Liquid pipe to compressor liquid-spraying mouth branch road.The operating mode of air conditioner includes very much, mainly includes heating mode, compression
Machine stops working mode, refrigeration mode, defrosting mode and reset mode, wherein hydrojet electric expansion valve is mainly in air-conditioning
It works under the corresponding heating mode of device, plays the role of drop exhaust.The air conditioner heat-production mode course of work is as follows: 1, compressor will
After the cold coal of low-pressure low-temperature gaseous state that gas returning port is returned is compressed into the cold coal of gaseous state of high pressure-temperature, package heat exchange is discharged to by four-way valve
Device；2, high pressure-temperature gaseous coolant is condensed into the liquid refrigerants of high pressure medium temperature after case tube heat exchanger heat release；3, high pressure medium temperature
For liquid refrigerants after main road electric expansion valve reducing pressure by regulating flow, the gas-liquid mixture for becoming low-pressure low-temperature enters finned heat exchanger；

In the case where meeting certain condition, when delivery temperature is very high, hydrojet electric expansion valve is opened, and temperature is higher, hydrojet electricity
The aperture of sub- expansion valve is bigger, on the contrary when delivery temperature is lower, needs to determine hydrojet electric expansion valve according to preset algorithm
Carry out open or shutoff operation, and temperature it is lower and within a preset range when, the aperture of hydrojet electric expansion valve can protect
It holds constant, can prevent hydrojet electric expansion valve from frequently adjusting in this way, to prolong the service life.
It should be noted that there are two types of control models for the aperture of the electric expansion valve of main road, one is working as, delivery temperature is small
When preset temperature, the aperture of electric expansion valve is controlled by the return-air degree of superheat；Another is when delivery temperature is greater than default temperature
When spending, the aperture of electric expansion valve is controlled by delivery temperature.Cause back liquid dangerous in order to avoid there is liquid coolant to enter compressor,
Then the aperture of main road electric expansion valve will be controlled by delivery temperature, can be made aperture control so in the reasonable scope, be made to pass through
The refrigerant that main road electric expansion valve enters finned heat exchanger evaporates in time.Therefore, the control of hydrojet electric expansion valve of the invention
Method makes delivery temperature fall below preset temperature in time hereinafter, i.e. it is swollen to realize main road electronics less than preset temperature for delivery temperature
The aperture of swollen valve is controlled by delivery temperature, effectively reduces back liquid risk.
The hydrojet control method for electronic expansion valve that the present embodiment proposes is obtained when the air conditioner is in open state
The current operating mode of air conditioner then determines whether the operating mode is heating mode, next in the operating mode
When for heating mode, the environment temperature and the corresponding delivery temperature of the air conditioner of the air conditioner are obtained, is finally based on institute
State the aperture of environment temperature, the delivery temperature and preset algorithm adjustment hydrojet electric expansion valve.Pass through environment temperature and row
Temperature degree judges whether that the operation to hydrojet electric expansion valve is needed to control, and determines the big of aperture according to preset algorithm
Small, it is more intelligent to realize hydrojet electronic expansion valve controls, hydrojet electric expansion valve is not adjusted frequently with delivery temperature, to prolong
The service life for having grown hydrojet electric expansion valve makes delivery temperature drop to target temperature range in time, and effectively reduces
Return liquid risk.
The second embodiment of hydrojet control method for electronic expansion valve of the present invention is proposed referring to Fig. 4 based on first embodiment,
In the present embodiment, step S40 includes:
Step S41, the environment temperature be less than or equal to the first default environment temperature and the delivery temperature be greater than or
When equal to the first default delivery temperature, determine whether the hydrojet electric expansion valve is in close state；
In the present embodiment, when environment temperature and delivery temperature meet different conditions, then hydrojet electric expansion valve is pressed
According to different rule operations.
Specifically, when environment temperature is less than or equal to the first default environment temperature and delivery temperature is greater than or equal to first in advance
If when delivery temperature, further determining that the corresponding state of hydrojet electric expansion valve, that is, judge that current hydrojet electric expansion valve is out
Open state or closed state.It should be noted that environment temperature and delivery temperature must simultaneously meet item in the present embodiment
When part, the operation of next step is just carried out.
For example, the first default environment temperature be 10 degrees Celsius, the first default delivery temperature be 105 degrees Celsius, then when
For environment temperature less than or equal to 10 degrees Celsius and when delivery temperature is greater than 105 degrees Celsius, air conditioner just further checks hydrojet electricity
The corresponding state of sub- expansion valve.
Step S42 is based on the environment temperature and return water temperature when the hydrojet electric expansion valve is in close state
Degree determines the corresponding initial opening of the hydrojet electric expansion valve according to the first preset algorithm；
In the present embodiment, the state of hydrojet electric expansion valve is divided to two kinds, and one is open states, and one is close shape
State is less than or equal to the first default environment temperature in environment temperature and delivery temperature is greater than or equal to the first default delivery temperature
When, the state of hydrojet electric expansion valve is open state under normal conditions, and in special circumstances, such as air conditioner is just from other moulds
Formula be switched to heating mode or environment temperature be just reduced to the first default environment temperature or delivery temperature to be just raised to first default
Delivery temperature etc., these in special circumstances, the state of hydrojet electric expansion valve is in off state.
Specifically, when hydrojet electric expansion valve is in close state, return water temperature is further obtained, and according to environment temperature
Degree, return water temperature calculate the corresponding initial opening of hydrojet electric expansion valve.Calculate the formula of initial opening are as follows:
Initial opening=(m* return water temperature-n* environment temperature) * maximum opening ÷ 100
Wherein, m and n is that coefficient can be obtained determines according to actual conditions by analysis of experimental data, such as m can take
0.3-1.2, n can take 1.0-2.0, and certain those skilled in the art need to guarantee (m* return water temperature-n* when taking the value of m and n
Environment temperature) it is greater than 0.
In the present embodiment, setting m is equal to 0.5, n and is equal to 1.5, maximum opening 500, when return water temperature is Celsius equal to 40
Degree, environment temperature are 8 degrees Celsius, then * 500 ÷ 100=40 of initial opening=(0.5*40-1.5*8), then initial opening is
40%.
Step S43 adjusts the aperture of the hydrojet electric expansion valve to the initial opening.
In the present embodiment, when environment temperature is less than or equal to the first default environment temperature and delivery temperature is greater than or equal to
When the first default delivery temperature, if it is determined that hydrojet electric expansion valve is in close state, then is opened hydrojet electric expansion valve,
And the aperture of hydrojet electric expansion valve is opened to initial opening, wherein initial opening is by environment temperature and return water temperature root
It is determined according to preset algorithm.
Further, in one embodiment, step S40 further include: it is default to be less than or equal to first in the environment temperature
When environment temperature and the delivery temperature are greater than or equal to the second default delivery temperature, opening for the hydrojet electric expansion valve is adjusted
It spends to maximum opening.
In the present embodiment, when environment temperature and delivery temperature meet different conditions, then hydrojet electric expansion valve is pressed
According to different rule operations.
Specifically, when environment temperature is less than or equal to the first default environment temperature and is greater than or equal to the second default exhaust temperature
When spending, hydrojet electric expansion valve is opened into maximum opening, i.e., when delivery temperature is very high, air conditioner needs in time will exhaust temperature
Degree lowers, therefore hydrojet electric expansion valve fully opens, with the work of maximum aperture.
For example, the first default environment temperature be 10 degrees Celsius, the second default delivery temperature be 120 degrees Celsius, then when
For environment temperature less than or equal to 10 degrees Celsius and when delivery temperature is greater than 120 degrees Celsius, it is swollen that air conditioner adjusts the hydrojet electronics
The aperture of swollen valve to maximum opening works.
It should be noted that being greater than the second default environment temperature or delivery temperature less than the default exhaust of third in environment temperature
When temperature, hydrojet electric expansion valve does not need work, i.e., under both of these case, air conditioner, which is performed both by, closes hydrojet electric expansion valve
Operation.Second default environment temperature and third preset delivery temperature, are set by the user according to the actual situation.
For example, the second default environment temperature is 12 degrees Celsius, it is 86 degrees Celsius that third, which presets delivery temperature, then works as ring
For border temperature greater than 12 degrees Celsius or when delivery temperature is less than 86 degrees Celsius, air conditioner closes hydrojet electric expansion valve.
It is default to be less than or equal to first in the environment temperature for the hydrojet control method for electronic expansion valve that the present embodiment proposes
When environment temperature and the delivery temperature are greater than or equal to the first default delivery temperature, whether the hydrojet electric expansion valve is determined
It is in close state, then when the hydrojet electric expansion valve is in close state, is based on the environment temperature and return water
Temperature determines the corresponding initial opening of the hydrojet electric expansion valve according to the first preset algorithm, next adjusts the hydrojet electricity
The aperture of sub- expansion valve is to the initial opening.Judge whether to need to hydrojet electronic expansion by environment temperature and delivery temperature
The operation of valve is controlled, and the size of aperture is determined according to preset algorithm, and it is more intelligent to realize hydrojet electronic expansion valve controls
Change, does not adjust hydrojet electric expansion valve frequently with delivery temperature, to extend the service life of hydrojet electric expansion valve, make to arrange
Temperature degree drops to target temperature range in time, and effectively reduces back liquid risk.
The 3rd embodiment of hydrojet control method for electronic expansion valve of the present invention is proposed referring to Fig. 5 based on second embodiment,
In the present embodiment, step S40 includes:
Step S44 is less than or equal to the first default environment temperature and the delivery temperature first in the environment temperature
When in preset temperature range, determine whether the hydrojet electric expansion valve is in close state；
Step S45 obtains the hydrojet electric expansion valve when the hydrojet electric expansion valve is not off
Current aperture；
In the present embodiment, when environment temperature and delivery temperature meet different conditions, then hydrojet electric expansion valve is pressed
According to different rule operations.
Specifically, when environment temperature is less than or equal to the first default environment temperature and delivery temperature in the first preset temperature model
When enclosing interior, the corresponding state of hydrojet electric expansion valve is further determined that.It should be noted that in the present embodiment environment temperature with
When delivery temperature must simultaneously meet condition, the operation of next step is just carried out.
For example, the first default environment temperature is 10 degrees Celsius, the first 105-110 degrees Celsius of preset temperature range, then
When environment temperature is less than or equal to 10 degrees Celsius and delivery temperature is between 105-110 degrees Celsius, air conditioner is further checked
The corresponding state of hydrojet electric expansion valve.
Further, when hydrojet electric expansion valve is in non-closed state, i.e., hydrojet electric expansion valve is in opening state
State, air conditioner further obtain the current aperture of hydrojet electric expansion valve.It should be noted that the first preset temperature range is big
In the first default delivery temperature, therefore when delivery temperature is in the first preset temperature range, need to further increase hydrojet
The aperture of electric expansion valve.
It is corresponding to update the hydrojet electric expansion valve based on the current aperture and the second preset algorithm by step S46
First aperture；
In the present embodiment, because the first preset temperature range is greater than the first default delivery temperature, therefore when exhaust temperature
When degree is in the first preset temperature range, need to further increase the aperture of hydrojet electric expansion valve, according to current aperture and
Second preset algorithm can determine the first aperture.
Specifically, step S46 further include: be based on the current aperture and the first default step at interval of the first preset duration
First aperture is updated into value.
In the present embodiment, it when delivery temperature is in the first preset temperature range, at interval of preset duration, is opened currently
Degree increases by the first default step value as the first aperture.For example, current aperture is 100, and preset duration 8s, the first default stepping
Value is 5, then by the first aperture of 8s after first time updates, the first aperture=100+5=105.
Step S47 adjusts the aperture of the hydrojet electric expansion valve based on first aperture.
In the present embodiment, when delivery temperature is in the first preset temperature range, it will be updated one at interval of preset duration
Secondary first aperture calculates a new opening value, then is opened into hydrojet electric expansion valve at interval of preset duration air conditioner
New opening value.
It is default to be less than or equal to first in the environment temperature for the hydrojet control method for electronic expansion valve that the present embodiment proposes
Environment temperature and when the delivery temperature is in the first preset temperature range, determines whether the hydrojet electric expansion valve is in pass
Closed state obtains the current of the hydrojet electric expansion valve then when the hydrojet electric expansion valve is not off
Next aperture updates the hydrojet electric expansion valve corresponding first based on the current aperture and the second preset algorithm and opens
Degree, finally adjusts the aperture of the hydrojet electric expansion valve based on first aperture.By at interval of the first preset duration root
The first aperture is updated according to current aperture and the first default step value, it is more intelligent to realize hydrojet electronic expansion valve controls, no
Hydrojet electric expansion valve is frequently adjusted with delivery temperature, to extend the service life of hydrojet electric expansion valve, and effectively
Ground reduces back liquid risk.
