Description of the Invention (i) [Field of the Invention] The present invention relates to a compressor frequency conversion control device, in particular to a method that can precisely control the compressor motor speed by controlling the output frequency of the frequency converter And the inverter frequency control device for energy saving. 5 [Description of Know-how] There are not only many types of compressors, but also a wide range of uses. For example, various air compressors, gas compressors, or refrigerant compressors are all applications of compressors. As for the refrigerant compressors (hereinafter referred to as compressors) used in general small air conditioners, they usually use a DC motor to drive the compressor. Therefore, the AC mains must be converted into a DC voltage before the motor can be driven. However, because the traditional air conditioner is in operation, the way to control the room temperature is when the room temperature drops below a preset value, for example, 3 degrees lower than the preset value, the compressor will stop running until the room temperature rises. When the preset value is exceeded, such as 3 degrees higher than the preset value, the compressor starts to run again. However, this control method not only makes people feel that the temperature difference changes too much and feels uncomfortable, but also the compressor is repeatedly stopped, Under startup, it is not only easily damaged but also consumes more power. Therefore, a so-called, frequency conversion compressor is born. However, because this inverter compressor uses a DC motor, it is not actually a frequency inverter. Instead, it changes the DC motor in time by changing the duty cycle of the DC voltage sent to the DC motor. Rotation speed makes the rotation speed of the motor slower when the room temperature is lower than a preset temperature, and makes the rotation speed of the motor faster when the room temperature is relatively ordinary, so that the control room s 4 ^, w to / dish It can be changed within a small range to achieve the effect that the motor can continue to run and save power in a timely manner. Therefore, the above-mentioned compressor can only be said to be a 'transformer compressor'. Moreover, because the above compressor uses a DC motor with only small horsepower, it cannot be applied to the Chinese National Standard (CNS) A4 specification (210X297 mm) on the paper scale.

As a result, larger compressors are often used on large machines. However, the current AC compressor does not have a frequency conversion function, so that the conventional compressor cannot effectively reduce the power consumed by the motor when the system requirements change. 5 In addition, in the current compressor control method, whether it is a frequency conversion or non-frequency conversion compressor, when an abnormal situation occurs, there is no other way to respond except to issue a warning signal or jump, so that the user must In the event of a machine crash, emergency investigation and maintenance are performed to enable the compressor to resume operation as soon as possible in a short period of time. [Summary of the invention] Therefore, the object of the present invention is to provide a compressor frequency conversion control device, which controls the frequency output of the frequency converter to achieve accurate control of the speed of the AC compressor motor and save energy in proportion. Therefore, the compressor frequency conversion control device of the present invention, wherein the compressor 15 is an AC compressor, which is connected to a frequency converter, and is controlled by the output frequency of the frequency converter to control its motor speed. The compressor frequency conversion control device is combined with an arithmetic unit and a logic controller to control the frequency converter and the compressor to control the output frequency of the frequency converter according to the feedback signal of the compressor. The motor speed, thereby achieving the purpose of accurately controlling the motor speed of the compressor 20 and saving energy in proportion. [Brief description of the formula] Other features and advantages of the present invention will be clearly understood in the following detailed description of the preferred embodiment with reference to the drawings.

[Detailed description of the preferred embodiment] Referring to the first figure, it is a circuit block diagram of a preferred embodiment of the frequency conversion control device of the compressor of the present invention. The compressor is an AC compressor, which is mainly used in On large machines, there is an AC 10-flow motor (not shown) that can generate high horsepower. In this embodiment, the compressor 1 is connected to an inverter 2, which can be changed according to an input control signal. Its output frequency is used to control the motor of the compressor 1 to change the rotation speed relatively. And because the operating principle of general AC compressors and inverters should already be familiar to those who are familiar with the relevant fields, it will not be explained here. The frequency conversion control device 3 (hereinafter referred to as the frequency conversion control device 3) of the compressor 15 of the present invention is used to control the frequency converter 2 so that the frequency converter 2 can relatively change its output frequency according to the control signal output by the frequency conversion control device 3, and further The motor of the compressor is controlled to change the rotation speed relatively. Referring to the second figure, the variable frequency control device 3 of the present invention can be said to be a type of FUZZY controller, in which an arithmetic unit and a logic controller are mainly combined (or integrated). This operator is actually composed of a composite PID (proportional_integral-derivative) controller. The general PID controller is usually composed of three parts: two proportional units, integral units and differential units. It is driven by the system command and the feedback signal of the controlled equipment, and 25 is controlled by the respective output superposition to form the output signal of the system to control the controlled equipment. ) A4 specification (0X297 public director) ------ 530123 A7 ------- B7_ V. Invention Lion (4) ": --- But it is prone to occur due to general PID controllers 〇versh〇〇t ( (Overshooting) phenomenon, which makes the system oscillate near the target value, causing the system to be unstable, so that the speed of the controlled motor is unstable, which cannot effectively save power. Therefore, the composite PID controller used in the present invention is different from the above general piD controller in that it is composed of a plurality of proportional devices, a plurality of integral controllers and a plurality of differential controllers, and the composite PID controller The characteristic of the device is that after the input feedback hbl passes through multiple operations of the proportional, integral, and differential controllers, the system will eventually reach the target value accurately and stabilize, without generating an overshoot phenomenon. . Therefore, when the composite piD controller compares a feedback signal output from the 10 controlled device with a desired value, the control signal generated by it can accurately control the controlled device to a desired value. The logic controller contains the control logic functions required by various compressors to detect and measure the various states of the compressor to control the operation of the compressor in a timely manner. And as shown in the second figure, in this embodiment, the variable frequency control device 3 is made in a single chip and implanted into a circuit board (not shown) to become a variable frequency control module, and the composite type The PID controller and the logic controller can be implemented by software programs or hardware logic respectively, and are built in the single chip, that is, the frequency conversion control device 3.

In addition, when I determine the value according to the PID control $ [" ¥ ^ " ^ value, when the compressor receives the demand to increase the sfL number and needs to increase its motor speed, the piD controller will issue a 丨 increased speed 丨The control signal is given to the inverter to change the output frequency and control the motor of the compressor to increase the speed. Conversely, when the compressor receives a "reduction in demand" signal and needs to reduce the speed of its motor, the PID controller sends a | reduction speed | control signal to the inverter to reduce the output frequency to control the compressor motor to reduce the speed. In addition, in the case of "i 15 constant pressure operation according to the PIDi controller setting, when encountering ', abnormal,': make the compressor empty after the stop button is pressed and then stop (please read the precautions on the back before filling in this (Page)-Order-20 25 In addition, when an abnormality occurs in the system and the abnormality is not caused by the compressor's failure, but the compressor motor is fully loaded at the maximum speed, for example, the load current of 3000rpm is too high, which meets the frequency conversion control device When the preset speed of 3 is reached, the frequency conversion control device 3 sends a control signal to set the maximum speed of the motor to a lower speed, so that the maximum speed of the motor is reduced. Thus, the speed of the motor is reduced. It will “return to the set value” (ie, lower speed) and reduce the load current. At this time, unless the system is abnormal, the set upper limit value is reached ”(that is, the upper limit of the set lower maximum speed is reached) The compressor will make this load-reducing function only when it is explained in more detail below. Therefore, when the traditional AC compressor without frequency conversion function is matched with a frequency converter, the paper size of this paper applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 530123 A7 B7 V. Description of the invention 10 10 15 20 25 After the invention of the variable frequency control device 3, it becomes a variable frequency compressor that can accurately control its output pressure or temperature by changing its motor speed in time according to the system feedback signal. Therefore, from the above control flow of the frequency conversion control device 3, it can be known that the frequency conversion control device 3 receives a feedback signal (possibly a pressure signal or a temperature signal, etc.) output by the compressor, and this signal comes from the pressure at the compressor discharge end The sensor or ice water temperature sensor of the ice water machine converts the pressure (or temperature) into a feedback signal and transmits it to the frequency conversion control device 3. The inverter control device 3 compares the feedback signal with a desired value by the compound PID control | §, and the expected value is usually the set value that the user expects the compressor to reach. Therefore, according to the working principle of the compound PID, the feedback signal is first subtracted from the expected value to generate an error signal, and then the error signal is multiplied by a constant by the proportional controller, and then passed through the multiple differential controller and integral control. After the operation of the device, a control signal is generated to the inverter, so that the output frequency is relatively changed according to the control signal, so that the motor speed of the compressor is changed to meet the requirements of the expected value. In this way, the output of the AC compressor can be accurately controlled, so that the energy consumed by the system of the compressor can be increased or decreased with the motor speed to an almost equal proportion while maintaining the precise pressure or temperature, thereby achieving energy conservation. the goal of. In addition, as mentioned above, in addition to the function of controlling the frequency conversion of the AC compressor, the frequency conversion control device also provides a load reduction function for its unit. This function allows the unit to reduce the unit when it encounters non-faulty abnormalities. The performance and warning methods allow users to be more flexible and perform maintenance without jumping. The following examples illustrate it. Example: When the frequency control device 3 is applied to the constant pressure of the compressor exhaust page 13 This paper size applies Chinese National Standard (CNS) A4 specifications (210 ^ 297 mm) (Please read the precautions on the back before filling this page )., May | 530123 A7 ---------- B7 __ V. Description of the invention) One of the biggest advantages of the frequency compressor is that the exhaust pressure is under the condition of constant pressure. Change and adjust the motor speed of the compressor. Assuming its speed range is set to 1000 rpm ~ 300 rpm, 3000 rpm is the full load speed. This means that under normal conditions, the inverter compressor can Variable speed between 1000rPm ~ 3000rpm. However, when the compressor's intake air pressure causes the compressor to be fully loaded at 3000 rpm and the load current is too high due to system abnormalities, the current existing compressors generally respond to trips until the system is restored. Do not power on again until normal. However, since the change in the system's air intake pressure is not caused by the failure of the compressor itself, it does not need to be stopped immediately. Therefore, the frequency conversion control device 3 of the present invention is further designed with a load reduction function. Change, use an intake pressure sensor to sense the pressure and return a feedback signal to the frequency conversion control device 3, so that the PID controller compares the difference between the preset parameter and the feedback signal, and generates a control signal to reduce compression The maximum speed of the machine is adjusted, for example, from 15 rpm to 3000 rPm to 1000 rpm to 2800 rpm, and the lowered maximum speed can be fixed or maneuverable according to the change in intake pressure. Therefore, as the speed of the motor is reduced, the load current will be reduced accordingly, thereby avoiding excessive current caused by the change of the intake pressure. Unless the system's intake air pressure value changes after reducing the speed, the compressor will only trip when the maximum change value of 20 (that is, the difference between the intake air pressure and the standard value reaches the maximum set value). It is still possible to perform maneuverability control between a lower speed and the standard maximum speed, and at the same time reduce the maximum speed, send a warning # Tiger to remind the user. Example 2: Frequency conversion control device 3 is used when the temperature of the ice water machine is 25. The ice water machine uses a refrigerant compressor to compress the refrigerant, and passes the condenser to ________. Page 14 This paper applies the Chinese National Standard (CNS) A4. Specifications (210X297 Gongchu) (Please read the notes on the back before filling this page) -Order | 530123 A7 ----——- ____ B7 V. Description of the invention (12) ^ '----— Refrigerant cooling liquefaction After that, it passes through the expansion valve to the evaporator, and then sends the refrigerant to heat exchange with water or other media, and then sends the cooled ice water to the place where air conditioning or cooling is needed. Regardless of whether it is a variable frequency ice water machine or a variable frequency, tuning, a fixed operating value is used, for example, the ice water outlet temperature 5 or the gas outlet temperature is fixed, and then the second frequency is made according to this operating value. As mentioned above, assuming that the speed of the inverter compressor is l_rPm ~ 3_rpm, the speed of the refrigerant shrinking machine can be between 1000rpm and 3000rpm, and it will automatically increase or decrease depending on the change of the ice water temperature. However, because the condensation requires external cooling water or air for cooling, when the condenser scale increases the cooling water line temperature, the condensation temperature will also increase, and the increase in condensation temperature will increase the pressure and compress the refrigerant. The temperature at the outlet of the machine rises. When the temperature rises to a certain value, in order to protect the compressor, the current practice is to make the compressor trip. However, condenser fouling is not caused by the compressor's failure and does not require immediate shutdown. Therefore, with the frequency conversion control device 3 of the present invention, a temperature sensor can be used to convert the sensed temperature into a feedback signal based on the exhaust temperature of the compressor's outlet 15 and return it to the frequency conversion control device 3, so that the comparison can be made in advance. After inputting the parameters, a control signal is generated to reduce the maximum speed of the compressor, so that the speed is adjusted to 1000 rpm ~ 2800 rpm, and this maximum speed can be adjusted or adjusted according to the exhaust temperature or pressure. After reducing the speed by 20, the load current of the motor will also decrease, and the amount of refrigerant at the outlet will decrease, so the cold / spin pressure or condensation temperature will be reduced. Unless the condensing pressure or temperature continues to rise to a higher value, the system will trip. Similarly, when the variable frequency control device 3 is used in a variable frequency heat pump, the hot water or hot air outlet temperature of the condenser can be used as a reference, and other abnormal conditions 25 can be used as a reference value for reducing the maximum speed.

Invention Explanation (13) Therefore, the frequency conversion control device 3 uses the function of lowering the maximum speed to reduce the full load or other characteristics to make the frequency conversion-driven unit under an operating condition based on a certain output characteristic, if it encounters an abnormal situation, And this abnormal situation does not come from the compressor itself, and it is the one that enables the frequency conversion unit to reduce the maximum speed by reducing the maximum speed of 5 speeds. According to the user's needs, according to the preset parameters, select some abnormal conditions as the target to reduce The function of the highest speed, only when the situation is more serious, the machine will trip. In addition, the function of lowering the maximum speed of the frequency conversion control device 3 may reduce the full load of the frequency conversion unit under normal conditions, but it can provide users with a longer abnormal response processing time. As for the inverter host of the air-conditioning system, it is better to increase the temperature of the system due to the abnormal load caused by the load shedding. This is better than turning the office into a large oven due to the green jump. Furthermore, the variable frequency control device 3 of the present invention has been implemented and actualized, and can be practically applied to traditional compressors. The internal settings made by the variable frequency control device 3 for different application examples will be listed below. (1) When applied to a spiral air compressor

Description of the invention 5 10 15 31.YUNN: 1… The application software of the ice water machine In summary, the frequency conversion control device 3 of the present invention has a composite piD controller and various control functions required by the compressor. The logic controller is integrated and built in a single chip, which not only has the characteristics of high accuracy, fast response and reliable production, but also the frequency conversion control device 3 can control the inverter according to the feedback signal of the controlled system. The output frequency changes the motor speed of the compressor to achieve the purpose of precise control of pressure or temperature, and its accuracy can be adjusted according to the use requirements. At the same time, due to the change of the motor speed, the energy consumed by the system can be increased or decreased with the rotation speed to almost the same proportion under the condition of maintaining accurate pressure or temperature, thereby achieving the purpose of saving energy. In addition, with the load reduction function of the frequency conversion control device 3, when the unit encounters a non-faulty abnormality, it can first reduce the unit's performance and speed and give a warning, so that the user can calm down without jumping. Strain. However, the above are only the preferred embodiments of the present invention.
