Multifunctional cold storage preservation storehouse

Abstract

The invention discloses a multifunctional cold storage preservation storehouse. The multifunctional cold storage preservation storehouse comprises a storehouse body and an intelligent control system which is connected with the storehouse body and controls the storehouse body. The storehouse body is provided with a liquid nitrogen adjusting system and a humidity adjusting system. The liquid nitrogen adjusting system comprises a refrigerant tank installed at one end outside the storehouse body, a temperature sensor, an oxygen concentration sensor, a liquid nitrogen conveying pipeline and an atomization nozzle. The temperature sensor, the oxygen concentration sensor, the liquid nitrogen conveying pipeline and the atomization nozzle are arranged in the storehouse body. The humidity adjusting system comprises a humidity sensor and a humidifier. The multifunctional cold storage preservation storehouse has the main advantages that the application occasions are wide, and the structure is simple and convenient; liquid nitrogen serves as a refrigerant, so that no additional resources need to be consumed for heat exchange, equipment is simple, and fast cooling can be achieved; and data in the storehouse can be monitored in real time, the refrigerant tank can be locked in all directions and can be replaced conveniently, all indexes of the storehouse body can be monitored automatically and precisely, and data are recorded, saved, printed and transmitted.

Description

technical field [0001] The invention relates to the technical field of refrigeration and preservation, in particular to a long-distance transport refrigeration and preservation technology integrating temperature control, oxygen regulation and humidity regulation. Background technique [0002] Refrigeration technology preservation is very important in cold chain logistics transportation. The mainstream refrigerated and fresh-keeping transportation includes refrigerated trucks and mobile fresh-keeping cabins. [0003] Existing refrigerated vehicles are basically composed of special-purpose vehicle chassis, heat-insulating and heat-insulating compartment refrigerating units, temperature recorders in the compartment and other components. [0004] The existing mechanical refrigeration units are generally divided into two types, independent units and non-independent units. The difference is that the independent units completely use another unit to generate power for maintenance w...

AI Technical Summary

Problems solved by technology

[0005] 1. The unit has many operating parts and takes up a lot of space;

[0006] 2. The refrigeration is slow, and the cooling capacity per unit mass is relatively small;

[0007] 3. Only the temperature can be controlled, but the gas composition of the compartment cannot be controlled, which may easily cause excessive water vapor;

[0008] 4. The cost is high, maintenance is difficult, and professional flight attendants are required for maintenance;

[0009] 5. Refrigerants are harmful; easy to leak; not environmentally friendly and not very safe;

[0010] 6. Rely on external power supply or other energy sources, which consume a lot of energy;

[0011] 7. Loud noise

[0014] 1. The control precision is low, the temperature adjustment range is large, and the adjustment is not sensitive;

[0015] 2. No humidity and oxygen concentration detection, no necessary data for reasonable storage of vegetables and fruits

[0018] 1. The cooling capacity per unit mass is relatively small;

[0019] 2. Rely on power supply and consume a lot of energy;

[0020] 3. The structure is complex, the unit has many moving parts, and the noise is large;

[0021] 4. The refrigerant is harmful (ODP, GWP control); easy to leak; low safety;

[0022] 5. It is easy to get water and cause freezing to block the pipeline

[0024] 1. The control precision is low, the temperature adjustment range is large, the adjustment is not sensitive, and it is not conducive to energy saving;

[0025] 2. Without humidity detection, it is impossible to obtain the necessary data for reasonable refrigeration and preservation of vegetables, fruits or other fresh products, and it cannot automatically record, save, print, etc. the data

[0026] From the above, it can be seen that in the prior art, it is necessary to design the equipment for the refrigerated truck and the mobile fresh-keeping compartment separately, and there are problems such as complex structure, low cost, poor refrigeration and fresh-keeping, which lead to long-distance transportation limitations, and are not conducive to economic and industrial development.
