Abstract

The invention relates to the technical field of air conditioners, in particular to a liquid distributor, an evaporator and an air conditioning system. The liquid distributor aims at solving the problem that an existing liquid distributor is not uniform in liquid distribution. In order to achieve the purpose, the liquid distributor comprises an upper cover and an upper shell, a first liquid distribution cavity is defined between the upper cover and the upper surface of the upper shell, a plurality of first liquid distribution holes are formed in the position, located in the first liquid distribution cavity, of the upper shell, and a liquid inlet is formed in the upper cover; the upper cover is arranged in the length direction of the upper shell, the projection of the upper cover on the upper shell is in a trapezoid shape, and the liquid inlet is formed in the side, close to the lower bottom of the trapezoid, of the upper cover. The projection of the upper cover on the upper shell is arranged to be trapezoid, and the liquid inlet is formed in the side, close to the lower bottom of the trapezoid, of the upper cover, so that when a refrigerant flows, the kinetic energy of the refrigerant can be basically kept unchanged, and a better liquid homogenizing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and specifically provides a liquid distributor, an evaporator and an air conditioning system. Background technique [0002] In energy and chemical systems, uneven flow distribution is an important cause of system performance deterioration, device dysfunction, safety issues, product quality reduction, system life shortening, and cost increase. Therefore, ensuring uniform flow distribution of equipment is extremely important. Important issues. In the heat exchanger used in the field of air conditioning and refrigeration technology, compared with other types of evaporators, the horizontal tube falling film evaporator has the advantages of less refrigerant charge, high heat exchange efficiency and low operating cost. focus on. Taking the horizontal tube falling film evaporator as an example, the principle of the horizontal tube falling film evaporator is to let the refrigerant flow into th...
