[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] See also Figure 1 The present invention provides a technical solution: a highly efficient and energy-saving dehumidification unit, including a direct-cooling compression condensing section 100 and a multi-connected distributed air processing section 200. The direct-cooling compression condensing section 100 is arranged outdoors, and the multi-connected distributed air processing section 200 is arranged indoors. The direct-cooling compression condensing section 100 is used to control cooling and heat dissipation, and the multi-connected distributed air processing section 200 is used to process the air so that the treated air is stable within the cleanliness requirements and the air supply temperature range.

[0041] The direct cooling compression condensing section 100 and the multi-connected distributed air treatment section 200 are respectively connected by pipelines with a flow equalizer 10 and a flow equalizer 2 17, so that the direct cooling compression condensing section 100 and the multi-connected distributed air treatment section 200 form a circulation loop, and the flow equalizer 10 and the flow equalizer 2 17 are used to evenly distribute the refrigerant flow to various parts of the room.

[0042] The direct cooling compression condensing section 100 includes a compressor 1, an oil separator 2, a gas-liquid separator 3, a four-way valve 4, a direct cooling condenser 5, a direct evaporation distributor 6, a liquid storage device 7, a drying filter 8 and an electronic expansion valve 9 connected by pipelines. The four-way valve 4 includes a valve body and a D tube, an E tube, an S tube and a C tube arranged on the valve body. The D tube is connected to the oil separator 2, the E tube is connected to the multi-connected distributed air treatment section 200, the S tube is connected to the gas-liquid separator 3, and the C tube is connected to the direct evaporation distributor 6. The four-way valve 4 is used to achieve the switching of the cooling and heating functions by changing the flow direction of the refrigerant. The condenser 5 and the direct evaporation distributor 6 are connected in series in the direct cooling compression condensing section 100, the liquid reservoir 7, the drying filter 8 and the electronic expansion valve 9 are connected in series in the direct cooling compression condensing section 100, a one-way valve 1 is arranged on the connecting pipeline of the direct cooling condenser 5, the liquid reservoir 7 and the electronic expansion valve 9, a pipeline 18 is connected on the connecting pipeline of the direct cooling condenser 5, the liquid reservoir 7 and the electronic expansion valve 9, a group of one-way valves 2 with opposite flow directions are arranged on the pipeline 18, the pipeline 18 and the pipeline connected with the drying filter 8 and the electronic expansion valve 9 are connected with the pipeline of the flow equalizer 10.

[0043] A second drying filter and a heating wire are also connected between the gas-liquid separator 3 and the oil separator 2 through a pipeline. The second drying filter and the heating wire are used when the unit is heated.

[0044] The multi-connected distributed air treatment section 200 includes several groups of air handling machines, which are connected in parallel. The air handling machines include a heat exchanger 13, an electronic expansion valve 2 15 and a drying filter 3 16 connected by pipelines. A blower 12 and a jet air duct 11 are arranged on one side of the heat exchanger 13, and an air filter 14 is arranged on the other side of the heat exchanger 13. The jet air duct 11, the blower 12, the heat exchanger 13 and the air filter 14 are correspondingly positioned and arranged in sequence. The heat exchanger 13 is connected to a flow equalizer 10 pipeline. The heat exchanger 13 is connected to a one-way valve 3. The one-way valve 3 is connected in parallel with the electronic expansion valve 2 15 and the drying filter 3 16. The one-way valve 3 and the drying filter 3 16 are connected to the flow equalizer 2 17. The flow equalizer 2 17 is connected to the E pipe of the four-way valve 4, thereby forming a circulation loop. The heat exchanger 13 is preferably a high-efficiency finned heat exchanger.

[0045] In this embodiment, when the unit is refrigerating, the compressor 1 of the direct cooling compression condensing section 100 is running, and the exhaust end of the compressor 1 discharges high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the direct evaporation uniform distributor 6 for primary cooling and uniform distribution, and then enters the direct cooling condenser 5 for secondary condensation. The high-temperature and high-pressure gas becomes a high-temperature and high-pressure liquid. The high-temperature and high-pressure liquid is throttled by the electronic expansion valve 9 and becomes a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid is distributed by the flow distributor 10 and enters the multi-connected distributed air treatment section 200 in the room. After absorbing heat through multiple heat exchangers 13, it is gathered into a low-temperature and low-pressure gas and returns to the compressor 1. The compressor 1 is compressed to a high-temperature and high-pressure gas. This cycle is repeated to realize the refrigeration cycle of the unit.

[0046] When the unit is dehumidifying, when the blower 12 starts to supply air, the air is first filtered and purified by the air filter 14, and then cooled by the heat exchanger 13. At this time, the moisture in the air condenses into water droplets and is discharged. Finally, the cooled and dehumidified air enters the room through the jet air duct 11 for circulation to achieve indoor dehumidification.

[0047] When the unit is heating, the four-way valve 4 switches the refrigerant flow direction, so that the heat exchanger 13 in the air handling unit in the cooling mode is transformed into a condenser, and the outdoor direct cooling condenser 5 is transformed into a heat exchanger. The operating principle at this time is similar to the operating principle during cooling, and both are existing technologies and will not be elaborated here.

[0048] In this embodiment, by adding a direct cooling condenser 5 and a direct evaporation distributor 6 to the direct cooling compression condensing section 100, the compressed refrigerant can be evenly distributed, the condensation efficiency is improved, and the condensation temperature during the operation of the unit is reduced, thereby achieving a high efficiency and energy-saving effect; at the same time, by setting a multi-connected distributed air treatment section 200, the flexibility of indoor modular layout can be improved, and the more complex indoor air duct layout project can be solved. It is suitable for cooling and heat exchange in a larger space area, and the cooling capacity of the unit is improved, which is beneficial to reduce the energy consumption during the operation of the unit.

[0049] Embodiment 2:

[0050] See also Figure 2~Figure 13On the basis of the first embodiment, the jet air duct 11 includes a main air duct 111, the position of the main air duct 111 corresponds to the position of the air blower 12, auxiliary air ducts 112 are arranged on both sides of the main air duct 111, the auxiliary air duct 112 is connected to the auxiliary air duct 112 pipeline of the adjacent jet air duct 11, a motor 113 is fixedly connected to the top of the auxiliary air duct 112, and a valve plate 114 is fixedly connected to the output end of the motor 113. The cross-section of the valve plate 114 is T-shaped, and the surface of the valve plate 114 is divided into a smooth surface and a convex surface. The valve plate 114 is used to control the opening and closing of the auxiliary air duct 112 and to lead the wind in the main air duct 111 to the auxiliary air duct 112 when the auxiliary air duct 112 is opened. The valve plate 114 is connected to the bearing of the auxiliary air duct 112, and the auxiliary air duct 112 is fixedly connected to the air blower 2 115.

[0051] It should be noted that all the jet air ducts 11 can only guide the air volume on one side, and cannot guide on both sides.

[0052] See also Figure 5 In actual operation, the initial state is that the T-shaped long side of the valve plate 114 is parallel to the main air duct 111, and the protrusion directions of the two sets of valve plates 114 are consistent, that is, the auxiliary air duct 112 is in a closed state, and the second blower 115 is not started. At this time, the wind of the main air duct 111 cannot be introduced into the adjacent main air duct 111 through the auxiliary air duct 112;

[0053] See also Figure 6~Figure 11 When the wind from the main air duct 111 needs to be introduced into the adjacent main air duct 111 through the auxiliary air duct 112, the motors 113 on the two connected auxiliary air ducts 112 are both started. The motors 113 on the auxiliary air ducts 112 are started to drive the valve plate 114 to rotate, so that the smooth surface of the valve plate 114 faces the air inlet of the main air duct 111 and is inclined toward the air inlet of the main air duct 111. Figure 6 As shown, the direction of the valve plate 114 is opposite to the wind direction of the main air duct 111, which can lead a large amount of wind from the main air duct 111 to the auxiliary air duct 112. At the same time, the inclined valve plate 114 is not conducive to the introduction of wind from the auxiliary air duct 112 to the main air duct 111;

[0054] When the T-shaped smooth surface of the valve plate 114 faces the air inlet of the main air duct 111 but is inclined toward the air outlet of the main air duct 111, as shown in FIG. Figure 7 As shown, the inclination direction of the valve plate 114 is the same as the wind direction of the main air duct 111, which is not conducive to leading the wind to the auxiliary air duct 112. At the same time, the raised portion on the valve plate 114 increases the resistance of the wind entering the main air duct 111 from the auxiliary air duct 112, so that the air volume entering the auxiliary air duct 112 is reduced;

[0055] When the T-shaped smooth surface of the valve plate 114 faces the air outlet of the main air duct 111 but is inclined toward the air inlet of the main air duct 111, as shown in FIG. Figure 8As shown, although the direction of the valve plate 114 is opposite to the wind direction of the main air duct 111 at this time, and the wind can be introduced from the main air duct 111 to the auxiliary air duct 112, the raised portion of the valve plate 114 will increase the resistance of the wind entering the auxiliary air duct 112, thereby reducing the amount of wind introduced into the auxiliary air duct 112 by the valve plate 114, and at the same time, it is not conducive to the introduced wind entering the main air duct 111 from the auxiliary air duct 112, thereby adjusting the amount of wind introduced into the auxiliary air duct 112;

[0056] When the T-shaped smooth surface of the valve plate 114 faces the air outlet of the main air duct 111 and is inclined toward the air outlet of the main air duct 111, as shown in FIG. Fig. 9 As shown, the inclination direction of the valve plate 114 is the same as the wind direction of the main air duct 111. At this time, the direction of the valve plate 114 is not only not conducive to leading the wind to the auxiliary air duct 112, but the convex surface of the valve plate 114 also increases the resistance of the wind entering the auxiliary air duct 112, thereby further reducing the amount of air introduced into the auxiliary air duct 112 by the valve plate 114. However, at this time, the smooth side of the valve plate 114 can facilitate the wind from the auxiliary air duct 112 to enter the main air duct 111. Therefore, the motor 113 on the two adjacent groups of auxiliary air ducts 112 can make the valve plate 114 in different states, and the wind can be led from the main air duct 111 to the adjacent main air duct 111. In order to further improve the effect of leading the air volume, the blower 115 on the auxiliary air duct 112 for leading the air is started. Fig.10 As shown, the wind in the main air duct 111 can be introduced into the adjacent main air duct 111 to the maximum extent. Fig.11 As shown, the amount of air introduced into the adjacent main air duct 111 can be reduced.

[0057] A high-efficiency and energy-saving dehumidifier unit also includes an intelligent control system, which includes a program setting module, a collection and analysis module, and an early warning control module. The program setting module is used to set and display the indoor temperature. The program setting module includes a setting unit and a display unit. The setting unit is used to set the indoor temperature to be maintained, and the display unit is used to display the actual indoor temperature.

[0058] The acquisition and analysis module is used to collect the temperature of each area and the operation status of the equipment and perform analysis and processing. The acquisition and analysis module includes an acquisition unit, a time unit, a counting unit and an analysis unit. The acquisition unit is electrically connected to multiple groups of temperature sensors 19, the temperature sensors 19 are used to monitor the temperature in the workshop, the time unit is used to record the operation time of the equipment in the workshop, the counting unit is used to record the number of areas with high temperature in the workshop, and the analysis unit is used to perform comparative analysis based on the indoor temperature;

[0059] The early warning control module is used to control the air volume allocation and alarm prompts of abnormal situations. The early warning control module includes a control unit and an early warning unit. The control unit is electrically connected to the motor 113 and the blower 2 115 in the multi-connected distributed air treatment section 200. The control unit is used to adjust the air volume inside the jet air duct 11, and the early warning unit is used to issue an alarm prompt in abnormal situations.

[0060] It should be noted that the interior of the workshop is divided into several corresponding areas according to the number of air handling units. The number of temperature sensors 19 is at least the same as the number of air handling units, and they are distributed inside several areas to monitor the temperature inside the corresponding air handling unit action areas.

[0061] How the intelligent control system works:

[0062] Step 1: Set the temperature standard value T in the program setting module. When the temperature in the area is lower than the temperature standard value T, there is no need to start the cooling process.

[0063] Step 2: The collection unit collects the temperature of each area in the workshop, and the time unit records the operating time of the equipment in each area of ​​the workshop, and feeds it back to the analysis unit for comparative analysis. The early warning control module then intelligently adjusts the air volume and early warning prompts.

[0064] Specifically, the collection unit collects the initial temperature and actual temperature monitored by the temperature sensor 19 in each area of ​​the workshop, the time unit records the total time of the internal equipment in each area of ​​the workshop, and the actual temperature of each area in the room is recorded as , the initial temperature of each area in the room is recorded as ,The total operation time of equipment in each area of ​​the room is recorded as , i is a positive integer from 1 to x, x is the number of air handling units in the workshop, i corresponds to the number of air handling units in the workshop and the serial number of the area. Since the operation of the equipment in the workshop is the main reason for the increase in the ambient temperature, the analysis unit is set with a regional temperature theoretical value for controlling the start of the dehumidifier unit according to the initial temperature of each area and the number and time of equipment operation in each area. The regional temperature theoretical value is recorded as , , , is the total temperature rise coefficient of the area, k is the number of devices running in the area, n is the total number of devices in the area, and m is the temperature rise per unit time when the equipment in the area is operating normally.

[0065] S1: Control the dehumidification unit to start;

[0066] Initial , the dehumidifier unit is started at the beginning, which proves that the internal ambient temperature of this area in the workshop is high at this time. The dehumidifier unit needs to be started from the beginning to cool down the ambient temperature to avoid abnormal operation of the internal equipment in the area due to the high internal temperature of the area, thereby reducing production accuracy.

[0067] At the initial , the dehumidifier unit will not start initially; after the equipment in the area has been running for a certain period of time, if , which is fed back to the control unit to control the dehumidification unit to start and cool down the area to avoid the high ambient temperature raising the equipment temperature, or to avoid the high equipment temperature but the temperature sensor 19 failing to detect the actual temperature change in time, which affects the abnormal operation of the internal equipment and reduces the production accuracy.

[0068] S2: Determine and adjust the air volume;

[0069] exist , When the dehumidifier unit is running, the air volume of the jet duct 11 cannot meet the cooling demand of the area, and the feedback is sent to the counting unit and the control unit. The counting module counts the air handling units that cannot meet the cooling demand of the corresponding area, and the count value is N.

[0070] In order to ensure the normal operation of the dehumidification unit inside the workshop and ensure that the control unit can perform normal air volume allocation, an allocation threshold is set in the analysis unit. Only within the allocation threshold can the air volume be allocated. The air volume threshold is recorded as A. , that is, the largest positive integer not greater than half the number of air handling units, When there are no more than three groups of consecutive adjacent high-temperature areas, feedback will be sent to the control unit to control the air volume adjustment; in other cases, feedback will be sent to the early warning module to issue an early warning prompt for handling by the staff.

[0071] S3: Control the air volume adjustment;

[0072] The temperatures in the adjacent areas are , When the control unit is used, the jet air duct 11 near the workshop entrance is preferred, and the Figure 5 The air volume adjustment method shown is used to adjust the air volume of the jet air duct 11, so as to increase the air volume of the main air duct 111 without increasing the operating power of the blower 12 and the dehumidification unit, thereby improving the cooling effect of the area;

[0073] The temperatures in the adjacent areas are or When the control unit is used, the jet air duct 11 near the workshop entrance is preferred and the Figure 6 The air volume adjustment method shown is used to adjust the air volume with the jet air duct 11;

[0074] In other cases, the control unit preferentially selects the jet air duct 11 corresponding to the area with a lower theoretical temperature value, and selects Figure 6 The air volume adjustment method shown is used to adjust the air volume of the jet air duct 11.

[0075] In this embodiment, the dehumidification unit can be controlled to start according to the temperature conditions of various indoor areas. At the same time, according to the actual temperature conditions of each area, the air volume of the main air duct 111 in the jet air duct 11 is intelligently adjusted without increasing the operating power of the air supply fan 12 and the dehumidification unit to ensure that the indoor temperature is maintained within a stable range, which not only promotes the circulation of indoor air, but also helps to reduce the indoor humidity and achieve the effect of energy saving and emission reduction.
