Description

Technical Field

[0001] The invention relates to a cold storage, and in particular to a constant temperature circulation intelligent control system for the cold storage. Background Art

[0002] The cold source of the cold storage is provided by the condenser unit, and according to the different cold media, it is divided into two forms: water cooling and air cooling. Since the water-cooled cold storage uses water circulation conduction for refrigeration, the refrigeration effect is stable and the humidity can be controlled. It is very suitable for some products that need to maintain a humid environment. Therefore, water-cooled cold storage is the most common.

[0003] In conjunction with the disclosure (announcement) number: CN115773624A, the disclosure (announcement) date: 2023-03-10, a constant temperature and humidity cold storage internal and external dual circulation temperature and humidity control system and control method is disclosed, including: an internal refrigeration and heating cycle module: used to perform an internal active refrigeration and heating cycle of the constant temperature and humidity cold storage through active compression refrigeration and internal heating and heating; an external heat exchange cycle module: used to store natural heat and cold energy in the external environment of the constant temperature and humidity cold storage through external heat exchange cycle media storage; an alternating hot and cold internal temperature and humidity module: used to perform internal active heat exchange temperature regulation, temperature difference heat exchange temperature regulation and evaporation condensation humidity regulation through an internal heat exchange humidity regulation ring network; a temperature and humidity monitoring system control module: used to control and intelligently manage the internal and external dual circulation system of the constant temperature and humidity cold storage through distributed temperature and humidity monitoring and automatic control intelligent management.

[0004] It can be seen from the above patents that the intelligent control of water-cooled cold storage mainly refers to controlling the temperature on the evaporator. Due to the frequent need to take goods in and out of the cold storage, outside air will enter, causing the water vapor entering the air to condense into frost when it encounters the extremely low temperature evaporator. The existence of the frost layer will hinder the transfer of heat inside the cold storage, reducing the refrigeration effect of the cold storage. When the frost layer becomes thicker and thicker, the refrigeration effect will become worse and worse, and it may even cause the cold storage to fail to work normally. Therefore, the cold storage manager needs to clean the frost layer regularly to keep the internal surface of the cold storage dry and clean. Summary of the invention

DETAILED DESCRIPTION

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] like Figure 1-7 As shown, a cold storage constant temperature cycle intelligent control system includes a processor, a temperature control module, a condenser unit, a network transmission module, an evaporator module 1, a flow rate sensor, a temperature sensor and a pressure sensor, wherein:

[0045] The temperature sensor is used to detect the temperature of the evaporator module 1 and the temperature of the cold storage, and transmit the temperature data to the processor;

[0046] The pressure sensor is used to detect the thickness of frost on the evaporator module 1 and transmit the pressure data to the processor;

[0047] The flow rate sensor is used to detect whether the flow from the condenser unit to the evaporator module 1 is lost, and transmit the flow rate data to the processor;

[0048] The processors include:

[0049] Processing the temperature data and generating instructions to control the temperature of the condenser unit, and then generating first feedback data;

[0050] Determine the current frosting condition of the evaporator module 1 according to the pressure data and the flow rate data and generate second feedback data;

[0051] The first feedback data and the second feedback data are timestamped and transmitted to the user end through the network transmission module.

[0052] Or the user sends instructions to it through the network transmission module to drive the temperature control module.

[0053] It should be noted that the processor, temperature control module, condenser unit, network transmission module, flow rate sensor, temperature sensor and pressure sensor in the above embodiments all belong to the prior art, and their procedures are common technical knowledge of those skilled in the art.

[0054] In the above technology, the monitoring status is transmitted to the mobile phone user terminal through the network transmission module, and the output temperature of the condenser machine can be flexibly adjusted through the mobile phone user terminal, which is convenient and fast to operate.

[0055] As an embodiment further provided by the present invention, the evaporator module 1 comprises a first evaporation plate group 2 and a second evaporation plate group 3 arranged in sequence from the top of the cold storage;

[0056] The pressure sensor is used to detect that after the second evaporation plate group 3 reaches a predetermined weight, the processor controls the condenser unit to switch the cold source from being delivered to the second evaporation plate group 3 to the first evaporation plate group 2 .

[0057] Specifically, the evaporator module 1 in the embodiment is divided into a first evaporation plate group 2 and a second evaporation plate group 3, which can be seen in combination with 2. The pressure sensor is used to detect the frosting condition of the second evaporation plate group 3, and the flow rate sensor is used to detect the condenser unit to deliver the cold source to the second evaporation plate group 3 or the first evaporation plate group 2, that is, when the weight of the second evaporation plate group 3 after frosting reaches a predetermined weight, the processor receives the data transmitted by the pressure sensor and switches the cold source from being delivered to the second evaporation plate group 3 to the first evaporation plate group 2. At this time, the flow rate sensor detects the slow flow change and synchronizes with the processor for verification. Therefore, the second feedback data in the above embodiment includes the situation of the cold source being delivered to the second evaporation plate group 3 or the first evaporation plate group 2 and the frosting weight of the second evaporation plate group 3.

[0058] The temperature sensor for detecting the evaporator module 1 is mainly used for detecting the temperature of the second evaporation plate group 3 .

[0059] In the above technology, the evaporator module 1 is composed of the first evaporation plate group 2 and the second evaporation plate group 3 of the double-layer design, and the flow rate sensor is used to identify which of the first evaporation plate group 2 and the second evaporation plate group 3 is connected to the condenser unit for operation. At the same time, the pressure sensor is used to detect the frosting condition of the second evaporation plate group 3. When the frosting reaches the limit of the load, the condenser unit is connected to the first evaporation plate group 2 for operation, and the connection between the second evaporation plate group 3 and the condenser unit is cut off. At this time, the first evaporation plate group 2 continues to refrigerate, and the cooling temperature is transferred to the second evaporation plate group 3, so the water vapor in the continuously entering air contacts the second evaporation plate group 3 to frost, so that the cold storage is kept at a constant temperature while ensuring the operation of the first evaporation plate group 2, and the interval period of manual defrosting is also extended.

[0060] As another embodiment further provided by the present invention, the first evaporation plate group 2 includes a plurality of groups of two first plates 21 symmetrically arranged in an eight-shaped shape;

[0061] An arc-shaped guide portion 4 is arranged between each group of first plates 21 and is disposed on the roof of the cold storage and convexly extends into the narrow opening of the figure eight. The arc-shaped guide portion 4 is used to guide the cold air between each group of first plates 21 to both sides.

[0062] Specifically, the first plate 21 in the embodiment is fixed to the walls on opposite sides of the cold storage by means of mounting rods 22. Figure 2 As shown. Every two first plates 21 arranged symmetrically in an eight-shaped shape form a group, and the first evaporation plate group 2 is arranged in a plurality of linear arrays. The first plates 21 arranged symmetrically in an eight-shaped shape have their narrow openings facing the roof of the cold storage, and their wide openings facing the second evaporation plate group 3.

[0063] Furthermore, the arc guide 4 of the embodiment is located between each of the two first plates 21 symmetrically arranged in an eight-shaped shape, which is made of an insulation board. A fin module 5 composed of a plurality of stacked fins is also provided between each two groups. The fin module 5 is fixedly installed on the roof of the cold storage, and is used to absorb the dissipated temperature of the first plates 21 on both sides. Since its narrow opening faces the second evaporation plate group 3, a relative space is formed. When the first evaporation plate group 2 is connected to the condenser unit, the temperature of this space is lower than the temperature between each group of two first plates 21. Because high temperature will flow to low temperature, under the guidance of the arc guide 4, the airflow between each group of two first plates 21 will be guided by the arc guide 4 and enter the space to be contained by low temperature.

[0064] Furthermore, the low temperature can be released to the outside through the low temperature holding space, which can cool the first evaporation plate group 2 and the second evaporation plate group 3 to a certain extent, that is, achieve a certain compensation, reduce energy loss, and thus reduce power consumption.

[0065] As another embodiment further provided by the present invention, the second evaporation plate group 3 includes a plurality of groups of two second plates 31 symmetrically arranged in an inverted eight-shaped shape;

[0066] The wide openings of each group of second plates 31 and each group of first plates 21 are arranged adjacent to each other, and the diameters of the wide openings are consistent.

[0067] Specifically, in the above embodiment, every two second plates 31 symmetrically arranged in an inverted figure eight form a group, and the second evaporation plate group 3 is arranged in a plurality of linear arrays. Because each group of the second evaporation plate group 3 and the first evaporation plate group 2 are in an figure eight shape and are in a mirror image relationship, the purpose is to allow the temperature to form a rectangular cavity between each group of two first plates 21 and each group of two second plates 31. When either the second evaporation plate group 3 or the first evaporation plate group 2 is connected to the condenser unit, a low temperature environment will be formed and the temperature will be maintained to a certain extent, that is, temperature compensation is performed on the two first plates 21 and the two second plates 31 constituting the rectangular cavity.

[0068] Secondly, because the narrow opening of each group of two second plates 31 faces the ground, the high temperature will flow toward the narrow opening of the second plate 31 and contact the second plate 31, and the water vapor therein will condense thereon, i.e., frost will form.

[0069] As another embodiment further provided by the present invention, the plurality of sets of second plates 31 are all rotatably arranged, and the rotation directions are opposite, and the opposite side of one end located at the narrow opening is provided with a protrusion 32;

[0070] The wide-mouth diameters of the two second plates 31 after rotation are smaller than the wide-mouth diameters of the two first plates 21 .

[0071] Further, it also includes a coupling 6 arranged at intervals on the shaft 34;

[0072] The second plate 31 is rotatably assembled on the shaft 34, on which a stopper 33 extending to the coupling 6 is arranged, an elastic member 61 is arranged between the stopper 33 and a fixed portion fixedly arranged in the coupling 6, and a pressure sensor is used to detect the force on the resistance portion of the elastic member 61.

[0073] Specifically, the shaft 34 is fixed to the walls on opposite sides of the cold storage, and the second plate 31 is installed on the shaft 34 through a bearing to achieve circumferential rotation. The existence of the coupling 6 is to limit the rotation direction of the second plate 31. Figure 4 It can be seen that the stopper 33 provided on the second plate 31 extends from the notch on the coupling 6 to the inside of the coupling 6 . A fixing portion is provided inside the coupling 6 , and the elastic member 61 is located between the fixing portion and the stopper 33 .

[0074] The pressure sensor is assembled on the fixed part and is used to detect the squeezing thrust of the elastic member 61 by the blocking member 33 .

[0075] Combination Figure 3 It can be seen that because each group of two second plates 31 is located at one end of the narrow mouth, a protrusion 32 is provided on the opposite side. Combined with 5, it can be seen that the cold source is transmitted to the second plate 31 by the shaft 34, and the second plate 31 is divided into a first part and a second part about the rotating shaft 34, and the protrusion 32 is installed at the end of the second part, because the second part is provided with spaced side channels 35, and the side channels 35 are also arranged on the protrusion 32, and each side channel 35 is connected to the cold source in series through the connecting channel 36 in turn. The first part is provided with a side channel 35. Because when the cold storage starts to operate, the cold source is first transmitted to the second evaporation plate group 3, so the second plate 31 is at a low temperature, and the temperature of the first plate 21 is transmitted by the second plate 31, that is, heat exchange is achieved. Therefore, the air in the cold storage will first frost on the raised portion 32 and the second portion. When the thickness of the frost on the raised portion 32 and the second portion is greater than the damping force of the elastic member 61, the elastic member 61 is deformed due to the pressure. Figure 3As shown, the rotation is 15°-20°, that is, it rotates from the solid line to the dotted line position, so that the narrow diameter of each group of two second plates 31 is increased. At this time, the cold source stops transmitting to the second evaporation plate group 3, and switches to transmitting to the first evaporation plate group 2. In this dotted line state, the temperature of the second plate 31 is carried by the first evaporation plate group 2, and because of the space, the lowest temperature is still maintained between the two adjacent second plates 31 in each group. Therefore, when the air entering from the outside is close to the second evaporation plate group 3, it actively approaches the above position, and continues to frost on the second plate 31, that is, a screen is formed to intercept water vapor, prevent the first evaporation plate group 2 from frosting, or minimize the frosting of the first evaporation plate group 2, thereby delaying the heat transfer inside the cold storage due to the excessive accumulation of the frost layer thickness of the first evaporation plate group 2, which reduces the refrigeration effect of the cold storage.

[0076] As another embodiment further provided by the present invention, the evaporator module 1 further includes a flow channel box 7, and the first evaporation plate group 2 and the second evaporation plate group 3 are connected to two water discharge pipes 71 opened in the flow channel box 7;

[0077] The valve body assembly 8 is also included. The valve body assembly 8 is rotated by the second plate 31 so that any water outlet 71 is connected to the first evaporation plate group 2 or the second evaporation plate group 3 .

[0078] Specifically, in the above embodiment, two channels 77 are provided on the flow channel box 7, and the two channels 77 have two branch channels. The water inlet of the flow channel box 7 is connected to the junction of the two channels 77, and the liquid entering from the water inlet is guided to split into the two branch channels through the second triangular diverter 74 provided therein. Figure 6 It can be seen that a plurality of first flow blocks 75 arranged in a linear array are provided in each partition to slow down the flow rate of the liquid entering the branch channel, and the branch channel is provided with I inlet, II inlet, III inlet, IV inlet, IIV inlet, and IIIV inlet distributed from the junction to the end, wherein:

[0079] The flow channel box 7 includes diversion channels 78 arranged in a linear array, wherein:

[0080] The I water inlet is connected to the sixth branch channel 756, and the IIIV water inlet is connected to the fifth branch channel 755. The fifth branch channel 755 and the sixth branch channel 756 are both connected to the fusion chamber 72 provided on the flow channel box 7, and the fusion chamber 72 is provided with a first triangular flow divider 73. The flow of the refrigerant liquid entering the branch channel 78 is made uniform by the flow diversion of the first triangular flow divider 73.

[0081] The II water inlet is connected to the first branch channel 751, and the IV water inlet is connected to the second branch channel 752. The first branch channel 751 and the second branch channel 752 are both connected to the fusion chamber 72 provided on the flow channel box 7, and the fusion chamber 72 is provided with a first triangular flow divider 73. The flow of the refrigerant liquid entering the branch channel 78 is made uniform by the flow diversion of the first triangular flow divider 73.

[0082] The III water inlet is connected to the fourth diversion channel 754, and the IIV water inlet is connected to the third diversion channel 753. The third diversion channel 753 and the fourth diversion channel 754 are both connected to the fusion chamber 72 provided on the flow channel box 7, and the fusion chamber 72 is provided with a first triangular diverter 73. The diversion of the first triangular diverter 73 makes the flow rate of the refrigerant liquid entering the diversion channel 78 consistent;

[0083] Furthermore, multiple second flow blocks 76 are evenly spaced in the sixth branch channel 756, the third branch channel 753 and the first branch channel 751, and the distance between the branch channel and the second channel groove 77 is gradually reduced from the second flow blocks 76 in the above three branch channels, the purpose of which is to reduce the flow rate of the three branch channels so that the flow rates of the three fast flow channels tend to be consistent. Then, they are respectively merged with the fifth branch channel 755, the fourth branch channel 754 and the second branch channel 752 with low flow rates, so that the flow rate and flow rate entering the branch channel 78 are consistent.

[0084] It should be noted that, in the above embodiments, the diameters of the nozzles I, II, III, IV, IIV and IIIV increase from nozzle I to nozzle IIIV.

[0085] As another embodiment further provided by the present invention, the valve body assembly 8 includes a push rod 81 and a sleeve rod 82, two water discharge pipes 71 are arranged on the sleeve rod 82, and the push rod 81 includes a water inlet and two water outlets.

[0086] Furthermore, it also includes a cam 9 that moves synchronously with the second plate 31, and the side surface of the cam 9 is rollingly connected to the end of the push rod 81.

[0087] Specifically, Figure 7 It can be seen that the sleeve rod 82 is connected to the water outlet of the diversion channel 78, and of the two water outlets on the sleeve rod 82, the upper water outlet is connected to the first evaporation plate group 2, and the lower water outlet is connected to the second evaporation plate group 3. When the cam 9 rotates, it pushes the push rod 81 to move upward, so that the diversion channel 78 is connected to the first evaporation plate group 2; or when the cam 9 is not pushing, it drives the push rod 81 to return to its original position, and the diversion channel 78 is connected to the second evaporation plate group 3.

[0088] Furthermore, a track wheel 91 rotating in the coupling 6 is provided on the axial end of the second plate 31, and a driven gear 92 on the shaft of the cam 9 meshes with the track wheel 91. Therefore, when the second evaporation plate group 3 deflects due to the thickness of frost, the track wheel 91 drives the driven gear 92 to rotate, so that the cam 9 rotates and the convex surface pushes the push rod 81 to move, thereby connecting the diversion channel 78 with the first evaporation plate group 2, thereby cutting off the connection with the second evaporation plate group 3.

[0089] It should be noted that, combined with Figure 2 It can be seen that the flow channel box 7 and the return water tank 100 in the embodiment are symmetrically arranged and installed on the walls on opposite sides of the cold storage, and then the refrigerant liquid of the first evaporation plate group 2 and the second plate 31 will enter the return water tank 100 and finally flow back to the condenser unit.

[0090] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
