Improved air conditioner capillary pipe structure

Abstract

The invention provides an improved capillary pipe structure of an air-conditioner, which comprises a condenser, an outlet tube and a capillary pipe, wherein the outlet tube is connected with the condenser; the capillary pipe is connected with the outlet tube; and at least two pipelines consisting of the outlet tube and the capillary pipe are arranged. Flow paths of the pipelines are similar or approximately the same. The capillary pipe of each pipeline is a structure leading temperature of an outlet to have condensate depression close to 8 degrees; lengths or the inner diameters of the capillary pipes of the pipelines can be different to ensure that the temperature of the outlet of each pipeline has the condensate depression at about 8 degrees. The capillary pipe structure has the characteristics that branch paths of the condenser can respectively control flow, so that flow distribution can be more even; because of separated control, the length of the capillary pipe can be corresponding times longer than the prior path, thereby avoiding the problem that the capillary pipe can not be shortened any more; furthermore, because the two paths do not need to be combined into one path, heat waste and flowed friction caused by mutual heat transmission are reduced, and heat transferring capability can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and relates to an air conditioner, in particular to a capillary structure of the air conditioner. Background technique [0002] Such as figure 1 As shown, because the existing air conditioner has only one capillary tube, it is necessary to control two or even multiple paths in the condenser 13, and the refrigerants of the four PASS (outlet pipes) of 10, 20, 30, and 40 all pass through the capillary tube 14 after summarizing. The capillary 14 controls the flow of the four channels through the change of length, which cannot guarantee the uniformity of liquid distribution in each channel. However, for systems with small condensers or very uniform distribution requirements, if the distribution in the refrigeration system is uneven, it will inevitably cause tube failure. The heat loss inside the circuit will affect the heat transfer efficiency. Moreover, in order to reduce the pressure,...

[0002] like figure 1 As shown, because the existing air conditioner has only one capillary tube, it is necessary to control two or even multiple paths in the condenser 13, and the refrigerants of the four PASS (outlet pipes) of 10, 20, 30, and 40 all pass through the capillary tube 14 after summarizing. The capillary 14 controls the flow of the four channels through the change of length, which cannot guarantee the uniformity of liquid distribution in each channel. However, for systems with small condensers or very uniform distribution requirements, if the distribution in the refrigeration system is uneven, it will inevitably cause tube failure. The heat loss inside the circuit will affect the heat transfer efficiency. Moreover, in order to reduce the pressure, the capillary needs to be shortened, but the production process requires that the capillary cannot be shortened indefinitely, so a contradiction arises. How to solve this contradiction needs to be resolved as soon as possible. The problem
