24/1/2022· A falling film evaporator is a type of heat exchanger that uses a shell and tube design to evaporate heat-sensitive liquids. The feed is pumped into the evaporator from the top. It’s then uniformly dispersed throughout the heating tubes of the device. While partially evaporated, the liquid flows through tubes, forming a thin layer on the tube
24/2/2022· Instead, the UA value does not depend on the evaporator inlet chilled water temperature and initial mass content inside the evaporator. UA is 540–570 W/K for temperatures of chilled water entering the evaporator, equal to 10–20 °C, and mass of refrigerant of 0.9–1.5 kg. View Full-Text. Keywords: adsorption chillers; silica gel; water

1/4/2020· A method for measuring the contact angle of the refrigerant falling film evaporation process is proposed. •. The contact angle increases as the wall superheat increases in the evaporation process. •. The relationship between the contact angle of R134a and the wall superheat is evaluated, and a correlation is developed.
Working principle. For the thermal separation of a mixture a thin film is produced at the heated wall of a cylindrical or conical evaporator. A distribution ring on the rotor distributes the liquid evenly across the periphery. Then, the blades fitted at the rotor spread the liquid as a thin film of min. 0.5 mm over the heat transfer surface.

Working principle of falling film evaporators. A falling film evaporator is essentially a shell & tube type of heat-exchanger used to evaporate heat sensitive liquids. The feed enters the evaporator through the top of the unit. It is then distributed evenly in the unit’s heating tubes. The liquid flows through tubes and forms a thin film on
Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a coination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray
1/6/1998· Abstract. Heat transfer coefficients for evaporation of single-component liquids in falling films were experimentally measured over an extended range of parameters. By using two different fluids (propylene glycol and water), over a range of absolute pressures, it was possible to extend the existing data base by an order of magnitude in Prandtl
7/5/2021· In a cliing film evaporator, tubes are heated externally by steam. The preheated feed enters from the bottom and flows up through the heated tubes. The liquid gets heated rapidly due to the enhanced overall coefficient of the preheated feed.) The liquid near the wall becomes vapor and forms small bubbles. These tend to fuse to larger bubbles
