Description

Technical Field

[0001] This utility model relates to the field of ice storage technology, specifically a direct expansion ice storage integrated machine. Background Technology

[0002] With industrial development and the improvement of people's material and cultural living standards, the popularity of air conditioning has increased year by year, and electricity consumption has grown rapidly. Peak electricity is in short supply, while off-peak electricity is not fully utilized. Therefore, how to transfer peak electricity demand, shift peak demand and fill valleys, balance electricity supply, and improve the effective utilization of electricity has become an important issue for many countries to address. The adoption of time-of-use pricing policies and certain incentive policies has further promoted the enthusiasm for using off-peak electricity, which has led to the attention and development of off-peak cold storage technology.

[0003] Ice storage air conditioning uses off-peak electricity at night to make ice and store it in an ice storage device. During the day, the ice melts and the stored cold energy is released to reduce the power load on the air conditioning system and the installed capacity of the air conditioning system during peak hours.

[0004] Existing ice storage technologies store cold energy by utilizing the latent heat value during ice making. However, cold energy is still lost during ice making. When dynamic ice storage is used, problems such as ice blockage of pipes and ice particles impacting water pump turbines and fans often occur, leading to reduced lifespan. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a direct expansion ice storage integrated machine to solve the technical problems of cold loss during ice making and the fact that ice blocks often clog pipes and ice particles impacting water pump turbine fans, which reduces their lifespan when dynamic ice storage is used.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a direct expansion ice storage integrated machine, including a casing, a dust filter plate installed on one side of the casing, a condenser fixedly connected to one side of the dust filter plate, the condenser being composed of multiple layers of coiled copper tubes, and a drying bottle fixedly connected to one end of the copper tube of the condenser, the drying bottle being fixedly connected to an expansion valve through the copper tube.

[0007] When the motor is powered on and starts, the gas enters the casing through the dust filter plate, passes through the condenser composed of multiple copper tubes, and is finally discharged from the casing by the fan. During this process, room temperature air enters the casing and carries away a large amount of heat as it passes through the multiple copper tubes. The room temperature air is converted into hot air and discharged, while the high temperature and high pressure gaseous refrigerant in the copper tubes dissipates a large amount of heat. The gas is cooled and converted into room temperature and high pressure liquid refrigerant, which flows through the copper tubes to the dryer bottle for filtration and dehumidification. Then, the room temperature and high pressure liquid refrigerant flows to the expansion valve, where it is throttled and converted into low temperature and low pressure gaseous refrigerant.

[0008] Furthermore, one end of the expansion valve is also connected to a copper pipe, which runs through the interior of the ice storage tank and is fixedly connected to the ice storage pipe. The ice storage pipe is located within the insulation layer and is wound around the outer wall of the ice storage chamber. A sealing cover is movably connected to the top of the ice storage chamber. The sealing cover is penetrated by multiple sets of copper pipes. A filter is fixedly connected to one end of the copper pipe, an ice crusher is fixedly connected to the middle part of the copper pipe, and a water pump is fixedly connected to the other end of the copper pipe.

[0009] By adopting the above technical solution, the low-temperature and low-pressure gaseous refrigerant is diverted through the expansion valve and transported upward through the copper pipe, passing through the outer shell of the ice storage tank and entering the insulation layer. The low-temperature and low-pressure gaseous refrigerant flows downward in the ice storage pipe, evaporating and absorbing heat. At this time, the liquid water in the ice storage chamber begins to cool down and condense until it begins to freeze. The ice-water mixture enters the pipeline through the filter. The filter isolates large ice blocks, and a small amount of ice particles mixed with water enters the pipeline and flows through the ice crusher.

[0010] Furthermore, an insulation layer is fixedly connected to the inner wall of the ice storage tank shell, and the outer wall of the insulation layer is fixedly connected to the outer wall of the ice storage cavity.

[0011] By adopting the above technical solution, the low-temperature and low-pressure gaseous refrigerant is diverted through the expansion valve and transported upward through the copper pipe, passing through the outer shell of the ice storage tank and entering the insulation layer. The copper pipes inside the insulation layer are coiled layer by layer around the outer wall of the ice storage cavity to form an ice storage pipe group.

[0012] Furthermore, the ice crusher consists of a grinding chamber, a toothed seat, and grinding teeth. The inner wall of the grinding chamber is slidably connected to the toothed seat, and multiple sets of grinding teeth are fixedly connected inside the toothed seat.

[0013] By adopting the above technical solution, the ice particles mixed with water enter the pipe and flow through the ice crusher. The ice crusher has a set of inclined grinding teeth. As the liquid flows, the grinding teeth are driven by force to rotate the tooth base in the grinding chamber, and the grinding teeth grind the large ice particles.

[0014] Furthermore, the compressor is fixed to the housing by a bracket, and an isolation plate is fixedly connected to the inner wall of the housing, which serves to divide the space.

[0015] Furthermore, a metal bracket is fixedly connected inside the housing, and multiple sets of motors are fixedly connected inside the metal bracket. Each set of motors has a fan fixedly connected to its output end, and the fan plays the role of heat dissipation and cooling.

[0016] By adopting the above technical solution, a metal bracket is installed in front of the copper tube, and two sets of fans are mounted on the metal bracket by motors. When the motors are powered on, the gas enters the casing through the dust filter plate, passes through the condenser composed of multiple layers of copper tubes, and is finally discharged from the casing by the fans. In this process, when room temperature air enters the casing and passes through multiple layers of copper tubes, it carries away a large amount of heat, and the room temperature air is converted into hot air and discharged.

[0017] Furthermore, a protective grille located in front of the fan is fixedly connected to the inner wall of the housing, and a cover plate located on the right side of the isolation plate is also fixedly connected inside the housing.

[0018] Furthermore, a copper pipe is fixedly connected to the output end of the water pump, and an evaporator is fixedly connected to the copper pipe through the casing. The evaporator plays the role of absorbing heat and delivering cold.

[0019] By adopting the above technical solution, ice water is transported to the evaporator by the action of the water pump, and the cold air on the evaporator is taken away by the external air supply device to complete the output of cold energy. After absorbing heat through the evaporator, the ice water flows back into the ice storage chamber.

[0020] In summary, the present invention has the following main advantages: The refrigerant is compressed into a high-temperature, high-pressure gas by a compressor. It is then efficiently cooled and converted into a liquid by a condenser with a dust filter. The liquid is then throttled by an expansion valve to form a low-temperature, low-pressure gas. The top-down flow design allows the low-temperature refrigerant to settle more quickly and absorb heat more fully in the ice storage tube, significantly improving ice storage efficiency. During daytime cooling, the ice-water mixture in the ice storage chamber is protected by a filter and an ice crusher, reducing damage to the water pump and extending equipment life. At the same time, it ensures that the ice-water is delivered evenly to the evaporator to stably release cooling capacity, ultimately forming a closed loop. This system has the triple advantages of energy saving, high-efficiency cold storage, and equipment protection, achieving a balance between energy saving and operational reliability.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A direct expansion ice storage integrated machine, such as Figure 1-7 As shown, the device includes a housing 1, a dust filter plate 504 is installed on one side of the housing 1, a condenser 5 is fixedly connected to one side of the dust filter plate 504, the condenser 5 is composed of multiple layers of coiled copper tubes 3, and a dryer bottle 6 is fixedly connected to one end of the copper tube 3 of the condenser 5, and an expansion valve 7 is fixedly connected to the dryer bottle 6 through the copper tube 3. When the motor 503 is powered on, the gas enters the casing 1 through the dust filter plate 504, passes through the condenser 5 composed of multiple copper tubes 3, and is finally discharged from the casing 1 by the fan 502. During this process, when the room temperature air enters the casing 1 and passes through the multiple copper tubes 3, it carries away a large amount of heat. The room temperature air is converted into hot air and discharged, while the high temperature and high pressure gaseous refrigerant in the copper tubes 3 dissipates a large amount of heat. The gas is cooled and converted into room temperature and high pressure liquid refrigerant. It flows through the copper tubes 3 and passes through the dryer bottle 6 for filtration and dehumidification. Then, the room temperature and high pressure liquid refrigerant flows to the expansion valve 7, and is converted into low temperature and low pressure gaseous refrigerant through the throttling of the expansion valve 7.

[0026] Furthermore, one end of the expansion valve 7 is also connected to a copper pipe 3, which runs through the interior of the ice storage tank shell 401 and is fixedly connected to the ice storage pipe 404. The ice storage pipe 404 is located inside the insulation layer 403 and is wound around the outer wall of the ice storage chamber 406. A sealing cover 402 is movably connected to the top of the ice storage chamber 406. The sealing cover 402 is penetrated by multiple sets of copper pipes 3. A filter 405 is fixedly connected to one end of the copper pipe 3, and an ice crusher 9 is fixedly connected to the middle part of the copper pipe 3. A water pump 10 is fixedly connected to the other end of the copper pipe 3. The low-temperature, low-pressure gaseous refrigerant is diverted through the expansion valve 7 and transported upward through the copper pipe 3, passing through the outer shell 401 of the ice storage tank and entering the insulation layer 403. The low-temperature, low-pressure gaseous refrigerant flows downward in the ice storage pipe 404, evaporating and absorbing heat. At this time, the liquid water in the ice storage chamber 406 begins to cool down and condense until it begins to freeze. The ice-water mixture enters the pipeline through the filter 405. The filter 405 isolates large ice blocks, and a small amount of ice particles mixed with water enter the pipeline and flow through the ice crusher 9.

[0027] Please see Figure 3 and Figure 6 The ice crusher 9 consists of a grinding chamber 901, a toothed seat 902, and grinding teeth 903. The toothed seat 902 is slidably connected to the inner wall of the grinding chamber 901, and multiple sets of grinding teeth 903 are fixedly connected inside the toothed seat 902. The ice particles mixed with water enter the pipe and flow through the ice crusher 9. The ice crusher 9 has a set of inclined grinding teeth 903. As the liquid flows, the grinding teeth 903 are driven by the force to rotate the tooth base 902 in the grinding chamber 901, and the grinding teeth 903 grind the large ice particles.

[0028] Please see Figure 2 and Figure 3 A metal bracket 501 is fixedly connected inside the casing 1. Multiple sets of motors 503 are fixedly connected inside the metal bracket 501. A fan 502 is fixedly connected to the output end of each set of motors 503. The fan 502 plays the role of heat dissipation and cooling. A metal bracket is installed in front of the copper pipe 3. Two sets of fans 502 are mounted on the metal bracket via motors 503. When the motors 503 are powered on, the gas enters the casing 1 through the dust filter plate 504, passes through the condenser 5 composed of multiple layers of copper pipes 3, and is finally discharged from the casing 1 by the fans 502. During this process, when the room temperature air enters the casing 1 and passes through the multiple layers of copper pipes 3, it carries away a large amount of heat, and the room temperature air is converted into hot air and discharged.

[0029] The working principle of this utility model is as follows: When the power is turned on, the compressor 2 starts and the gaseous refrigerant in the pipeline enters the compressor 2. The compressor 2 compresses the room temperature gaseous refrigerant into a high temperature and high pressure gaseous refrigerant. The high temperature and high pressure gaseous refrigerant flows through the copper pipe 3 to the condenser 5. The condenser 5 is made of multiple layers of copper pipe 3. A large area dust filter plate 504 is installed behind the copper pipe 3, and a metal bracket is installed in front of the copper pipe 3. Two sets of fans 502 are installed on the metal bracket through the motor 503. When the high-temperature and high-pressure gaseous refrigerant passes through the multi-layer copper tubes 3, the motor 503 is energized and starts. The gas enters the casing 1 through the dust filter plate 504, passes through the condenser 5 composed of the multi-layer copper tubes 3, and is finally discharged from the casing 1 by the fan 502. During this process, when the room temperature air enters the casing 1 and passes through the multi-layer copper tubes 3, it carries away a large amount of heat. The room temperature air is converted into hot air and discharged, while the high-temperature and high-pressure gaseous refrigerant in the copper tubes 3 dissipates a large amount of heat. The gas is cooled and converted into room temperature and high-pressure liquid refrigerant. It flows through the copper tubes 3 and passes through the drying bottle 6 for filtration and dehumidification. Then, the room temperature and high-pressure liquid refrigerant flows to the expansion valve 7, and is converted into low-temperature and low-pressure gaseous refrigerant through the throttling of the expansion valve 7. Low-temperature, low-pressure gaseous refrigerant is diverted through expansion valve 7 and transported upward through copper pipe 3, passing through the outer shell 401 of the ice storage tank and entering the insulation layer 403. Inside the insulation layer 403, copper pipe 3 is coiled layer by layer around the outer wall of the ice storage cavity 406 to form an ice storage pipe group 404. The low-temperature, low-pressure gaseous refrigerant flows downward in the ice storage pipe 404, evaporates and absorbs heat. At this time, the liquid water in the ice storage cavity 406 begins to cool down and condense until it begins to freeze. Because low-temperature gas settles faster than high-temperature gas, the low-temperature, low-pressure gaseous refrigerant flows faster from top to bottom, resulting in higher evaporation and heat absorption efficiency. During this process, the low-temperature, low-pressure gaseous refrigerant absorbs heat and transforms into a normal-temperature, low-pressure gaseous refrigerant, which flows out of the ice storage tank through copper pipe 3 and flows to compressor 2 for the next refrigeration cycle until the ice storage tank has completed its cold storage capacity. During daytime use, the power is turned on, energizing the water pump 10. The water pump 10 generates suction, and the ice-water mixture in the ice storage chamber 406 enters the pipeline through the filter 405. The filter 405 isolates large ice blocks, while a small amount of ice particles mixed with water enters the pipeline and flows through the ice crusher 9. The ice crusher 9 contains a set of inclined grinding teeth 903. As the liquid flows, the grinding teeth 903 are driven by force to rotate the tooth base 902 in the grinding chamber 901, grinding the large ice particles. At this time, when the ice water passes through the water pump 10, the collision of ice particles with the turbine blades of the water pump 10 is reduced, greatly increasing the service life of the water pump 10. The ice water is transported to the evaporator 8 by the water pump 10, and the cold air on the evaporator 8 is carried away by the external air supply device, completing the cold output. After absorbing heat through the evaporator 8, the ice water flows back into the ice storage chamber 406, completing one cycle.
