DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0023] like Figure 1 The present embodiment provides a water capture device, including a rotor 4, a first fan 1, a second fan 12, a primary cooler 2, a secondary cooler 11, a heater 7, a heat pump evaporator 10, a heat pump condenser 6, a three-way valve 13 and a water treatment component 19. The rotor 4 is provided with an air inlet, a first working port, a second working port and an exhaust port. The exhaust port is placed outside in the air.

[0024] The air outlet of the first fan 1 is connected to the primary cooler 2, and the primary cooler 2 is connected to the working port 2 of the rotor 4. The air inlet of the second fan 12 is connected to the secondary cooler 11. The secondary cooler 11 is connected to the heat pump evaporator 10, and the heat pump evaporator 10 is connected to the working port 1 of the rotor 4. The air inlet of the rotor 4 is connected to the heater 7. The heater 7 is connected to the heat pump condenser 6. The three-way valve 13 includes a first valve port 14, a second valve port 15 and a third valve port 16. The first valve port 14 is installed between the air outlet of the first fan 1 and the primary cooler 2. The second valve port 15 is installed at the air outlet of the second fan 12, and the third valve port 16 is placed outside the air. In actual implementation, the switch adjustment of the three valve ports can be manually or electrically controlled to assist the water capture device in smoothly capturing water. The water treatment component 19 is used to collect the generated water of the secondary surface cooler 11 or the heat pump evaporator 10, that is, the water treatment component 19 needs to be able to be movably arranged below the secondary surface cooler 11 or the heat pump evaporator 10, so that it can be flexibly moved and acted between the secondary surface cooler 11 or the heat pump evaporator 10. This moving method adopts the existing moving structure, which is not explained in detail. The role of the water treatment component 19 depends on the specific situation. If the ambient humidity is high, the secondary surface cooler 11 is not needed, and the water in the desorbed air can be analyzed out by the cooling capacity of the heat pump evaporator 10 alone, and it is connected to the heat pump evaporator. If the humidity is low, a lower temperature is required to analyze the water in the desorbed air, then it is connected under the secondary surface cooler 11, and the heat pump evaporator 10 only plays a pre-cooling role. The third valve port 16 is placed in the air for two functions. The first is to prevent the desorbed air from condensing and releasing water, and the absolute moisture content is lower than that of the ambient air (the refrigerant in the cooler first enters the secondary cooler 11, exchanges heat with the desorbed air in the secondary cooler 11, and then enters the primary cooler 2, so the refrigerant temperature in the secondary cooler 11 is lower); at this time, the desorbed air after the water is released is directly discharged to the environment or indoors for cooling; the second function is to use the water capture device provided in the present application as a compression refrigeration water capture device to discharge the condensed air directly to the outdoors or to cool the rooms. In this process, due to the reversal of the wind direction of the first fan 1, the air cannot be discharged to the outdoors through the first fan 1.

[0025] Optionally, the water treatment assembly 19 includes a water intake device, a filter 21 and a disinfection water tank 22. The water intake device and the filter 21 are connected to obtain the water source discharged from the secondary surface cooler 11 or the heat pump evaporator 10. The filter 21 is connected to the disinfection water tank 22. After the water intake device receives the water source discharged from the secondary surface cooler 11, it is transported to the filter 21 for filtration, and then enters the disinfection water tank 22 for storage and disinfection.

[0026] Specifically, the water intake device includes a water intake funnel 20. The water intake funnel 20 includes a water intake port and a water outlet. The water intake port is arranged directly below the drain port of the secondary surface cooler 11, and can conveniently receive the water generated by the secondary surface cooler 11. The water outlet is connected to the filter 21.

[0027] Optionally, the water capture device further includes a first temperature probe 8, a second temperature probe 9, a third temperature probe 3 and a fourth temperature probe 5. Among them, the first temperature probe 8 is installed at the working port 1 of the runner 4, and the second temperature probe 9 is installed at the air inlet of the runner 4. The third temperature probe 3 is provided at the working port 2 of the runner 4, and the fourth temperature probe 5 is provided on the exhaust port of the runner 4. After the heat pump condenser 6 and the heater 7 process the air, the second temperature probe 9 detects a first temperature value of the air. The air continues to enter the runner 4 and is discharged through the working port 1 under the action of the runner 4. At the same time, the first temperature probe 8 detects a second temperature value of the discharged air. Next, the air continues to enter the heat pump evaporator 10, is acted upon by the heat pump evaporator 10 and enters the secondary surface cooler 11, and the steam is condensed to form condensed water which is collected by the water treatment component 19. The air passes through the second valve port 15 and the first valve port 14 of the three-way valve 13 through the second fan 12, and under the blowing action of the first fan 1, flows to the primary condenser 2 and enters the rotor 4 for processing and action, and is discharged from the exhaust port. Before entering the rotor 4, the third temperature probe 3 detects the third temperature value of the air, and when discharged from the exhaust port, the fourth temperature probe 5 detects the fourth temperature value of the air again.

[0028] Specifically, the complete adsorption and desorption process is as follows: Adsorption process: The ambient air is driven by the first fan 1 and cooled by the primary surface cooler 2. At this time, the air temperature decreases, the relative humidity increases, and the absolute moisture content remains unchanged. When passing through the rotor 4, the moisture in the air is adsorbed by the rotor, the air temperature increases (the adsorption process is an exothermic process), and the relative humidity and absolute moisture content decrease.

[0029] Desorption process: air passes through the heat pump condenser 6, at this time the air temperature increases, the relative humidity decreases, and the absolute moisture content remains unchanged, after secondary heating by the heater 7, the process is the same as above, the high temperature and low humidity air passes through the rotor that adsorbs the moisture in the air and evaporates the moisture adsorbed on the rotor away, at this time the air temperature decreases (the desorption process is an endothermic process), the relative humidity and absolute moisture content of the air increase, after passing through the heat pump evaporator 10 the air temperature further decreases, the relative humidity increases, the absolute moisture content remains unchanged, after passing through the secondary surface cooler 11, the humid air decreases to below the dew point temperature, the water in the air is analyzed out, the absolute moisture content of the air decreases, and the relative humidity remains unchanged, thus completing an adsorption and desorption cycle.

[0030] Optionally, a first switch valve 17 is installed between the secondary surface cooler 11 and the heat pump evaporator 10, and a second switch valve 18 is installed on the secondary surface cooler 11. When the ambient humidity is high, water can be directly taken from the air by refrigeration, and the runner 4 does not need to work. At this time, the first switch valve 17 needs to be closed and the second switch valve 18 needs to be opened. Direct refrigeration water extraction in a high humidity environment is more energy-efficient.

[0031] When the matching components of the water capture device provided by the present application and the three-way valve 13 cooperate with each other to realize the combination of the four modes, the specific operation is as follows:

[0032] 1. For high temperature and extremely low humidity areas (absolute humidity in the air <8g / kg is a non-fixed value, depending on the temperature of the first and / or second stage cooler):

[0033] When the water capture device is started, first turn on the first fan 1, close the first valve port 14 of the three-way valve 13, turn on the first-stage surface cooler 2, and turn on the rotor 4 for adsorption. During this period, the corresponding humidity is obtained according to the temperature difference between the first temperature probe 8 and the second temperature probe 9, time, or the humidity probe is set at the corresponding position as the judgment standard for whether the rotor 4 is adsorbed to saturation. When adsorbed to saturation, open the first valve port 14 of the three-way valve 13, close the third valve port 16 of the three-way valve 13, open the first switch valve 17, close the second switch valve 18, turn on the second fan 12, the second-stage surface cooler 11, the heat pump condenser 6, and the heat pump evaporator 10. At this time, the water capture system starts to automatically capture moisture in the air and filter out pure water. Comparison of the first temperature value and the second temperature value generated by the first temperature probe 8 and the second temperature probe 9, when the temperature is close to and stable, proves that the wheel 4 has excessively desorbed, and it is necessary to close the heat pump condenser 6, the heat pump evaporator 10, the second fan 12, the secondary surface cooler 11 and the first valve port 14 of the three-way valve 13, and perform the adsorption process alone, and repeat this process.

[0034] 2. For high temperature and low humidity areas (the absolute humidity content in the air is not a fixed value when it is 8-12g / kg, depending on the temperature of the surface cooler), two water capture solutions are provided for such working conditions:

[0035] 1. Only the second fan 12 and the secondary surface cooler 11 are turned on, the first switch valve 17 is closed, and the second switch valve 18 is opened, and the unit is used as a compressor-type condensing water collector. This solution can collect water with lower energy consumption.

[0036] 2. Close the first valve port 14 of the three-way valve 13, open the second valve port 15, open the first switch valve 17, close the second switch valve 18, start the first fan 1, the second fan 12, the first-level surface cooler 2, the second-level surface cooler 11, the heat pump condenser 6 and the heat pump evaporator 10, start the wheel 4, and then the water capture device starts to automatically capture moisture in the air and filter out pure water. This process is mainly aimed at high temperature and low humidity conditions, and the water capture efficiency is 2-3 times that of the first water capture scheme.

[0037] 3. For low temperature and low humidity areas (areas where the temperature is lower than the chilled water temperature of the surface cooler, the absolute moisture content is low, and the relative humidity is high):

[0038] This control process is similar to the first solution. At this time, the first-level surface cooler 2 and the second-level surface cooler 11 are closed, and the water treatment component 19 (water intake funnel 20) is moved below the heat pump evaporator 10. At the same time, the heater 7 needs to be turned on to assist heating for desorption. In dry areas, water capture can also be used continuously, and the drive wheel 4 is driven to rotate. The first fan 1 and the second fan 12 are operated at the same time, which can realize the process of continuous water capture and water intake.

[0039] 4. Dry Areas

[0040] The drive wheel 4 works, and the first fan 1 and the second fan 12 operate simultaneously, so that a continuous water collection and water intake process can be realized.
