Fig. 2 shows the air conditioning system of the present invention；And
Fig. 3 shows the flow chart of the control method of the air conditioning system of the present invention.
Specific embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Below with reference to the accompanying drawings and in conjunction with the embodiments describing the present invention in detail.
It is shown in Figure 2, the present invention on the basis of existing technology, in double-cylinder variable-capacity compressor lower cylinder air entry to gas
Liquid/gas separator import increase discharge opeing bypass line connection all the way, the discharge opeing bypass line mainly includes capillary tube, the second electromagnetic valve
72, and increase high pressure sensor 100 to detect condensation temperature T in double-cylinder variable-capacity compressor exhaust sideIt is high, at lower cylinder air entry
Increase temperature sensor 90 as detection tool detection lower cylinder air entry temperature TUnder.Discharge opeing bypass pipe is opened under specific circumstances
Second electromagnetic valve 72 on road, to carry out the action of pressure release and discharge opeing.When lower cylinder air entry is in hydrops state, by automatic
Detection, can drain into gas-liquid separator compressor lower cylinder to the liquid refrigerants of the connecting tube between the first electromagnetic valve 71.In list
When cylinder operation switches to twin-tub and runs, bypassed the high pressure refrigerant pressure release of lower cylinder suction side to gas-liquid separator by discharge opeing,
Make single cylinder run successful switch to run to twin-tub, the stability of system when improving switchover operation.
Shown in Figure 2, air conditioning system of the present invention includes double-cylinder variable-capacity compressor 30 and gas-liquid separator, twin-tub transfiguration pressure
Contracting machine 30 draws three tunnels：Upper cylinder air entry, lower cylinder air entry and air vent.Double-cylinder variable-capacity compressor 30, the first heat exchange
Device 10, orifice union 40 and second heat exchanger 20 connect into loop.Air conditioning system also includes cross valve 60, the first electromagnetic valve
71st, check valve 50.First Heat Exchanger 10 connects double-cylinder variable-capacity compressor 30 with the second heat exchanger 20 by the selectivity of cross valve 60,
The one end of first electromagnetic valve 71 connects the air vent of double-cylinder variable-capacity compressor 30, and the other end connects respectively check valve 50 and lower cylinder is inhaled
QI KOU；One end of check valve 50 is connected to the pipeline that the first electromagnetic valve 71 leads to lower cylinder air entry, and the other end accesses gas-liquid point
From device inner chamber, the permission flow direction of check valve 50 is from gas-liquid separator to lower cylinder air entry.Invention increases all the way second
The branch road of electromagnetic valve 72 and capillary tube composition connected in series, is connected to the pipeline and gas-liquid point of compressor lower cylinder air entry
Between the pipeline of device gas-liquid separator import.
The effect of capillary tube in discharge opeing bypass circulation is the flow for controlling discharge opeing.Crossing thick too short capillary flow rate can mistake
Greatly, lower cylinder pressure drop is caused, insufficient pressure can be such that single cylinder operation continues, and change to twin-tub operation；It is meticulous long
Capillary flow rate can be too small, cause drain age velocity excessively slow, discharge opeing action can not be completed within the formulation time；So discharge opeing bypass
Loop needs a moderate capillary tube.
Shown in Figure 3, the control method of the air conditioning system of the present invention includes：

Between after close, with reach interval discharge opeing effect.
(2) when compressor runs in single cylinder, and when having demand to switch to twin-tub operation, the second electromagnetic valve opens the ts times
After turn off the first electromagnetic valve, the second closed electromagnetic valve after the first closed electromagnetic valve t4 times, to reach pressure release effect.
(3) the ts times and outdoor environment because the hydrops situation of different outdoor environment temperature TW is different, in step (2)
Temperature is related, is exemplified below：(A, B are preset temperature constant, can be determined through experiment.)
A) when TW >=A DEG C, ts=t5；
B) as B DEG C≤TW ＜ A DEG C, ts=t6；
C) as TW ＜ B DEG C, ts=t7.(above t1, t2, t3, t4, t5, t6, t7 are Preset Time, can be true through experiment
It is fixed.)
The present invention be using with vapour liquid separator twin-tub or twin-tub more than frequency-changeable compressor combine transfiguration technology come
Expand the range of accommodation of cooling system/heating capacity.The bypass branch effect of the second electromagnetic valve and capillary tube composition is mainly：When
When first electromagnetic valve needs to close, the second electromagnetic valve is opened the pressure of pipeline between lower cylinder air entry and the first electromagnetic valve
Drop to it is consistent with low pressure, to ensure that compressor switches to rapidly twin-tub after the first closed electromagnetic valve.When unit is transported in single cylinder
When row, by the temperature of the pipeline temperature detector detection of air entry under compressor and the high pressure temperature of high pressure sensor detection
Lower air entry whether hydrops is may determine that, the second electromagnetic valve is just driven for a period of time when hydrops is determined, can play prevents
There is the effect of liquid hammer when switching twin-tub after compressor single cylinder longtime running.
The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to, for the skill of this area
For art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repair
