Description

Technical Field

[0001] The invention belongs to the technical field of refrigeration units, and in particular relates to an energy-saving refrigeration unit with rapid heat dissipation. Background Art

[0002] A refrigeration unit is a device that transfers heat from a low-temperature object to a high-temperature environment through artificial refrigeration, thereby cooling a specific space or object. For example, a fast heat-dissipating energy-saving refrigeration unit is proposed in patent announcement number CN221840227U.

[0003] Refrigeration units are mainly composed of four basic components: compressor, condenser, expansion valve and evaporator. Among them, water-cooled condenser is a commonly used heat exchange equipment in refrigeration system. It uses water as cooling medium to transfer the heat released by refrigerant in the condensation process to cooling water, so that the refrigerant is condensed from gas to liquid. However, after long-term use of water-cooled condenser, calcium, magnesium ions and impurities in cooling water are easy to form scale on the inner wall of heat exchange tube, such as calcium carbonate, calcium sulfate and other precipitation, which will hinder heat transfer and reduce heat exchange efficiency. After long-term accumulation, the condensation temperature and pressure of the refrigeration system will increase, and the cooling capacity will decrease. Therefore, operators are required to clean the scale on the inner wall of heat exchange tube regularly. However, due to the different concentrations of calcium and magnesium ions in different types of cooling water, when using cooling water with high concentrations of calcium and magnesium ions, thicker scale will be attached to the inner wall of heat exchange pipe before the set cleaning cycle. If the operator does not handle it in time, it will seriously affect the refrigeration effect of condenser.

While ensuring that the scale inside the heat exchange pipe is cleaned up, it also avoids the problem of excessive concentration of the cleaning liquid, which causes waste of cleaning liquid; A cleaning assembly 19 is arranged on the upper side wall of the base plate 1 and is used to clean the scale in the internal pipes of the condenser 2. The cleaning assembly 19 includes a mixing box 191 and a liquid storage box 192 fixedly connected to the upper side wall of the base plate 1.

[0022] A recovery box 28 is fixedly connected to the upper side wall of the base plate 1, and the recovery box 28 is located in front of the condenser 2. A high-pressure air pump 29 is fixedly connected to the upper side wall of the recovery box 28. The outlet end of the high-pressure air pump 29 is fixedly connected to an outlet pipe 30, and a mechanical one-way valve 31 is provided in the outlet pipe 30. The rear end of the outlet pipe 30 is connected to the feed pipe 3, and the pipe wall of the discharge pipe 5 is fixedly connected to a recovery pipe 32, and a regulating valve 33 is provided in the recovery pipe 32. The front end of the recovery pipe 32 is connected to the recovery box 28, so that the gas inside the condenser 2 can be recovered into the recovery box 28 for storage.

[0023] The upper side wall of the base plate 1 is fixedly connected with a connection cover 38, and the upper side wall of the connection cover 38 is fixedly connected with multiple fans 39. When the condenser 2 is working, the heat generated by the condenser 2 can be quickly discharged in time, thereby improving the working efficiency of the condenser 2 and reducing the energy consumption of the condenser 2.

[0024] The upper side wall of the mixing box 191 is fixedly connected with a stirring motor 40 , the output end of which passes through the mixing barrel and is fixedly connected with a stirring frame 41 , which can stir and mix the cleaning liquid and the aqueous solution transported to the inside of the mixing box 191 .

[0025] The operating principle of the present invention is now described as follows: when scale adheres to the inner wall of the heat exchange pipe inside the condenser 2, the heat exchange efficiency of the condenser 2 will be greatly reduced. After the PLC controller 7 detects this situation through the temperature sensor inside the condenser 2, it will control the detection pump 10 to work during the operation of the condenser 2. The detection pump 10 transports the condensed water discharged from the inside of the condenser 2 to the drain pipe 82. After the detection pump 10 has worked for five seconds, the PLC controller 7 will control the detection pump 10 to stop working. At this time, the cooling water inside the detection cylinder 81 will cover the two conductive blocks 12. When the detection pump 10 stops working, the PLC controller 7 will stop working. The PLC controller 7 will control the conductive block 12 on the left to be electrically connected to the external power supply. When the scale in the heat exchange pipe inside the condenser 2 is more, the concentration of calcium ions and magnesium ions in the cooling water will be relatively high. The calcium ions and magnesium ions will increase the conductivity of the cooling water. The external power supply will be transmitted to the conductive block 12 on the right through the conductive block 12 on the left, and the conductive block 12 on the right is electrically connected to the electromagnetic block 14. The external current will be transmitted to the electromagnetic block 14, so that the electromagnetic block 14 is energized to generate magnetic force. The electromagnetic block 14 will attract the permanent magnet block 16 to move. When the conductive block 12 on the left of the PLC controller 7 is connected to the external power supply, the PLC controller 7 The regulating valve 45 will also be controlled to open, and the permanent magnet block 16 will drive the piston seat 15 and the conductive frame 17 to move to the right together. Under the action of air pressure, the external gas will enter the horizontal box 13 through the air inlet pipe 44, so that the conductive frame 17 and the resistor plate 18 are in contact, and the conductive frame 17 is electrically connected to the external power supply, and the right end of the resistor plate 18 is electrically connected to the PLC controller 7. When the concentration of magnesium ions and calcium ions in the cooling water is higher, the conductive performance of the cooling water is better, so that the current intensity delivered to the electromagnetic block 14 is greater, and the magnetic attraction generated by the electromagnetic block 14 is also greater, and the electromagnetic block 14 attracts the piston seat 15 and the conductive frame 17 to move to the right. The farther away, the conductive frame 17 and the resistor plate 18 are in contact near the right end, so that the resistance on the circuit connected to the PLC controller 7 becomes smaller. Under the condition that the external voltage remains unchanged, the current signal strength transmitted to the PLC controller 7 is greater, and after the regulating valve 45 is opened for ten seconds, the PLC controller 7 will control the regulating valve 45 to close, and control the left conductive block 12 to be disconnected from the external power supply, so that the conductive frame 17 and the resistor plate 18 maintain a relatively fixed position. At this time, the PLC controller 7 will receive the current signal of the temperature, and the PLC controller 7 will prepare the cleaning liquid of appropriate concentration according to the magnitude of the current signal strength; After receiving different current signal strengths, the PLC controller 7 will control the metering pump 20 to work for different times. For example, after the PLC controller 7 receives a 2 mA current signal, the PLC controller 7 will control the metering pump 20 to work for twenty seconds, and the metering pump 20 will deliver fifty milliliters of concentrated cleaning agent to the mixing box 191, and the external pump assembly will deliver a fixed amount of aqueous solution to the mixing box 191 through the water injection pipe 21. Then the PLC controller 7 controls the stirring motor 40 to work, and the stirring motor 40 will drive the stirring frame 41 to rotate, and the cleaning agent and the aqueous solution are mixed by the stirring frame 41. Then the PLC controller 7 controls the electromagnetic valve 42 inside the feed pipe 3 and the discharge pipe 5 to close, and controls the regulating valve 33 to open, and then controls the high-pressure air pump 29 to work. The high-pressure air pump 29 delivers external gas to the feed pipe 3, and uses the external gas to deliver the cooling water inside the condenser 2 to the recovery box 28 for storage through the recovery pipe 32. After the high-pressure air pump 29 works for one minute, the remaining cooling water inside the condenser 2 will be completely cleaned up; Then the PLC controller 7 controls the high-pressure air pump 29 to stop working, and controls the regulating valve 33 to close, and then the PLC controller 7 controls the small electric push rods 242 on the left and right sides to work, and the small electric push rods 242 on both sides will drive the sealing plate 25 and the mesh plate 26 to move downward to the set position, and then the PLC controller 7 first controls the waterproof electric clamp on the surface of the right mesh plate 26 to release the sponge ball 27, and controls the left flushing pump 22 to work, and the left flushing pump 22 transports the cleaning liquid in the mixing box 191 to the condenser 2 through the feed pipe 3, and the condenser 2 is cleaned. The scale on the inside is flushed, and the flushed liquid will flow back to the mixing box 191 through the flushing pump 22 on the right (both flushing pumps 22 are centrifugal pumps. When the flushing pumps 22 are not powered on, the impellers no longer rotate and cannot provide power for the unidirectional flow of the liquid. When the hydraulic pressure at the outlet of the flushing pump 22 is greater than the hydraulic pressure at the inlet, the cleaning liquid will flow in the reverse direction, and a valve is provided at the outlet of the flushing pump 22. When the condenser 2 is working and the high-pressure air pump 29 is working, the valve is in a closed state. When the two flushing pumps 22 start flushing, the valve is in an open state). After the cleaning liquid contacts the sponge ball 27, the sponge ball 27 will hinder the flow of the cleaning liquid under the obstruction of the right mesh plate 26, thereby increasing the pressure of the left flushing pump 22 when it is working. When the PLC controller 7 detects this situation through the left hydraulic sensor 23, it will control the left flushing pump 22 to stop working and control the right flushing pump 22 to work. The right flushing pump 22 transports the cleaning liquid inside the mixing box 191 to the discharge pipe 5 for backwashing, and the cleaning liquid will drive the sponge ball 27 to move together, and the sponge ball 27 is used to scrape and clean the scale inside the pipeline. Similarly, when the sponge ball 27 contacts the mesh plate 26 on the left, the PLC controller 7 will control the right flushing pump 22 to stop working and control the left flushing pump 22 to work. After the flushing pumps 22 on both sides have worked back and forth for ten minutes, the scale inside the condenser 2 will be cleaned up, and the PLC controller 7 will control the flushing pumps 22 on both sides to stop working, and control the valves at the liquid outlet of the flushing pumps 22 to close. Then the PLC controller 7 controls the regulating valve 33 to open, and controls the high-pressure air pump 29 to work, and transports the remaining cleaning liquid inside the condenser 2 to the recovery box 28 for storage and treatment.
