Abstract

The invention relates to a liquid-distributing device for a falling-film evaporator used for a refrigerating system. The liquid-distributing device comprises a liquid inlet pipe, a flow branching pool, a flow-guiding pipe, a porous liquid-distributing pipe and a packing tank, wherein the liquid inlet pipe is connected with the flow branching pool; the flow branching pool is connected with the flow-guiding pipe; the flow-guiding pipe is connected with the porous liquid-distributing pipe; the porous liquid-distributing pipe is arranged in the packing tank; and a plurality of liquid-distributingholes are formed on a base plate of the packing tank. The evenness of refrigerating fluid distribution is promoted by the liquid-distributing device provided by the invention, thereby being capable of evenly distributing refrigerating fluid along a radial direction and a length direction of a heat exchange pipe bundle, avoiding the generation of a local drying phenomenon, reducing a demand on horizontality during a mounting process of a refrigerating machine set, efficiently promoting a coefficient of heat transfer of the falling-film evaporator, saving space and capitalized cost, and achieving higher applicability.

Description

【Technical field】 [0001] The invention relates to the field of air conditioning, in particular to a liquid distribution device for a falling film evaporator of a refrigeration system. 【Background technique】 [0002] Horizontal tube falling film evaporators have been widely used in chemical, petrochemical, seawater desalination and other industries, but their application in refrigeration systems has not yet been popularized. In recent years, due to the increasing energy crisis and environmental problems, improving the efficiency of refrigeration systems has become the focus of attention. As a new type of evaporator, the falling film evaporator has the advantages of high heat exchange efficiency, small equipment volume, low equipment cost, small refrigerant charge and good oil return performance. It has good application prospects in refrigeration and air conditioning systems. The main heat exchange method inside the horizontal tube falling film evaporator is falling film eva...
