Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, refrigeration and ice storage, and in particular to an ice making and ice-removing device in a dynamic ice making and ice storage system. Background Art

[0002] Ice storage is a technology that uses off-peak electricity to store cold energy in ice, and then releases the stored cold energy during peak electricity demand periods to provide cooling services. At present, ice storage technology has been widely used in air-conditioning systems. The application of ice storage technology in the field of air conditioning is of great significance for balancing the load of the power grid and reducing the operating costs of air-conditioning systems in places where peak and valley electricity prices are implemented.

[0003] At present, ice storage technology in the air-conditioning field is developing rapidly, widely used, increasingly mature, and diversified in system types. Ice storage technology has also undergone an iterative development process from static ice storage to dynamic ice storage, and then to ice slurry ice storage.

[0004] Static ice making means that ice preparation and melting are carried out at the same location. The ice storage equipment and ice making components are integrated structures. Common forms include external coil ice storage system and packaged ice cold storage system. In the external coil ice storage system, the ice-making coil is set in an ice storage tank (tank) filled with water. The refrigerant or refrigerant solution circulates in the coil, absorbing the heat of the water in the tank (tank), causing the water temperature to drop and forming an ice layer on the outer surface of the coil. The packaged ice cold storage system is to encapsulate the cold storage medium (such as water or organic salt solution) in a specific container, and use the refrigerant produced by the refrigeration machine to flow through these containers, so that the cold storage medium (such as water or organic salt solution) in the container is frozen to store cold.

[0005] Dynamic ice making means that the preparation and storage of ice are not in the same place, and the ice maker and ice storage device are relatively independent. Common forms include ice flake sliding type and ice crystal type. In this system, the ice maker makes water into ice flakes or ice crystals, and then sends them to the ice storage device for storage. Ice slurry storage is also a form of dynamic ice making. It first lowers the water temperature to below the freezing point to form small particles of ice crystals, and at the same time makes the generated ice crystals mix with water in the ice slurry generating device to form ice slurry, and then the ice slurry is transported to the ice storage device through the conveying system for storage.

[0006] The dynamic ice making and ice storage system realizes the timely separation of ice flakes and ice making devices, which not only improves the ice melting and heat exchange efficiency because the separated ice flakes have a larger surface area, but also controls the thickness of the ice flakes due to the timely separation of the ice flakes and the ice making device, which greatly improves the working efficiency of the ice making device. However, as for the ice making devices of the current dynamic ice making and ice storage system, the common ice flake sliding mode generally adopts a method similar to hot fluorine defrosting to send hot fluorine into the ice making machine evaporator to melt the ice on the evaporator tube wall (or plate surface) so that it falls off and separates. As a result, not only the refrigeration system is complicated, but also the efficiency of the system is seriously affected due to interruptions and reversals in the ice making process.

[0007] To this end, an ice making and ice-removing device in a dynamic ice making and ice storage system is proposed, which will effectively solve the above problems and thus improve the system working efficiency while simplifying the refrigeration system. Summary of the invention

[0029] The ice making and de-icing device in the present application can be operated independently in the form of a single unit, or can be operated jointly in the form of a combination of multiple units, so as to meet the needs of different ice making and ice storage loads.

[0030] Working principle of embodiment 1: A folding corrugated evaporator is made of high-strength elastomer material and assisted by a first de-icing linkage mechanism for ice making and de-icing, including a corrugated evaporator 4, a first liquid supply pipe 5, a first air return pipe 6, an evaporator fixing steel frame 2, a first de-icing linkage mechanism 7, a base 1, a guiding mechanism 3, etc. The upper flange of the high-strength elastomer corrugated body of the evaporator is connected to the screw rod of the first de-icing linkage mechanism 7, and the guiding mechanism 3 connecting the upper and lower flanges of the evaporator is provided with a limiting nut which can be telescopically moved within a certain range. Driven by a motor, the upper flange of the evaporator is pressed and pulled by the screw rod, so that the corrugated evaporator can be telescopically moved within a certain range within the limit distance. When the ice-making and de-icing device reaches the set ice-making time or the ice layer thickness on the outer wall of the evaporator reaches the set thickness, the sensor transmits a signal to the first de-icing linkage device 7, and the first de-icing linkage device 7 starts to move up and down within a limited range, and the screw rod presses and pulls the high-strength elastic folded corrugated body of the evaporator to repeatedly expand and contract within a certain range, so that the ice layer on its surface is broken and separated from the high-strength elastic folded corrugated body of the evaporator, and then the broken and detached crushed ice flows to the ice storage place along with the water flow; Working principle of the second embodiment: The sleeve evaporator with elastic spiral parts is used and assisted by the second deicing linkage mechanism 12 for ice making and deicing. The device includes the sleeve evaporator 9 with elastic spiral parts, the second liquid supply pipe 10, the second air return pipe 11, the evaporator fixing steel frame 2, the second deicing linkage mechanism 12, the base 1, etc. The second deicing linkage mechanism 12 is composed of a screw drive speed reduction mechanism 16, an equidistant stud 15, and a transition connecting plate 14.

When the ice-making and de-icing device reaches the set ice-making time or the ice layer thickness on the outer wall of the evaporator reaches the set thickness, the sensor transmits the signal to the second de-icing linkage device, which compresses the elastic spiral parts close to the outer wall of the evaporator when it moves downward, so that the elastic spiral parts scrape off the ice layer on the outer wall of the casing during compression and then reset. This process can be repeated many times until the ice layer is completely separated from the outer wall of the casing, and then the broken and detached ice flows to the ice storage area with the water flow.
