Title:
LIQUID DISTRIBUTOR, FALLING FILM EVAPORATOR, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/006992
Kind Code:
A1
Abstract:
A liquid distributor (200), a falling film evaporator (10), and an air conditioner. The liquid distributor (200) comprises a liquid distributing slot (210) and a liquid stopping slot (220). Multiple liquid distributing through holes (211) are disposed at a bottom wall of the liquid distributing slot (210). A top space of the liquid distributing slot (210) communicates with a vent channel (500) of the falling film evaporator (10). The liquid stopping slot (220) is disposed above the bottom wall of the liquid distributing slot (210). The liquid stopping slot (220) comprises two opposing side walls. The two opposing side walls on the liquid stopping slot (220) are each provided with multiple overflow through holes (221). A top space of the liquid stopping slot (220) communicates with the vent channel (500) of the falling film evaporator (10). A refrigerant can be injected into the liquid stopping slot (220). A gas-liquid mixed refrigerant undergoes primary gas-liquid separation and secondary gas-liquid separation while entering the liquid stopping slot (220) and the liquid distributing slot (210), so as to effectively reduce the amount of gaseous refrigerant mixed in a liquid refrigerant flowing from the bottom wall of the liquid distributing slot (210), thereby ensuring that the liquid refrigerant forms an even and stable liquid film on the surface of a heat exchange tube (310), and improving heat exchange efficiency of the falling film evaporator (10).
