Description

Technical Field

[0001] The invention relates to a water production device, in particular to a novel wide-operating-condition composite water production device. Background Art

[0002] As a new type of clean water collection method, air-to-water has attracted worldwide attention. It has been widely used in water-scarce areas of the world, and its application in Africa is particularly significant. It can solve the drinking water problem in areas lacking both surface water and groundwater, and is the development direction of comprehensive utilization of energy and resources in the future. At present, there are two main methods for making water from the air: one is condensation of the refrigeration system to make water, and the other is rotary dehumidifier to make water. Both methods have their own advantages and disadvantages. The condensation of the refrigeration system cannot make water from the air when the ambient temperature and humidity are low; the power consumption of the rotary dehumidifier is relatively large, and the comprehensive energy efficiency is not high.

[0003] The general standard working condition for water production is 30℃, 80%RH, under which the dew point of water is 26.19℃, and under the working condition of 5℃, 20%RH, under which the dew point of water is -16.1℃, and the dew point of water in this working condition is already in a frosted state; it can be concluded that when the dew point is low, and thus when the absolute water content is low, it will become very difficult to produce water; the general water production mechanism has an unadjustable cooling capacity, an unadjustable air intake or can only be adjusted to a limited extent, and it is impossible to achieve the optimal water production temperature of the actual environmental conditions on the fin surface of the evaporator within a wider range of working conditions. In some actual working conditions, the dew point of water cannot be reached, and water cannot be discharged. In some actual working conditions, the dew point of water can be close to the dew point of water, and a small amount of water can be discharged. In a small amount of actual working conditions, the dew point of water can be reached, and water can be discharged; the working conditions applicable to ordinary water production mechanisms on the market at present are applicable to a small amount of environmental conditions with a high absolute content of water in the air, so the applicable conditions are limited. If ordinary water-making mechanisms on the market are used to forcibly make water under certain actual working conditions, the power consumption of the water-making mechanisms is very large and the water-making effect is very poor. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a novel wide-operating-condition composite water production device. The novel wide-operating-condition composite water production device can produce liquid water from air under the condition of a wide range of environmental absolute humidity changes, and is suitable for water production under various common environmental conditions.

[0008] The water-making mechanism comprises an evaporator, a variable frequency compressor, a condenser, a water receiving pan, a water outlet pipe and a fan. The evaporator, the variable frequency compressor and the condenser are sequentially connected to form a refrigeration circuit for refrigerant circulation. A water receiving pan is provided on the lower side of the evaporator of the water-making mechanism. The water outlet pipe connects the bottom of the water receiving pan and the water storage tank. The wet air outlet of the total heat exchanger is aligned with the evaporator of the water-making mechanism. The fan discharges the air in the water-making mechanism into and out of the water-making mechanism.

[0009] The solenoid valve group includes a first solenoid valve and a second solenoid valve. The first solenoid valve is arranged on the pipeline between the inlet of the flow distributor and the wet air inlet of the heat exchanger, and the second solenoid valve is arranged on the pipeline between the regeneration air outlet of the rotary dehumidifier and the wet air inlet of the heat exchanger.

[0010] Preferably, the fan first exchanges heat with the evaporator of the water-making mechanism for the air flowing out of the wet air outlet of the total heat exchanger, and then discharges the air out of the water-making mechanism after passing through the variable frequency compressor and the proximal area of ​​the condenser.

[0011] Preferably, the first solenoid valve and the second solenoid valve have an interlocking mechanism.

[0012] Preferably, the water-making mechanism also includes an outer shell having an insulation layer, and the evaporator, variable frequency compressor, condenser, water receiving tray and fan are all arranged in the outer shell. One end of the water outlet pipe is connected to the bottom of the water receiving tray, and the other end of the water outlet pipe passes through the outer shell and is connected to the water tank. The outer shell is provided with an air inlet and an air outlet.

[0013] Preferably, a first temperature sensor and a first humidity sensor are provided at the air inlet hole of the shell of the water making mechanism.

[0014] Preferably, a speed-adjustable wet air fan is provided in front of the wet air outlet in the total heat exchanger, and a speed-adjustable cooling air fan is provided in front of the cooling air outlet in the total heat exchanger.

[0015] Preferably, a second temperature sensor and a second humidity sensor are provided at the cooling air inlet of the total heat exchanger.

[0016] Preferably, the water production mechanism is provided with a third temperature sensor near the evaporator.

[0017] Working principle of the present invention:

[0018] In the low humidity working mode, air passes through the cyclone separator and enters the rotary dehumidifier through the flow distributor to convert the low-humidity air into high-humidity air, which is discharged from the regeneration air outlet of the rotary dehumidifier and enters the heat exchanger. After being cooled by the ambient air in the heat exchanger, the temperature is further reduced and the air enters the water-making mechanism to make water. Frost forms on the surface of the evaporator. When the thickness of the frost reaches the set thickness, the new wide-operating-condition composite water-making device starts to defrost. The defrosting method can be designed according to actual needs. Liquid water is obtained after defrosting and the produced water is stored in the water tank to complete the water production. The working state of the water-making mechanism is frost making and defrosting water making, and the absolute humidity of the ambient air is very low.

[0019] In the medium humidity working mode, air passes through the cyclone separator and enters the rotary dehumidifier through the flow distributor to convert low-humidity air into high-humidity air, which is discharged from the regeneration air outlet of the rotary dehumidifier and enters the heat exchanger. After being cooled by the ambient air in the heat exchanger, the temperature is further reduced and enters the water making mechanism to make water. It is condensed into liquid water on the surface of the evaporator and the produced water is stored in the water tank to complete the water production. The working state of the water making mechanism is liquid water production.

[0020] In the high humidity working mode, air passes through the cyclone separator and enters the heat exchanger, and then enters the water-making mechanism to make water. The air is condensed into liquid water on the surface of the evaporator, and the made water is stored in the water tank to complete the water production. The working state of the water-making mechanism is liquid water production, and the absolute humidity of the ambient air is very high.

[0021] Advantages of the present invention:

[0022] The present invention uses a rotary dehumidifier to increase the relative humidity of water in the air, so that the ambient air with lower humidity can increase the relative humidity of the air at the regeneration air outlet after passing through the rotary dehumidifier, and at the same time increase the temperature of the air at the regeneration air outlet, which reduces the difficulty of further water production and reduces the power consumption of the water production mechanism. The present invention adds a heat exchanger between the rotary dehumidifier and the water production mechanism. Since the ambient temperature is usually lower under lower ambient air humidity, this heat exchanger uses ambient air to cool the air at the regeneration air outlet of the rotary dehumidifier, and reduces the air temperature reaching the inlet of the water production mechanism, so that the water production mechanism with lower power consumption can also produce water under better conditions. Since the actual working condition is a changing environment, the present invention uses a variable frequency compressor and a variable speed fan to achieve the optimal water production state under the condition of minimum power consumption.

[0023] The present invention can continuously produce water with the lowest energy consumption under the absolute humidity conditions of a wide range of environments. The cyclone separator provides the system with impurity-free air, ensuring the stable and long-term normal working conditions of the system equipment, reducing the maintenance cost, and at the same time, improving the efficiency of air intake, and can reduce the temperature of the air intake while filtering. The rotary dehumidifier converts low-humidity air into high-humidity air, and the heat exchanger makes full use of the ambient air to cool the wet air provided by the rotary dehumidifier. The water-making mechanism uses a liquid water-making mode or a defrosting water-making mode to produce water, and the water in the air is greatly produced;

[0024] The water production mode of the present invention is determined by the actual conditions of the environment. The optimal water production mode is selected to produce water. When the absolute humidity of the environment is high, the system is operated in the state of the rotary dehumidifier in the liquid water production mode. The rotary dehumidifier is stopped, the first electromagnetic air valve is opened, the second electromagnetic air valve is closed, the rotary dehumidifier and the flow distributor are in a stopped state, and the wet air directly passes through the cyclone separator, passes through the first electromagnetic air valve, and directly enters the wet air inlet of the heat exchanger to provide wet air for the water production mechanism;

[0025] When the absolute humidity of the environment is low, the system is operated in the state of the rotary dehumidifier in the liquid water production mode, the rotary dehumidifier is started, the first electromagnetic valve is closed, and the second electromagnetic valve is opened. The rotary dehumidifier and the flow distributor are in working state, and the air flows through the flow distributor and the rotary dehumidifier.

[0026] When the absolute humidity of the environment is very low, the defrosting water-making mode is adopted. At this time, the rotary dehumidifier is started, the first electromagnetic air valve is closed, and the second electromagnetic air valve is opened. The rotary dehumidifier and the flow distributor are in working state, and the air flows through the flow distributor and the rotary dehumidifier.

[0027] In addition, the high-humidity air flowing out from the wet air outlet of the total heat exchanger first exchanges heat with the evaporator of the water-making mechanism, and the high-humidity air becomes dry low-temperature air. The dry low-temperature air then passes through the variable frequency compressor and the proximal area of ​​the condenser and is discharged from the water-making mechanism, which can reduce the air temperature around the compressor and condenser and improve the cooling efficiency of the water-making mechanism.

[0031] like Figures 1 to 3 Shown

[0032] The novel wide-operating-condition composite water-making device comprises a cyclone separator 1, a flow distributor 6, a rotary dehumidifier 2, a total heat exchanger 3, a water storage tank 5, a solenoid valve group and a water-making mechanism 4.

[0033] The inlet 1a of the cyclone separator 1 is connected to the external air. The cyclone separator 1 separates the particulate impurities in the air and sends the relatively clean air into the rotary dehumidifier 2, providing a pure air intake source for the rotary dehumidifier 2 and improving the air intake efficiency.

[0034] The flow distributor 6 has an inlet 6a, a first air outlet 6b and a second air outlet 6c. The outlet 1b of the cyclone separator 1 is connected to the inlet 6a of the flow distributor 6 through a pipeline. The flow distributor 6 distributes the incoming air to the first air outlet 6b and the second air outlet 6c of the flow distributor 6 with different flow rates according to a given ratio.

[0035] The rotary dehumidifier 2 has a process air inlet 2a, a regeneration air inlet 2b, a process air outlet 2c and a regeneration air outlet 2d. The first air outlet 6b and the second air outlet 6c of the flow distributor 6 are respectively connected to the process air inlet 2a and the regeneration air inlet 2b of the rotary dehumidifier 2 through pipelines, and the process air outlet 2c of the rotary dehumidifier 2 is connected to the outside.

[0036] The processing air inlet 2a of the rotary dehumidifier 2 obtains air from the first air outlet 6b of the flow distributor 6, passes through the rotary dehumidifier 2, and is discharged from the processing air outlet 2c of the rotary dehumidifier 2. The regeneration air inlet 2b of the rotary dehumidifier 2 draws air from the second air outlet 6c of the flow distributor 6.

[0037] After passing through the rotary dehumidifier 2, high-humidity air flows out from the regeneration air outlet 2d of the rotary dehumidifier 2. The rotary dehumidifier 2 converts low-humidity air into high-humidity air, increases the water content in the air, and provides high-humidity air for the water production mechanism 4.

[0038] The total heat exchanger 3 has a cooling air inlet 3a, a wet air inlet 3b, a cooling air outlet 3c, and a wet air outlet 3d. The regeneration air outlet 2d of the rotary dehumidifier 2 is connected to the wet air inlet 3b of the total heat exchanger 3 through a pipeline, and the cooling air outlet 3c of the total heat exchanger 3 is connected to the outside; an adjustable speed wet air fan 3-1 is provided in front of the wet air outlet 3d in the total heat exchanger 3, and an adjustable speed cooling air fan 3-2 is provided in front of the cooling air outlet 3c in the total heat exchanger 3. A second temperature sensor 3-3 and a second humidity sensor 3-4 are provided at the cooling air inlet 3a of the total heat exchanger 3.

[0039] The total heat exchanger 3 utilizes the ambient atmosphere to precool the high-temperature wet air sent by the rotary dehumidifier 2 to the wet air inlet 3b of the total heat exchanger 3 to a reasonable temperature, thereby providing the water making mechanism 4 with a reasonable wet air inlet temperature and humidity.

[0040] The water making mechanism 4 includes a housing 4-9, an evaporator 4-1, a variable frequency compressor 4-2, a condenser 4-3, a water receiving tray 4-7, a water outlet pipe 4c and a fan 4-4;

The housing 4-9 has an air inlet 4a and an air outlet 4b. The air inlet 4a is provided with a first temperature sensor 4-5 and a first humidity sensor 4-8;

[0042] The evaporator 4-1, the variable frequency compressor 4-2, and the condenser 4-3 are connected in sequence to form a refrigeration circuit for refrigerant circulation. The water receiving tray 4-7 is arranged on the lower side of the evaporator 4-1 of the water making mechanism 4. One end of the water outlet pipe 4c is connected to the bottom of the water receiving tray 4-7, and the other end of the water outlet pipe 4c passes through the shell 4-9 and is connected to the water storage tank 5. The wet air outlet 3d of the total heat exchanger 3 is connected to the shell 4-9 through an air inlet 4a. The fan 4-4 first exchanges heat with the air flowing out of the wet air outlet 3d of the total heat exchanger 3 with the evaporator 4-1 of the water making mechanism 4, and then passes through the near side area of ​​the variable frequency compressor 4-2 and the condenser 4-3 and is discharged outside the water making mechanism 4. A third temperature sensor 4-6 is provided near the evaporator 4-1.

[0043] The liquid water produced by the water production mechanism 4 flows into the water inlet 5a of the water storage tank 5 from the water outlet pipe 4c of the water production mechanism 4, and the water can be drained by the principle of gravity. When the water storage tank 5 is full, it is discharged from the water outlet 5b of the water storage tank 5.

[0044] The solenoid valve group includes a first solenoid valve K1 and a second solenoid valve K2. The first solenoid valve K1 is arranged on the pipeline between the inlet 6a of the flow distributor 6 and the wet air inlet 3b of the heat exchanger 3. The second solenoid valve K2 is arranged on the pipeline between the regeneration air outlet 2d of the rotary dehumidifier 2 and the wet air inlet 3b of the heat exchanger 3. The first solenoid valve K1 and the second solenoid valve K2 have an interlocking mechanism.

[0045] A controller 7 is provided outside the novel wide-operating-condition composite water-making device. The controller 7 (a single-chip microcomputer is selected in this embodiment) receives signals from the first temperature sensor 4-5, the second temperature sensor 3-3, the third temperature sensor 4-6, the first humidity sensor 4-8, and the second humidity sensor 3-4. After calculation and comparison by the controller 7, the controller 7 controls the variable frequency compressor 4-2, the fan 4-4, the wet air fan 3-1, the cooling air fan 3-2, the first electromagnetic valve K1, the second electromagnetic valve K2 and the flow distributor 6, so that the water-making mechanism 4 is in the best water-making state according to the state of the environment, and more liquid water is produced with the lowest energy consumption ( Figure 1 The dashed lines in the figure indicate that the controller 7 is connected to various sensors, fans and variable frequency compressor 4-2. Figure 1 The arrows in the middle represent the direction of airflow).

[0046] The new wide-operating-condition composite water-making device has the following water-making modes:

[0047] a) Air passes through the cyclone separator 1, passes through the first electromagnetic valve K1 and the heat exchanger, the first electromagnetic valve K1 is opened, and water is produced through the water production mechanism 4, specifically:

[0048] When the water-making mechanism 4 is working, the variable frequency compressor 4-2 sucks the low-temperature and low-pressure refrigerant vapor produced by the evaporator 4-1 into the cylinder. After being compressed by the variable frequency compressor 4-2, when the pressure (temperature) increases to a level slightly greater than the pressure in the condenser 4-3, the high-pressure refrigerant vapor is discharged into the condenser 4-3. In the condenser 4-3, the high-temperature and high-pressure refrigerant vapor exchanges heat with the air (or water at room temperature) at a lower temperature and condenses into liquid refrigerant. At this time, the liquid refrigerant enters the evaporator 4-1 after being cooled (reduced in pressure), and then vaporizes after absorbing the heat of the cooled object in the evaporator 4-1. A cycle is completed in the water-making mechanism 4 through the four processes of compression, condensation, expansion, and evaporation. The evaporator 4-1, the variable frequency compressor 4-2, and the condenser 4-3 form a refrigeration circuit for refrigerant circulation. The high-humidity air passing through the evaporator 4-1 is condensed into condensed water. The water-making mechanism 4 is connected to the water storage tank 5, and the produced liquid water is discharged into the water storage tank 5.

The controller 7 controls the variable frequency compressor 4-2, the fan 4-4, the wet air fan 3-1, and the cooling air fan 3-2, opens the first electromagnetic valve K1, and closes the second electromagnetic valve K2, so that the temperature of the evaporator 4-1 is stabilized at about the dew point T1 set by the controller 7. The parameters provided by the first temperature sensor 4-5 and the first humidity sensor 4-8 determine the dew point T1 of the evaporator 4-1 controlled by the controller 7, and the fluctuation range is less than ±1°C.

The water making mechanism 4 is connected to the water storage tank 5, and the made liquid water is discharged into the water storage tank 5, completing the air flow and water making process;

[0051] The controller 7 receives the signals from the second temperature sensor 3-3 and the second humidity sensor 3-4, and the conclusion obtained by the controller 7 is that the dew point of water is T, 2℃≤T≤10℃. The controller 7 controls the variable frequency compressor 4-2, the fan 4-4, the wet air fan 3-1, the cooling air fan 3-2, and the flow distributor 6, closes the first electromagnetic valve K1, and opens the second electromagnetic valve K2, so that the temperature of the evaporator 4-1 is stabilized at about the dew point T2 set by the controller 7. The parameters provided by the first temperature sensor 4-5 and the first humidity sensor 4-8 determine the dew point T2 of the evaporator 4-1 controlled by the controller 7, and the fluctuation range is less than ±1℃. The evaporator 4-1 condenses on the surface, and water is produced in liquid form throughout the process.

[0052] c) Controller 7 receives signals from the first temperature sensor 4-5 and the first humidity sensor 4-8. The conclusion obtained by controller 7 is that the dew point of water is T, -10℃≤T≤2℃. Controller 7 controls variable frequency compressor 4-2, fan 4-4, wet air fan 3-1, cooling air fan 3-2, flow distributor 6, closes the first electromagnetic valve K1, and opens the second electromagnetic valve K2, so that the temperature of evaporator 4-1 is stabilized at about the dew point T3 set by controller 7. The parameters provided by the first temperature sensor 4-5 and the first humidity sensor 4-8 determine the dew point T3 of evaporator 4-1 controlled by controller 7, and the fluctuation range is less than ±1℃. Frost forms on the surface of evaporator 4-1, and water is produced by frosting and defrosting throughout the process.
