[0059] Background

[0060] In modern life, the accelerated urbanization process has led to serious air pollution, especially during the winter heating period, when many families close their windows, resulting in poor indoor air circulation, increased CO2 concentration, and decreased O2 concentration, which affects human health. Modern people pay more and more attention to the quality of life and health, and their requirements for living environment have also changed from basic safety and comfort to a healthier one. Oxygen-generating air conditioners can provide air conditions that are closer to the natural environment, meeting people's pursuit of high-quality life.

[0061] In oxygen-generating air conditioning technology, in order to improve indoor air quality, the air conditioner increases the oxygen content of indoor air by setting up an oxygen-generating module. The oxygen-generating module usually uses a combination of an air compressor, a molecular sieve, and a filter to produce oxygen. The temperature of the gas coming out of the air compressor is generally high and needs to be cooled before it can pass through the molecular sieve. However, adding additional cooling equipment will make the oxygen-generating module complex, bulky, and take up space.

[0062] Based on this, Figure 1-Figure 4 As shown, the first aspect of the embodiment of the present application provides an air conditioner, characterized in that it includes:

[0063] The evaporator 100 and the condenser 200 are connected to each other via a refrigerant pipeline 300;

[0064] An oxygen production component, the oxygen production component includes an air compressor module 400 and a molecular sieve module 500, and a gas pipeline 600 is provided between the air compressor module 400 and the molecular sieve module 500, and the gas pipeline 600 is used to transmit the air compressed by the air compressor module 400 to the molecular sieve module 500, and decompose the air into oxygen and other gases including nitrogen through the molecular sieve module 500;

[0065] The gas delivery pipeline 600 includes a first gas delivery pipeline 601 and a second gas delivery pipeline 602. At least a portion of the first gas delivery pipeline 601 on its gas delivery path is thermally coupled to the evaporator 100, and at least a portion of the second gas delivery pipeline 602 on its gas delivery path is thermally coupled to the condenser 200.

[0066] The air conditioner has a cooling mode and a heating mode. When the air conditioner operates in the cooling mode, the air conditioner controls the air compressor module 400 and the molecular sieve module 500 to be connected through the first gas pipeline 601, so as to use the low-temperature evaporator 100 to cool down the high-temperature air in the first gas pipeline 601. When the air conditioner operates in the heating mode, the air conditioner controls the air compressor module 400 and the molecular sieve module 500 to be connected through the second gas pipeline 602, so as to use the low-temperature condenser 200 to cool down the high-temperature air in the second gas pipeline 602.

[0067] In the embodiment of the present application, the gas pipeline 600 is thermally coupled with the evaporator 100 and the condenser 200, and the high-temperature air compressed by the air compressor module 400 is cooled by using the air conditioner's own cooling and heating cycles. This method can reduce the consumption of additional energy and improve overall energy efficiency. At the same time, since molecular sieves work more efficiently at appropriate temperatures, this design helps to improve oxygen production efficiency. The air conditioner can automatically adjust the use of the gas pipeline according to the cooling mode and the heating mode. This design enables the system to be flexibly adjusted according to the current operating mode to achieve the best cooling effect.

[0068] Furthermore, in some possible implementations, the evaporator 100 is provided with a plurality of evaporator tube holes, a portion of the plurality of evaporator tube holes is penetrated with the refrigerant pipeline 300, and another portion is penetrated with the first gas pipeline 601;

[0069] The condenser 200 is provided with a plurality of condenser tube holes, a portion of which is penetrated by the refrigerant pipeline 300 , and another portion of which is penetrated by the second gas pipeline 602 .

[0070] In the embodiment of the present application, by providing a plurality of tube holes on the evaporator 100 and the condenser 200, and passing the refrigerant pipeline 300 and the gas pipeline 600 through these tube holes respectively, the space of the evaporator 100 and the condenser 200 can be more effectively utilized, and the overall structural layout can be optimized. This design helps to reduce additional pipeline connections and simplify installation and maintenance work. By passing the first gas pipeline 601 and the second gas pipeline 602 directly through the tube holes of the evaporator 100 and the condenser 200, the cooling capacity of the evaporator 100 and the condenser 200 can be maximized. This direct contact method helps to reduce the temperature of the high-temperature air in the gas pipeline 600 more quickly, thereby improving the heat exchange efficiency.

[0071] Further, in some possible implementations, the first gas pipeline 601 includes a first gas pipeline section located in the evaporator tube hole. When the first gas pipeline 601 passes through a plurality of evaporator tube holes, a refrigerant pipeline 300 passing through the evaporator tube hole is provided between two adjacent first gas pipeline sections;

[0072] and / or

[0073] The second gas pipeline 602 includes a second gas pipeline section disposed in the condenser tube hole. When the second gas pipeline 602 passes through a plurality of evaporator tube holes, a refrigerant pipeline 300 passing through the condenser tube hole is disposed between two adjacent second gas pipeline sections.

[0074] In the embodiment of the present application, by alternately arranging the gas delivery pipe section and the refrigerant pipeline in the tube holes of the evaporator 100 and the condenser 200, the cooling effect of the refrigerant can be maximized to reduce the air temperature in the gas delivery pipeline. This alternating layout enhances the efficiency of heat exchange, because the refrigerant pipeline is directly adjacent to the gas delivery pipe section, making heat transfer more direct and efficient. Through more efficient heat exchange, the energy required to reach the desired temperature can be reduced, thereby reducing the energy consumption of the entire air conditioner.

[0075] Furthermore, in some possible embodiments, the air conditioner also includes a gas pipeline reversing valve 700, and by controlling the reversing of the gas pipeline reversing valve 700, the air compressor module 400 and the molecular sieve module 500 can be connected through the first gas pipeline 601 or through the second gas pipeline 602.

[0076] In the embodiment of the present application, the air supply pipeline reversing valve 700 can be used to flexibly switch the connection between the air compressor module 400 and the molecular sieve module 500 according to the needs of the cooling mode and the heating mode, thereby realizing the connection through the first gas supply pipeline 601 or the second gas supply pipeline 602, thereby improving the adaptability and flexibility of the system. The gas supply pipeline reversing valve 700 allows the system to accurately control the flow direction of high-temperature compressed air according to the current working mode {cooling or heating}, ensuring that the air reaches the optimal temperature before entering the molecular sieve module, thereby improving the oxygen production efficiency and the service life of the molecular sieve. By controlling the reversing valve, the system can more effectively utilize the cooling capacity of the evaporator and condenser, reduce energy waste, and improve the energy efficiency of the entire air conditioner. Using a reversing valve to control the connectivity of the gas supply pipeline can reduce the number and complexity of pipelines required, simplify system design, and reduce manufacturing costs and maintenance difficulties.

[0077] Further, in some possible implementations, the gas pipeline reversing valve 700 includes a first reversing valve 701 and a second reversing valve 702;

[0078] The gas transmission pipeline 600 includes a first main pipe section 600a connected between the exhaust port of the air compressor module and the air inlet of the first reversing valve, a second main pipe section 600b connected between the exhaust port of the second reversing valve and the air inlet of the molecular sieve, and a first branch pipe section 600c and a second branch pipe section 600d connected in parallel between the first reversing valve 701 and the second reversing valve 702;

[0079] When the first reversing valve 701 and the second reversing valve 702 are controlled to switch directions in the first situation, the first main pipe section 600a, the first branch pipe section 600c and the second main pipe section 600b are connected in sequence to form a first gas pipeline 601. When the first reversing valve 701 and the second reversing valve 702 are controlled to switch directions in the second situation, the first main pipe section 600a, the second branch pipe section 600d and the second main pipe section 600b are connected in sequence to form a second gas pipeline 602.

[0080] In the embodiment of the present application, the precise control of the first reversing valve 701 and the second reversing valve 702 can achieve precise guidance of the air flow between the air compressor module 400 and the molecular sieve module 500. This precise control helps to ensure that the compressed air enters the molecular sieve module at the correct temperature and improves the oxygen production efficiency. By configuring the two reversing valves and the main pipe section and the branch pipe section, the system can flexibly switch the first gas pipeline 601 and the second gas pipeline 602 as needed to adapt to different working modes and environmental conditions.

[0081] Further, in some possible embodiments, the molecular sieve module 500 has an oxygen outlet for discharging oxygen and other gas outlets for discharging other gases, and the other gas outlets are connected to an outdoor exhaust pipe 800 for discharging other gases including nitrogen to the outdoors;

[0082] The outdoor exhaust pipe 800 is also connected to an auxiliary air inlet 801, wherein the air inlet end of the auxiliary air inlet 801 is arranged close to the air compressor module 400. When the outdoor exhaust pipe 800 discharges gas to the outdoors, negative pressure can be generated at the auxiliary air inlet 801, and the airflow at the air compressor module 400 can be sucked into the outdoor exhaust pipe 800 under the action of the negative pressure.

[0083] In the embodiment of the present application, unnecessary gas is discharged outdoors through the outdoor exhaust pipe 800, and the airflow at the air compressor module 400 is sucked by the negative pressure generated by the auxiliary air inlet 801, so that the air compressor module 400 can be cooled. It is worth noting that a closed space for installing the air compressor module 400 is provided in the oxygen production component, and the space is connected to the outdoor fresh air. Specifically, the fluidity of the high-pressure nitrogen in the outdoor exhaust pipe 800 is used to drive the air at normal temperature and low pressure into the closed space where the air compressor module 400 is installed, and the air compressor temperature is taken away through the surface of the air compressor, and the air compressor module is cooled, and then discharged from the outdoor unit together with the nitrogen, which can effectively reduce the operating temperature of the air compressor module and improve its working efficiency and life.

[0084] Furthermore, in some possible implementations, the molecular sieve module includes a plurality of molecular sieve oxygen generators 501 and a plurality of molecular sieve reversing valves 502 , and the plurality of molecular sieve oxygen generators 501 can be operated simultaneously or alternately by controlling the reversing of the molecular sieve reversing valves 502 .

[0085] In the embodiment of the present application, by operating multiple molecular sieve oxygen generators 501 in parallel or alternately, the oxygen production efficiency can be significantly improved to meet a greater oxygen demand or provide the same amount of oxygen in a shorter time. When it is necessary to quickly increase the oxygen production, multiple molecular sieve oxygen generators can be started at the same time to quickly respond to changes in oxygen demand. The configuration of multiple molecular sieve oxygen generators provides redundancy. Even if one of the devices fails, the other devices can continue to work, thereby improving the reliability and stability of the system. By alternating the operation of multiple molecular sieve oxygen generators, the frequency of use of a single device can be reduced, thereby extending the service life of the molecular sieve and reducing maintenance costs. By controlling the reversing of the molecular sieve reversing valve 502, the operating mode of the oxygen generator can be flexibly adjusted to adapt to different oxygen production needs and working conditions.

[0086] Further, in some possible implementations, the air conditioner includes an indoor unit 10 equipped with an evaporator 100 and an outdoor unit 20 equipped with a condenser 200;

[0087] An air outlet duct 30 communicating with an air outlet of the indoor unit is formed in the indoor unit 10 , wherein the oxygen outlet of the molecular sieve module 500 is communicated with the air outlet duct 30 .

[0088] In the embodiment of the present application, the oxygen outlet of the molecular sieve module 500 is directly connected to the air outlet 30 of the indoor unit 10. Such a design can reduce the resistance and energy loss during the oxygen delivery process and improve the oxygen delivery efficiency. By connecting the oxygen outlet to the air outlet 30, the air outlet system of the air conditioner can be used to evenly distribute oxygen to the indoor space, thereby improving the indoor air quality.

[0089] Furthermore, in some possible implementations, the oxygen production component also includes:

[0090] An oxygen generator housing 900 is disposed on the top of the outdoor unit 20, and an air compressor module 400 and a molecular sieve module 500 are integrated inside the oxygen generator housing 900;

[0091] A fresh air inlet 901 connected to the outdoor environment is also provided on the oxygen-generating housing 900 disposed on the top of the outdoor unit 20 . The fresh air inlet 901 is connected to the air compressor module 400 , and a filter 902 is provided at the fresh air inlet 901 .

[0092] In the embodiment of the present application, by setting the oxygen production shell 900 at the top of the outdoor unit 20 and integrating the air compressor module 400 and the molecular sieve module 500 therein, the compact integration of the air conditioner and the oxygen production function is achieved, which saves space and improves the overall aesthetics. By setting the fresh air inlet 901 at the top of the outdoor unit, fresh air can be directly introduced from the outdoor environment. This design helps to improve the air intake efficiency of the air compressor module and reduce the resistance of air flow. A filter 902 is provided at the fresh air inlet 901, which can filter out impurities and dust in the outdoor air to ensure that the air entering the air compressor module is clean, thereby improving the oxygen production efficiency and the service life of the molecular sieve. Integrating the oxygen production component in the oxygen production shell at the top of the outdoor unit helps to protect the internal components from the influence of bad weather and improve the stability and durability of the system. The oxygen production shell 900 can play a certain role in isolating the operating noise and vibration of the air compressor module 400 and the molecular sieve module 500, reducing the impact on the surrounding environment. Since the fresh air inlet is directly connected to the outdoor environment, the energy loss during air transportation is reduced, and the energy efficiency of the system is improved. The integrated oxygen generator assembly simplifies the installation process. At the same time, since all oxygen generator related components are concentrated in one location, maintenance and inspection work becomes more convenient. The setting of the oxygen generator housing 900 helps to prevent the leakage of high-pressure gas inside the outdoor unit, and the filter element 902 can prevent possible foreign matter from entering the air compressor module, thereby improving the safety of the system.

[0093] Further, in some possible implementations, the air conditioner is a window air conditioner, and the window air conditioner further includes an indoor fan 40 disposed in the indoor unit 10, and an outdoor fan 50 disposed in the outdoor unit 20;

[0094] The indoor fan 40 and the outdoor fan 50 are driven by a fan motor 60, and the fan motor 60 can drive the indoor fan 40 and the outdoor fan 50 to rotate simultaneously or the fan motor 60 can drive one of the indoor fan 40 and the outdoor fan 50 to rotate separately.

[0095] In the design of the window air conditioner of the embodiment of the present application, the indoor fan 40 and the outdoor fan 50 share a fan motor 60. This design can reduce the number of components, save space, and reduce manufacturing costs. The fan motor 60 can drive two fans at the same time, or drive one of them alone. This flexibility allows the system to adjust the working state of the fan according to actual needs and improve the accuracy of control.

[0096] Furthermore, in some possible implementations, the indoor fan 40 is a centrifugal fan whose air inlet corresponds to the evaporator 100 and whose air outlet is connected to the air outlet duct 30 , and the outdoor fan 50 is an axial flow fan whose air outlet corresponds to the condenser 200 .

[0097] In order to more clearly understand the structure and working principle of the air conditioner in the embodiment of the present application, Figure 1-Figure 4 To explain in detail:

[0098] like Figure 1-Figure 4 As shown, the air conditioner in the embodiment of the present application is an integrated air conditioner {ie, a window air conditioner}.

[0099] The air compressor module 400 is a key component in the air conditioning system, responsible for providing pressure to the air and delivering it to the molecular sieve module 500. However, the air compressor module 400 generates a lot of noise during operation. Based on this, in the embodiment of the present application, the air compressor is designed above the side of the integrated air conditioner external unit to form a separate space, and sound insulation materials are added to the four walls of the space to reduce the impact of the air compressor noise on the room.

[0100] Molecular sieve is a highly efficient gas separation material that can separate oxygen and nitrogen in the air. The separated oxygen is discharged into the indoor unit along with the cooling or heating air of the indoor machine, improving the indoor air quality and providing a fresher and healthier air environment.

[0101] The temperature of the air compressed by the air compressor can reach 80℃~100℃, but the molecular sieve oxygen production temperature should be between 5℃~55℃. Usually, at room temperature {20℃-30℃}, the molecular sieve has a strong adsorption capacity for nitrogen and can effectively separate nitrogen from the air. Too low temperature will affect the adsorption efficiency of the molecular sieve, and too high temperature may cause structural damage to the molecular sieve. Therefore, it is necessary to cool down the temperature coming out of the air compressor. Specifically, in the embodiment of the present application, two rows of U-shaped pipes {i.e., the second gas pipeline 602 and the second gas pipeline 601} are designed in the condenser 200 of the outdoor unit 200 and the evaporator 100 of the indoor unit 100 respectively to connect the air compressor module 400. Under the refrigeration condition, the low temperature of the evaporator 100 of the indoor unit 10 is used to cool down the high temperature air coming out of the air compressor, and under the heating condition, the low temperature of the condenser 200 of the outdoor unit 20 is used to cool down the high temperature air coming out of the air compressor. Then it enters the molecular sieve module 500, which can greatly improve the life of the molecular sieve and the oxygen production efficiency.

[0102] The high-pressure nitrogen after desorption of the molecular sieve is released to the outdoors through the outdoor exhaust pipe 800. The flow of high-pressure nitrogen drives the low-pressure air at room temperature into the enclosed space where the air compressor module 400 is installed. The air compressor temperature is taken away by the surface of the air compressor, and the air compressor is cooled. The air compressor is then discharged from the outdoor unit together with the nitrogen, which can effectively reduce the operating temperature of the air compressor and improve its working efficiency and life.

[0103] like Figure 2As shown, under refrigeration conditions, the molecular sieve oxygen production process is: outdoor air is filtered through the filter element 902 and then enters the air compressor module 400, the air compressor module 400 generates high-temperature and high-pressure air, the high-temperature and high-pressure air passes through the first main pipe section 600a and the first reversing valve 701 and then enters the evaporator 100 of the indoor unit 10 through the first half of the first branch pipe section 600c for cooling, the high-temperature and high-pressure gas becomes low-temperature and high-pressure gas and then enters the second main pipe section 600b through the second half of the first branch pipe 600c and the second reversing valve 702, and enters the molecular sieve module 500 through the second main pipe section 600b, the oxygen enters the pipeline after passing through the molecular sieve module 500 and enters the indoor unit 10 after passing through the molecular sieve reversing valve 502 and the throttle valve, and enters the room together with the air circulating in the indoor unit, and the nitrogen is adsorbed on the molecular sieve.

[0104] like Figure 3 As shown, under the heating condition, the molecular sieve oxygen production process is: the outdoor air is filtered through the filter element 902 and then enters the air compressor module 400, the air compressor module 400 generates high-temperature and high-pressure air, the high-temperature and high-pressure air passes through the first main pipe section 600a and the first reversing valve 701 and then enters the condenser 200 of the outdoor unit 20 through the first half of the second branch pipe section 600d for cooling, the high-temperature and high-pressure gas becomes low-temperature and high-pressure gas and then enters the second main pipe section 600b through the second half of the second branch pipe section 600d and the second reversing valve 702, and enters the molecular sieve module 500 through the second main pipe section 600b, the oxygen enters the pipeline after passing through the molecular sieve module 500 and enters the indoor unit 10 after passing through the molecular sieve reversing valve 502 and the throttle valve, and enters the room together with the air circulated in the indoor unit, and the nitrogen is adsorbed on the molecular sieve.

[0105] like Figure 1-Figure 4 As shown, the molecular sieve module 500 is designed with two identical molecular sieves, which can alternately produce oxygen and desorb, work reciprocatingly, and continuously produce oxygen. The switching between the two molecular sieves is achieved through three molecular sieve reversing valves 502.

[0106] An oxygen concentration sensor is designed at the air inlet of the indoor unit to monitor the indoor oxygen concentration. The start and stop of the oxygen generator is controlled according to the oxygen concentration, and the amount of oxygen discharged into the room is controlled by a throttle valve.

[0107] After the molecular sieve is saturated with nitrogen, the molecular sieve is heated to desorb nitrogen, and the discharged high-temperature and high-pressure nitrogen is discharged from the outdoor unit through the outdoor exhaust pipe 800. Figure 1-Figure 4As shown, the "human" shaped pipeline design is designed in the middle of the pipeline, which can use the high-pressure flow of nitrogen to attract air into the air compressor installation cavity to absorb the surface temperature of the air compressor and then enter the pipeline and be discharged together with the nitrogen. On the one hand, it can effectively reduce the operating temperature of the air compressor and improve its working efficiency and life. On the other hand, it can reduce the discharge temperature of nitrogen to prevent disturbing the ambient air temperature of the outdoor unit.
