Problems solved by technology

Salt with a particle size of 10 to 50 mesh, that is, a size of 0.3 to 2 mm, such a particle size of salt can evenly cover the surface of block ice to promote the smooth melting of ice, and different refrigeration can be achieved according to the number of salt particles As a result, it solves the problem that the temperature of ice and salt mixed refrigeration changes too fast and is not smooth, which leads to the destruction of food nutrition, etc., and it is convenient to control the temperature drop rate of refrigeration

preparation example Construction

[0015] In the preparation method of the refrigerant, when the weight ratio of ice and salt in the refrigerant is determined, the mesh size of the salt particles is adjusted to make the temperature change stable, and the temperature change can be controlled by adding salt particles of different particle sizes. Gentle, low temperature duration is not the same. Here is an example to illustrate the refrigeration effect when the weight ratio of ice and salt is 2 to 5 to 1, as described in Table 1, including Examples 1 to 8.

[0016] Table 1: Examples 1 to 8, the ratio of ice and salt, the salt particle size, the minimum temperature, the speed of reaching the minimum temperature, and the duration of low temperature are as follows:

Embodiment 9

[0019] See figure 1 , a freezer filled with the refrigerant prepared by the refrigerant preparation method of the present invention, the freezer includes a box body 1, an insulation cover 2 and an insulation layer 3, the inner diameter of the box body 1 is 7 cm, and the height is 18 cm. centimeter; the thickness of insulation layer 3 is 7 millimeters, is also provided with a freezing interlayer 4 in insulation layer 3, and the thickness of freezing interlayer 4 is 1.3 centimetres, and described freezing interlayer 4 is used for filling refrigerant, and the salt described in this example It is granular, which controls the mesh size of salt particles and promotes the smooth melting of ice salt.

Abstract

The invention relates to a preparation method of a refrigerant and a freezer filled with the refrigerant. The lowering speed of the refrigeration temperature is controlled through the regulation of salt granularity in the components of ice and salt in the refrigerant. The invention also provides the freezer filled with the refrigerant. The freezer comprises a box body provided with a heat insulation layer and a heat insulation cover, wherein, the heat insulation layer is further provided with a freezing interlayer; and the freezing interlayer is used for being filled with the refrigerant. Thesurfaces of blocks of ice are covered with salt particles to facilitate steady melting of the ice and the salt, and different refrigeration effects are achieved according to different mesh numbers ofthe salt particles, thereby solving the problem that the nutrients of food are destroyed by over-quick and unsmooth ice-salt refrigeration temperature change; and the product is light in weight, is easy to popularize in the society, and is simple and practical.

Description

technical field [0001] The invention relates to the field of civil refrigeration, in particular to a refrigerant and refrigeration equipment using the refrigerant. Background technique [0002] Nowadays, as the climate continues to warm, various refrigeration products are widely used. For example, refrigerators are commonly used refrigeration products. Using refrigerant, it is impossible to reduce its size and weight enough, that is, the car refrigerator, its use cost is also high, and it is inconvenient to use. Only a few car owners use it. At the same time, when there is no power supply, ordinary refrigerators are Unable to work, can not meet the needs of most people, the fusion of ice and salt can be refrigerated, but the temperature of ice and salt mixed refrigeration changes too fast, and the temperature change is very unstable, which leads to the destruction of food nutrition, that is, the refrigeration cannot be controlled The rate of temperature drop during the proc...
