Problems solved by technology

Usually, the front of the medicine refrigerator is made of transparent material, and in order to prevent condensation on the surface of the refrigerator, electric heating or other heating measures are generally required. The machine starts frequently, or the temperature inside the refrigerator is too high to protect the compressor

Embodiment 1

[0029] An appropriate amount of tetrabutylammonium bromide aqueous solution with a mass concentration of 10% is injected into the cold accumulator 10, and the mass fraction of the aqueous solution is 5% of nano Cu particles. The temperature of the refrigerator is set at 4° C., and the compressor 15 starts refrigeration. When the temperature of the refrigerator reaches 3°C, the compressor stops working. When the temperature of the refrigerator is below 5°C, the tetrabutylammonium bromide aqueous solution containing Cu particles undergoes a phase transition and crystallizes, releasing heat. After the compressor stops working, the temperature in the refrigerator gradually rises. When the temperature in the refrigerator reaches 5.9°C, the solid phase change in the regenerator decomposes and absorbs heat, the temperature rise rate in the refrigerator decreases, and the temperature in the refrigerator reaches 7°C. The compressor starts to refrigerate, and the above process is repea...

Embodiment 2

[0031] An appropriate amount of tetrabutylammonium chloride aqueous solution with a mass concentration of 15% is injected into the cold storage 10, and the mass fraction of the aqueous solution is 8% of nano-CuO particles. Set the temperature of the refrigerator to be 9° C., and the compressor 15 starts refrigeration. When the refrigerator temperature reached 8°C, the compressor 15 stopped working. When the temperature of the refrigerator is below 9°C, the tetrabutylammonium chloride aqueous solution containing CuO particles undergoes a phase transition and crystallizes, releasing heat. After the compressor 15 stops working, the temperature in the refrigerator gradually rises. When the temperature in the refrigerator reaches 10.2°C, the solid phase change in the regenerator 10 decomposes to absorb heat, the temperature rise rate in the refrigerator decreases, and the temperature in the refrigerator reaches 11°C. °C, the compressor 15 is started for refrigeration, and the abov...

Abstract

Provided is an energy storage type drug refrigerator. The energy storage type drug refrigerator mainly comprises a shell, an inner container and a door. The side, opposite to the door, of the inner container serves as the inner side of the inner container, the side, opposite to the shell, of the inner container serves as the outer side of the inner container, the inner side of the inner container is provided with a regenerator, the regenerator is arranged at the junction position of an air duct and the shell, and energy storage materials are arranged in the regenerator. The energy storage materials in the regenerator release heat to perform phase transition (the energy storage materials are changed from liquid into solid) in the cooling process of the refrigerator, the energy storage materials in the regenerator absorb heat to perform phase transition (the energy storage materials are changed from solid into liquid) in the heating process of the refrigerator, the rising speed of the temperature of the refrigerator is lowered, and the start frequency of a compressor is reduced so as to protect the compressor.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a medicine cold storage device. Background technique [0002] The progress of society and the improvement of people's living standards have put forward higher requirements for the preservation of medicines. Because medicines go through several different links from production to distributors, and then to patients, each link takes time. The quality of medicines is closely related to the storage time, and also depends on the environmental temperature conditions in which the medicines are stored. The medicine refrigerator is to provide a suitable temperature environment for the preservation of medicines by means of artificial refrigeration, so as to ensure that the medicines maintain their due medical effects within the specified validity period. [0003] At present, the medicine refrigerators on the market mainly adopt the ordinary single-stage compression refrigeration method. In order to stabil...
