[0034] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0035] The air conditioner in the present invention performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0036] The compressor compresses the refrigerant gas in a high temperature and high pressure state and discharges the compressed refrigerant gas. 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.

[0037] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-temperature and low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0038] Reference below Figure 1-Figure 6The air conditioner 1 and the control method thereof according to the embodiment of the present invention are described.

[0039] like Figure 1 As shown, the air conditioner 1 according to the embodiment of the present invention includes: a casing 10 , a refrigerant circulation loop 20 , a refrigeration system 30 , an infrared image acquisition device 40 , an indoor temperature sensor 50 , an outdoor temperature sensor 60 and a controller 70 .

[0040] The refrigerant circulation loop 20 allows the refrigerant to circulate in a loop composed of a compressor, a condenser, an expansion valve, an evaporator, a four-way valve, and a pressure reducer; the refrigeration system 30 is arranged in the housing 10, and the housing 10 can provide protection for it. The refrigeration system 30 performs heat exchange between the refrigerant and the indoor air in the compression refrigeration cycle of the refrigerant circulation loop 20; the refrigeration system 30 includes a compressor, which is used to compress the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure refrigerant gas and discharge it to the condenser.

[0041] The infrared image acquisition device 40 is disposed in the housing 10 and is used to scan the indoor environment and generate a panoramic infrared image of the indoor environment; the indoor temperature sensor 50 is used to detect the temperature of the indoor environment; and the outdoor temperature sensor 60 is used to detect the temperature of the outdoor environment.

[0042] The controller 70 is configured to: obtain the temperature of the indoor environment, the temperature of the outdoor environment and the panoramic infrared image; determine the output capacity value of the compressor according to the temperature of the indoor environment and the temperature of the outdoor environment; determine the heat dissipation of the indoor heat source in the indoor environment according to the temperature of the indoor environment and the panoramic infrared image; and correct the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor to reduce the temperature fluctuation of the indoor environment.

[0043] Specifically, when the air conditioner 1 is started, the controller 70 obtains the panoramic infrared image, the temperature of the indoor environment and the temperature of the outdoor environment corresponding to the infrared image acquisition device 40, the indoor temperature sensor 50 and the outdoor temperature sensor 60, and determines the output capacity value of the compressor and the heat dissipation of the indoor heat source in the indoor environment. The target operating frequency of the compressor is adaptively adjusted according to the heat dissipation of the indoor heat source and the output capacity value of the compressor, so as to reduce the temperature fluctuation of the indoor environment to ensure the comfort of the user and the energy saving effect of the compressor. Specifically, when the air conditioner 1 is started, the infrared image acquisition device 40 can use the infrared wavelength released by heat to scan the indoor environment and convert the thermal radiation into an image signal, thereby showing the temperature change and distribution of the indoor heat source, and generating a panoramic infrared image of the indoor environment. At the same time, the indoor temperature sensor 50 and the outdoor temperature sensor 60 detect the temperature of the indoor environment and the temperature change of the outdoor environment in real time. Furthermore, the controller 70 determines the output capacity value of the compressor based on the temperature of the indoor environment and the temperature of the outdoor environment, and determines the heat dissipation of the indoor heat source in the indoor environment based on the temperature of the indoor environment and the panoramic infrared image, so as to correct the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor to reduce the temperature fluctuation of the indoor environment, thereby ensuring the comfort of the user and the energy-saving effect of the compressor.

[0044] According to the air conditioner 1 of the embodiment of the present invention, by setting an infrared image acquisition device 40, an indoor temperature sensor 50 and an outdoor temperature sensor 60, the panoramic infrared image of the indoor environment, the temperature of the indoor environment and the temperature of the outdoor environment after the air conditioner 1 is started are detected respectively, and the controller 70 determines the output capacity value of the compressor according to the temperature of the indoor environment and the temperature of the outdoor environment obtained at this time; determines the heat dissipation of the indoor heat source in the indoor environment according to the temperature of the indoor environment and the panoramic infrared image; and corrects the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor to reduce the temperature fluctuation of the indoor environment. Therefore, after the air conditioner 1 is started, the temperature value and area analysis of the infrared image are performed to detect the difference between the indoor heat source and the ambient temperature in real time, calculate the heat dissipation of the indoor heat source, and adjust the compressor frequency, so as to maintain the stability of the indoor environment temperature, ensure the comfort of the user, and also realize the active energy saving function of the compressor.

[0045] In some embodiments, when determining the heat dissipation of an indoor heat source based on the temperature of the indoor environment and a panoramic infrared image, the controller 70 is specifically configured to: divide the panoramic infrared image into N infrared light blocks according to color intervals; wherein each color interval corresponds to an infrared light block; determine the area and surface radiation temperature corresponding to each infrared light block; and determine the heat dissipation of the indoor heat source based on the temperature of the indoor environment, the area and surface radiation temperature of each infrared light block.

[0046] Specifically, if Figure 2 and Figure 3 As shown, after the air conditioner 1 is started, the controller 70 can determine the heat dissipation of the indoor heat source according to the acquired temperature of the indoor environment and the panoramic infrared image, so as to better adjust the temperature of the indoor environment. Specifically, the controller 70 divides the panoramic infrared image into N infrared light blocks according to the color interval, wherein each color interval corresponds to an infrared light block, and each infrared light block represents a different temperature interval. For example, the color block can be warm red, and the temperature interval of the infrared light block corresponding to its color interval can be 20-35 degrees. Therefore, the controller 70 can analyze and process each infrared light block to determine the area and surface radiation temperature corresponding to each infrared light block. In other embodiments, the infrared image acquisition device 40 includes an infrared thermometer, which is specifically composed of an optical system, a photoelectric detector, a signal amplifier and signal processing, a display output and other parts. The optical system gathers the target infrared radiation energy within its field of view, and the size of the area is determined by the optical parts of the thermometer and their positions. The infrared energy focused on the photodetector can be converted into a corresponding electrical signal, which is converted into the temperature value of the measured target after passing through the amplifier and signal processing circuit and corrected according to the algorithm and target emissivity of the instrument. In this way, the infrared image acquisition device can directly output the surface radiation temperature of the infrared light block to the controller 70, which is also within the protection scope of the present invention. Finally, according to the temperature of the indoor environment, the area and surface radiation temperature of each infrared light block, the controller 70 can determine the heat dissipation of the indoor heat source, that is, the heat emitted by the indoor heat source.

[0047] In some embodiments, when determining the heat dissipation of the indoor heat source according to the temperature of the indoor environment, the area of ​​each infrared light block and the surface radiation temperature, the controller 70 is specifically configured as follows:

[0048] Q sum =Q1+Q2+…+Q i +…+Q N ;

[0049]

[0050] Among them, Q sum is the heat dissipation of the indoor heat source, N is the number of infrared light blocks, Q i is the heat dissipation of the ith infrared light block, ε i is the emissivity of the material in the ith infrared light block, Б is the Stefan Polchertz constant, T i is the surface radiation temperature of the ith infrared light block, T indoor is the indoor temperature, S i is the area of ​​the i-th infrared light block.

[0051] Specifically, after the air conditioner 1 is started, Q sum Note that Q is the heat dissipation of the indoor heat source. i Denote the heat dissipation of the ith infrared light block, ε i It is recorded as the emissivity of the material in the ith infrared light block, for example, it can be 0-1. Different materials have different emissivities. B can be recorded as the Steven Polhertz constant. For example, B can be 5.67*10-8w / (m 2 ·k4), T i Denote the surface radiation temperature of the i-th infrared light block, T indoor S is the temperature of the indoor environment. i It is understood that in different indoor environments, after the controller 70 divides the panoramic infrared image into N infrared light blocks according to the color range, different parameters can be brought into the formula Q to determine the heat dissipation of the indoor heat source according to the temperature of the different indoor environments, the area of ​​each infrared light block and the surface radiation temperature. sum =Q1+Q2+…+Q i +…+Q N as well as By performing calculations in the indoor temperature sensor, the heat dissipation of the indoor heat source can be obtained more accurately, so that the controller 70 can more accurately control the air conditioner 1 to reduce temperature fluctuations, maintain indoor temperature stability, and ensure user comfort.

[0052] In some embodiments, after determining the heat dissipation of the indoor heat source based on the temperature of the indoor environment, the area of ​​each infrared light block and the surface radiation temperature, the controller 70 is further configured to correct the heat dissipation of the indoor heat source to obtain a corrected heat dissipation of the indoor heat source.

[0053] Specifically, when determining the heat dissipation of the indoor heat source according to the temperature of the indoor environment, the area of ​​each infrared light block and the surface radiation temperature, there are some factors that may affect the accuracy of the calculation results, including but not limited to the calculation errors of the position, size and shape of the indoor heat source being blocked, etc. By correcting the heat dissipation of the indoor heat source, a more accurate result can be obtained, that is, by correcting the heat dissipation of the indoor heat source, the controller 70 can more accurately control the air conditioner 1 to reduce temperature fluctuations, maintain indoor temperature stability, and ensure user comfort.

[0054] In some embodiments, when correcting the heat dissipation of the indoor heat source, the controller 70 is specifically configured to: multiply the heat dissipation of the indoor heat source by a preset correction coefficient to obtain a corrected heat dissipation of the indoor heat source.

[0055] Specifically, before the heat dissipation of the indoor heat source is corrected, the correction coefficient α can be preset and stored in the controller 70, and the heat dissipation of the indoor heat source after correction is the product of the heat dissipation of the indoor heat source before correction and the correction coefficient α. It can be understood that the correction coefficient α can be an adjustable engineering experience value, which is used to fit the deviation between the theoretical calculation value and the actual measurement value of the heat dissipation of the indoor heat source. That is, the heat dissipation of the indoor heat source can be corrected by the preset correction coefficient α to ensure that the heat dissipation of the indoor heat source has the best applicability and accuracy.

[0056] In some embodiments, when determining the surface radiation temperature corresponding to each infrared light block, the controller 70 is specifically configured to: determine the surface radiation temperature interval corresponding to the infrared light block according to the color interval in which the infrared light block is located; and use the temperature average value corresponding to the surface radiation temperature interval as the surface radiation temperature of the corresponding infrared light block.

[0057] Specifically, in the panoramic infrared image, different color intervals represent different temperature intervals, that is, each color interval corresponds to a certain surface radiation temperature interval. After the air conditioner 1 is started, when the controller 70 determines the surface radiation temperature corresponding to each infrared light block, it can first divide the panoramic infrared image into N infrared light blocks according to the color interval, and then determine the surface radiation temperature interval corresponding to the block according to the color interval in which each infrared light block is located. After determining the surface radiation temperature interval corresponding to the infrared light block, the controller 70 can use the temperature average value of this interval as the surface radiation temperature of the corresponding infrared light block. It can be understood that by determining the surface radiation temperature interval according to the color interval and using the average temperature of the surface radiation temperature interval to determine the surface radiation temperature of the infrared light block, a more accurate calculation of the heat dissipation of the indoor heat source can be achieved, so that the controller 70 can more accurately control the air conditioner 1 to reduce temperature fluctuations, maintain indoor temperature stability, and ensure user comfort.

[0058] In some embodiments, when determining the surface radiation temperature interval corresponding to the infrared light block according to the color interval where the infrared light block is located, the controller 70 is specifically configured as follows: according to the color interval where the infrared light block is located, query a preset color interval-surface radiation temperature interval correspondence mapping table to obtain the surface radiation temperature interval corresponding to the color interval where the infrared light block is located; wherein the color interval-surface radiation temperature interval correspondence mapping table contains at least one set of color interval-surface radiation temperature interval correspondence, and at least one set of color interval-surface radiation temperature interval correspondence includes at least a correspondence between a color interval and a surface radiation temperature interval.

[0059] Specifically, the surface radiation temperature intervals corresponding to different color intervals in the color interval-surface radiation temperature interval correspondence mapping table can be obtained through experimental calibration and pre-stored in the controller. After the air conditioner 1 is started, when the controller 70 determines the surface radiation temperature interval corresponding to the infrared light block according to the color interval where the infrared light block is located, the preset color interval-surface radiation temperature interval correspondence mapping table can be queried according to the color interval where the infrared light block is located to obtain the surface radiation temperature interval corresponding to the color interval where the infrared light block is located. Specifically, in the preset color interval-surface radiation temperature interval correspondence mapping table, the surface radiation temperature interval corresponding to each color interval that is preset is saved. When the controller 70 determines the color interval where a certain infrared light block is located, it will query the preset color interval-surface radiation temperature interval correspondence mapping table to find the surface radiation temperature interval corresponding to the color interval. Among them, the color interval-surface radiation temperature interval correspondence mapping table contains at least one set of color interval-surface radiation temperature interval correspondence, and at least one set of color interval-surface radiation temperature interval correspondence includes at least the correspondence between the color interval and the surface radiation temperature interval, that is, the color interval-surface radiation temperature interval correspondence mapping table can contain one or more sets of color interval-surface radiation temperature interval correspondence, wherein each color interval corresponds to a surface radiation temperature interval.

[0060] In some embodiments, when the target operating frequency of the compressor is corrected according to the heat dissipation of the indoor heat source and the output capacity value of the compressor, the controller 70 is specifically configured as follows:

[0061] F obj =F ope +Q sum / P pre ;

[0062] Among them, F obj is the corrected target operating frequency of the compressor, F ope is the target operating frequency of the compressor before correction, Q sum is the heat dissipation of the indoor heat source, P pre is the output capacity of the compressor.

[0063] Specifically, combined Figure 4 As shown, F obj The corrected compressor target operating frequency, F ope The target operating frequency of the compressor before correction is Q sum Recorded as the heat dissipation of the indoor heat source, P preThus, the controller 70 can substitute the calculated heat dissipation of the indoor heat source, the output capacity of the compressor, and the target operating frequency of the compressor into the formula F obj =F ope +Q sum / P pre The corrected target operating frequency of the compressor can be obtained, wherein the corrected frequency F of the compressor can be calculated according to the heat dissipation of the indoor heat source and the output capacity value of the compressor. rev , that is, F rev =Q sum / P pre In this way, the embodiment of the present invention adjusts the target operating frequency of the compressor according to the heat dissipation of the indoor heat source, so that when the indoor heat source increases, the operating frequency of the compressor is automatically increased, and when the indoor heat source decreases, the operating frequency of the compressor is automatically reduced, thereby achieving the effect of active energy saving of the compressor.

[0064] In some embodiments, when determining the output capacity value of the compressor according to the temperature of the indoor environment and the temperature of the outdoor environment, the controller 70 is specifically configured as follows: according to the indoor environment temperature and the outdoor environment temperature, query a preset indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence mapping table to obtain the output capacity value of the compressor corresponding to the indoor environment temperature and the outdoor environment temperature; wherein the indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence mapping table contains at least one set of indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence, and at least one set of indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence includes at least the correspondence between the indoor environment temperature, the outdoor environment temperature and the compressor output capacity value.

[0065] Specifically, the output capacity values ​​of the compressors corresponding to different indoor ambient temperatures and outdoor ambient temperatures in the indoor ambient temperature-outdoor ambient temperature-compressor output capacity value correspondence mapping table can be obtained through experimental calibration and pre-stored in the controller. After the air conditioner 1 is started, when the controller 70 determines the output capacity value of the compressor according to the temperature of the indoor environment and the temperature of the outdoor environment, the preset indoor ambient temperature-outdoor ambient temperature-compressor output capacity value correspondence mapping table can be queried according to the indoor ambient temperature and the outdoor ambient temperature to obtain the output capacity value of the compressor corresponding to the indoor ambient temperature and the outdoor ambient temperature. Specifically, in the preset indoor ambient temperature-outdoor ambient temperature-compressor output capacity value correspondence mapping table, the output capacity values ​​of the compressors corresponding to the preset temperatures of each indoor environment and the outdoor environment are stored. When the controller 70 determines the temperature of the current indoor environment and the temperature of the outdoor environment, it will query the preset indoor ambient temperature-outdoor ambient temperature-compressor output capacity value correspondence mapping table to find the output capacity value of the compressor corresponding to the temperature of the indoor environment and the temperature of the outdoor environment. Among them, the indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence mapping table contains at least one set of indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence, and at least one set of indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence includes at least the correspondence between the indoor environment temperature, the outdoor environment temperature and the compressor output capacity value, that is, the indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence mapping table may contain one or more sets of indoor environment temperature-outdoor environment temperature-compressor output capacity value correspondence, wherein each indoor environment temperature and outdoor environment temperature correspond to a compressor output capacity value. For example, if the current indoor environment temperature can be 25°C and the outdoor environment temperature can be 30°C, the controller 70 queries the mapping table and finds that the compressor output capacity value corresponding to this temperature condition can be 200W; if the current indoor environment temperature can be 27°C and the outdoor environment temperature can be 30°C, the controller 70 queries the mapping table and finds that the compressor output capacity value corresponding to this temperature condition can be 300W.

[0066] In some embodiments, after correcting the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor, the controller 70 is further configured to: determine whether the temperature of the indoor environment reaches a preset temperature range; when it is determined that the temperature of the indoor environment reaches the preset temperature range, control the compressor to operate according to the current target operating frequency; when it is determined that the temperature of the indoor environment does not reach the preset temperature range, return to execute the step of correcting the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor to reduce the temperature fluctuation of the indoor environment, until the temperature of the indoor environment reaches the preset temperature range.

[0067] Specifically, after the air conditioner 1 is started, the controller 70 can correct the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor, and during the correction process, the controller 70 can obtain the indoor ambient temperature detected by the indoor temperature sensor 50 in real time, and adjust the target operating frequency of the compressor according to the adaptability of the indoor ambient temperature to reduce the temperature fluctuation of the indoor environment, thereby achieving a better temperature control effect, ensuring the comfort of the user and the energy saving of the compressor. Specifically, the controller 70 can determine whether the temperature of the indoor environment reaches the preset temperature range. When the controller 70 determines that the temperature of the indoor environment reaches the preset temperature range, the compressor is controlled to operate according to the current target operating frequency; when the controller 70 determines that the temperature of the indoor environment does not reach the preset temperature range, it returns to execute the step of correcting the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor to reduce the temperature fluctuation of the indoor environment until the temperature of the indoor environment reaches the preset temperature range.

[0068] Furthermore, the controller 70 can obtain the temperature of the indoor environment, the temperature of the outdoor environment, and the panoramic infrared image at preset intervals, determine the output capacity value of the compressor according to the temperature of the indoor environment and the temperature of the outdoor environment, determine the heat dissipation of the indoor heat source in the indoor environment according to the temperature of the indoor environment and the panoramic infrared image, and thereby correct the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor, that is, adjust the operating frequency of the compressor according to the heat load of the indoor heat source at preset intervals, such as 1 hour, to actively increase the heating amount when the heat source increases to reduce the indoor environment temperature fluctuation; when the heat source decreases, reduce the compressor frequency to achieve active energy saving. When the compressor frequency is adjusted so that the indoor environment temperature reaches the set value stable interval, the current control parameters are maintained for continuous operation; when the indoor environment temperature does not reach the set value stable interval, repeat the adjustment process of correcting the target operating frequency of the compressor according to the heat dissipation of the indoor heat source and the output capacity value of the compressor until the compressor operating parameters match the heat load of the indoor heat source.

[0069] As a specific embodiment, the following Figure 5 As shown, the overall control process of the air conditioner 1 according to the embodiment of the present invention is illustrated.

[0071] Step S11, the air conditioner is turned on and runs.

[0072] Step S12: the infrared image acquisition device performs indoor infrared panoramic scanning at a fixed period.

[0073] Step S13, analyzing the image, outputting the area S of each infrared light block, the surface radiation temperature T of the heat source, the temperature T of the indoor environment, and the indoor .

[0074] Step S14, calculate the compressor correction frequency F according to the preset parameters and formula of the control module rev .

[0075] Step S15, correcting the compressor target frequency F obj , detect the indoor ambient temperature change trend, and determine whether the temperature of the indoor environment reaches the set temperature stability range. If so, execute step S16, if not, execute step S17.

[0076] Step S16: the temperature of the indoor environment reaches the set temperature stable range, the current parameters are maintained, and the system continues to operate.

[0077] Step S17: If the temperature of the indoor environment does not reach the set temperature stable range, the adjustment process is repeated.
