[0059] BACKGROUND

[0060] In modern life, rapid urbanization has led to severe air pollution, especially during the winter heating season when many families close their windows, resulting in poor indoor air circulation, increased CO2 concentration, and decreased O2 concentration, all of which negatively impact human health. Modern people are increasingly focused on quality of life and health, and their requirements for living environments have shifted from basic safety and comfort to healthier options. Oxygen-generating air conditioners can provide air conditions closer to the natural environment, meeting people's pursuit of a high-quality life.

[0061] In oxygen-generating air conditioning technology, air conditioners improve indoor air quality by incorporating an oxygen-generating module to increase the oxygen content of the indoor air. This module typically uses an air compressor combined with molecular sieves and filters. The gas exiting the air compressor is generally quite hot and requires cooling before passing through the molecular sieve. However, adding additional cooling equipment would make the oxygen-generating module complex, bulky, and space-consuming.

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

[0063] Evaporator 100 and condenser 200 are connected by refrigerant pipe 300.

[0064] The oxygen generating component includes an air compressor module 400 and a molecular sieve module 500. An air supply pipeline 600 is provided between the air compressor module 400 and the molecular sieve module 500. The air supply pipeline 600 is used to transmit the air compressed by the air compressor module 400 to the molecular sieve module 500, and decompose it into oxygen and other gases containing nitrogen through the molecular sieve module 500.

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

[0066] The air conditioner has a cooling mode and a heating mode. When the air conditioner is running in cooling mode, the air compressor module 400 and the molecular sieve module 500 are connected through the first air supply pipeline 601 to cool the high-temperature air in the first air supply pipeline 601 using the low-temperature evaporator 100. When the air conditioner is running in heating mode, the air compressor module 400 and the molecular sieve module 500 are connected through the second air supply pipeline 602 to cool the high-temperature air in the second air supply pipeline 602 using the low-temperature condenser 200.

[0067] In the embodiments of the present application, the gas delivery 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 using the refrigeration and heating cycles of the air conditioner itself. This method can reduce the consumption of additional energy and improve overall energy efficiency. At the same time, since the molecular sieve works more efficiently at an appropriate temperature, this design helps to improve oxygen production efficiency. The air conditioner can automatically adjust the use of the gas delivery pipeline according to the refrigeration 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] Further, in some possible implementations, the evaporator 100 is provided with a plurality of evaporator tube holes, a part of the plurality of evaporator tube holes is provided with the refrigerant pipeline 300, and another part is provided with the first gas delivery pipeline 601.

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

[0070] In the embodiments 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 delivery pipeline 600 through these tube holes, 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 directly passing the first gas delivery pipeline 601 and the second gas delivery pipeline 602 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 more quickly reduce the temperature of the high-temperature air in the gas delivery pipeline 600, thereby improving heat exchange efficiency.

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

[0072] And / or

[0073] The second gas delivery pipeline 602 includes a second gas delivery pipeline segment located in the condenser tube hole. When the second gas delivery pipeline 602 passes through a plurality of evaporator tube holes, a refrigerant pipeline 300 passing through the condenser tube hole is arranged between adjacent two second gas delivery pipeline segments.

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

[0075] Further, in some possible embodiments, the air conditioner further comprises a gas conveying pipe line reversing valve 700, by controlling the reversing of the gas conveying pipe line reversing valve 700, the air compressor module 400 and the molecular sieve module 500 can be connected through the first gas conveying pipe line 601 or through the second gas conveying pipe line 602.

[0076] In the embodiments of the present application, through the gas conveying pipe line reversing valve 700, the air conditioner can flexibly switch the connection between the air compressor module 400 and the molecular sieve module 500 according to the needs of the refrigeration mode and the heating mode, thereby realizing the connection through the first gas conveying pipe line 601 or the second gas conveying pipe line 602, improving the adaptability and flexibility of the system. The gas conveying pipe line reversing valve 700 allows the system to accurately control the flow direction of high-temperature compressed air according to the current working mode (refrigeration 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 the condenser, reduce energy waste, and improve the energy efficiency of the entire air conditioner. By using the reversing valve to control the connectivity of the gas conveying pipe line, the number and complexity of the required pipelines can be reduced, the system design can be simplified, and the manufacturing cost and maintenance difficulty can be reduced.

[0077] Further, in some possible embodiments, the gas conveying pipe line reversing valve 700 comprises a first reversing valve 701 and a second reversing valve 702;

[0078] The gas conveying pipe line 600 comprises a first main pipe section 600a connected between the air compressor module exhaust port and the first reversing valve air inlet, a second main pipe section 600b connected between the second reversing valve exhaust port and the molecular sieve air inlet, 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] Wherein when the first reversing valve 701 and the second reversing valve 702 are controlled to reverse in the first situation, the first main pipe section 600a, the first branch pipe section 600c and the second main pipe section 600b are sequentially connected to form the first gas conveying pipe line 601, and when the first reversing valve 701 and the second reversing valve 702 are controlled to reverse in the second situation, the first main pipe section 600a, the second branch pipe section 600d and the second main pipe section 600b are sequentially connected to form the second gas conveying pipe line 602.

[0080] The precise control of the first reversing valve 701 and the second reversing valve 702 in the embodiments of the present application can realize the precise guidance of the airflow between the air compressor module 400 and the molecular sieve module 500. Such precise control helps to ensure that the compressed air enters the molecular sieve module at the correct temperature, thereby improving the oxygen production efficiency. By using two reversing valves and the configuration of the main pipe section and the branch pipe section, the system can flexibly switch the first gas conveying pipeline 601 and the second gas conveying 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 an other gas outlet for discharging other gas containing nitrogen, and the other gas outlet is connected with an outdoor exhaust pipe 800 for discharging the other gas containing nitrogen to the outdoor.

[0082] The outdoor exhaust pipe 800 is further connected with 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, and the auxiliary air inlet 801 can generate a negative pressure when the outdoor exhaust pipe 800 discharges gas to the outdoor, so that 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 embodiments of the present application, the outdoor exhaust pipe 800 is used to discharge the unnecessary gas to the outdoor, and the negative pressure generated by the auxiliary air inlet 801 is used to suck the airflow at the air compressor module 400, so that the air compressor module 400 can be cooled. It should be noted that the oxygen production assembly is provided with a sealed space for installing the air compressor module 400, and the space is connected with outdoor fresh air. Specifically, the flowability of the high-pressure nitrogen gas in the outdoor exhaust pipe 800 is used to drive the air at normal temperature and low pressure to enter the sealed space for installing the air compressor module 400, so that the air compressor module can be cooled by the air compressor surface, and then the nitrogen gas and the air are discharged to the outdoor machine, which can effectively reduce the operating temperature of the air compressor module and improve the working efficiency and service life of the air compressor module.

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

[0085] In the embodiments of the present application, the parallel or alternating operation of multiple molecular sieve oxygen production devices 501 can significantly improve the oxygen production efficiency, meet larger oxygen demand or provide the same amount of oxygen in a shorter time. When the oxygen production needs to be quickly increased, multiple molecular sieve oxygen production devices can be started simultaneously to quickly respond to changes in oxygen demand. The configuration of multiple molecular sieve oxygen production devices provides redundancy, so that even if one device fails, the other devices can still continue to work, thereby improving the reliability and stability of the system. By alternating the operation of multiple molecular sieve oxygen production devices, the frequency of use of a single device can be reduced, thereby prolonging the service life of the molecular sieve and reducing maintenance costs. By controlling the reversing of the molecular sieve reversing valve 502, the operation mode of the oxygen production device can be flexibly adjusted to adapt to different oxygen production demands and working conditions.

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

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

[0088] In the embodiments of the present application, the oxygen outlet of the molecular sieve module 500 is directly communicated to the air outlet duct 30 of the indoor unit 10, which can reduce the resistance and energy loss in the oxygen delivery process and improve the oxygen delivery efficiency. By communicating the oxygen outlet to the air outlet duct 30, the air outlet system of the air conditioner can be used to uniformly distribute oxygen to the indoor space, improving the indoor air quality.

[0089] Further, in some possible implementations, the oxygen production assembly further includes:

[0090] The oxygen production shell 900 is arranged on the top of the outdoor unit 20, and the air compressor module 400 and the molecular sieve module 500 are integrated inside the oxygen production shell 900.

[0091] The oxygen production shell 900 arranged on the top of the outdoor unit 20 is further provided with a fresh air inlet 901 communicating with the outdoor environment, the fresh air inlet 901 is communicated with the air compressor module 400, and the fresh air inlet 901 is provided with a filter 902.

[0092] In the embodiments of the present application, the oxygen production shell 900 is arranged on the top of the outdoor unit 20, and the air compressor module 400 and the molecular sieve module 500 are integrated therein, realizing compact integration of the air conditioner and the oxygen production function, saving space and improving overall aesthetics. By arranging the fresh air inlet 901 on 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 air flow resistance. The filter 902 is arranged at the fresh air inlet 901, which can filter out impurities and dust in the outdoor air, ensuring 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 assembly in the oxygen production shell on the top of the outdoor unit helps to protect the internal components from adverse weather conditions, improving the stability and durability of the system. The oxygen production shell 900 can isolate the running noise and vibration of the air compressor module 400 and the molecular sieve module 500 to some extent, reducing the impact on the surrounding environment. Since the fresh air inlet directly communicates with the outdoor environment, energy loss during air transportation is reduced, improving the energy efficiency of the system. The integrated oxygen production assembly simplifies the installation process, and since all oxygen production related components are concentrated in one location, maintenance and inspection work becomes more convenient. The arrangement of the oxygen production shell 900 helps to prevent leakage of high-pressure gas inside the outdoor unit, and the filter 902 can prevent foreign matter from entering the air compressor module, improving the safety of the system.

[0093] Further, in some possible embodiments, the air conditioner is a window type air conditioner, and the window type air conditioner further comprises an indoor fan 40 arranged in the indoor unit 10 and an outdoor fan 50 arranged 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.

[0095] In the design of the window type air conditioner in the embodiments of the present application, the indoor fan 40 and the outdoor fan 50 share one fan motor 60, which can reduce the number of components, save space, and reduce manufacturing costs. The fan motor 60 can drive both fans simultaneously or drive one of them individually, which flexibility allows the system to adjust the working state of the fan according to actual needs, improving the accuracy of control.

[0096] Further, in some possible embodiments, the indoor fan 40 is a centrifugal fan with an air inlet corresponding to the evaporator 100 and an air outlet communicating with the air outlet duct 30, and the outdoor fan 50 is an axial flow fan with an air outlet corresponding to the condenser 200.

[0097] In order to more clearly understand the structure and working principle of the air conditioner in the embodiments of the present application, the following will be specifically described in combination with the accompanying drawings. Figures 1-4

[0098] As shown in the drawings, the air conditioner in the embodiments of the present application is an integrated air conditioner (i.e. a window type air conditioner). Figures 1-4

[0099] The air compressor module 400 is a key component in the air conditioning system, responsible for providing pressure to the air for delivery into the molecular sieve module 500. However, the air compressor module 400 generates a large noise during operation. Based on this, in the embodiments of the present application, the air compressor is designed on the upper side of the integrated air conditioner outdoor unit, forming a separate space, and sound insulation materials are added to the four walls inside the space, so as to reduce the influence of the air compressor noise on the indoor environment.

[0100] The molecular sieve is a kind of high-efficiency gas separation material, which can separate oxygen and nitrogen in the air. The separated oxygen is discharged into the indoor unit and discharged into the indoor along with the cooling or heating air of the indoor unit, 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 temperature of the molecular sieve oxygen production should be between 5℃-55℃. Generally, at room temperature (20℃-30℃), the adsorption capacity of the molecular sieve for nitrogen is strong, which 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 damage to the structure of the molecular sieve. Therefore, the temperature of the air coming out of the air compressor needs to be cooled. Specifically, in the embodiments of the present application, two rows of U-shaped pipes (i.e. the second gas conveying pipeline 602 and the second gas conveying pipeline 601) are designed in the condenser 200 of the outdoor unit 200 and the evaporator 100 of the indoor unit 10 respectively to connect the air compressor module 400. In the cooling condition, the low temperature of the indoor unit 10 evaporator 100 is used to cool the high temperature air coming out of the air compressor, and in the heating condition, the low temperature of the outdoor unit 20 condenser 200 is used to cool the high temperature air coming out of the air compressor. Subsequently, the air enters the molecular sieve module 500, which can greatly improve the service life and oxygen production efficiency of the molecular sieve.

[0102] The high-pressure nitrogen gas after desorption of the molecular sieve is released to the outdoor through the outdoor exhaust pipe 800, and the flow of the high-pressure nitrogen gas is used to drive the normal-temperature low-pressure air into the sealed space where the air compressor module 400 is installed, so as to cool the air compressor through the surface of the air compressor, and then the air and the nitrogen gas are discharged from the outdoor unit, which can effectively reduce the operating temperature of the air compressor and improve its working efficiency and service life.

[0103] As shown in the drawings, the air conditioner in the embodiments of the present application is an integrated air conditioner (i.e. a window type air conditioner). Figure 2 ​​As shown, in the refrigeration mode, the molecular sieve oxygen production process is: the outdoor air is filtered by the filter 902 and 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 enters the evaporator 100 of the indoor unit 10 through the first branch pipe section 600c after the first main pipe section 600a and the first reversing valve 701, and is cooled, the high-temperature and high-pressure gas becomes low-temperature and high-pressure gas and enters the second main pipe section 600b through the second branch pipe section 600d after 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 the molecular sieve reversing valve 502 and the throttle valve, and enters the indoor together with the air circulating in the indoor unit 10, and the nitrogen is adsorbed on the molecular sieve.

[0104] As shown in the refrigeration mode, Figure 3 As shown, in the heating mode, the molecular sieve oxygen production process is: the outdoor air is filtered by the filter 902 and 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 enters the condenser 200 of the outdoor unit 20 through the second branch pipe section 600d after the first main pipe section 600a and the first reversing valve 701, and is cooled, the high-temperature and high-pressure gas becomes low-temperature and high-pressure gas and enters the second main pipe section 600b through the second branch pipe section 600d after 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 the molecular sieve reversing valve 502 and the throttle valve, and enters the indoor together with the air circulating in the indoor unit 10, and the nitrogen is adsorbed on the molecular sieve.

[0105] As shown in the refrigeration mode, Figures 1-4 As shown, the molecular sieve module 500 is designed with two identical molecular sieves, which can alternately produce oxygen and desorb, reciprocate, continuously produce oxygen, and switch between the two molecular sieves through the 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, and the oxygen production equipment is started and stopped according to the oxygen concentration, and the amount of oxygen discharged into the indoor is controlled through the throttle valve.

[0107] After the molecular sieve adsorbs nitrogen, the nitrogen is desorbed by heating the molecular sieve, and the high-temperature and high-pressure nitrogen is discharged to the outdoor unit through the outdoor exhaust pipe 800, as shown in the heating mode, Figures 1-4As shown, the pipeline is designed in the middle of the "human" shaped pipeline design, 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 with nitrogen. On the one hand, it can effectively reduce the operating temperature of the air compressor, improve its working efficiency and service life. Secondly, it can reduce the discharge temperature of nitrogen to prevent disturbing the air temperature around the outdoor unit.
