Detailed description of the invention
The drawings herein are incorporated into the specification and forms part of this specification, and shows the implementation for meeting the disclosure
Example, and consistent with the instructions for explaining the principles of this disclosure.
Fig. 1 is a kind of knockout structural representation for air conditioner refrigerating provided by the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one
As shown in Figure 1, the present invention provides a kind of dispenser for air conditioner refrigerating, including inlet 1 and the inlet
The liquid separation room 2 of 1 connection, and the liquid outlet 3 being connected to the liquid separation room 2, be provided in the liquid separation room 2 first mixing chamber 4,
The of several the first branch pipes 5 being arranged in an axially parallel mode along the liquid separation room 2 and the axially vertical setting along the liquid separation room 2
Two branch pipes 6,1 two sides of inlet are arranged two pieces of partitions 7, form one section between two pieces of partitions 7 and be open, in the opening
It is provided with restricting orifice 8, first branch pipe 5 is provided with the second liquid outlet 9 close to open at one end, on second liquid outlet 9
Be provided with electric control valve 10 and pressure sensor 11, second branch pipe 6 close to 5 side of the first branch pipe setting second into
Third liquid outlet 13 is arranged in liquid mouth 12, the other side, and the branch pipe is gradually shunk inwardly close to one end of opening, is in rotary table
Shape, the length of the partition 7 is slightly longer than the branch pipe, and the partition 7 gradually shrinks shape far from one end of inlet 1 inwardly
At a bit of opening, the open height is the 1/2 of 1 height of inlet.
Specifically, gas-liquid two-phase cold-producing medium flows into the first branch pipe 5 from inlet 1, and the length of first branch pipe 5 can root
It is configured according to requirement, the length of runner determines gas-liquid two-phase fluid mixture homogeneity.First branch pipe 5 is not
Uniform cylindrical shape is conventionally made, but in a circular table shape, so set, refrigerant goes out flowing to second from inlet 1
During liquid mouth 9, since the radius of runner is gradually reduced, the flow velocity of refrigerant is gradually increased, and is conducive to the uniform mixed of gas-liquid
It closes.Forming cavity between each first branch pipe 5, refrigerant is after second liquid outlet 9 outflow, into the cavity,
Gas-liquid turbulent flow is formed in the cavities, realizes secondary mixing, improves the gas-liquid mixed uniformity again.The refrigerant is in the cavity
Enter the second branch pipe 6, rectangular-shaped, the cavity volume of the setting of the second branch pipe 6 growth from the second inlet 12 after interior turbulent flow
Larger, inside hoards a large amount of refrigerating fluids, and a large amount of refrigerant moments flow into from the second inlet 12, causes in second branch pipe 6
Portion's pressure increases, and compresses to the refrigerating fluid of entrance, improves the gas-liquid mixed uniformity again, realizes that third time mixes, mixing
It is flowed out after uniformly from third liquid outlet 13, the mixture homogeneity of gas-liquid two-phase cold-producing medium at this time is ideal.
The present invention is provided with restricting orifice 8 between the first mixing chamber 4 and the second mixing chamber 14, from the third liquid outlet
The refrigerant of 13 outflows improves the kinetic energy of refrigerant due to section sudden contraction by the restricting orifice 8, and flow velocity increases,
When passing through restricting orifice 8, two sides form pressure difference, and the second mixing chamber 14 is provided on rear side of the restricting orifice 8, high speed
Refrigerant produces vortex after entering second mixing chamber 14, so that refrigerant air-liquid two-phase be made to be sufficiently mixed, realization the
Four mixing.
Embodiment two
Electric control valve 10 and pressure sensor 11 are provided on second liquid outlet 9, second branch pipe 6 is close to institute
It states 5 side of the first branch pipe and the second inlet 12 is set, third liquid outlet 13 is arranged in the other side, and the pressure sensor 11 is for surveying
The pressure value of gas-liquid near two liquid outlet 9 of flow control.
The gas-liquid two-phase cold-producing medium that expansion valve comes is entering each first branch pipe 5 by inlet 1, because each first
5 pressure drop of branch pipe is much larger than the pressure drop of evaporator, and the caliber of each first branch pipe 5 is identical with length, so having phase on each branch pipe
Same resistance, can flow into the refrigerant of equivalent, but in actual operation, the resistance of each branch pipe is different, and is caused each
The difference of branch pipe liquid supply rate, so pressure sensor 11 is arranged in each mouth of pipe in the present invention, the pressure sensor 11 is used for
Detect each mouth of pipe pressure.
Specifically, the pressure value that each pressure sensor 11 will test is real-time transmitted to remote terminal, remote terminal root
Judge whether the resistance in each branch pipe is identical according to the pressure value received, if judging the pressure that some pressure sensor 11 is sent
When force value has abnormal, then control signal, the electric control valve 10 are exported to the corresponding electric control valve 10 of pressure sensor 11
According to the aperture of the second liquid outlet of control Signal Regulation 9 received.For example, there is a pressure value less than normal, remote terminal is to the pressure
The corresponding electric control valve 10 of force snesor 11 exports first control signal, and the electric control valve 10 reduces opening for the second liquid outlet 9
Degree increases the pressure in corresponding branch pipe by reducing the flow of the second liquid outlet 9, reaches the mesh for balancing each branch pipe internal drag
's；If there is a pressure value bigger than normal, remote terminal is believed to the second control of the corresponding electric control valve 10 of pressure sensor 11 output
Number, the electric control valve 10 increases the aperture of the second liquid outlet 9.

As shown in Figure 1, the second mixing chamber 14 being connected to the restricting orifice 8 is additionally provided in the liquid separation room 2, it is described
The other end of second mixing chamber 14 is connected to liquid outlet 3, and second mixing chamber 14 is being in rib close to described 8 one end of restricting orifice
Mesa-shaped, second mixing chamber 14 are provided with several the rectangular close to 3 one end of liquid outlet in second mixing chamber 14
One baffle 15 and several second baffles 16, the first baffle 15 is set in distance with the second baffle 16 and plate length is small
In the height of the second mixing chamber 14, the upper end of the first baffle 15 and second mixing chamber 14 are fixed, lower end and described the
Two mixing chambers 14 form opening；The upper end of the second baffle 16 and second mixing chamber 14, which are formed, to be open, lower end with it is described
Second mixing chamber 14 is fixed, the first baffle 15 and the second baffle 16 in vertical direction with 30 ° of angles, and two-by-two it
Between keeping parallelism.
Specifically, gas-liquid two-phase cold-producing medium from restricting orifice 8 outflow after enter rear the second mixing chamber 14, described second
The first baffle 15 and second baffle 16 being spaced apart are provided in mixing chamber 14, through the first baffle after refrigerant entrance
The second baffle 16 is reached after 15 drainage, then the drainage through second baffle 16 reaches first baffle 15, so recycles, is in
For ' S ' type motion state by second mixing chamber 14, the first baffle 15 and 16 tilt distribution of the second baffle can
Utmostly to increase flow channel length, increase the time of gas-liquid mixed, improve gas-liquid two-phase mixture homogeneity again, realizes the 5th
