Although it will be appreciated to those of skill in the art that foregoing description combination multi-gang air-conditioner carry out, this
Kind describing mode is used merely to illustrate the technical principle of the utility model, is not intended to limit the scope of protection of the utility model,
On the premise of without departing from the utility model principle, those skilled in the art can make it any type of adjustment, so as to
Adapt to more specifical application scenarios.Quantity such as indoor unit can also be any, be arranged at compressor 14, the oil of outdoor unit
Separator 15 can also be arranged at indoor unit etc..
With further reference to Fig. 1, specifically, main system pipeline includes the first main line 131 and the second main line 132, the
One main line 131 and the second main line 132 respectively constitute the outdoor pusher side of main system pipeline and indoor pusher side.Refrigerant adjusts tank 21
Bottom offer first port 211 and second port 212, top offers the 3rd port 213 and the 4th port 214.Refrigerant
Pipeline is adjusted to further comprise being provided with the adjusting main line 311 of first switch valve 314, be provided with the of the first check valve 315
One branch line 312 and the second branched pipe road 313 for being provided with the second check valve 316.In addition, except refrigerant adjust pipeline it
Outside, refrigerant regulating system further includes the pressure piping 32 for being provided with second switch valve 321 and is provided with the 3rd switch valve 331
Relief line 33.Preferably, first switch valve 314,321 and the 3rd switch valve 331 of second switch valve are all solenoid valves.Certainly,
This setup is not unique, and switch valve can also be pneumatic operated valve etc..
Wherein, the first main line 131 connects outdoor heat exchanger 11 with first port 211, and the second main line 132 is by
Two-port netwerk 212 is connected with indoor heat converter 12.Adjust main line 311 and be connected to the bottom that refrigerant adjusts tank 21, the first branch
Pipeline 312 is connected between adjusting 311 and first main line 131 of main line, and second branched pipe road 313 is connected to adjusting main line
311 and second between main line 132, and the first check valve 315 and the second check valve 316 only allow refrigerant to adjust tank from refrigerant
21 to main system tube runs, that is, are flowed respectively to the first main line 131 and the second main line 132.Pressure piping 32 will
3rd port 213 is connected to the oil eliminator 15 positioned at 14 exhaust side of compressor, and the 4th port 214 is connected to by relief line 33
Positioned at the gas-liquid separator 16 of 14 suction side of compressor.
The advantages of above-mentioned set-up mode, is：By when coolant quantity is in different conditions, opening different switch valves, just
It can realize the adjusting of coolant quantity in multi-gang air-conditioner, lift the refrigeration effect of air-conditioning.With the refrigeration work mould of multi-gang air-conditioner
Exemplified by formula, when the coolant quantity for the machine of getting in is not more than optimal refrigerant amount, multi-gang air-conditioner shows as the cold of the machine of getting in
Matchmaker measures deficiency, and the indoor unit degree of superheat is larger, and expansion valve opening is larger, and refrigeration effect is poor.Open at this time first switch valve 314 with
Second switch valve 321, closes the 3rd switch valve 331, and the liquid refrigerants of the lower section of tank 21 is adjusted by adjusting main line positioned at refrigerant
311 and second branched pipe road 313 enter the second main line 132, and then machine is got in, to solve the problems, such as that coolant quantity is insufficient.
The high-pressure gaseous refrigerant that compressor 14 exports then can be passed through supercharging by the unlatching of second switch valve 321 after oil eliminator 15
Pipeline 32 enters refrigerant and adjusts tank 21, then lifts the pressure in refrigerant adjusting tank 21, makes the liquid that refrigerant is adjusted in tank 21 cold
Matchmaker more quickly gets in machine, the quick coolant quantity for increasing indoor unit, improves the refrigeration effect of multi-gang air-conditioner.Into entering the room
It is interior and coolant quantity when being more than optimal refrigerant amount, multi-gang air-conditioner shows as system pressure rise, power rise.Make the 3rd at this time
Switch valve 331 is opened, and first switch valve 314 and second switch valve 321 are closed, and the gaseous coolant above tank 21 is adjusted positioned at refrigerant
Returned to by relief line 33 in gas-liquid separator 16, so can by 11 condensed liquid refrigerants of outdoor heat exchanger
More refrigerants that are stored in are adjusted in tank 21, to solve the problems, such as that indoor-unit cooling-medium amount is excessive.Further, second switch valve
321 also reside in the advantages of unlatching：The gaseous state that 14 air entry of delivery temperature and make up compressor of compressor 14 can be reduced is cold
Matchmaker measures.In addition, the setting of the first check valve 315 and the second check valve 316, additionally it is possible to avoid the reflux of refrigerant or letting out for pipeline
Pressure.
It should be noted that why refrigerant is adjusted pipeline after main line 311 is adjusted is divided into the first branch line
312 and second branched pipe road 313, it is especially switching refrigeration and heating operating mode because in air-conditioning switching working mode
When, the refrigerant flow direction in main system pipeline is on the contrary, adjusting two branch lines of main line 311 at this time can correspond to respectively
It is cold in refrigeration work pattern to correspond to multi-gang air-conditioner with heating operating mode, i.e. second branched pipe 313 for refrigeration work pattern
Matchmaker is adjusted, and the first branch line 312 corresponds to refrigerant of the multi-gang air-conditioner when heating operating mode and adjusts.
The utility model additionally provides a kind of air conditioner, which includes outdoor unit and multiple indoor units (such as four),
And the main system pipeline for connecting outdoor unit with indoor unit, wherein, foregoing refrigerant is provided with main system pipeline and adjusts system
System.
In conclusion the refrigerant regulating system of the utility model includes, refrigerant adjusts tank 21, refrigerant adjusts pipeline, pressure inlet
Road 32 and relief line 33.Wherein refrigerant adjust pipeline have further comprise adjust main line 311, the first branch line 312 with
And second branched pipe road 313.Tank is adjusted by refrigerant and refrigerant adjusts the setting of pipeline, can be in multi-gang air-conditioner refrigerating operaton
When, coolant quantity is adjusted by refrigerant regulating system, ensures the optimal refrigeration effect of air-conditioning, improves the stable of air-conditioning
Property, solve the problems, such as that multi-gang air-conditioner operational effect is poor caused by coolant charging amount is there are error, substantially improve user
Experience.
It is described although above-mentioned preferred embodiment is the refrigeration work pattern for combining multi-gang air-conditioner, this
The application scenarios of utility model are not unique, and on the premise of without departing from the utility model principle, those skilled in the art may be used also
The utility model to be applied to other operating modes of multi-gang air-conditioner, such as heating mode, dehumidification mode.
So far, have been combined preferred embodiment shown in the drawings and describe the technical solution of the utility model, still, this
Field technology personnel are it is easily understood that the scope of protection of the utility model is expressly not limited to these embodiments.
Without departing from the utility model principle on the premise of, those skilled in the art can make correlation technique feature equivalent change
