Description

Technical Field

[0001] This utility model relates to the technical field of absorption refrigerator core technology, specifically to an absorption refrigerator core with waste heat recovery. Background Technology

[0002] Absorption refrigerators are environmentally friendly high-tech products. Because they do not use Freon, they protect the atmospheric ozone layer. They have no compressor or any mechanical transmission parts and do not produce any noise during operation. Therefore, they are hailed by international environmental organizations as "double green environmental protection products". Their core component is the refrigeration core, which is a fully enclosed system made of steel pipes that are bent, shaped and welded together.

[0003] In existing technology, the core of an absorption refrigerator typically consists of an evaporator, an absorber, a generator, and a condenser. Ammonia water is heated and vaporized, and the vapor enters the condenser, where it is cooled and becomes liquid. However, the above method has the following drawbacks in actual use: the waste heat generated during the operation of the condenser is not easy to collect and utilize, resulting in a waste of heat energy. In addition, during the process of heating and vaporizing ammonia water in the generator, heat loss is severe, and the heating area and the contact area between the ammonia water are fixed, resulting in generally low internal heating efficiency.

[0004] Based on this, this utility model designs an absorption refrigerator core with waste heat recovery to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an absorption refrigerator core with waste heat recovery.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An absorption refrigerator core with waste heat recovery includes a generator and a condenser installed on its outside, and a recovery component. The recovery component is disposed on the outside of the condenser and is used to recover and utilize the waste heat on the condenser. The recovery component includes a cartridge and a conduit. A micro air pump is installed on the generator, and the input end of the micro air pump is connected to the cartridge through the conduit.

[0008] Furthermore, the recycling assembly also includes a sleeve and a set of drive plates disposed on its outer side. The sleeve is installed inside the generator, and an annular cover is rotatably connected to the outer side of the sleeve. The drive plates are fixedly installed to one side of the annular cover, and the side of the drive plates contacts the inner wall of the generator.

[0009] Furthermore, a heater is provided on the inner bottom wall of the generator, and the sleeve is fitted onto the outside of the heater;

[0010] Furthermore, an I-shaped rod is installed inside the annular cover, the I-shaped rod extending into the inside of the sleeve and positioned above the heater;

[0011] Furthermore, the condenser is provided with a set of heat dissipation fins inside the card box on the outside, the card box has a docking hole on one side, and the generator is provided with an exhaust pipe for connecting to the docking hole on the outside.

[0012] Furthermore, the generator is equipped with a liquid storage tank, an absorber, and an evaporator on its outer side, which, together with the generator and condenser, complete the overall process operation of the refrigerator core.

[0013] Furthermore, a set of the drive plates are evenly distributed along the axis of the sleeve, and the output end of the micro air pump is equipped with a horizontal pipe that communicates with the generator. Beneficial effects

[0014] 1. The heat energy emitted by the heat dissipation fins on the condenser is collected by the card box, and then guided into the generator through the conduit to recover and utilize the waste heat. In addition, an insulation layer is formed on the outside of the sleeve to reduce the serious heat loss during the heating and vaporization of ammonia water.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 An absorption refrigerator core with waste heat recovery includes a generator 100 and a condenser 200 installed on its outside, and a recovery component 300. The recovery component 300 is disposed on the outside of the condenser 200 and is used to recover and utilize the waste heat on the condenser 200. The recovery component 300 includes a cartridge 310 and a conduit 320. A micro air pump 110 is installed on the generator 100, and the input end of the micro air pump 110 is connected to the cartridge 310 through the conduit 320.

[0026] In this embodiment of the invention, during the operation of the refrigerator core, the generator 100 heats and vaporizes ammonia water, and then the condenser 200 condenses the high-temperature steam. Next, the recovery component 300 recovers and utilizes the heat generated during the operation of the condenser 200.

[0027] In this embodiment of the utility model, the waste heat generated during the operation of the condenser 200 is collected by the card box 310, and then the hot air is discharged through the duct 320 for use during the start-up of the micro air pump 110.

[0028] In some embodiments, such as Figure 4As shown, in a preferred embodiment of the present invention, the recycling assembly 300 further includes a sleeve 330 and a set of drive plates 340 disposed on its outer side. The sleeve 330 is installed inside the generator 100, and an annular cover 331 is rotatably connected to the outer side of the sleeve 330. The drive plate 340 is fixedly installed on one side of the annular cover 331, and the side of the drive plate 340 contacts the inner wall of the generator 100.

[0029] Hot air is introduced into the generator 100 and blows the corresponding drive plate 340, causing the drive plate 340 to move the annular cover 331. After entering the generator 100, the hot air will be on the outside of the sleeve 330. Using its own heat, it forms a heat insulation layer on the outside of the sleeve 330, thereby reducing the rapid heat loss during the heating and vaporization of ammonia water and ensuring the heating efficiency of ammonia water.

[0030] In this embodiment of the present invention, a heater 120 is provided on the inner bottom wall of the generator 100, and a sleeve 330 is sleeved on the outside of the heater 120. By operating the heater 120, the ammonia water in the sleeve 330 can be heated and vaporized.

[0031] In this embodiment of the invention, an I-shaped rod 332 is installed inside the annular cover 331. The I-shaped rod 332 extends into the sleeve 330 and is located above the heater 120. After the hot air is introduced into the generator 100, the drive plate 340 will drive the annular cover 331 and the I-shaped rod 332 to rotate. During the rotation of the I-shaped rod 332, ammonia water can be driven to flow, thereby changing the contact area between the ammonia water and the heater 120, thereby improving the heating effect.

[0032] In this embodiment of the invention, a set of heat dissipation fins 210 located inside the card box 310 are provided on the outside of the condenser 200. A docking hole 311 is provided on one side of the card box 310. An exhaust pipe 130 for connecting with the docking hole 311 is installed on the outside of the generator 100. Heat is introduced into the card box 310 by the heat dissipation fins 210. After the hot air is introduced into the generator 100 and used, the hot air after use is guided back into the card box 310 along the docking hole 311 by the exhaust pipe 130, mixed with subsequent heat energy, and recycled to ensure heat energy intensity and save energy.

[0033] In this embodiment of the utility model, a liquid storage tank 140, an absorber 150 and an evaporator 160 are respectively provided on the outside of the generator 100. By adopting the corresponding arrangement of the liquid storage tank 140, the absorber 150 and the evaporator 160, the complete process in the core system can be completed, such as the storage of ammonia, the collection and reflux of ammonia after liquefaction, and the evaporator 160 absorbing heat when the ammonia evaporates to produce a cooling effect.

[0034] It should be noted that the above-mentioned liquid storage tank 140, absorber 150 and evaporator 160 are all commonly used equipment in existing refrigerator cores. The supporting technology is a mature existing technology, so the pipe connections and position distribution between its various components will not be described in detail.

[0035] In this embodiment of the utility model, a set of drive plates 340 are evenly distributed along the axis of the sleeve 330, and the output end of the micro air pump 110 is equipped with a horizontal pipe that communicates with the generator 100. By using the horizontal pipe, the gas drawn by the conduit 320 can be introduced into the generator 100 along the horizontal pipe.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
