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.
