Description

Technical Field

[0001] This utility model relates to the field of variable frequency air conditioning technology, specifically a variable frequency speed control air conditioning pressure stabilization and water replenishment device. Background Technology

[0002] Air conditioning circulating water systems require stable pressure; both high and low pressure can negatively impact the system. Excessive pressure can cause the circulating water pipes to burst; insufficient pressure allows free and dissolved gases in the circulating water to escape, creating airlocks and hindering circulation in parts or the entire system, resulting in inadequate heating or cooling.

[0003] A search revealed a variable frequency speed control air conditioner pressure stabilizing and water replenishment device disclosed in Chinese Patent Publication No. CN202547028U. The device includes: a water tank connected to a tap water network via an inlet pipe; an outlet of the water tank connected to the inlets of two variable frequency water pumps; an outlet of the variable frequency water pumps connected to a pressure stabilizing and water replenishment pipe connected to an air conditioner circulating water network; a pressure tank connected to the pressure stabilizing and water replenishment pipe; a pressure sensor installed on the pressure tank; an inlet of a pressure relief valve connected to the pressure stabilizing and water replenishment pipe; an outlet of the pressure relief valve connected to the water tank; and the motors of the two variable frequency water pumps, the pressure relief valve, the pressure sensor, and the variable frequency control box electrically connected.

[0004] The above scheme uses two variable frequency water pumps. The pump speed is adjusted via a variable frequency speed-regulating motor, utilizing the nQ and HQ characteristics of the pumps to achieve constant pressure and variable flow operation, thus producing a constant pressure effect to stabilize the air conditioning circulating water network. This invention utilizes the advantages of variable frequency stepless speed regulation to provide stable operating pressure for the air conditioning circulating water system, enabling safe and reliable system operation. For instantaneous pressure fluctuations in the air conditioning circulating water system, a pressure tank is used to absorb these fluctuations. A pressure relief valve is installed; when the air conditioning circulating water system experiences excessive pressure due to high temperature, the valve can be opened to release pressure and prevent damage to the air conditioning circulating water pipeline. However, the pressure bladder inside the pressure tank in the above device is affected by thermal contraction, causing unstable pressure inside the bladder, thus increasing the pressure regulation frequency of the device and increasing operating costs. Utility Model Content

[0005] The purpose of this utility model is to provide a variable frequency speed control air conditioner pressure stabilization and water replenishment device, which has the characteristics of stable structure, low power consumption, and reduced operating costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a variable frequency speed control air conditioner pressure stabilization and water replenishment device, comprising a pressure stabilization mechanism, the pressure stabilization mechanism comprising a pressure stabilization tank, the pressure stabilization tank having a pressure stabilization cavity, the pressure stabilization cavity being slidably connected to a sliding sealing plate, the sliding sealing plate being fixedly connected to multiple cylinders, each of the multiple cylinders having a sliding cavity, the sliding cavity being fixedly connected to an elastic element, the elastic element being fixedly connected to a sliding rod, the sliding rod being fixedly connected to a sealing plate, and the sealing plate being fixedly mounted with a pressure sensor.

[0007] In order to detect the internal pressure of the pressure stabilizing chamber, as a preferred embodiment of the variable frequency speed control air conditioner pressure stabilizing and water replenishment device of this utility model, the sliding chamber is slidably connected to the sliding rod, and the input end of the pressure sensor is connected to the pressure stabilizing chamber.

[0008] To facilitate future maintenance of this device, in a preferred embodiment of the variable frequency speed control air conditioner pressure stabilization and water replenishment device of this utility model, the pressure stabilizing tank is connected to an air conditioner circulating water pipeline, and a first electric regulating butterfly valve is fixedly installed in the air conditioner circulating water pipeline.

[0009] In order to facilitate pressurization of the internal air conditioning circulating water pipe network, as a preferred embodiment of the variable frequency speed control air conditioning pressure stabilization and water supply device of this utility model, the pressure stabilizing tank is connected to a water supply pipe, and a variable frequency water pump is fixedly installed on the water supply pipe.

[0010] In order to maintain pressure inside the air conditioning circulating water pipe network, as a preferred embodiment of the variable frequency speed control air conditioning pressure stabilization and water supply device of this utility model, the water supply pipe is fixedly installed with a third electric regulating butterfly valve, and the water supply pipe is connected to a water tank.

[0011] In order to achieve unified control of the control components of this device, as a preferred embodiment of the variable frequency speed control air conditioner pressure stabilization and water replenishment device of this utility model, the water tank is connected to the tap water network, and the control box is fixedly installed on the water tank.

[0012] To facilitate drainage and pressure relief within the air conditioning circulating water pipe network, as a preferred embodiment of the variable frequency speed control air conditioning pressure stabilization and water replenishment device of this utility model, the water tank is connected to a pressure relief pipe, a second electric regulating butterfly valve is fixedly installed on the pressure relief pipe, and the pressure relief pipe is connected to the pressure stabilizing tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the elasticity of the elastic element. When the internal pressure of the pressure stabilizing chamber is too high or too low, the elastic element will be subjected to compression or tension, causing the sliding rod to slide up and down inside the sliding chamber. At the same time, it drives the sliding sealing plate to slide up and down inside the pressure stabilizing chamber, thereby increasing or decreasing the pressure in the upper sealing space of the pressure stabilizing chamber, that is, increasing or decreasing the pressure in the pressure stabilizing chamber space above the sliding sealing plate. When the pressure sensor detects the increase or decrease in the pressure in the pressure stabilizing chamber space above the sliding sealing plate, the pressure sensor transmits the pressure information to the control component for pressure adjustment, thus achieving the purpose of stable pressure regulation of this device.

[0015] 2. This utility model receives pressure information from a pressure sensor via a control box. When the pressure is too low, the control box controls the third electric regulating butterfly valve to open and the variable frequency water pump to start, thus pressurizing and replenishing water inside the pressure stabilizing chamber and simultaneously pressurizing and replenishing water inside the air conditioning circulating water network. When the pressure sensor displays normal pressure, the control box controls the third electric regulating butterfly valve to close. When the pressure is too high, the second electric regulating butterfly valve is opened to release pressure. When the pressure sensor displays normal pressure, the control box controls the second electric regulating butterfly valve to close. This allows for pressure regulation inside the pressure stabilizing chamber and inside the air conditioning circulating water network, achieving the purpose of convenient pressure stabilization and water replenishment of this device.

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0023] Please see Figures 1 to 3 A variable frequency speed control air conditioner pressure stabilization and water replenishment device includes a pressure stabilization mechanism 1. The pressure stabilization mechanism 1 includes a pressure stabilization tank 101. The pressure stabilization tank 101 has a pressure stabilization chamber 102. The pressure stabilization chamber 102 is slidably connected to a sliding sealing plate 103. The sliding sealing plate 103 is fixedly connected to a plurality of cylinders 104. Each of the plurality of cylinders 104 has a sliding chamber 105. The sliding chamber 105 is fixedly connected to an elastic element 106. The elastic element 106 is fixedly connected to a sliding rod 107. The sliding rod 107 is fixedly connected to a sealing plate 108. The sealing plate 108 is fixedly mounted with a pressure sensor 109. The sliding chamber 105 is slidably connected to the sliding rod 107. The input end of the pressure sensor 109 is connected to the pressure stabilization chamber 102.

[0024] In this embodiment: due to the elastic action of the elastic element 106, when the internal pressure of the pressure stabilizing chamber 102 is too high or too low, the elastic element 106 will be subjected to compression or tension force, thereby causing the sliding rod 107 to slide up and down inside the sliding chamber 105, and at the same time driving the sliding sealing plate 103 to slide up and down inside the pressure stabilizing chamber 102, thereby increasing or decreasing the pressure in the upper sealing space of the pressure stabilizing chamber 102, that is, increasing or decreasing the pressure in the space of the pressure stabilizing chamber 102 above the sliding sealing plate 103. When the pressure sensor 109 detects that the pressure in the space of the pressure stabilizing chamber 102 above the sliding sealing plate 103 has increased or decreased, the pressure sensor 109 transmits the pressure information to the control component for pressure adjustment, thus achieving the purpose of stable pressure adjustment of this device. This solves the problem that the pressure inside the air bladder of the pressure tank in the above device is affected by the heat and cold contraction, making the pressure inside the air bladder unstable, thereby increasing the pressure adjustment frequency of the above device and increasing the operating cost, thus realizing the rationality of the use of this device.

[0025] As a technical optimization of this utility model, the pressure stabilizing tank 101 is connected to the air conditioning circulating water pipe network 2, the air conditioning circulating water pipe network 2 is fixedly installed with a first electric regulating butterfly valve 3, the pressure stabilizing tank 101 is connected to the water supply pipe 4, the water supply pipe 4 is fixedly installed with a variable frequency water pump 5, the water supply pipe 4 is fixedly installed with a third electric regulating butterfly valve 11, the water supply pipe 4 is connected to the water tank 6, the water tank 6 is connected to the tap water pipe network 7, the water tank 6 is fixedly installed with a control box 8, the water tank 6 is connected to the pressure relief pipe 9, the pressure relief pipe 9 is fixedly installed with a second electric regulating butterfly valve 10, and the pressure relief pipe 9 is connected to the pressure stabilizing tank 101.

[0026] In this embodiment: the control box 8 receives pressure information from the pressure sensor 109. When the pressure is too low, the control box 8 controls the third electric regulating butterfly valve 11 to open and the variable frequency water pump 5 to start, thus pressurizing and replenishing water inside the pressure stabilizing chamber 102 and simultaneously pressurizing and replenishing water inside the air conditioning circulating water network 2. When the pressure sensor 109 displays normal pressure, the control box 8 controls the third electric regulating butterfly valve 11 to close. When the pressure is too high, the second electric regulating butterfly valve 10 is opened to release pressure. When the pressure sensor 109 displays normal pressure, the control box controls the second electric regulating butterfly valve 10 to close. Thus, the pressure inside the pressure stabilizing chamber 102 and the air conditioning circulating water network 2 can be regulated, achieving the purpose of convenient pressure stabilization and water replenishment of this device.

[0027] The pressure sensor 109, control box 8, second electric regulating butterfly valve 10, third electric regulating butterfly valve 11, and first electric regulating butterfly valve 3 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures. They can also be replaced by other power sources. In this application, the first electric regulating butterfly valve 3 is in a permanently open state. The input end of the pressure sensor 109 is connected to the pressure stabilizing chamber 102. The first electric regulating butterfly valve 3, second electric regulating butterfly valve 10, third electric regulating butterfly valve 11, and pressure sensor 109 are electrically connected to the control box 8.

[0028] Working principle: Due to the elastic action of the elastic element 106, when the internal pressure of the pressure stabilizing chamber 102 is too high or too low, the elastic element 106 will be subjected to compression or tension force, which will cause the sliding rod 107 to slide up and down inside the sliding chamber 105. At the same time, it will drive the sliding sealing plate 103 to slide up and down inside the pressure stabilizing chamber 102, thereby increasing or decreasing the pressure in the upper sealing space of the pressure stabilizing chamber 102, that is, the pressure in the space above the sliding sealing plate 103 of the pressure stabilizing chamber 102 increases or decreases. When the pressure sensor 109 detects the increase or decrease in the pressure in the space above the sliding sealing plate 103 of the pressure stabilizing chamber 102, the pressure sensor 109 transmits the pressure information to the control component for pressure adjustment, thus realizing the stable pressure regulation of this device. The purpose of this device is to receive pressure information from pressure sensor 109 via control box 8. When the pressure is too low, control box 8 controls the third electric regulating butterfly valve 11 to open and the variable frequency water pump 5 to start, thereby pressurizing and replenishing water inside the pressure stabilizing chamber 102 and the air conditioning circulating water network 2. When the pressure sensor 109 shows normal pressure, control box 8 controls the third electric regulating butterfly valve 11 to close. When the pressure is too high, the second electric regulating butterfly valve 10 is opened to release pressure. When the pressure sensor 109 shows normal pressure, control the second electric regulating butterfly valve 10 to close. This allows for pressure regulation inside the pressure stabilizing chamber 102 and the air conditioning circulating water network 2, achieving the purpose of convenient pressure stabilization and water replenishment.
