[0002] Under the background that fresh air air conditioners are increasingly popular today, the traditional fresh air technology faces many challenges in the installation process. Usually, additional holes need to be punched or wall holes need to be enlarged during installation, or due to the small size of the air pipe, the fresh air volume is insufficient. In addition, the air pipe needs to be deliberately arranged in a circular shape and wrapped before it can be passed through the wall, which makes the installation process cumbersome and inconvenient. Especially in the case of large temperature difference between indoor and outdoor, in order to prevent the surface of the indoor fresh air pipe from producing condensation water due to low outdoor temperature, insulation cotton needs to be added to the air pipe, further increasing the complexity and cost of installation.

[0024] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0025] In order for those skilled in the art to better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] As introduced in the background, it is difficult to ensure that the fresh air inlet cross section is large and the probability of condensation in the fresh air duct is small in the prior art. To solve the above problems, the embodiments of the present application provide a fresh air conditioner, a control method of the fresh air conditioner and a fresh air conditioning system.

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0029] The embodiments of the present application provide a fresh air conditioner, as shown in the drawings, comprising: Figure 1

[0030] ​The duct 11 includes a wall-penetrating section duct 111 and an indoor section duct 112 connected together. The indoor section duct 112 is made of metal. The diameter of the wall-penetrating section duct 111 is not less than the diameter of the indoor section duct 112. The wall-penetrating section duct 111 is used to introduce fresh air from the outside into the room, and the indoor section duct 112 is used to transmit fresh air to the fresh air outlet (not shown) in the room.

[0031] A low-voltage generator 12 is electrically connected to one end of the indoor section duct 112. The low-voltage generator 12 is used to provide power to the indoor section duct 112 to generate heat.

[0032] Through the above embodiments, the fresh air air conditioner includes a duct and a low-voltage generator. The duct includes a wall-penetrating duct section and an indoor duct section. The indoor duct section is made of metal, and the diameter of the wall-penetrating duct section is not less than the diameter of the indoor duct section. The low-voltage generator is electrically connected to one end of the indoor duct section and provides power to heat it. Compared with the existing technology, which has difficulty in ensuring a large fresh air intake cross-section and a low probability of condensation in the fresh air duct, the duct of this application adopts a two-section design, divided into an indoor section and a wall-penetrating section. By designing the diameter of the wall-penetrating duct to be not less than the diameter of the indoor duct section, a large fresh air intake cross-section can be ensured, thereby increasing the fresh air volume and meeting the indoor air quality requirements. The indoor duct section is made of metal and is heated by the low-voltage generator, which can reduce the possibility of condensation on the surface of the indoor fresh air duct when there is a large temperature difference between indoors and outdoors. Condensation may lead to problems such as damp walls and mold growth, which can be effectively avoided by heating.

[0033] In addition, ordinary air ducts require additional insulation, which increases the wall thickness. With a fixed wall opening, the thicker the wall, the smaller the inner diameter and the smaller the air inlet cross-section, resulting in a greater impact on airflow. However, this application does not require additional insulation, thus ensuring a larger inner diameter and a larger fresh air inlet cross-section. Furthermore, due to the diameter design of the duct through the wall, the need for additional drilling or enlarging of the wall opening is reduced. It also avoids the cumbersome steps of deliberately shaping the duct into a circular shape and wrapping it before it can pass through the wall, simplifying the installation process.

[0034] Specifically, such as Figure 1 As shown, the wall-penetrating duct 111 represents the duct that passes through the wall 13.

[0035] In one alternative, such as Figure 2As shown, the indoor section air duct 112 includes an integrated first inner tube wall 1121, a first outer tube wall 1122, and a first skeleton 1123. The first skeleton 1123 is made of a metal material and is electrically connected to the weak current generator (not shown). In this embodiment, the indoor section air duct adopts an integrated first inner tube wall, a first outer tube wall, and a first skeleton structure, which can simplify the manufacturing and installation process of the air duct and improve the overall strength and stability.

[0036] According to some example embodiments of the present application, the wall-penetrating section air duct includes an integrated second inner tube wall, a second outer tube wall, and a second skeleton. In this embodiment, the wall-penetrating section air duct includes an integrated second inner tube wall, a second outer tube wall, and a second skeleton, which further simplifies the manufacturing and installation process of the air duct and further improves the overall strength and stability.

[0037] Specifically, the new air duct adopts a composite design, integrating the inner and outer walls of the air duct with the intermediate reinforcing skeleton to ensure structural stability and efficient ventilation. The new air duct adopts a two-section design, divided into an indoor section and a wall-penetrating section, where the diameter D1 of the wall-penetrating section air duct is not less than the diameter D2 of the indoor section air duct, i.e., D1 ≥ D2, ensuring that the cross-section of the wall-penetrating section air duct is as large as possible. This solves the problem of additional punching or reaming required for air conditioner installation due to the increase in the air inlet cross-section of the new air duct, allowing for an increase in the cross-sectional area of the new air duct without the need for additional punching or reaming.

[0038] In other embodiments, as shown in Figure 2 The first skeleton 1123 and the second skeleton (not shown) are both in a spiral shape. In this embodiment, the spiral structure can further increase the strength and stability of the air duct, making it more resistant to external pressure and bending force.

[0039] According to some example embodiments of the present application, as shown in Figure 1 and Figure 3 The new fresh air conditioner further includes a condenser pipe 14, a three-way adapter 15 including an inlet end 151, a first outlet end 152, and a second outlet end 153, the inlet end 151 being connected to the wall-penetrating section air duct 111, the first outlet end 152 being connected to the indoor section air duct 112, the condenser pipe 14 extending from the second outlet end 153, and part of the condenser pipe 14 being placed inside the wall-penetrating section air duct 111. The indoor unit 16 includes an evaporator (not shown) and a fresh air fan (not shown), one end of the condenser pipe 14 being connected to the evaporator, the weak current generator 12 being located on the indoor unit 16, and the indoor section air duct 112 being connected to the fresh air fan. In this embodiment, by integrating the condenser pipe, the three-way adapter, the indoor unit (evaporator), and the fresh air fan, the structure of the new fresh air conditioner is more compact and efficient, facilitating installation and maintenance.

[0040] Specifically, the refrigerant connecting pipe (i.e. condensing pipe), connecting line and drain pipe of the indoor and outdoor units of the air conditioner are bundled together to form a pipe bundle, which is placed inside the wall-penetrating section of the air duct and is taken out of the wall together, thus simplifying the installation and improving the aesthetic appearance; the skeleton of the indoor section of the air duct is made of metal material, one end of which is connected to the weak current generator to realize the heating of the metal skeleton; the pipe bundle composed of the refrigerant pipe, connecting line and drain pipe is separated from the indoor section of the air duct through a three-way adapter on the indoor side, and is installed separately. The problems of extra punching or hole expansion required for installation and the problem of condensation water easily generated on the surface of the fresh air duct due to a large temperature difference between the indoor and outdoor are solved, the problem of the indoor temperature being affected by the incoming fresh air due to too low outdoor temperature is solved; the skeleton of the fresh air duct is made of metal material to ensure the bending strength of the air duct and at the same time to eliminate the need for additional sponge insulation for the indoor section of the air duct, thus simplifying the structure of the fresh air duct, improving the reliability and reducing the cost.

[0041] Specifically, the skeleton (first skeleton) of the indoor section of the air duct is connected to the weak current generator, and then the air duct is connected to the fresh air unit, and the refrigerant pipe is connected to the evaporator of the indoor unit.

[0042] Specifically, the refrigerant pipe and connecting pipe are bundled together to form a pipe bundle when the air conditioner is installed, which is then placed into the wall-penetrating section of the air duct and is taken out of the wall together. The wall-penetrating section of the air duct is connected to the inlet end of the three-way adapter, the indoor section of the air duct is connected to the air duct connection port of the other end of the three-way adapter, the refrigerant pipe bundle is taken out of the other outlet end of the three-way adapter, and then the refrigerant pipe is sealed by being adhered around the outlet end with adhesive tape, thus completing the adapter on the indoor side.

[0043] In some optional embodiments of the present application, as shown in Figure 3 the diameter of the inlet end 151 is not less than the diameter of the first outlet end 152, the diameter of the first outlet end 152 is greater than the diameter of the second outlet end 153, and the length of the second outlet end 153 is greater than the length of the first outlet end 152. In this embodiment, the diameter of the inlet end is not less than the diameter of the first outlet end, which further ensures that the cross section of the fresh air inlet is large, and the length of the second outlet end is greater than the length of the first outlet end, which facilitates sealing.

[0044] Specifically, one end of the three-way adapter is designed with an inlet, and two outlets are designed side by side at the other end, as shown in Figure 3 the diameter d1 (i.e. the diameter of the inlet end 151) of the inlet and the diameters d2 (i.e. the diameter of the first outlet end 152) and d3 (i.e. the diameter of the second outlet end 153) of the two outlets at the other end satisfy d1≥d2>d3.

[0045] In some optional embodiments of the present application, as shown in Figure 3 the inlet end 151 and the first outlet end 152 are both provided with internal threads. In this embodiment, the inlet end and the first outlet end are both provided with internal threads, which facilitates the connection with the outer diameter of the air duct.

[0046] Specifically, the joints at both ends of the tee adapter that connect to the ductwork are designed with internal threads for easy connection to the outer diameter of the ductwork, and the refrigerant pipe outlet is designed to be longer than the indoor duct section for easy sealing.

[0047] The methods and embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Taking running on a mobile terminal as an example, Figure 4 This is a hardware structure block diagram of a mobile terminal for a control method of a fresh air conditioner according to an embodiment of the present invention. Figure 4 As shown, a mobile terminal may include one or more ( Figure 4 Only one is shown in the diagram. A processor 102 (which may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.) and a memory 104 for storing data are also shown. The mobile terminal may further include a transmission device 106 for communication functions and an input / output device 108. Those skilled in the art will understand that... Figure 4 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 4 The more or fewer components shown, or having the same Figure 4 The different configurations shown.

[0048] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the control method of the fresh air conditioner in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby implementing the above-described method. The memory 104 may include high-speed random access memory and non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the aforementioned networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof. The transmission device 106 is used to receive or send data via a network. Specific examples of the aforementioned networks may include wireless networks provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0049] A control method of a fresh air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided in the embodiment. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical sequence is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0050] Figure 5 A flowchart of a control method of a fresh air conditioner according to the embodiment of the application is shown in FIG. 1. As shown in FIG. 1, the method comprises the following steps: Figure 5

[0051] Step S201, obtaining an outdoor temperature;

[0052] Step S202, determining a difference between a preset temperature and the outdoor temperature as a first target difference;

[0053] Step S203, in the case that the first target difference is greater than 0, controlling the weak current generator to be turned on to power on the indoor section air pipe for heating;

[0054] Step S204, in the case that the first target difference is not greater than 0, controlling the weak current generator to be powered off.

[0055] According to the above embodiment, the outdoor temperature is first obtained, then the difference between the preset temperature and the outdoor temperature is determined as the first target difference, and finally in the case that the first target difference is greater than 0, the weak current generator is controlled to be turned on to power on the indoor section air pipe for heating, and in the case that the first target difference is not greater than 0, the weak current generator is controlled to be powered off. Compared with the problem that in the prior art, when the indoor and outdoor temperature difference is large, the outdoor low temperature leads to condensation water on the surface of the indoor fresh air pipe, the application can monitor the temperature difference between the indoor and outdoor by obtaining the outdoor temperature and calculating the difference (the first target difference) between the preset temperature and the outdoor temperature, in the case that the first target difference is greater than 0, the weak current generator is controlled to be turned on to power on the indoor section air pipe for heating, so that the fresh air pipe cannot generate condensation water, and in the case that the first target difference is not greater than 0, the weak current generator is controlled to be powered off to be in a shutdown state, thereby reducing the energy consumption of the air conditioner.

[0056] In an optional solution, after the weak current generator is controlled to be turned on, the method further comprises: determining a target running power according to the first target difference, and controlling the weak current generator to run according to the target running power. In the embodiment, by real-time monitoring and calculating the first target difference (i.e. the difference between the preset temperature and the outdoor temperature), the target running power required for the weak current generator to run can be determined, so that the heating of the indoor section air pipe can be more accurate and efficient, and the needs under different outdoor temperature conditions can be met.

[0057] ​Specifically, when the air conditioner is turned on, the sensor on the air conditioner starts collecting the temperature of the outdoor environment, and the program sets the following control variables: outdoor temperature p and program set temperature p1 (i.e. preset temperature), and the control variable is set as: p1-p. When p1-p>0, the weak current generator supplies power to the skeleton of the indoor section of the air pipe, and the greater the p1-p, the greater the power supplied, so that the skeleton generates heat to ensure that the fresh air pipe does not produce condensate water, and the fresh air in the pipe is preheated to reduce the impact of low outdoor temperature on indoor temperature. When p1-p<0, the weak current generator is powered off and in a shutdown state, reducing the energy consumption of the air conditioner.

[0058] In some optional solutions, the method further comprises: when the first target difference is greater than 0, obtaining the indoor air CO2 concentration value H; determining the second target difference as: H1-H / H1, wherein H1 is a preset air CO2 concentration value, and H is the second target difference; when 10%>H>0, controlling the fresh air machine to run at a first speed; when 50%>H>10%, controlling the fresh air machine to run at a second speed; and when H>50%, controlling the fresh air machine to run at a third speed, wherein the first speed is less than the second speed, and the second speed is less than the third speed. In this embodiment, by monitoring the CO2 concentration (H) in the indoor air and comparing it with the preset CO2 concentration value (H1), the second target difference (H) is calculated, so as to dynamically adjust the running speed of the fresh air machine. This method can effectively control the indoor air quality, maintain the appropriate CO2 concentration, and improve the comfort of the indoor environment.

[0059] Specifically, the program sets the following control variables: indoor air CO2 concentration value H and program set concentration H1 (i.e. preset air CO2 concentration value), and the control variable is set as: H1-H / H1, and the heating temperature of the skeleton of the fresh air pipe is W. When p1-p>0 and 10%>H>0, the fresh air machine runs at a low speed V1, and at this time the heating temperature of the skeleton of the fresh air pipe is W=p1+10% p; when p1-p>0 and 50%>H>10%, the fresh air machine runs at a medium speed V2, and at this time the heating temperature of the skeleton of the fresh air pipe is W=p1+50% p; when p1-p>0 and H>50%, the fresh air machine runs at a high speed V3, and at this time the heating temperature of the skeleton of the fresh air pipe is W=p1+p, so as to ensure that the incoming air can be effectively preheated and the impact on the indoor temperature is reduced.

[0060] Specifically, the system is designed with an intelligent temperature control function. By detecting the indoor and outdoor temperatures, when the indoor and outdoor temperature difference is large and the outdoor temperature is lower than the indoor temperature, the metal skeleton of the indoor section air pipe is automatically powered to generate heat. According to the different outdoor temperatures, the heating temperature of the air pipe skeleton is adjusted to ensure that the temperature of the air entering the indoor is equivalent to the indoor temperature, preventing the occurrence of condensation on the surface of the fresh air pipe and affecting the indoor temperature.

[0061] In order to enable those skilled in the art to more clearly understand the technical solutions of the present application, the implementation process of the control method of the fresh air conditioner will be described in detail below in combination with specific embodiments.

[0062] The present embodiment relates to a specific control method of a fresh air conditioner, as shown in Figure 3 The steps include:

[0063] Step S1: Obtain the outdoor temperature;

[0064] Step S2: Determine the difference between the preset temperature and the outdoor temperature as the first target difference;

[0065] Step S3: In the case where the first target difference is greater than 0, control the weak current generator to start to power and heat the indoor section air pipe, and according to the first target difference, determine the target operating power, and control the weak current generator to operate according to the target operating power;

[0066] Step S4: In the case where the first target difference is not greater than 0, control the weak current generator to be powered off.

[0067] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown.

[0068] The present application also provides a fresh air conditioning system, comprising: any of the above fresh air conditioners; a controller comprising: one or more processors, a memory, and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, and the one or more programs include a control method for executing any of the above fresh air conditioners.

[0069] In the above embodiment, the fresh air air conditioning system includes a fresh air conditioner and a control method thereof, wherein the fresh air conditioner includes a duct and a weak current generator, the duct includes a wall-penetrating section duct and an indoor section duct, the material of the indoor section duct includes a metal material, the diameter of the wall-penetrating section duct is not less than that of the indoor section duct, and the weak current generator is electrically connected to one end of the indoor section duct and used to provide power for the indoor section duct to heat it. Compared with the prior art which is difficult to ensure a large fresh air inlet cross section and a small probability of condensation in the fresh air duct, the duct of the present application is designed in two sections, i.e., an indoor section and a wall-penetrating section, and the diameter of the wall-penetrating section duct is designed to be not less than that of the indoor section duct, so as to ensure a large fresh air inlet cross section and thus improve the fresh air volume to meet the demand of indoor air quality. The indoor section duct is made of a metal material and heated by the weak current generator, which can reduce the possibility of condensation on the surface of the indoor fresh air duct when the temperature difference between indoor and outdoor is large. Condensation may cause wall dampness, mold growth and other problems, and heating can effectively avoid this phenomenon. In the control method of the fresh air conditioner, the outdoor temperature is first obtained, then the difference between the preset temperature and the outdoor temperature is determined as a first target difference, and finally when the first target difference is greater than 0, the weak current generator is controlled to be turned on to power and heat the indoor section duct, and when the first target difference is not greater than 0, the weak current generator is controlled to be powered off. Compared with the prior art in which outdoor low temperature causes condensation on the surface of the indoor fresh air duct when the temperature difference between indoor and outdoor is large, the present application can monitor the temperature difference between indoor and outdoor by obtaining the outdoor temperature and calculating the difference between the preset temperature and the outdoor temperature (the first target difference).
