Below with reference to Fig. 1-Fig. 6, the air-conditioning system 100 according to the embodiment of the present invention is described.
According to the air-conditioning system 100 of the embodiment of the present invention, as shown in Figure 1, comprising: compressor 1, pressure servo controller 2, condenser 3, evaporimeter 4, aspirating air pipe 5, outlet pipe 6, first pressure-detecting device 7 and control unit (scheming not shown).
Wherein, pressure servo controller 2 comprises housing 21, space changes assembly 22 and driver 23, cushion space V1 is limited in housing 21, housing 21 is provided with the air inlet c and gas outlet d that are communicated with cushion space V1, space changes assembly 22 and is located in housing 21, driver 23 and space change assembly 22 and are connected to drive space to change assembly 22 action to regulate the size of cushion space V1, and driver 23 is connected with control unit.
With reference to Fig. 1, compressor 1 has exhaust outlet a and air entry b, and aspirating air pipe 5 is connected with air inlet c with exhaust outlet a respectively, and namely aspirating air pipe 5 is connected between compressor 1 and pressure servo controller 2.One end of outlet pipe 6 is connected with gas outlet d, and the other end of outlet pipe 6 is connected with condenser 3, and namely outlet pipe 6 is connected between pressure servo controller 2 and condenser 3, and the two ends of evaporimeter 4 are connected with air entry b with condenser 3 respectively.
In air-conditioning system 100, the flow process of refrigerant is: cold media gas is discharged from exhaust outlet a after being compressed by compressor 1, the cold media gas of discharging is directed in the cushion space V1 of pressure servo controller 2 by aspirating air pipe 5, cold media gas in cushion space V1 flows to condenser 3 from gas outlet d by outlet pipe 6, refrigerant flows to evaporimeter 4 after condensation heat release in condenser 3, refrigerant is evaporation endothermic in evaporimeter 4, thus the air flowing through evaporimeter 4 is freezed, the refrigerant in last evaporimeter 4 flows back to compressor 1 from air entry b again.Thus, refrigerant completes kind of refrigeration cycle in air-conditioning system 100.
First pressure-detecting device 7 is for detecting the pressure of the exhaust outlet a of compressor 1, first pressure-detecting device 7 is connected with control unit, control unit, according to the testing result control and drive system 23 of the first pressure-detecting device 7, changes assembly 22 action to regulate the size of cushion space V1 to drive space.That is, first pressure-detecting device 7 detects the exhaust pressure value of compressor 1, then testing result is passed to control unit, control unit sends instruction according to testing result automatic decision and to the driver 23 of pressure servo controller 2, driver 23 changes assembly 22 action, to adjust the size of cushion space V1 according to this order-driven space.
Here, compressor 1 compresses the refrigerant of rear discharge for high speed, high-pressure gaseous refrigerant, the cold media gas that compressor 1 is discharged flows in the cushion space V1 of pressure servo controller 2 by aspirating air pipe 5, air inlet c successively, because cold media gas enters cushion space V1 by narrow and small aspirating air pipe 5, the volume of the circulation passage of cold media gas increases instantaneously, the pressure of cold media gas is reduced, the corresponding reduction of kinetic energy of cold media gas simultaneously, speed reduces, and the cold media gas after reduction of speed imports condenser 3 by outlet pipe 6 again.Thus, pressure servo controller 2 can reduce the pressure at expulsion of compressor 1, reduces the exhaust velocity of compressor 1.
When the increase of air-conditioning system 100 load, compressor 1 rotating speed increase, compressor 1 pressure at expulsion has and fluctuates largely, and pressure at expulsion fluctuation is converted into the signal of telecommunication by the first pressure-detecting device 7 now in system, then the signal of telecommunication is inputed to control unit.Action is carried out in the signal input that the driver 23 of pressure servo controller 2 sends according to control unit, makes space change assembly 22 action to increase the volume of cushion space V1.When the reduction of air-conditioning system 100 load, compressor 1 rotating speed reduce, control unit controls space by driver 23 again and changes assembly 22 action to reduce the volume of cushion space V1.
That is, by arranging the first pressure-detecting device 7 to coordinate control unit, pressure servo controller 2, can realize increasing cushion space V1 when compressor 1 pressure at expulsion is larger to increase Amplitude of Hypotensive, otherwise then reduce cushion space V1 to reduce Amplitude of Hypotensive.And also achieve the Real-Time Monitoring of compressor 1 pressure at expulsion, establish the servomechanism of pressure oscillation, thus ensure whenever and wherever possible, the stable refrigeration demand meeting user.
Thus, can according to the pressure servo controller 2 of the size adjustment cushion space V1 volume size of compressor 1 pressure at expulsion by arranging, thus make the exhaust pressure value of compressor 1 more steady, suppress the exhaust gas pulses that compressor 1 produces, especially the exhaust gas pulses that compressor 1 produces under bad working environments can be suppressed, the stationarity of pressure in raising system, thus the stable output improving air conditioner refrigerating amount.The inhibitory action of the pressure pulse of pressure servo controller 2 pairs of air-conditioning systems 100, suppresses even to eliminate due to the noise of pulses generation, abnormal sound and covibration.The alleviation of air-conditioning system 100 internal resonance phenomenon, extends the service life of parts, eliminates and gets loose owing to vibrating the interface unit caused; thus reduce the leakage of coolant refrigeration agent; and then the fluorine element balance in maintenance air, Ozonosphere protection, maintains the ecological balance.
And the reactive muffler in traditional air-conditioning system 100, the adjustable range of the pressure at expulsion of pressure servo controller 2 pairs of compressors 1 is more wide in range, accurate, and Exhaust Gas is more mild.Meanwhile, use pressure servo controller 2 step-down noise reduction, air-conditioning system 100 flow losses reduce, thus decrease energy ezpenditure, improve efficiency.
It should be noted that, control unit can be any control device, here concrete restriction is not done, as long as control unit can accept the testing result of the first pressure-detecting device 7, and carry out control and drive system 23 according to this testing result, to control to drive space to change assembly 22 action to regulate cushion space V1.Alternatively, control unit can be only for the independent control of controlled pressure servo controller 2, and control unit also can be the controller run for controlling air-conditioning system 100 complete machine, such as, in examples more of the present invention, air-conditioning system 100 is for vehicle, and control unit is air conditioning for automobiles ECU.In addition, as shown in Figure 1, the first pressure-detecting device 7 can be located on aspirating air pipe 5, and the first pressure-detecting device 7 also can be located at the exhaust outlet a place of compressor 1 or the contiguous air inlet c place of pressure servo controller 2, does not do concrete restriction here.
According to the air-conditioning system 100 of the embodiment of the present invention, by arranging the first pressure-detecting device 7 and pressure servo controller 2, pressure servo controller 2 has the cushion space V1 of the pressure at expulsion for reducing compressor 1, first pressure-detecting device 7 is for the pressure at expulsion of Real-Time Monitoring compressor 1, pressure servo controller 2 regulates the size of cushion space V1 according to the detected value of the first pressure-detecting device 7, thus suppress the pressure at expulsion fluctuation of compressor 1, namely inhibit the exhaust gas pulses of compressor 1, improve system pressure stationarity, and then improve the output stability of air conditioner refrigerating amount.Meanwhile, also inhibits the noise of air-conditioning system 100, abnormal sound and covibration, improve the connection reliability of parts, extend the service life of parts, avoid interface unit and to get loose the leakage of the coolant refrigeration agent caused.And the adjustable range of the pressure at expulsion of pressure servo controller 2 pairs of compressors 1 is wide, flow losses are few, thus reduce energy consumption, raise the efficiency.

That is, the gas pressure before the first pressure-detecting device 7 regulates for detected pressures servo controller 2, the gas pressure after the second pressure-detecting device 8 pairs pressure servo controller 2 regulates carries out Real-Time Monitoring, Real-time Feedback.Testing result is fed back to control unit by the second pressure-detecting device 8, and after control unit calculates, issuing command, to driver 23, makes corresponding actions with controlled pressure servo controller 2 again.
When the second pressure-detecting device 8 detects that the cold media gas pressure of discharging from gas outlet d is more steady, there is not action in the second pressure-detecting device 8.When the second pressure-detecting device 8 detects the cold media gas pressure oscillation of discharging from gas outlet d, fluctuation signal is passed to control unit by the second pressure-detecting device 8, makes from the cold media gas pressure of gas outlet d discharge more steady with the size adjusting cushion space V1 further.
Thus, second pressure-detecting device 8 coordinates the first pressure-detecting device 7 to achieve STOCHASTIC CONTROL to pressure servo controller 2, closed-loop control, form the closed-loop control to pressure oscillation, thus ensure reliability, the real-time of control, improve pressure controlled control accuracy and sensitivity, and then suppress the pressure oscillation of compressor 1 further, keep pressure mild.
