Description

TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, and particularly relates to an air conditioner and a running control method of the air conditioner. BACKGROUND

[0002] The application scenarios of air conditioners are more and more extensive, and the types of air conditioners are gradually diversified, for example, there are split wall-mounted air conditioners, cabinet air conditioners and integrated mobile air conditioners. The air outlet of the air conditioner is usually provided with a guide vane for realizing the air supply function.

[0003] At present, during the running of the air conditioner, the user may manually adjust the guide vane in order to achieve the desired use effect, or the user may accidentally collide with the guide vane, causing the abnormal position or closing of the guide vane. It can be seen that the possibility of the air outlet guide vane being intentionally or unintentionally abnormally closed by human being exists. When the guide vane is in an abnormal position or closed, the air conditioning refrigeration system continues to run, which will cause the refrigeration or heating effect to be poor, and will also have a negative impact on the operation of the system. Especially when heating, if the upper air baffle is closed, the evaporator in the upper air duct actually functions as a condenser, and the closing of the guide vane will cause the system pressure to abnormally rise, thereby triggering a protection action or causing the compressor to stop, which is easy to cause the user's complaint. In addition, long-term operation in this way will also cause the system to run at high pressure, which will have a bad impact on the service life of the refrigeration system such as the compressor, evaporator and condenser, and shorten the service life of the air conditioner.

[0065] Reference is made to Figure 1Fig. 1 is a structural schematic diagram of an air conditioner in a first embodiment according to an embodiment of the present application. An air conditioner 10 according to an embodiment of the present application can be used to perform functions such as refrigeration, heating, and dehumidification. The air conditioner 10 has an indoor air outlet 11 for achieving an indoor air supply function. A damper 12 is provided at the air outlet 11 and is used to adjust the air supply direction of the air outlet 11.

[0066] The air conditioner 10 includes a refrigeration system 13, as shown in Fig. 2. Figure 2 Fig. 3 is a partial structural schematic diagram of a refrigerant circuit of the air conditioner according to an embodiment of the present application. The refrigeration system 13 is provided with a compressor 131, a condenser 132, an expansion valve 133, and an evaporator 134 connected to form a refrigerant circuit for circulating refrigerant. According to different operating modes of the air conditioner, one of the condenser 132 and the evaporator 134 is an outdoor heat exchanger, and the other is an indoor heat exchanger.

[0067] The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been adjusted and heat exchanged. The compressor 131 compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser 132. The condenser 132 condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve 133 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser 132 into low-pressure liquid-phase refrigerant. The evaporator 134 evaporates the refrigerant expanded in the expansion valve 133 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 131. The evaporator 134 can achieve a refrigeration effect by heat exchange with a material to be cooled using the latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of an indoor space.

[0068] In an alternative embodiment, the air conditioner is a split-type air conditioner, which can be provided in types such as a cabinet-type air conditioner and a wall-type air conditioner. The split-type air conditioner includes an indoor unit and an outdoor unit. For the split-type air conditioner, the indoor heat exchanger is generally provided in the indoor unit, the compressor 131 and the outdoor heat exchanger are generally provided in the outdoor unit, and the expansion valve 133 can be provided in the indoor unit or the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger are used as the condenser 132 or the evaporator 134. When the indoor heat exchanger is used as the condenser 132, the air conditioner is used as a heater in a heating mode. When the indoor heat exchanger is used as the evaporator 134, the air conditioner is used as a cooler in a refrigeration mode. Connection pipes are used to connect the indoor unit and the outdoor unit to form a refrigerant circuit for circulating refrigerant.

[0069] The shell of the indoor unit further comprises an indoor fan, an indoor air outlet 11, and a guide vane 12 for air guide control, which comprises a plurality of transverse guide vanes and / or longitudinal guide vanes. The indoor fan is configured to change the air volume when blowing out the conditioned air that has been heat-exchanged by the indoor heat exchanger, and the guide vane is configured to swing the blowing direction of the conditioned air blown out from the indoor fan, wherein the transverse guide vane is used to adjust the up-down blowing direction, and the longitudinal guide vane is used to adjust the left-right blowing direction. The outdoor unit further comprises an outdoor fan in addition to the compressor 131 and the outdoor heat exchanger, and the outdoor fan generates the airflow of the outdoor air through the outdoor heat exchanger to promote the heat exchange between the refrigerant flowing in the heat transfer pipe and the outdoor air.

[0070] In another embodiment, the air conditioner is a one-piece air conditioner, which only comprises an indoor unit compared with a split air conditioner, and the indoor unit integrates the air supply device such as the indoor air outlet 11 and the guide vane 12 and the refrigeration system such as the compressor 131, the condenser 132, the expansion valve 133, and the evaporator 134.

[0071] It should be noted that the specific structure and working principle of the indoor unit and the outdoor unit of the split air conditioner and the specific structure and working principle of the one-piece air conditioner can refer to the prior art, and will not be described here.

[0072] Further, the air conditioner 10 further comprises a controller 14, and for the split air conditioner, the controller 14 has an outdoor control device built in the outdoor unit and an indoor control device built in the indoor unit. The outdoor control device and the indoor control device are connected to each other by a signal line and can send / receive signals to each other, so as to realize the information acquisition and control instruction issuing of each component of the air conditioner and the like.

[0073] In the embodiment of the present application, referring to Figure 3 is a flowchart of the controller performing the work in the first embodiment, and the controller 14 is specifically used to execute steps S11 to S14:

[0074] S11, after the air conditioner is powered on and runs, the running parameters of the air conditioner are acquired in real time;

[0075] S12, every first preset time length, whether the swing position of the guide vane is abnormal is detected according to the running parameters, and the number of times of abnormal results is accumulated;

[0076] S13, when the accumulated number of times of abnormal results reaches a first number threshold, a correction action of the guide vane is performed, the accumulated number of times of abnormal results is cleared, and the number of times of performing the correction action is accumulated;

[0077] S14, when the cumulative execution number of the correction action reaches a second number threshold, performing a preset alarm action, and clearing the cumulative execution number of the correction action.

[0078] In the embodiment of the present application, after the air conditioner 10 is powered on, in the running process, the first preset time length t1 is taken as a detection period, the current running parameter of the air conditioner 10 is obtained to determine whether the swing position of the air deflector is abnormal.

[0079] It should be noted that the first preset time length t1 is a preset value, and its specific value can be set to 1 minute or 2 minutes, of course, it can also be set to other values according to actual conditions, and does not constitute a limitation on the present application.

[0080] Specifically, after the air conditioner 10 is powered on and runs, the running parameter of the air conditioner 10 is obtained, the current running parameter of the air conditioner 10 is used to determine whether the swing position of the air deflector 12 is abnormal, if the swing position of the air deflector 12 is determined to be normal, the air conditioner continues to run according to the current running state; if the swing position of the air deflector 12 is determined to be abnormal, in order to avoid misjudgment, the controller 14 sets and maintains the cumulative number N of abnormal results, and when the abnormal result is obtained, the cumulative number N of abnormal results is incremented by one, and the air conditioner continues to run according to the current running state for a first preset time length t1, the current running parameter of the air conditioner 10 is obtained again, and whether the swing position of the air deflector 12 is abnormal is determined according to the current running parameter of the air conditioner 10. Through such periodic cyclic collection and detection, if an abnormal result is obtained, the cumulative number N is incremented by one, and when the cumulative number N reaches a preset first number threshold Ns, it is indicated that the swing position of the air deflector 12 is indeed abnormal, and a correction action of the air deflector is performed, and the cumulative number N of abnormal results is cleared. And the controller 14 sets and maintains the cumulative execution number M of the correction action, and increments the cumulative execution number M of the correction action by one each time the correction action is executed. Then the air conditioner continues to run according to the current running state for a first preset time length t1, the current running parameter of the air conditioner 10 is obtained again, and whether the swing position of the air deflector 12 is abnormal is determined according to the current running parameter of the air conditioner 10. In this way, the cycle is repeated. When the cumulative execution number M of the correction action reaches a preset second number threshold Ms, it is indicated that the air deflector 12 cannot run normally after multiple correction actions, and it is confirmed that the air deflector is in an abnormal state, which may be caused by human factors to cause the air deflector to be stuck and unable to be corrected, or it may be a drive motor fault of the air deflector. In short, if it continues to run in this state, it will have an adverse effect on the air conditioner system and even may have a security risk, so it is determined that it is a problem of the whole machine at this time, a preset alarm action is performed to remind the user to manually eliminate the fault factors of the air deflector, and the cumulative execution number M of the correction action is cleared.

[0081] Preferably, the first number threshold value Ns and the second number threshold value Ms are preset values, which can be determined according to the actual operation of the air conditioner product, and optionally, the first number threshold value Ns is set to 4-7 times, for example, 4 times, 5 times or 7 times, and the second number threshold value Ms is set to 4-7 times, for example, 4 times, 5 times or 7 times.

[0082] Preferably, the air conditioner is provided with an alarm device, and the execution of the preset alarm action specifically refers to controlling the alarm device to perform a preset alarm operation.

[0083] The alarm device can be configured as a display screen to complete the alarm operation by displaying corresponding text, icons, etc.; the alarm device can also be configured as a voice module to complete the alarm operation by playing corresponding voice; the alarm device can also be configured as an LED lamp group module to complete the alarm operation by lighting the LED lamp group, changing its color or flicker frequency, etc.; the alarm device can also be configured as a buzzer to complete the alarm operation by emitting a whistle sound. Of course, the alarm device can also be other alarm modes, or a combination of any two or more of the above modes, without affecting the beneficial effects achieved by the present application.

[0084] By using the technical means of the embodiment of the present application, the swing position of the air deflector is analyzed and judged to be abnormal or not through real-time collection of the operating parameters of the air conditioner, so that corresponding correction or alarm measures can be taken in time. The number of times of abnormal results is accumulated through multiple small period judgments, in order to more stably and accurately judge the abnormal state of the air deflector and avoid the influence of fluctuation factors; then the number of execution times of the correction action after the air deflector abnormality judgment is also accumulated, which is to make the air deflector recover to normal as much as possible after multiple corrections; and the alarm action is performed after the accumulated execution number of the air deflector correction action reaches the preset value, which is to remind the user to handle the human factors. That is, through the cycle and accumulation of air deflector abnormality judgment by reading the operating parameters, the execution and accumulation of air deflector correction action, and the triggering of alarm action and a series of operations, the air deflector fault operation problem can be automatically and effectively identified and solved, so that the air deflector of the air conditioner runs at a normal angle, the air outlet is smoother, the normal operation of the air conditioner is ensured, the comfort of product use is improved, the service life of the product is also increased, and finally the user's air conditioner use experience is effectively improved.

[0085] Preferably, referring to Figure 4 is a flowchart of the controller executing work in the second embodiment, and the controller 14 is further used to execute step S15:

[0086] S15, after executing the preset alarm action and after a second preset time length, if it is determined that the swing position of the deflector is still an abnormal result, the air conditioner is controlled to be turned off.

[0087] Specifically, the second preset time length t2 is a pre-set waiting time value, and a specific value thereof can be set according to actual conditions, and does not constitute a limitation to the present application, for example, the second preset time length t2 is set to 5 minutes.

[0088] In the embodiment of the present application, after the controller 14 triggers the execution of the alarm action, a second preset time length t2 is waited for, for waiting for a user to handle the failure of the deflector, because if an object is stuck or pressed on the deflector due to human factors, a person must come to handle and remove it, such as removing the object stuck on the deflector or removing the object such as a book pressed on the deflector to cause the deflector to close. After the second preset time length t2, the current running parameters of the air conditioner are acquired again to determine whether the swing position of the deflector is abnormal, and if it is not restored to normal, it indicates that there is no user to handle or it cannot be handled, and the air conditioner is controlled to be turned off.

[0089] By using the technical means of the embodiment of the present application, after triggering the alarm action, a certain waiting time is reserved to wait for manual processing, and when the deflector is still abnormal after the waiting time, the whole machine is controlled to be stopped, thereby avoiding the continuous running of the air conditioner in the abnormal state of the deflector to cause the wear and tear or safety problem of the air conditioner, and improving the safety of the air conditioner running.

[0090] Preferably, after the air conditioner is powered on and runs, the running parameters of the air conditioner are acquired in real time, specifically:

[0091] After the air conditioner is powered on and runs for a third preset time length, the running parameters of the air conditioner are acquired in real time.

[0092] Specifically, the third preset time length refers to the time required for the air conditioner to run to a stable state, and the embodiment of the present application executes the operation of acquiring the running parameters of the air conditioner after the air conditioner is powered on and runs for a third preset time length t3, and the running state of the air conditioner reaches stability.

[0093] By using the technical means of the embodiment of the present application, the problem that the system is not stable and balanced at the initial stage of starting the air conditioner, and the running parameters of the air conditioner are not stable at this time, which causes errors in the evaluation of whether the swing position of the deflector is abnormal, can be avoided, and the judgment accuracy of the swing position of the deflector is improved.

[0094] As a preferred embodiment, the running parameters of the air conditioner include the coil temperature of the condenser and the coil temperature of the evaporator.

[0095] See Figure 5is a flowchart of the controller in the third embodiment of the present application, and the step S12 includes the following step S121:

[0096] S121, determining whether the coil temperature of the condenser and the coil temperature of the evaporator meet the preset temperature reference value requirement.

[0097] S122, if yes, obtaining a result that the swing position of the air deflector is normal, and if no, obtaining a result that the swing position of the air deflector is abnormal.

[0098] The coil temperature of the condenser 132 and the coil temperature of the evaporator 134 change with the running state of the air conditioner, and are also affected by the swing position of the air deflector. For example, when the air deflector 12 is abnormally closed and the air conditioner continues to run, the coil temperature of the condenser or the evaporator abnormally increases or decreases. Therefore, in the embodiment of the present application, whether the swing position of the air deflector 12 is abnormal is determined by determining whether the coil temperature T1r of the condenser 132 and the coil temperature T2r of the evaporator 134 meet the preset temperature reference value requirement.

[0099] Specifically, the preset temperature reference value requirement includes a first coil temperature reference value T1s corresponding to the condenser 132 and a second coil temperature reference value T2s corresponding to the evaporator 134. When the coil temperature T1r of the condenser 132 is consistent or similar to the first coil temperature reference value T1s, and the coil temperature T2r of the condenser 132 is consistent or similar to the second coil temperature reference value T2s, it is considered that the coil temperatures of the condenser 132 and the evaporator 134 meet the preset temperature reference value requirement.

[0100] As a preferred embodiment, the first coil temperature reference value T1s corresponding to the condenser 132 and the second coil temperature reference value T2s corresponding to the evaporator 134 are closely related to the current running state of the air conditioner. The embodiment of the present application optimizes and explains the acquisition method of the first coil temperature reference value T1s corresponding to the condenser 132 and the second coil temperature reference value T2s corresponding to the evaporator 134.

[0101] Referring to Figure 6 is a structural schematic diagram of the air conditioner in the second embodiment of the present application, and the air conditioner further includes an environment parameter sensor 15 for collecting the environment parameters of the indoor environment where the air conditioner is located. The environment parameter refers to the environment parameter that has an influence on the running state of the air conditioner. The controller 14 is connected with the environment parameter sensor 15, and is used for receiving the environment parameters collected by the environment parameter sensor 15.

[0102] Referring to Figure 7is a flowchart of the controller in the fourth embodiment of the present application, step S121, that is, whether the condenser coil temperature and the evaporator coil temperature meet the preset temperature reference value requirement, specifically:

[0103] According to the environmental parameter and the current setting wind speed of the air conditioner, the first coil temperature reference value corresponding to the condenser and the second coil temperature reference value corresponding to the evaporator are determined;

[0104] The difference between the condenser coil temperature and the first coil temperature reference value is calculated as the first coil temperature difference value;

[0105] The difference between the evaporator coil temperature and the second coil temperature reference value is calculated as the second coil temperature difference value;

[0106] When the first coil temperature difference value is less than the preset first coil temperature tolerance value, and the second coil temperature difference value is less than the preset second coil temperature tolerance value, it is determined that the condenser coil temperature and the evaporator coil temperature meet the preset temperature reference value requirement.

[0107] As an example, the environmental parameter can be the environmental temperature, and the environmental parameter sensor can be configured as an environmental temperature sensor for collecting the environmental temperature T3 of the indoor environment where the air conditioner is located, and / or the environmental parameter can be the environmental relative humidity, and the environmental parameter sensor can be configured as an environmental relative humidity sensor for collecting the environmental relative humidity RH of the indoor environment where the air conditioner is located. Of course, the environmental parameter can also be other environmental parameters that have an impact on the running state of the air conditioner, and the sensor is set according to the actual situation to obtain, which does not constitute a limitation on the present application.

[0108] In addition, the air conditioner is provided with a plurality of wind speeds W in advance, and the rotational speed of the indoor fan corresponding to different wind speeds is different. As an example, the wind speed of the air conditioner includes high wind speed W1, medium wind speed W2 and low wind speed W3, wherein the rotational speed of the fan corresponding to high wind speed W1, medium wind speed W2 and low wind speed W3 decreases in turn.

[0109] In the embodiment of the present application, by obtaining the environmental parameter of the indoor environment where the air conditioner is located and the current setting wind speed W of the air conditioner, the current running state of the air conditioner is judged, so that the first coil temperature reference value T1s required by the condenser 132 under the current running state is determined, for example, 10℃, and the second coil temperature reference value T2s required by the evaporator 134 is determined, for example, 45℃.

[0110] And, a first coil temperature tolerance value Cs1 is set in advance to represent the difference between the actual coil temperature T1r of the condenser 132 and the corresponding first coil temperature reference value T1s, and a second coil temperature tolerance value Cs2 is set in advance to represent the difference between the actual coil temperature T2r of the evaporator 134 and the corresponding second coil temperature reference value T2s.

[0111] Preferably, the first coil temperature tolerance value Cs1 and the second coil temperature tolerance value Cs2 are preset values, which can be determined according to the actual operation of the air conditioner product. Optionally, the first coil temperature tolerance value Cs1 is set to 0-2℃, for example, 0℃ or 2℃, and the second coil temperature tolerance value Cs2 is set to 0-2℃, for example, 0℃ or 2℃.

[0112] Further, the difference between the coil temperature T1r of the condenser and the first coil temperature reference value T1s is calculated as a first coil temperature difference AT1 = |T1r-T1s|, and the first coil temperature difference AT1 is compared with the first coil temperature tolerance value Cs1. Similarly, the difference between the coil temperature T2r of the evaporator and the second coil temperature reference value T2s is calculated as a second coil temperature difference AT2 = |T2r-T2s|, and the second coil temperature difference AT2 is compared with the second coil temperature tolerance value Cs2.

[0113] When AT1 < Cs1 and AT2 < Cs2 are satisfied, it indicates that the actual coil temperature T1r of the condenser and the corresponding reference temperature T1s are not greatly different, and the actual coil temperature T2r of the evaporator and the corresponding reference temperature T2s are not greatly different, and it is determined that the coil temperature of the condenser and the coil temperature of the evaporator satisfy the preset temperature reference value requirement. At this time, it is recognized that the running state of the air conditioner is normal, and the swing position of the deflector is also normal.

[0114] As a preferred embodiment, the environmental parameters include an environmental temperature T3 and an environmental relative humidity RH. The corresponding first coil temperature reference value of the condenser and the corresponding second coil temperature reference value of the evaporator are determined according to the environmental parameters and the current set air volume of the air conditioner, specifically:

[0115] The corresponding first coil temperature reference value of the condenser and the corresponding second coil temperature reference value of the evaporator are calculated according to the environmental temperature, the environmental relative humidity and the current set air volume of the air conditioner.

[0116] In the embodiment of the present application, the coil temperatures of the condenser 132 and the evaporator 134 under different environmental temperature T3, environmental relative humidity RH and wind stop W are determined when the swing position of the air deflector 12 of the air conditioner is in the normal position through multiple tests and experiments, so as to determine the corresponding relationship between the different environmental temperature T3, environmental relative humidity RH, wind stop W and the coil temperature reference values of the condenser 132 and the evaporator 134, form a database for storage, so as to facilitate the query and call of the controller.

[0117] In the actual application process, after the controller 14 obtains the current environmental temperature T3, environmental relative humidity RH and wind stop W, the coil temperature reference values of the condenser 132 and the evaporator 134, that is, the first coil temperature reference value T1s and the second coil temperature reference value T2s, can be obtained.

[0118] Referring to Figure 8 is a flow diagram of the controller in the fifth embodiment of the present application. After the air conditioner is powered on and runs for a third preset time t3, the air conditioner system reaches a stable state, the current environmental temperature T3, relative humidity RH and the current wind stop state W are obtained, the first coil temperature reference value T1s corresponding to the condenser and the second coil temperature reference value T2s corresponding to the evaporator are obtained by comprehensively adjusting the preset database according to the three parameters, the actual coil temperature T1r of the condenser and the actual coil temperature T2r of the evaporator are obtained, and then it is judged whether ΔT1=|T1s-T1r| is less than the first preset coil temperature tolerance value Cs1 and whether ΔT2=|T2s-T2r| is less than the second preset coil temperature tolerance value Cs2. If both are true, the air conditioner continues to run, if ΔT1≥Cs1 or ΔT2≥Cs2, the abnormal result is determined, the cumulative number N of abnormal results is increased by 1, and then the air conditioner continues to run for a first preset time t1 and enters the next detection period, and returns to the previous detection and judgment step. In this way, through periodic cyclic collection, the cumulative number N of abnormal results is increased by 1, that is, N=N+1, when the cumulative number N of abnormal results reaches a first number threshold Ns, a correction action of the air deflector is performed, the cumulative number N is cleared, and the cumulative execution number M of the correction action is increased by 1, that is, M=M+1. When the cumulative execution number M reaches a second number threshold Ms, it is indicated that the air deflector cannot run normally after multiple resets, and an alarm action is performed, the display light flashes, the buzzer sounds, and the like, and the cumulative execution number M is cleared. After a waiting time, that is, a second preset time t2, ΔT1 and ΔT2 are calculated again, and the relationship with the corresponding tolerance value Cs is judged. If it is still not normal, it is indicated that there is no user to handle or handle, and the air conditioner is shut down, and a fault code is displayed.

[0119] By means of the technical means of the embodiment of the present application, the evaporator and condenser coil temperature reference values are read from the pre-stored database through the detection of the environmental parameters and the detection of the set air volume of the air conditioner, and then the measured values of the condenser and evaporator coil temperatures are compared with the coil temperature reference values for analysis to determine whether the state of the air deflector is abnormal. The abnormal state of the air deflector is determined more stably and accurately through multiple small period determinations and accumulation of the number of abnormal results to avoid the influence of fluctuation factors. Furthermore, the number of execution times of the correction action performed after the air deflector abnormality determination is also accumulated, which is to make the air deflector recover to normal as much as possible after multiple corrections. Furthermore, the alarm action is performed after the accumulated execution number of the air deflector correction action reaches the preset value, which is to remind the user to handle the human factors. That is, the present application can automatically and effectively identify and solve the fault operation problem of the air deflector through the cycle and accumulation of the air deflector abnormality determination by reading the operating parameters, the execution and accumulation of the air deflector correction action, and a series of operations such as triggering the alarm action, so that the air deflector of the air conditioner runs at a normal angle, the air outlet is smoother, the normal operation of the air conditioner is ensured, the comfort of product use is improved, the service life of the product is also increased, and the user's air conditioner use experience is ultimately effectively improved.
