Description

Technical Field

[0001] This invention belongs to the field of air conditioning technology, and more specifically, relates to an air conditioner and a method for correcting the auxiliary heating power of the air conditioner. Background Technology

[0002] When an air conditioner is heating, it primarily generates heat through components such as the compressor and condenser. However, sometimes the heating effect may be insufficient, especially in cold winters or when the ambient temperature is very low. In such cases, the air conditioner will activate its electric auxiliary heating function, using electric heating elements to supplement heat and ensure that the indoor temperature reaches the set level.

[0003] However, in practice, the power supply voltage may fluctuate in some situations, resulting in two abnormal states: high voltage and low voltage. In this case, the power of the electric auxiliary heater will change with the voltage fluctuation, which will affect the final heating effect and may even damage the auxiliary heating element.

[0004] For example, but not limited to, existing methods for detecting the electric auxiliary heating power of air conditioners involve obtaining the fitted electric auxiliary heating power based on the current effective value of the power supply voltage, the current indoor unit evaporator temperature, and the current indoor unit fan speed; obtaining the electric auxiliary heating power compensation value based on the current indoor unit evaporator temperature and the current indoor unit fan speed; and determining the electric auxiliary heating power of the air conditioner based on the fitted electric auxiliary heating power and the electric auxiliary heating power compensation value. However, this solution only obtains the electric auxiliary heating power of the air conditioner through a purely software method and does not take into account the problem of inaccurate electric auxiliary heating power under harsh environments.

[0005] Existing technology also discloses an electric auxiliary heating control method, which determines the indoor unit heat exchanger temperature threshold that matches the actual fan speed of the indoor fan and is used to trigger the activation of the electric auxiliary heating; if the duration for which the indoor unit heat exchanger temperature is less than or equal to the indoor unit heat exchanger temperature threshold exceeds a first time threshold, and it is determined that the indoor ambient temperature meets the first electric auxiliary heating activation condition, the electric auxiliary heating of the air conditioner is activated. However, this solution also fails to consider that voltage fluctuations in harsh environments may cause the control algorithm to fail to track the control target in a timely manner, and the problem of inaccurate electric auxiliary heating power is still not solved. Summary of the Invention

If the bus voltage U BUS If it belongs to the third interval, the operating state is determined to be a high-voltage state;

[0031] If the operating state is the low-voltage state, the main control IC adjusts the PWM duty cycle signal sent to the control terminal of the controlled switch to increase the on-time of the controlled switch; if the operating state is the normal state, the main control IC maintains the PWM duty cycle sent to the control terminal of the controlled switch unchanged; if the operating state is the high-voltage state, the main control IC adjusts the PWM duty cycle signal sent to the control terminal of the controlled switch to decrease the on-time of the controlled switch.

Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this invention.

[0049] Embodiment 1 of the present invention provides an air conditioner, which includes: a power supply bus, a main control IC, a bus voltage detection circuit, a controlled switch, and an electric heating element.

[0050] like Figure 1 As shown, the electric heating element is switched on and off by the controlled switch; the control terminal of the controlled switch is connected to the main control IC; the bus voltage detection circuit is connected to the main control IC, and transmits the detected voltage signal U...s Send to the main control IC.

[0051] The bus voltage detection circuit, for example but not limited to, uses a voltage transformer, a voltage divider resistor, or optocoupler isolation to obtain the bus voltage U. BUS A small signal, i.e., a voltage signal U, that can be processed by the main control IC in a set proportion. s For example, but not limited to, such as Figure 2 As shown, the bus voltage detection circuit includes a first resistor MR1, a second resistor MR2, a third resistor MR3, a fourth resistor MR4, a capacitor MC1, and a first diode MD1. Preferably, but not limited to, the first resistor MR1 is 1MΩ, the second resistor MR2 is 1MΩ, the third resistor MR3 is 13kΩ, the fourth resistor MR4 is 1kΩ, and the capacitor MC1 is 10nF. At this time, U s =k·U BUS k = 6.5 × 10 -7 This involves reducing the voltage from several hundred volts to a range acceptable to the main control IC and then feeding it into the main control IC. Those skilled in the art should understand that... Figure 2 The circuit diagram shown is a simplified representation, including only the core components of each part and the basic connection relationships. The auxiliary components and specific parameters omitted in the diagram can be supplemented according to actual needs, and the implementation methods of each part are not limited to the scheme shown in the diagram.

[0052] The main control IC will detect the obtained voltage signal U s Transformed into bus voltage U BUS According to the bus voltage U BUS The operating status is determined by the interval to which it belongs, and the interval includes: the first interval [U safe- U D ), second interval [U D U M ], third interval (U M U safe+ ], where U D For less than the rated voltage U A Maximum floating voltage, U M For a voltage greater than the rated voltage U A Maximum upward fluctuation voltage, U safe- U safe+ These are the minimum and maximum permissible operating voltages, respectively. If the bus voltage U BUS If it belongs to the first interval, the operating state is determined to be low voltage, and the bus voltage U BUS If it belongs to the second interval, the operating status is determined to be normal. If the bus voltage U BUS If it belongs to the third interval, the operating state is determined to be high voltage. If the bus voltage U BUSBelonging to the first and third intervals, the main control IC corrects the conduction time of the controlled switch. Preferably, but not limitingly, the controlled switch is a power electronic switch, and the main control IC corrects the PWM duty cycle of the power electronic switch. Those skilled in the art should understand that when the bus voltage U BUS Less than the minimum allowable operating voltage U safe- Or greater than the maximum allowable operating voltage U safe+ When this happens, the air conditioner will shut down, therefore it is not within the scope of this invention.

[0053] One of the key features of this invention is the significant difference in adjustment coefficients between high-voltage and low-voltage conditions to achieve compensated control of electric heating power under different voltage states. Under high voltage, the electric heating voltage exceeds its rated voltage, resulting in excessive power output. This leads to excessive auxiliary heating capacity, deviating from the preset auxiliary heating capability. Furthermore, prolonged operation at high voltage reduces lifespan and may even damage the device. Therefore, under high voltage, the detected voltage needs to be converted into an adjustment coefficient that reduces the PWM duty cycle. Conversely, under low voltage, the electric heating voltage is below the rated voltage, resulting in insufficient power output. This means that when auxiliary heating is needed, the electric heating cannot achieve the required heating capacity. Therefore, under low voltage, the detected voltage needs to be converted into an adjustment coefficient that increases the PWM duty cycle.

[0054] Preferably, but not limitingly, the main control IC is based on the bus voltage U BUS The duty cycle adjustment factor is calculated as follows (1):

[0055]

[0056] In the formula:

[0057] u is the duty cycle adjustment factor.

[0058] When high-pressure or low-pressure conditions occur, the main control IC adjusts the duty cycle of the PWM controlling the controlled switch under normal conditions based on the obtained duty cycle adjustment coefficient u, as expressed by the following formula (4):

[0059] D u =u·D (2)

[0060] In the formula:

[0061] D u The corrected PWM duty cycle under high or low voltage conditions;

[0062] D represents the duty cycle of the PWM controlling the controlled switch under normal conditions.

[0063] Preferably, but not limitingly, the controlled switch is an IGBT; that is, in a preferred embodiment of the invention, the IGBT is used to control the on / off state of the electric heating element. The IGBT can perform high-frequency switching action using PWM waves. Compared to relays, the IGBT can respond to control signals and make corresponding changes more quickly. High-frequency switching action allows for control of the time the electric heating element is connected to the power supply bus.

[0064] Specifically, this invention uses a PWM wave to control the switching of the IGBT. When in a high-voltage state, the adjustment coefficient is to reduce the duty cycle of the PWM wave, thereby shortening the turn-on time of the IGBT. When in a low-voltage state, the adjustment coefficient is to increase the duty cycle of the PWM wave, thereby increasing the turn-on time of the IGBT.

[0065] More specifically, this invention regulates electric heating via an IGBT. The IGBT indirectly adjusts the timing of the electric heating circuit. Under high voltage, the PWM wave controlling the IGBT is affected by a high-voltage adjustment coefficient, resulting in a decreased duty cycle, shorter IGBT on-time, shorter electric heating circuit connection time, reduced operating time, and indirectly reduced output power. Under low voltage, the PWM wave controlling the IGBT is affected by a low-voltage adjustment coefficient, resulting in an increased duty cycle, longer IGBT on-time, longer electric heating circuit connection time, increased operating time, and indirectly increased output power.

[0066] Embodiment 2 of the present invention provides a method for correcting the auxiliary heating power of an air conditioner, comprising the following steps:

[0067] Step 1: The air conditioning unit's own bus voltage detection circuit detects the voltage of the power supply bus and transmits the detected voltage signal U. s Send to the main control IC.

[0068] Step 2: The main control IC follows the bus voltage U BUS The operating status is determined by the interval to which it belongs, and the interval includes: the first interval [U safe- U D ), second interval [U D U M ], third interval (U M U safe+ ], where U D For less than the rated voltage U A Maximum floating voltage, U M For a voltage greater than the rated voltage U A Maximum upward fluctuation voltage, U safe- U safe+ These are the minimum and maximum permissible operating voltages, respectively. If the bus voltage UBUS If it belongs to the first interval, the operating state is determined to be low voltage, and the bus voltage U BUS If it belongs to the second interval, the operating status is determined to be normal. If the bus voltage U BUS If it falls within the third range, the operating state is determined to be high voltage. Those skilled in the art should understand that when the bus voltage U... BUS Less than the minimum allowable operating voltage U safe- Or greater than the maximum allowable operating voltage U safe+ When this happens, the air conditioner will shut down, therefore it is not within the scope of this invention.

[0069] Step 3: If the current operating condition is low voltage, the main control IC adjusts the PWM duty cycle signal sent to the control terminal of the controlled switch to increase the on-time of the controlled switch; if the current operating condition is normal, the main control IC maintains the PWM duty cycle sent to the control terminal of the controlled switch unchanged; if the current operating condition is high voltage, the main control IC adjusts the PWM duty cycle signal sent to the control terminal of the controlled switch to decrease the on-time of the controlled switch.

[0070] In other words, under high voltage conditions, the PWM wave controlling the IGBT is affected by the high voltage adjustment coefficient, resulting in a decrease in the duty cycle, a decrease in the IGBT turn-on time, a shorter time for the electric heating circuit to be connected, a reduction in the operating time, and an indirect decrease in the output power. Under low voltage conditions, the PWM wave controlling the IGBT is affected by the low voltage adjustment coefficient, resulting in an increase in the duty cycle, an increase in the IGBT turn-on time, an increase in the time for the electric heating circuit to be connected, an increase in the operating time, and an indirect increase in the output power.

[0071] Preferably, but not limitingly, step 3 specifically includes:

[0072] Step 3.1: For low-voltage and high-voltage conditions, based on the bus voltage U BUS The duty cycle adjustment factor is calculated and expressed by the following formula (3):

[0073]

[0074] In the formula:

[0075] u is the duty cycle adjustment factor.

[0076] Step 3.2: Based on the duty cycle adjustment coefficient u obtained in Step 3.1, adjust the duty cycle of the PWM controlling the controlled switch under normal operating conditions, as expressed by the following formula (4):

[0077] D u =u·D (4)

[0078] In the formula:

[0079] D u The corrected PWM duty cycle under high or low voltage conditions;

[0080] D represents the duty cycle of the PWM controlling the controlled switch under normal conditions.

[0081] One of the most prominent and substantial features of this invention is that it determines the high and low voltage status by detecting the bus voltage, and then adjusts the PWM waveform controlled by the bus voltage change rate to adjust the working time of the IGBT for auxiliary heating, thereby achieving control over the output power. This solves the problem of fine-tuning the electric auxiliary heating, especially the problem of inaccurate electric auxiliary heating power under harsh environments. The significant advancements this brings to the prior art include at least: achieving fine-tuning of electric auxiliary heating power; improving the accuracy of electric auxiliary heating power output, which is beneficial for the normal and effective operation of air conditioning units.

[0082] Embodiment 3 of the present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is loaded onto the processor, it implements an air conditioning auxiliary heating power correction method according to Embodiment 2.

[0083] Embodiment 4 of the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements an air conditioning auxiliary heating power correction method according to Embodiment 2.

[0084] It is worth noting that in the embodiments of the present invention, "steps + numbers" is only an expression for clearly describing a specific implementation method of an air conditioner and its auxiliary heating power correction method, and is not an absolute limitation on the order of the steps. Under the guidance of the core concept of the present invention, changing the order of these steps to obtain the same or similar technical effects all fall within the scope of the present invention.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the protection scope of the claims of the present invention.
