Description

Technical Field

[0001] The present invention belongs to the technical field of circuit control, and in particular relates to a compressor startup control method, device, compressor and storage medium. Background Art

[0002] Compressors are crucial components in all types of refrigeration systems. During operation, they compress low-temperature, low-pressure refrigerant into high-temperature, high-pressure gas, thereby achieving cooling through heat conversion. In cold temperatures, due to the refrigerant's tendency to migrate to cooler locations, liquid refrigerant can enter the compressor's compression chamber through the compressor's air inlet or exhaust port when the compressor is at a low temperature (i.e., compressor flooding). Because liquid refrigerant is difficult to compress, starting the compressor flooded with liquid can subject the compressor bearings to irregular lateral impacts, shortening the compressor's lifespan.

[0003] In the prior art, in order to prevent the compressor from starting with liquid, a heating tape is usually added to the bottom of the compressor to heat the compressor, thereby preventing liquid refrigerant from entering the compressor.

[0004] However, the inventors have discovered that the prior art has at least the following technical problems: adding a heating tape to the bottom of the compressor will increase the manufacturing cost of the electrical appliance containing the compressor. Summary of the Invention

[0035] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0036] Currently, compressors are found in a variety of components, including air conditioners, centrifugal chillers, and heat pumps. Compressors compress low-temperature, low-pressure refrigerant to produce high-temperature, high-pressure gas, thereby achieving temperature exchange and imparting kinetic energy to the refrigerant. However, due to the refrigerant's tendency to migrate to cooler locations, when the compressor temperature is low, liquid refrigerant will enter the compressor through the air inlet or outlet, causing compression when the compressor starts. Since liquid refrigerant is difficult to compress, the compressor is subjected to significant lateral impact forces during startup, damaging the compressor bearings and reducing their lifespan.

[0037] To reduce the risk of compressors starting with liquid, conventional heating tape is often added to the bottom of the compressor to heat the compressor before starting. However, adding a heating tape to the bottom of the compressor increases the manufacturing cost of the electronic equipment containing the compressor.

[0038] In response to the above technical problems, the inventors proposed the following technical concept: adding a starting switch between the existing running winding and the starting capacitor, and connecting the power supply through the power switch module, by obtaining the ambient temperature and the operation record of the compressor, calculating the time difference between the compressor shutdown time in the operation record and the current time, controlling the closing and opening of the starting switch according to the ambient temperature and the time difference, and controlling the power switch module to connect to the first voltage of the power supply, so as to complete the heating of the compressor by passing the current through the running winding. After heating for a preset time, the starting switch is controlled to close, and the power switch module is controlled to connect to the second voltage of the power supply to start the compressor.

[0039] Figure 1 This is a schematic diagram of the structure of the compressor provided in the embodiment of the present application. Figure 1The compressor 100 includes: a controller 101, a running winding R1, a starting winding R2, a starting capacitor C, a power switch module 102 and a starting switch Ks; one end of the running winding R1 is connected to one end of the starting winding R2, and the common end of the connected windings is connected to a first end of the power switch module 102, a second end of the power switch module 102 is connected to one end of a power supply, the other end of the starting winding R1 is connected to the starting capacitor C and the starting switch in sequence, and then connected to the other end of the power supply 103, and the other end of the running winding R2 is connected to the starting switch Ks and one end of the power supply 103.

[0040] Among them, the power supply 103 includes: a first power supply U1 and a second power supply U2, and the power switch module 102 includes: a first switch K1 and a second switch K2. The common end of the first switch K1 and the second switch K2 serves as the first end of the power switch module 102, the other end of the first switch K1 is connected to the first power supply U1, and the other end of the second switch K2 is connected to the second power supply U2.

[0041] The controller 101 may include a data processing element such as a CPU (central processing unit), an ECU (electronic control unit) or a control board; and may also include a storage device, which may be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random-access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk.

[0042] In a specific implementation, the controller 101 is used to obtain the ambient temperature and the operation record of the compressor, and further control the start switch Ks and the power switch module 102 according to the ambient temperature and the operation record of the compressor. The connection between the controller and the start switch Ks and the power switch module 102 can be a communication connection.

[0043] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the compressor startup control method. In other feasible embodiments of the present application, the above architecture may include more or fewer components than shown, or may combine or split certain components, or arrange the components differently. The specific configuration may be determined based on the actual application scenario and is not limited here. Figure 1 The components shown can be implemented in hardware, software, or a combination of software and hardware.

[0044] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0045] Figure 2 A flow chart of the compressor startup control method provided by the embodiment of the present application. The execution subject of the embodiment of the present application may be Figure 1 The controller in this embodiment is not particularly limited to this. Figure 2 As shown, the method includes:

[0046] S201: When a start signal is received, the ambient temperature of the compressor and the operation record of the compressor are obtained.

[0047] In this step, the start signal may be input manually or received from other components.

[0048] Among them, other components may be a mainboard, a processor, a programmable logic controller and other components connected to the compressor.

[0049] S202: Calculate the time difference between the compressor downtime in the operation record and the current time to obtain the downtime duration.

[0050] In this step, the time difference between the compressor downtime in the operation record and the current time is calculated. The method can be to subtract the compressor downtime in the operation record from the current time. The current time can be obtained through the network or recorded from the first operation of the compressor.

[0051] S203: If the ambient temperature meets the preset temperature condition and the shutdown time meets the preset time, the start switch is controlled to be disconnected, and the power switch module is controlled to connect the first voltage of the power supply to heat the compressor according to the preset power-on time.

[0052] In this step, the ambient temperature satisfies the preset temperature condition, which may be that the ambient temperature is lower than a preset temperature value, and the downtime meets the preset time, which may be that the downtime is within a preset interval. Controlling the start switch to disconnect may be sending an electrical signal to the start switch to disconnect or close the start switch. The power supply can output different voltage values and DC or AC voltages. The preset power-on time may be pre-set, or may be determined based on the downtime and / or the ambient temperature, or may be selected from several preset time lengths based on the downtime and / or the ambient temperature. The first voltage for turning on the power supply may be controlling the power switch module to connect to the first power supply, specifically, closing the first switch.

[0053] The start switch can be a relay switch. The ambient temperature can be obtained by a copper drum temperature sensor, which can be a contact temperature sensor or a non-contact temperature sensor. The temperature sensor can be composed of one temperature sensor or multiple temperature sensors. It can be installed outside or inside the compressor.

[0054] S204: After a preset power-on time has passed, the start switch is controlled to close and the power switch module is controlled to connect to the second voltage to start the compressor.

[0055] In this step, controlling the start switch to be closed may be sending an electrical signal to the start switch. Connecting the second voltage may be controlling the power switch module to be connected to the second power supply, specifically, closing the second switch.

[0056] As can be seen from the description of the above embodiment, the embodiment of the present application controls the start switch to be disconnected when the ambient temperature meets the preset temperature condition and the shutdown time meets the preset time, so that the current only passes through the running winding, thereby achieving heating of the compressor when the compressor is not running, avoiding the compressor from starting with liquid. Subsequently, after the compressor is heated for the preset power-on time, the start switch is controlled to be closed, and the power switch module is controlled to connect the second voltage, so that the second voltage passes through the running winding and the start winding, so that the compressor starts normally. Since the embodiment of the present application uses the compressor's own running winding to heat the compressor, it can reduce the manufacturing cost of equipment with a compressor.

[0057] In one possible implementation, in step S203, if the ambient temperature satisfies a preset temperature condition and the shutdown duration satisfies a preset duration, controlling the start switch to be turned off and controlling the power switch module to be connected to the first voltage of the power supply, and heating the compressor according to the preset power-on duration, specifically includes:

[0058] S203A: If the ambient temperature meets the preset temperature condition and the shutdown time meets the preset time, the start switch is controlled to be disconnected, the first switch is controlled to be closed and the second switch is controlled to be disconnected so that the first power supply outputs the first voltage and the compressor is heated according to the preset power-on time.

[0059] In this step, the preset temperature condition may be that the temperature is less than a preset value.

[0060] For example, the ambient temperature is less than 0° C., or less than -2° C., etc., which is not specifically limited in this application. The preset power-on time can be 3 minutes, 5 minutes, or 30 seconds, etc.

[0061] In the above step S204, after the preset power-on time has elapsed, controlling the start switch to close and controlling the power switch module to connect to the second voltage to start the compressor specifically includes:

[0062] S204A: After a preset power-on time, the start switch is controlled to be closed, the first switch is controlled to be opened, and the second switch is controlled to be closed so that the second power supply outputs a second voltage to start the compressor.

[0063] In this step, the second voltage may be greater than the first voltage, and the second voltage is mainly used to enable the compressor to start normal operation.

[0064] The first switch and the second switch may also be relay switches.

[0065] In one possible implementation, in step S203, if the ambient temperature satisfies a preset temperature condition and the shutdown duration satisfies a preset duration, controlling the start switch to be turned off and controlling the power switch module to be connected to the first voltage of the power supply, and heating the compressor according to the preset power-on duration, includes:

[0066] S203B: If the ambient temperature is less than the first preset value and the shutdown time is greater than 0, the preset power-on time of the running winding is determined according to the shutdown time, and the start switch is controlled to be disconnected, and the power switch module is controlled to connect the first voltage of the power supply, and the compressor is heated according to the preset power-on time.

[0067] In this step, the first preset value can be a preset temperature value, and the preset power-on time of the running winding is determined according to the shutdown time. The preset power-on time can be calculated from the shutdown time according to a preset functional relationship, or a preset power-on time can be selected from multiple preset power-on time periods based on the value of the shutdown time.

[0068] For example, the first temperature value may be 0°C, -1°C, or -3°C.

[0069] From the description of the above embodiments, it can be seen that the embodiments of the present application can make the preset power-on time more suitable for the current shutdown time by determining the preset power-on time of the running winding according to the shutdown time, thereby accurately controlling the compressor temperature and avoiding the problem of energy waste caused by the compressor temperature remaining low after heating or the heating time being too long.

[0070] In a possible implementation, in step S203B, determining the preset energization duration of the running winding according to the shutdown duration includes:

[0071] S203B1: If the shutdown time is greater than 0 and less than the preset time, the preset power-on time is determined as the first power-on time.

[0072] In this step, the preset duration can be 10 minutes, 15 minutes, 30 minutes, 15 minutes and 20 seconds, etc., and the first power-on duration can be 1 minute, 3 minutes, etc. This application does not impose any specific restrictions on this.

[0073] S203B2: If the shutdown time is greater than or equal to the preset time, determine the preset power-on time as the second power-on time.

[0074] In this step, the second power-on duration can be 5 minutes, 7 minutes, etc., and this application does not impose any specific restrictions on this.

[0075] In the above steps S203B1 and S203B2, the second power-on duration is greater than the first power-on duration.

[0076] From the description of the above embodiment, it can be seen that the embodiment of the present application determines the interval range of the shutdown time and adopts a longer second power-on time when the shutdown time is longer, thereby achieving sufficient heating of the compressor.

[0077] In one possible implementation, in step S203, if the ambient temperature satisfies a preset temperature condition and the shutdown duration satisfies a preset duration, controlling the start switch to be turned off and controlling the power switch module to be connected to the first voltage of the power supply, and heating the compressor according to the preset power-on duration, includes:

[0078] S203C: If the ambient temperature is greater than or equal to the first preset value and less than the second preset value, and the shutdown time is greater than or equal to the preset time, the start switch is controlled to be disconnected, and the power switch module is controlled to connect the first voltage of the power supply to heat the compressor according to the preset power-on time.

[0079] In this step, the first preset value may be the same as the first preset value. The second preset value may be a value greater than the first preset value. The preset power-on duration may be the first power-on duration.

[0080] For example, the second preset value may be 1°C, 3°C, or 5°C.

[0081] As can be seen from the description of the above embodiment, the present embodiment achieves heating of a compressor that is at a high temperature but has been down for a period of time greater than a certain value by controlling the start switch to disconnect and the power switch module to connect the first voltage when the ambient temperature is between a first preset value and a second preset value and the downtime is greater than or equal to the preset time. Similarly, by eliminating the need for additional heating components, the technical effect of reducing manufacturing costs is achieved.

[0082] In a possible implementation, after calculating the time difference between the compressor downtime in the operation record and the current time to obtain the downtime duration, step S202 further includes:

[0083] S203D: If the ambient temperature does not meet the preset temperature condition, and / or the shutdown time does not meet the preset time, the start switch is controlled to close and the power switch module is controlled to connect the second voltage to directly start the compressor.

[0084] In one possible implementation, in this step, the ambient temperature does not meet the preset temperature condition, and / or the shutdown time does not meet the preset time, including: the ambient temperature is greater than or equal to the first preset value and less than the second preset value, and the shutdown time is less than the preset time; or, the ambient temperature is greater than the second preset value.

[0085] For example: if the ambient temperature is greater than 10°C, the start switch can be controlled to close and the power switch module can be controlled to connect to the second voltage to directly start the compressor; if the ambient temperature is greater than 3°C and the downtime is less than 10 minutes, the start switch can be controlled to close and the power switch module can be controlled to connect to the second voltage to directly start the compressor; if the ambient temperature is less than 0 degrees but the downtime is less than 5 minutes, the start switch can be controlled to close and the power switch module can be controlled to connect to the second voltage to directly start the compressor.

[0086] From the description of the above embodiments, it can be seen that the embodiments of the present application control the starting switch to close and the power switch module to connect to the second voltage when the ambient temperature does not meet the preset temperature conditions and / or the shutdown time does not meet the preset time, so as to directly start and run the compressor without heating the compressor, thereby reducing energy consumption and speeding up the starting time of the compressor.

[0087] In the above embodiments, the voltages of the first energy source and the second power source may be 12V, 22V, 30V, 120V or 220V, etc., and this application does not impose any specific restrictions on this.
