Another type of evaporator used in chiller systems is a falling film evaporatorIn a falling film evaporator the evaporator tubes are positioned typically below a distribution manifold from which refrigerant is urged forming a falling film on the evaporator tubes utilizing gravity to drive the flow of refrigerant over the evaporator.
Apr 30 2020nbsp018332Falling film chillers are also called spray chillersThe refrigerant of the evaporator of the falling film chiller is sprayed from the upper part of the heat exchange tube onto the heat exchange tubeThe refrigerant only forms a thin layer on the heat exchange tube.
Apr 30 2022nbsp018332Falling film evaporators provide increased chiller efficiency and simplicity over a traditional flooded evaporator designWhen mixed with water glycol slows the rate of freezing and helps to maintain temperature consistency in the application.
Aug 02 1996nbsp018332Many falling film evaporators deposit an excess of refrigerant on the top of the bundle to ensure complete wetting of the heat exchange surface from top to bottomThe excess liquid refrigerant that inevitably reaches the bottom of the evaporator vessel is collected in a sump then recycled from the sump to the top of the tube bundle.
Compression refrigeration apparatus for removing heat from a heat load using a falling film evaporator operated with an azeotropic refrigerant and utilizing a spray tree distribution system that distributes a refrigerant film on a heat exchange surface by spraying liquid refrigerant onto a surface and allowing the refrigerant to drip onto the primary heat exchange surface.
Dec 23 2020nbsp018332Falling film evaporator is the refrigerant is evenly distributed to the surface of the heat exchange tube through a liquid separator designed on the top forming a filmlike evaporation and efficient heat exchange with the medium in the tube.
Falling film horizontal tube evaporators for refrigeration equipment are an interesting alternative to pool boiling evaporators concerning operation costs safety thermodynamic efficiency charge of refrigerant or sizePlenty of literature works studied falling film evaporation but for its application in fields such as desalination and.
In falling film evaporators saturated twophase refrigerant is distributed over an evaporator tube bundle both in an axial direction along a length of the tube bundle and a lateral direction over a width of the tube bundlePoor or uneven distribution results in reduced efficiency of the evaporator which is compensated for by utilizing larger.
In some embodiments the fallingfilm evaporator further includes an evaporator inlet pipe the evaporator inlet pipe being in communication with the gasliquid separation chamber.
Oct 07 2009nbsp018332A new technology i have seen is fallin film evaporatorsThis has a small pup which pumps the liquid refrigerant in the bottom of the evap to a distributor plate on the top which coats the tubes in refrigerant by dripping the refrigerant like a shower headThis raises the efficiency of heat transfer and uses less refrigerant.

One feature of a compression refrigerator is that typically the bundle of pipe carrying the heat load in the evaporator is immersed in a standing body of the liquid refrigerantThis type of evaporator is called a flooded evaporatorIs exemplary of this type of evaporator is assigned to the assignee of the present invention and is incorporated by reference herein.
Recently introduced chiller family based on Turbocor oilfree compressors and distinguished by high energy efficiency and environmental safety received fallingfilm evaporators in addition to flooded models.
The Falling Film Evaporator with capacity ranges of up to 150th and relatively small floor space requirement is the most widely used evaporator in the process industryParticularly well suited for temperaturesensitive products liquids containing small quantities of solids and with a low to moderate tendency to form incrustations.
The present disclosure relates to heating ventilating air conditioning and refrigeration HVACampR systems and specifically to a fallingfilm evaporator with a gasliquid separation chamber suitable for a low pressure refrigerant.
The simple hybrid fallingfilm design uses copper tubes that are sprayed with refrigerant to reduce refrigerant charge while maintaining performanceShare Originally published in HPAC Engineering this article by Ian Casper of Johnson Controls outlines the benefits of falling film evaporators – namely efficiency and simplicity – over a.
