DETAILED DESCRIPTION

[0043] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0044] In the related art, in order to ensure the constant temperature and humidity production conditions, a fresh air conditioner is usually used to adjust the humidity and temperature in the production workshop, so that the air in the workshop meets the temperature and humidity requirements. When the fresh air conditioner uses a humidification module to humidify fresh air, it will take away most of the heat of the fresh air, resulting in a significant reduction in the temperature of the fresh air. The fresh air conditioner needs to heat the fresh air again, increasing energy consumption and having poor energy saving effect.

[0045] To improve the above problems, please refer to Figure 1 and Figure 2 The present application provides a fresh air conditioner, which is applied to a workshop. The fresh air conditioner comprises an air duct assembly 100 and a humidification module 200.

[0046] The air duct assembly 100 serves as an air inlet channel of the fresh air conditioner, having an air inlet 110 and an air outlet 120. The air inlet 110 is located outside the workshop, so that the air outside the workshop can enter the air duct assembly 100 through the air inlet 110. The air outlet 120 is located inside the workshop, so that the air entering the air duct assembly 100 can enter the workshop through the air outlet 120, delivering fresh air to the workshop and thus improving the air quality in the workshop. The air duct assembly 100 is usually made of metal materials, such as stainless steel, galvanized steel, etc. These materials have good durability and can effectively resist physical impact and environmental erosion from the outside world, ensuring long-term stable operation of the fresh air system in the workshop. The air duct assembly 100 comprises a humidity adjustment section 130.

[0047] The humidification module 200 is arranged in the humidity adjustment section 130 of the air duct assembly 100, and is used to humidify the fresh air flow passing through the humidity adjustment section 130, adjust the humidity of the fresh air, and make the fresh air meet the humidity requirements of the workshop.

[0048] Please refer to Figure 2The humidification module 200 comprises a humidification assembly 210 and a heating assembly 220. The humidification assembly 210 comprises, but is not limited to, a humidifier 211, a wet film 212 or a humidification net, etc., which is configured to humidify the airflow flowing therethrough to achieve the effect of adjusting the humidity.

[0049] The heating assembly 220 is at least partially arranged in the humidification assembly 210 and is configured to heat the humidification assembly 210. The arrangement of the heating assembly 220 can, on the one hand, increase the temperature of the humidification assembly 210, so that the water in the humidification assembly 210 is more likely to vaporize, thereby improving the humidification effect of the humidification assembly 210; on the other hand, can reduce the temperature difference of the fresh air flow before and after passing through the humidification assembly 210, thereby reducing the heat consumption of the fresh air flow flowing through the humidification assembly 210.

[0050] The present application can heat the humidification assembly 210 by arranging the heating assembly 220 in the humidification assembly 210, thereby increasing the temperature of the humidification assembly 210, so that the water in the humidification assembly 210 is more likely to vaporize, thereby improving the humidification effect of the humidification assembly 210; in addition, the temperature difference of the fresh air flow before and after passing through the humidification assembly 210 can be reduced, thereby reducing the heat consumption of the fresh air flow flowing through the humidification assembly 210 and improving the energy saving effect.

[0051] In some embodiments, referring to Figure 2 The humidification assembly 210 comprises the humidifier 211 and the wet film 212. The humidifier 211 is arranged in the humidity adjustment section 130 and is configured to humidify the airflow flowing through the humidity adjustment section 130. It should be noted that the type of the humidifier 211 is not limited in the present application. For example, the humidifier 211 can be a high-pressure micro-fog humidifier 211; or the humidifier 211 can also be a drop-type humidifier 211.

[0052] Further, the humidifier 211 can humidify the fresh air flow once, and the wet film 212 is arranged in the humidity adjustment section 130 and is located downstream of the humidifier 211. The wet film 212 can humidify the airflow flowing therethrough twice, thereby improving the humidification effect of the humidification assembly 210. It should be noted that the structure of the wet film 212 is not limited in the present application. For example, the wet film 212 can be a multi-layer three-dimensional honeycomb structure; or the wet film 212 can also be a corrugated structure. The wet film 212 adopts these structures, which can increase the contact area of the airflow and the wet film 212, thereby further improving the humidification effect. In addition, the material of the wet film 212 is not limited in the present application. For example, the wet film 212 can be wood pulp fiber, cotton fiber, etc., which has the advantages of low cost and environmental protection and biodegradability. For another example, the wet film 212 can also be PP (polypropylene), ABS resin, etc., which has the advantages of good durability and long service life.

[0053] When the humidifier 211 is humidifying the new air flow, part of the humidified water mist generated by the humidifier 211 is not effectively evaporated into the air flow, resulting in that the part of the water mist is not converted into air humidity, causing ineffective humidification. Based on the structural layout of the humidification assembly 210, the wet membrane 212 is arranged downstream of the humidifier 211, which can absorb the water mist of ineffective humidification and use the water mist of ineffective humidification to humidify itself, avoiding waste; in addition, when the new air flow passes through the wet membrane 212, the wet membrane 212 can perform secondary humidification on the new air flow, improving the uniformity and stability of humidification, and further improving the humidification effect.

[0054] In some embodiments, the fresh air air conditioner further comprises a process cooling module (not shown in the figure), which is arranged outside the air duct assembly 100 and is used for cooling the equipment (such as production machine tools, etc.) in the workshop and absorbing heat. Specifically, the process cooling module can have various structures, including but not limited to a compression cycle system, a liquid cooling system, or an evaporative cooling system, etc.

[0055] In specific embodiments, the process cooling module comprises a cooling pipeline (not shown in the figure) and a liquid storage tank (not shown in the figure). The cooling pipeline is used for circulating refrigerant, and by heat exchange with the equipment in the workshop, absorbs the heat generated by the equipment in operation, cools the equipment and cools the equipment in the workshop.

[0056] The liquid storage tank is used to store the refrigerant and maintain the continuous flow and pressure stability of the refrigerant through a circulating pump. When the refrigerant flows through the cooling pipeline, the temperature of the refrigerant rises after absorbing the heat of the equipment in the workshop, and then the refrigerant returns to the liquid storage tank, which usually needs to rely on an external heat dissipation device for cooling, and then re-enters the cycle, thereby achieving heat dissipation of the equipment in the workshop.

[0057] It should be noted that the type of refrigerant is not limited in the present application, and those skilled in the art can adjust it flexibly according to the actual product situation. For example, the refrigerant can be a liquid refrigerant; wherein the liquid refrigerant includes but is not limited to water, brine, glycol solution, etc. For example, the refrigerant can also be a gaseous refrigerant; wherein the gaseous refrigerant includes but is not limited to air, freon, etc.

[0058] In some embodiments, in combination with reference to Figure 1 and Figure 2The heating assembly 220 comprises a heating pipeline 221 which is at least partially arranged in the wet membrane 212 for heating the wet membrane 212. The heating pipeline 221 penetrates the air duct wall of the air duct assembly 100 so that the inlet end and the outlet end of the heating pipeline 221 are both located outside the air duct assembly 100. It can be understood that the heating pipeline 221 can be a heat exchange pipe and can further comprise heat exchange fins. Based on the above arrangement, when the wet membrane 212 is heated by the heating pipeline 221, the water in the wet membrane 212 is more likely to be vaporized, thereby improving the humidifying effect of the wet membrane 212. In addition, when the airflow flows through the wet membrane 212, the temperature of the airflow will not be greatly reduced, thereby reducing the temperature difference of the fresh air before and after passing through the humidifying assembly 210 and reducing the heat consumption when the airflow flows through the humidifying assembly 210.

[0059] Specifically, the inlet end of the heating pipeline 221 is in communication with the cooling pipeline, and the outlet end of the heating pipeline 221 is in communication with the liquid storage tank, so that the refrigerant in the process cooling module can flow into the heating pipeline 221, and the refrigerant in the cooling pipeline is used as the working medium in the heating pipeline 221. Through the above arrangement, on the one hand, the temperature of the refrigerant in the cooling pipeline is ingeniously used to heat the wet membrane 212, thereby improving the humidifying effect of the wet membrane 212. On the other hand, while the refrigerant heats the wet membrane 212, the temperature of the refrigerant can be effectively reduced, thereby reducing the dependence on external heat dissipation devices for cooling the refrigerant and further reducing energy consumption.

[0060] In some embodiments, referring to Figure 2 , along the air supply direction of the airflow in the air duct assembly 100, the heating pipeline 221 divides the wet membrane 212 into a windward part 2121 and an air outlet part 2122. The thickness of the windward part 2121 is greater than or equal to the thickness of the air outlet part 2122.

[0061] Specifically, in one embodiment, when the humidifier 211 is a high-pressure micro-fog humidifier 211, the humidified water mist generated by the high-pressure micro-fog humidifier 211 is diffused along the air supply direction. When the wet membrane 212 is humidified by the high-pressure micro-fog humidifier 211, the water mist needs to pass through the windward part 2121 and the heating pipeline 221 in sequence before reaching the air outlet part 2122. After passing through the heating pipeline 221, the water mist evaporates a lot, and most of the water mist cannot enter the air outlet part 2122. In order to reduce the evaporation amount of the water mist by the heating pipeline 221 and ensure the humidifying effect, the thickness of the windward part 2121 needs to be greater than the thickness of the air outlet part 2122, so that the water content of the windward part 2121 is higher than that of the air outlet part 2122, thereby enabling the water mist to smoothly reach the air outlet part 2122. For example, the thickness of the windward part 2121 is 15 cm, and the thickness of the air outlet part 2122 is 5 cm.

[0062] In addition, in an alternative embodiment, when the humidifier 211 is a drip-type humidifier 211, since the humidified water mist generated by the drip-type humidifier 211 is not all diffused in the air supply direction, part of the water mist is diffused in the radial direction of the air duct assembly 100. When the wet film 212 is humidified by using the drip-type humidifier 211, part of the water mist needs to pass through the windward part 2121 and the heating pipeline 221 in turn to reach the air outlet part 2122, and the other part of the water mist can directly reach the air outlet part 2122. The humidification of the wet film 212 by the drip-type humidifier 211 is more uniform, so the thickness of the windward part 2121 can be equal to the thickness of the air outlet part 2122, for example, the thickness of the windward part 2121 is 10 cm, and the thickness of the air outlet part 2122 is 10 cm.

[0063] In summary, it can be understood that the setting size of the thickness of the windward part 2121 and the air outlet part 2122 is not fixed, and the person skilled in the art can flexibly adjust the setting according to the actual product situation.

[0064] In some embodiments, referring to Figure 2 The fresh air conditioner further comprises a dehumidification module 600. The dehumidification module 600 is arranged in the humidity adjustment section 130 and is located downstream of the humidification module 200, and is used for dehumidifying the airflow passing through the humidity adjustment section 130. The dehumidification module 600 can have various structures, such as a condensation dehumidifier, a rotary dehumidifier, a solution dehumidifier, etc. They usually include a moisture absorbing element, a regeneration device and a humidity control device. The moisture absorbing element removes moisture in the air by condensation, adsorption or absorption, etc. The regeneration device is used to restore the dehumidification capacity of the moisture absorbing element (such as heating to desorb moisture or concentrating solution), and the humidity control device is used to monitor and control the humidity of the airflow, so as to realize the control of the humidity of the airflow. When the fresh air flow passes through the dehumidification module 600, the moisture in the air is adsorbed by the moisture absorbing element, thereby realizing the dehumidification of the fresh air flow.

[0065] It is worth mentioning that in the embodiments of the present application, the humidification module 200 and the dehumidification module 600 in the humidity adjustment section 130 can be operated simultaneously or not simultaneously. For example, in the case that the humidity of the environment outside the workshop is lower than the required humidity of the workshop, but after the fresh air flow passes through the humidification module 200, the humidity of the fresh air flow is higher than the required humidity of the workshop, at this time, the humidification module 200 and the dehumidification module 600 need to be operated simultaneously. Or, in the case that the humidity of the environment outside the workshop is higher than the required humidity of the workshop, the humidification module 200 can also not work, and the dehumidification module 600 works to dehumidify, which can be adjusted and set according to the actual situation.

[0066] In some embodiments, referring to Figure 1The air duct assembly 100 further comprises a first temperature adjustment section 140, which is arranged at one side of the humidity adjustment section 130 close to the air inlet 110 and is in communication with the air inlet 110 and the humidity adjustment section 130 respectively, so that the airflow of the fresh air can enter the first temperature adjustment section 140 through the air inlet 110 and then enter the humidity adjustment section 130 after flowing through the first temperature adjustment section 140.

[0067] Further, in the first temperature adjustment section 140, along the air supply direction, the fresh air conditioner further comprises an electric preheating module 300, a primary filter module 400 and a heating module 500 arranged in sequence.

[0068] The electric preheating module 300 is arranged in the first temperature adjustment section 140 and is used for primary heating the airflow entering the air duct assembly 100 through the air inlet 110. The electric preheating module 300 usually contains one or more electric heating elements (such as electric heating wires, electric heating sheets, etc.), which are encapsulated in high-temperature-resistant and insulating materials. When electric current passes through the electric heating elements, the electric heating elements generate heat and transfer the heat to the passing airflow, thereby achieving preheating of the fresh air airflow.

[0069] The primary filter module 400 is arranged in the first temperature adjustment section 140 and is located downstream of the preheating module, and is used for primary filtering the airflow passing through the electric preheating module 300. The primary filter module 400 can be a primary efficiency panel filter or a filter layer composed of one or more filter materials (such as paper filter screen, non-woven fabric, activated carbon, etc.) and a frame supporting these filter layers. When the fresh air airflow passes through the filter layer or the primary efficiency panel filter, large-particle impurities are intercepted by the filter materials, thereby achieving primary filtering of the fresh air airflow.

[0070] The heating module 500 is arranged in the first temperature adjustment section 140 and is located downstream of the primary filter module 400, and is used for heating the airflow passing through the primary filter module 400. The heating module 500 can have various structures, such as electric heating pipes, PTC ceramic heating bodies, heat pumps, etc. They usually include heating elements, heat sinks and temperature control devices. The heating elements generate heat, which is transferred to the passing airflow through the heat sinks, thereby achieving heating of the fresh air airflow. The temperature control devices are used for monitoring and controlling the temperature of the airflow.

[0071] In some embodiments, referring to Figure 1 The air duct assembly 100 further comprises a second temperature adjustment section 150, which is arranged at one side of the humidity adjustment section 130 close to the air outlet 120 and is in communication with the humidity adjustment section 130 and the air outlet 120 respectively, so that the fresh air airflow can enter the second temperature adjustment section 150 after flowing through the humidity adjustment section 130 and be delivered to the workshop through the air outlet 120.

[0072] Further, in the second temperature adjustment section 150, along the air supply direction, the fresh air conditioner further comprises a reheating module 700, a fan module 800 and a re-filtering module 900 arranged in sequence.

[0073] The reheating module 700 is arranged in the second temperature adjustment section 150 and is used to reheat the air flow passing through the humidity adjustment section 130. The structure of the reheating module 700 can be the same as that of the heating module 500. Specifically, the reheating module 700 can have various structures, such as an electric heating tube, a PTC ceramic heating body, a heat pump, etc. They usually include a heating element, a heat sink and a temperature control device. The heating element generates heat, which is transferred to the passing air flow through the heat sink to heat the fresh air flow. The temperature control device is used to monitor and control the temperature of the air flow.

[0074] The fan module 800 is arranged in the second temperature adjustment section 150 and is located downstream of the reheating module 700 and is used to drive the air flow. The fan module 800 includes a fan that accelerates the air flow entering the air duct assembly 100 so that the air flow in the air duct assembly 100 can be quickly delivered to the workshop. By adjusting the rotating speed of the motor in the fan, the flow rate and speed of the fresh air flow can be controlled to adapt to different workshop requirements and operating conditions.

[0075] The re-filtering module 900 is arranged in the second temperature adjustment section 150 and is located downstream of the fan module 800 and is used to re-filter the air flow. The re-filtering module 900 can be similar to the primary filtering module 400, but the filtering precision of the re-filtering module 900 is lower than that of the primary filtering module 400. Therefore, the re-filtering module 900 is usually made of more fine filtering material to remove small particles and pollutants in the air flow. When the air flow passes through the fine filtering layer, the small particles and pollutants are trapped by the filtering material, thereby achieving re-filtering of the fresh air flow.

[0076] It is worth mentioning that in the embodiments of the present application, the fresh air flow is processed by the cooperation between the modules, so that the temperature and humidity in the workshop are maintained within the required range, and a constant temperature and humidity environment is created to ensure the production quality.

[0077] More specifically, the electric preheating module 300, the primary filtering module 400, the heating module 500, the humidifying module 200, the dehumidifying module 600, the reheating module 700, the fan module 800 and the re-filtering module 900 can be operated simultaneously or only some of them can be operated. For example, in the case where the ambient temperature outside the workshop is higher than the required temperature of the workshop, the electric preheating module 300 can not work; or in the case where the ambient humidity outside the workshop is higher than the required humidity of the workshop, the humidifying module 200 can not work. The specific settings can be adjusted according to the actual situation.

[0078] In some embodiments, a temperature and humidity sensor (not shown in the figure) is further arranged in the air duct assembly 100, and is used to detect the temperature and humidity of the fresh air flow in the air duct assembly 100. The temperature and humidity sensor can assist the electric preheating module 300, the heating module 500 and the reheating module 700 in adjusting the temperature, and can also assist the humidifying module 200 and the dehumidifying module 600 in adjusting the humidity, so as to realize accurate control of the temperature and humidity of the fresh air. The temperature and humidity sensor can be an integrated sensor that simultaneously detects the temperature and humidity of the fresh air flow, or a temperature sensor and a humidity sensor can be separately arranged, and the temperature sensor and the humidity sensor are respectively used to detect the temperature and humidity of the fresh air flow.

[0079] In some embodiments, a fresh air valve (not shown in the figure) is arranged at the air inlet 110 of the air duct assembly 100, and is used to adjust the fresh air inlet amount, so as to realize accurate control of the fresh air amount, and under the condition of meeting the air environment requirements of the workshop, the energy consumption is reduced as much as possible, and energy waste is avoided. The type of the fresh air valve includes but is not limited to an electric fresh air valve and a manual fresh air valve.

[0080] In addition, a silencer (not shown in the figure) can be arranged near the air outlet 120 of the air duct assembly 100, and is used to absorb the noise during the operation of the entire air duct assembly 100, so as to reduce the operation noise of the fresh air conditioner. The type of the silencer includes but is not limited to a resistive silencer and a reactive silencer.
