It should be noted that, in other embodiments, the preset state may be defined as off, and the non-preset state may be defined as on.
And S120, if the setting mode is a preset setting mode, controlling the air conditioner according to the setting temperature, and adjusting the setting temperature according to the running signal and the received indoor environment temperature sent by the air conditioner to obtain a target setting temperature.
In the embodiment of the invention, whether the setting mode of the air conditioner is the preset setting mode is judged according to the load switch signal, if the setting mode is the preset setting mode, the 24V converter sends the setting temperature corresponding to the preset setting mode to the air conditioner, the air conditioner operates at the setting temperature, at the moment, the indoor environment temperature continuously changes, the air conditioner collects the indoor environment temperature in real time and sends the collected indoor environment temperature to the 24V converter, and the 24V converter adjusts the setting temperature according to the received operation signal and the indoor environment temperature to obtain the target setting temperature. It should be noted that, in the embodiment of the present invention, the preset setting mode includes a cooling mode and a heating mode; if the air conditioner is operated for the first time, the set temperature is a factory initial default set temperature of the 24V converter, for example, the set temperature in the refrigeration mode may be set to 16 ℃ to ensure that the air conditioner is cooled to a certain extent, the set temperature in the heating mode may be set to 30 ℃ to ensure that the air conditioner is heated to a certain extent, and the set temperature may be reasonably set according to actual requirements, which is not limited in detail herein; and if the air conditioner is not operated for the first time, the set temperature is updated when the air conditioner is stopped last time. In the embodiment of the present invention, the indoor environment temperature is acquired by an environment temperature sensing bulb installed in the indoor unit of the air conditioner, a communication protocol exists between the air conditioner and the 24V converter, and the indoor environment temperature is sent to the 24V converter by the air conditioner through the communication protocol.
Further, as shown in fig. 3, step S120 may specifically include steps S121 to S122: s121, if the set mode is the refrigeration mode, controlling the air conditioner according to the refrigeration set temperature, and adjusting the refrigeration set temperature according to the operation signal and the received indoor environment temperature sent by the air conditioner to obtain a target refrigeration set temperature; and S122, if the setting mode is the heating mode, controlling the air conditioner according to the heating set temperature, and adjusting the heating set temperature according to the operation signal and the indoor environment temperature to obtain a target heating set temperature. Specifically, the set temperature includes a refrigeration set temperature and a heating set temperature; if the set mode is the refrigeration mode, the 24V converter sends the refrigeration set temperature to the air conditioner to enable the air conditioner to operate at the refrigeration set temperature, at the moment, the indoor environment temperature is reduced, and the 24V converter adjusts the refrigeration set temperature according to the operation signal and the indoor environment temperature to obtain a target refrigeration set temperature; and if the setting mode is the heating mode, the 24V converter sends the heating set temperature to the air conditioner to enable the air conditioner to operate at the heating set temperature, at the moment, the indoor environment temperature rises, and the 24V converter adjusts the heating set temperature according to the operation signal and the indoor environment temperature to obtain a target heating set temperature.
Further, as shown in fig. 3, step S121 may specifically include steps S1211-S1212: s1211, if the operation signal is a non-preset state signal, updating the refrigeration set temperature according to a compensation temperature value and the indoor environment temperature to obtain the target refrigeration set temperature, and controlling a compressor in the air conditioner to stop operation; s1212, if the operation signal is a preset state signal, the step of updating the refrigeration set temperature according to the compensation temperature value and the indoor environment temperature to obtain the target refrigeration set temperature is executed. Specifically, in the cooling mode, judging the state of the operation signal, if the operation signal is a non-preset state signal, that is, the 24V converter does not receive the operation signal sent by the temperature controller, which indicates that a user has no cooling requirement at the moment, defaulting the air conditioner to meet the stop requirement, updating the cooling set temperature according to the compensation temperature value and the indoor environment temperature to obtain the target cooling set temperature, and controlling a compressor in the air conditioner to stop running; if the operation signal is a preset state signal, that is, the 24V converter continuously receives the operation signal sent by the temperature controller, whether the shutdown requirement is met or not is further judged according to the compensation temperature value and the indoor environment temperature, and the refrigeration set temperature is updated to obtain the target refrigeration set temperature. It should be noted that, in other embodiments, the compensation temperature value may be set reasonably according to actual requirements, which is not limited herein.
As shown in fig. 3, step S122 may specifically include steps S1221 to S1222: s1221, if the operation signal is a non-preset state signal, updating the heating set temperature according to a compensation temperature value and the indoor environment temperature to obtain the target heating set temperature, and controlling a compressor in the air conditioner to stop operation; s1222, if the operation signal is a preset state signal, executing the step of updating the heating set temperature according to the compensation temperature value and the indoor environment temperature to obtain the target heating set temperature. Specifically, in the heating mode, judging the state of the operation signal, if the operation signal is a non-preset state signal, that is, the 24V converter does not receive the operation signal sent by the temperature controller, which indicates that a user has no heating requirement at the moment, defaulting the air conditioner to meet a shutdown requirement, updating the heating set temperature according to the compensation temperature value and the indoor environment temperature to obtain the target heating set temperature, and controlling a compressor in the air conditioner to stop running; if the operation signal is a preset state signal, that is, the 24V converter continuously receives the operation signal sent by the temperature controller, whether the shutdown requirement is met or not is further judged according to the compensation temperature value and the indoor environment temperature, and the heating set temperature is updated to obtain the target heating set temperature.
Still further, step S1211 specifically includes: calculating the difference between the refrigeration set temperature and the compensation temperature value to obtain a refrigeration temperature difference; and if the refrigerating temperature difference is greater than or equal to the indoor environment temperature, updating the refrigerating set temperature according to the indoor environment temperature and the compensation temperature value to obtain the target refrigerating set temperature. For ease of understanding and description, the refrigeration set temperature, the compensation temperature value, and the indoor environment temperature are respectively denoted as Tref1, Δt, and T. Specifically, in a refrigeration mode, firstly calculating the refrigeration temperature difference, namely calculating Tref 1-delta T; if the air conditioner runs for the first time, judging whether the refrigerating temperature difference is larger than or equal to the indoor environment temperature, namely judging whether the refrigerating temperature difference is smaller than or equal to the indoor environment temperature, namely, meeting the refrigerating requirement, and updating the refrigerating set temperature to obtain the target refrigerating set temperature, namely, taking T+delta T as the target refrigerating set temperature; if the air conditioner is not operated for the first time, the 24V converter continuously receives the operation signal and meets T less than or equal to Tref 1-delta T, the temperature controller is indicated not to require the air conditioner to stop, it is determined that Tref1 is not consistent with the actual set temperature of a user, tref1 is higher than the actual set temperature of the user, tref1-1 is used as the target refrigeration set temperature, for example, if Tref1 is assumed to be 22 ℃, delta T is 2 ℃ and T is 20 ℃, namely 20 is less than or equal to 22-2, T is indicated to be met, T is less than or equal to Tref 1-delta T, if the operation signal is still received at the moment, namely the temperature controller is not required to stop the air conditioner, tref1 is updated to obtain the target refrigeration set temperature to be 21 ℃ until the operation signal is not received and T is less than or equal to Tref 1-delta T, the target refrigeration set temperature at the moment is recorded, and the target refrigeration set temperature at the moment is used as the set temperature for the next starting-up operation of the air conditioner. It should be noted that, in the embodiment of the present invention, the shutdown refers to stopping the operation of the compressor, while the fan still maintains the operation.
The step S1221 specifically includes: calculating the sum of the heating set temperature and the compensation temperature value to obtain a heating temperature sum; and if the heating temperature and the indoor environment temperature are smaller than or equal to each other, updating the heating set temperature according to the indoor environment temperature and the compensation temperature value to obtain the target heating set temperature. For ease of understanding and description, the heating set temperature, the compensation temperature value, and the indoor environment temperature are denoted as Tref2, Δt, and T. Specifically, under a heating mode, firstly calculating a heating temperature sum, namely calculating tref2+delta T; if the air conditioner runs for the first time, judging whether the heating temperature sum is smaller than or equal to the indoor environment temperature, namely judging whether the shutdown requirement T is larger than or equal to tref2+delta T, if the heating temperature sum is smaller than or equal to the indoor environment temperature, namely meeting the shutdown requirement, updating the heating set temperature to obtain the target heating set temperature, namely taking T-delta T as the target heating set temperature; if the air conditioner is not operated for the first time, the 24V converter continuously receives the operation signal and meets T more than or equal to tref2+delta T, the temperature controller does not require the air conditioner to stop, it is judged that Tref2 is not consistent with the actual set temperature of a user, tref2 is lower than the actual set temperature of the user, the set temperature of heating is updated to obtain the set temperature of target heating, namely tref2+1 is used as the set temperature of target heating until the temperature controller is met at the same time, the operation signal is not sent by the temperature controller, T more than or equal to tref2+delta T is recorded, the set temperature of target heating at the moment is recorded, and the set temperature of target heating at the moment is used as the set temperature of the next starting operation of the air conditioner.
And S130, controlling the air conditioner according to the target set temperature.
In the embodiment of the invention, after the set temperature is updated according to the operation signal, the indoor environment temperature and the compensation temperature value to obtain the target set temperature, the target set temperature is sent to the air conditioner, and the air conditioner is controlled to operate at the target set temperature.
Referring to fig. 4, fig. 4 is a flow chart of a control method of an air conditioner according to an embodiment of the present invention, in fig. 4, if the air conditioner is operated for the first time, after the air conditioner is started, a 24V converter receives a load switch signal sent by a temperature controller; judging the operation mode of the air conditioner; if the air conditioner is in a refrigerating mode, the 24V converter sends a refrigerating set temperature Tref1 to the air conditioner; the air conditioner operates according to a refrigerating mode of Tref1, and the indoor environment temperature T is reduced; the 24V converter receives the T collected by the air conditioner in real time; judging whether the temperature controller still sends an operation signal; if no running signal is sent, the default air conditioner meets the stop requirement, which indicates that the user has no refrigeration requirement, and the Tref1 is updated by T+delta T, and the stop of the compressor is controlled; if the running signal is still sent, further judging whether the shutdown requirement T is less than or equal to Tref 1-delta T or not; if the shutdown requirement is not met, the air conditioner operates according to a refrigerating mode of Tref1, and the indoor environment temperature T is reduced; if the shutdown requirement is met, the set temperature Tref1 of the 24V converter is indicated to be wrong, tref1 is updated by T+delta T, and the updated Tref1 is sent to the air conditioner. If the heating mode is adopted, the 24V converter sends a heating set temperature Tref2 to the air conditioner; the air conditioner operates according to a heating mode of Tref2, and the indoor environment temperature T rises; the 24V converter receives the T collected by the air conditioner in real time; judging whether the temperature controller still sends an operation signal; if no running signal is sent, the default air conditioner meets the stop requirement, which indicates that a user has no heating requirement, and the Tref2 is updated by T-delta T, and the stop of the compressor is controlled; if the running signal is still sent, further judging whether the shutdown requirement T is more than or equal to tref2+delta T or not; if the shutdown requirement is not met, the air conditioner operates according to a heating mode of Tref2, and the indoor environment temperature T rises; if the shutdown requirement is met, the heating set temperature Tref2 of the 24V converter is indicated to be wrong, tref2 is updated by T-delta T, and the updated Tref2 is sent to the air conditioner.
As can be seen from the foregoing, in this embodiment, according to the load switch signal sent by the temperature controller, the indoor environment temperature collected by the air conditioner, and the shutdown condition of the air conditioner, the set temperature inside the 24V converter is adjusted to estimate the actual set temperature of the user, so as to control the air conditioner to operate at a suitable temperature, reduce the power consumption of the air conditioner, and improve the user comfort.
