[0051] The application discloses a water-cooled kitchen air conditioner.

[0052] Reference below Figure 1-Figure 2 A water-cooled kitchen air conditioner according to an embodiment of the present application is described.

[0053] In some embodiments, the water-cooled kitchen air conditioner includes: an indoor unit, an outdoor unit 100, an inlet water temperature sensor, an outlet water temperature sensor, a flow regulating valve 101 and a controller.

[0054] The outdoor unit 100 is connected to the indoor unit, and the condenser 110 of the outdoor unit 100 has a water-cooling structure. The water inlet pipe 113 of the water-cooling structure is arranged with a switch valve 102, a flow regulating valve 101 and an inlet water temperature sensor. The flow regulating valve 101 is used to adjust the water flow of the water cooling structure. The water outlet pipe 114 of the water cooling structure is arranged with an outlet water temperature sensor. The back plate 192 of the outdoor unit 100 is provided with a water receiving cover 182. The back plate 192 and the water receiving cover 182 define a accommodating cavity. The switch valve 102 and the high-pressure valve 103 and the low-pressure valve 104 of the indoor unit are installed in the accommodating cavity.

[0055] The switch valve 102 may be a solenoid switch valve 102 , an electric switch valve 102 , or a pneumatic switch valve 102 , etc., which is not limited here.

[0056] For example, in some embodiments, the switch valve 102 is a solenoid switch valve 102 .

[0057] In this embodiment, if Figure 1-Figure 2 As shown, the casing of the outdoor unit 100 may include a box cover, a base, a front plate, a back plate and side plates (the complete casing is not shown in the figures), the front plate, the back plate 192 and the side plates may be connected to the base 191, the base, the front plate, the back plate and the side plates may be combined into a box body, the box cover may be suitable for sealing the box body, the back plate 192 may include a valve mounting plate 181, the high-pressure valve 103, the low-pressure valve 104 and the switch valve 102 may be installed on the valve mounting plate 181, the water receiving cover 182 may be connected to the valve mounting plate 181 to define a accommodating chamber, which may accommodate the high-pressure valve 103, the low-pressure valve 104 and the switch valve 102.

[0058] The water inlet temperature sensor may include a temperature sensing package, which can be used to detect the water temperature in the water inlet pipe 113 of the water cooling structure, that is, the water inlet temperature of the water cooling structure; the water outlet temperature sensor may include a temperature sensing package, which can be used to detect the water temperature in the water outlet pipe 114 of the water cooling structure, that is, the water outlet temperature of the water cooling structure.

[0059] The flow control valve 101 can be arranged on the water inlet pipe 113 or the water outlet pipe 114. For example, in some embodiments, Figure 1-Figure 2 As shown, the flow regulating valve 101 is arranged on the water inlet pipe 113 .

[0060] The outdoor unit 100 includes a compressor 160 and a condenser 110, which are part of the refrigeration cycle of the entire water-cooled kitchen air conditioner. When the high-temperature refrigerant flows through the condenser 110, the coolant flowing in the water-cooling structure can absorb the heat of the high-temperature refrigerant, thereby achieving liquid cooling and heat dissipation of the high-temperature refrigerant.

[0061] In actual implementation, after the air conditioner is turned on, the inlet water temperature sensor, the outlet water temperature sensor and the flow regulating valve 101 are all in working state. The inlet water temperature sensor can collect the inlet water temperature of the water cooling structure, and the inlet water temperature sensor can feed back the collected inlet water temperature of the water cooling structure to the controller. The outlet water temperature sensor can collect the outlet water temperature of the water cooling structure, and the outlet water temperature sensor can feed back the collected outlet water temperature of the water cooling structure to the controller. The controller can send a primary command signal to the flow regulating valve 101 based on the inlet water temperature of the water cooling structure. In response to the primary command signal sent by the controller, the flow regulating valve 101 can make a primary adjustment to the opening size; then the controller can send a secondary command signal to the flow regulating valve 101 based on the outlet water temperature of the water cooling structure. In response to the secondary command signal sent by the controller, the flow regulating valve 101 can make a secondary adjustment to the opening size.

[0062] The water-cooled kitchen air conditioner provided in the embodiment of the present application can adjust the water flow of the condenser 110 in real time through its own system through the settings of the above-mentioned water inlet temperature sensor, water outlet temperature sensor, and flow regulating valve 101, so as to achieve the purpose of energy saving and water saving, thereby improving the economy of the water-cooled kitchen air conditioner. At the same time, the outlet water temperature can be controlled by adjusting the water inlet temperature, and the outlet water temperature can be maintained at an appropriate level for a long time after the air conditioner is turned on, thereby optimizing the heat exchange performance of the condenser 110, thereby improving the operating energy efficiency and safety performance of the whole machine. In addition, the high-pressure valve 103, the low-pressure valve 104, and the switch valve 102 are hidden in the accommodating cavity, which not only protects the high-pressure valve 103, the low-pressure valve 104, and the switch valve 102, but also prevents the high-pressure valve 103, the low-pressure valve 104, and the switch valve 102 from being exposed, resulting in accelerated aging and corrosion, thereby extending the service life of the high-pressure valve 103, the low-pressure valve 104, and the switch valve 102.

[0063] In some embodiments, Figure 1-Figure 2 As shown, the water-cooled kitchen air conditioner may further include: a water inlet connector 140 .

[0064] The water inlet joint 140 may be adapted to be connected between the inlet of the water inlet pipe 113 and a water source.

[0065] In this embodiment, if Figure 1-Figure 2 As shown, the water inlet connector 140 can be a conventional four-point internal thread hexagonal connector, which can be directly connected to a tap; the switch valve 102 can be connected to the water inlet connector 140 through a three-point water pipe, and its buckle-type structure can be easily installed and disassembled, and the length of the water pipe can be cut according to actual needs.

[0066] The water-cooled kitchen air conditioner provided in the embodiment of the present application realizes the connection between the water source and the water inlet of the water cooling structure and the on-off control of the water inlet pipe 113 through the setting of the above-mentioned water inlet joint 140, and the switch valve 102 and the high-pressure valve 103 are set on the same side, which is convenient for relevant operators to realize the operation of connecting the refrigerant pipe and the water pipe on the same side.

[0067] In some embodiments, Figure 1-Figure 2 As shown, the switch valve 102 can be connected between the flow regulating valve 101 and the water inlet joint 140 .

[0068] In this embodiment, if Figure 1-Figure 2 As shown, the flow regulating valve 101 may be arranged in the casing of the outdoor unit 100 , and the switch valve 102 may be located outside the casing of the outdoor unit 100 .

[0069] In other embodiments, the flow regulating valve 101 and the switch valve 102 may be disposed in a casing of the outdoor unit 100 .

[0070] In some other embodiments, the flow regulating valve 101 and the switch valve 102 may be arranged outside the casing of the outdoor unit 100 .

[0071] The water-cooled kitchen air conditioner provided in the embodiment of the present application, through the position design of the above-mentioned flow regulating valve 101, the switch valve 102 and the water inlet joint 140, compared with the structure in which the flow regulating valve 101 is arranged between the switch valve 102 and the water inlet joint 140, prevents water from being stored between the flow regulating valve 101 and the water inlet joint 140 for a long time after the switch valve is closed, thereby increasing the convenience of maintenance work of the flow regulating valve 101.

[0072] In some embodiments, Figure 1-Figure 2 As shown, the flow regulating valve 101 and the switch valve 102 may be located at different sides of the water cooling structure, and the flow regulating valve 101 and the switch valve 102 may be connected via an elbow 150 .

[0073] In this embodiment, if Figure 1-Figure 2 As shown, the flow regulating valve 101 can be arranged in the casing of the outdoor unit 100, the switch valve 102 can be located outside the casing of the outdoor unit 100, the flow regulating valve 101 and the switch valve 102 can be located on adjacent sides of the water cooling structure, and the transition of the pipeline direction between the flow regulating valve 101 and the switch valve 102 can be completed through the elbow 150.

[0074] Preferably, viewed along the direction of water inlet, the pipe opening on the switch valve 102 can be snap-fitted and connected with the four-point internal thread to three-point elbow 150, and the four-point internal thread of the elbow 150 can be tightened and connected with the external thread of the flow control valve 101.

[0075] The water-cooled kitchen air conditioner provided in the embodiment of the present application realizes the arrangement of the flow regulating valve 101 and the switch valve 102 on different sides through the position design of the above-mentioned flow regulating valve 101 and the switch valve 102, in conjunction with the setting of the elbow 150. Compared with the structure arranged on the same side, the space occupied by the water inlet pipe 113 is effectively reduced, which is beneficial to the overall spatial layout of the outdoor unit 100 and facilitates the maintenance of the flow regulating valve 101 and the switch valve 102.

[0076] In some embodiments, Figure 1 As shown, the water-cooled kitchen air conditioner may further include: a liquid sealing device 120 .

[0077] The liquid sealing device 120 may be installed on the water outlet pipe 114 , and the liquid sealing device 120 may be used to seal the coolant in the water cooling structure.

[0078] In this embodiment, if Figure 1 As shown, the liquid sealing device 120 can be a liquid sealing tube, wherein the outer diameter of the liquid sealing tube can be two-tenths, three-tenths or four-tenths, etc. Preferably, the outer diameter of the liquid sealing tube can be three-tenths, and the liquid sealing device 120 can be located at the inlet of the water outlet pipe 114. The liquid sealing device 120 can be provided with at least one water trap structure. When the air conditioner is in working state, coolant continuously enters and is discharged from the water cooling structure, and the heat of the refrigerant is continuously taken away by the flow of coolant. Even if the air conditioner is in a shutdown state, at least part of the coolant is blocked in the water cooling structure by the liquid sealing tube.

[0079] The shape of the liquid sealing device 120 may include but is not limited to an S-shape, a U-shape or a P-shape, etc., which is not limited here.

[0080] For example, in some embodiments, the liquid sealing device 120 is in an S-shape.

[0081] The water-cooled kitchen air conditioner provided in the embodiment of the present application, through the setting of the above-mentioned liquid sealing device 120, allows the coolant to be stored in the water-cooling structure for a long time. On the one hand, it can prevent the presence of air in the water-cooling structure and reduce the risk of pipeline corrosion; on the other hand, it can prevent foreign objects such as insects from entering the water-cooling structure to prevent pipeline blockage.

[0082] In some embodiments, Figure 1 As shown, the water-cooled kitchen air conditioner may further include: a drainage joint 130 .

[0083] The drainage joint 130 may have a first interface, a second interface and a drainage port, the first interface may be connected to the outlet of the water outlet pipe 114, the second interface may be connected to the drainage pipe of the indoor unit, and the drainage port may be used to be connected to a sewer.

[0084] In this embodiment, if Figure 1As shown, the drain connector 130 can be a two-in-one connector. In other words, the first interface and the second interface can be two inlets of the drain connector 130, and the drain outlet can be one inlet of the drain connector 130, so that the hot water of the water-cooled structure and the sewage of the indoor unit can be discharged together through the drain outlet of the drain connector 130. In the case where the above-mentioned liquid sealing device 120 is a liquid sealing pipe, in order to facilitate the installation of accessories, the liquid sealing pipe can be installed on the water outlet pipe 114 by snap-fitting, and the water outlet pipe 114 can be connected to the first interface of the drain connector 130 by snap-fitting.

[0085] The water-cooled kitchen air conditioner provided in the embodiment of the present application, through the setting of the above-mentioned drain joint 130, combined with the setting of the first interface, the second interface and the drain outlet, guides the water outlet of the outdoor unit 100 and the drain outlet of the indoor unit to the same drain pipe, thereby realizing unified drainage of the outdoor unit 100 and the indoor unit, reducing the number of drain pipes used, saving manufacturing costs and facilitating drainage for users.

[0086] In some embodiments, Figure 1 As shown, the first interface may be located at a side of the drain connector 130 , the second interface may be located at an upper end of the drain connector 130 , and the drain port may be located at a lower end of the drain connector 130 .

[0087] In actual implementation, Figure 1 As shown, based on the fact that the water discharged from the condenser 110 has less dirt, while the water discharged from the indoor unit has more dirt, when the second interface is located at the upper end of the drain joint 130 and the drain outlet is located at the lower end of the drain joint 130, the sewage discharged from the indoor unit can quickly enter the drain pipe through the drain outlet under the action of gravity. Even if some dirt remains on the wall of the drain joint 130, when the first interface is located on the side of the drain joint 130, the hot water discharged from the water cooling structure can also flush away the dirt remaining in the drain joint 130.

[0088] The water-cooled kitchen air conditioner provided in the embodiment of the present application prevents dirt from remaining in the drain joint 130 for a long time and causing water blockage through the position design of the above-mentioned first interface, second interface and drain outlet. At the same time, the hot water discharged from the water-cooling structure is used to clean the inside of the drain joint 130, thereby accelerating the discharge rate of sewage from the indoor unit, thereby reducing the maintenance frequency in the drain joint 130.

[0089] In some embodiments, Figure 1-Figure 2 As shown, the condenser 110 may further include a first tube 111 , and the water cooling structure may include: a second tube 112 , a water inlet pipe 113 and a water outlet pipe 114 .

[0091] In this embodiment, if Figure 1-Figure 2 As shown, the first tube 111 can be sleeved outside the second tube 112, the inlet of the first tube 111 can be connected to the outlet of the compressor 160, the outlet of the first tube 111 can form the refrigerant outlet of the condenser 110, the refrigerant outlet can be connected to the air-conditioning indoor unit, the water inlet of the second tube 112 can be connected to the water source, the water outlet of the second tube 112 can be connected to the sewer, the refrigerant inlet can be arranged close to the water outlet, and the refrigerant outlet can be arranged close to the water inlet, that is, the flow directions of the refrigerant and the cooling water in the condenser 110 are opposite to each other, so as to increase the heat exchange between the refrigerant and the cooling water.

[0092] In other embodiments, the second tube 112 may be sleeved outside the second tube 112 .

[0093] like Figure 1-Figure 2 As shown, the flow regulating valve 101 can be connected between the water inlet of the second pipe 112 and the outlet of the water inlet pipe 113, wherein the connection method between the flow regulating valve 101 and the water inlet of the second pipe 112 may include but is not limited to welding, flange connection, plug-in or snap connection, etc., which is not limited here.

[0094] For example, in some embodiments, the flow regulating valve 101 and the water inlet of the second pipe 112 are connected by welding.

[0095] The water-cooled kitchen air conditioner provided in the embodiment of the present application improves the overall integration of the condenser 110 through the arrangement of the above-mentioned first tube 111, the second tube 112, the water inlet pipe 113 and the water outlet pipe 114, thereby reducing the space occupied by the condenser 110, which is beneficial to the overall spatial layout of the outdoor unit 100, and cooperates with the inlet and outlet design of the first tube 111 and the second tube 112 to greatly improve the heat exchange efficiency of the condenser 110.

[0096] In some embodiments, Figure 1-Figure 2 As shown, the condenser 110 may surround the outside of the compressor 160 of the outdoor unit 100 .

[0099] For example, in some embodiments, Figure 1-Figure 2 As shown, the condenser 110 may be coiled four times around the outside of the compressor 160 .

[0100] The water-cooled kitchen air conditioner provided in the embodiment of the present application significantly reduces the space occupied by the condenser 110 and the compressor 160 through the design of the arrangement of the above-mentioned condenser 110 and the compressor 160, and can leave more space in the casing for arranging other components, thereby maximizing the space utilization and achieving an overall miniaturized and lightweight design.

[0101] In some embodiments, Figure 1-Figure 2 As shown, the first tube 111 is sleeved outside the second tube 112 , the refrigerant inlet and the refrigerant outlet of the first tube 111 are both located on the side of the condenser 110 , and the water inlet and the water outlet of the second tube 112 are both located at the end of the condenser 110 .

[0102] In this embodiment, if Figure 1-Figure 2As shown, the entire condenser 110 can be arranged in a square coiled shape, with refrigerant medium flowing through the first tube 111, and cooling water flowing through the second tube. The refrigerant inlet and the refrigerant outlet can be set on the same side or diagonally, and the refrigerant inlet and the refrigerant outlet can be respectively located at the sides of the two ends of the entire condenser 110, the water inlet and the water outlet can be set on the same side or diagonally, and the water inlet and the water outlet can be respectively located at the ends of the two ends of the entire condenser 110, the refrigerant can enter the first tube 111 located in the outer circle from the refrigerant inlet located on the side of the condenser 110, and the refrigerant can leave the first tube 11 located in the outer circle from the refrigerant outlet located on the side of the condenser 110, and the cooling water can enter the second tube 112 located in the inner circle from the water inlet located at the end of the condenser 110, and the cooling water can leave the second tube 112 located in the inner circle from the water outlet located at the end of the condenser 110, and the inner wall of the first tube 111 can contact with the outer wall of the second tube 112 and exchange heat.

[0103] In other embodiments, the second tube 112 can be sleeved outside the first tube 111 , the refrigerant inlet and the refrigerant outlet can be located at the end of the condenser 110 , and the water inlet and the water outlet can be located on the side of the condenser 110 .

[0104] The water-cooled kitchen air conditioner provided in the embodiment of the present application, through the structural design that the second tube 112 is arranged outside the first tube 111, cooperates with the position design of the refrigerant inlet, refrigerant outlet, water inlet and water outlet, separates the refrigerant side and the inlet and outlet as much as possible as well as the inlet and outlet of the water side, reduces the probability of interference between the refrigerant side and the water side, and thus optimizes the performance of the entire water-cooled kitchen air conditioner.

[0105] In some embodiments, Figure 1-Figure 2 As shown, the refrigerant inlet of the first tube 111 is arranged close to the water outlet of the second tube 112 , and the refrigerant outlet of the first tube 111 is arranged close to the water inlet of the second tube 112 .

[0106] In this embodiment, if Figure 1-Figure 2 As shown, the entire condenser 110 can be arranged in a square coiled shape, and the inlet and outlet of the first tube 111 and the inlet and outlet of the second tube 112 can be arranged in reverse. Specifically, the condenser 110 can have a first end and a second end, the refrigerant inlet can be arranged on the side of the first end, the water outlet can be arranged at the end of the first end, the refrigerant outlet can be arranged on the side of the second end, and the water inlet can be arranged at the end of the second end. During the heat exchange process, the flow direction of the refrigerant in the first tube 111 is opposite to the flow direction of the cooling water in the second tube 112.

[0107] The first end and the second end may be arranged on the same side or diagonally, which is not limited here.

[0108] The water-cooled kitchen air conditioner provided in the embodiment of the present application realizes the reverse flow of the refrigerant and the cooling water in the condenser 110 through the position design of the above-mentioned refrigerant inlet, refrigerant outlet, water inlet and water outlet. Compared with the scheme of co-directional flow, the heat exchange between the refrigerant and the cooling water per unit volume per unit time is increased, thereby significantly improving the heat exchange efficiency of the condenser 110.

[0109] The present application also discloses a temperature control method, which is applied to a water-cooled kitchen air conditioner. The water-cooled kitchen air conditioner includes an indoor unit, an outdoor unit 100 and a flow regulating valve 101. The outdoor unit 100 is connected to the indoor unit. The condenser 110 of the outdoor unit 100 has a water-cooling structure. The flow regulating valve 101 is used to adjust the water flow of the water-cooling structure.

[0110] In some embodiments, Figure 3 As shown, the temperature control method includes: step 210, step 220, step 230 and step 240.

[0111] Step 210, when the water-cooled kitchen air conditioner is turned on, the flow regulating valve 101 is opened with a first opening m1, and the water inlet temperature t1 of the water cooling structure is obtained, wherein the first opening m1 is a reference opening calibrated based on the first target temperature T1.

[0112] The water inlet temperature t1 of the water cooling structure can be detected by an inlet water temperature sensor. The water-cooled kitchen air conditioner provided in the present application uses tap water to dissipate heat. Therefore, if the water inlet temperature t1 of the water cooling structure is too high under the same flow rate, the refrigeration effect will be reduced. In order to ensure the consistency of the product's refrigeration capacity, the water flow rate needs to be adjusted. The specific value of the first target temperature T1 can be determined based on big data statistics or other methods. The basic cooling capacity of the water-cooled kitchen air conditioner provided in the present application is determined based on the first target temperature T1, and the first opening m1 of the flow regulating valve 101 is also determined based on the first target temperature T1.

[0113] Step 220 : When the inlet water temperature t1 is greater than the first target temperature T1 , control the opening of the flow control valve 101 to a second opening m2 , wherein the second opening m2 is greater than the first opening m1 .

[0114] Among them, the first target temperature can satisfy: 5℃≤T1≤35℃. Specifically, the first target temperature can be 5℃, 10℃, 12.55℃, 22.5℃, 30.375℃, 35℃ or other values ​​between 5℃ and 35℃, which is not limited here.

[0115] Step 230: Obtain the outlet water temperature t2 of the water cooling structure.

[0116] The outlet water temperature t2 of the water cooling structure can be detected by an outlet water temperature sensor.

[0117] Step 240: Control the opening of the flow control valve 101 based on the outlet water temperature t2.

[0118] In actual implementation, Figure 4 As shown, after the air conditioner is turned on, the water inlet temperature sensor, the water outlet temperature sensor and the flow regulating valve 101 are all in working state, the flow regulating valve 101 is opened with a first opening m1, the water inlet temperature sensor can collect the water inlet temperature t1 of the water cooling structure, and the water inlet temperature sensor can feed back the collected water inlet temperature t1 of the water cooling structure to the controller, the water outlet temperature sensor can collect the water outlet temperature t2 of the water cooling structure, and the water outlet temperature sensor can feed back the collected water outlet temperature t2 of the water cooling structure to the controller, the controller can compare the water inlet temperature t1 with the first target temperature T1, when the comparison result is that the water inlet temperature t1 is greater than the first target temperature T1, the controller can send a primary instruction signal to the flow regulating valve 101, in response to the primary instruction signal sent by the controller, the opening of the flow regulating valve 101 can be increased from the first opening m1 to the second opening m2; then the controller can send a secondary instruction signal to the flow regulating valve 101 based on the water outlet temperature t2 of the water cooling structure, in response to the secondary instruction signal sent by the controller, the flow regulating valve 101 can make a secondary adjustment to the opening size.

[0119] The temperature control method of the water-cooled kitchen air conditioner provided in the embodiment of the present application can adjust the water flow of the condenser 110 in real time through its own system through the logic design of the opening of the multi-stage control flow regulating valve 101 based on the inlet water temperature t1 and the outlet water temperature t2, so as to achieve the purpose of energy and water saving, and thus save the use cost of the water-cooled kitchen air conditioner. At the same time, the outlet water temperature t2 can be controlled by adjusting the inlet water temperature t1, and the outlet water temperature t2 after the air conditioner is turned on can be maintained at an appropriate level for a long time, thereby optimizing the heat exchange performance of the condenser 110, and thus improving the operating energy efficiency and safety performance of the whole machine.

[0120] In some embodiments, Figure 4 As shown, step 240, based on the outlet water temperature t2, controlling the opening of the flow regulating valve 101, may include: when the outlet water temperature t2 is greater than the second target temperature T2, controlling the opening of the flow regulating valve 101 to a third opening m3, wherein the third opening m3 is greater than the first opening m1; when the outlet water temperature t2 is not greater than the second target temperature T2, controlling the opening of the flow regulating valve 101 to remain unchanged.

[0121] Among them, the second target temperature T2 can satisfy: 55℃≤T2≤75℃. Specifically, the second target temperature T2 can be 55℃, 60℃, 65.25℃, 67.5℃, 72.375℃, 75℃ or other values ​​between 55℃ and 75℃, which is not limited here.

[0122] It should be noted that the second target temperature T2 is determined based on the basic cooling capacity of the water-cooled kitchen air conditioner. Specifically, the basic cooling capacity of the water-cooled kitchen air conditioner is determined based on the first target temperature T1. After the determination is completed, the second target temperature T2 can be experimentally calibrated according to the determined basic cooling capacity.

[0123] For example, based on a 3500W water-cooled kitchen air conditioner, that is, a water-cooled kitchen air conditioner with a cooling capacity of 1.5 horsepower, based on experimental data, the benchmark water outlet temperature of this capacity is 70°C.

[0124] In actual implementation, Figure 4 As shown, the outlet water temperature sensor can collect the outlet water temperature t2 of the water cooling structure, and the outlet water temperature sensor can feed back the collected outlet water temperature t2 of the water cooling structure to the controller. After the controller completes the first-level adjustment, the controller can compare the outlet water temperature t2 and the second target temperature T2. When the comparison result is that the outlet water temperature t2 is greater than the second target temperature T2, the controller can send a secondary command signal to the flow control valve 101. In response to the secondary command signal sent by the controller, the opening of the flow control valve 101 can be increased from the current opening to the third opening m3; when the comparison result is that the outlet water temperature t2 is not greater than the second target temperature T2, the controller can send a secondary command signal to the flow control valve 101. In response to the secondary command signal sent by the controller, the flow control valve 101 can maintain the current opening unchanged.

[0125] It should be noted that before the flow regulating valve 101 makes the secondary adjustment, if the controller controls the opening of the flow regulating valve 101 to increase based on the inlet water temperature t1, the current opening of the flow regulating valve 101 is the second opening m2; if the controller controls the opening of the flow regulating valve 101 to remain unchanged based on the inlet water temperature t1, the current opening of the flow regulating valve 101 is the first opening m1.

[0126] The temperature control method of the water-cooled kitchen air conditioner provided in the embodiment of the present application, through the above-mentioned logical design of controlling the opening of the flow regulating valve 101 to increase or remain unchanged based on the outlet water temperature t2, maintains the consistency of the outlet water temperature t2 of the condenser 110 to the maximum extent, reduces the condensing pressure when the condenser 110 is in operation, optimizes the heat dissipation performance of the condenser 110, and improves the operating efficiency and safety performance of the whole machine.

[0127] In some embodiments, Figure 4 As shown, the outlet water temperature t2 may be: the outlet water temperature t2 obtained after the target time from the last adjustment of the flow control valve 101.

[0128] Among them, the target duration can be 2 minutes to 10 minutes. Specifically, the target duration can be 2 minutes, 2.5 minutes, 3.25 minutes, 5 minutes, 7.225 minutes, 10 minutes or other values ​​between 2 minutes and 10 minutes, which are not limited here.

[0129] It is understandable that since it takes a certain amount of time for the cooling water to flow and exchange heat, it is impossible to achieve the effect of an immediate change in the outlet water temperature t2 just after adjusting the water flow rate, so the target duration is used as the buffer time between two adjacent cycles.

[0130] In actual implementation, Figure 4 As shown, after the air conditioner is turned on, the outlet water temperature sensor can detect the outlet water temperature t2 of the water cooling structure in real time, and the outlet water temperature sensor does not need to provide real-time feedback to the controller. Specifically, after the outlet water temperature sensor provides the first data feedback to the controller, the controller makes the first adjustment to the flow control valve 101, and the calculation starts from the time point when the first adjustment is completed. After the target time, the outlet water temperature sensor can provide the second data feedback to the controller, and the controller can make the second adjustment to the flow control valve 101, and so on.

[0131] The temperature control method of the water-cooled kitchen air conditioner provided in the embodiment of the present application is configured to adjust the opening of the flow control valve 101 based on the outlet water temperature t2 after the power-on for multiple times, and is combined with a logic design that cycles regularly based on a target duration, so as to prevent the outlet water temperature t2 from having time to react to the previous adjustment before entering the next adjustment, thereby maximizing the control accuracy of the outlet water temperature t2.

[0132] In some embodiments, Figure 4 As shown, after step 210, obtaining the water inlet temperature t1 of the water cooling structure, the method may further include: when the water inlet temperature t1 is not greater than the first target temperature T1, controlling the opening of the flow control valve 101 to remain unchanged.

[0133] In actual implementation, Figure 4As shown, after the air conditioner is turned on, the water inlet temperature sensor, the water outlet temperature sensor and the flow regulating valve 101 are all in working state, the flow regulating valve 101 is opened with the first opening m1, the water inlet temperature sensor can collect the water inlet temperature t1 of the water cooling structure, and the water inlet temperature sensor can feed back the collected water inlet temperature t1 of the water cooling structure to the controller, the water outlet temperature sensor can collect the water outlet temperature t2 of the water cooling structure, and the water outlet temperature sensor can feed back the collected water outlet temperature t2 of the water cooling structure to the controller, the controller can compare the water inlet temperature t1 with the first target temperature T1, when the comparison result is that the water inlet temperature t1 is greater than the first target temperature T1, the controller can send a primary instruction signal to the flow regulating valve 101, and in response to the primary instruction signal sent by the controller, the opening of the flow regulating valve 101 can be increased from the first opening m1 to the second opening m2; when the comparison result is that the water inlet temperature t1 is not greater than the first target temperature T1, the controller can send a primary instruction signal to the flow regulating valve 101, and in response to the primary instruction signal sent by the controller, the flow regulating valve 101 can maintain the first opening m1.

[0134] The controller can then compare the outlet water temperature t2 and the second target temperature T2. When the comparison result is that the outlet water temperature t2 is greater than the second target temperature T2, the controller can send a secondary command signal to the flow regulating valve 101. In response to the secondary command signal issued by the controller, the opening of the flow regulating valve 101 can be increased from the current opening to the third opening m3; when the comparison result is that the outlet water temperature t2 is not greater than the second target temperature T2, the controller can send a secondary command signal to the flow regulating valve 101. In response to the secondary command signal issued by the controller, the flow regulating valve 101 can maintain the current opening unchanged.

[0135] It should be noted that before the flow regulating valve 101 makes the secondary adjustment, if the controller controls the opening of the flow regulating valve 101 to increase based on the inlet water temperature t1, the current opening of the flow regulating valve 101 is the second opening m2; if the controller controls the opening of the flow regulating valve 101 to remain unchanged based on the inlet water temperature t1, the current opening of the flow regulating valve 101 is the first opening m1.

[0136] The temperature control method of the water-cooled kitchen air conditioner provided in the embodiment of the present application, through the above-mentioned logical design of controlling the opening of the flow regulating valve 101 based on the inlet water temperature t1 to remain unchanged, can maintain the consistency of the inlet water temperature t1 when it is detected that the inlet water temperature t1 reaches an appropriate level, thereby optimizing the heat exchange performance of the condenser 110, thereby improving the performance stability of the water-cooled kitchen air conditioner.
