Description

Technical Field

[0001] The present invention relates to the field of air conditioning and cloud control, and in particular to a noodle drying heat pump system based on cloud technology application. Background Art

[0002] Heat pump drying technology uses the reverse Carnot principle to absorb heat from the surrounding environment and transfer it to the heated object to achieve drying of the items. Due to its high energy efficiency and low pollution to the environment, it is widely used in the drying of industrial and agricultural products. In particular, in recent years, heat pump drying using heat recovery technology has achieved more obvious energy savings and has been widely used, becoming a trend to replace traditional coal-fired boiler drying and other means.

[0003] However, due to the high processability of drying technology, it is necessary to monitor and adjust the drying parameters of industrial and agricultural products, such as noodles, in real time throughout the drying process. Currently, users perform on-site manual monitoring, which mainly relies on experience. Since the manual experience required for monitoring drying is high, whether or not there is experience directly affects the drying quality of industrial and agricultural products such as noodles. There are defects such as unstable drying quality, and the inability to adapt to large-scale, high-quality and stable drying of noodles with certain differences in raw materials.

[0004] At the same time, in the process of drying industrial and agricultural products such as noodles, there is often a need to adjust the temperature of the use space, but the temperature adjustment methods generally adopted are often not energy-saving, such as independently adopting air-conditioning system cooling and other methods. Therefore, it is urgent and necessary to find a technical solution to achieve efficient drying of industrial and agricultural products such as noodles, efficiently adjust the temperature of the use space, and recycle the energy consumed by the drying heat pump system to achieve the purpose of energy saving. Summary of the invention

[0005] In order to solve the above problems, the present invention uses cloud computing technology and hot and cold water provided by at least one water-cooled chiller to analyze and support the drying data of noodles placed in at least one drying room through big data analysis of the cloud server. Users use operating devices to monitor. With the support of the cloud server, users do not need much experience to achieve the purpose of high-quality and stable drying of large quantities of noodles with certain differences in raw materials. At the same time, it also achieves efficient control of the drying + cooling and drying modes of the drying heat pump system, and the purpose of fully recycling the consumed energy.

[0006] To achieve the above-mentioned purpose, the present invention provides a noodle drying heat pump system based on cloud technology application, comprising a water-cooled chiller, a hot water storage, a cold water storage, a terminal, a drying room and a cloud server; the cold water generated by the operation of the water-cooled chiller is stored in the cold water storage, and the hot water generated by the operation of the water-cooled chiller is stored in the hot water storage; the hot water in the hot water storage is sent to the high-temperature surface cooler in the drying room to increase the air flowing into the drying room to dry the noodles, and a heat recovery surface cooler and an auxiliary cooler are also provided, the heat recovery surface cooler is located in the drying room, and the auxiliary cooler and the hot water storage The cold water in the cold water storage is used to reduce the temperature of the use space at the terminal, or directly flows into the heat recovery cooler for air dehumidification and heat recovery; the working data of at least one of the water-cooled chillers, hot water storage, cold water storage, terminal, and at least one of the drying rooms are transmitted to the cloud server through wired or wireless means, and the cloud server sends the data to the operating device after analysis and processing. The user can remotely query the operating data through the operating device, and realize the drying + cooling, or drying mode control of the drying heat pump system by controlling the operating device.

[0007] Furthermore, the heat recovery surface cooler includes a first heat recovery surface cooler and a second heat recovery surface cooler, the first heat recovery surface cooler is arranged near the air outlet in the drying room air duct, and the second heat recovery surface cooler is arranged near the air inlet in the drying room air duct; a heat exchange core is also provided, and the outside air is first cooled by the second heat recovery heat exchanger, and then flows through the heat exchange core, absorbs the heat of the high-humidity and hot air for drying noodles that cross-flows through the heat exchange core, and then passes through the high-temperature surface cooler for heating for drying noodles. The high-humidity and hot air for drying noodles that releases heat through the heat exchange core flows out of the heat exchange core, continues to flow through the second heat recovery heat exchanger to release heat, and is finally circulated and discharged to the outside atmosphere.

[0008] The heat recovery surface cooler is set up in stages and used in conjunction with the heat exchange core to fully recover energy and achieve energy-saving operation.

[0009] Furthermore, the water-cooled chiller is a water-cooled screw chiller; and two water-cooled screw chillers are provided.

[0010] Two water-cooled screw chillers are installed to flexibly adjust the required amount of heat and cold, achieving energy-saving operation.

[0011] Furthermore, the cold water storage device stores cold water at a temperature of 6 to 12°C.

[0012] The cold water temperature is set at 6 to 12°C, which can effectively reduce the temperature of the space in use, or dehumidify the drying air and recover heat.

[0013] Furthermore, the hot water storage device stores hot water at a temperature of 60-90°C.

[0014] The hot water temperature is set between 60 and 90°C, which can effectively adjust the temperature of the drying air.

[0015] Furthermore, the auxiliary cooler is a cooling tower or a finned radiator.

[0016] The above settings can achieve reasonable auxiliary heat dissipation and ensure the reasonable and balanced operation of the noodle drying heat pump system.

[0017] Furthermore, there are two drying rooms.

[0018] 2 settings can achieve the effect of drying noodles with certain differences in drying raw materials or batch drying.

[0019] Furthermore, the air temperature for drying the noodles is 40-70° C., and the relative humidity is 40-65%.

[0020] The above-mentioned air temperature parameters can achieve the effect of high-quality drying of noodles.

[0021] The present invention also provides a method for drying noodles, using the above-mentioned drying heat pump system based on cloud technology application to dry the noodles, and the drying steps are:

[0022] S1: The noodles are placed in the drying area of ​​the drying room, and the sealing door of the drying area is closed;

[0023] S2: starting the water-cooled chiller on-site or remotely through the operating device, circulates and heats the hot water stored in the hot water reservoir to increase the temperature of the hot water, and circulates and lowers the temperature of the cold water stored in the cold water reservoir;

[0024] S3: When the temperature of the hot water in the hot water storage and the cold water in the cold water storage reaches the set value, the drying room is started to operate, and the drying mode is operated for at least 15 minutes according to the default setting, and then the operation mode is adjusted according to the use needs, specifically:

[0025] When the drying mode is continued, the cold water in the cold water storage directly flows into the second heat recovery cooler in the drying room, reduces the temperature and humidity of the air passing through the surface of the second heat recovery cooler, and then becomes low-temperature dry air and continues to cross-flow through the heat exchange core, absorbs the heat of the high-humidity hot air of the dried noodles that cross-flows through the heat exchange core, and then flows through the surface of the high-temperature cooler to exchange heat with the hot water that flows from the hot water storage into the heat exchange tube of the high-temperature cooler. After the temperature is increased, it flows into the drying area of ​​the drying room to dry the noodles. The high-humidity hot air that has been dried cross-flows through the heat exchange core and the second heat recovery cooler, and is finally circulated and discharged to the outside atmosphere or used in a closed loop.

[0026] When the operation is set to the drying + cooling mode, the cold water stored in the cold water storage is first sent to the terminal, and after lowering the air temperature in the use space, it circulates into the cold water storage. At the same time, the hot water stored in the hot water storage flows into the heat exchange tube of the high-temperature surface cooler, and exchanges heat with the air that absorbs the heat of the high-humidity and hot air of the dried noodles that crosses the heat exchange core. After the temperature rises, it flows into the drying area of ​​the drying room to dry the items, and finally circulates and discharges to the outside atmosphere or is used in a closed manner;

[0027] During use,

[0028] In the drying + cooling mode, when the load required by the terminal is low and the temperature of the cold water stored in the cold water storage is lower than 6°C and lasts for more than 30 minutes, it will automatically switch to the drying mode;

[0029] In drying + cooling or drying mode, when the hot water temperature in the hot water storage is higher than 90°C and lasts for more than 30 minutes, the auxiliary cooler is started to operate, and the auxiliary cooler is used to dissipate heat with the outside air to reduce the hot water temperature;

[0030] S4: After the noodles are dried, the operating device is used to control the drying room to stop working, and the water-cooled chiller continues to operate until the hot water in the hot water storage and the cold water in the cold water storage reach the set value, and then stops;

[0031] S5: The working parameters for drying noodles are completed and stored in the cloud server. The big data is analyzed and sorted by the cloud server and automatically classified. The historical data is used for comparison during the next operation for intelligent adjustment to improve the quality and efficiency of drying noodles in the drying room.

[0032] This technical solution, through cloud computing technology, uses hot and cold water provided by at least one water-cooled chiller to analyze and support the drying data of noodles placed in at least one drying room through big data analysis and support of cloud servers, and users use operating devices to monitor, thereby at least achieving:

[0033] 1. It can achieve high-quality and stable drying effect for large quantities of noodles with certain differences in raw materials without much experience;

[0034] 2. According to the needs, realize the efficient operation control of drying + cooling and drying modes of drying heat pump system, and fully recycle the consumed energy. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] Preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to illustrate the technical solutions of the present invention in detail.

[0038] like Figure 1 As shown, the present invention provides a noodle drying heat pump system based on cloud technology application, including a terminal 1, a cold water storage 2, a water-cooled chiller 3, a cloud server 4, a hot water storage 5 and a drying room 7.

[0039] The cold water generated by the operation of the water-cooled chiller 3 is stored in the cold water storage tank 2, and the hot water generated by the operation of the water-cooled chiller 3 is stored in the hot water storage tank 5; the hot water in the hot water storage tank 5 is sent to the high-temperature surface cooler in the drying room 7, and is used to increase the air flowing into the drying room 7 to dry the noodles. A heat recovery surface cooler and an auxiliary cooler 9 are also provided. The heat recovery surface cooler is arranged in the drying room 7. The auxiliary cooler 9 is connected to the pipeline of the hot water storage tank 5, and is used for cooling the stored hot water, that is, the excess heat of the hot water is dissipated into the atmosphere through the auxiliary cooler 9 to maintain the normal operation of the water-cooled chiller 3.

[0040] The cold water in the cold water storage device 2 is used at the terminal 1 to lower the temperature of the use space, or directly flows into the heat recovery cooler for air dehumidification and heat recovery; the working data of at least one terminal 1, the cold water storage device 2, the water-cooled chiller 3, the hot water storage device 5, and at least one drying room 7 are transmitted to the cloud server 4 by wired or wireless means, and the cloud server 4 sends the data to the operating device 6 after analysis and processing. The user 8 can remotely query the operating data through the operating device 6, and realize the drying + cooling, or drying mode control of the drying air-conditioning system by controlling the operating device 6.

[0041] In order to meet the special process requirements of drying noodles with certain differences in drying raw materials or the purpose of drying noodles in batches, preferably, there are two drying rooms 7, namely the first drying room 71 and the second drying room 72.

[0042] The setting of the two drying rooms 7 can meet the different drying process requirements of the noodles A7131 and the noodles B7231 with certain differences, or dry the noodles in batches, thereby improving the drying efficiency.

[0043] The differences between A7131 and B7231 noodles are mainly reflected in the differences in flour raw materials, flour moisture content and noodle specifications, which lead to different drying process requirements.

[0044] In order to achieve the purpose of flexibly adjusting the required amount of cold and heat and energy-saving operation, preferably, the water-cooled chiller 3 is divided into two units, namely the first water-cooled chiller 31 and the second water-cooled chiller 32. The water-cooled chiller is a water-cooled screw chiller. The setting of the water-cooled screw chiller can ensure that the unit capacity can be flexibly adjusted and the operation is more energy-saving.

[0045] The installation of two water-cooled screw chillers can flexibly adjust the number of units in operation according to the required cooling and heating loads. At the same time, the water-cooled screw chillers themselves have the ability to adjust their own capacity, so they can achieve further precise energy regulation, thereby achieving the purpose of energy-saving operation.

[0046] In addition to the water-cooled screw chiller, other types of products such as water-cooled scroll chillers can also be used, and the specific number of units required can be set as needed.

[0047] In addition to the two drying rooms 7 and the two water-cooled chillers 3, more drying rooms 7 and water-cooled chillers 3 may be provided as required.

[0048] In this embodiment, the terminal 1 is configured as three terminals, namely the first terminal 11, the second terminal 12 and the third terminal 13. Of course, a single terminal, double terminals or more terminals may also be configured.

[0049] Besides being provided in a single unit, the cold water storage 2 and the hot water storage 5 can also be provided in multiple units to meet the requirements of different usage occasions.

[0050] In order to fully recover the energy of the drying room 7 and achieve the purpose of energy-saving operation, preferably, the heat recovery surface cooler includes the first heat recovery surface cooler A715, the second heat recovery surface cooler A716, and the first heat recovery surface cooler B725 and the second heat recovery surface cooler B726.

[0051] The first heat recovery condenser A715 and the second heat recovery condenser A716 are arranged in the first drying room 71, and the first heat recovery condenser B725 and the second heat recovery condenser B726 are arranged in the second drying room 72.

[0052] The first heat recovery surface cooler A715 is arranged near the air outlet in the air duct of the first drying room 71, close to the first fan 717; the second heat recovery surface cooler A716 is arranged in the air duct of the first drying room 71, near the first air inlet 718.

[0053] The first heat recovery surface cooler B725 is arranged near the air outlet in the air duct of the second drying room 72, close to the second fan 727; the second heat recovery surface cooler B726 is arranged in the air duct of the second drying room 72, near the second air inlet 728.

[0054] A first heat exchange core 714 and a second heat exchange core 724 are also provided; the first heat exchange core 714 is placed at a cross-flow position in the middle of the air duct of the first drying room 71, and the second heat exchange core 724 is placed at a cross-flow position in the middle of the air duct of the second drying room 72.

[0055] The high-temperature cooler is divided into a first high-temperature cooler 712 and a second high-temperature cooler 722. The first high-temperature cooler 712 is arranged in the air duct of the first drying room 71, with the air inlet side facing the first heat exchange core 714, and the air outlet side facing the first drying area 713; the second high-temperature cooler 722 is arranged in the air duct of the second drying room 72, with the air inlet side facing the second heat exchange core 724, and the air outlet side facing the second drying area 723.

[0056] The first drying room 71 works as follows:

[0057] The first fan 717 drives the outside air to flow from the first air inlet 718 into the air duct of the first drying room 71, passes through the second heat recovery condenser A716, crosses into the first heat exchange core 714, absorbs the heat of the high-humidity hot air that crosses through the first heat exchange core 714 and is used to dry the noodles A7131, then flows through the first high-temperature condenser 712, enters the first drying area 713, dries the noodles A7131 placed in the first drying area 713, crosses through the first heat exchange core 714, enters the first heat recovery condenser A715, continues to release heat to the first heat recovery condenser A715, and is finally circulated to the outside atmosphere through the first fan 717.

[0058] The second drying room 72 works as follows:

[0059] The second fan 727 drives the outside air to flow from the second air inlet 728 into the air duct of the second drying room 72, passes through the first heat recovery condenser B725, crosses into the second heat exchange core 724, absorbs the heat of the high-humidity hot air of the dried noodles B7231 that crosses through the second heat exchange core 724, flows into the second high-temperature condenser 722, enters the second drying area 723, dries the noodles B7231 placed in the second drying area 723, crosses through the second heat exchange core 724, enters the first heat recovery condenser B725, continues to release heat to the first heat recovery condenser B725, and is finally circulated to the outside atmosphere through the second fan 727.

[0060] The drying room 7 adopts a heat exchange core + heat recovery device design, which can fully recover energy during the drying process and achieve the purpose of energy-saving operation.

[0061] In order to effectively reduce the temperature of the use space, or to dehumidify the drying air and recover the heat, preferably, the temperature of the cold water stored in the cold water storage 2 is 6-12°C.

[0062] It can be flexibly adjusted according to usage needs. When the load that needs to lower the temperature of the use space is large, the cold water temperature can be set to 6°C. When the load of the use space is not large, the cold water temperature can be appropriately increased. For example, suitable temperatures such as 8, 10, 12°C can be used for cooling or dehumidification of drying air to ensure energy-saving operation of the water-cooled chiller 3.

[0063] In order to effectively adjust the temperature of the drying air, preferably, the hot water stored in the hot water storage 5 has a temperature of 60-90°C.

[0064] The hot water temperature is controlled at 60-90°C, and through the heat exchange of the first high-temperature condenser 712 and the second high-temperature condenser 722, the temperature of the drying air is effectively heated to a reasonable range, thereby drying the noodles with high efficiency and quality.

[0065] In order to ensure that the excess heat of the hot water stored in the hot water storage 5 is dissipated and to ensure the stable operation of the water-cooled chiller 3, preferably, the auxiliary cooler 9 is a cooling tower or a finned radiator.

[0066] The heat dissipation principle of the cooling tower is the same as that of the existing cooling tower and will not be introduced in detail. The heat dissipation of the finned radiator is to set a fan on one side of the heat exchanger. The fan forces the outside air to flow through the surface of the finned radiator and exchange heat with the hot water flowing into the heat exchange tube of the finned radiator to achieve the purpose of dissipating part of the heat.

[0067] The inlet of the auxiliary cooler 9 can be connected to the outlet of the hot water storage 5 through the third hot water pump 55, and the outlet of the auxiliary cooler 9 is connected to the inlet of the third hot water pump 55 through a pipeline to form a heat exchange circulation loop. Hot water is pumped into the auxiliary cooler 9 through the third hot water pump 55 to dissipate heat with the outside air.

[0068] In order to achieve the purpose of high-quality dried noodles, preferably, the air temperature used to dry noodles A7131 and noodles B7231 is 40-70° C. and the relative humidity is 40-65%.

[0069] The drying of A7131 and B7231 noodles is generally divided into four stages according to the process requirements: cold air shaping, low temperature drying, heating drying and cooling and heat dissipation. The specific parameter requirements are:

[0070] 1. Cold air shaping and drying stage:

[0071] The drying air temperature is controlled at 40-45°C, and the relative humidity is controlled at 50-60%; the time is 15% of the total drying time, and the air is forced to flow through the first fan 717 and the second fan 727 respectively, so that the noodles A7131 set in the first drying room 71 and the noodles B7231 in the second drying room 72 are initially fixed to remove moisture from the surface of the noodles.

[0072] 2. Low temperature drying stage:

[0073] The drying air temperature is 45-50°C, the relative humidity is controlled at 60-65%, and the drying time is 25% of the total drying time. The moisture of noodles A7131 and noodles B7231 is mainly diffused internally. The first fan 717 and the second fan 727 continue to operate to circulate the air.

[0074] 3. Heating and drying stage:

[0075] The drying temperature is 65-70°C, the relative humidity is controlled at 60-65%, and the drying time is 30% of the total drying time.

[0076] 4. Cooling and heat dissipation stage:

[0077] The drying temperature is 40-45°C, and the relative humidity is controlled at 40-50%. The drying time is 30% of the total drying time until the noodles A7131 and B7231 are completely dried.

[0078] The temperature, humidity parameters and time control in different drying stages can be further determined and accurately selected according to the specific process requirements of noodles A7131 and noodles B7231.

[0079] The operating mode of the present invention works as follows:

[0080] 1. Drying + cooling operation mode

[0081] The high-pressure and high-temperature gaseous refrigerant compressed by the first screw compressor 311 of the first water-cooled chiller 31 flows into the first shell and tube condenser 313, and undergoes condensation heat exchange with the circulating water that is pumped into the first shell and tube condenser 313 by the fifth hot water pump 57 and stored in the hot water storage tank 5. After the circulating water absorbs heat and its temperature rises to become hot water, it flows out of the first shell and tube condenser 313 and circulates into the hot water storage tank 5 for storage; the condensed refrigerant becomes high-pressure liquid and flows out of the first shell and tube condenser 313. After being throttled by the first thermal expansion valve 315, it flows into the first shell and tube evaporator 314, and undergoes evaporation heat exchange with the cold water that is pumped into the first shell and tube evaporator 314 by the first chilled water pump 22 and stored in the cold water storage tank 2. After its temperature drops to become cold water, it flows out of the first shell and tube evaporator 314 and circulates into the cold water storage tank 2 for storage.

[0082] Similarly, the high-pressure and high-temperature gaseous refrigerant compressed by the second screw compressor 321 of the second water-cooled chiller 32 flows into the second shell and tube condenser 323, and undergoes condensation heat exchange with the circulating water that is pumped into the second shell and tube condenser 323 by the fourth hot water pump 56 and stored in the hot water storage tank 5. After the circulating water absorbs heat and its temperature rises to become hot water, it flows out of the second shell and tube condenser 323 and circulates into the hot water storage tank 5 for storage; the condensed refrigerant becomes a high-pressure liquid and flows out of the second shell and tube condenser 323. After being throttled by the second thermal expansion valve 325, it flows into the second shell and tube evaporator 324, and undergoes evaporation heat exchange with the cold water that is pumped into the second shell and tube evaporator 324 by the second chilled water pump 23 and stored in the cold water storage tank 2. After its temperature drops to become cold water, it flows out of the second shell and tube evaporator 324 and circulates into the cold water storage tank 2 for storage.

[0083] To achieve remote monitoring, a fifth transmitting controller 3121 is provided in the first electrical control box 312 on the first water-cooled chiller 31 , and a sixth transmitting controller 3221 is provided in the second electrical control box 322 on the second water-cooled chiller 32 .

[0084] The fifth transmitting controller 3121 is used to collect the operating parameters of the first water-cooled chiller 31, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to control the operation of the first water-cooled chiller 31 and adjust relevant operating parameters;

[0085] The 6th transmitting controller 3221 is used to collect the operating parameters of the 2nd water-cooled chiller 32, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to control the operation of the 2nd water-cooled chiller 32 and adjust relevant operating parameters.

[0086] The cold water stored in the cold water storage tank 2 is pumped into the cold water through the third chilled water pump 25, and flows into the heat exchange tubes of the first end 11, the second end 12 and the third end 13 heat exchangers respectively from the opened first solenoid valve 26, so as to reduce the temperature of the use space and realize the adjustment of the refrigeration operation mode of the use space. At this time, the second solenoid valve 27 is closed.

[0087] After the cold water absorbs the heat of the use space and its temperature rises, it flows out of the heat exchange pipes of the first end 11, the second end 12 and the third end 13 heat exchangers respectively, and circulates into the cold water storage 2 from the first one-way valve 28 and the opened third solenoid valve 29 in sequence.

[0088] At the same time, in order to realize remote monitoring, a first transmitting controller 111 is set at the first terminal 11, a second transmitting controller 121 is set at the second terminal 12, and a third transmitting controller 131 is set at the third terminal 13.

[0089] The first transmitting controller 111 is used to collect the operating parameters of the first terminal 11, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to control the operation of the first terminal 11 and adjust relevant operating parameters;

[0090] The second transmitting controller 121 is used to collect the operating parameters of the second terminal 12, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to control the operation of the second terminal 12 and adjust relevant operating parameters;

[0092] While lowering the temperature of the use space, the hot water stored in the hot water storage 5 is divided into two paths for high-temperature drying in the first drying room 71 and the second drying room 72, specifically:

[0093] The first route is pumped into the heat exchange tube of the first high-temperature condenser 712 of the first drying room 71 by the first hot water pump 52, and exchanges heat with the air flowing through the outer surface of the first high-temperature condenser 712. The air temperature increases after absorbing heat and is used to dry the noodles A7131 in the first drying room 71. After the hot water temperature is reduced after the heat release is completed, it circulates back to the hot water storage 5 for storage;

[0094] The second route is pumped into the heat exchange tube of the second high-temperature condenser 722 of the second drying room 72 by the second hot water pump 53, and exchanges heat with the air flowing through the outer surface of the second high-temperature condenser 722. The temperature of the air that absorbs heat increases and is used for drying the noodles B7231 in the second drying room 72. After the temperature of the hot water is reduced after the heat release is completed, it circulates back to the hot water storage 5 for storage.

[0095] 2. Drying operation mode

[0096] According to the above drying+cooling operation mode, the cold water produced by the first water-cooled chiller 31 and the second water-cooled chiller 32 is stored in the cold water storage tank 2 , and the hot water produced by the first water-cooled chiller 31 and the second water-cooled chiller 32 is stored in the hot water storage tank 5 .

[0097] First, the cold water stored in the cold water storage 2 is pumped into the cold water through the third chilled water pump 25, and flows into the drying room 7 from the opened second electromagnetic valve 27, and is divided into two paths, specifically at the following locations:

[0098] The first route flows into the heat exchange tube of the second heat recovery condenser A716 of the first drying room 71, absorbs the heat of the air flowing through the surface of the second heat recovery condenser A716, and after the air is cooled and dehumidified, it becomes low-temperature dry air. The cold water temperature rises and flows out of the heat exchange tube of the second heat recovery condenser A716, and continues to flow into the heat exchange tube of the first heat recovery condenser A715, and exchanges heat again with the high-humidity hot air after drying that has recovered the heat energy of the first heat exchange core 714, and flows out of the heat exchange tube of the first heat recovery condenser A715 after absorbing the heat.

[0099] The second route flows into the heat exchange tube of the second heat recovery condenser B726 of the second drying room 72, absorbs the heat of the air flowing through the surface of the second heat recovery condenser B726, and after the air is cooled and dehumidified, it becomes low-temperature dry air. The cold water temperature rises and flows out of the heat exchange tube of the second heat recovery condenser B726, and continues to flow into the heat exchange tube of the first heat recovery condenser B725, and exchanges heat again with the high-humidity hot air after drying that has recovered the heat energy through the second heat exchange core 724, and flows out of the heat exchange tube of the first heat recovery condenser B725 after absorbing the heat.

[0100] The cold water flowing out of the heat exchange pipes of the first heat recovery condenser A715 and the first heat recovery condenser B725 is collected and circulated into the cold water storage tank 2 through the second one-way valve 7151.

[0101] At this time, the first solenoid valve 26 and the third solenoid valve 29 are closed.

[0102] The low-temperature dry air that has completed cooling and dehumidification is heated by the first high-temperature condenser 712 and the second high-temperature condenser 722 respectively, and then becomes high-temperature dry air and is used to dry noodles A 7131 and noodles B 7231. The specific heating is the same as the hot water heating in the above-mentioned drying + cooling operation mode, and will not be repeated here.

[0103] Similarly, in order to realize remote monitoring of the drying + cooling operation mode, in addition to the corresponding transmission controllers set on the terminal 1 and the cold water cooling unit 3, the 4th transmission controller 21 is set on the cold water storage tank 2, the 7th transmission controller 51 is set on the hot water storage tank 5, the 8th transmission controller 711 is set on the 1st drying room 71, and the 9th transmission controller 721 is set on the 2nd drying room 72.

[0104] The fourth transmitting controller 21 is used to collect the operating parameters of the cold water storage 2, and output the operating parameters to the cloud server 4 by wired or wireless means, and receive the control instructions issued by the cloud server 4 to dynamically control the operating parameters of the cold water storage 2 such as the cold water temperature, storage volume, and circulation volume;

[0105] The seventh transmitting controller 51 is used to collect the operating parameters of the hot water storage device 5, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to dynamically control the operating parameters of the hot water storage device 5, such as the hot water temperature, storage volume, and circulation volume;

[0106] The eighth transmitting controller 711 is used to collect the operating parameters of the first drying room 71, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive the control instructions issued by the cloud server 4 to control the operation of the first drying room 71 and adjust the relevant operating parameters;

[0107] The 9th transmitting controller 721 is used to collect the operating parameters of the second drying room 72, and output the operating parameters to the cloud server 4 via wired or wireless means, and receive control instructions issued by the cloud server 4 to control the operation of the second drying room 72 and adjust relevant operating parameters.

[0108] The operating parameters received by the cloud server 4 are sent to the operating device 6 in a wired or wireless manner after being analyzed and processed by the cloud server 4. The operating device 6 includes a computer 61 and a mobile device 62. The user 8 can remotely query the operating data of the noodle drying air-conditioning system equipment by using the computer 61 or the mobile device 62, and send control instructions to the cloud server 4 by controlling the operating computer 61 or the mobile device 62. After processing, the cloud server 4 transmits the instructions to the corresponding related transmitting controller to control the operation of the related equipment to realize the drying + cooling, or drying mode control of the drying air-conditioning system.

[0109] Monitoring by computer 61 or mobile device 62 can be carried out by downloading APP, logging into APP interface for monitoring, etc. At the same time, the cloud server 4 background can also set up an expert background. With the help of big data analysis of cloud server 4 and the help of experts, user 8 can realize efficient monitoring of the drying air-conditioning system in a fool-proof manner anywhere, without the need for additional experience or expertise, which greatly simplifies the conventional restrictions on professional maintenance of air-conditioning and drying systems.

[0110] The air used for drying the noodles in this embodiment can adopt an open drying cycle, that is, it comes directly from the outside atmosphere, or a closed drying cycle, that is, the air after the noodles are dried is circulated in a closed manner for drying.

[0111] The cold water reservoir 2 can be replenished with water through the cold water replenishment solenoid valve 24 , while the hot water reservoir 5 can be replenished with water through the hot water replenishment solenoid valve 54 .

[0112] In addition, the present invention also provides a drying heat pump system based on cloud technology application using the above embodiment to dry noodles. The specific drying steps are as follows:

[0113] Step S1: placing the noodles in the drying area of ​​the drying room 7, and closing the sealing door of the drying area;

[0114] Step S2: by operating the device 6, the customer 8 starts the water-cooled chiller 3 on-site or remotely, circulates to reduce the temperature of the cold water stored in the cold water storage 2, and circulates to heat the hot water stored in the hot water storage 5, raising the temperature of the hot water;

[0115] Step S3: When the cold water temperature of the cold water storage 2 and the hot water of the hot water storage 5 reach the set value, the drying room 7 is started to operate, and the drying mode is operated for at least 15 minutes according to the default setting, and then the operation mode is adjusted according to the use needs, specifically:

[0116] When the drying mode is continued, the cold water in the cold water storage 2 directly flows into the second heat recovery cooler of the drying room 7, reduces the temperature and humidity of the air on the surface of the second heat recovery cooler, and then becomes low-temperature dry air and continues to cross-flow through the heat exchange core. After absorbing the heat of the high-humidity hot air of the dried noodles that cross-flows through the heat exchange core, it flows through the surface of the high-temperature cooler and exchanges heat with the hot water that flows from the hot water storage 5 into the heat exchange pipe of the high-temperature cooler. After the temperature rises, it flows into the drying area of ​​the drying room 7 to dry the noodles. After the dried high-humidity hot air cross-flows through the heat exchange core and the second heat recovery cooler, it is finally circulated and discharged to the outside atmosphere or used in a closed loop.

[0117] When the operation is set to drying + cooling mode, the cold water stored in the cold water storage 2 is first sent to the terminal 1, and after lowering the air temperature in the use space, it circulates into the cold water storage 2. At the same time, the hot water stored in the hot water storage 5 flows into the heat exchange tube of the high-temperature surface cooler, and exchanges heat with the air that absorbs the heat of the high-humidity hot air of the dried noodles that crosses the heat exchange core. After the temperature rises, it flows into the drying area of ​​the drying room 7 to dry the items, and finally circulates and discharges to the outside atmosphere or is used in a closed manner;

[0118] During use,

[0119] In the drying + cooling mode, when the load required by the terminal 1 is low and the temperature of the cold water stored in the cold water storage is lower than 6°C and lasts for more than 30 minutes, it will automatically switch to the drying mode;

[0120] In drying + cooling, or drying mode, when the hot water temperature in the hot water storage 5 is higher than 90°C and lasts for more than 30 minutes, the auxiliary cooler 9 is started to operate, and the auxiliary cooler 9 is used to dissipate heat with the outside air to reduce the hot water temperature;

[0121] S4: After the noodles are dried, the operating device 6 is used to control the drying room 7 to stop working, and the water-cooled chiller 3 continues to operate until the cold water temperature of the cold water reservoir 2 and the hot water in the hot water reservoir 5 reach the set value, and then stops;

[0122] S5: The working parameters for drying noodles are completed and stored in the cloud server 4. The big data of the cloud server 4 is analyzed and sorted, and automatically classified. The historical data is used for comparison during the next operation for intelligent adjustment to improve the quality and efficiency of drying noodles in the drying room 7.

[0123] The specific operation modes can be found in the description of the corresponding operation modes above, which will not be repeated here.

[0124] In the drying + cooling and drying operation mode switching, such as in the transition season, when the terminal 1 does not need too much cooling capacity, the first solenoid valve 26 and the second solenoid valve 27 can be opened at the same time, and the third solenoid valve 29 can be closed; the mixed cold water flows to the heat recovery surface cooler of the drying room 7 to ensure that the excess cooling capacity is used for dehumidification and heat recovery of the air in the drying room 7 while meeting the temperature regulation of the use space. The first solenoid valve 26 and the second solenoid valve 27 can be replaced by a proportional regulating valve, and the flow of cold water flowing out of the proportional regulating valve can be adjusted according to different needs to meet the use needs. At the same time, the number of water-cooled chillers 3 that are turned on and off, as well as the precise adjustment of the capacity of a single unit, can be coordinated to balance the use of cold and heat.

[0125] Since the present invention adopts the means of heat recovery surface cooler + heat exchange core and auxiliary cooler 9, the balance of cold and heat provided by the water-cooled chiller 3 can be adjusted at any time according to the usage through the big data analysis and processing of the cloud server 4, thereby ensuring the reliability of the use of the water-cooled chiller 3. The balance of cold and heat is adjusted as follows:

[0126] The cold water storage 2 stores the coldness of cold water, which is used by the terminal 1 or the heat recovery condenser; the hot water storage 5 stores the heat of hot water, which is used by the high-temperature condenser + auxiliary cooler 9.

[0127] In summer operation: when the heat required by the drying room 7 is greater than the cooling capacity of the space in use, only the terminal 1 refrigeration cycle is turned on, and the cold water stored in the cold water storage 2 will drop lower and lower. When it reaches the set point and continues to drop, the operation mode will be switched, and heat will be supplemented through the heat recovery cooler to balance the hot and cold energy on both sides, thereby achieving the purpose of dual temperature control;

[0128] When the heat dissipation of the high-temperature surface cooler on the drying room 7 side is less than the cooling load of the use space at the end 1, the temperature of the hot water stored in the hot water storage 5 will increase. When it reaches the set value, the auxiliary cooler 9 will be started to dissipate heat while the high-temperature surface cooler is in use, so as to balance the cold and hot energy on both sides, thereby achieving the purpose of dual temperature control.

[0129] When there is no cooling in other seasons, the drying mode is started, and the heat recovery cooler is fully operated to recover heat for evaporation and absorption of the water-cooling chiller 1, and the hot water stored in the hot water storage 5 is used in the drying room 7 according to the set constant water outlet temperature. The temperature of the cold water stored in the cold water storage 2 does not need to be controlled.

[0130] Due to heat loss, the recovered heat will be less than the supplied heat, but through the operation of the water-cooled chiller 1, 1 part of heat will be absorbed and 1.3 parts of heat will be generated. The excess 0.3 is generated by the heat dissipation of the compressor power, and the extra 0.3 is used to make up for the heat loss. Compared with other heating methods, the water-cooled chiller 1 can provide more heat for use, so that the entire noodle drying heat pump system can operate in a completely closed loop without the need for additional auxiliary heat.

[0131] The noodle drying heat pump system can be used not only for drying noodles, but also for drying other items, such as grains, red dates and other industrial and agricultural products.

[0132] The above is only one embodiment, and those skilled in the art may make various modifications and changes to the present invention. Therefore, the present invention covers various modifications and changes that fall within the scope of the appended claims and their equivalents.
