[0033] In the embodiments, a control method of an air conditioner operation running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown.
[0034] Figure 2 is a flowchart of the control method of the air conditioner operation according to the embodiments of the present application. As shown in Figure 2 , the method includes the following steps:
[0035] In step S201, at the start time of the heating function of the air conditioner, the outdoor environment temperature and the indoor environment temperature of the air conditioner are acquired.
[0036] The outdoor environment temperature of the air conditioner is generally constant within a period of time, for example, constant within 20 minutes or constant within 30 minutes. The indoor environment temperature of the air conditioner changes with the start of the heating function of the air conditioner. Therefore, the outdoor environment temperature and the indoor environment temperature of the air conditioner are acquired at the start of the heating function of the air conditioner, which is helpful for accurately determining the preset stay duration of the stay stage of the compressor and the frequency of the stay stage of the compressor in the subsequent process.
[0037] In step S202, a preset stay duration of the stay stage of the compressor of the air conditioner is determined according to the outdoor environment temperature, and a stay stage frequency of the compressor is determined according to the outdoor environment temperature and the indoor environment temperature, wherein the operating frequency of the compressor remains unchanged when in the stay stage;
[0038] For example, the preset stay duration of the stay stage of the compressor is 0s, 30s, 120s, etc., and the stay stage frequency of the compressor is 56Hz, 66Hz, 70Hz, etc.
[0039] In the existing scheme, the preset stay duration of the stay stage and the stay stage frequency are set as fixed values, without considering the outdoor environment temperature and the indoor environment temperature, whereas the cold-blast prevention control is related to the indoor and outdoor environment temperatures and the state of the air conditioning system. This fixed value setting mode is prone to cause the following situation: when the air conditioner reaches the exit condition of the cold-blast prevention control under some low-temperature working conditions, the compressor has just entered or is in the frequency stay stage, at this time, the air conditioner is normally operated in the heating mode, the outlet air temperature rapidly decreases, and cold-blast heating occurs, which cannot achieve the expected cold-blast prevention effect. In the scheme of the present application, the indoor and outdoor environment temperatures are considered when setting the preset stay duration and the stay stage frequency, thereby avoiding the above-mentioned situation.
[0040] In step S203, after the start time, the inner tube temperature of the air conditioner is acquired in real time, and in the case that the inner tube temperature of the air conditioner is greater than or equal to the preset tube temperature, whether to control the compressor to exit the cold-blast prevention control mode is determined according to the first cumulative operating duration of the compressor, the preset duration, and the target duration.
[0041] That is, after the heating function of the air conditioner is started, the inner tube temperature of the air conditioner is acquired in real time, that is, the size relationship between the inner tube temperature of the air conditioner and the preset tube temperature is dynamically compared, and in the case that the inner tube temperature of the air conditioner is greater than or equal to the preset tube temperature, it is indicated that the inner tube temperature of the air conditioner at this time is high, and the cold-blast prevention control mode can be prepared to be exited.
[0042] The target duration is the sum of the second cumulative operating duration and the preset stay duration, the second cumulative operating duration is associated with the stay stage frequency, and the first cumulative operating duration is the cumulative duration from the start time to the current time, and the second cumulative operating duration is the cumulative duration from the start time to the initial time when the compressor enters the stay stage.
[0043] In the scheme of the present application, the second cumulative operating duration is associated with the stay stage frequency, which means that whether to control the compressor to exit the cold-blast prevention control mode needs to consider the stay stage frequency, and the stay stage frequency is a key factor for improving the control function of oil return of the compressor, so that the coupling of the control function of oil return of the compressor and the cold-blast prevention control function of heating is achieved.
[0044] The control method for air conditioner operation of the application, by acquiring the outdoor environment temperature and the indoor environment temperature of the air conditioner at the opening moment of the heating function of the air conditioner, determining the preset stay duration of the stay stage of the compressor of the air conditioner according to the outdoor environment temperature, determining the stay stage frequency of the compressor according to the outdoor environment temperature and the indoor environment temperature, and acquiring the inner tube temperature of the air conditioner in real time after the opening moment, and in the case that the inner tube temperature of the air conditioner is greater than or equal to the preset tube temperature, determining whether to control the compressor to exit the anti-cold wind control mode according to the first cumulative running duration of the compressor, the preset duration and the target duration. The coupling of the control function of improving the oil return of the compressor and the heating anti-cold wind control function is realized. The problem that the existing processing method cannot achieve the expected anti-cold wind effect is solved. The heating comfort and the operation reliability are taken into account.
[0045] In some specific schemes, the step S202 of determining the preset stay duration of the stay stage of the compressor of the air conditioner according to the outdoor environment temperature is specifically implemented as:
[0046] In the case that the outdoor environment temperature is less than the first preset outdoor environment temperature, the preset stay duration is determined as the first preset stay duration;
[0047] In the case that the outdoor environment temperature is greater than or equal to the first preset outdoor environment temperature and less than or equal to the second preset outdoor environment temperature, the preset stay duration is determined as the second preset stay duration;
[0048] In the case that the outdoor environment temperature is greater than the second preset outdoor environment temperature, the preset stay duration is determined as the third preset stay duration, wherein the first preset outdoor environment temperature is less than the second preset outdoor environment temperature, the first preset stay duration is greater than the second preset stay duration, and the second preset stay duration is greater than the third preset stay duration.
[0049] For example, the first preset outdoor environment temperature is valued at-7℃, the second preset outdoor environment temperature is valued at 18℃, and the first preset stay duration, the second preset stay duration and the third preset stay duration are respectively valued at: 120s, 30s and 0s. Of course, such values are only exemplary.
[0050] In some specific schemes, the step S202 of determining the stay stage frequency of the compressor according to the outdoor environment temperature and the indoor environment temperature includes:
[0051] Step S2021: acquiring the temperature difference between the indoor environment temperature and the outdoor environment temperature;
[0052] Step S2022: determining the stay stage frequency of the compressor according to the temperature difference and the outdoor environment temperature, wherein the stay stage frequency decreases with the decrease of the outdoor environment temperature, and the stay stage frequency decreases with the increase of the temperature difference. That is, the lower the outdoor environment temperature, the smaller the stay stage frequency is set to be, and the greater the temperature difference indicates the lower the outdoor environment temperature, and the stay stage frequency is also set to be lower. Such setting can achieve the expected cold wind prevention effect.
[0053] Specifically, according to the relationship F1=c2×Tw+c3×ΔT+c4, wherein F1 is the stay stage frequency, c2 is the second coefficient, c3 is the third coefficient, c4 is a constant, and ΔT is the temperature difference. Specifically, the values of c2, c3 and c4 are different for different models. For example, for a certain 3P cabinet air conditioner, c2=0.39, c3=0.0387, and c4=66.5.
[0054] In the method embodiment of the present application, step S2022: determining the stay stage frequency of the compressor according to the temperature difference and the outdoor environment temperature, comprises:
[0055] determining the initial stay stage frequency of the compressor according to the temperature difference and the outdoor environment temperature;
[0056] in the case that the initial stay stage frequency is less than the preset minimum frequency, determining the preset minimum frequency as the final stay stage frequency;
[0057] in the case that the initial stay stage frequency is greater than the preset maximum frequency, determining the preset maximum frequency as the final stay stage frequency.
[0058] That is, the stay stage frequency of the compressor determined according to the relationship F1=c2×Tw+c3×ΔT+c4 may be too small or too large, and in these cases, the preset minimum frequency needs to be set to limit the lower limit value, so as to avoid the slow oil return rate of the compressor leading to the decrease of the reliability of the air conditioner.
[0059] The preset maximum frequency needs to be set to limit the upper limit value, so as to avoid the high oil discharge rate of the compressor leading to the oil shortage or empty oil of the system, and to protect the operation reliability of the air conditioner. Thus, the expected cold wind prevention effect can be achieved.
[0060] In the method embodiment of the present application, before determining whether to control the compressor to exit the cold wind prevention control mode according to the first cumulative running time of the compressor, the preset time length and the target time length, the method further comprises:
[0061] obtaining the starting initial frequency and the frequency increasing rate of the compressor;
[0062] The second cumulative running time is determined according to the start initial frequency, the stay stage frequency, the frequency increasing rate and the additional time length, wherein the additional time length comprises a compressor standby time length and a compressor start protection time length.
[0063] Specifically, the second cumulative running time s1 is determined according to the relationship: s1 = (F1-Fstart) / v+s other The second cumulative running time s1 is determined according to the relationship: s1 = (F1-Fstart) / v+s other The additional time length comprises various compressor start protection time lengths. The various compressor start protection time lengths comprise a compressor start time of about 9s, a compressor AC current / module current / overload limited frequency reduction protection time (obtained by monitoring).
[0064] In the method embodiment of the application, in the case that the inner tube temperature of the air conditioner is greater than or equal to the preset tube temperature, whether to control the compressor to exit the cold wind prevention control mode is determined according to the first cumulative running time of the compressor, the preset time length and the target time length, comprising:
[0065] In the case that the first cumulative running time is less than or equal to the preset time length, the compressor is controlled to exit the cold wind prevention control mode.
[0066] Specifically, the preset time length can be set to 170s, 200s or 290s.
[0067] That is, in the case that the first cumulative running time is less than or equal to the preset time length, it is indicated that the current room working condition temperature is high, the load is small and the temperature rising rate is fast, and it is not easy to blow cold wind, so the cold wind prevention control is exited and the inner fan is improved to the normal rotating speed.
[0068] In the case that the first cumulative running time is greater than the preset time length and less than or equal to the target time length, whether to control the compressor to exit the cold wind prevention control mode is determined according to the current frequency of the compressor and the stay stage frequency after the rotating speed of the inner fan of the air conditioner is kept unchanged or slowly improved for a preset time period.
[0069] That is, in the case that the first cumulative running time is greater than the preset time length and less than or equal to the target time length, it is indicated that the air conditioner reaches the target inner tube temperature condition for exiting the cold wind prevention, and just enters or is in the compressor frequency stay control stage, so the cold wind prevention control is exited to cause the inner tube temperature and the outlet air temperature to rapidly decrease, and therefore the rotating speed of the inner fan of the air conditioner is kept unchanged or slowly improved for a preset time period to maintain the inner tube temperature between T±2℃, and the relationship between the current frequency of the compressor and the stay stage frequency is continuously determined.
[0070] Step S2033: In the case that the first accumulated running duration is greater than the preset duration and greater than the target duration, the compressor is controlled to exit the cold-blast prevention control mode.
[0071] That is, in the case that the first accumulated running duration is greater than the preset duration and greater than the target duration, it is indicated that the air conditioner is in the compressor frequency increasing stage, and then the cold-blast prevention control is exited, and the inner fan is increased to the normal rotating speed.
[0072] In the method embodiment of the present application, whether the compressor is controlled to exit the cold-blast prevention control mode is determined according to the current frequency of the compressor and the frequency in the staying stage, comprising:
[0073] In the case that the current frequency of the compressor is greater than the frequency in the staying stage, the compressor is controlled to exit the cold-blast prevention control mode;
[0074] That is, in the case that the current frequency of the compressor is greater than the frequency in the staying stage, it is indicated that the air conditioner enters the compressor frequency increasing stage, and then the cold-blast prevention control is exited, and the inner fan is increased to the normal rotating speed.
[0075] In the case that the current frequency of the compressor is less than or equal to the frequency in the staying stage, the inner fan rotating speed is controlled to maintain the inner pipe temperature of the air conditioner, so that the compressor does not exit the cold-blast prevention control mode.
[0076] That is, in the case that the current frequency of the compressor is less than or equal to the frequency in the staying stage, it is indicated that the air conditioner is still in the frequency staying control stage, and then the inner fan rotating speed is controlled to maintain the inner pipe temperature of the air conditioner, so that the cold-blast prevention control mode is prevented from being exited.
[0077] In some schemes, the method further comprises: after the starting moment, the inner pipe temperature of the air conditioner is acquired in real time, and in the case that the inner pipe temperature of the air conditioner is less than the preset pipe temperature, the inner fan of the air conditioner is controlled to maintain the current running state. That is, in the case that the inner pipe temperature of the air conditioner is less than the preset pipe temperature, it is not necessary to determine whether the cold-blast prevention control mode is exited, and the inner fan of the air conditioner is controlled to maintain the current running state.
[0078] In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, the implementation process of the air conditioner running control method of the present application will be described in detail below in combination with specific embodiments.
[0079] The present embodiment relates to a specific air conditioner running control method, as shown in Figure 3 , comprising:
[0080] When the air conditioner is started to run in heating mode, the outdoor environment temperature T w , the indoor environment temperature T n is detected and recorded, and the temperature difference ΔT=T n -T w is calculated. According to the outdoor environment temperature T w, the temperature difference ΔT determines the compressor stay stage frequency F1, the preset stay duration t, wherein,
[0081] F1=c2×Tw+c3×ΔT+c4,
[0082] ① When Tw
[0083] ② When A≤Tw≤B, the preset stay duration is t2
[0084] ③ When Tw
[0085] For example, A=-7℃, B=18℃, t1, t2, t3 are 120s, 30s, 0s respectively
[0086] Wherein, F1 is the stay stage frequency, c2 is the second coefficient, c3 is the third coefficient, c4 is the constant, ΔT is the temperature difference, Tw is the outdoor environment temperature, A is the first preset outdoor environment temperature, B is the second preset outdoor environment temperature.
[0087] When the outdoor environment temperature T w is lower, the temperature difference ΔT is larger, the system oil return state is poor, then the compressor stay stage frequency F1 is lower, the stay time t is longer, the compressor oil discharge rate is lower, the oil return time is longer, and the system oil return is improved. Determine the relationship between F1 and the preset minimum value F min , when F1 min is less than F min , F1 takes F w , to avoid slow compressor oil return rate leading to air conditioner reliability decline.
[0088] When the outdoor environment temperature T w is higher, the temperature difference ΔT is smaller, the system oil return state is good, then the compressor stay stage frequency F1 is higher, the stay time t is shorter, the heating output is more, and the indoor temperature rise rate is improved. Determine the relationship between F1 and the preset maximum value F max , when F1 max is greater than F max , F1 takes F other , to avoid too high compressor oil discharge rate leading to system oil shortage or empty oil, and to protect air conditioner operation reliability.
[0089] Continue to obtain the compressor frequency increase rate v, calculate the compressor cumulative running time s1 when the compressor enters the frequency stay control, and the calculation formula is as follows:
[0090] s1=(F1-Fstart) / v+s other ;
[0091] Wherein, s1 is the second cumulative running time (i.e. the cumulative running time of the compressor when entering the frequency stay control), F1 is the frequency in the stay stage, Fstart is the initial start frequency, v is the frequency increasing rate, s other is the additional time length;
[0092] When the air conditioner is started in the heating operation mode, the indoor fan of the air conditioner is closed or maintained at a low speed operation, and the real-time detection and recording of the tube temperature T s inside the indoor heat exchanger of the air conditioner are performed. s Firstly, the relationship between the tube temperature T
[0093] 1) If T s is less than T1, i.e. the tube temperature inside the air conditioner is low, and the outlet air temperature of the air conditioner is low, the current state of the indoor fan being closed or running at a low speed is maintained to prevent cold air from being directly blown;
[0094] 1) If T s is greater than or equal to T1, i.e. the tube temperature inside the air conditioner is relatively high, the cumulative running time s of the compressor is recorded, and the relationship between the cumulative running time (i.e. the first cumulative running time) s of the compressor and the preset time length s0 and the cumulative running time s1 of the entering stay point is determined.
[0095] i If s is less than or equal to s0, i.e. the room working condition temperature is high, the load is small, and the temperature rising rate is fast, and it is not easy to blow cold air, the cold air prevention control is exited, and the indoor fan is increased to a normal speed operation;
[0096] ii If s is greater than s0 and less than (s1+t), i.e. the air conditioner reaches the target tube temperature condition for exiting the cold air prevention, and just enters or is in the compressor frequency stay control stage, the indoor fan speed is slowly increased to maintain the tube temperature between T1±2℃, and the relationship between the compressor frequency F and the stay stage frequency F1 is determined,
[0097] a If F is less than or equal to F1, i.e. the air conditioner is still in the frequency stay control stage, the indoor fan speed is continuously controlled to maintain the tube temperature;
[0098] b If F is greater than F1, i.e. the air conditioner enters the compressor frequency increasing stage, the cold air prevention control is exited, and the indoor fan is increased to a normal speed operation;
[0099] iii If s is greater than (s1+t), i.e. the air conditioner is in the compressor frequency increasing stage, the cold air prevention control is exited, and the indoor fan is increased to a normal speed operation.
[0100] After the above air conditioner operation control method is adopted, the cold air blowing of the air conditioner in the heating operation mode can be avoided under the premise of ensuring the reliability of the air conditioner. Figure 4As shown, the air conditioner is in the condition of 0℃ inside and -5℃ outside, and the prior art scheme enters the frequency stay control after the compressor accumulates running for 160s, and exits the air conditioner anti-cold wind at the 190s, at this time, the air damper increases, the frequency remains unchanged, the inner tube temperature rapidly decreases from 40℃ to 28℃, and the outlet air temperature is as low as 18℃-20℃, the outlet air temperature is low; and the scheme of the application continues to maintain the anti-cold wind control after the air conditioner exits the frequency stay control, and exits the anti-cold wind control function until the 4min, compared with the prior art, the inner tube temperature of the scheme of the application is higher and will not fluctuate greatly.
[0101] As shown in Figure 5 , Figure 6 Compared with the prior art, the outlet air temperature of the patent scheme of the application is higher, the indoor temperature rise rate is faster, the outlet air temperature is increased by 5℃ in the first 15min of operation, the indoor temperature rise rate is increased by 9.2%, and the heating operation comfort of the air conditioner is effectively improved.
[0102] The scheme of the application solves the problem that the existing air conditioner still blows cold wind after exiting the anti-cold wind control in heating, realizes reliable and comfortable operation of the air conditioner, and improves the user experience. Due to the use of the air conditioner operation control method of the application, the compressor, the inner fan and other loads are accurately controlled when the air conditioner exits the anti-cold wind function, the negative influence of the frequency stay control of the air conditioner on the anti-cold wind control effect is solved, the air conditioner is reliably operated, the air conditioner still blows cold wind after exiting the anti-cold wind control is avoided, and the heating comfort of the user is improved.
[0103] The scheme of the application determines the compressor frequency of the air conditioner frequency stay control, the entering / exit time of constant frequency operation according to the indoor and outdoor environment temperature during heating operation, determines the first time of the air conditioner exiting the anti-cold wind through monitoring the inner tube temperature change, compares the entering / exit time of the constant frequency operation, adjusts the actual time of the air conditioner exiting the anti-cold wind, and controls the inner fan speed to be increased, so as to ensure a high outlet air temperature, avoid cold wind blowing in heating, and improve the heating comfort.

That is, the preset stay duration increases with the decrease of the outdoor environment temperature. That is, the longer the preset stay duration is, the lower the outdoor environment temperature is. This setting can achieve the expected anti-cold wind effect.
[0114] In the device embodiment of the application, the first determination unit comprises an acquisition module and a second determination module, the acquisition module is configured to acquire the temperature difference between the indoor environment temperature and the outdoor environment temperature, and the second determination module is configured to determine the stay stage frequency of the compressor according to the temperature difference and the outdoor environment temperature, wherein the stay stage frequency decreases with the decrease of the outdoor environment temperature, and the stay stage frequency decreases with the increase of the temperature difference.

At this time, exiting the cold-blast prevention control will cause the inner tube temperature and the air outlet temperature to rapidly decrease, so the rotating speed of the indoor fan of the air conditioner is controlled to remain unchanged or slowly increase for a preset time period to maintain the inner tube temperature between T±2℃, and the relationship between the current frequency of the compressor and the frequency of the staying stage is continuously determined. That is, when the first accumulated running duration is greater than the preset duration and greater than the target duration, it indicates that the air conditioner is in the compressor frequency increasing stage, so the cold-blast prevention control is exited, and the indoor fan is increased to the normal rotating speed.
