Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a control method, device, equipment and storage medium for an air conditioner. Background Art

[0002] The thermostat outputs 24V switch quantity to the 24V controller to control the air conditioning cooling, heating mode, air supply mode and shutdown mode, and then controls the compressor to turn on and off. In the related art, the 24V controller is connected from the indoor unit side. The set temperature range of the indoor unit is usually 17-30°C, while the set temperature range of the thermostat may exceed the range of 17-30°C, such as 10-35°C. In other words, the set temperature range of the indoor unit is smaller than the set temperature range of the thermostat. In the cooling mode, when the thermostat inputs the compressor start signal, if the indoor temperature is lower than the set temperature lower limit of the indoor unit (for example, 17°C), the compressor may stop running when the indoor temperature is not lower than the set temperature lower limit of the thermostat (for example, 10°C), that is, the compressor cannot maintain the running state during the process of the indoor temperature dropping to the set temperature lower limit of the thermostat.

[0037] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0039] The embodiments of the present application provide a control method, device, equipment and storage medium for an air conditioner, aiming to ensure that the compressor can be in operation before receiving a stop signal from a thermostat regardless of how the indoor temperature changes.

[0040] The thermostat outputs 24V switch quantity to the 24V controller to control the air conditioning cooling, heating mode, air supply mode and shutdown mode, thereby controlling the compressor to turn on and off. In the related art, the 24V controller is connected between the indoor and outdoor units. When the 24V controller detects that the thermostat inputs the compressor start signal, when the indoor temperature T1 changes, it adjusts the set temperature Td and sends it to the outdoor unit to ensure that the compressor does not stop.

[0041] In this application, when T1 changes, the method of controlling the compressor to not stop by adjusting the Td logic sent to the air conditioner is not applicable. Because the 24V controller in this application is connected from the indoor unit side, the set temperature range of the indoor unit is usually 17-30°C, and the set temperature range of the thermostat may exceed the range of 17-30°C. According to the relevant technology, when the thermostat inputs the compressor start signal, when the indoor temperature in the cooling mode is lower than 17°C, or when the indoor temperature in the heating mode is higher than 30°C, the compressor will stop, which is not allowed.

[0042] The embodiment of the present application provides a control method for an air conditioner, which is applied to a controller of the air conditioner, and the controller is connected to a thermostat and an indoor unit of the air conditioner respectively; Figure 1 As shown, the method includes:

[0043] Step 101: In response to a start signal from a thermostat, a simulated indoor temperature value is determined based on a set temperature value.

[0044] For example, the start signal of the thermostat can represent a cooling mode signal or a heating mode signal. The controller can be a 24V controller, and correspondingly, the start signal of the thermostat can be a 24V switch quantity sent by the thermostat to the controller, which can represent the switch quantity of the air conditioner cooling or heating mode respectively.

[0045] It is understandable that it is possible to determine whether the actual indoor temperature value satisfies the start-up condition including the set temperature value, and obtain a first judgment result; if the first judgment result indicates that the indoor temperature value does not meet the start-up condition, the simulated indoor temperature value is determined based on the set temperature value. It is understandable that it is also possible to determine whether the simulated indoor temperature value satisfies the shutdown condition including the set temperature value, and obtain a second judgment result; if the second judgment result indicates that the simulated indoor temperature value meets the shutdown condition, the simulated indoor temperature value is updated based on the set temperature value.

[0046] In an application example, determining a simulated indoor temperature value based on a set temperature value includes:

[0047] Determine the critical temperature value of the indoor unit of the air conditioner as the set temperature value;

[0048] Determining a first temperature difference according to a first indoor temperature value and a set temperature value;

[0049] When the first temperature difference does not meet the start-up condition, a simulated indoor temperature value is determined according to the set temperature value and the preset start-up temperature difference value; the simulated indoor temperature value is used to control the compressor of the air conditioner to start.

[0050] Exemplarily, the set temperature value may be any temperature value within the first set temperature range of the indoor unit. In the embodiment of the present application, the critical temperature value of the indoor unit may be the limit value within the first set temperature range of the indoor unit, and the limit value within the first set temperature range of the indoor unit is used as the set temperature value.

[0051] For example, the first set temperature range of the indoor unit is 17-30°C. When the startup signal represents a cooling mode signal, the lower limit value 17°C within the first set temperature range of the indoor unit is used as the set temperature value; when the startup signal represents a heating mode signal, the upper limit value 30°C within the first set temperature range of the indoor unit is used as the set temperature value.

[0052] Exemplarily, the first temperature difference is determined according to the first indoor temperature value and the set temperature value, and the first temperature difference can be obtained by subtracting the first indoor temperature value from the set temperature value.

[0053] For example, the start condition may be that when the start signal represents a cooling mode signal, the first temperature difference is less than the cooling start temperature difference; or when the start signal represents a cooling mode signal, the first indoor temperature value is less than the sum of the critical temperature value and the cooling start temperature difference. The start condition may also be that when the start signal represents a heating mode signal, the first temperature difference is greater than the heating start temperature difference; or when the start signal represents a heating mode signal, the first indoor temperature value is greater than the sum of the critical temperature value and the heating start temperature difference.

[0054] For example, when the start signal represents a cooling mode signal, the preset start temperature difference value may be a cooling start temperature difference; when the start signal represents a heating mode signal, the preset start temperature difference value may be a heating start temperature difference. The simulated indoor temperature value is determined according to the set temperature value and the preset start temperature difference value, and the set temperature value and the preset start temperature difference value are summed to obtain the simulated indoor temperature value.

[0055] In other embodiments, when the air conditioner is not powered on for the first time or the thermostat is not outputting a start signal for the first time, the first temperature value at which the thermostat outputs a stop signal is determined as the set temperature value, wherein the first temperature value is any temperature value within the second set temperature range of the thermostat. Since the first temperature value cannot be obtained by measurement, the second indoor temperature value when the thermostat outputs the stop signal is determined as the first temperature value.

[0056] In an application example, the method further includes:

[0057] When the air conditioner is in air supply mode or shutdown mode, obtaining a second indoor temperature value;

[0058] The second indoor temperature value is determined as the set temperature value.

[0059] For example, after the thermostat outputs a start signal, if the indoor temperature reaches the first temperature value of the thermostat, the thermostat outputs a stop signal, and the second indoor temperature value is determined as the first temperature value, thereby determining the first temperature value as the set temperature value.

[0060] In an application example, the method further includes:

[0061] In the case that the first temperature difference satisfies the start condition, a simulated indoor temperature value is determined based on the first indoor temperature value.

[0062] Exemplarily, determining the simulated indoor temperature value based on the first indoor temperature value may be determining the simulated indoor temperature value based on the first indoor temperature value. Correspondingly, the first indoor temperature value that meets the start-up condition can be used to control the compressor of the air conditioner to start.

[0063] In an application example, determining a simulated indoor temperature value based on a set temperature value further includes:

[0064] Based on a preset time interval, obtain the indoor temperature change value;

[0065] Determine a second temperature difference value according to the simulated indoor temperature value, the indoor temperature change value and the set temperature value;

[0066] When the second temperature difference satisfies the shutdown condition, the simulated indoor temperature value is updated based on the set temperature value; the updated simulated indoor temperature value is used to control the compressor of the air conditioner to be in a running state.

[0067] Exemplarily, the preset time interval can be determined according to actual conditions and is not limited here. As an example, the preset time interval can be 30s.

[0068] Exemplarily, the second temperature difference is determined based on the simulated indoor temperature value, the indoor temperature change value and the set temperature value. The second temperature difference can be determined based on the sum of the simulated indoor temperature value and the indoor temperature change value, and the set temperature value. Specifically, the second temperature difference can be obtained by subtracting the sum of the simulated indoor temperature value and the indoor temperature change value from the set temperature value.

[0069] For example, the shutdown condition may be that when the start signal represents a cooling mode signal, the second temperature difference is less than or equal to the cooling shutdown temperature difference. The startup condition may also be that when the start signal represents a heating mode signal, the second temperature difference is greater than or equal to the heating shutdown temperature difference.

[0070] In an application example, updating a simulated indoor temperature value based on a set temperature value includes:

[0071] The updated simulated indoor temperature value is determined according to the simulated set temperature value, the preset shutdown temperature difference value and the preset frequency reduction temperature difference value.

[0072] For example, when the start signal represents a cooling mode signal, the preset shutdown temperature difference value may be a cooling shutdown temperature difference; when the start signal represents a heating mode signal, the preset shutdown temperature difference value may be a heating shutdown temperature difference. The preset frequency reduction temperature difference value may be a frequency reduction temperature point and a shutdown temperature point.

[0073] Exemplarily, the updated simulated indoor temperature value is determined based on the simulated set temperature value, the preset stop temperature difference value and the preset frequency reduction temperature difference value. When the start signal represents a cooling mode signal, the simulated set temperature value, the preset stop temperature difference value and the preset frequency reduction temperature difference value are summed to obtain the updated simulated indoor temperature value. When the start signal represents a heating mode signal, the updated simulated indoor temperature value is determined based on the sum of the simulated set temperature value and the preset stop temperature difference value, and the preset frequency reduction temperature difference value. Specifically, the sum of the simulated set temperature value and the preset stop temperature difference value can be subtracted from the preset frequency reduction temperature difference value to obtain the updated simulated indoor temperature value.

[0074] In some embodiments, the preset startup temperature difference value, the preset shutdown temperature difference value, and the preset frequency reduction temperature difference value can be set according to the model of the internal unit computing energy requirement or the model of the external unit computing energy requirement.

[0075] In an application example, the method further includes:

[0076] When the second temperature difference value does not satisfy the shutdown condition, an updated simulated indoor temperature value is determined based on the indoor temperature change value.

[0077] Exemplarily, the updated simulated indoor temperature value is determined based on the indoor temperature change value, and the indoor temperature change value and the simulated indoor temperature value are summed to obtain the updated simulated indoor temperature value. Correspondingly, the simulated indoor temperature corresponding to the second temperature difference value that does not meet the shutdown condition can be used to control the compressor of the air conditioner to be in a running state.

[0078] Determining the simulated indoor temperature value based on the first indoor temperature value may be determining the simulated indoor temperature value based on the first indoor temperature value. Correspondingly, the first indoor temperature value that meets the start-up condition can be used to control the compressor of the air conditioner to start.

[0079] Step 102: Send the simulated indoor temperature value to the indoor unit; the simulated indoor temperature value is used to control the compressor of the air conditioner to start and / or be in a running state.

[0080] Exemplarily, when the indoor temperature value does not meet the start-up conditions, the simulated indoor temperature is sent to the indoor unit instead of the indoor temperature value; at this time, the indoor unit determines that the indoor temperature of the mode meets the start-up conditions and outputs a compressor start signal to the compressor.

[0081] In some embodiments, when the indoor temperature value meets the start-up conditions, the indoor temperature value is sent to the indoor unit as a simulated indoor temperature; at this time, the indoor unit determines that the indoor temperature value as the simulated indoor temperature meets the start-up conditions, and outputs a compressor start signal to the compressor.

[0082] Exemplarily, after the compressor is turned on, when the simulated indoor temperature meets the shutdown conditions, the updated simulated indoor temperature value determined according to the simulated set temperature value, the preset shutdown temperature difference value and the preset frequency reduction temperature difference value is sent to the indoor unit, and the indoor unit can increase or decrease the frequency according to energy demand to ensure that the compressor does not stop.

[0083] In some embodiments, after the compressor is turned on, if the simulated indoor temperature does not meet the shutdown conditions, the updated simulated indoor temperature value determined based on the simulated indoor temperature and the indoor temperature change value is sent to the indoor unit, and the indoor unit can still increase or decrease the frequency according to energy demand to ensure that the compressor does not stop.

[0084] Step 103: In response to a stop signal from the thermostat, control the compressor to turn off.

[0085] For example, the stop signal of the thermostat may also be a 24V switch quantity sent by the thermostat to the controller, which may respectively represent the switch quantity of the air supply mode or the shutdown mode. Correspondingly, controlling the compressor to shut down may be controlling the air conditioner to be in the air supply mode or the shutdown mode.

[0086] The embodiment of the present application uses a 24V controller to fix the set temperature TS, and also adjusts the simulated indoor temperature T1S of the indoor unit to ensure that the compressor does not stop when the thermostat outputs a signal to start the compressor. This solves the problem of the compressor stopping when the thermostat set temperature exceeds the indoor unit set temperature range of 17 to 30°C and the indoor temperature exceeds the indoor unit set temperature range of 17 to 30°C in the application scenario where the 24V controller of the present application is connected from the indoor unit side.

[0087] That is to say, when the thermostat outputs the compressor start signal, no matter how the indoor temperature changes, the calculation rules of the indoor unit T1S and TS in this technology can ensure that the compressor is in the energy demand range. At the same time, this technology can also realize the air conditioning frequency conversion function under 24V control.

[0088] In addition, the embodiment of the present application provides a universal method that is compatible with various existing types of systems (air-conditioning systems that calculate energy requirements for external units and air-conditioning systems that calculate energy requirements for internal units).

[0089] In order to understand the embodiments of the present invention, a control method based on a 24V controller in an air conditioner is taken as an example for description below.

[0090] Before explaining the control method of the air conditioner in the embodiment of the present application, an exemplary explanation of the key terminology of the air conditioner is first given.

[0091] T1: 24V controller collects the actual indoor temperature value (unit: Celsius);

[0092] TS: The set temperature value sent by the 24V controller to the indoor unit of the air conditioner (unit: Celsius);

[0093] T1S: The simulated indoor temperature value (unit: Celsius) sent by the 24V controller to the air conditioner indoor unit;

[0094] CSTART_TDIFF: Refrigeration start temperature difference (unit: Celsius);

[0095] HSTART_TDIFF: Heating start temperature difference (unit: Celsius);

[0096] CSTOP_TDIFF: Refrigeration shutdown temperature difference (unit: Celsius);

[0097] HSTOP_TDIFF: Heating shutdown temperature difference (unit: Celsius);

[0098] REDUCE_TDIFF: Temperature difference between the frequency reduction temperature point and the shutdown temperature point (unit: degree Celsius).

[0099] As Figure 2 shown, the control method based on the 24V controller in the air conditioner includes the following steps:

[0100] Step 201: Power on the 24V controller.

[0101] Step 202: Set the refrigeration start temperature difference CSTART_TDIFF, the heating start temperature difference HSTART_TDIFF, the refrigeration shutdown temperature difference CSTOP_TDIFF, the heating shutdown temperature difference HSTOP_TDIFF, and the temperature difference REDUCE_TDIFF between the frequency reduction temperature point and the shutdown temperature point according to the model that calculates the energy demand of the indoor unit or the model that calculates the energy demand of the outdoor unit.

[0102] Step 203: Determine whether the thermostat outputs the refrigeration mode. If so, execute Step 206; if not, execute Step 204.

[0103] Step 204: Determine whether it is the air supply or shutdown mode. If so, execute Step 205; if not, execute Step 218.

[0104] Exemplarily, determine whether the thermostat outputs the air supply mode switch signal or the shutdown mode switch signal.

[0105] Step 205: Record the current indoor temperature T1 as the thermostat set temperature TherTS.

[0106] Step 206: Determine whether it is the non-first power-on or output. If not, execute Step 207; if so, execute Step 208.

[0107] Exemplarily, determine whether it is the non-first power-on of the air conditioner or the thermostat outputs the refrigeration mode switch signal. If not, it is the first power-on of the air conditioner or the thermostat outputs the refrigeration mode switch signal, and execute Step 207; if so, it is the non-first power-on of the air conditioner or the thermostat outputs the refrigeration mode switch signal, and execute Step 208.

[0108] Step 207: Update the set temperature TS to the lower limit of the indoor unit set temperature.

[0109] Exemplarily, the set temperature TS of the indoor unit in the refrigeration mode is the lower limit within the set temperature range of the indoor unit.

[0110] Step 208: Update the set temperature TS to TherTS.

[0111] Step 209: Determine whether T1 < TS + CSTART_TDIFF. If so, execute Step 210; if not, execute Step 211.

[0112] Step 210: The indoor unit simulates the indoor temperature T1S=TS+CSTART_TDIFF.

[0113] Step 211: Simulate the indoor temperature T1S=T1.

[0114] Step 212: Determine whether the 30S timer has timed out. If so, execute step 213; if not, execute step 212.

[0115] Step 213: Calculate the indoor temperature change value ΔT.

[0116] Step 214: Determine whether (T1S+ΔT)-TS≤CSTOP_TDIFF, if so, execute step 215; if not, execute step 216.

[0117] Step 215: T1S=TS+CSTOP_TDIFF+REDUCE_TDIFF.

[0118] Exemplarily, when the simulated indoor temperature T1S drops to the shutdown temperature point, the simulated indoor temperature value is adjusted to reduce the frequency of the outdoor unit, but the compressor is not stopped.

[0119] Step 216: T1S=T1S+ΔT.

[0120] Step 217: Send the simulated indoor temperature T1S and the set temperature TS to the indoor unit.

[0121] For example, the indoor unit will calculate the frequency increase or decrease according to the energy demand to achieve the purpose of frequency conversion.

[0122] Step 218: Determine whether the thermostat outputs the heating mode, if so, execute step 219; if not, execute step 203.

[0123] Step 219: Determine whether it is not the first power-on or output. If not, execute step 220; if yes, execute step 221.

[0124] Exemplarily, determine whether it is not the first time that the air conditioner is powered on or the thermostat outputs a heating mode switch signal. If not, it is the first time that the air conditioner is powered on or the thermostat outputs a heating mode switch signal, and execute step 220; if yes, it is not the first time that the air conditioner is powered on or the thermostat outputs a heating mode switch signal, and execute step 221.

[0125] Step 220: Update the set temperature TS to the upper limit of the indoor unit temperature.

[0126] Exemplarily, the set temperature TS of the indoor unit in the heating mode is the upper limit of the set temperature range of the indoor unit.

[0127] Step 221: Update the set temperature TS to TherTS.

[0128] Step 222: Determine whether T1-TS>HSTART_TDIFF, if so, execute step 223; if not, execute step 224.

[0129] Step 223: The indoor unit simulates the indoor temperature T1S=TS+HSTART_TDIFF.

[0130] Step 224: Simulate the indoor temperature T1S=T1.

[0131] Step 225: Determine whether the 30S timer has timed out. If so, execute step 226; if not, execute step 225.

[0132] Step 226: Calculate the indoor temperature change value ΔT.

[0133] Step 227: Determine whether (T1S+ΔT)-TS≥HSTOP_TDIFF, if so, execute step 228; if not, execute step 229.

[0134] Step 228: T1S=TS+HSTOP_TDIFF-REDUCE_TDIFF.

[0135] Exemplarily, when the simulated indoor temperature T1S drops to the shutdown temperature point, the simulated indoor temperature value is adjusted to reduce the frequency of the outdoor unit, but the compressor is not stopped.

[0136] Step 229: T1S=T1S+ΔT.

[0137] Step 230: Send the simulated indoor temperature T1S and the set temperature TS to the indoor unit.

[0138] For example, the indoor unit will calculate the frequency increase or decrease according to the energy demand to achieve the purpose of frequency conversion.
