In the description of the present application, the meaning of "plurality" is at least two, for example two, three, unless explicitly defined otherwise.
Referring to fig. 1 and 2, an embodiment of the present application provides a control method, including:
step 01: detecting the concentration of a refrigerant in a current scene;
specifically, the refrigerant, commonly known as snow, is a working fluid used for transferring heat energy in refrigeration equipment (such as air conditioner) and the like to generate a refrigeration effect. The current domestic heating device is widely applied to the requirements of carrying the refrigerating device at the same time, along with the development of the age, the requirements of people on environment protection are higher and higher in recent years, and the refrigerating device is used as a novel environment-friendly refrigerant (such as R32, 454b and the like) which is more environment-friendly, for example, can reduce ozone consumption and is beneficial to improving the global warming problem. However, the novel environment-friendly refrigerant has high inflammability, and once leakage occurs, the problem of fire possibly occurs, so that great potential safety hazard is brought. Therefore, the refrigerant concentration of the current scene can be detected in real time, and the problem of refrigerant leakage can be found in time.
Step 02: under the condition that the concentration of the refrigerant is larger than the preset concentration, controlling the electric appliance 20 related to the refrigerant to enter a preset operation condition, wherein the electric appliance 20 comprises at least one of refrigeration equipment 21, heating equipment 22 and a fan 23.
Specifically, referring to fig. 2, the control method of the present application may be applied to an electrical system 100, where the electrical system 100 includes an electrical device 20 associated with a refrigerant. The electric appliance 20 related to the refrigerant can be a refrigerating device 21 using the refrigerant or a heating device 22 possibly igniting the refrigerant, or a fan 23 for reducing the concentration of the refrigerant in the current scene.
During normal operation of the refrigeration unit 21, there may be a slight leakage of refrigerant, which may be diluted with air flow very quickly, without a substantial safety hazard. Only if the refrigerant concentration is larger than a certain concentration, the refrigerant in the current scene can be determined to be abnormal leakage caused by the damage of the refrigerant pipeline and the like, and the occurrence of the refrigerant leakage can be determined at the moment, so that the safety control is needed.
Therefore, a preset concentration can be set according to the concentration of the refrigerant in the scene, and when the concentration of the refrigerant in the current scene is detected to be larger than the preset concentration, the leakage of the refrigerant is confirmed. Then, the electric appliance 20 related to the refrigerant is controlled to enter a preset operation working condition, for example, the refrigerating equipment 21 and/or the heating equipment 22 are controlled to stop operation, so that the refrigerant is prevented from being ignited by the operation of the refrigerating equipment 21 and the heating equipment 22, or the fan 23 is controlled to start, so that the concentration of the refrigerant in the current scene is reduced, the control of the electric appliance 20 aiming at the problem of refrigerant leakage is completed, the refrigerant is prevented from being further leaked, and the potential safety hazard caused by the refrigerant leakage is avoided.
The control method of the embodiment of the present application detects the refrigerant concentration of the current scene in real time first, and discovers the problem of refrigerant leakage in time, and can confirm that the refrigerant leaks under the condition that the refrigerant concentration is greater than the preset concentration, at this time, aiming at the refrigerant leakage problem, the electric appliance 20 related to the refrigerant is controlled to enter the preset operation working condition, for example, the operation of the refrigeration equipment 21 and/or the heating equipment 22 is stopped, the operation of the fan 23 is controlled to reduce the refrigerant concentration, so as to prevent the refrigerant from further leakage, and avoid the potential safety hazard caused by the refrigerant leakage, so that the electric appliance system 100 is safer and more reliable.
Referring to fig. 3, in some embodiments, step 01: detecting the refrigerant concentration of the current scene, comprising:
step 011: and detecting infrared energy of a wave band corresponding to the refrigerant to determine the concentration of the refrigerant.
Specifically, the electrical system 100 further includes a refrigerant leak detector 30, where the refrigerant leak detector 30 can be used to detect the refrigerant concentration in the current scenario. The core components of the coolant leak detector 30 include an infrared absorption filter comprising an emitter and an infrared energy detector, with a sampling unit of the filter therebetween. The infrared energy is a portion of the electromagnetic energy spectrum and most materials absorb infrared energy in a specific and known band, with the specific band of energy absorbed by the material being referred to as its absorption spectrum. All refrigerants have similar absorption spectra, ranging from 7.5 to 14 microns.
The emitter may generate a high intensity integrated infrared spectrum energy stream comprising all of the wavelength bands, and the filter may block all infrared spectrum energy streams outside of the refrigerant absorption spectrum when the high intensity integrated infrared spectrum energy stream passes through the filter. The infrared spectral energy stream after the filter treatment may strike the infrared energy detector, causing the infrared energy detector to heat. When the refrigerant leaks in the current scene, some infrared energy in the infrared spectrum energy flow processed by the filter can be absorbed by the refrigerant, so that the infrared energy reaching the infrared energy detector is reduced, and accordingly the temperature of the infrared energy detector is reduced, and the concentration of the refrigerant can be determined by detecting the infrared energy of a wave band corresponding to the refrigerant.
Further, in addition to the refrigerant leakage detection device 30, there are other methods for determining whether the refrigerant leaks, for example, whether the refrigerant leaks may be determined by detecting the air pressure of the pipeline in which the refrigerant is located. When the refrigerant is not leaked, the air pressure of the pipeline where the refrigerant is located is a stable value, and when the refrigerant leaks from the pipeline, the air pressure of the pipeline where the refrigerant is located can suddenly drop. In the operation process of the refrigeration equipment 21, a slight refrigerant leakage may exist, so when the pressure drop amplitude of the pipeline where the refrigerant is located is small, the refrigerant leakage is considered to be only slight when the refrigeration equipment 21 is in normal operation, and the electric appliance 20 related to the refrigerant is not required to be controlled according to the situation. When the pressure drop of the pipeline where the refrigerant is located is large, the refrigerant leakage can be confirmed, and at the moment, the electric appliance 20 related to the refrigerant needs to be controlled to enter the preset operation condition. Therefore, a preset air pressure can be set according to the air pressure of the corresponding pipeline in which the refrigerant is located when the refrigerant leaks, and when the air pressure of the pipeline in which the refrigerant is located is smaller than the preset air pressure, the refrigerant leakage is determined, and the electric appliance 20 related to the refrigerant is controlled to enter the preset operation condition.
Therefore, whether the refrigerant leaks or not can be determined according to the detection of the infrared energy of the wave band corresponding to the refrigerant, or the detection of the air pressure of the pipeline in which the refrigerant is positioned, or other methods, so that when the refrigerant leaks, the refrigerant leakage is timely found out, the electric appliance 20 related to the refrigerant is controlled to enter a preset operation working condition, the refrigerant is prevented from further leakage, and the potential safety hazard caused by the refrigerant leakage is avoided.
Referring to fig. 2 and 4, in some embodiments, the electric appliance 20 includes a cooling device 21 and a heating device 22, and the preset operation condition includes stopping operation, step 02: controlling the electric appliance 20 related to the refrigerant to enter a preset operation condition includes:
step 021: the refrigerating apparatus 21 and the heating apparatus 22 are controlled to stop operating.
Specifically, the refrigeration device 21 may use a new environment-friendly refrigerant (e.g., R32, 454b, etc.) as the refrigerant to perform refrigeration. However, the novel environment-friendly refrigerant has high flammability, and in the refrigerating process of the refrigerating device 21, if the novel environment-friendly refrigerant leaks, the condition that the refrigerant is ignited may occur. In the heating process, the heating device 22 (such as a gas furnace) may generate an open flame or make the ambient temperature reach the ignition point of the novel environment-friendly refrigerant, so as to cause the novel environment-friendly refrigerant to be ignited, thereby causing a fire hazard. Therefore, when the concentration of the refrigerant is greater than the preset concentration, that is, when the cold coal leaks, the operation of the refrigeration equipment 21 and the heating equipment 22 is controlled to stop, so that potential safety hazards caused by the operation of the refrigeration equipment 21 and the heating equipment 22 when the refrigerant leaks are avoided.
Referring to fig. 2 and 5, in some embodiments, step 021: controlling the cooling device 21 and the heating device 22 to stop operation may include:
step 0211: the transmission of the cooling signal to the cooling device 21 is stopped and the transmission of the heating signal to the heating device 22 is stopped.
Specifically, the electrical system 100 further includes a controller 40, the controller 40 controlling the operating conditions of the electrical appliance 20 by sending control signals, wherein the control signals include a cooling signal and a heating signal. When the cooling is required, the controller 40 sends a cooling signal to the cooling device 21, the cooling device 21 receiving the cooling signal starts to operate, and when the cooling device 21 does not receive the cooling signal, the cooling device 21 stops operating. Similarly, when heating is required, the controller 40 sends a heating signal to the heating device 22, the heating device 22 starts ignition, and when the heating device 22 receives the heating signal, the heating device 22 stops operating.
Accordingly, the controller 40 continuously transmits control signals to the cooling apparatus 21 and the heating apparatus 22 when the heating apparatus 22 and the cooling apparatus 21 are operating normally. In contrast, when the refrigerant leaks, it is necessary to control the operation of the refrigeration equipment 21 to stop in order to prevent further leakage of the refrigerant, and to control the operation of the heating signal to stop in order to prevent the leaked refrigerant from being ignited. Then, when the refrigerant leaks, the controller 40 only needs to stop sending the refrigeration signal to the refrigeration equipment 21 and stop sending the heating signal to the heating equipment 22, so that the refrigeration equipment 21 and the heating equipment 22 can stop running, further leakage of the refrigerant is prevented, and potential safety hazards caused by the leakage of the refrigerant are avoided.
Further, the number of controllers 40 may be one or more. In one embodiment, each appliance 20 has a corresponding controller 40, e.g., each appliance 20 includes an independent controller 40. In another embodiment, the plurality of electric appliances 20 are controlled by the same controller 40, for example, the heating device 22 further includes the controller 40, and the controller 40 of the heating device 22 can be used to send signals to the heating device 22 and the cooling device 21 to control the operation conditions of the heating device 22 and the cooling device 21, so as to ensure the normal operation of the cooling device 21 and the heating device 22, and facilitate the unified stopping of the operation of the heating device 22 and the cooling device 21 by the controller 40 when the refrigerant leaks, in addition, the installation space of the electric appliance system 100 can be saved by using one controller 40 to control the plurality of electric appliances, so that the structural layout of the electric appliance system 100 is more compact.
Still further, the electrical system 100 may include an indoor unit and an outdoor unit, such as for an air conditioner in the refrigeration appliance 21, an air conditioning indoor unit and an air conditioning outdoor unit. The indoor unit is mainly a device installed indoors (as indicated by a dotted line frame S1 in fig. 2), and the outdoor unit is mainly a device installed outdoors (as indicated by a dotted line frame S2 in fig. 2), wherein the controller 40 may be provided indoors or outdoors, without limitation.
Referring to fig. 2, in some embodiments, in the case where the refrigeration apparatus 21 does not receive the refrigeration signal, the compressor of the refrigeration apparatus 21 stops running, and/or the safety shut-off valve of the refrigeration apparatus 21 is closed; in the event that the heating device 22 does not receive the heating signal, the heating device 22 ceases to fire and/or the gas valve of the heating device 22 closes.
Specifically, the refrigerating apparatus 21 may include a compressor for refrigerating by compressing a refrigerant, and a safety cut-off valve provided in a line where the refrigerant is located to control a flow of the refrigerant. When the refrigeration equipment 21 needs to refrigerate, the compressor is operated, and the safety cut-off valve is opened, so that the refrigerant continuously flows to the compressor. When the refrigerant leaks, the pipeline where the refrigerant is located may be damaged, if the compressor continues to operate, the refrigerant will continue to flow, so that more refrigerant leaks out from the damaged part of the pipeline, and when the compressor operates, if the refrigerant is insufficient, a certain adverse effect is brought to the compressor, for example, overheat, thermal protection or operation load of the compressor becomes large. In addition, sparks may occur when the compressor is started, and if the compressor is started after the refrigerant leaks, the refrigerant may be ignited. Therefore, when detecting the refrigerant leakage, the controller 40 stops sending the refrigeration signal to the refrigeration equipment 21, and under the condition that the refrigeration equipment 21 cannot receive the refrigeration signal, the compressor of the refrigeration equipment 21 can stop running to ensure that the compressor of the refrigeration equipment 21 stops running and reduce the damage of the compressor of the refrigeration equipment 21, and meanwhile, the safety cut-off valve of the refrigeration equipment 21 can be closed to ensure that the refrigerant in the pipeline where the refrigerant is located cannot continue flowing, thereby preventing the refrigerant from further leakage.
The heating apparatus 22 may include an ignition device and a gas valve disposed in a line where the gas is located to control the flow of the gas. When heating is required, the heating device 22 opens the gas valve and the ignition device to cause the ignition device to ignite the gas to complete heating. However, if the refrigerant leaks during the operation of the heating device 22, the ignition device may also ignite the leaked refrigerant, the open flame generated during the combustion of the gas may also ignite the leaked refrigerant, and the heat generated during the combustion of the gas may be emitted to the surroundings, if the heat of a certain place near the heating device 22 is too high, the temperature of the place reaches the ignition point of the refrigerant, and at this time, the refrigerant may be ignited. Therefore, when detecting the leakage of the refrigerant, the controller 40 also stops sending the heating signal to the heating device 22, and if the heating device 22 does not receive the heating signal, the ignition is stopped, and/or the gas valve of the heating device 22 is closed, so as to avoid the generation of open fire or further increase of the ambient temperature, thereby preventing the leaked refrigerant from being ignited. In the case where the heating device 22 does not ignite the fuel gas to burn, only ignition may be stopped, and in the case where the heating device 22 ignites the fuel gas to burn, it is necessary to stop the fuel gas and close the fuel gas valve to prevent the refrigerant from being ignited.
Referring to fig. 2 and 6, in some embodiments, the refrigeration device 21 performs refrigeration by receiving the refrigeration signal of the temperature controller 41, and the heating device 22 performs heating by receiving the heating signal of the temperature controller 41, step 021: controlling the refrigerating apparatus 21 and the heating apparatus 22 to stop operating may further include:
step 0212: the power interface of the temperature controller 41 is disconnected.
Specifically, the controller 40 may be a temperature controller 41, where the temperature controller 41 may control the cooling device 21 and the heating device 22 to implement temperature control, for example, when cooling is required, the temperature controller 41 may send a cooling signal to the cooling device 21 to make the cooling device 21 operate and complete cooling, and when heating is required, the temperature controller 41 may send a heating signal to the heating device 22 to make the heating device 22 operate and complete heating.
The refrigerating device 21 and the heating device 22 can continuously operate only when continuously receiving the control signal, so that in the case of refrigerant leakage, the power interface of the temperature controller 41 can be disconnected, the temperature controller 41 can stop operating, a refrigerating signal can not be sent to the refrigerating device 21, and a heating signal can not be sent to the heating device 22, so that the refrigerating device 21 and the heating device 22 stop operating, the refrigerant can not be further leaked, and the heating device 22 can not ignite the refrigerant.
Further, the temperature controller 41 may be powered by a certain electric appliance 20, for example, by connecting a power interface of the heating device 22 and a power interface of the temperature controller 41 together, and powering the temperature controller 41 by the heating device 22. When the refrigerant leaks, the power interface of the temperature controller 41 is disconnected through the heating device 22, so that the temperature controller 41 can be controlled to be closed, and the refrigerating signal and the heating signal are not emitted any more, thereby indirectly controlling the stopping of refrigerating and heating.
In other embodiments, the controller 40 includes a temperature controller 41 and a controller 40 of the heating device 22, the temperature controller 41 is configured to send a cooling signal to control the operation of the cooling device 21, and the controller 40 of the heating device 22 is configured to send a heating signal to control the operation of the heating device. When the refrigerant leaks, the refrigerating apparatus 21 is controlled to stop operating by the temperature controller 41, and the heating apparatus is controlled to stop operating by the controller 40 of the heating apparatus 22. In particular, if the power interface of the heating apparatus 22 and the power interface of the temperature controller 41 are connected together at this time, the controller 40 of the heating apparatus 22 may stop the operation of the heating apparatus 22 by stopping the transmission of the heating signal to the heating apparatus 22 on the one hand, and stop the operation of the cooling apparatus 21 by turning off the power interface of the temperature controller 41 on the other hand.
In this way, the controller 40 can control the operation and stop of the refrigerating device 21 and the heating device 22, so that the refrigerating device 21 and the heating device 22 can be timely stopped when the refrigerant leaks, and accidents are prevented.
Referring to fig. 2 and 7, in some embodiments, the electric appliance 20 further includes a fan 23, and the preset operation condition includes operating in a preset gear, step 02: controlling the electric appliance 20 related to the refrigerant to enter a preset operation condition may further include:
step 022: the fan 23 is controlled to operate in a preset gear.
Specifically, the electric appliance 20 further includes a fan 23, and the fan 23 can be used to dilute the concentration of the refrigerant leaked from the air. The fan 23 may be an electrical apparatus 20 separately disposed in the electrical apparatus system 100, and the fan 23 may be disposed in the electrical apparatus 20 related to the refrigerant, for example, the heating device 22 may include the fan 23, and the cooling device 21 may also include the fan 23. The fan 23 can operate in different gear positions, and when the refrigerant leaks, the fan 23 is required to operate in a larger gear position so as to accelerate the speed of diluting the concentration of the leaked refrigerant, reduce the concentration of the refrigerant and prevent potential safety hazards caused by the leaked refrigerant. Thus, the preset operating conditions of the blower 23 include operating in accordance with a preset gear, and the preset gear is a larger gear. When detecting the refrigerant leakage, the controller 40 may send a gear control signal to the fan 23 to control the fan 23 to operate according to a preset gear, for example, control the fan 23 to operate at a maximum gear, it can be understood that the higher the gear of the fan 23, the greater the wind power, the faster the speed of reducing the concentration of the refrigerant in the scene, and the fan 23 operates at the maximum gear, so that the concentration of the refrigerant in the scene can be reduced below the preset concentration in the shortest time.
Further, the refrigerant concentration of the current scene can be detected in real time, and the gear of the fan 23 can be adjusted according to the refrigerant concentration. For example, when the refrigerant concentration is detected to be high, the fan 23 is controlled to operate in the maximum gear to increase the rate of the concentration of the diluted leaked refrigerant as much as possible, and when the refrigerant concentration is low, the fan 23 is controlled to operate in the smaller gear to reduce the power consumption when the fan 23 operates.
Referring to fig. 8, in some embodiments, the control method may further include:
step 03: and under the condition that the concentration of the refrigerant is larger than the preset concentration, sending out prompt information and entering a non-volatile locking state.
Specifically, when detecting the leakage of the refrigerant, the electrical system 100 may send out a prompt message in addition to controlling the electrical apparatus 20 related to the refrigerant to enter the preset operation condition, so as to prompt the user to process the leakage of the refrigerant in time, and avoid the potential safety hazard caused by the leakage of the refrigerant. At this time, the electrical system 100 also enters a non-volatile locking state, which is a safe off state of the electrical system 100, and in this state, the restarting can only be achieved by manual reset by the user, so as to ensure that the refrigerating device 21 and the heating device 22 cannot be restarted automatically, and the refrigerating device 21 and the heating device 22 can be restarted only after the user confirms that the refrigerant leakage problem is solved, so that the refrigerant cannot leak further before the refrigerant leakage problem is not solved, and the potential safety hazard caused by the refrigerant leakage is further prevented.
For example, the electrical system 100 may include a speaker, and in the case of leakage of the refrigerant, the speaker may emit a prompt sound, such as a dripping sound, a buzzing sound, etc., and the prompter may also emit a prompt voice to prompt the user to deal with measures of refrigerant leakage, such as the prompt voice "please turn on the fan 23, turn off the gas furnace, and the air conditioner". Alternatively, the electrical system 100 may include an indicator light that may emit a warning light, such as a continuous red light, a red flashing light, etc., in the event of a refrigerant leak.
