Description

Technical Field

[0001] This utility model belongs to the field of engineering technology, specifically relating to an energy recycling device. Background Technology

[0002] Energy recycling devices refer to technological equipment that captures, converts, and reuses energy that would otherwise be dissipated or emitted from a system in the form of waste heat, vibration, pressure, or kinetic energy. Their core principle lies in adhering to the law of conservation of energy. Through specific technologies such as thermoelectric generators, waste heat boilers, and regenerative braking, these waste energy resources are converted into usable forms such as electrical energy, thermal energy, or mechanical energy, and then fed back to the system itself or used for other functions. Such devices not only effectively improve the overall efficiency of energy utilization and reduce primary energy consumption and operating costs, but also reduce thermal pollution and carbon emissions, making them a key engineering technology for achieving energy conservation, emission reduction, and sustainable development.

[0003] When an air conditioner's outdoor unit is running, it blows out hot air during cooling and cold air during heating. Air conditioners include evaporative chillers and air-cooled heat pump units. Evaporative chillers operate in cooling mode, while air-cooled heat pump units operate in heating mode. When an air-cooled heat pump unit is running, the cold air blown out by the unit's fan is directly directed to the outdoor environment, resulting in some waste and preventing the utilization of the air for maximizing resource utilization. Utility Model Content

[0004] The purpose of this invention is to provide an energy recycling device that aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An energy recycling device includes an air-cooled heat pump unit. An air duct is installed at the air outlet of the air-cooled heat pump unit. An air conditioning room is installed on one side of the air-cooled heat pump unit. The end of the air duct away from the air-cooled heat pump unit extends into the interior of the air conditioning room. A control box is installed inside the air conditioning room. A T-shaped pipe and a U-shaped pipe are respectively installed on the outer side of the air duct and the end of the air duct away from the air-cooled heat pump unit. A second electric valve and a first electric valve are respectively installed on the T-shaped pipe and the U-shaped pipe. A thermocouple is installed inside the air conditioning room.

[0006] As a preferred embodiment of this utility model, both the tee pipe and the U-shaped pipe have through holes, and a box is installed on the outside of both the tee pipe and the U-shaped pipe. A lead screw is rotatably connected inside the box, and a sliding block is slidably connected inside the box. The sliding block is threaded onto the outside of the lead screw, and a sealing plate is installed inside both the U-shaped pipe and the tee pipe.

[0007] In a preferred embodiment of this utility model, the bottom end of the sliding block passes through a through hole and is fixedly connected to the outer wall of the sealing plate.

[0008] In a preferred embodiment of this utility model, the end of the lead screw away from the sliding block passes through the side wall of the box and extends to the outside of the box, and a rotating handle is fixedly connected to the end of the lead screw away from the sliding block.

[0009] In a preferred embodiment of this utility model, the thermocouple, the first electric valve, and the second electric valve are all electrically connected to the control box.

[0010] In a preferred embodiment of this utility model, both ends of the lead screw are rotatably connected to the inner wall of the housing via bearings, and the two rotating handles are respectively located above the three-way pipe and the U-shaped pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This application reuses the energy from cold air blown outdoors, avoiding waste and allowing for its application elsewhere, maximizing energy utilization and achieving cost reduction and efficiency improvement. Through a flow guiding and switching system consisting of ducts, tees, U-shaped pipes, and electric valves, and utilizing thermocouples to monitor the air conditioning room temperature in conjunction with the control box, it achieves the effect of precisely guiding the waste cold air originally discharged outdoors into the computer room for free cooling when cooling is needed. This directly converts waste energy into valuable cooling resources, significantly reducing the active cooling energy consumption of the computer room and maximizing energy utilization.

[0012] 2. A bypass mechanism is provided during valve maintenance, ensuring continuous and stable system operation under various conditions. By installing a screw-driven sliding sealing plate inside the tee and U-shaped pipe, and manually rotating the screw to move the sliding block and sealing plate, the system can quickly and physically isolate the maintenance section while ensuring unobstructed main airflow when electric valves need repair. This achieves "non-stop maintenance" during maintenance, greatly improving system availability and maintenance convenience. Attached Figure Description

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Example 1 Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention, which provides an energy recycling device, including an air-cooled heat pump unit 10, an air duct 11 installed at the air outlet of the air-cooled heat pump unit 10, an air conditioning room 12 installed on one side of the air-cooled heat pump unit 10, the end of the air duct 11 away from the air-cooled heat pump unit 10 extending into the interior of the air conditioning room 12, a control box 13 installed inside the air conditioning room 12, a T-shaped pipe 16 and a U-shaped pipe 14 respectively installed on the outer side of the air duct 11 and the end of the air duct 11 away from the air-cooled heat pump unit 10, and a second electric valve 17 and a first electric valve 15 respectively installed on the T-shaped pipe 16 and the U-shaped pipe 14. The air conditioning room 12 is equipped with thermocouples. The thermocouples, the first electric valve 15, and the second electric valve 17 are all electrically connected to the control box 13. When the air-cooled heat pump unit 10 is operating, the unit fan blows out cold air. A set temperature is set inside the air conditioning room 12 via the control box 13. Thermocouples measure the temperature inside the air conditioning room 12, and the temperature signal is transmitted to the control box 13. When the temperature is higher than the set value, the first electric valve 15 connected to the air conditioning room 12 opens, and the second electric valve 17 connected to the outdoor environment closes. Cold air is then blown into the air conditioning room 12 through the duct 11 and U-shaped pipe 14 for cooling. When the temperature is lower than the set value, the second electric valve 17 connected to the outdoor environment opens, and the first electric valve 15 connected to the air conditioning room 12 closes. Cold air is then blown into the outdoor environment through the T-shaped pipe 16 installed on the outside of the duct 11.

[0017] In operation, the air-cooled heat pump unit 10 blows out cold air through its fan. A set temperature is set for the air conditioning room 12 via the control box 13. Thermocouples measure the temperature inside the air conditioning room 12, and the temperature signal is transmitted to the control box 13. When the temperature exceeds the set value, the first electric valve 15 connected to the air conditioning room 12 opens, and the second electric valve 17 connected to the outdoor environment closes. Cold air is then blown into the air conditioning room 12 through the duct 11 and U-shaped pipe 14 for cooling. When the temperature falls below the set value, the second electric valve 17 connected to the outdoor environment opens, and the first electric valve 15 connected to the air conditioning room 12 closes. Cold air is then blown into the outdoor environment through the T-shaped pipe 16 installed on the outside of the duct 11.

[0018] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides through holes 22 on both the tee pipe 16 and the U-shaped pipe 14. A housing 19 is installed on the outer side of both the tee pipe 16 and the U-shaped pipe 14. The tee pipe 16 and the U-shaped pipe 14 are connected to the interior of the housing 19 through the through holes 22. A lead screw 21 is rotatably connected inside the housing 19, and a sliding block 20 is slidably connected inside the housing 19. The sliding block 20 is threaded onto the outer side of the lead screw 21. A sealing plate 18 is installed inside both the U-shaped pipe 14 and the tee pipe 16. The bottom end of the sliding block 20 passes through the through hole 22 and is fixedly connected to the outer wall of the sealing plate 18. The end of the lead screw 21 away from the sliding block 20 passes through the side wall of the housing 19 and extends to the outer side of the housing 19. The end of the lead screw 21 away from the sliding block 20 is fixedly connected to... When the first electric valve 15 or the second electric valve 17 needs to be inspected or maintained, turning the handle will drive the lead screw 21 to rotate. The rotation of the lead screw 21 will cause the sliding block 20 to slide inside the housing 19, thereby causing the sealing plate 18 to slide inside the tee pipe 16 or the U-shaped pipe 14, thus closing the pipe section connected to the first electric valve 15 or the second electric valve 17. At this time, the pipe sections of the tee pipe 16 and the U-shaped pipe 14 away from the electric valves are connected to the air duct 11. This method ensures that the first electric valve 15 or the second electric valve 17 can still work normally during inspection or maintenance, avoiding affecting the normal use of the device. Both ends of the lead screw 21 are rotatably connected to the inner wall of the housing 19 through bearings, and the two rotating handles are located above the tee pipe 16 and the U-shaped pipe 14, respectively.

[0019] When in use, if the first electric valve 15 or the second electric valve 17 needs to be inspected or maintained, turn the handle to drive the lead screw 21 to rotate. The rotation of the lead screw 21 causes the sliding block 20 to slide inside the housing 19, thereby causing the sealing plate 18 to slide inside the tee pipe 16 or the U-shaped pipe 14, thus sealing the pipe section connected to the first electric valve 15 or the second electric valve 17. At this time, the pipe sections of the tee pipe 16 and the U-shaped pipe 14 away from the electric valve are connected to the air duct 11. In this way, the first electric valve 15 or the second electric valve 17 can still work normally during inspection or maintenance, avoiding affecting the normal use of the device.

[0020] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
