Description

Technical Field

[0001] The present invention relates to the technical field of integrated heat exchange, and more specifically to an integrated heat exchange system device coupling a heat pump and a natural cold source. Background Art

[0002] A heat pump is a device that extracts heat from a low-temperature environment and transfers it to a high-temperature environment by inputting a small amount of electrical energy and using a compression and expansion cycle. A heat pump can usually perform both refrigeration and heating functions simultaneously, has a high energy efficiency ratio, and can operate efficiently under different environmental conditions. The working principle of a heat pump is based on a thermodynamic cycle and usually proceeds through four basic steps: evaporation, compression, condensation, and expansion. In a heat pump system, a low-temperature refrigerant is compressed into a high-temperature and high-pressure gas by a compressor, and then the heat is released through a condenser; in the evaporator, the low-temperature refrigerant absorbs heat and evaporates, transferring the heat from the low-temperature environment to the high-temperature environment during the cycle.

[0003] According to the invention patent with the Chinese patent publication number CN102434929B, titled an energy-saving dual-temperature air-conditioning system coupling solar energy, natural cold energy, and off-peak electricity, it is specifically described as an energy-saving dual-temperature air-conditioning system coupling natural cold energy and off-peak electricity, that is, an air-conditioning system that preferentially uses solar energy, natural cold energy, and off-peak electricity for energy storage. The technical key point is that a phase change energy storage device is added on the basis of the existing air-conditioning structure, that is, natural cold sources can be used for cold storage in summer, and solar energy can be used for heat storage in winter. It realizes that the indoor thermal environment is cooled by natural cold sources and heat pump units in summer and heated by solar energy and heat pump units in winter, making greater use of new clean and renewable energy sources and reducing the power consumption of the air conditioner.

[0004] However, the existing integrated heat exchange system devices coupling a heat pump and a natural cold source have the following deficiencies: 1. Traditional filter screen cleaning and replacement methods: In traditional heat exchange equipment, filter screens are usually used to remove impurities in the cold source water to prevent them from entering the heat exchange system. However, traditional filter screen systems are usually maintained by manual or timed cleaning methods. It is necessary to regularly stop the machine, disassemble the filter screen, and clean the accumulated impurities in it. This method usually requires shutdown operations, resulting in the reduction of the operating efficiency of the equipment. During the shutdown period, the entire system is in a stopped state and cannot perform heat exchange work normally, causing productivity losses. Whether it is manual or timed cleaning, it is necessary to stop the machine for cleaning, wasting a large amount of operating time and reducing the efficiency of the equipment. Due to the lack of real-time monitoring, the filter screen may not be cleaned in time when it is blocked, resulting in a long-term decline in the operating efficiency of the equipment and even possible failures. Moreover, the traditional method cannot avoid the problem of filter screen blockage. Especially when the impurity content in the water is relatively high, the filter screen is prone to accumulating dirt, resulting in poor water flow and reducing the heat exchange effect.

[0005] 2. Traditional heat pump systems are usually designed to be fixedly installed in outdoor environments. Although this design can ensure the normal operation of the heat pump in many cases, it also brings some potential problems. Especially when encountering extreme weather conditions, such as excessive rainfall, the heat pump is prone to face the following problems. Traditional heat pumps are usually directly exposed to the outdoor environment. Especially in rainy seasons or areas with more precipitation, when a large amount of rainwater accumulates around the heat pump, the equipment may not be able to drain the water in time, and the rainwater may enter the interior of the heat pump. Especially when the waterproof design is not perfect or the drainage system fails to remove the accumulated water in time, there are usually complex electrical components inside the heat pump system. If rainwater seeps in, it will cause the electrical part to be affected by moisture, which may lead to serious problems such as short circuits, failures, and even fires. The accumulation of rainwater may also cause some other mechanical failures. Especially if the accumulated water cannot be drained smoothly, the accumulated water may directly affect the mechanical components of the heat pump, resulting in the equipment being unable to work properly.

[0006] Therefore, we propose an integrated heat exchange system device that couples a heat pump with a natural cold source to solve the problems mentioned above. Summary of the Invention

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the cold source auxiliary filtering mechanism and the precise control of the first rack and the second rack provided in the present invention, the valve body can be alternately opened and closed. The realization of this mechanism effectively avoids the blockage of the filter net and greatly improves the filtering efficiency. The first rack and the second rack drive the toothed ring to rotate, so that the valve is alternately opened and closed, thus ensuring the continuous smoothness of the filter net and preventing the filter net from being blocked due to excessive accumulation of deposits. The user can replace and clean the filter net without shutting down the machine, thus realizing the efficient operation of the equipment. In addition, the sundries around the filter net are effectively removed under the action of the cleaning brush, further reducing the impurities in the cold source water and reducing the burden on the heat exchanger. Through this mechanism, the equipment can not only maintain a high filtering efficiency, but also effectively extend the service life of the heat exchanger, avoid the decrease in heat exchange efficiency caused by the accumulation of impurities, and ensure the long-term stable operation of the equipment.

[0019] 2. Through the cold source auxiliary filtering mechanism provided in the present invention, a push-button alarm is set. Through the cooperation of the trigger rod and the alarm, it is ensured that when the filter net is blocked or other abnormalities occur, an alarm can be issued in time. This alarm not only improves the self-protection ability of the equipment, but also helps the user to master the equipment status at any time during the operation of the equipment. When the filter net is blocked or other problems occur, the trigger rod will transmit the pressure to the push-button alarm through the sliding mechanism, thus issuing an alarm to remind the user to take measures in time. The design of the push-button alarm ensures the timely replacement or cleaning of the filter net, effectively avoids the decrease in equipment performance caused by excessive blockage, and prevents the equipment from causing a wider range of failures due to the damage of the filter net. This alarm system provides all-round protection for the equipment, avoids the decrease in the operation efficiency of the heat pump and natural cold source coupled integrated heat exchange equipment body caused by the blockage of the filter net, thus ensuring the long-term stable operation of the equipment. At the same time, this alarm can avoid greater damage caused by negligence or failure to handle problems in time, reduce the maintenance cost and improve the use reliability of the equipment.

[0020] 3. In the present invention, through the provided lifting mechanism, the design of the lifting mechanism adopts a combination of a humidity switch and an electric lifting rod. When there is excessive water accumulation at the bottom of the integrated heat exchange equipment body where the heat pump is coupled with the natural cold source, the humidity switch will sense the change in the bottom water level and promptly trigger the electric lifting rod to work. The electric lifting rod can lift the support base within an extremely short time, raising the integrated heat exchange equipment body where the heat pump is coupled with the natural cold source, ensuring that the bottom of the integrated heat exchange equipment body where the heat pump is coupled with the natural cold source does not directly contact the accumulated water. This automatic lifting mechanism effectively reduces the entry of moisture into the integrated heat exchange equipment body where the heat pump is coupled with the natural cold source, especially preventing the moisture of electronic components and other sensitive parts, and avoiding failures and damages caused by moisture penetration. Through this mechanism, the service life of the equipment is significantly extended. Especially in a humid environment, the equipment can better avoid corrosion and wear caused by water sources. In addition, shock pads are designed at the bottom end of the support base, which can effectively absorb vibrations and impacts during the lifting process, reducing unnecessary force transmission during mechanical movement, and further avoiding equipment damage caused by the lifting action. Through this precisely controlled lifting mechanism, the equipment can automatically adapt to environmental changes, avoiding incorrect operations that may be caused by manual intervention. Especially in a humid environment, the induction of the humidity switch can ensure that the equipment is lifted in a timely manner when the moisture at the bottom of the equipment exceeds the standard, avoiding electrical and mechanical failures caused by the equipment's long-term contact with water sources.

Sleeve barrels 222 are fixedly sleeved on the middle parts of the two filter pipes 205. Preloading springs 221 are fixedly connected to the bottoms of the two sleeve barrels 222. The bottoms of the two preloading springs 221 are respectively fixedly connected to the tops of the two installation collar rings 212. Trigger rods 220 are fixedly connected to the outer walls of the two installation collar rings 212. Press-type alarms 219 are provided at the tops of the two trigger rods 220. Extension plates 218 are fixedly connected to the tops of the two press-type alarms 219. One ends of the two extension plates 218 are respectively fixedly connected to the outer walls of the two filter pipes 205. A cold source reservoir body 3 is provided on one side of the integrated heat exchange equipment body 1 of the heat pump and natural cold source coupling. Guide rails 207 are slidably connected to the outsides of a rack one 208 and a rack two 213. The two guide rails 207 are fixedly connected to the inner wall of the cold source reservoir body 3. A connecting member 211 is fixedly connected between the rack one 208 and the rack two 213. A moving support 226 is fixedly connected to the back of the connecting member 211. The bottom end of the motor 217 is fixedly connected with a base 9. One end of the base 9 is fixedly connected to the inner wall of the cold source reservoir body 3. The output end of the motor 217 is fixedly connected with a lead screw 225. The middle part of the lead screw 225 is threadedly connected with the moving support 226. A limiting rod 224 is fixedly connected to the inside of the base 9. The middle part of the limiting rod 224 is slidably connected with the moving support 226. One end of the limiting rod 224 is fixedly connected with a support plate 8. The support plate 8 is fixedly connected to the inner wall of the cold source reservoir body 3. Two connecting plates 214 are fixedly connected to the bottom end of the rack two 213. One ends of the two connecting plates 214 are respectively fixedly connected with opening stabilizing plates 215. Cleaning brushes 216 are snap-fitted to the tops of the two opening stabilizing plates 215.

[0027] The effects achieved by the entire Example 1 are as follows: When the integrated heat exchange equipment body 1 with the heat pump coupled to the natural cold source is started, the transfer pump 7 sends the water in the cold source reservoir through the filter pipe 205 into the tee pipe 202, and then guides it to the heat exchanger part of the equipment through the transfer pipe 6. The user can start the motor 217, drive the movement of the lead screw 225 through the motor 217, drive the movement of the movable support 226 and the connecting member 211, and then drive the movement of the first rack 208 and the second rack 213. The first rack 208 and the second rack 213 respectively drive the rotation of the corresponding gear rings, thereby alternately opening and closing the valve body 206, avoiding the blockage of the filter net 223 and improving the filtration efficiency. Through this mechanism, the user can replace and clean the filter net 223 without stopping the machine. The movement of the second rack 213 will also drive the movement of the connecting plate 214 and the opening stabilizing plate 215, thereby pushing the cleaning brush 216 to clean the filter net 223 and the sundries around it, further reducing the impurities in the cold source water and extending the service life of the heat exchanger. When the filter net 223 is blocked, the transfer pump 7 generates negative pressure to help remove the blocked filter net 223. The movement of the filter net 223 drives the filter sleeve 222 to slide along the filter pipe 205. The preloading spring 221 at the top of the filter sleeve 222 prevents the slight deviation of the filter net 223 when the transfer pump 7 sends water. When the filter sleeve 222 moves to a certain height, the trigger rod 220 will press the push-button alarm 219 to timely remind the user to replace the filter net 223.

[0028] It should be noted that the opening stabilizing plate 215 is designed with openings, which can avoid the situation that when the opening stabilizing plate 215 blocks the filter net 223, the filter net 223 can still contact the water inside the cold source reservoir body 3. And when the filter net 223 is blocked, the transfer pump 7 will generate negative pressure to help remove the blocked filter net 223. The movement of the filter net 223 will drive the filter sleeve 222 to slide along the filter pipe 205, and the preloading spring 221 at the top of the filter sleeve 222 can prevent the slight deviation of the filter net 223 when the transfer pump 7 sends water. Through the precise control of the first rack 208 and the second rack 213, the valve body 206 can be alternately opened and closed, effectively avoiding the blockage of the filter net 223, improving the smoothness of the water flow, thereby improving the filtration efficiency and extending the service life of the filter net 223. The trigger rod 220 and the push-button alarm 219 are used in cooperation to ensure that the user is timely reminded when there is a problem with the filter net 223, avoiding the risk of affecting the equipment performance due to the damage or blockage of the filter net 223. The timely alarm reminder helps to avoid equipment damage caused by excessive blockage. The specific model of the push-button alarm 219 is Honeywell WLD2-ALERT.

[0029] Example 2, according to Figure 1 - Figure 2As shown, there is a lifting mechanism 4, which includes an electric lifting rod 401, a humidity switch 406, and a support base 403. Electric lifting rods 401 are connected to the four corners at the bottom end of the support base 403. The humidity switch 406 is electrically connected to the four electric lifting rods 401. The bottom end of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source is fixedly connected to the top end of the support base 403. A partition 404 is fixedly connected to the bottom end of the support base 403. A regulating rod 405 is connected to the middle of the partition 404. The bottom end of the regulating rod 405 is fixedly connected to the top end of the humidity switch 406. Shock pads 402 are fixedly connected to the bottom ends of the four electric lifting rods 401.

[0030] The effect achieved by the entire embodiment 2 is as follows: The lifting mechanism 4 consists of an electric lifting rod 401, a humidity switch 406, and a support base 403. When there is too much water accumulation at the bottom of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source, it can automatically activate the protection mechanism. When the water accumulation at the bottom of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source reaches a certain height, the humidity switch 406 will sense the moisture and trigger the electric lifting rod 401 to work. The electric lifting rod 401 will quickly lift the support base 403, lifting the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source, avoiding the direct contact of the bottom of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source with the water source. At this time, the support base 403 is connected to the electric lifting rods 401 through four corners to ensure the stability of the lifting process. A partition 404 and shock pads 402 are installed at the bottom end of the support base 403 to reduce the vibration and impact generated by the lifting of the equipment, ensuring that the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source is not damaged during the lifting process. Through the induction of the humidity switch 406, when there is too much water accumulation, the electric lifting rod 401 is started in time to lift the equipment, avoiding the direct contact of the equipment bottom with the water source, thereby reducing the entry of moisture into the equipment interior and preventing the internal components of the equipment from getting damp, especially the electronic components are not easily damaged. Since the equipment is isolated from the water source, the corrosion and wear that may be caused by long-term contact with the water source are avoided, significantly extending the service life of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source. Shock pads 402 are fixedly connected to the bottom ends of the four electric lifting rods 401, effectively absorbing vibration during the lifting process and reducing the mechanical impact generated by the lifting action, ensuring the stable operation of the equipment, and reducing the noise generated during the operation of the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source. The entire lifting process is automatically controlled by the humidity switch 406 without manual intervention, ensuring that the integrated heat exchange equipment body 1 of the heat pump coupled with the natural cold source can be automatically lifted in time when there is too much water accumulation, improving the self-protection ability and operation convenience of the equipment.

[0031] It should be noted that the specific models of the humidity switch 406 and the electric lifting rod 401 are Honeywell WLD2 and LINAK LA31 respectively.

[0032] The working principle of the whole device is as follows: By setting a cold source auxiliary filtering device, when the integrated heat exchange device body 1 of the heat pump coupled with the natural cold source starts, the transfer pump 7 sends the water inside the cold source reservoir into the filter pipe 205, and then enters the three-way pipe 202 through the filter pipe 205. The water is sent into the transfer pipe 6 under the action of the transfer pump 7. The transfer pipe 6 guides the water to the heat exchanger at the temple of the integrated heat exchange device body 1 of the heat pump coupled with the natural cold source. The user can start the motor 217, and the output end of the motor 217 drives the lead screw 225 to move. The lead screw 225 drives the moving support 226 to move. The movement of the moving support 226 will drive the connecting piece 211 to move, and then drive the movement of the first rack 208 and the second rack 213. The first rack 208 and the second rack 213 respectively drive the rotation of the two toothed rings. During the movement of the first rack 208 and the second rack 213, through the connecting piece 211, the first rack 208 drives the corresponding toothed ring to rotate clockwise, while the second rack 213 drives the corresponding toothed ring to rotate counterclockwise. In this way, the two valve handles 209 can rotate alternately, so as to alternately open and close the corresponding valve body 206. This design can effectively avoid the blockage of the filter screen 223. At the same time, when the user needs to replace the filter screen 223, the integrated heat exchange device body 1 of the heat pump coupled with the natural cold source does not need to stop. During the movement of the second rack 213, it will also drive the connecting plate 214 to move, and the connecting plate 214 will then drive the perforated stabilizing plate 215 to move. The perforated stabilizing plate 215 pushes the cleaning brush 216 to clean the filter screen 223 and the sundries around it, so as to avoid the blockage of the filter screen 223. The cleaning of the filter screen 223 can effectively reduce the impurities in the cold source and extend the service life of the heat exchanger. When the filter screen 223 is blocked, a negative pressure will be formed inside the transfer pump 7 to help the blocked filter screen 223 move. The movement of the filter screen 223 drives the filter sleeve 222 to move along the filter pipe 205. The preloading spring 221 at the top of the filter sleeve 222 prevents the slight deviation of the filter screen 223 caused by the water supply of the transfer pump 7. When the filter sleeve 222 moves to a certain height, the trigger rod 220 will squeeze the pressing alarm 219 to timely remind the user to replace the filter screen 223, so as not to affect the operation efficiency of the integrated heat exchange device body 1 of the heat pump coupled with the natural cold source. When replacing the filter screen 223, the user can turn off the motor 217 to open one of the valve bodies 206 and replace the filter screen 223 at the bottom end of the filter pipe 205 connected to the other valve body 206. Through the set lifting mechanism 4, when there is too much accumulated water at the bottom of the integrated heat exchange device body 1 of the heat pump coupled with the natural cold source, one end of the humidity switch 406 will be inserted into the water, and the electric lifting rod 401 will be started. The electric lifting rod 401 will lift the support base 403 to avoid the device being contaminated by water, reduce the water entering the device interior, and avoid damage to the electronic components.
