Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery devices, and in particular to a waste heat recovery device in a refrigeration system. Background Technology

[0002] Cold storage, as a key link in cold chain logistics, consumes a huge amount of energy. A cold storage refrigeration system consists of a compressor, condenser, throttling device, evaporator, and auxiliary equipment. Low-temperature, low-pressure refrigerant vapor is drawn into the compressor through a suction pipe, where it is compressed to produce high-temperature, high-pressure refrigerant vapor. The condenser then condenses the refrigerant into a low-temperature, high-pressure liquid, which is further throttled by a throttling valve to become a low-temperature, low-pressure liquid refrigerant. The liquid refrigerant evaporates in the evaporator, absorbing heat to achieve refrigeration. The refrigeration capacity of cold storage systems is generally large, resulting in significant heat emissions from the condenser. Some cold storage facilities are equipped with waste heat recovery devices. These systems allow the heat emitted by the condenser to be used for other energy needs, such as hot water supply or heating, thereby improving the overall energy efficiency of the cold storage and reducing energy waste. To further improve energy efficiency and reduce operating costs, modern cold storage facilities are often equipped with advanced monitoring systems and optimized control algorithms, making the refrigeration system more efficient and stable, and enabling timely adjustments to operating parameters based on changes in the external environment.

[0003] However, in the existing technology, the condensation heat discharged by the condenser is often used to heat the water in the water tank. When the water does not flow properly in the water tank, the water temperature inside the tank is often uneven, resulting in unstable water temperature, which affects the heating efficiency of the water. The heat cannot be evenly distributed in the water, and local overheating or undercooling will occur, reducing the utilization efficiency of thermal energy, resulting in a poor user experience and defects. Utility Model Content

[0004] The purpose of this invention is to address the technical problem that in the prior art, the condensation heat emitted by the condenser is often used to heat the water in the water tank. When the water does not flow properly in the water tank, the water temperature inside the tank is often uneven, resulting in unstable water temperature, which affects the heating efficiency of the water. The heat cannot be evenly distributed in the water, resulting in local overheating or undercooling, reducing the utilization efficiency of thermal energy, and causing poor user experience. Therefore, this invention proposes a waste heat recovery device for a refrigeration system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waste heat recovery device in a refrigeration system, comprising a water storage tank, a motor fixedly connected to the lower surface of the water storage tank, an auger fixedly connected to the output end of the motor, a heat exchange tube sleeved on the outer surface of the auger, a refrigeration device body connected to both ends of the heat exchange tube, a tank lid fixedly connected to the upper surface of the water storage tank, a transmission conduit sleeved on the outer surface of the heat exchange tube, and three liquid inlet windows opened on the lower surface of the transmission conduit.

[0006] Furthermore, a viewing window is provided on the outer surface of the water storage tank, and transparent glass is embedded inside the viewing window.

[0007] Furthermore, a water level gauge is provided on the outer surface of the transparent glass.

[0008] Furthermore, the heat exchange tube is spirally wound.

[0009] Furthermore, the three liquid inlet windows are equidistantly distributed.

[0010] Furthermore, a vacuum chamber is provided inside the water storage tank.

[0011] 1. In this utility model, the water inside the water storage tank enters the transmission conduit through three inlet windows under the drive of the auger, and then exits through the upper end of the transmission conduit. When the water passes through the transmission conduit, the flowing water continuously contacts the heat exchange tube, carrying away the heat inside the heat exchange tube. The water at the bottom of the water storage tank moves upward continuously through the auger and the transmission conduit, so that the water in the lower part of the water storage tank is fully mixed with the water in the upper part, improving the water flow efficiency and heating the water inside the water storage tank evenly, avoiding unstable water temperature when using water and ensuring a good user experience.

[0012] 2. In this utility model, the working status of the internal components of the water storage tank can be observed through the transparent glass inside the viewing window, which is convenient and quick. The components can be inspected and repaired in a timely manner. The water level gauge allows for a direct view of the water level inside the storage tank, enabling timely replenishment and preventing the water level from becoming too low, which would reduce the heat that can be contained and ensure the efficiency of heat exchange. The three liquid inlet windows are evenly distributed, allowing the water at the bottom of the storage tank to enter the transmission pipe evenly, improving the mixing efficiency of the water inside the storage tank. The vacuum chamber is insulated to prevent heat loss from the inside of the storage tank and improve the heat utilization efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] like Figures 1-4 As shown, the present invention provides a technical solution: a waste heat recovery device in a refrigeration system, comprising a water storage tank 1, a motor 8 fixedly connected to the lower surface of the water storage tank 1, an auger 9 fixedly connected to the output end of the motor 8, a heat exchange tube 10 sleeved on the outer surface of the auger 9, a refrigeration device body 3 connected to both ends of the heat exchange tube 10, a tank cover 2 fixedly connected to the upper surface of the water storage tank 1, a transmission conduit 7 sleeved on the outer surface of the heat exchange tube 10, and three liquid inlet windows 11 opened on the lower surface of the transmission conduit 7.

[0021] In this embodiment, during use, the refrigerant inside the main body 3 of the refrigeration device enters the compressor, the gas is compressed, and heat is absorbed. The compressed high-temperature and high-pressure gas flows into the heat exchange tube 10. In the heat exchange tube 10, the refrigerant releases heat through heat exchange with the external water, cools and condenses into a liquid. The output end of the motor 8 drives the auger 9 to rotate inside the transmission conduit 7, so that the water inside the water storage tank 1 enters the transmission conduit 7 through the three liquid inlet windows 11 under the drive of the auger 9, and then exits through the upper end of the transmission conduit 7. When the water passes through the transmission conduit 7, the flowing water continuously contacts the heat exchange tube 10, carrying away the heat inside the heat exchange tube 10. The water in the lower part of the water storage tank 1 moves upward through the auger 9 and the transmission conduit 7, so that the water in the lower part of the water storage tank 1 is fully mixed with the water in the upper part, improving the water flow efficiency and heating the water in the water storage tank 1 evenly, avoiding unstable water temperature when using water and ensuring a good user experience. The main body 3 of the refrigeration device is a common device in daily life, and a specific model can be selected according to needs, which will not be described in detail here.

[0022] Example 2

[0023] like Figures 1-4 As shown, a viewing window 4 is provided on the outer surface of the water storage tank 1, and a transparent glass 5 is embedded inside the viewing window 4. A water level gauge 6 is provided on the outer surface of the transparent glass 5. The heat exchange pipe 10 is spirally wound, and three liquid inlet windows 11 are evenly distributed. A vacuum chamber 12 is provided inside the water storage tank 1.

[0024] In this embodiment, the working status of the internal components of the water storage tank 1 can be observed through the transparent glass 5 inside the viewing window 4, which is convenient and quick, and allows for timely maintenance of the components. The water level gauge 6 provides a direct view of the water level inside the water storage tank 1, allowing for timely replenishment and preventing the water level inside the water storage tank 1 from becoming too low, which would reduce the amount of heat that can be contained and ensure the efficiency of heat exchange. The three liquid inlet windows 11 are evenly distributed, so that the water at the bottom of the water storage tank 1 enters the transmission conduit 7 evenly, improving the mixing efficiency of the water inside the water storage tank 1. The vacuum chamber 12 is heat-insulated to prevent heat loss from the inside of the water storage tank 1 and improve the heat utilization efficiency.

[0025] Working principle: such as Figures 1-4As shown, during use, the refrigerant inside the main body 3 of the refrigeration device enters the compressor, where the gas is compressed and absorbs heat. The compressed, high-temperature, high-pressure gas flows into the heat exchange tube 10. In the heat exchange tube 10, the refrigerant releases heat through heat exchange with external water, cools, and condenses into a liquid. The output end of the motor 8 drives the auger 9 to rotate inside the transmission conduit 7, causing the water inside the water storage tank 1 to enter the transmission conduit 7 through the three liquid inlet windows 11 under the action of the auger 9, and then exit through the upper end of the transmission conduit 7. As the water passes through the transmission conduit 7, the flowing water continuously contacts the heat exchange tube 10, carrying away the heat inside the heat exchange tube 10. The water in the lower part of the water storage tank 1 passes through the auger 9 and the transmission conduit. 7 continuously moves upwards, allowing the water in the lower part of the water tank 1 to fully mix with the water in the upper part, improving the water flow efficiency and heating the water inside the water tank 1 evenly. The working status of the internal components of the water tank 1 can be observed through the transparent glass 5 inside the viewing window 4, allowing for timely maintenance of the components. The water level inside the water tank 1 can be intuitively understood through the water level gauge 6, allowing for timely replenishment and preventing the water level inside the water tank 1 from becoming too low, which would reduce the heat that can be contained and ensure the efficiency of heat exchange. The three liquid inlet windows 11 are evenly distributed, allowing the water in the lower part of the water tank 1 to enter the interior of the transmission conduit 7 evenly, improving the mixing efficiency of the water inside the water tank 1. The vacuum chamber 12 is insulated to prevent heat loss from the inside of the water tank 1.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
