The present embodiment provides an air conditioner that performs a cooling and heating cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The cooling and heating cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies a refrigerant medium to the air that has been conditioned and heat-exchanged.
The compressor compresses a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.
The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner includes a portion of an indoor heat exchanger and an indoor fan, and a throttling device (e.g., a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioner performs a heating mode when the indoor heat exchanger serves as a condenser, and performs a cooling mode when the indoor heat exchanger serves as an evaporator.
The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein again.
The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (an evaporator at the moment in the indoor unit) to be in an ultralow-pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled through the coil pipe of the indoor heat exchanger to become cold air which is blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (a condenser at the moment in the outdoor unit) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved through circulation.
The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at this time), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, thereby achieving the purpose of increasing the indoor temperature. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs the heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.
For the indoor heat exchanger and the outdoor heat exchanger, a plurality of refrigerant pipes which are arranged in parallel are configured, in order to distribute the refrigerant uniformly, a flow divider is arranged on the heat exchanger, and the flow divider is used for distributing the refrigerant uniformly to the refrigerant pipes which are arranged in parallel.
In accordance with some embodiments of the present application, a flow splitter, as illustrated with reference to fig. 1-4, includes:
the liquid inlet pipe 1 is used for inputting a refrigerant;
a reflection container 2 having an inlet (not shown) and a plurality of outlets (not shown) provided on an installation end surface of the reflection container 2;

wherein, the liquid inlet pipe 1 is connected with the inlet, and the liquid outlet pipe 3 is connected with the corresponding outlet; along the refrigerant flow direction, the liquid inlet pipe 1 extends towards the installation end face, and the liquid outlet pipe 3 extends away from the installation end face.
Specifically, taking the air conditioner as an example, during the operation of the air conditioner, the compressor starts to compress and convey the refrigerant, the refrigerant flows into the reflecting container 2 through the liquid inlet pipe 1, and the refrigerant enters the reflecting container 2 and then impacts the inner wall surface of the reflecting container 2, which is arranged opposite to the installation end surface.
After impacting the inner wall surface of the reflection container 2, the refrigerant flowing at a high speed flows in the reverse direction under the blocking of the inner wall surface, and after being subjected to reflection treatment by the inner wall surface of the reflection container 2, the refrigerant enters each outlet arranged on the mounting end surface, and finally, the refrigerant is output from each liquid outlet pipe 3.
The refrigerant is distributed to the liquid outlet pipes 3 in a reflection mode, on one hand, the reflected refrigerant is less influenced by gravity, the refrigerant can be more uniformly distributed, so that the refrigerant conveying capacity of the liquid outlet pipes 3 is more uniform, and the condition of uneven refrigerant distribution caused by the fact that the liquid distributors are obliquely or transversely arranged is reduced; on the other hand, after the refrigerant entering the reflecting container 2 is impacted, the gas-liquid phase mixing degree can be improved, and further, the phenomenon of gas-liquid phase layering of the refrigerant caused by gravity during inclined installation can be weakened.
Through setting up the reflection container, after the refrigerant that carries to the feed liquor pipe enters into the reflection container, the refrigerant will strike the inner wall of reflection container and each drain pipe of backward flow direction, to the refrigerant of distributing in each drain pipe, owing to adopt the reflected mode to distribute, the refrigerant that flows at a high speed enters into each drain pipe with the mode of reflection, and then can reduce the condition emergence that causes the refrigerant uneven distribution because of the gesture slope of shunt, realize shunt evenly distributed refrigerant, in order to improve the heat exchange efficiency of air conditioner.
In some embodiments of the present application, along the refrigerant flow direction, a pipe diameter tapered section 101 is provided in the liquid inlet pipe 1.
Specifically, for the refrigerant flowing through the liquid inlet pipe 1, in order to increase the flowing speed of the refrigerant more effectively, a pipe diameter reducing section 101 is provided in the liquid inlet pipe 1.
In the flowing process of the refrigerant in the liquid inlet pipe 1, after the refrigerant flows into the pipe diameter reducing section 101, the flow velocity of the refrigerant is increased due to the fact that the diameter in the pipeline is reduced, and finally the flow velocity of the refrigerant entering the reflection container 2 is increased.
After the refrigerant enters the reflection container 2 in an accelerated manner, the refrigerant flowing at a high speed can generate more violent impact, so that the refrigerant has a better reflection flowing effect. Meanwhile, the high-degree refrigerant is more beneficial to fully mixing two-phase refrigerants in the refrigerant so as to improve the heat exchange capacity.
In an embodiment of the present application, the cross-section of the liquid inlet pipe 1 located on the inner pipe wall of the pipe diameter reducing section 101 is an arc-shaped structure.
Specifically, pipe diameter convergent section 101 adopts smooth transition's mode to realize reducing of pipe diameter, and the arcwall face can be more smooth-going guide refrigerant flow, like this, at refrigerant accelerated flow in-process, can not produce too big flowing noise because of sudden necking down suddenly of pipeline.
In another embodiment of the present application, the liquid inlet pipe 1 further has a liquid inlet section 102 and an acceleration section 103; along the refrigerant flow direction, liquid inlet section 102, pipe diameter reducing section 101 and accelerating section 103 are arranged in sequence, and the inner diameter of liquid inlet pipe 1 located in liquid inlet section 102 is greater than the inner diameter of liquid inlet pipe 1 located in accelerating section 103.
Specifically, the liquid inlet pipe 1 adopts a necking structure, so that the liquid inlet pipe 1 sequentially forms a liquid inlet section 102, a pipe diameter reducing section 101 and an accelerating section 103 along the conveying direction of the refrigerant, and the refrigerant can be conveyed at an accelerated speed.
When the gas-liquid two-phase refrigerant enters the pipe diameter reducing section 101 from the liquid inlet section 102, the flow velocity of the refrigerant is increased due to the reduction of the flow channel, and the maximum flow velocity is obtained at the accelerating section 103, so that the flow pattern of the refrigerant at the position is reformed into a better symmetrical flow pattern.
In some embodiments of the present application, a reflective groove 21 is provided in the reflective container 2, and the reflective groove 21 is disposed opposite to the inlet.
Specifically, in order to improve the reflection effect of the refrigerant, the reflection container 2 is provided with a reflection groove 21, and the reflection effect of the refrigerant is improved by the reflection groove 21.
After the refrigerant enters the reflection container 2 from the liquid inlet pipe 1, the refrigerant rushes into the reflection groove 21, and the refrigerant can be blocked and then output along the edge of the reflection groove 21 by utilizing the concave structure of the reflection groove 21, so that the refrigerant is reflected and output better.
The refrigerant is reflected and output through the reflection groove 21, so that the impact influence of the reflected refrigerant on the refrigerant which just enters the reflection container 2 can be effectively reduced, the reflection effect is further improved, and the refrigerant is finally optimized to be uniformly distributed to the liquid outlet pipes 3.
Wherein, the cross section of the reflection groove 21 is a V-shaped structure or an arc structure. Specifically, the reflective groove 21 is a V-shaped structure.
The refrigerant directly shoots into the reflecting groove 21, the refrigerant is blocked in the reflecting groove 21 with the V-shaped structure and finally reflected, the two-phase fluid after reflection is further uniformly mixed, and the two-phase fluid flows to the liquid outlet pipe 3 along the outer edge of the reflecting cavity formed in the reflecting groove 21. On one hand, the refrigerant continuously flows out to the liquid outlet pipes 3 in a better symmetrical flow pattern under the inertia effect, so that the distribution uniformity is improved, and on the other hand, the flow velocity of the refrigerant is properly reduced when the refrigerant flows in the reflection groove 21, so that the increase of the flow noise is avoided.
Wherein, the central line of the liquid inlet pipe 1 and the central line of the reflecting groove 21 can be arranged in a collinear way,
in an embodiment of the present application, the liquid outlet pipes 3 are uniformly distributed on the periphery of the liquid inlet pipe 1 and are arranged in a divergent manner inclined with respect to the liquid inlet pipe 1, and the central lines of the liquid outlet pipes 3 extend into the reflection grooves 21.
Specifically, the liquid outlet pipes 3 are arranged in a mode of uniformly distributing around the liquid inlet pipe 1, so that different refrigerants can be uniformly output through the liquid outlet pipes 3 at different positions.
And, the liquid outlet pipe 3 is arranged obliquely with respect to the liquid inlet pipe 1 such that the center line of the liquid outlet pipe 3 extends into the reflection groove 21. Therefore, the reflected refrigerant can enter the liquid outlet pipe 3 more smoothly.
