Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to the accompanying drawings control system and the method for compressor in the air-conditioner of the embodiment of the present invention and air-conditioner are described.
Fig. 1 is the block diagram of the control system of compressor in the air-conditioner according to embodiment of the present invention proposition.
As shown in Figure 1, compressor 10 has main winding 101 and auxiliary winding 102, main winding 101 and auxiliary winding 102 are arranged in orthogonal space mode, and one end of main winding 101 is connected with one end of auxiliary winding 102, have first node between one end of main winding 101 and one end of auxiliary winding 102.Wherein, main winding 101 and auxiliary winding 102 all can be arranged on the stator of compressor, and more specifically, main winding 101 and auxiliary winding 102 are all arranged on the stator of drive motors in compressor 10.According to a concrete example of the present invention, the drive motors of compressor 10 can be single-phase asynchronous motor.
As shown in Figure 1, the control system 20 of compressor comprises: power supply 201, electric capacity C1, switch element 202 and control unit 203.Power supply 201 is for powering for compressor 10, and one end of power supply 201 is connected with the other end of main winding 101, and the other end of power supply 201 is connected with first node; One end of electric capacity C1 is connected with the other end of auxiliary winding 102; One end of switch element 202 is connected with the other end of main winding 101, and the other end of switch element 202 is connected with the other end of electric capacity C1.
Control unit 203 is for obtaining the operational mode of air-conditioner, and when operational mode is heating mode, the first gauge tap unit 202 of control unit 203 is in on-state to start compressor 10, and compressor 10 start after again gauge tap unit 202 be in off-state, to improve the heating capacity of air-conditioner.That is, in a heating mode, control unit 203 gauge tap unit 202 after compressor 10 starts disconnects, cuts off the loop of electric capacity C1 and auxiliary winding 102 formation, the electric energy that power supply 201 exports flows through main winding 101 and does not flow through auxiliary winding 102, thus the input power of compressor 10 increases, the heating capacity of air-conditioner improves.
In addition, it should be noted that, when single-phase sinusoidal current is by main winding 101, the drive motors of compressor will produce an alternating magnetic field, the power of this alternating magnetic field and direction be the change of intercropping sine gauge rule at any time, but be fixing on dimensional orientation, and this alternating magnetic field can be analyzed to that two rotating speeds are identical, the rotating excitation field of rotation direction contrary (such as clockwise and counterclockwise) each other.The conductor of these two rotating excitation field cutting rotors, and in the conductor of rotor, produce induced electromotive force and induced-current respectively, this induced-current and this two rotating excitation fields interact and produce both direction torque contrary each other, wherein, clockwise torque makes rotor clockwise rotate, counterclockwise torque makes rotor rotate counterclockwise, and it is exactly the synthesis torque that pushing motor rotates that these two torques stack up.
When rotor rotates to a direction (such as clockwise), cutting magnetic line movement between the rotating excitation field that rotor and clockwise direction rotate diminishes, cutting magnetic line movement between the rotating excitation field that rotor and counter clockwise direction are rotated becomes large, the synthesis torque that rotor produces will be no longer zero, and rotor will rotate along pushing direction.But suppose that rotor is static, these two rotating excitation fields produce the contrary torque in two equal and opposite in directions, direction in the rotor, make synthesis torque be zero, rotor can not produce torque, so motor self cannot rotate from halted state.
Thus, spatially differ the auxiliary winding 102 of 90 degree by increasing by one with main winding 101, the drive motors of compressor can be rotated automatically.In addition, the electric capacity C1 that also serial connection one is suitable on auxiliary winding 102, makes the electric current of auxiliary winding 102 differ 90 degree, i.e. so-called point of facies principle with the electric current of main winding 101 is approximate in phase place.Such two electric currents differing 90 degree in time pass into the winding that two spatially differ 90 degree respectively, and will spatially produce two-phase rotating excitation field, under rotating excitation field effect, rotor just can rotate automatically.
As mentioned above, in air-conditioner running, control unit 203 can Real-Time Monitoring whether receive user input mode instruction, when user inputs heating mode instruction, air-conditioner runs with heating mode, control unit 203 gauge tap unit 202 is in on-state simultaneously, the alternating current of now power supply 201 output is respectively by main winding 101 and auxiliary winding 102, start under the rotating excitation field effect that compressor 10 can produce at main winding 101 and auxiliary winding 102, now control unit 203 judges whether compressor 10 starts further, control unit 203 compressor 10 start after again gauge tap unit 202 be in off-state, the alternating current of now power supply 201 output is respectively by main winding 101, and not by auxiliary winding 102, rotating excitation field is synthesized by main winding 101 and the rotor of compressor 10, negative sequence field is large, the loss brought is large, the input power of the drive motors of compressor 10 increases, thus improve the heating capacity of air-conditioner.
