Description
Technical field
The present invention relates to compressor, be specifically related to control the apparatus and method of operation of reciprocating compressor.
Background technique
Usually, reciprocal compressor does not adopt and is used for being transformed into rotatablely moving straight-line crankshaft, so it has higher compression efficiency than common compressor.
When reciprocal compressor is applied to refrigerator or air-conditioning, in order to control refrigerating capacity, can change the compressibility of this reciprocal compressor by the stroke voltage that change inputs to reciprocal compressor.
To explain the reciprocal compressor of prior art according to Fig. 1 below.
Shown in Fig. 1 be according to prior art, be used to control the structure Block Diagram of the device of operation of reciprocating compressor.
As shown in Figure 1, the prior-art devices that is used to control operation of reciprocating compressor comprises: voltage detector 14, and it is used to detect the voltage that imposes on this reciprocal compressor 13 when the stroke of reciprocal compressor 13 changes; Current detector 12, it is used to detect the electric current that imposes on this reciprocal compressor 13 when the stroke of reciprocal compressor 13 changes; Microcomputer 15, it calculates stroke based on voltage detector 14 detected magnitude of voltage and current detector 12 detected current values, stroke and the stroke reference value that calculates is compared, and produce changeover control signal according to this comparative result; And power pack 11, its changeover control signal that is produced according to microcomputer 15, control the ON/OFF of the Ac that offers reciprocal compressor 13, thereby stroke voltage is offered this reciprocal compressor 13 by utilizing inner TRIAC Tr1.
This reciprocal compressor 13 receives the stroke voltage that the stroke reference value that sets according to the user offers the motor internal (not shown), changes its stroke, and allows the internal piston (not shown) do reciprocatory motion.
Below explanation is used to control the operation of the prior-art devices of operation of reciprocating compressor.
At first, when the stroke reference value of setting according to the user offered motor internal with voltage, reciprocal compressor 13 changed its stroke and allows piston do reciprocatory motion.Here, stroke represents that the piston of reciprocal compressor 13 carries out the distance of reciprocatory motion along it.
By the changeover control signal of slave microcomputer 15 outputs, prolong the lasting on time of the TRIAC Trl of power pack 11, and therefore Ac is offered reciprocal compressor 13 to drive this reciprocal compressor 13.At this moment, voltage detector 14 and current detector 12 detect the voltage and current that imposes on reciprocal compressor 13 respectively, and detected voltage and current value is exported to microcomputer 15.
Yet, if the stroke value that calculates is greater than stroke reference value, then microcomputer 15 to power pack 11 output changeover control signals shortening the lasting on time of TRIAC Trl, thereby reduce to offer the stroke voltage of reciprocal compressor 13.
The single capacitor 16 that is in series with the motor internal of reciprocal compressor 13 has compensated the inductance of coil winding in the motor internal.
Simultaneously, in the prior-art devices that is used for controlling operation of reciprocating compressor, when by TRIAC Tr1 voltage being imposed on the motor of compressor 13, just produced noise for the stroke of controlling compressor.In order to eliminate this noise, just need relay 17 shown in Figure 2 and the motor of forming by main coil 19 and secondary coil 20 18.
For instance, according to the variation of the operation load of voltage change that inputs to compressor and compressor, 17 on relay is selected main coil 19 or is not only selected main coil 19 but also select secondary coil 20, thereby changes the electric capacity of motor 18.For example, if input voltage increases or the operation load of compressor greater than predefined with reference to load (that is, under the situation of overload), then microcomputer 15 control relays 17 allow its selection main coil 19, to reduce the back electromotive force constant of motor 18.
Simultaneously, if input to that the voltage of compressor reduces or the operation load of compressor less than predefined with reference to load (promptly, owing under the situation of load), then microcomputer 15 control relays 17 allow it not only select main coil 19 but also select secondary coil 20, to increase the back electromotive force constant of motor 18.Here, according to the variation of voltage change that inputs to compressor and compressor operation load, the operator scheme of this compressor is changed over electric source modes (power mode) or safe mode.This electric source modes refers to the pattern that motor is therein only operated by main coil, and this safe mode refers to the pattern that motor had therein both been operated by secondary coil by main coil.
The winding times N of the coil winding in the motor 18 of reciprocal compressor is directly proportional with the back electromotive force constant of this motor, thereby, when certain voltage was imposed on compressor, the winding number of times of the stroke of this compressor and coil was inversely proportional to, and can be expressed by equation as follows (1):
Therefore, come control relay 17, thereby the electric capacity that changes motor is to control this motor according to the variation of the operation load of electric power variation that is applied to compressor and compressor.
Yet, for according to prior art, be used to control the device of operation of reciprocating compressor, when compressor is in electric source modes or is in safe mode, only electric power is imposed on the motor 18 of compressor, thereby caused the compressor operation problem of unstable by a capacitor that is connected to motor 18.For example, change over electric source modes or when electric source modes changed over safe mode, therefore the winding number of times that has changed motor coil had changed the inductance of motor coil from safe mode when the operator scheme of compressor.But because compressor only passes through a capacitor operation, therefore, the fluctuation of service of this compressor.
The U.S. Patent No. 6,644,943 that on November 11st, 2003 announced also discloses reciprocal compressor.

As shown in Figure 3, the device that is used to control compressor operation comprises: the controller (not shown), and its operation load according to compressor produces the control signal that is used to select the compressor operation pattern; First relay 17, it is electrically connected to the motor of being made up of main coil 19 and secondary coil 20 18, and selects the control signal of compressor operation pattern only to select main coil 19 or not only select main coil 19 but also select secondary coil 20 according to being used to; First capacitor 16 and second capacitor 21 that is connected to first relay 17 parallel with one another; And second relay 22, it is connected to first capacitor 16, and according to the control signal that is used to select the compressor operation pattern, electric power is imposed on the power cut that first capacitor 16 maybe will impose on first capacitor 16.Here, the microcomputer 15 of Fig. 1 can be carried out the function of this controller.

The winding number of times of main coil 19 and the winding number of times of secondary coil 20 can be constructed identical or differently.The electric capacity of first capacitor 16 and second capacitor 21 can preferably be determined based on the inductance value of motor coil.
Explain the method that is used to control compressor operation according to of the present invention below in conjunction with Fig. 4.
Fig. 4 is according to the present invention, is used to control the flow chart of the method for compressor operation.
At first, controller is operated this compressor according to the operation load of compressor.For example, if compressor is installed in the air-conditioning, then this compressor is based on predefined temperature required operate with room temperature (the step S11) of user.In the case, controller is based on predefined temperature required with room temperature and the operation change of compressor is become electric source modes or safe mode.That is to say, if input to that the voltage of compressor increases or the operation load of compressor greater than predefined during with reference to load, then controller preferably changes over electric source modes with the operator scheme of compressor.
After this, if the operation load of compressor is greater than the reference load, when the operation load according to compressor will change over electric source modes to the operator scheme of compressor, controller produces first control signal that is used for the operator scheme of compressor is changed over electric source modes, and this first control signal is exported to first relay 17 and second relay 22 (step S12).In the case, can adopt multiple different conversion equipment to replace relay.
Explain the operation of the device that when its operator scheme is changed over electric source modes, is used to control compressor operation below in conjunction with Fig. 5.
Shown in Fig. 5 is the operational block figure that is used to control the device of compressor operation according to the present invention, when the operator scheme of compressor is changed over electric source modes.
At first, according to first control signal of slave controller output, 17 on first relay is selected main coil 19.At this moment, electric power only flows through main coil 19, and in the case, because electric power only flows, has therefore reduced the back electromotive force constant (step S13) of motor in main coil 19.
According to first control signal of controller, second relay 22 imposes on first capacitor 16 with electric power, thereby allows electric power impose on main coil 19 by first capacitor 16 and second capacitor 21.In other words, when only having selected main coil 19, controller with first capacitor 16 and 21 parallel connections of second capacitor to increase electric capacity and to carry out the LC resonance operation.
Simultaneously, if the operation load of compressor is less than the reference load, when the operation load according to compressor will change over safe mode to the operator scheme of compressor, controller produces second control signal that is used for the operator scheme of compressor is changed over safe mode, and this second control signal is exported to first relay 17 and second relay 22.Be used to control the operation of the device of compressor operation when explaining that below in conjunction with Fig. 6 operator scheme with compressor changes over safe mode.
According to second control signal of slave controller output, first relay 17 is selected main coil 19 and secondary coil 20.At this moment, power flows main coil 19 and secondary coil 20, and, because electric power flows, therefore increased the back electromotive force constant (step S15) of motor in main coil 19 and secondary coil 20.
According to second control signal of controller, second relay 22 disconnects first capacitor 16 will imposing on the power cut of first capacitor 16, thereby allows electric power only impose on main coil 19 and secondary coil 20 (step S16) by second capacitor 21.That is to say that when having selected main coil 19 and secondary coil 20, controller will impose on the power cut of first capacitor 16, to reduce electric capacity and to carry out the LC resonance operation.
Therefore therefore, when the inductance value of motor coil changed along with the operation load of compressor, the resonating capacitor that is connected to this motor changed, and had changed the capacitance of resonating capacitor, thus Driven Compressor stably.
As previously described, the device that is used for controlling compressor operation according to the present invention has following advantage: when the inductance value of the motor coil that is installed in compressor changes, therefore the capacitance that is connected to the capacitor of this motor also changes, Driven Compressor stably.
Should be appreciated that, under the prerequisite that does not deviate from essence of the present invention or substantive characteristics, the present invention can implement in many ways, so unless otherwise indicated, embodiment described above is not limited by any details of above stated specification, on the contrary, should do the understanding of broad sense in the spirit and scope that claims limited, therefore, those fall into institute in the claim scope and change or revise or equivalent that this scope is interior is all contained by claims.
