And it’s an important component of refrigeration system and air conditioning system. The advantage of the plate type of evaporators is that they are more rigid as the external plate provides lots of safety. Lesson 3 - Improving Evaporator Performance Topics: Evaporator is said to be flooded type if liquid refrigerant covers the entire heat transfer surface. Heated air is forced through and past the fins and tubes of the evaporator. As the cold refrigerant passes through the evaporator coil, heat moves from the warm air into the cooler refrigerant. Additionally, he has interested in Product Design, Animation, and Project design. Clicks:4790 Evaporator is an equipment by heating the solution to make it concentrated or precipitate grains from it . Agitated Thin Film Evaporators. The flow of the refrigerant to these chillers is controlled by the expansion valve. Steam Jacket is also attached to a condensate outlet and vent for non-condensable gases. In this type of evaporator, the liquid flows as a thin film on the walls of long (from 12 to 30 feet in length) and vertical heated tube. In these systems the finned evaporator is popularly known as the cooling coil. Chapter Four – Types of Wastewater Evaporators. The third group is a unique classification and the direct-fired, submerged combustion evaporator is the best example of this type. 3) Film evaporator Types: i) Wiped Film evaporator ii)Long Tube Evaporator a) Climbing film evaporator b) Falling film evaporator Types of Evaporators. Introduction to Seals : A multiple effect system (Fig 2) uses the vapor from the first effect as the steam source for each subsequent effect. The expansion valve controls the rate of flow of refrigerant to the evaporator in such a way that all the liquid is vaporized and the vapor is also superheated to a limited extent by the time it reaches the outlet end. The level of liquid refrigerant is maintained constant in the surge chamber by using float control. This type of evaporator uses a float type of expansion valve. In the generator the absorbent is heated. The heating area is limited and decreases in proportion to the increase in the size of the Pan. Thus the evaporator in its length is filled with a varying proportion of liquid and vapor. In some cases, the fins are soldered directly to the surface of the coil and in other cases, the fins are just slipped over the surface of the fins, and then they are expanded thus ensuring close thermal contact between the two. The evaporators used for the refrigeration and the air conditioning applications have different types of construction depending on the application. The hot room air flows over the finned evaporator or the cooling coil, gets chilled and enters the room to produce the cooling effect. These are generally much smaller and simpler than the tubular evaporation systems, and are often batch or multipurpose evaporators.
