[0002] A heat pump is a device that transfers heat from a low-temperature heat source to a high-temperature heat source. The heat pump extracts heat from a low-temperature heat source (such as air, water, soil, etc.) by consuming a small amount of electrical energy, and then delivers it to the user after raising the temperature.

[0039] See also Figure 1-12 The present invention provides a technical solution for a split frame absorption heat pump heat exchange unit:

[0040] Embodiment 1, a split frame absorption heat pump heat exchanger unit, including a split frame base 1, two groups of circulating water pumps 2 are installed on one side of the upper part of the split frame base 1, two groups of make-up water pump bodies 4 are installed on the other side of the upper part of the split frame base 1, an absorption heat exchanger 3 is installed on the other side of the upper part of the split frame base 1 away from the make-up water pump body 4, the circulating water pump 2, the absorption heat exchanger 3 and the make-up water pump body 4 are connected by pipes and valves, wherein the valves include stop valves, ball valves, butterfly valves, etc., which are not repeated here. At the same time, the design also includes temperature sensors, pressure sensors, flow meters, etc., which monitor the temperature, pressure and flow of hot and cold media in real time. The make-up water pump body 4 includes a make-up water pump cavity 42 installed on the upper part of the split frame base 1, a make-up water motor 41 is installed on the top of the make-up water pump cavity 42, a connecting component is installed on one side of the make-up water pump cavity 42, a buoyancy air guide component is installed on one end of the connecting component, and a gas flow channel conversion component is installed on one side of the buoyancy air guide component;

[0041] The buoyancy gas guide component includes a conversion shell 6 installed with the connecting component, a lifting floating plate 63 is slidably arranged inside the conversion shell 6, and a plurality of exhaust holes 64 are opened on one side of the lifting floating plate 63 (it should be noted that the exhaust area can also be other forms or shapes to achieve the function of gas extraction, such as merging the plurality of exhaust holes 64 into a rectangle), and an exhaust flow channel 65 is opened on the top of the lifting floating plate 63;

[0042] The gas flow channel conversion component includes a gas discharge seat 7 installed on one side of the conversion housing 6, the top of the gas discharge seat 7 is connected to a gas flow guide pipe 71, a gas guide roller 72 is rotatably installed inside one side of the gas discharge seat 7, a gas guide channel 73 is opened in the middle of the gas guide roller 72, and a gas discharge hole 74 is opened at the lower end of the gas discharge seat 7 and at the position corresponding to the gas flow guide pipe 71;

[0043] A transmission assembly is disposed inside the other side of the gas discharge seat 7;

[0044] The connecting component includes a connecting pipe 1 5 connected to the upper end of one side of the water replenishment pump cavity 42, a connecting pipe 2 51 is connected to one side of the water replenishment pump cavity 42 below the connecting pipe 1 5, and a mounting knob 52 is threadedly sleeved on one side of the outer wall of the connecting pipe 1 5 and the connecting pipe 2 51, and a docking end pipe 1 53 is installed on one side of the conversion housing 6 and connected to the corresponding position of the connecting pipe 1 5;

[0045] A butt-end pipe 2 54 is installed on one side of the conversion housing 6 and connected to the corresponding position of the connecting pipe 2 51. A fastening retaining ring 55 is fixed to one side of the outer wall of the butt-end pipe 1 53 and the butt-end pipe 2 54. The outer walls of the butt-end pipe 1 53 and the butt-end pipe 2 54 are provided with threads for use with the installation knob 52. The connecting pipe 1 5 and the butt-end pipe 1 53 as well as the connecting pipe 2 51 and the butt-end pipe 2 54 can be quickly butt-mounted by using the installation knob 52. The threaded connection can be wrapped with leak-proof tape to ensure the sealing performance after installation and avoid leakage of liquid.

[0046] Multiple exhaust holes 64 are all connected to the exhaust flow channel 65, which is used to discharge the gas in the pump body upward. The gravity of the lifting float 63 is less than the buoyancy of the liquid. The interior of the conversion shell 6 is provided with a sliding inner cavity 61 used in conjunction with the lifting float 63. The bottom of the sliding inner cavity 61 is provided with a contraction port 62. The contraction port 62 is arc-shaped, and the contraction port 62 corresponds to the position of the docking end pipe 54. The design of the contraction port 62 can prevent the lifting float 63 from falling to the bottom, affecting the timely entry of liquid, resulting in the lifting float 63 unable to float up in time, affecting the discharge of gas above the water replenishment pump cavity 42.

[0047] In the second embodiment, the upper end of the gas guide tube 71 is connected to the conversion shell 6 for further exporting the gas. The gas guide channel 73 is composed of two symmetrical fan-shaped channels (it should be noted that the gas guide channel 73 can also be opened in a gas shape to achieve the purpose of exporting the gas within a certain range, which will not be repeated here). The fan angle is 40 degrees. The 40-degree design can provide a stroke range for the export of gas, and can achieve the closure of the connection of the gas guide tube 71 when not needed to prevent the outflow of internal liquid. The transmission assembly includes a gear 8 rotatably installed inside the other side of the gas discharge seat 7, and an installation cavity that cooperates with the gear 8 is opened inside the other side of the gas discharge seat 7. A gear 2 81 is rotatably installed on one side of the installation cavity near the gear 1 8. A wire groove 82 is opened on the other side of the lifting float 63 at the position corresponding to the gear 2 81, and a wire tooth 83 used in conjunction with the gear 2 81 is arranged at the lower inner side of the wire groove 82;

[0048] Gear 1 8 is meshedly connected with gear 2 81, and the line tooth 83 is meshedly connected with gear 2 81. The number of teeth of gear 1 8 is four times that of gear 2 81. The rotation axis of gear 1 8 is connected to the rotation axis of the air guide roller 72 through a connecting rod. The speed reduction transmission due to the difference in the number of teeth is used to control the rotation amplitude of the air guide roller 72, and to control the rotation stroke and position change of the air guide channel 73, so as to achieve automatic exhaust without causing the discharge of internal liquid.

[0049] It should be noted that in the above embodiments, some areas that need to be sealed only need to adopt the common sealing methods in the art, and no further elaboration will be given in this application.

[0050] When used specifically, the present invention is a split frame absorption heat pump heat exchanger unit. During operation, the circulating water pump 2 provides power for the circulation of hot medium and cold medium, and the absorption heat exchanger 3 is used to achieve heat transfer between the media. When the water in the heat pump heat exchanger unit is reduced due to leakage or other reasons, the water replenishment pump body 4 automatically replenishes water to the heat pump heat exchanger unit to maintain the normal operating pressure of the system.

[0051] In the process of water replenishment by the water replenishment pump body 4, as the water level rises, the initial position of the air guide roller 72, the air guide channel 73 is in a staggered state with the gas guide tube 71 and the gas discharge hole 74, and at the same time, the interior is closed. When the water level reaches the connecting pipe 2 51, the water will enter the conversion shell 6 through the connecting pipe 2 51 and the docking end pipe 2 54. Under the action of buoyancy, the position of the lifting float 63 will also rise, and the multiple exhaust holes 64 will intersect with the docking end pipe 1 53 in turn. At this time, the gas above the water replenishment pump cavity 42 will flow through the exhaust holes 64 and the exhaust channel 65, and as the lifting float 63 rises, the wire teeth 83 will also mesh with the gear 2 81, and further utilize Gear 2 81 meshes with gear 1 8 to rotate the air guide roller 72. When it rotates to the intersection of the air guide channel 73, the gas guide tube 71 and the gas discharge hole 74, the gas will be discharged directly to the outside. The fan-shaped structure of the air guide channel 73 is used to achieve automatic exhaust within a certain range of travel. When the lifting float 63 floats to the top, the air guide channel 73, the gas guide tube 71 and the gas discharge hole 74 are staggered to complete the internal closure and prevent water from being discharged to the outside. When the water replenishment is completed, the water replenishment pump body 4 stops working. As the water level in the water replenishment pump cavity 42 drops, the lifting float 63 also drops. When the lifting float 63 drops to the lowest position, the air guide roller 72 will also be reset to the initial position.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
