Specific embodiment
In order to keep the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with drawings and examples to this hair
It is bright to be described in detail.It should be appreciated that following specific embodiments only to explain the present invention, do not constitute limit to the present invention
System.
As shown in Figure 1, air conditioner proposed by the present invention include compressor 1, oil device 2, four-way valve 3, outdoor heat exchanger 4,
Controller radiating module 5, outdoor throttle part 6, indoor throttle part 7, indoor heat exchanger 8, setting are changed in four-way valve and interior
A branch 9 and gas-liquid separator 11 between hot device between indoor throttle part and controller radiating module.Branch 9
It is equipped with tonifying Qi throttle part 10.
Controller radiating module 5 is mounted on behind electric controller, passes through the system circulation low temperature in copper pipe in radiating module
Refrigerant takes away electric controller heat.Controller radiating module is equipped with temperature sensor.
For air-conditioner set in normal course of operation, master control obtains an electric controller temperature every a control detection cycle.
If detecting, electric controller temperature is greater than environment temperature, is in close state tonifying Qi throttle part 10, refrigerant is in system at this time
The flow direction of heating condition is 1 → 2 → 3 → 8 → 7 → 5 → 6 → 4 → 3 → 11 → 1；If detecting, electric controller temperature is less than environment temperature
Degree, then make tonifying Qi throttle part 10 in the open state, at this time main flow direction of the refrigerant inside system be 1 → 2 → 3 → 8 → 7 →
5 → 6 → 4 → 3 → 11 → 1, flow to for improving the refrigerant of cooling controller temperature as 1 → 2 → 3 → 10 → 5 → 6 → 4 → 3 →
11→1。
When coolant quantity is less in systems, the refrigerant of high temperature and pressure is substantially completely cold after exchanging heat in heat exchanger 8 indoors
The liquid for medium temperature and medium pressure is coagulated, coolant quantity is fewer, then pressure is lower.After controller radiating module 5, because of evaporating pressure
Reduction, refrigerant can evaporate rapidly, and absorbing a large amount of heat causes controller radiating module temperature relatively low, will lead to control when serious
Device radiating module condensation processed.
In technical solution proposed by the present invention, after detecting that electric controller temperature is less than environment temperature, by tonifying Qi throttle
Part 10 is opened, and it is direct without indoor heat exchanger that the refrigerant vapour for the high temperature and pressure being discharged at this time from compressor understands some
Controller radiating module 5 is entered, at this time the refrigerant vapour of high temperature and pressure and the medium temperature and medium pressure by indoor throttle part 7
Refrigerant liquid is thoroughly mixed, and is entered controller radiating module 5 after improving temperature, while improving the evaporating pressure of refrigerant, is protected
It demonstrate,proves refrigerant evaporation capacity in controller radiating module to reduce, most of heat will not be taken away.
Fig. 2 is the flow chart of first embodiment of the invention.Air conditioner (heating) in normal course of operation, master control is every one
A control detection cycle Qs obtains an electric controller temperature.If detecting electric controller temperature > environment temperature, tonifying Qi is made to throttle
Component 10 is in close state, while opening the aperture of big outdoor throttle part 6 to a aperture.If detecting electric controller temperature <
Environment temperature then makes tonifying Qi throttle part 10 in the open state, and the aperture of tonifying Qi throttle part is initial opening n pls.If
It detects that electric controller temperature is equal with environment temperature, then keeps original flow of outdoor throttle part 6 and tonifying Qi throttle part 10
It is constant.
After adjustment, continue to monitor.If detecting electric controller temperature > environment temperature, tonifying Qi throttle part 10 is kept to be in
Closed state, while the aperture of big outdoor throttle part 6 is opened to m aperture.If detecting electric controller temperature < environment temperature,
Keep tonifying Qi throttle part 10 in the open state, the aperture of tonifying Qi throttle part is b pls, b=n+c.In the above adjustment process
In, if detecting, electric controller temperature is equal to environment temperature, and outdoor throttle part 6 and the original of tonifying Qi throttle part 10 is kept to open
It spends constant.
Fig. 3 is the flow chart that the present invention second implements stream.Electric controller temprature control method includes:
Step 1. obtains electric controller temperature and outdoor environment temperature, and air-conditioner set (heating) in normal course of operation, master control is every
An electric controller temperature is obtained every a control detection cycle Qs；
Step 2. judges whether electric controller temperature is greater than outdoor environment temperature, such as larger than, then closes tonifying Qi throttle part 10, simultaneously
The aperture of outdoor throttle part 6 is tuned up to a aperture；Such as less than, then the aperture of tonifying Qi throttle part 10 is opened to initial opening
N, while the aperture of outdoor throttle part is reduced to aperture d from a, wherein a > d > initial opening；Such as it is equal to, then maintains tonifying Qi
Original flow of throttle part 6 and outdoor throttle part 10 is constant.
After step 3. adjustment, continue to monitor.Judge whether electric controller temperature is greater than outdoor environment temperature, such as larger than, then protects
It holds tonifying Qi throttle part to be in close state, while the aperture of outdoor throttle part 6 being tuned up from a to m aperture；Such as less than, then
The aperture of tonifying Qi throttle part 10 is tuned up from n to b aperture, meanwhile, the aperture of outdoor throttle part is turned down to q aperture,
Middle q=a-c.
In the above adjustment process, if detect electric controller temperature be equal to environment temperature, keep outdoor throttle part 6 and
Original aperture of tonifying Qi throttle part 10 is constant.
Technical solution proposed by the present invention by the way that the refrigerant of the refrigerant of high temperature and pressure and medium temperature and medium pressure is mutually mixed so that
Refrigerant temperature into controller radiating module increases, and the local pressure in lifting controller radiating module avoids refrigerant very fast
Evaporation avoid electric controller condensation to realize the stability contorting of electric controller temperature.
