Dispenser

Abstract

The invention discloses a dispenser, which comprises a shell, a side plate enclosing the shell, a distribution port penetrating the side plate and used for connecting a capillary tube, and a refrigerant pipe communicated with the shell, wherein the diameter of the distribution port is greater than that of the capillary tube, and a reducer pipe is arranged between the distribution port and the capillary tube. A baffle with a through hole is arranged in a cavity, and the baffle disperses a refrigerant while buffering a refrigerant stream in order to realize uniform distribution of the refrigerant. Meanwhile, the diameter of the distribution port is increased, and the reducer pipe is arranged between the distribution port and the capillary tube, so the welding difficulty is reduced, pipe deformation or leakage caused by welding is prevented; meanwhile, by the large-diameter distribution port, the non-uniform distribution of the refrigerant nearby the distribution port is further reduced, so the distribution of the refrigerant inside the capillary tube is improved. The purpose of distributing liquid uniformly is really achieved, so capillary tubes are balanced; moreover, by the structure, the noise is reduced, and the user satisfaction degree is increased.

Description

technical field [0001] The invention relates to a freezing system, in particular to a liquid separator of the freezing system. Background technique [0002] Generally, the refrigeration system is applied to refrigerators, refrigerators, air conditioners, etc., and uses the pressure and temperature change characteristics of the refrigerant to provide cooling or heating effects. [0003] figure 1 It is a composition diagram of the prior art refrigeration system. Such as figure 1 As shown, this refrigeration system is used in air conditioning systems. The refrigeration system of the air conditioner includes: a compressor 100; an evaporator 500; a condenser 200; a capillary 400 as an expansion device; [0004] The compressor 100 uses mechanical compression to compress the refrigerant gaseously into a high-temperature and high-pressure state and discharges it. The condenser 200 exchanges heat between the air sent by the blower fan 220 and the refrigerant compressed by the com...

Problems solved by technology

[0010] However, in the actual operation of the existing liquid separator, the flow rate of the refrigerant in the condenser of the outdoor unit of the air conditioner is too fast, and the diameter of the capillary is very small, which makes it difficult to distribute the refrigerant evenly and stably, so that the air conditioner ( Especially for heating) there will be a very unbalanced refrigerant entering the various pipes of the condenser, resulting in a very low local temperature during the heating process, resulting in icing and defrosting, which will affect the normal operation of the machine

[0011] Moreover, because the diameter of the capillary is very small, the diameter of the distribution port is also very good. It is difficult to operate during welding, and it is easy to cause blockage, deformation of the capillary or lax welding, resulting in refrigerant leakage.
