Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, and specifically relates to an air-to-water device. Background Technology

[0002] An air-to-water generator, also known as an air-to-water maker or air-to-water extractor, is a water-producing device that extracts drinking water from the air. Existing air-to-water generators typically collect drinking water through multiple steps, including air filtration, air compression and condensation, water collection, and water purification. This allows for the concentration and purification of moisture in the air into clean drinking water without the need for a water source, requiring only electricity. This is significant for the conservation of water resources and in situations where there is no water source. The working principle of an air-to-water generator is to collect water molecules in the air through high-efficiency filtration and condense them into liquid water.

[0003] In related technologies, existing air-to-water generators will frost up in low-temperature environments, preventing them from producing water around the clock. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide an air-to-water device to solve the problem that the air-to-water generator in the prior art cannot produce water around the clock in low-temperature environments.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-to-water device, comprising: a control device, a compressor, a first heat exchanger, a second heat exchanger, a refrigerant reversing valve, and a moisture-absorbing component; the first heat exchanger and the second heat exchanger are connected through the compressor, and the first heat exchanger and the second heat exchanger are also connected through the refrigerant reversing valve; the compressor, the first heat exchanger, and the second heat exchanger are respectively connected to the control device;

[0006] The moisture-absorbing component is located between the first heat exchanger and the second heat exchanger.

[0007] In the first / second heat exchanger, the refrigerant exchanges heat with hot air, and the moisture-absorbing component absorbs water vapor from the air. The refrigerant in the first / second heat exchanger absorbs heat from the air, causing the air temperature to drop. The second / first heat exchanger exchanges heat with the ambient air absorbed by the moisture-absorbing component, transferring the heat from the refrigerant to the environment and obtaining liquid water. The refrigerant reversing valve is used to switch the refrigerant's circuit flow direction, realizing the switching between cooling and heating between the first and second heat exchangers.

[0008] Furthermore, the first heat exchanger and the second heat exchanger are connected by a throttling component.

[0009] The throttling component is used to regulate the refrigerant flow rate of the first heat exchanger and the second heat exchanger.

[0010] Furthermore, it also includes:

[0011] A fan is used to provide the airflow into the air-to-water generator.

[0012] The fan is connected to the control device.

[0013] Furthermore, the refrigerant reversing valve is a four-way reversing valve;

[0014] The four-way reversing valve includes a first refrigerant reversing port, a refrigerant return port, a second refrigerant reversing port, and a refrigerant inlet port;

[0015] One end of the compressor is connected to the refrigerant inlet, one end of the first refrigerant reversing port is connected to the first heat exchanger, the other end of the first heat exchanger is connected to one end of the second refrigerant reversing port, the other end of the second refrigerant reversing port is connected to the second heat exchanger, and the refrigerant return port is connected to the other end of the compressor.

[0016] Furthermore, the effective range of the moisture-absorbing component is...

[0017] Low temperature: -5 to 15℃, low humidity: 10 to 30% RH;

[0018] High temperature: 35-45℃, high humidity: 80-95%RH.

[0019] Furthermore, when the ambient temperature exceeds the preset temperature value, the first heat exchanger is activated to produce water.

[0020] Furthermore, the preset temperature value is 18°C.

[0021] Furthermore, it also includes:

[0022] A water storage tank is used to store liquid water.

[0023] Furthermore, it also includes:

[0024] A sterilization and disinfection device is installed inside the water storage tank to sterilize and disinfect the water in the water storage tank.

[0025] The beneficial effects that can be achieved by adopting the above technical solution in this invention are as follows:

[0026] In this application, the first and second heat exchangers can absorb or release heat at any temperature, thereby preventing icing due to excessively low ambient temperatures. This enables air-to-water conversion at any temperature, unaffected by ambient temperature and humidity. Attached Figure Description

Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0029] Figure 2 This is a schematic diagram of the principle of the air-to-water device in this invention. Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] The following describes a specific air-to-water device provided in an embodiment of this application, with reference to the accompanying drawings.

[0032] like Figure 1 As shown, this embodiment provides an air-to-water device, including: a first heat exchanger 1, a second heat exchanger 2, a control device (not shown in the figure), a compressor 3, a refrigerant reversing valve 4, and a moisture absorption component 5; the first heat exchanger 1 and the second heat exchanger 2 are connected through the compressor 3, and the first heat exchanger 1 and the second heat exchanger 2 are also connected through the refrigerant reversing valve 4; the compressor 3, the first heat exchanger 1, and the second heat exchanger 2 are respectively connected to the control device;

[0033] The moisture-absorbing component 5 is located between the first heat exchanger 1 and the second heat exchanger 2.

[0034] The refrigerant in the first heat exchanger 1 / second heat exchanger 2 exchanges heat with hot air. The moisture-absorbing component 5 absorbs water vapor from the air. The refrigerant in the first heat exchanger 1 / second heat exchanger 2 absorbs heat from the air, causing the air temperature to drop. The second heat exchanger 2 / first heat exchanger 1 exchanges heat with the ambient air absorbed by the moisture-absorbing component 5, transferring the heat from the refrigerant to the environment and obtaining liquid water. The refrigerant reversing valve 4 is used to switch the refrigerant circuit flow direction, realizing the switching between cooling and heating between the first heat exchanger 1 and the second heat exchanger 2.

[0035] The working principle of the air-to-water device provided in this application embodiment is as follows: Figure 2As shown, this application involves a cycle of adsorption and desorption. The compressor 3 contains a refrigerant. After the air-to-water device starts, the compressor 3 draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via a piston, and discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle. In this application, both the first heat exchanger 1 and the second heat exchanger 2 function as evaporators and condensers simultaneously. Air passes through the first heat exchanger 1, which functions as an evaporator. The refrigerant in the first heat exchanger 1 absorbs heat from the air, causing the air temperature to drop. The cooled air then passes through the moisture-absorbing component 5, which adsorbs water vapor from the air until it becomes saturated or nearly saturated, resulting in high-humidity air. Then, the moisture-absorbing component 5 performs desorption. At this time, the second heat exchanger 2 functions as a condenser. The condenser exchanges heat with the ambient air, transferring heat from the refrigerant to the environment, causing the water vapor to condense into liquid water. This achieves thermal balance, providing both refrigeration and heating functions in a cycle, thus completing the desorption process. Then, it adsorbs again, and the cycle repeats.

[0036] In this application, the refrigerant reversing valve 4 is switched to change the refrigerant circuit flow direction, thereby realizing the cooling and heating conversion of the first heat exchanger 1 and the second heat exchanger 2.

[0037] In one embodiment, the first heat exchanger 1 and the second heat exchanger 2 are also connected by a throttling component 6;

[0038] The throttling component 6 is used to adjust the refrigerant flow rate of the first heat exchanger 1 and the second heat exchanger 2.

[0039] The throttling component 6 in this application is used to regulate the refrigerant flow rate, and it mainly achieves the functions of throttling and pressure reduction by changing the pressure.

[0040] In one embodiment, the air-to-water device further includes:

[0041] Fan 7 is used to provide a reasonable airflow into the air-to-water generator equipment;

[0042] The fan 7 is connected to the control device.

[0043] The fan 7 of this application can actively supply air to the air-to-water device, thereby producing water.

[0044] In one embodiment, the refrigerant reversing valve 4 is a four-way reversing valve;

[0045] The four-way reversing valve includes a first refrigerant reversing port 41, a refrigerant return port 42, a second refrigerant reversing port 43, and a refrigerant inlet port 44.

[0046] One end of the compressor 3 is connected to the refrigerant inlet 44, one end of the first refrigerant reversing port 41 is connected to the first heat exchanger 1, the other end of the first heat exchanger 1 is connected to one end of the second refrigerant reversing port 43, the other end of the second refrigerant reversing port 43 is connected to the second heat exchanger 2, and the refrigerant return port 42 is connected to the other end of the compressor 3.

[0047] In some embodiments, the effective range of the moisture-absorbing component 5 is...

[0048] Low temperature: -5 to 15℃, low humidity: 10 to 30% RH;

[0049] High temperature: 35-45℃, high humidity: 80-95%RH.

[0050] It is understood that the first heat exchanger 1 and the second heat exchanger 2 in this application can absorb or release heat at any temperature, thereby preventing icing due to excessively low ambient temperatures. This enables air-to-water conversion at any temperature, unaffected by ambient temperature and humidity.

[0051] It is understandable that the function of the moisture-absorbing component 5 in this application is to actively absorb water molecules in the air by utilizing the material properties, thereby increasing the absolute moisture content of the air-to-water treatment side by more than 50%.

[0052] In some embodiments, when the ambient temperature is greater than a preset temperature value, the first heat exchanger 1 is activated to produce water.

[0053] The preset temperature value is 18℃.

[0054] In some embodiments, the air-to-water device further includes:

[0055] A water storage tank (not shown in the figure) is used to store liquid water.

[0056] In this application, the system completes [operation] under low temperature and low humidity conditions. Figure 2 In the ABCD adsorption and desorption process, high-temperature and high-humidity air is condensed into liquid water by a low-temperature evaporator. When the ambient air dew point temperature is greater than 18°C, the first heat exchanger functions as an evaporator, and its cold surface temperature is controlled between 12-15°C to achieve cooling, condensation, and water production. At this time, it is not necessary to complete the entire cycle of adsorption and desorption; only the AB process needs to be completed to achieve air-to-water production, thus improving water production efficiency.

[0057] Air-to-water equipment also includes:

[0058] A sterilization and disinfection device (not shown in the figure) is installed in the water storage tank to sterilize and disinfect the water in the water storage tank.

[0059] Understandably, this application also includes a sterilization and disinfection device to sterilize and disinfect the formed liquid water.

[0060] In summary, the present invention provides an air-to-water device. This application achieves heat absorption and release through a first heat exchanger and a second heat exchanger, thereby preventing frost or ice formation caused by excessively low ambient temperatures, and thus realizing air-to-water generation at any ambient temperature.
