Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the liquid distributor, falling film evaporator and air conditioner of the present invention will be further described in detail through the following examples and in conjunction with the accompanying drawings.

[0051] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only. Various objects in the drawings of the embodiments are drawn to a s...

Abstract

The invention relates to a liquid distributor, a falling-film evaporator and an air conditioner. The liquid distributor comprises a liquid homogenizing tank and a liquid stopping tank, wherein the bottom wall of the liquid homogenizing tank is provided with a plurality of liquid distribution through holes; the top space of the liquid homogenizing tank communicates with an air exhaust channel of the falling-film evaporator; the liquid stopping tank is arranged above the bottom wall of the liquid homogenizing tank; the liquid stopping tank comprises two opposite side walls; the two opposite sidewalls of the liquid stopping tank are separately provided with a plurality of overflow through holes; the top space of the liquid stopping tank communicates with the air exhaust channel of the falling-film evaporator; and a refrigerant can be injected into the liquid stopping tank. The gas-liquid mixing refrigerant can be separately subjected to primary gas-liquid separation and secondary gas-liquid separation in a process of entering into the liquid stopping tank and the liquid homogenizing tank, so that inclusion contents of the gaseous refrigerant in the liquid-state refrigerant which flows out of the bottom wall of the liquid homogenizing tank can be effectively reduced, so that the phenomenon that a uniform and stable liquid film of the liquid-state refrigerant is formed on the surface of a heat exchange pipe is ensured, and the heat exchange efficiency of the falling-film evaporator is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a liquid distributor, a falling film evaporator and an air conditioner. Background technique [0002] During the working process of the falling film evaporator, the refrigerant in the gas-liquid mixed state enters the liquid distributor in the falling film evaporator from the top. user. After the liquid refrigerant itself is evaporated, it enters the suction port of the compressor, is compressed and then discharged into the condenser. The formation of a uniform and stable liquid film covering the surface of the heat exchange tube by the liquid refrigerant is a necessary condition to ensure sufficient heat exchange in the falling film evaporator. The refrigerant in the gas-liquid mixed state in the traditional falling film evaporator is not easy to separate, and the liquid refrigerant cannot form a uniform and stable liquid film on the surface of the heat exchang...
