Refrigerant and use method thereof

Abstract

The invention discloses a refrigerant. The refrigerant is a refrigerant prepared with NH4NO3, NaCO3.10H2O and CO(NH2)2 as raw materials. The three components of NH4NO3, NaCO3.10H2O and CO(NH2)2 are in collaborative compatibility, so as to generate a co-enhancing role, and a refrigeration effect is obviously superior to that of a conventional refrigerant. The invention also provides a use method of the refrigerant. A solid mixture of NH4NO3, NaCO3.10H2O and CO(NH2)2 is dissolved in an NaCl solution, the temperature of the NaCl solution can be reduced to about -12 DEG C from room temperature within 1 min, and the refrigeration time can be maintained for 8-12 min. The refrigerant has the advantages of good refrigeration effect, long refrigeration time, simple use method, convenient carrying and use, and broad market application prospects.

Description

technical field [0001] The invention belongs to the field of refrigerants, and in particular relates to a refrigerant and a usage method thereof. Background technique [0002] Refrigerant, also known as refrigerant, is the working medium of the refrigeration cycle. Existing refrigerants all utilize the heat energy absorbed or released when the physical state of the refrigerant changes, and the refrigerant is continuously cycled through the compressor while the physical state changes, so as to achieve the purpose of refrigeration, such as liquid nitrogen refrigeration. Although these refrigerants have high cooling efficiency, they are not suitable for carrying around due to the need for a compressor. If you are going out, it is very inconvenient to cool down on the road. [0003] Chinese invention patent CN 1443826A discloses a chemical refrigerant and its usage method. The refrigerant utilizes the chemically synthesized salt NH 4 NO 3 , CO(NH 2 ) 2 The solid mixture of...

Problems solved by technology

[0006] But the refrigerant refrigeration effect disclosed in this patent is poor, and refrigeration time is short

At the same time, because the refrigerant absorbs heat through a chemical reaction to achieve the purpose of refrigeration, the reaction process itself will neutralize a part of the temperature, which further reduces the refrigeration effect and refrigeration time of the refrigerant, seriously affecting the popularization and use of the refrigerant.
