[0044] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Reference Figure 1, shows a flow chart of a control method for an energy-saving device provided by an embodiment of the present invention, wherein the energy-saving device is arranged in an air-conditioning system, and the energy-saving device is electrically connected to a compressor and a damper of the air-conditioning system respectively, and the control method may specifically include the following steps:

[0046] Step 101, obtaining the operating state parameters of the air conditioning system, and determining a target operating mode according to the operating state parameters; wherein the target operating mode includes an energy-saving mode and a non-energy-saving mode;

[0047] The compressor is mainly responsible for compressing and transporting the refrigerant in the air-conditioning system, making it circulate in the system to achieve cooling or heating functions.

[0048] The air valve is a valve component used to control air flow in the air conditioning system. By controlling the opening of the air valve, the amount of fresh air entering the room can be controlled. Fresh air refers to the fresh air introduced from the outside into the room by the air conditioning system, which is used to replenish oxygen in the indoor air, remove carbon dioxide and other pollutants, and improve the indoor air quality.

[0049] The operating status parameters of the air conditioning system are key parameters that describe the current operating status of the air conditioning system. These parameters affect the operating efficiency, energy consumption and comfort of the indoor environment of the system. Specifically, the operating status parameters may include temperature parameters such as the fresh air temperature value and the outlet air temperature value in the air conditioning system, air volume parameters such as the outlet air volume and the return air volume, or energy consumption parameters such as the compressor energy consumption and the fan energy consumption.

[0050] The energy-saving mode is an operating mode in which the air-conditioning system instructs the energy-saving device to perform energy-saving control on each component; in contrast, the non-energy-saving mode is a normal operating mode in which no energy-saving control is performed, and the air-conditioning system operates in the non-energy-saving mode by default.

[0051] In this embodiment, the operating status parameters of the air-conditioning system are obtained to determine whether it is necessary to enter the energy-saving mode or the non-energy-saving mode, so that the energy-saving device can control the air-conditioning system accordingly.

[0052] In some embodiments of the present invention, the operating status parameters include one or more of the following: fresh air temperature value, outlet air temperature value, fresh air enthalpy value, and enthalpy difference between fresh air and return air.

[0053] The fresh air temperature value is the detected temperature value corresponding to the fresh air. The enthalpy value is a physical quantity that describes the heat content of a substance. The fresh air enthalpy value is the value that characterizes the heat content of the fresh air.

[0054] The air outlet of the air conditioning system refers to the air sent into the room after being processed by the air conditioning system, and the air outlet temperature value refers to the detected temperature value corresponding to the air outlet of the air conditioning system.

[0055] The return air of the air conditioning system refers to the air that returns from the room to the air conditioning system, usually the air collected through the return air vents. The enthalpy difference between the fresh air and the return air is the difference between the fresh air enthalpy value and the return air enthalpy value.

[0056] In this embodiment, by obtaining air-related temperature or heat parameters such as fresh air temperature value, outlet air temperature value, fresh air enthalpy value, enthalpy difference between fresh air and return air, the energy utilization efficiency of the system and whether the temperature or heat conditions of the indoor environment meet the requirements can be evaluated, and then the target operating mode can be determined to perform corresponding energy-saving control.

[0057] In some embodiments of the present invention, determining the target operating mode according to the operating state parameter includes:

[0058] If the fresh air temperature value is less than the first threshold value, and / or the outlet air temperature value is less than the second threshold value, and / or the fresh air enthalpy value is less than the third threshold value, and / or the enthalpy difference between the fresh air and the return air is greater than the fourth threshold value, then the target operation mode is determined to be the energy-saving mode;

[0059] If the fresh air temperature value is greater than or equal to the first threshold, and / or the outlet air temperature value is greater than or equal to the second threshold, and / or the fresh air enthalpy value is greater than or equal to the third threshold, and / or the enthalpy difference between the fresh air and the return air is less than or equal to the fourth threshold, then the target operating mode is determined to be the non-energy-saving mode.

[0060] In this embodiment, the first threshold, the second threshold, the third threshold, and the fourth threshold are all thresholds corresponding to various operating state parameters for judging whether to enter the energy-saving mode, and can be set according to the actual needs, such as the setting of the fresh air function in combination with the cooling mode of the air-conditioning system and the indoor air quality requirements. Specifically, when the fresh air temperature value is less than the first threshold and / or the outlet air temperature value is less than the second threshold, it means that the air-conditioning system has met the cooling demand of the current environment, and it is necessary to enter the energy-saving mode to instruct the energy-saving device to perform energy-saving control; when the fresh air enthalpy value is greater than or equal to the third threshold and / or the enthalpy difference between the fresh air and the return air is less than or equal to the fourth threshold, it means that the fresh air introduced into the room by the air-conditioning system has met the air quality requirements of the current environment, and it is necessary to enter the energy-saving mode to instruct the energy-saving device to perform energy-saving control. Therefore, when one or more of the judgment conditions such as the fresh air temperature value is greater than or equal to the first threshold, the outlet air temperature value is greater than or equal to the second threshold, the fresh air enthalpy value is greater than or equal to the third threshold, and the enthalpy difference between the fresh air and the return air is less than or equal to the fourth threshold are met, the target operation mode is determined to be the energy-saving mode, otherwise the non-energy-saving mode is maintained.

[0061] In practical applications, the first threshold, the second threshold, the third threshold, and the fourth threshold (collectively referred to as thresholds) can be set within a certain numerical range, and when certain conditions are met, the target operation mode is determined to be the energy-saving mode, as shown in Table 1:

[0062] Table 1

[0063]

[0064] Step 102, detecting whether there is human activity within a preset range and obtaining a detection result;

[0065] The preset range can be the entire range of the indoor area covered by the air-conditioning system, or a part of the range, such as the kitchen, bedroom, bathroom, etc. divided by function.

[0066] The detection results include two types: there are people active in the preset range and there are no people active in the preset range.

[0067] In this embodiment, the detection result of whether there is human activity within the preset range can be used as one of the important reference conditions for the energy-saving device to perform energy-saving control. For example, if there is no human activity within the preset range, energy-saving control can be performed as much as possible, and if there is human activity within the preset range, energy-saving control needs to be performed while taking into account the user's comfort.

[0068] Step 103: Control the capacity gear of the compressor and / or the opening of the air valve according to the target operation mode and the detection result.

[0069] The capacity gear of the compressor refers to the division of the cooling or heating capacity of the compressor into different gears. The higher the gear, the higher the cooling or heating capacity and the higher the energy consumption. As an example, it can be divided according to the output power of the compressor or the speed of the compressor. When the compressor runs at half of the maximum output power or half of the maximum speed, the corresponding capacity gear is the first gear (50%). When the compressor runs at the maximum output power or the maximum speed, the corresponding capacity gear is the second gear (100%).

[0070] In this embodiment, by determining whether the target operating mode is an energy-saving mode or a non-energy-saving mode, and detecting whether there is human activity within a preset range, the capacity gear of the compressor and / or the opening of the air valve are controlled. For example, the corresponding capacity gear is opened or closed to control the energy consumption of the compressor, and the opening of the air valve is increased or decreased to control the air volume of fresh air circulating indoors. Ultimately, energy-saving control that takes into account both user comfort and energy efficiency of the air-conditioning system is achieved, achieving comfortable, energy-saving and healthy effects.

[0071] In some embodiments of the present invention, the compressor is provided with at least a first capacity gear and a second capacity gear, the second capacity gear is greater than the first capacity gear; the opening of the air valve is set to not allow manual control; when the air valve is in the closed state, the opening of the air valve is 0; when the air valve is in the open state, the opening range of the air valve is between a first preset opening and a second preset opening.

[0072] In this embodiment, the compressor is provided with at least two capacity gears, namely, a first capacity gear and a second capacity gear, and the second capacity gear is greater than the first capacity gear, that is, the energy consumption of the compressor when the second capacity gear is turned on is higher than when the first capacity gear is turned on. In practical applications, more capacity gears can be divided according to the cooling or heating capacity of the compressor, for example, based on 100% cooling or heating capacity, it can be divided into four capacity gears of 25%, 50%, 75%, and 100% on average.

[0073] The opening of the air valve is automatically controlled by the air conditioning system by default, and manual control is not allowed. Manual control means that the user actively controls the air conditioning system through a remote control or a physical switch. When the air valve is closed, the opening of the air valve is 0. When the air valve is open, the opening of the air valve is set to a certain adjustable range, that is, the range between the first preset opening and the second preset opening. The first preset opening is the minimum opening, and the second preset opening is the maximum opening. As an example, the first preset opening can be 10%, and the second preset opening can be set to 100%, then the opening range of the air valve is 10%-100%. The larger the opening of the air valve, the greater the amount of fresh air introduced by the air conditioning system.

[0074] In some embodiments of the present invention, controlling the capacity gear of the compressor and / or the opening of the air valve according to the target operation mode and the detection result includes:

[0075] When the target operation mode is the energy-saving mode, and the detection result indicates that there is human activity in the preset range:

[0076] If the first capacity gear position and the second capacity gear position are both in the closed state, the opening of the air valve is controlled to be the first preset opening;

[0077] If the first capacity gear is in the on state and the second capacity gear is in the off state, the first capacity gear is closed and the opening of the air valve is set to allow manual control;

[0078] If the first capacity gear and the second capacity gear are both in the open state, the second capacity gear is closed, and the opening of the air valve is set to allow manual control.

[0079] In this embodiment, the original state of the first capacity gear is Y1-I, and the adjusted state is Y1-O. The original state of the second capacity gear is Y2-I, and the adjusted state is Y2-O. Whether there is human activity within the preset range is recorded as the detection result of OCC (Occupancy Control Circuit). OCC on represents that there is human activity within the preset range. The energy-saving control under the judgment conditions of energy-saving mode and human activity within the preset range can be specifically shown in Table 2:

[0080] Table 2

[0081]

[0082] Specifically, in energy-saving mode, if there are people moving around, energy-saving control needs to be performed while taking into account the user's environmental comfort. Therefore, when the first capacity gear and the second capacity gear are originally in the closed state, they remain closed and the air valve is adjusted to the first preset opening (minimum opening); when the first capacity gear is originally in the open state and the second capacity gear is originally in the closed state, the first capacity gear is closed to reduce the energy consumption of the compressor and allow the user to manually control the air valve opening according to the demand for indoor fresh air quality; when the first capacity gear is originally in the open state and the second capacity gear is originally in the open state, the first capacity gear is kept in the open state and the second capacity gear is closed to reduce the energy consumption of the compressor and allow manual control of the air valve opening.

[0083] In some embodiments of the present invention, controlling the capacity gear of the compressor and / or the opening of the air valve according to the target operation mode and the detection result further includes:

[0084] When the target operation mode is the energy-saving mode, and the detection result indicates that there is no human activity within the preset range:

[0085] If the first capacity gear position and the second capacity gear position are both in the closed state, closing the air valve;

[0086] If the first capacity gear is in the on state and the second capacity gear is in the off state, the first capacity gear is closed, and the opening of the air valve is controlled between 0 and the second preset opening;

[0087] If the first capacity gear and the second capacity gear are both in the open state, the second capacity gear is closed, and the opening of the air valve is controlled between 0 and the second preset opening.

[0088] In this embodiment, the original state of the first capacity gear is Y1-I, and the adjusted state is Y1-O. The original state of the second capacity gear is Y2-I, and the adjusted state is Y2-O. Whether there is human activity within the preset range is recorded as the detection result of OCC. OCC off represents that there is no human activity within the preset range. The energy-saving control under the judgment conditions of energy-saving mode and no human activity within the preset range can be specifically shown in Table 3:

[0089] Table 3

[0090]

[0091] Specifically, in energy-saving mode, if no one is active, energy-saving control can be performed as much as possible. Therefore, when the first capacity gear and the second capacity gear are originally in the closed state, they remain closed and the air valve is closed (the opening is 0); when the first capacity gear is originally in the open state and the second capacity gear is originally in the closed state, the first capacity gear is closed to reduce the energy consumption of the compressor, and the opening is controlled within the range of 0-the second preset opening (maximum opening), for example, according to the indoor air quality, the opening of the air valve is controlled in real time to adjust the amount of fresh air introduced into the room; when the first capacity gear is originally in the open state and the second capacity gear is originally in the open state, the first capacity gear is kept in the open state, and the second capacity gear is closed to reduce the energy consumption of the compressor, and the opening is controlled within the range of 0-the second preset opening.

[0092] In some embodiments of the present invention, controlling the capacity gear of the compressor and / or the opening of the air valve according to the target operation mode and the detection result further includes:

[0093] When the target operation mode is the non-energy-saving mode and the detection result indicates that there is human activity in the preset range, controlling the opening of the air valve to be the first preset opening;

[0094] When the target operation mode is the non-energy-saving mode and the detection result indicates that there is no human activity within the preset range, the air valve is closed.

[0095] In this embodiment, the original state of the first capacity gear is Y1-I, and the adjusted state is Y1-O, the original state of the second capacity gear is Y2-I, and the adjusted state is Y2-O, whether there is human activity within the preset range is recorded as the detection result of OCC, OCC on represents that there is human activity within the preset range, and OCC off represents that there is no human activity within the preset range, then the energy-saving control in the non-energy-saving mode can be specifically shown in Table 4:

[0096] Table 4

[0097]

[0098] Specifically, in the non-energy-saving mode, there is no need to control the capacity gear of the compressor to reduce its energy consumption. It is sufficient to only consider whether there is human activity to control the opening of the air valve. When there is human activity in the preset range, the opening of the air valve is controlled to be the first preset opening (minimum opening) to introduce outdoor fresh air to maintain a certain air quality; when there is no human activity in the preset range, the air valve can be directly closed to save energy consumption of the fresh air function.

[0099] In some embodiments of the present invention, after obtaining the operating state parameters of the air conditioning system and determining the target operating mode according to the operating state parameters, the method further includes:

[0100] Get the carbon dioxide concentration value;

[0101] The controlling the capacity gear of the compressor and / or the opening of the air valve according to the target operation mode and the detection result further includes:

[0102] The capacity gear of the compressor and / or the opening of the air valve are controlled according to the target operation mode, the detection result and the carbon dioxide concentration value.

[0103] The carbon dioxide concentration value, that is, the proportion of carbon dioxide in the air, can reflect the air quality. High concentrations of carbon dioxide will cause indoor air to be stale, affecting human health and comfort. If the concentration of carbon dioxide is too high, more fresh air needs to be introduced to improve air quality.

[0104] In this embodiment, the air-conditioning system may also be provided with a carbon dioxide sensor for detecting the carbon dioxide concentration of the indoor air, and controlling the capacity gear of the compressor and the opening of the air valve in combination with the target operating mode, the detection results of whether there are human activities within a preset range, and the carbon dioxide concentration value, so as to take into account the comfort of the indoor air environment while reducing the energy consumption of the air-conditioning system.

[0105] In the specific implementation, the corresponding energy-saving control can be performed in combination with whether the concentration value of carbon dioxide exceeds the set value. The original state of the first capacity gear is Y1-I, and the adjusted state is Y1-O. The original state of the second capacity gear is Y2-I, and the adjusted state is Y2-O. Whether there is human activity within the preset range is recorded as the OCC detection result. OCC off means that there is no human activity within the preset range. The energy-saving control combined with the carbon dioxide concentration value can be specifically shown in Table 5:

[0106] Table 5

[0107]

[0108] In some embodiments of the present invention, Figure 2As shown, a connection diagram of the energy-saving device and the components in the air-conditioning system is also provided, as follows:

[0109] In the air conditioning system, an energy-saving device (i.e., economizer) is added between the thermostat and the air conditioning unit. The thermostat is electrically connected to the mixed air temperature sensor, CO2 sensor, return air temperature sensor, and fresh air temperature sensor respectively to obtain corresponding operating status parameters.

[0110] The Y1 and Y2 control signals of the thermostat (Y1 represents the control signal of the first capacity gear, and Y2 represents the control signal of the second capacity gear) pass through the corresponding signal input terminals Y1I and Y2I of the economizer controller, and then are processed by the economizer controller according to the temperature and humidity conditions of the fresh air, return air and mixed air, and then confirmed and forwarded to the air-conditioning unit through the signal output terminals Y1O and Y2O.

[0111] The OCC (Occupancy Control Circuit) signal of the thermostat is transmitted through the line connecting the economizer and the air-conditioning unit at the same time. The OCC signal represents whether there is human activity within the preset range. According to the OCC signal and the temperature and humidity conditions of the fresh air, return air and mixed air, the control gears Y1O and Y2O are forwarded to the unit after processing and confirmation.

[0112] The O / B signal of the thermostat indicates the four-way valve signal sent by the thermostat to the unit, that is, running the cooling mode or heating mode, and synchronously forwarding the O / B signal to the economizer controller.

[0113] The W of the thermostat represents the control signal for turning on the heating mode, and G represents the control signal for turning on the indoor unit fan. The W and G signals are not transmitted through the line connected to the economizer controller, but are directly transmitted through the line connecting the thermostat and the air conditioning unit.

[0114] The embodiments of the present invention have the following advantages: by acquiring the operating status parameters of the air-conditioning system and determining the target operating mode according to the operating status parameters, wherein the target operating mode includes an energy-saving mode and a non-energy-saving mode, detecting whether there is human activity within a preset range, obtaining the detection result, and controlling the capacity gear of the compressor and / or the opening of the air valve according to the target operating mode and the detection result, intelligent energy-saving control that takes into account the comfort of the indoor environment is realized, and the energy efficiency of the air-conditioning system is effectively improved.
