Embodiment Construction

[0006] The refrigerant used in its cold refrigerator and cooler is preferably mixed with ice and salt, with a ratio of 3:0.5 to 1.5 (weight), and the temperature in the adiabatic shell can generally be reduced to about -17--18°C and 8°C, which is higher than the current one. With refrigerators and freezers, the temperature can be lowered by -1-2°C and 3-7°C respectively. The cold refrigerator is equipped with 46.5 catties of refrigerant at a time, and can be used for about half a month in May, June, September, and October, and about 13 days in July and August. It can be used for about 21 days in April and November, and it can be used for more than one month in January-March and December (the above all refer to North my country in China). With 66.6 catties of refrigerant at a time, the drink cooler can cool 100 catties of beverages for about four days. The refrigerant of small-scale cold storage (storage capacity 4-12 tons) preferably utilizes ice and calcium chloride to mix, ...

Abstract

The present invention relates to a chemical refrigeration equipment. It is made by utilizing the principle of that using ice and edible salt or mixing ice and calcium chloride or mixing ice, edible and calcium chloride to form refrigerant and using said refrigerant to refrigerate food and adding heat-insulating shell body and container in which the refrigerant can be held.

Description

Technical field: [0001] The invention relates to a chemical refrigeration device. Background technique: [0002] The current refrigerators, cold drink machines and small cold storages use electric energy for refrigeration, which not only consumes a lot of electric energy but also is limited by the power supply, so it is not only expensive to use but also limited in scope of use, so it cannot be used in a suitable environment. Seasons are widely used. Invention content: [0003] The object of the present invention is to provide a chemical refrigeration device. [0004] The present invention is realized in this way: utilize refrigerant to refrigerate, and refrigerant is based on ice (H2O), adds appropriate amount of salt (NaCI) or calcium chloride (CaCI2), and the cooperation of refrigerant is: first crush ice into Small pieces, then add salt or calcium chloride and mix evenly into the refrigerant tank, then put the refrigerant tank inside the insulated shell, and then clo...
