Description

Technical Field

[0002] This section merely provides background information related to the present application and is not necessarily prior art.

[0003] In some technologies, some air conditioners can automatically adjust the fan position (wind speed) of the internal fan according to the difference between the target temperature and the real-time indoor temperature. This method has a limited control effect on the cooling or heating of the air conditioner, and cannot quickly control the indoor temperature, and does not truly achieve the control effect.

For example, when the difference between the target temperature and the real-time indoor temperature, that is, the current temperature of the indoor environment, is large, if the indoor unit changes the fan gear while simultaneously increasing the output frequency of the compressor, the difference between the target temperature and the real-time indoor temperature can be quickly reduced. On the contrary, when the difference between the target temperature and the real-time indoor temperature is small, if the indoor unit reduces the fan gear while simultaneously reducing the output frequency of the compressor, it can effectively avoid temperature shutdown, reduce energy consumption, and improve comfort.

[0009] In addition, the control method of the air conditioning system according to the present application may also have the following additional technical features:

[0025] In some embodiments of the present invention, the current comfort parameter is the current temperature T1, and the absolute value of the difference between the target temperature Tes and the current temperature T1 is positively correlated with the target temperature adjustment coefficient K.

[0026] In some embodiments of the present invention, when the absolute value of the difference between the target temperature Tes and the current temperature T1 is greater than or equal to the first temperature B1, the target temperature adjustment coefficient K1;

[0027] When the absolute value of the difference between the target temperature Tes and the current temperature T1 is less than the second temperature B2 and greater than the first temperature B1, the target temperature adjustment coefficient K2, K2 is less than K1, and the second temperature B2 is less than the first temperature B1;

[0028] When the absolute value of the difference between the target temperature Tes and the current temperature T1 is less than or equal to the second temperature B2, the target temperature adjustment coefficient K3 is smaller than K2.

[0044] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0045] For ease of description, spatial relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0046] The air-conditioning system can be a household air-conditioning system or a central air-conditioning system. The air-conditioning unit of the air-conditioning system includes an indoor unit and an outdoor unit. The indoor unit includes an indoor heat exchanger, and the indoor unit is usually installed indoors. The outdoor unit includes an outdoor heat exchanger, and the outdoor unit is usually installed outdoors. The indoor unit and the outdoor unit work together to realize the cooling, heating, dehumidification and air purification functions of the air conditioner to achieve comfortable air quality.

[0047] In the air conditioning unit of the central air conditioner, there is usually one outdoor unit, and the number of indoor units can be multiple. Each indoor unit is provided with one or more air outlets to discharge the cooled, heated, dehumidified or purified air into the room through the air outlets. An indoor heat exchanger is usually provided in the indoor unit, and an outdoor heat exchanger is usually provided in the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger are usually connected through a refrigerant pipeline, so that the refrigerant can flow between the indoor heat exchanger and the outdoor heat exchanger.

[0048] During the cooling process of the air-conditioning system, the indoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, takes away the heat in the air in the indoor unit, and then makes the air discharged from the indoor unit the air after heat release and cooling, and the indoor unit blows cold air. At the same time, the outdoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the outdoor unit flowing through the condenser, so that the air in the outdoor unit brings the heat of the condenser to the outside of the outdoor unit, realizing the cooling process.

[0049] During the heating process of the air-conditioning system, the outdoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and replaces the heat carried by the air in the outdoor unit with the refrigerant in the evaporator. At the same time, the indoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the indoor unit flowing through the condenser, so that the air in the indoor unit takes away the heat carried by the condenser and discharges it from the indoor unit to the room outside the indoor unit, so that the indoor unit blows hot air, thereby realizing the heating process.

[0050] The air conditioning system also includes compressors, throttling components (such as expansion valves), etc. In order to reduce indoor noise, the compressor and throttling components can usually be set outdoors. The compressor, throttling components and outdoor heat exchangers and other components set outdoors can be collectively referred to as outdoor units. In the case of an air conditioning system that can both cool and heat, the air conditioning system also includes parts such as a four-way valve to achieve the switching of the air conditioning system between cooling mode and heating mode.

[0051] It should be noted that the air conditioning system may be a structure in which the outdoor unit and the indoor unit are separately arranged, or may be an integrated structure of the indoor and outdoor units. In the case of the air conditioning system having an integrated structure of the indoor and outdoor units, the entire air conditioning system may be arranged outdoors.

[0052] The air conditioning system may also include a gateway for communicating with the outside world, which may receive external commands, requests, and other control target parameters.

[0053] Furthermore, the air conditioning system may also have a sensor for detecting the indoor environment, such as a temperature sensor, a humidity sensor, an air conditioning quality sensor, etc. The air conditioning system may also have a sensor for detecting the outdoor environment, such as a temperature sensor, a humidity sensor, an air conditioning quality sensor, etc.

[0054] In some technologies, some air conditioners can automatically adjust the fan gear (wind speed) of the indoor unit according to the difference between the target temperature and the real-time indoor temperature. This method has a limited control effect on the cooling or heating of the air conditioner, and cannot quickly control the indoor temperature, and does not truly achieve the control effect.

[0055] In order to alleviate the above problems, Figures 1 to 5 As shown, the present application proposes a control method for an air-conditioning system. When the fan gear of the indoor unit is switched, the operating parameters of the compressor of the air-conditioning system can be adjusted. In this way, the fan gear of the indoor unit can be assisted by controlling the compressor to achieve the target comfort parameters more quickly, thereby improving the responsiveness of the air-conditioning system to the control of the comfort parameters.

[0056] like Figure 1 As shown, the control method of the air conditioning system of the present application includes:

[0057] Step 101: Obtain fan gear switching information of an indoor unit of an air-conditioning system.

[0058] Among them, the fan gear switching information can indicate whether the fan of the indoor unit has switched gears. Specifically, the fan gear switching information can be directly a signal of the fan gear switching, or it can be information related to the fan gear switching judgment. Based on this information, it can be inferred whether the fan gear has switched.

[0059] The switching of the fan gear of the indoor unit may also be a control instruction issued by the user, and the air conditioning system controls the switching of the fan gear of the indoor unit based on the control instruction. In this case, the control instruction issued by the user can be used as the information for switching the fan gear. The switching of the fan gear of the indoor unit may also be a control automatically made by the controller of the air conditioning system based on judgment, that is, the air conditioning system automatically implements the fan gear switching based on the control program. In a specific implementation, the control method of the air conditioning system also includes: obtaining the target comfort parameters of the current indoor unit and the current comfort parameters of the indoor environment; adjusting the fan gear of the indoor unit according to the difference between the target comfort parameters and the current comfort parameters.

[0060] The comfort parameter is the parameter expected by the user in the current operation mode of the air conditioner. Specifically, when the air conditioner system is in cooling mode or heating mode, the comfort parameter may be the indoor temperature parameter; when the air conditioner system is in dehumidification mode, the comfort parameter may be the indoor humidity parameter; when the air conditioner system is in purification mode, the comfort parameter may be the indoor air quality parameter. The comfort parameter of the air conditioner system in the current operation state can be obtained through the relevant sensors of the air conditioner system. For example, when the air conditioner system is in cooling mode or heating mode, the indoor temperature parameter can be obtained through the temperature sensor of the indoor unit.

[0061] Taking the cooling mode as an example, the comfort parameters are mainly temperature parameters. The current comfort parameters are also the current temperature of the indoor environment (real-time indoor temperature), and the target comfort parameters are also the target temperature expected or set by the user. When the target temperature is low and the current temperature of the indoor environment is high, that is, the indoor temperature is significantly different from the target temperature, the fan gear can be adjusted to a higher level; when the indoor temperature is significantly different from the target temperature, the fan gear can be adjusted to a lower level.

[0062] When the fan gear is automatically adjusted according to the difference between the current temperature of the indoor environment and the target temperature, the fan gear switching information may include the mapping relationship between the current temperature of the indoor environment, the target temperature and the fan gear. In this way, when the current temperature and the target temperature of the indoor environment are known, the fan gear and whether the fan gear is switched can be known.

[0063] Step 102: Instructing the indoor unit to switch the fan gear according to the fan gear switching information, and adjusting the working parameters of the compressor of the air-conditioning system.

[0064] The operating parameters of the compressor may include frequency, power, speed, etc.

[0065] It is understandable that adjusting the working parameters of the compressor of the air-conditioning system is to make the compressor adapt to the heat exchange capacity required by the current fan gear switching. In the case of fan gear switching, the fan of the indoor unit will respond to the request of the fan gear switching and perform corresponding control operations to increase or decrease the heat exchange capacity of the indoor unit. The adaptive control of the compressor should be consistent with the power change trend of the air-conditioning system caused by the fan gear switching. For example, the fan gear switching reduces the fan gear of the indoor unit, and the heat exchange capacity of the air-conditioning system required is reduced. At this time, the compressor can reduce the operating frequency.

[0066] Specifically, the higher the gear of the fan of the indoor unit is, the stronger the heat exchange capacity of the indoor unit is. Based on this, step S102, instructing the fan gear of the indoor unit to switch according to the fan gear switching information, and adjusting the working parameters of the compressor of the air-conditioning system, may include: instructing the fan gear of the indoor unit to increase according to the fan gear switching information, and controlling the operating frequency of the compressor to increase; instructing the fan gear of the indoor unit to decrease according to the fan gear switching information, and controlling the operating frequency of the compressor to decrease.

[0067] According to the control method of the air-conditioning system of the present application, when the fan gear of the indoor unit is switched, the working parameters of the compressor of the air-conditioning system can be adjusted, so that the fan gear of the indoor unit can be assisted by the control of the compressor to reach the target comfort parameter more quickly, thereby improving the responsiveness of the air-conditioning system to the control of the comfort parameter. For example, when the difference between the target temperature and the real-time indoor temperature, that is, the current temperature of the indoor environment, is large, if the indoor unit changes the fan gear while simultaneously increasing the output frequency of the compressor, the difference between the target temperature and the real-time indoor temperature can be quickly reduced. On the contrary, when the difference between the target temperature and the real-time indoor temperature is small, if the indoor unit reduces the fan gear while simultaneously reducing the output frequency of the compressor, it can effectively avoid temperature shutdown, reduce energy consumption, and improve comfort.

[0068] In one embodiment, step S102 instructs the indoor unit to switch the fan gear according to the fan gear switching information, and adjusts the working parameters of the compressor of the air conditioning system, such as Figure 2 As shown, it may include:

[0069] Step S201: instructing the indoor unit to switch the fan gear according to the fan gear switching information, and obtaining the current operation mode of the air-conditioning system.

[0070] The current operation mode of the air conditioning system may be a cooling mode, a heating mode, a dehumidification mode, a purification mode, etc.

[0071] Step S202: According to the current operation mode of the air-conditioning system, the target comfort parameter of the indoor unit is corrected to determine the corrected target comfort parameter, where the target comfort parameter is the comfort parameter corresponding to the current operation mode.

[0072] Step S203: adjusting the operating parameters of the compressor of the air-conditioning system according to the modified target comfort parameter.

[0073] In a specific embodiment, the current operation mode is the cooling mode, the target comfort parameter is the target temperature Tes, the current comfort parameter is the current temperature, the modified target comfort parameter is the modified target temperature Tes1, and the modified target temperature satisfies the following relationship:

[0074] Tes1=Tes-δt,where

[0075] Among them, δt is the temperature correction value, temperature N is the total number of gears of the indoor unit fan, N is a positive integer; K is the target temperature adjustment coefficient, H t is the fan gear of the indoor unit at the current moment, H t-1 It is the fan gear position of the indoor unit at the last moment.

[0076] In another specific embodiment, the current operation mode is the heating mode, the target comfort parameter is the target temperature Tes, the current comfort parameter is the current temperature, the modified target comfort parameter is the modified target temperature Tes2, and the modified target temperature satisfies the following relationship:

[0077] Tes2=Tes+δt,where

[0078] Among them, δt is the temperature correction value, temperature N is the total number of gears of the indoor unit fan, N is a positive integer greater than 2; K is the target temperature adjustment coefficient, H t is the fan gear of the indoor unit at the current moment, H t-1 It is the fan gear position of the indoor unit at the last moment.

[0079] It should be noted that when the absolute value of δt calculated by the above formula is less than 0.5°C, it is taken as 0.5°C.

[0080] It can be understood that this embodiment combines the indoor temperature T1, the target temperature Tes, and the fan gear change to intelligently calculate the target evaporation and condensation temperature correction value δt, so as to achieve reasonable correction of the target evaporation and condensation temperatures.

[0081] The determination of the target temperature adjustment coefficient K can be adjusted in real time according to the difference between the target temperature and the ambient temperature to achieve more accurate and rapid control. Specifically, in cooling mode and heating mode, the current comfort parameter is the current temperature T1, and the absolute value of the difference between the target temperature Tes and the current temperature T1 is positively correlated with the target temperature adjustment coefficient K.

[0082] In one implementation, the absolute value of the difference between the target temperature Tes and the current temperature T1 can correspond to a target temperature Tes within a certain interval. For example, when the absolute value of the difference between the target temperature Tes and the current temperature T1 is greater than or equal to the first temperature B1, the target temperature adjustment coefficient is K1; when the absolute value of the difference between the target temperature Tes and the current temperature T1 is less than the second temperature B2 and greater than the first temperature B1, the target temperature adjustment coefficient is K2, K2 is less than K1, and the second temperature B2 is less than the first temperature B1. When the absolute value of the difference between the target temperature Tes and the current temperature T1 is less than or equal to the second temperature B2, the target temperature adjustment coefficient is K3, and K3 is less than K2.

[0083] B1, B2 and K1, K2, K3 are specific temperature values ​​and can be adjusted as needed. In general household air conditioners or central air conditioners, the first temperature B1 can be set to 15°C, the second temperature B2 can be set to 5°C, K1 can be set to 3°C, K2 can be set to 2°C, and K3 can be set to 1°C.

[0084] In a specific embodiment, Figure 3 As shown, the control method of the air-conditioning system of this embodiment first determines whether the fan gear is changed according to the target temperature and the current temperature of the indoor environment (indoor real-time temperature); if not, the air-conditioning is installed and continues to operate in the current state; if yes, first determine whether the indoor unit is in cooling mode or heating mode. In the heating case, the evaporation temperature, that is, the target temperature of the evaporator (indoor unit) is corrected by Tes2=Tes+δt to obtain the corrected target temperature, and then the system is operated according to the corrected new value, thereby achieving corresponding adjustment of the compressor operating frequency under different fan gears; in the heating case, the condensation temperature, that is, the target temperature of the condenser (indoor unit) is corrected by Tes1=Tes-δt to obtain the corrected target temperature, and then the system is operated according to the corrected new value, thereby achieving corresponding adjustment of the compressor operating frequency under different fan gears.

[0085] Through the control method of the air conditioning system of this embodiment, for example, when the air conditioning system is in the heating operation mode, assuming that the difference between the target temperature Tes and the indoor temperature (the current temperature T1 of the indoor environment) is large, the air conditioning system will automatically adjust and increase the fan gear, and according to the above-mentioned method of adaptively controlling the output according to the fan gear, the target condensing temperature will be automatically corrected, and the correction method is that the new target Tes2 after correction is equal to the original Tes plus the temperature correction value δt. Since the change of the fan gear is to increase the fan gear, the value of δt calculated according to the two key parameters of the target temperature adjustment coefficient and the fan gear is a positive value. In this way, the new target Tes2 obtained by adding the temperature correction value δt to the original Tes is greater than the original Tes. In order to achieve the corrected Tes2, the outdoor unit of the air conditioning system needs to increase the operating frequency of the compressor, and the heating output of the synchronous air conditioning system increases, which can quickly increase the indoor temperature and reduce the difference between the target temperature Tes and the indoor temperature, so as to meet the user's use needs in a timely manner and improve the user's use comfort.

[0086] On the contrary, when the difference between the target temperature Tes and the indoor temperature T1 is small and the fan gear of the indoor unit of the air conditioner is automatically reduced, the calculated correction value δt is a negative value, that is, the corrected Tcs is smaller than the original Tcs, the operating frequency of the compressor will be reduced, and the heating output of the synchronous air conditioner will be reduced to reduce the operating energy consumption of the air-conditioning system and avoid frequent temperature shutdowns.

[0087] The control method of the air-conditioning system in this embodiment solves the problem that the air conditioner in some technologies automatically changes the fan gear control output according to energy demand, but the outdoor unit has no corresponding action and the temperature control speed is slow. According to the fan gear adaptive control output mode of the indoor unit, when the indoor unit automatically changes the fan gear according to the indoor ambient temperature, the air-conditioning system automatically changes the fan gear and then synchronously adjusts the operating frequency of the compressor to achieve rapid adjustment of the indoor temperature. It can be used in conventional air-conditioning and heat pump systems.
