Description

Technical Field

[0001] The utility model belongs to the technical field of air water production, and specifically relates to air water production equipment with self-adaptive high and low temperature environment dual operation modes. Background Art

[0002] The air-to-water equipment on the market uses fixed-frequency technology. Fixed-frequency devices have only two states: working and not working. There is no effective energy-saving method. At the same time, fixed-frequency technology cannot adjust the operating frequency according to the ambient temperature and humidity to achieve the water-making effect that adapts to the current environment. In addition, the air-to-water equipment uses a single refrigeration technology to achieve the purpose of condensation and water production. The operation of the air-to-water equipment requires an ambient temperature ≥12°C. When it is lower than 12°C, the condensation temperature difference is insufficient, and the water-making efficiency is extremely low or even impossible to produce water. The air-to-water equipment can produce water by adding an air heater (resistance type) to achieve ≥5°C, but the energy consumption is high and the water-making efficiency is low.

[0057] Working principle of this utility model:

[0058] The main control board has a built-in PID algorithm control program, and the operating logic of the water-making equipment is implemented and executed based on this PID algorithm control program.

[0059] The dual operation modes of the air-to-water equipment are normal operation mode and reverse operation mode. When the ambient temperature is between 15--50℃, the air-to-water equipment is set to normal operation mode. In normal operation mode, the air-to-water equipment inhales medium and high temperature hot air from the environment, and forms an effective temperature difference with the low temperature air on the surface of the first heat exchanger 45 of the air-to-water equipment, so as to achieve the purpose of condensation and water production. When the ambient temperature is between -5--15℃, the air-to-water equipment is set to reverse operation mode. In reverse operation mode, the air-to-water equipment inhales cold air from the environment, and the cold air is converted into hot air after passing through the first heat exchanger 45 and the external heat source exchanger 21, and forms an effective temperature difference with the low temperature air on the surface of the second heat exchanger 46, so as to achieve the purpose of condensation and water production.

[0060] 1. When the air-to-water device is in normal operation mode, the main control board will adaptively adjust the operation logic of the air-to-water device according to the ambient temperature.

[0061] ① When the ambient temperature is between 20-35℃, the PID algorithm control program built into the main control board is set, and the air water making equipment works in the normal operation mode. Under this ambient temperature condition, the temperature difference between the hot air and the first heat exchanger 45 of the equipment meets the requirements of condensation water making. Based on the temperature and humidity difference collected by the first sensor 29 and the second sensor 30, combined with the temperature difference ratio required for the maximum water production volume built into the main control board, the main control board automatically calculates the optimal operating power of the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12 through the built-in PID algorithm control program, and outputs the corresponding drive signal to control the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12 to operate in variable frequency.

[0062] In the normal operation mode, the second heat exchanger 46 completes the heat exchange of the refrigeration system, dissipates the heat generated by the refrigerant in the compression process of the variable frequency compressor 11 to the external environment, and changes the high-temperature and high-pressure liquid refrigerant output by the variable frequency compressor 11 into a medium-temperature and high-pressure liquid refrigerant. The variable frequency compressor 11 transmits the high-temperature and high-pressure liquid refrigerant to the four-way valve 25 through the first connecting pipe 26, and the main control board controls the four-way valve 25 to transmit the high-temperature and high-pressure liquid refrigerant to the second heat exchanger 46 through the fourth connecting pipe 23. The high-temperature and high-pressure gaseous refrigerant passes through the second heat exchanger 46 and becomes a medium-temperature and high-pressure liquid refrigerant.

[0063] The electronic expansion valve 12 is set according to the water production requirement of the air water production equipment, and the electronic expansion valve 12 converts the high-pressure liquid refrigerant output by the second heat exchanger 46 through the seventh connecting pipe 14 into a low-pressure gaseous refrigerant. On the one hand, the electronic expansion valve 12 limits the flow rate of the refrigerant to ensure that there is enough high pressure in the second heat exchanger 46, so that the liquid refrigerant entering the second heat exchanger 46 is converted into a gaseous refrigerant; at the same time, the electronic expansion valve 12 throttles the high-pressure liquid refrigerant and reduces the pressure, ensuring that the refrigerant has a suitable pressure when entering the first heat exchanger 45, which is conducive to the conversion of the low-pressure liquid refrigerant into a low-pressure gaseous refrigerant in the first heat exchanger 45.

[0064] The first heat exchanger 45 converts the low-pressure liquid refrigerant input from the sixth connecting pipe 24 into a low-pressure gaseous refrigerant. After the low-pressure liquid refrigerant output by the electronic expansion valve 12 enters the first heat exchanger 45, the internal channel of the first heat exchanger 45 suddenly expands, the refrigerant pressure is reduced, and it evaporates and gasifies rapidly, absorbing a large amount of heat, causing the surface temperature of the first heat exchanger 45 to drop sharply, causing a large temperature difference between the first heat exchanger 45 and the external environment, thereby causing the moisture in the circulating air to condense on the surface of the evaporator, and after being collected by the water collecting pan 15, the purpose of effective water production is achieved.

[0065] When the ambient temperature is between 20-35°C, the air-to-water equipment operates in normal mode. About 50%-70% of the cold energy generated by the first heat exchanger 45 is consumed in condensation water production, and the remaining cold energy is carried into the second heat exchanger 46 by the circulating air sucked in by the variable frequency air circulation fan 18, so as to achieve the purpose of cooling the second heat exchanger 46.

[0066] When the ambient temperature is between 20--35℃, the air-to-water equipment operates in normal mode, and the cooling capacity generated by the first heat exchanger 45 meets the water-making temperature difference requirement between the surface of the first heat exchanger 45 and the circulating air set by the air-to-water equipment. At the same time, the remaining cooling capacity carried by the circulating air after passing through the first heat exchanger 45 meets the heat dissipation requirement of the second heat exchanger 46. Therefore, when the ambient temperature is between 20--35℃, the alternating magnetic field induction heater electronic expansion valve 12 and the external heat source exchanger of the air-to-water equipment do not work, and the second heat exchanger 46 does not need auxiliary temperature compensation; the ultrasonic atomizer 22 does not work, and the second heat exchanger 46 does not need auxiliary cooling. Based on the temperature and humidity differences collected by the first sensor 29 and the second sensor 30, combined with the temperature difference ratio required for the maximum water production volume built into the main control board, the main control board automatically calculates the optimal operating power of the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12 through the built-in PID algorithm control program, and outputs corresponding drive signals to control the variable frequency operation of the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12, so as to achieve the purpose of effective water production and precise control of the operating power consumption of the air water production equipment.

[0067] ②When the ambient temperature is between 35--55℃, the PID algorithm control program built into the main control board is set, and the air water making equipment works in the normal operation mode. The operation mode of the relevant core components, the first heat exchanger 45, the external heat source exchanger 21, the second heat exchanger 46, the sixth connecting pipe 24, the seventh connecting pipe 14, the electronic expansion valve 12, the third connecting pipe 27, the second connecting pipe 13, the first connecting pipe 26, the variable frequency compressor 11, the alternating magnetic field induction heater electronic expansion valve 12, the four-way valve 25, the water collection tray 15, the variable frequency air circulation fan 18, the first sensor 29, the second sensor 30, the third sensor 28, and the fourth connecting pipe 23 are consistent with the operation mode described in the above normal operation mode ①.

[0068] When the ambient temperature reaches above 35°C, the air-water-making equipment operates in the normal operation mode. After the cooling capacity generated by the first heat exchanger 45 is consumed by water production, the remaining cooling capacity can no longer meet the heat dissipation and cooling requirements of the second heat exchanger 46. Moreover, for every 1°C increase in the ambient temperature on the basis of 35°C, the temperature of the second heat exchanger 46 itself will increase by 1-3°C, and the corresponding cooling effect of the first heat exchanger 45 will also decrease by 1-2°C, resulting in a decrease in the temperature difference between the surface of the first heat exchanger 45 and the circulating air by about 5-10°C, and theoretically the water production of the equipment is reduced by 40%-50%. When the ambient temperature reaches 45°C, the air-water-making equipment operates in the normal operation mode, and the temperature difference between the surface of the first heat exchanger 45 and the circulating air is attenuated by about 10-21°C, and theoretically the water production of the equipment is reduced by 90%-100%. When the ambient temperature reaches 50°C and above, the air-water-making equipment operates in the normal operation mode, and the surface temperature of the first heat exchanger 45 will not be lower than the ambient temperature, and theoretically the water production of the equipment is 0.

[0069] When the ambient temperature is 35°C or above, the air water making equipment operates in the normal operation mode. The difference from the above-mentioned normal operation mode ① operation logic is that the built-in PID algorithm control program of the main control board will start the ultrasonic atomization cooling function. The main control board starts the shunt pump 17 to extract the low-temperature condensed water flowing out of the water collection tray 15, and the low-temperature condensed water is sent to the ultrasonic atomizer 22 for atomization through the ninth connecting pipe 16. After the circulating air brought into the equipment by the variable frequency air circulation fan 18 meets the low-temperature atomized condensed water, the ambient air is cooled before the first heat exchanger 45, and the cooled external air and the residual cold after the first heat exchanger 45 makes water are sent to the second heat exchanger 46 to dissipate heat and cool the second heat exchanger 46. The main control board starts the ultrasonic atomization cooling function to cool the circulating air, ensure that the second heat exchanger 46 is fully cooled, ensure that the first heat exchanger 45 is fully cooled, and ensure that an effective water making temperature difference is formed between the surface of the first heat exchanger 45 and the ambient air, thereby ensuring the purpose of constant water making of the air water making equipment.

[0070] When the ambient temperature is 35°C or above, the air-to-water equipment operates in the normal operation mode and starts the ultrasonic atomization cooling function. The PID algorithm control program built into the main control board will calculate the temperature difference between the internal and external environments based on the temperature and humidity values ​​collected by the first sensor 29 and the second sensor 30. The PID algorithm control program adjusts the operating power of the variable frequency compressor 11 and the variable frequency air circulation fan 18 in real time according to the temperature difference, controls the amount of condensed water extracted by the shunt pump 17, and controls the amount of condensed water atomized by the ultrasonic atomizer 22. The PID algorithm control program accurately controls the balanced operation of the variable frequency compressor 11, the variable frequency air circulation fan 18, the shunt pump 17, and the ultrasonic atomizer 22 to ensure that the maximum effective temperature difference required for the real-time condensation and water production of the air-to-water equipment occurs between the circulating air and the surface of the evaporator, so as to achieve the purpose of effective water production and accurate control of the operating power consumption of the air-to-water equipment.

[0071] ③When the ambient temperature is between 15--20℃, the PID algorithm control program built into the main control board is set, and the air water making equipment works in the normal operation mode. The operation mode of the relevant core components, the first heat exchanger 45, the external heat source exchanger 21, the second heat exchanger 46, the sixth connecting pipe 24, the seventh connecting pipe 14, the electronic expansion valve 12, the third connecting pipe 27, the second connecting pipe 13, the first connecting pipe 26, the variable frequency compressor 11, the alternating magnetic field induction heater 20, the electronic expansion valve 12, the four-way valve 25, the water collection tray 15, the variable frequency air circulation fan 18, the first sensor 29, the second sensor 30, the third sensor 28, and the fourth connecting pipe 23 are consistent with the operation mode described in the above normal operation mode ①.

[0072] When the ambient temperature is between 15 and 20°C in the water collection tray, the air-to-water equipment operates in the normal operation mode. At this time, the temperature difference between the ambient air and the surface of the first heat exchanger 45 is small, and condensation water production cannot be achieved. Taking 20°C as the reference point, the temperature difference between the ambient air and the surface of the first heat exchanger 45 decays by 1°C for every 1°C drop in ambient temperature. The minimum surface temperature of the first heat exchanger 45 of the existing air condensation water production technology is 12°C. When the ambient temperature drops to 15°C, the existing air condensation water production technology will not be able to achieve effective water production. When the ambient temperature drops to 12°C or below, the ambient air temperature is close to or lower than the surface temperature of the first heat exchanger 45, and the existing air condensation water production technology cannot produce water.

[0073] When the ambient temperature is 15--20℃ in the water collection tray, the air water making equipment works in normal operation mode. The difference from the above operation logic is that the built-in PID algorithm control program of the main control board will start the temperature difference constant compensation function, such as Figure 4The main control board controls the operating power of the variable frequency compressor 11 and the variable frequency air circulation fan 18, and then controls the circulating air intake, so as to suppress the surface temperature of the first heat exchanger 45 to a low temperature floating state between 1--5°C, so as to maintain a constant and effective air condensation water production temperature difference between the ambient air and the surface of the first heat exchanger 45, and ensure that the air water production equipment produces water at a constant ambient temperature of 15--20°C, so as to achieve the purpose of effective water production and accurate control of the operating power consumption of the air water production equipment.

[0074] 2. When the air-to-water equipment is in reverse operation mode, the main control board will adaptively adjust the operation logic of the air-to-water equipment according to the ambient temperature.

[0075] When the ambient temperature is lower than 15°C, the existing air condensation water making technology or the air water making equipment in the normal operation mode cannot achieve an effective water making temperature difference between the ambient air and the first heat exchanger 45. When the ambient temperature is lower than 15°C, the PID algorithm control program built into the main control board of the air water making equipment is set, and the air water making equipment works in the reverse operation mode.

[0076] ① When the ambient temperature is between 5--15℃, the PID algorithm control program built into the main control board operates in the reverse operation mode according to the settings. The air water making equipment is adjusted from the normal operation mode of "inhaling hot air and mixing with the cold air on the surface of the first heat exchanger 45 to make water" to the reverse operation mode of "inhaling cold air and mixing with the hot air on the surface of the first heat exchanger 45, and then mixing with the cold air on the surface of the second heat exchanger 46 to make water".

[0077] When the air-to-water equipment operates in the reverse operation mode, the main control board 32 controls the four-way valve 25 to switch the high-pressure gaseous refrigerant output from the fourth connecting pipe 23 to the third connecting pipe 27, and switches the low-pressure gaseous refrigerant input from the third connecting pipe 27 to the fourth connecting pipe 23. The evaporator in the normal operation mode becomes the condenser in the reverse operation mode, and the function of the condenser is to complete the heat exchange of the refrigeration system of the air-to-water equipment. The condenser in the normal operation mode becomes the evaporator in the reverse operation mode. The heat generated in the process of compressing the refrigerant by the variable frequency compressor 11 is carried to the second heat exchanger 46 by the ambient air sucked in by the variable frequency air circulation fan, and the air condensation water production is realized by mixing with the low-temperature air on the surface of the second heat exchanger 46.

[0078] When the air-to-water device operates in the reverse operation mode, the high-temperature and high-pressure liquid refrigerant output by the variable frequency compressor 11 enters the four-way valve 25 through the first connecting pipe 26. The main control board controls the four-way valve 25 according to the PID algorithm control program setting, and transports the high-temperature and high-pressure liquid refrigerant to the first heat exchanger 45 through the third connecting pipe 27; the high-temperature and high-pressure liquid refrigerant releases heat in the first heat exchanger 45 and is converted into low-temperature and high-pressure liquid refrigerant; the low-temperature and high-pressure liquid refrigerant is transported to the electronic expansion valve 12 through the seventh connecting pipe 14. The electronic expansion valve 12 limits the flow rate of the refrigerant on the one hand, ensuring that there is enough high pressure in the first heat exchanger 45, so as to promote the refrigerant to enter the first heat exchanger 4 5 is converted into gaseous refrigerant, and at the same time, the electronic expansion valve 12 throttles the high-pressure liquid refrigerant and reduces its pressure, ensuring that the refrigerant has a suitable pressure when entering the second heat exchanger 46, which is conducive to the conversion of the low-pressure liquid refrigerant into a low-pressure gaseous refrigerant in the second heat exchanger 46; the high-pressure liquid refrigerant becomes a low-pressure liquid refrigerant after passing through the electronic expansion valve 12; the low-pressure liquid refrigerant enters the second heat exchanger 46 through the seventh connecting pipe 14, and the low-pressure liquid refrigerant is converted into a low-pressure gaseous refrigerant in the second heat exchanger 46; the low-pressure gaseous refrigerant flows to the four-way valve 25 through the fourth connecting pipe 23, and then flows into the variable frequency compressor 11 through the low-pressure second connecting pipe 13. Since the internal passage of the second heat exchanger 46 suddenly expands, the low-pressure liquid refrigerant absorbs a large amount of heat when it is converted into a low-pressure gaseous refrigerant in the second heat exchanger 46, causing the surface temperature of the second heat exchanger 46 to drop sharply. There is a large temperature difference between the hot air inhaled by the variable frequency air circulation fan 18 through the first heat exchanger 45 and the surface of the second heat exchanger 46, causing the moisture in the hot air to condense on the surface of the second heat exchanger 46, and then collected by the water collection tray 15 to achieve the purpose of effective water production and water use.

[0079] When the ambient temperature is between 5--15℃, the PID algorithm control program built into the main control board operates in reverse operation mode according to the settings. The PID algorithm control program accurately controls the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12 to operate in a balanced manner, ensuring the maximum effective temperature difference required for the air water making equipment to condense and make water in real time between the circulating air and the evaporator surface, so as to achieve the purpose of effective water making and accurate control of the operating power consumption of the air water making equipment.

[0080] ②When the ambient temperature is between -5 and -5℃, the PID algorithm control program built into the main control board is set, and the air water making equipment works in the reverse operation mode. The operation mode of the relevant core components, the first heat exchanger 45, the ultrasonic atomizer 22, the second heat exchanger 46, the sixth connecting pipe 24, the seventh connecting pipe 14, the electronic expansion valve 12, the third connecting pipe 27, the second connecting pipe 13, the first connecting pipe 26, the variable frequency compressor 11, the alternating magnetic field induction heater electronic expansion valve 12, the water collection tray 15, the variable frequency air circulation fan 18, the first sensor 29, the second sensor 30, the third sensor 28, and the fourth connecting pipe 23 are consistent with the operation mode described in the above reverse operation mode ①.

[0081] Since the external ambient air temperature is too low, the surface temperature of the second heat exchanger 46 reaches 0°C or below in a very short time; since the cold air in the external environment absorbs a large amount of heat generated by the first heat exchanger 45, the circulating air flowing into the second heat exchanger 46 cannot form an effective water-making temperature difference with the surface of the second heat exchanger 46, causing the air-to-water equipment to lose its water-making capacity.

[0082] When the ambient temperature is between -5 and -5℃, the built-in PID algorithm control program in the main control board of the air-to-water equipment starts the temperature difference compensation function of the external heat source. Figure 4 As shown, the main control board has a built-in PID algorithm control program combined with an alternating magnetic field induction heater to provide an external heat source temperature difference compensation solution for air water making equipment in ultra-low temperature environments. When the first sensor 29 detects that the ambient temperature is less than 5°C, the third sensor 28 detects that the air temperature in the external heat source exchanger 21 is less than 15°C, and the second sensor 30 detects that the surface temperature of the second heat exchanger 46 is less than 0°C, the main control board's built-in PID algorithm control program starts the alternating magnetic field induction heater electronic expansion valve 12 according to the calculation results and the equipment program settings, and transfers heat energy from the heat transfer medium to the external heat source exchanger 21 through the fifth connecting pipe 19, providing temperature compensation for the circulating air between the first heat exchanger 45 and the second heat exchanger 46, so as to form a constant temperature difference between the ambient air flowing to the second heat exchanger 46 and the surface of the second heat exchanger 46, thereby achieving the purpose of effective water production.

[0083] When the ambient temperature is between -5 and -5°C, the built-in PID algorithm control program of the main control board of the air water making equipment starts the external heat source temperature difference compensation function. The main control board controls the first sensor 29, the second sensor 30, and the third sensor 28 in real time to monitor the ambient air temperature, the internal circulating air temperature of the external heat source exchanger, and the surface temperature of the second heat exchanger 46. After the built-in PID algorithm control program of the main control board accurately calculates, the built-in PID algorithm control program of the main control board adjusts the operating power of the variable frequency compressor 11, the variable frequency air circulation fan 18, and the electronic expansion valve 12 in real time, controls the air intake entering the air water making equipment, and ensures a constant water making temperature difference between the circulating air and the surface of the second heat exchanger 46, so as to achieve the purpose of effective water making and accurate control of the operating power consumption of the air water making equipment.
