Examples

Fig. 1 is an explanatory diagram showing an example of an air conditioning system 1 of the present embodiment. The air conditioning system shown in fig. 1 includes: an air conditioner 10, an air blower 30, and a learning control device 20.

The air conditioner 10 is a device that appropriately satisfies the indoor cooling/heating load requirement by controlling the refrigerant circulation amount of the compressor and the refrigerant flow rate into the indoor heat exchanger in the refrigeration system. Specifically, the air conditioner 10 employs a compression refrigeration cycle, and includes a refrigerant circuit including four main components, i.e., a compressor, a condenser (high-temperature heat source), a throttle element, and an evaporator (low-temperature heat source), in which a refrigerant circulates through the compressor, the condenser, the throttle element, and the evaporator in this order.

In the present embodiment, the cooling and heating cycle of the air conditioner 10 includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat the indoor space.

The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

The throttle element, taking the expansion valve as an example, expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigerating effect by heat exchange with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioning unit 10 may regulate the temperature of the air conditioned room indoor space throughout the cycle.

The outdoor unit of the air conditioner 10 refers to a portion of a refrigeration cycle including a compressor, an outdoor heat exchanger, and an outdoor fan, the indoor unit of the air conditioner 10 refers to a portion including an indoor heat exchanger and an indoor fan, and a throttling device (such as a capillary tube or an electronic expansion valve) may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. The air conditioning device 10 performs a heating mode when the indoor heat exchanger functions as a condenser, and the air conditioning device 10 performs a cooling mode when the indoor heat exchanger functions as an evaporator.

The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, and a four-way valve is generally adopted, which is specifically referred to the setting of the conventional air conditioning device 10 and is not described herein again.

The cooling operation principle of the air conditioner 10 is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is quickly evaporated to absorb heat, air blown out by the indoor fan flows through the coil pipe of the indoor heat exchanger to be cooled and becomes cold air to be blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor and then is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, the heat is dissipated into the atmosphere through the outdoor fan, and the refrigeration effect is achieved through the circulation.

The heating operation principle of the air conditioner 10 is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at this time), is evaporated, gasified and absorbs heat to form gas, absorbs heat of outdoor air (the outdoor air becomes cooler), becomes a gaseous refrigerant, and enters the compressor again to start the next cycle.

The air conditioner 10 uses an inverter compressor to control the capacity of the compressor, and supplies ac power to the compressor through the inverter. When the output frequency of the frequency conversion device changes, the rotating speed of the compressor changes, and the air conditioning capacity matched with different heat loads is realized.

In some alternative embodiments of the present application, the indoor unit may employ an independent air supply mechanism. For example, a wall-mounted air supply structure is adopted, namely, the wall-mounted air supply structure is provided with an air return opening arranged above the shell and an air supply opening arranged below the shell; the floor type air supply structure is provided with an air supply outlet arranged above the shell and air return outlets arranged at the left side and the right side below the shell, and can also be an air pipe type air supply structure, an air supply structure embedded in a ceiling, and the like.

Wherein the storage unit may comprise volatile memory and/or non-volatile memory. The storage unit is configured to store instructions or data, such as an application program, associated with at least one component of the outdoor unit. The input/output interface may be a serial communication interface. The communication interface may be a software interface supporting different wireless communication protocols. The outdoor unit main board is usually integrated with a filter circuit and a switching power supply circuit.

The air conditioner control part 100 may execute an application program stored in the storage unit to compare the collected parameters related to the indoor ambient temperature in the air-conditioned room with the set temperature stored in the storage unit at any time, and output a control signal after an arithmetic process, so that the inverter compressor continuously changes in a set frequency range (e.g., 12-150 Hz); or the opening of the electronic expansion valve is controlled according to the information collected by temperature sensors arranged at the inlet and the outlet of the electronic expansion valve, the air suction port of the compressor and the like, so that the flow of the refrigerant can be changed at any time. The rotation speed of the compressor corresponds to the opening degree of the electronic expansion valve, so that the delivery capacity of the compressor is adapted to the supply capacity of the electronic expansion valve, the superheat degree of the compressor is not too large, the capacity of the evaporator is exerted to the maximum extent, and the air conditioner 10 is optimally controlled.

In some optional real-time modes of the present application, the indoor ambient temperature and the set temperature among the above parameters are obtained by the processing chip. The processing chip is arranged on the indoor unit main board, and the indoor unit main board and the outdoor unit main board are in communication connection through the serial communication interface.

The air blower 30 may be an electric fan, an air cleaner, a household dehumidifier, or an indoor fan of an indoor unit of another air conditioner 10. The air supply device 30 is independent of the air conditioner 10, i.e., its power supply, operation, and air supply trajectory are independent of the air conditioner 10.

The blower 30 includes an infrared receiver 300 that receives an infrared operation. The infrared receiver 300 is used for receiving an operation command of the air supply device infrared remote controller 301 to control the operation of the air supply device 30, that is, the infrared receiver 300 can amplify, detect, shape, demodulate a remote control signal of the air supply device infrared remote controller 301 to obtain a remote control coded pulse, and further control the operation of the air supply device 30. The air supply device 30 is provided with a microprocessor for decoding the operation instruction and executing a remote control function of response.

The learning control device 20 includes an infrared transmitter 200. The learning control device 20 is configured to learn and store an operation instruction of the air blowing device 30 by the air blowing device infrared remote controller 301 when the air conditioning apparatus 10 is in an operating state. The learning control device 20 is further configured to, after storing at least one operation command of the air blowing device 30 by the air blowing device infrared remote controller 301, select among the stored operation commands according to the actual heat load of the air-conditioned room, and output the selected matching operation command to the infrared receiving section 300 through the infrared transmitting section 200 to control the operation of the air blowing device 30.

In some optional embodiments of the present application, the infrared transmitter 200 of the learning control device 20 may be disposed on the indoor unit casing of the air conditioner. Other functions of the learning control apparatus 20 are realized by the processing chip.

Fig. 2 is a flowchart showing the function of the learning control apparatus 20. In the present embodiment, the air blowing device 30 is an electric fan. The learning control device 20 determines whether the air conditioner 10 is in an operating state (as shown in step S11 in fig. 2); when the air conditioner 10 is in an operating state, an operation instruction of the air supply device infrared remote controller 301 to the air supply device 30 is learned and stored (as shown in step S12 in fig. 2): if there is an operation instruction output from the infrared remote controller 301 of the air supply device to the air supply device 30 while the air conditioner 10 is in the operating state, the learning control device 20 learns and stores the operation instruction, and if there is no operation instruction output from the infrared remote controller 301 of the air supply device to the air supply device 30, the learning control device 20 maintains the waiting state; the learning control device 20 determines whether at least one operation command of the air blowing device infrared remote controller 301 to the air blowing device 30 is stored (as shown in step S13 in fig. 2); when at least one operation command of air blower infrared remote control 301 for air blower 30 is stored, learning control device 20 selects from the stored operation commands according to the actual heat load of the air-conditioned room (as shown in step S14 in fig. 2): illustratively, if the learning control device 20 stores an operation instruction of the air supply device infrared remote controller 301 to the air supply device 30, the operation instruction comprises: starting up (function instruction code 01), high wind (function instruction code 02), medium wind (function instruction code 03), low wind (function instruction code 04), swing air supply (function instruction code 05), swing air supply stopping (function instruction code 06) and shutdown (function instruction code 00); if the operation instruction input by the air-conditioning control terminal 101 corresponds to a refrigeration mode, a set temperature is 19 ℃, a high-speed air supply mode is performed, and the temperature difference between the real-time temperature and the set temperature of the air-conditioning room deviates from a target interval, the learning control device 20 selects from the stored operation instruction according to the degree that the real-time heat load of the air-conditioning room deviates from the set target, and the selection principle can be that the higher the real-time heat load is, the larger the air supply air volume is; the smaller the real-time thermal load, the smaller the blowing air volume. Illustratively, power-on (function instruction code 01) and high wind (function instruction code 02) are selected. The learning control device 20 outputs the selected matching operation command to the infrared receiving unit 300 through the infrared transmitter unit 200 to control the operation of the air blowing device 30 (as shown in step S15 in fig. 2), that is, the air blowing device 30 keeps on operating and high wind. If the temperature difference between the real-time temperature and the set temperature is maintained in the target range, the learning control device 20 exemplarily selects shutdown (function instruction code 00) as the matching operation instruction, and outputs the same to the infrared ray receiving part 300 through the infrared ray transmitting part 200 to control the operation of the air supply device 30.

The learning control device 20 can learn an operation command of any one of the air blowing devices 30 having the infrared receiver 300. With this configuration, the air conditioner 10 can be adapted to any one of the air blowing devices 30 having the infrared receiver 300 and the infrared remote controller 301, and the adaptation process does not depend on a local area network or a mobile intelligent terminal; the issuing of the matching operation instruction is not limited by the network environment, the control effect does not generate time difference, the air supply device 30 responds quickly, the linkage of the air conditioner device 10 and the air supply device 30 is realized, and the energy-saving control effect is achieved. The learning control device 20 is configured to learn and store an operation instruction of the air supply device 30 by the air supply device infrared remote controller 301 when the air conditioner 10 is in an operating state, and the operation instruction matches with the user's desire, for example, when the air conditioner 10 is in an operating state, the learning control device 20 does not learn and store a high wind instruction all the time, which indicates that the user does not need to set the electric fan to be high wind (the high wind may cause discomfort) while turning on the air conditioner 10 and the electric fan, and the learning control device 20 does not set the electric fan to be high wind and always selects between medium wind and low wind no matter how the actual heat load of the air-conditioned room changes, thereby ensuring that the effect of the intelligent control matches with the user. In the whole learning and setting process, the user still uses the traditional infrared remote controller to operate the air supply device 30 without operating on the application of the smart phone, so that the intelligent mobile phone is more suitable for the elders and people who are not familiar with the smart device, and the user experience is good.

In some alternative embodiments of the present application, as shown in fig. 3, the air blowing device 30 has an air blowing device storage section 302. Air supply device storage 302 may be a volatile memory and/or a non-volatile memory integrated into air supply device 30. The air blowing device storage unit 302 stores an operation instruction of the air blowing device 30 by the air blowing device infrared remote controller 301. The learning control device 20 learns the operation command of the user from the blower storage unit 302. Specifically, at the time of first use or initial use, the learning control device 20 may execute a plurality of steps as shown in fig. 4: determining whether the air conditioner 10 is in a standby state (as shown in step S21 in fig. 4); when the air conditioner 10 is in the standby state, the learning control device 20 attempts to establish a communication connection with the air blowing device 30 (as shown in step S22 in fig. 4), for example, attempts to establish an infrared communication connection; determining whether the communication connection is successful (as shown in step S23 in fig. 4); when the communication connection is successful, an initial operation command for the air blowing device 30 by the air blowing device infrared remote control 301 is read from the air blowing device storage unit 302 (as shown in step S24 in fig. 4); the learning control means 20 learns and stores the read initial operation instruction (as shown in step S25 in fig. 4), which may be regarded as the operation habit of the user on the air blowing means 30, such as an electric fan, and the user may use only high wind or medium wind, or only low wind, or only swing air blowing, and the learning control means 20 learns and stores the read initial operation instruction; power-down protection is performed on the learned and stored initial operation instruction (as shown in step S26 in fig. 4), and the stored state of the initial operation instruction is maintained even if the power of the learning control apparatus 20 is turned off. When the air blower 30 is initially used in conjunction with the air conditioner 10, the learning control device 20 may select from the stored initial operation commands, and output the selected matching operation command to the infrared receiver 300 through the infrared transmitter 200 to control the operation of the air blower 30; for example, if the user does not use the high wind or stroke command at ordinary times, the learning control device 20 will automatically filter out the high wind or stroke command during the linkage control, and only select from the stored operation commands, so that the linkage control is more suitable for the use habit of the user.

In some optional embodiments of the present application, as shown in fig. 5, the air supply device 30 and the air conditioner 10 may be paired during the use of the air conditioner 10; for example, the user may recognize that the conditioning effect is not ideal during the use of the air conditioner 10, and add an electric fan to the air-conditioned room, in which case, as shown in fig. 5, the learning control device 20 performs a plurality of steps as shown in fig. 5: determining whether the air conditioner 10 is in an operating state (as shown in step S31 in fig. 5); when the air conditioner 10 is in an operating state, the learning control device 20 attempts to establish a communication connection with the air supply device 30 (as shown in step S32 in fig. 5), for example, attempts to establish an infrared communication connection; determining whether the communication connection is successful (as shown in step S33 in fig. 5); when the communication connection is successful, an auxiliary operation command of the air supply device infrared remote controller 301 to the air supply device 30 is read from the air supply device storage unit 302 (as shown in step S34 in fig. 5), and the auxiliary operation command can be regarded as an active intervention operation of the user when the adjustment effect on the air conditioner 10 is not satisfactory; the learning control means 20 learns and stores the assist operation instruction (as shown in step S35 in fig. 5); performing power-down protection on the learned and stored auxiliary operation command (as shown in step S36 in fig. 5), keeping the stored state of the initial operation command unchanged even if the power of the learning control device 20 is turned off; when one air supply device 30 is additionally arranged, a user can certainly perform at least the operations of starting and stopping the air supply device, so that the learning control device 20 can realize the pairing and learning process with the newly added air supply device 30 in the operation process of the air conditioner 10.

In some alternative embodiments of the present application, as shown in fig. 6, the learning control device 20 may also continuously update the learned and stored operation commands during the use of the air conditioner 10.

The air blowing device 30 has different functions, for example, a part of the electric fan has a swing air blowing function, and a part of the electric fan does not have a swing air blowing function. To achieve the discrimination, the learning control device 20 is further configured to acquire the available functions of the air supply device 30 by polling after establishing a communication connection with the air supply device 30.

Fig. 9 and 10 are schematic diagrams showing the effect of the control of the wind speed intervention operation command, increasing the air volume F1 (indicated by a thin legend F1 in state S1) to the air volume F2 (indicated by a thick legend F2 in state S2).

The electric fan, the air purification equipment, the dehumidifier and other equipment with the air supply function have the characteristic of mobility. If the position is changed, the auxiliary adjusting function of the air-conditioning room is changed, and the effect of the linkage control with the air-conditioning device 10 is also changed. If the learning control device 20 is also designed to perform control using the same matching operation instruction after the position of the air blowing device 30 is changed, the effect of the assist adjustment may deviate from the control target.
