Embodiment 2

[0037] In this embodiment, on the basis of the above implementation, the gas-liquid separator 3 is provided with a heating device 4, such as figure 1 As shown, the pressure in the gas-liquid separation pipe 30 is increased by the heating device 4 and the temperature of the refrigerant entering the liquid separator 2 is increased to extend the defrosting cycle of the heat exchanger 1 and optimize the heating effect of the unit. The heating device 4 is arranged on the electric heating belt outside the gas-liquid separator 3 . The electric heating belt is arranged in the middle of the gas-liquid separator 3 .

[0038] In this embodiment, the length of the gas-liquid separator 3 is replaced by 0.4 times the height of the heat exchanger 1 . The diameter of the gas-liquid separator 3 is replaced by 4 times of the gas collector. The liquid distribution port 22 in the liquid distribution head 2 is arranged upward and the refrigerant outlet 32 ​​of the gas-liquid separator 3 is highe...

Embodiment 3

[0040] Further, on the basis of the above implementation 1 or 2 in this embodiment, the gas-liquid separator 3 in the liquid separator assembly is vertically arranged, and the refrigerant outlet 32 ​​of the gas-liquid separator 3 is higher than the Bottom of heat exchanger 1. In this embodiment, the length of the gas-liquid separator 3 is replaced by 0.6 times the height of the heat exchanger 1 .

Abstract

The invention relates to the field of air conditioners, in particular to a liquid distributor assembly and an air conditioner comprising same. The liquid distributor assembly comprises a liquid distributing head, wherein a liquid collecting hole is formed in one end of the liquid distributing head; a plurality of liquid distributing holes are formed in the other end of the liquid distributing head; the liquid distributing holes communicate with a liquid distributing tube of a heat exchanger; a gas-liquid separator with a refrigerant outflow hole is arranged at the upstream side of the liquid collecting hole; and the refrigerant outflow hole communicates with the liquid collecting hole. In order to solve the technical problems that a liquid distributor in the prior art is uneven in frosting and defrosting and is not good in heating effect as a gas-liquid mixture entering each liquid distributing tube of a heat exchanger is inconsistent in proportion, the invention provides the liquid distributor assembly which is more even in frosting and defrosting and is better in heating effect as well as the air conditioner comprising the liquid distributor assembly.

Description

technical field [0001] The invention relates to the field of air conditioners. Specifically, it relates to a liquid separator assembly and an air conditioner thereof. Background technique [0002] The liquid distributor is responsible for evenly distributing the refrigerant in the heat exchanger. If the distribution is uneven, some branch refrigerants will be too much. As a result, the evaporation is not complete, and the liquid flows out of the evaporator, and some branch refrigerants If it is too small, the heat transfer area of ​​the heat exchanger cannot be fully utilized. [0003] For the heat pump air conditioning system, the outdoor heat exchanger becomes an evaporator during heating. When the traditional heat pump air conditioner is heating and running, the liquid refrigerant passes through the electronic expansion valve, and the pressure drops, so there is more or less part of the refrigerant The gaseous refrigerant, after coming out of the electronic expansion va...
