulation Evaporators Rely on natural convection currents to circulate liquid. Common in simple processes like salt production or small-scale concentration. 2. Forced Circulation Evaporators Use pumps to force liquid circulation through the heating element. Suitable for viscous or scale-forming liquids. 3. Rising/Falling Film Evaporators Utilize thin film flow over heated surfa...
