Description

Technical Field

[0001] The present invention relates to the technical field of micro-freezing cold storage, and particularly to a micro-freezing cold storage and its control system. Background Art

[0002] Cold storages are mainly used for the freezing and refrigeration of foods. Through artificial refrigeration, a certain low temperature is maintained indoors. The walls, floors and ceilings of cold storages are all covered with a certain thickness of heat-insulating and heat-preserving materials to reduce heat transfer from the outside. To reduce the absorption of solar radiation energy, the outer wall surface of cold storages is generally painted white or light-colored. Therefore, the construction of cold storages is different from that of general industrial and civil buildings and has its unique structure. The construction of cold storages should prevent the diffusion of water vapor and the penetration of air. When outdoor air invades, it increases the cooling consumption of the cold storage and also brings in moisture. The condensation of moisture causes damage to the heat-insulating structure due to freezing and dampness. Therefore, a moisture-proof and heat-insulating layer should be set to make the cold storage have good airtightness and moisture-proof and vapor-barrier properties.

[0003] However, the existing micro-freezing cold storages have a single structure, insufficient functions, are not concise enough during installation, cannot be conveniently moved, and the internal materials cannot be classified for freezing. Therefore, they do not meet the existing requirements. For this reason, we propose a micro-freezing cold storage. Summary of the Invention

[0004] The purpose of the present invention is to provide a micro-freezing cold storage and its control system to solve the problems of the micro-freezing cold storage in the above-mentioned background art, such as single structure, insufficient functions, not being concise enough during installation, not being able to be conveniently moved, and the internal materials not being able to be classified for freezing.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A micro-freezing cold storage and its control system, including a cold storage, a cold water pool is installed below the cold storage, a hot water pool is installed on the other side of the cold water pool, cold source air ducts and heat source air ducts are installed inside both the cold water pool and the hot water pool, one ends of the cold source air ducts and the heat source air ducts are provided with main pipelines, and five heat exchange tube rows are arranged on the upper end surface of the main pipelines;

[0006] A second connecting pipe is installed at the lower end of the main pipe. A regulating valve is installed at the other end of each heat exchange row pipe. A third connecting pipe is provided at the other end of the cold source air duct. A first flow dividing valve is installed on the upper end surface of the third connecting pipe. A fifth connecting pipe is provided at the other end of the heat source air duct. A second flow dividing valve is installed on the upper end surface of the fifth connecting pipe. The pipeline between the first flow dividing valve and the second flow dividing valve is connected to the second connecting pipe through a power pump. An evaporator is installed inside the cold water tank, and a condenser is installed inside the hot water tank. The evaporator and the condenser are connected through a throttle valve and a fourth connecting pipe. A top row pipe is installed at the upper end of the fourth connecting pipe, and the top row pipe extends to the ceiling of the cold storage. The heat dissipation row pipe in the hot water tank is connected to other heat-using devices of the user. Three-way valves are installed at both ends of the top row pipe. A compressor is installed on the pipeline between the outlet of the evaporator and the inlet of the condenser. A throttle valve is installed on the pipeline between the inlet of the evaporator and the outlet of the condenser.

[0007] A control system for a slightly frozen cold storage includes a temperature regulation mechanism and a control mechanism for the slightly frozen cold storage;

[0008] Temperature regulation mechanism for the slightly frozen cold storage: The evaporator (cold source) of the compressor is immersed in the cold water tank, and the cold source air duct of the cold storage is also immersed in the cold water tank. When the first flow dividing valve is open and the second flow dividing valve is closed, and the power pump is in the starting state, the air flow is in the cold cycle state, that is, a refrigeration cycle is formed through the cold source air duct, the first flow dividing valve, the power pump, five regulating valves and five cold row pipes. The five refrigeration row pipes are distributed on the four walls and the ceiling of the cold storage. The regulating valves are used during the commissioning of the cold storage to make the temperatures in all directions of the cold storage balanced by adjusting their opening degrees. The refrigeration cycle is adopted when the outdoor temperature is higher than the set temperature of the cold storage;

[0009] The top row pipe heat source of the compressor is immersed in the warm water tank, and the heat source air duct of the cold storage is also immersed in the hot water tank.

The heating cycle is used when the outdoor temperature is lower than the set temperature of the cold storage;

[0010] The three-way valve is used when switching the refrigeration mechanism. When the three-way valve opens the cold source air duct, the evaporator serves as the refrigeration output of the compressor, causing the aqueous solution in the cold water tank to freeze. When the three-way valve opens the top row pipe, the refrigeration of the compressor is directly output to the top row pipe on the top of the cold storage, thereby serving as a strong cooling mode.

Then, hook the four hooks 5 with a crane, lift the box body 3, and move it to the upper end face of the base fixing mechanism 1. At this time, the support arm 104 is in an elevation angle state. Slowly lower the box body 3 so that the inner wall of the end angle fixing clip 107 clamps on the four end angles of the lower end face of the box body 3.

And when the base fixing mechanism 1 is fixed on a truck, the device can also be moved. When adding materials, the feeding plate 308 needs to be moved out, and then the sealed partition door 305 is placed obliquely in the card slot on the upper end face of the feeding plate 308, dividing the feeding plate 308 into three areas, enabling the device to classify and freeze the materials to meet the special freezing requirements of meat or vegetables. Place the materials separately on the upper end face of the feeding plate 308. Then, start the motor inside the motor gearbox 303, drive the screw 307 to rotate through gear meshing. The screw 307 moves left and right, causing the feeding plate 308 to move into the storage bin 302. After completion, the operator then straightens the sealed partition door 305, forming a sealed space between each partition bin 304 through the transverse groove. And when additional materials need to be added later, the operation can be achieved through the sealed door 6. Through this mechanism, the functions of feeding and installation of the device can be realized, and the internal space is divided into three separate spaces, enabling the device to classify and freeze and distinguish the temperatures of each space.
