Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can be mutually combined.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
When the conventional throttling arrangement of existing air conditioner is capillary, generally single capillary, once it is determined that the length of capillary
And caliber, then there was only a kind of throttling degree.But system is in the process of running, it is desirable to reach best refrigeration or heating effect, its
The throttling degree needed is different.It is right the continuous improvement required with consumer in comfortableness air conditioner, hot environment simultaneously under
The demand of refrigerating capacity is a more and more important parameter, and the application designs a kind of novel throttling device of air conditioner, with general sky
Adjust device different, take the structure design of uniqueness, cooling and warming ability can not only be improved, the effect of rapid warm raising temperature drop is realized, together
When can reduce noise, concrete structure is as follows：
Shown in Fig. 1, the throttling arrangement of embodiment one includes the first pipeline 40 and the second pipeline 50, the first throttle valve being arranged in parallel
10th, second throttle 20 and control valve 30.Wherein, first throttle valve 10 is arranged on the first pipeline 40, second throttle
20 are arranged on the second pipeline 50, and control valve 30 is arranged on the first pipeline 40 and is arranged in series with first throttle valve 10, control
Valve 30 processed is turned on or off according to the pressure at two ends difference of the first pipeline 40.
Using the technical scheme of the present embodiment, control valve 30 is opened or closed according to the pressure difference value at the two ends of the first pipeline 40.
Said structure can realize that control valve 30 is opened when the pressure differential before and after throttling arrangement is excessive, increase cold medium flux；Work as throttling
When pressure differential before and after device is too small, control valve 30 is closed, and reduces cold medium flux.The above-mentioned control to cold medium flux is enabled to
Air-conditioning system can more flexibly adapt to the various operating modes of air conditioner, so as to improve the refrigeration performance that heats of air conditioner, especially
Refrigeration in high temperature environments.It can also reduce system noise simultaneously.Therefore the technical scheme of the present embodiment solves existing
The problem of throttling arrangement in technology can not meet the complex working condition of air conditioner.
Further, second throttle 20 is not only limited in a first throttle valve 10 in parallel, can be second for need of work
Multiple first throttle valves 10 in parallel on choke valve 20, and then realize more flexible control cold medium flux.While control valve 30
The number set can be determined according to actual needs.
It should be noted that in the technical scheme of embodiment one, because first throttle valve 10 and second throttle 20 are parallel connection
Set, therefore the pressure at the two ends of first throttle valve 10 and control valve 30, being compared with the pressure at the two ends of second throttle 20 is
The same, therefore the pressure at selection measurement the first pipeline 40 two ends is only needed in measurement pressure, or measure the second pipeline 50
The pressure at two ends.
In the technical scheme of embodiment one, control valve 30 is magnetic valve, and throttling arrangement also includes pressure tester and control device.
Wherein, pressure tester is used for the pressure differential for obtaining the two ends of the first pipeline 40, and control device connects with pressure tester and control valve 30
Connect, pressure differential duty control solenoid valve that control device is obtained by pressure tester is turned on or off.Control device is by judging
The pressure differential of first pipeline 40 and then judge whether needs increase cold medium flux or reduces cold medium flux, from control control valve 30
Opening and closing.
Specifically, pressure tester is temperature-sensitive bag.Temperature-sensitive bag is common components in air conditioner, and its effect is to be converted into temperature information
Pressure information.Therefore it is that the monitoring for pressure can be achieved using temperature-sensitive bag, temperature-sensitive bag is conventional structure, be will not be repeated here.
As shown in figure 1, in the technical scheme of embodiment one, throttling arrangement also includes the 3rd pipeline 70 and the 4th pipeline 80.The
The first end of one pipeline 40 and the first end of the second pipeline 50 are connected with the 3rd pipeline 70, the second end of the first pipeline 40 and
Second end of the second pipeline 50 is connected with the 4th pipeline 80.Refrigerant is flowed into from the 3rd pipeline 70, through first throttle valve 10, or
After person's first throttle valve 10 and second throttle 20, flowed out from the 4th pipeline 80.Or flowed into from the 4th pipeline 80 and from
Three pipelines 70 flow out.The specific mobility status of refrigerant is determined according to the actual cooling and warming situation of air-conditioning system.
Preferably, in the technical scheme of embodiment one, first throttle valve 10 and second throttle 20 are capillary.Capillary
Pipe cost is low, while working stability.
As shown in Fig. 2 being according to the difference of the embodiment two and embodiment one of the throttling arrangement of the application, pressure tester is pressure
Power table 60.Pressure gauge can more accurately monitor the pressure at the two ends of the first pipeline 40 or the second pipeline 50, and then make cold
Matchmaker's flow is more suitable for system, so that the cooling and warming ability of system is improved, while can reduce system noise again.
Specifically, in the technical scheme of embodiment two, pressure gauge 60 is two, and two pressure gauges 60 are separately positioned on first
The two ends intersection of the pipeline 50 of pipeline 40 and second.
It is according to the difference of the throttling arrangement embodiment three and embodiment one and embodiment two of the application, control valve 30 is mechanical valve,
Namely without setting pressure measuring system in throttling arrangement.Mechanical valve can be selected using the stop valve by Stress control, work as mechanical valve
Pressure at two ends when reaching certain numerical value mechanical valve open, otherwise close.Mechanical valve can be adjusted according to system needs simultaneously
Preset pressure.Above-mentioned valve is prior art, and operation principle is repeated no more.
Present invention also provides a kind of air conditioner, as shown in Figure 3 and Figure 4, shell is included according to the embodiment of the air conditioner of the application
Body and the compressor 100 being arranged in housing, condenser 200, evaporator 300 and throttling arrangement 400, throttling arrangement 400
For above-mentioned throttling arrangement.Compressor 100, condenser 200, evaporator 300 and throttling arrangement 400 constitute refrigeration system,
Simultaneously according to the different operating modes of the cooling and warming of air conditioner, the direction of refrigerant flowing is also differed.Specifically, Fig. 3 is refrigeration system
The flow direction of refrigerant in refrigeration, the flow direction of refrigerant when Fig. 4 heats for refrigeration system, the change of above-mentioned refrigerant flow direction is by four-way
What valve was realized.
As shown in Figure 3 and Figure 4, in the technical scheme of the present embodiment, throttling arrangement 400 is arranged on evaporator 300 and condensation
Between device 200.When refrigerant flows through throttling arrangement 400, flow is adjusted.
