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.

Embodiment 1

[0028] 40g NH 4 NO 3 , 35g NaCO 3 10H 2 O, 25g CO(NH 2 ) 2 Mix to form a solid mixture, then dissolve in 75g of NaCl solution (the mass percentage of NaCl is 10%), and mix well to realize refrigerant refrigeration.

[0029] The temperature of the refrigerant described in Example 1 drops from normal temperature to -15° C. within 1 minute. When the timer reaches -15°C, it will take 9 minutes to return to 0°C without taking any heat preservation measures. The cooling time of the refrigerant in this embodiment can be maintained for 12 minutes.

[0030] The refrigerant described in Example 1 is used to refrigerate 250ml of water, and the temperature of the water can be reduced from normal temperature to 8°C within 1.5 minutes; after 15 minutes, the temperature of the water can still be maintained at 12°C.

Embodiment 2

[0032] 80g NH 4 NO 3 , 10g NaCO 3 10H 2 O, 10g CO(NH 2 ) 2 Mix to form a solid mixture, then dissolve in 75g NaCl solution (the mass percentage of NaCl is 15%), and mix well to realize refrigerant refrigeration.

[0033] The temperature of the refrigerant described in Example 2 drops from normal temperature to -12°C within 1 minute, and the refrigeration time can be maintained for 9 minutes.

[0034] The refrigerant described in Example 2 is used to refrigerate 250ml of water, and the temperature of the water can be reduced from normal temperature to 12°C within 1.5 minutes; after 15 minutes, the temperature of the water can be maintained at 15°C.

Embodiment 3

[0036] 30g NH 4 NO 3 , 50g NaCO 3 10H 2 O, 10g CO(NH 2 ) 2 Mix to form a solid mixture, then dissolve in 120 g of NaCl solution (the mass percentage of NaCl is 5%), and mix well to realize refrigerant refrigeration.

[0037] The temperature of the refrigerant described in Example 3 drops from normal temperature to -12°C within 1 minute, and the refrigeration time can be maintained for 8 minutes.

[0038] The refrigerant described in Example 3 is used to refrigerate 250ml of water, and the temperature of the water can be reduced from normal temperature to 12°C within 1.5 minutes; after 15 minutes, the temperature of the water can be maintained at 16°C.

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...
