Description

TECHNICAL FIELD

[0001] The present application relates to a full-condition air water making unit, belonging to the technical field of air water making. BACKGROUND

[0002] With the global water resources becoming increasingly scarce, the demand for air water making equipment that can stably make clean drinking water from external fresh water in many regions is growing. At the same time, the relative humidity and dew point of some regions vary greatly at different time periods. In a high-humidity environment, although the water vapor is sufficient, water needs to be made quickly and in large flow. In a low-humidity environment, although the humidity is weak, there is still a demand for water making.

[0003] Most air water making units rely on cooling and dehumidification. Usually, a compressor and an evaporator are combined to condense and separate water by cooling the inlet air to below the dew point. For example, the common heat pump dehumidification type water making unit in the market is usually efficient in high-humidity conditions, but in dew point conditions below the freezing point (0 ℃), the evaporator is easy to frost and block, and needs to be defrosted periodically or equipped with an electric heating regeneration device. In addition, there are a few deep dehumidification systems that combine adsorption wheels and steam / electric heating regeneration, but their high-temperature regeneration energy consumption is too large, and the structure is complex and expensive, which is not conducive to large-scale promotion.

[0004] In traditional equipment, the simple cooling and dehumidification method is easy to freeze on the surface of the evaporator when the dew point is below 10 ℃ or the humidity is <7.0 g / kg, which leads to water production interruption or efficiency drop.

[0005] Therefore, a full-condition air water making unit is needed to continuously make water under the change of relative humidity and dew point at different time periods. The goal of stable, energy-saving and efficient water making throughout the year is achieved. SUMMARY

After these two heating cycles, the air is blown towards the regeneration side of the dehumidification rotor to remove moisture and increase humidity.

[0060] Preferably, when the humidity of the air is between 8g / kg and 15g / kg, and the water purification unit switches from the low humidity operation mode to the high humidity operation mode, the channel switching device does not operate, and the air continues to enter the low humidity air intake channel until the humidity of the air is greater than the preset humidity A.

[0064] Preferably, the channel switching device is specifically configured as an electric air valve.

[0065] The beneficial effects of this invention are:

[0066] (1) Through this invention, a high humidity operation mode and a low humidity operation mode are set. In the high humidity operation mode, the high humidity air inlet channel is opened, and the lower condenser circuit is controlled by the power-off control of the three-way valve. The air does not need to pass through too many parts to directly enter the water production channel for water production. The air has a high water content, and a large amount of humid air is quickly cooled to below the dew point, and a large amount of water is released in a short time. In the low humidity operation mode, the high humidity air inlet channel is closed, and the upper condenser regeneration heating circuit is controlled by the power-on control of the three-way valve. At the same time, in conjunction with the desorption and adsorption characteristics of the dehumidification wheel, the freezing point limit is broken to achieve low humidity water production. The high humidity operation mode or the low humidity operation mode is automatically switched according to the air inlet humidity. This invention can maintain the best energy efficiency and water production rate in different environments.

[0067] (2) Through this invention, the dehumidifying wheel can adsorb trace amounts of moisture that are difficult to condense in the evaporator, and with the help of medium-temperature regenerated air, the moisture is desorbed and transferred to the air before the evaporator, so that the evaporator can condense the moisture, breaking the limitation of the water vapor freezing point on the surface temperature of the evaporator, ensuring that water can still be produced at low dew points, and the inertia of the wheel smooths the airflow fluctuations, making water production more stable.

[0068] (3) By using the present invention, a three-way valve and upper / lower condensers are set up so that the heat generated by the heat pump system is directed to the upper condenser to provide heat for the desorption and regeneration of the dehumidification rotor when the humidity is low; and directed to the lower condenser when the humidity is high, and the low temperature air outlet of the evaporator is used to improve the condensation effect of the heat pump system and improve energy efficiency.

[0069] (4) Through this invention, the heat source of the regeneration section is taken from the waste heat released by the upper condenser of the heat pump system, which is recovered and used as the regeneration heating of the dehumidification rotor. No additional heating energy consumption is required, and the condensation waste heat that would otherwise be dissipated is efficiently reused, achieving the effect of energy saving.

[0070] (5) Through this invention, in order to prevent the unit frequency switching mode from causing large fluctuations in the system during the switching between high humidity operation mode and low humidity operation mode, the high humidity operation mode is executed when dry air with an absolute humidity content greater than 15 g / kg enters the water purification unit, and the low humidity operation mode is executed when dry air with an absolute humidity content less than 8 g / kg enters the water purification unit. Dry air with an absolute humidity content between g / kg and 15 g / kg is set to be in the control stagnation zone. When switching from high humidity operation mode to low humidity operation mode, the absolute humidity content of the air is first lower than 8 g / kg before switching the operation mode. When switching from low humidity operation mode to high humidity operation mode, the absolute humidity content of the air is first higher than 15 g / kg before switching the operation mode. In this way, the operating frequency of the water purification unit will not change suddenly and overcome the large fluctuations caused to the system. Attached Figure Description

Detailed Implementation

[0075] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific embodiments.

[0076] Example 1

[0077] like Figures 1-3 As shown, an air-to-water generator unit for all operating conditions includes a housing, a heat pump system, a dehumidification impeller, a water treatment system, and a control device.

[0078] The enclosure consists of a left section, a middle section, and a right section. Heat pump systems are installed in the left and right sections, a water treatment system in the middle section, and a dehumidifying impeller 2 in the right section. The heat pump system operates in two modes: a high-humidity mode and a low-humidity mode. The high-humidity mode is suitable for situations with high intake air humidity, while the low-humidity mode is suitable for situations with low intake air humidity. By switching between these two modes, water production can be achieved in different working environments. The dehumidifying impeller 2 overcomes the limitation of the cooling dehumidification freezing point during water production, enabling stable water production even in low dew point environments. The control device ensures the overall operation of the unit.

[0079] Reference Figure 1The partition 9 divides the right section of the housing into upper and lower sections. The upper section houses an evaporator 112 and a heat recovery heater 32, while the lower section houses an evaporator 2 122 and a lower condenser 2 144. The partition 9 has an opening near the middle of the housing, allowing airflow to pass through. An air inlet louver 81 is located above the partition 9 on the right edge of the right section, and an air outlet louver 82 is located below it. An electric damper 6 is located at the top right side of the right section, and a bypass ventilation duct 5 is located near the middle of the top of the right section. A cooling fan 124 is located at the top of the left section. The electric damper 6 is located at one end of the bypass ventilation duct 5, allowing the bypass ventilation duct to be opened by activating the electric damper 6.

[0080] An air filter 71 is installed at the top right edge of the right section of the housing. The air filter 71 is a rectangular frame with layered filter screens, positioned at the inlet of the heat recovery heater 32 to prevent dust. A blower 72 is installed at the bottom right edge of the right section of the housing to force the circulation of air throughout the entire system.

[0081] The enclosure also features an air inlet louver 81 on the top right edge of the right section. The control device can control the electric air valve 6, enabling airflow bypass in high humidity or airflow through the impeller and heat recovery in low humidity.

[0082] In this embodiment, the heat pump system is provided with two sets, including a first set of heat pump circuits and a second set of heat pump circuits.

[0083] The first heat pump circuit includes a compressor, evaporator, condenser, expansion valve, and three-way valve. The condenser includes an upper condenser and a lower condenser. In the first heat pump circuit, there is a compressor 111, an evaporator 112, an upper condenser 113, a lower condenser 114, an expansion valve 115, and a three-way valve 116. In the second heat pump system, there is a compressor 2 121, an evaporator 2 122, a condenser 2 123, a cooling fan 124, and an expansion valve 2 125.

[0084] Reference Figure 1 Compressor 111 is located on the lower right edge of the right section of the housing, compressor 112 is tilted and located on the upper left edge of the right section of the housing, upper condenser 113 is located in the upper middle part of the right section of the housing, and lower condenser 114 is located at the bottom of upper condenser 113. Three-way valve 116 has three connection ports: C, D, and E.

[0085] Compressor 111 draws in low-pressure steam, compresses it, and delivers high-pressure steam. The lower end of compressor 111 is connected to evaporator 112, and the other end is connected to port D of three-way valve 116. One end of evaporator 112 is connected to the outlet of expansion valve 115, and the other end is connected to compressor 111. Upper condenser 113 is located inside the upper left of the housing. Upper condenser 113 condenses high-temperature steam refrigerant and releases heat, providing a medium-temperature heat source for rotor regeneration and air heating. One end of upper condenser 113 is connected to port C of three-way valve 116, and the other end is connected to expansion valve 115. Lower condenser 114 is located below upper condenser 111 and installed in the same area. Lower condenser 114 can... Similarly, the high-temperature steam refrigerant is condensed and heat is released simultaneously. One end of the lower condenser 114 is connected to the expansion valve 115, and the other end is connected to port E of the three-way valve 116. The expansion valve 115 has a straight-through valve body structure and is installed above the evaporator 112. The expansion valve 115 can reduce pressure and throttle, and adjust the supply to the evaporator according to demand. One end of the expansion valve 115 is connected to the evaporator 112, and the other end is connected to the upper condenser 113 and the lower condenser 114. In this embodiment, the three-way valve 116 adopts an electromagnetic reversing valve body and is provided with ports C, D, and E. The control device is electrically connected to the three-way valve 116, and the control device can control the opening or closing of each joint of the three-way valve 16.

[0086] In this embodiment, the three-way valve 116 switches the refrigerant flow direction by gaining and losing power. When the three-way valve 116 is energized, its D port is connected to its C port, and the refrigerant flows to the upper condenser 113. When the three-way valve 116 is de-energized, its D port is connected to its E port, and the refrigerant flows to the lower condenser 114.

[0087] The second heat pump circuit includes compressor 121, evaporator 122, condenser 123, cooling fan 124, and expansion valve 125. In this embodiment, condenser 123 is located on the upper left section of the casing, cooling fan 124 is located on the top of the left section of the casing, evaporator 122 is located at the bottom of the right section of the casing, and cooling fan 124 is located on top of condenser 123.

[0088] The second heat pump circuit adopts a conventional single-stage refrigeration cycle. The connection method is as follows: one end of compressor 2 121 is connected to condenser 2 123, one end of condenser 2 123 is connected to expansion valve 2 125, one end of expansion valve 2 125 is connected to evaporator 2 122, and one end of evaporator 2 122 is connected to compressor 2 121.

[0089] Evaporator 112 and evaporator 2122 are connected in parallel in the air duct, and evaporator 112 and evaporator 2122 can start independently or in concert.

[0090] A dehumidifying impeller 2 is installed through the middle of the right section of the housing. The dehumidifying impeller 2 is divided into upper and lower parts. The upper part is the regeneration side, which is connected to the airflow flowing through the upper layer; the lower part is the adsorption side, which is connected to the airflow flowing through the lower layer. The dehumidifying impeller 2 can absorb trace amounts of moisture that have not been completely condensed from the air flowing through evaporator 112 and evaporator 222 from the adsorption side. The regeneration side is regenerated and desorbed by the upper condenser 113. The adsorption side can adsorb moisture from the air, and the regeneration side can desorb the moisture adsorbed by the dehumidifying impeller.

[0091] In this embodiment, a heat recovery system is provided in the right and middle sections of the housing. The heat recovery system includes a heat recovery cooler 31, a heat recovery heater 32, and a circulating water pump 33. The heat recovery cooler 31 is located in the middle of the right section of the housing, to the left of the dehumidification rotor 2. The heat recovery heater 32 is located to the right of the dehumidification rotor 2. The circulating water pump 33 is located at the top of the middle section of the housing.

[0092] The heat recovery cooler 31 extracts the sensible heat from the regeneration rotor's outlet air, reducing the dry-bulb temperature of the evaporator inlet air. Located on the inlet surfaces of evaporators 112 and 122, the heat recovery cooler 31 ensures a minimum dry-bulb temperature. The heat recovery heater 32 recovers the sensible heat from the regeneration rotor's outlet air and increases the inlet air temperature of the upper condenser, reducing the condensation heat demand of the heat pump system and thus reducing its operating power consumption. The circulating water pump 33 circulates water between the heat recovery cooler 31 and the heat recovery heater 32, and the control device controls its operation. The outlet air from the dehumidification rotor 2 enters evaporators 112 and 122 after passing through the heat recovery cooler 31. The heat recovery cooler 31 reduces the dry-bulb temperature of the inlet air, allowing more cooling energy to be used for latent heat condensation.

[0093] As another embodiment, the heat recovery system adopts a microchannel structure, specifically a two-phase phase change reflux structure. The self-gravity-driven microchannel is structurally composed of several parallel small channels or evaporation-condensation units, filled with a suitable working fluid. Its working principle is as follows: the hot end is located at the regeneration outlet of the dehumidification rotor 2 or other high-temperature side, and the cold end is located at the fresh air to be heated or the air inlet of the upper condenser 113. When the hot end absorbs the sensible heat of the regeneration outlet air, the working fluid vaporizes at the hot end and rises as vapor along the channel to the cold end. After the vapor condenses and releases heat at the cold end, the condensate returns to the hot end under the action of gravity or the reflux channel, completing a closed-loop cycle and realizing the transfer and recovery of heat from the hot end to the cold end. This type can achieve self-circulation (i.e., gravity / thermal siphon drive) by relying on height difference and phase change drive, or it can be used in conjunction with a circulating water pump or driven by a pump as needed to meet different heat exchange loads and installation conditions.

[0094] In this embodiment, the water treatment system is located at the bottom of the right section and the middle section of the tank. The water treatment system includes a water tank, a water pump 41, and a water storage tank 42. It also includes a high-level switch 421 for the water storage tank, a low-level switch 422 for the water storage tank, a water purifier 423, a water purification device 424, a high-level switch 431 for the water tank, and a low-level switch 432 for the water tank.

[0095] The water tank uses a stainless steel tray with a water collection pipe at the bottom. The tank collects condensate from evaporators 112, 122, and the heat recovery cooler 31. One end of the tank is connected to a water pump 41, which pumps water to a storage tank 42. The tank is equipped with a high-level switch 431 and a low-level switch 432. Both switches are float-type switches connected to a control device. They detect the water level in the tank. When the high-level switch 431 detects the tank is full, it activates the water pump 41 to pump water to the storage tank 42. When the low-level switch 432 detects a low water level, it shuts off the water pump 41.

[0096] In another embodiment, when the water generator enters the low humidity operation mode, the low humidity air cooling zone acts as a secondary water production zone; a secondary water tank is provided in the low humidity air cooling zone, and the secondary water tank is located below the heat recovery cooler 31; the condensate collected in the secondary water tank is transported to the delivery water tank through pipelines.

[0097] The water storage tank 42 is a stainless steel tank with a water outlet, capable of storing condensate before purification. A pipe at the bottom of the tank connects to the water purifier 423, allowing purified water to be supplied to the external water purification device 424. Inside the water storage tank 42 are a high-level switch 421 and a low-level switch 422, which detect the water level inside. These switches are connected to a control device to control the operation of water-related equipment, including the blower 72, heat recovery system, and heat pump system. When a high liquid level is triggered, the equipment stops operating.

[0098] In this embodiment, the control device includes sensors and a controller. The sensors can be temperature and humidity sensors or humidity sensors; in this embodiment, a temperature and humidity sensor is specifically used. The temperature and humidity sensor is located at the air inlet louver 81 and can monitor the air condition at the air inlet in real time. The controller is connected to each device and drives the start-up, shutdown, and operation mode control of equipment such as the three-way valve 116, bypass duct 5, electric valve 6, compressor one 111, compressor two 121, circulating water pump 33, water pump 41, and blower 72 based on the detection signals detected by the temperature and humidity sensor.

[0099] In this embodiment, the control device can activate a high humidity operation mode or a low humidity operation mode based on the detection signal detected by the temperature and humidity sensor.

[0100] The temperature and humidity sensors detect signals including the dew point and humidity of the incoming air. In high humidity operation mode, the water production capacity through air-to-water conversion is large; in low humidity operation mode, water production can be achieved under all operating conditions.

[0101] The controller is equipped with preset humidity levels to determine whether to operate in high-humidity or low-humidity mode. When the absolute moisture content of the air, as detected by the temperature and humidity sensors (e.g., dew point, humidity), is higher than the preset humidity level (A) for high-humidity mode, the controller operates in high-humidity mode. Conversely, when the absolute moisture content of the air, as detected by the temperature and humidity sensors, is lower than the preset humidity level (B) for low-humidity mode, the controller operates in low-humidity mode. It is particularly important to note that the preset humidity level can be adapted to the operating environment; different preset humidity levels can be set for different environments.

[0102] Here are some specific examples: preset humidity A is 15g / kg dry air, and preset humidity B is 8g / kg dry air.

[0103] When the air humidity is between 8g / kg and 15g / kg and the water purifier is switching from low humidity mode to high humidity mode, the channel switching device does not activate. Air continues to enter the low humidity air intake channel until the air humidity exceeds the preset humidity A. At this point, the channel switching device activates, the low humidity air intake channel closes, the high humidity air intake channel opens, air enters the high humidity air intake channel, and the water purifier enters the high humidity operation mode.

[0104] When the air humidity is between 8g / kg and 15g / kg and the water purifier is switching from high humidity mode to low humidity mode, the channel switching device does not activate. Air continues to enter the high humidity air intake channel until the air humidity is less than the preset humidity B. At this point, the channel switching device activates, the high humidity air intake channel closes, the low humidity air intake channel opens, air enters the low humidity air intake channel, and the water purifier enters the low humidity operation mode.

[0105] When the air humidity is between 8g / kg and 15g / kg and the water purification unit is started, the controller will issue an operating command to start either the high humidity operation mode or the low humidity operation mode.

[0106] In this embodiment, when the temperature and humidity sensor detects that the dew point and humidity of the incoming air meet the conditions of a high-humidity operating mode, the water purification unit...

[0107] In high humidity operation mode:

[0108] The controller controls the three-way valve 116 to de-energize, open the bypass ventilation duct 5, and send a start signal to the blower 72.

[0109] External air enters the right section of the housing through the air inlet louver 81 and passes through the air filter 71. The air filter 71 can trap dust and particles at the air inlet, ensuring that the subsequent devices are not affected by dust and particles, and improving water quality.

[0110] In high humidity operation mode, the electric air valve 6 is opened, allowing air to flow through the bypass ventilation duct 5, bypassing the heat recovery heater 32 and the regeneration side of the dehumidification impeller 2. The blower 72 operates, providing a stable airflow and driving the airflow into the enclosure. The incoming air sequentially enters evaporator 112 and evaporator 222, where the refrigerant vaporizes, absorbing the latent and sensible heat of the air and lowering the air temperature below the dew point. During this process, a large amount of water vapor condenses on the surface of the fins of evaporators 112 and 122, producing a large amount of condensate, which drips into the lower water tank. The treated air, after water purification, is discharged from the enclosure through the exhaust louvers 82 by the blower 72.

[0111] Cooling fan 124 is turned on. Cooling fan 124 is installed on top of condenser 2 123 to assist condenser 2 123 in heat dissipation and ensure stable circulation.

[0112] The condensate from evaporators 112 and 122 collects in a water tank. When the water level reaches the high-level switch 431, the water pump 41 starts and pumps water to the storage tank 42. The condensate in the storage tank is filtered by the purifier 423 and then sent to the water purification equipment 424 to ensure water quality. The high-level switch 421 disconnects the water circulation to prevent overflow.

[0113] In low humidity operation mode, the temperature and humidity sensor detects that the intake air humidity is lower than the preset humidity. The controller determines that it is operating in low humidity mode, energizes the three-way valve 116, closes the bypass ventilation duct 5, and starts the intake louver 81 and the blower 72.

[0114] Dry external air enters the filter 71 through the air inlet louvers 81, removing dust and protecting the heat recovery system and dehumidifying impeller 2. The airflow then enters the heat recovery heater 32, where the circulating water pump 33 sends the hydrothermal medium recovered by the heat recovery cooler 31 into the heater 32 to heat the air. The preheated air continues into the upper condenser 113 for further heating. The heated high-temperature airflow enters the regeneration side of the dehumidifying impeller 2, coming into contact with the trace amounts of moisture adsorbed on the impeller, causing it to desorb and enter the airflow, resulting in a significant increase in air humidity and a slight decrease in temperature. After the regenerated airflow merges with the initial treated airflow, the combined airflow flows through the heat recovery cooler 31. At this time, the circulating water pump 33 has returned the water medium released from the heater 32 to the cooler 31, where it absorbs the sensible heat of the airflow and evaporates, before being sent back to the heat recovery cooler 31 for condensation and circulation. The cooled airflow then passes sequentially through the evaporator 112 and evaporator 122, where the refrigerant absorbs the latent heat of the airflow, condensing and precipitating the desorbed water vapor and any remaining water vapor. The cooled airflow passes through the adsorption side of the dehumidifying impeller 2 again, capturing the trace amounts of moisture remaining after evaporation and slightly warming up. The blower 72 discharges the deeply dried air to the environment through the exhaust louvers 82; all condensate is collected in a water tank and pumped by the water pump 41 to the water storage tank 42, and then supplied for use after passing through the water purifier 423.

[0115] In low humidity operation mode, the dehumidification rotor 2 can adsorb trace amounts of moisture that are difficult to condense in the evaporator, and with the help of medium-temperature regenerated air, desorb the moisture and transfer it to the air before the evaporator, so that the evaporator can condense the moisture, breaking the limitation of the freezing point of water vapor on the surface of the evaporator, ensuring that water can still be produced even at low dew points. The rotor inertia smooths the airflow fluctuations, making water production more stable, and water can be produced even when the humidity of the incoming air is low.

[0116] In high-humidity operation mode, the high-humidity air is concentrated at evaporator 112 and evaporator 222 throughout the process, where it is deeply cooled and dehumidified. The bypass avoids wind resistance caused by extra loops, resulting in a large water production capacity and high efficiency. In low-humidity operation mode, the dry air is first heated, then desorbed, and then undergoes multiple stages of treatment including cooling, two-stage condensation, and rotary adsorption. This successfully overcomes the freezing point limitation and can stably produce condensate even in low dew point environments.

[0117] In low-humidity operation mode, the outlet air temperature on the regeneration side of the rotor is significantly higher than the fresh air temperature, resulting in a large temperature difference between the two, especially when the inlet air temperature is low. To further improve the energy efficiency and water production capacity of the heat pump system, a heat recovery system is installed. On one hand, this scheme places the heat recovery cooler 31 at the air inlet of the evaporator-112. The heat recovery cooler 31 absorbs the sensible heat in the outlet air of the rotor regeneration, thereby reducing the dry-bulb temperature of the inlet air of the evaporator-112. This allows the heat pump system to consume less sensible heat and convert more cooling energy into latent heat to facilitate dehumidification and water production. On the other hand, the heat recovery heater 32 is arranged at the air inlet of the upper condenser-113. It uses the heat absorbed by the heat recovery cooler 31 to heat the fresh air or regeneration inlet air, increasing the inlet air temperature of the upper condenser-113 and reducing its demand for regeneration heat source. The heat recovery cooler 31 and the heat recovery heater 32 are connected by pipelines, and driven by the circulating water pump 33, the internal working fluid circulates between them. When the exhaust air from the rotor regeneration passes through the heat recovery cooler 31, the working fluid absorbs heat from the air and reduces the inlet air temperature of the evaporator 112. The heated working fluid is then transported through pipelines to the heat recovery heater 32, where it exchanges heat with the inlet air and releases the heat into the air. After heat exchange, the working fluid flows back to the heat recovery cooler 31 for circulation. By configuring the heat recovery system, under the same input power conditions, more of the cooling capacity of the heat pump system can be used for latent heat condensation, significantly improving system energy efficiency and increasing water production capacity.
