The outdoor unit can adjust the speed according to the indoor load, saving energy and electricity, and can meet the individual differences in people's temperature requirements, so that the flow rate and load are matched.

[0003] For example, CN204141793U discloses a refrigerant water control circuit for a central air-conditioning unit, the key points of its technical solution are: it includes a fuse FU, a switch selection circuit, a valve actuator, a power indicator light and a display feedback circuit, three-phase electricity is output through the fuse FU, one output is connected to the neutral line through the power indicator light; the other output of the fuse FU is connected to the switch selection circuit, the switch selection circuit controls the opening and closing of the valve actuator, and the valve actuator provides an input signal for the feedback display circuit; it mainly realizes remote control by connecting the manual automatic selection switch SA at the automatic end when the equipment is normally in remote mode, and the remote server controls the opening and closing of the remote opening valve KF1 and the remote closing valve GF1, and then controls the forward and reverse rotation of the valve motor, thereby controlling the opening and closing of the valve.

[0004] The above-mentioned central air-conditioning refrigerant control structure with flow and load matching still has certain shortcomings: since the dust screen is connected to the central air-conditioning refrigerant control structure by bolts, once the dust screen needs to be cleaned, the removal of multiple sets of bolts will increase the time required for cleaning, thereby reducing the working efficiency of the device. Therefore, it is necessary to provide a central air-conditioning refrigerant control structure with flow and load matching. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a central air-conditioning refrigerant control structure with flow and load matching, comprising a central air-conditioning refrigerant control structure body, the front of the central air-conditioning refrigerant control structure body is provided with four installation grooves in a rectangular array, and the interior of the installation groove is bonded with a limiting ring, the front of the central air-conditioning refrigerant control structure body is clamped with a dustproof net through the limiting ring, and the back of the dustproof net is fixedly installed with four limiting rods in a rectangular array, and two connecting handles are welded symmetrically along the center on the front of the dustproof net, and two connecting nuts are symmetrically inlaid and installed along the center on the lower surface of the central air-conditioning refrigerant control structure body, and a liquid collection component is detachably installed on the lower surface of the central air-conditioning refrigerant control structure body through the connecting nuts.

[0007] Among them, the side wall of the central air-conditioning refrigerant control structure body is symmetrically connected with two connecting pipes along the center, and the side wall of the central air-conditioning refrigerant control structure body is detachably installed with a controller.

[0008] The material of the limiting ring is a rubber component, the interior of the limiting ring is matched with the outer surface of the limiting rod, and the length of the limiting rod is the same as the depth of the installation groove.

[0009] Wherein, the liquid collection component includes a stable connecting plate and connecting bolts, the lower surface of the stable connecting plate is connected to two connecting bolts along a central symmetrical thread, and the top end of the connecting bolt is connected to the inside of the connecting nut through the stable connecting plate.

[0011] Among them, an installation box is welded at one end of the stabilizing plate, and a collection box is clamped inside the installation box. The length of the collection box is greater than the length of the central air-conditioning refrigerant control structure body, and the middle of the upper surface of the collection box is directly below the air outlet of the central air-conditioning refrigerant control structure body.

[0012] The beneficial effects of the above technical solution of the utility model are as follows:

[0013] 1. In the above scheme, the central air-conditioning refrigerant control structure is provided with a liquid collection component. Before the central air-conditioning refrigerant control structure body is used, the hydraulic lifting cylinder inside the liquid collection component is first started to drive the installation box and the collection box to move upward until the upper surface of the collection box is fitted with the lower surface of the central air-conditioning refrigerant control structure body. Because the length of the collection box is greater than the length of the central air-conditioning refrigerant control structure body, and the collection box is arranged directly below the air outlet of the central air-conditioning refrigerant control structure body, when the central air-conditioning refrigerant control structure body is used, the liquid will drip into the collection box for collection, thereby preventing the liquid from dripping onto the floor of the room, thereby enhancing the practicality of the device;

[0014] 2. In the above scheme, the central air-conditioning refrigerant control structure is provided with installation grooves, limit rings, limit rods and connecting handles. When the dust screen needs to be disassembled and cleaned, it is only necessary to hold the surface of the two sets of connecting handles and stretch them outward to pull the limit rod out from the inside of the limit ring, so that the dust screen can be disassembled. Because the limit rod is clamped in the inside of the limit ring, it can be directly pulled out. Compared with the bolt connection method to connect the dust screen to the central air-conditioning refrigerant control structure body, this connection method saves time when disassembling the dust screen, thereby improving the working efficiency of the device.

[0020] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1:

[0022] See also Figure 1-3A central air-conditioning refrigerant control structure with flow and load matching, comprising a central air-conditioning refrigerant control structure body 1, four installation grooves 2 are opened in a rectangular array on the front of the central air-conditioning refrigerant control structure body 1, and a limiting ring 3 is bonded inside the installation groove 2. A dustproof net 4 is clamped on the front of the central air-conditioning refrigerant control structure body 1 through the limiting ring 3, and four limiting rods 5 are fixedly installed on the back of the dustproof net 4 in a rectangular array. Two connecting handles 6 are welded symmetrically along the center on the front of the dustproof net 4, and two connecting nuts are inlaid and installed symmetrically along the center on the lower surface of the central air-conditioning refrigerant control structure body 1, and a liquid collecting component 7 is detachably installed on the lower surface of the central air-conditioning refrigerant control structure body 1 through the connecting nut;

[0023] The side wall of the central air-conditioning refrigerant control structure body 1 is symmetrically connected with two connecting pipes 8, and the side wall of the central air-conditioning refrigerant control structure body 1 is detachably installed with a controller 9. The material of the limit ring 3 is a rubber component, and the interior of the limit ring 3 is adapted to the outer surface of the limit rod 5. The length of the limit rod 5 is the same as the depth of the installation groove 2. The liquid collection component 7 includes a stable connecting plate 71 and a connecting bolt 72. The lower surface of the stable connecting plate 71 is symmetrically threaded with two connecting bolts 72. The top of the connecting bolt 72 is connected to the inside of the connecting nut through the stable connecting plate 71. The lower surface of the stable connecting plate 71 is symmetrically installed with two hydraulic lifting cylinders 73 along the center. The bottom end of the hydraulic lifting cylinder 73 is detachably installed with a stable plate 74, and one end of the stable plate 74 is welded with an installation box 75. The interior of the installation box 75 is clamped with a collection box 76. The length of the collection box 76 is greater than the length of the central air-conditioning refrigerant control structure body 1, and the middle of the upper surface of the collection box 76 is directly below the air outlet of the central air-conditioning refrigerant control structure body 1.

[0024] Benefits: By setting the material of the limiting ring 3 to a rubber component, it is helpful to increase the friction between the limiting ring 3 and the limiting rod 5, thereby ensuring the stability of the dustproof net 4 during installation.

[0025] The working process of the utility model is as follows:

[0026] In order to avoid liquid dripping when the central air-conditioning refrigerant control structure body 1 is in use, a liquid collecting component 7 is provided. Before the central air-conditioning refrigerant control structure body 1 is used, the hydraulic lifting cylinder 73 inside the liquid collecting component 7 is first started to drive the installation box 75 and the collection box 76 to move upward until the upper surface of the collection box 76 is fitted with the lower surface of the central air-conditioning refrigerant control structure body 1. Because the length of the collection box 76 is greater than the length of the central air-conditioning refrigerant control structure body 1, and the collection box 76 is arranged directly below the air outlet of the central air-conditioning refrigerant control structure body 1, when the central air-conditioning refrigerant control structure body 1 is used, the liquid will drip into the collection box 76 for collection, thereby avoiding the liquid from dripping onto the floor of the room, thereby enhancing the practicability of the device.

[0027] In the above scheme, when the central air-conditioning refrigerant control structure body 1 is in use, in order to facilitate the cleaning of the dustproof net 4, an installation groove 2, a limit ring 3, a limit rod 5 and a connecting handle 6 are provided. When the dustproof net 4 needs to be disassembled for cleaning, it is only necessary to hold the surface of the two sets of connecting handles 6 and stretch them outward to pull the limit rod 5 out from the inside of the limit ring 3, so that the dustproof net 4 can be disassembled. Because the limit rod 5 is clamped in the inside of the limit ring 3, it can be directly pulled out. Compared with the bolt connection method to connect the dustproof net 4 to the central air-conditioning refrigerant control structure body 1, this connection method saves time when disassembling the dustproof net 4, thereby improving the working efficiency of the device.
