Embodiment 1

[0015] The additive used when making ice slurry by using the refrigerant HCFC-123 is a compound mixed solution composed of sodium lauryl sulfate and glycerol, wherein sodium lauryl sulfate accounts for the total amount of the compound mixed solution 2%, and glycerol accounts for 98% of the compound mixed solution total amount.

[0016] A small sample test was carried out in the laboratory to prepare ice slurry. Such as figure 1 As shown, there is 1000 milliliters of water in container 3, 20 milliliters of brine HCFC-123 solution at -10°C in container 2, and 10 milliliters of brine in container 1. Additives used.

[0017] The additives used in the preparation of ice slurry by using the brine HCFC-123 in the container 1 and the brine HCFC-123 solution in the container 2 are added to the water in the container 3 to obtain a mixed solution.

[0018] After the mixed solution is fully stirred by the agitator 5, a soft and fluffy ice slurry 4 with excellent fluidity is generated, ...

Embodiment 2

[0020] The additive used when making ice slurry by utilizing the refrigerant carrier HCFC123 is a compound mixed solution composed of sodium lauryl sulfate and glycerin, wherein sodium lauryl sulfate accounts for the total amount of the compound mixed solution 3wt%, and glycerol accounts for 97wt% of the compound mixed solution total amount. All the other are with embodiment 1. The ice slurry produced by using this additive in a small sample test in the laboratory has an ice content rate of 73%.

Embodiment 3

[0022] The additive used when making ice slurry by utilizing the refrigerant carrier HCFC123 is a compound mixed solution composed of sodium lauryl sulfate and glycerin, wherein sodium lauryl sulfate accounts for the total amount of the compound mixed solution 5wt% of glycerol accounts for 96wt% of the compound mixed solution total amount. All the other are with embodiment 1. The ice slurry produced by using this additive in a small sample test in the laboratory has an ice content rate of 70%.

Abstract

The invention relates to an addition agent, in particular to an addition agent used for ice slurry production, and in particular to an addition agent used when HCFC-123 cool-carrying agent is used for producing ice slurry. The addition agent used when HCFC-123 cool-carrying agent is used for producing ice slurry is characterized in that the addition agent is a compound and mixed solution configured of sodium lauryl sulfate and glycerol, wherein the sodium lauryl sulfate occupies 1.4wt percent to 5.7wt percent of the total the compound and mixed solution, and the glycerol occupies 98.6wt percent to 94.3wt percent of the total compound and mixed solution. After the addition agent is added during the process that ice slurry is produced by HCFC-123, the produced ice slurry is soft and fluffy and has good liquidity and high ice packing factor (about 70 percent); after the ice slurry is formed and melted, the cool-carrying agent can be separated out from the ice slurry and the solution obtained after ice slurry is melted, and the second production for ice slurry can be performed circularly and conveniently.

Description

technical field [0001] The invention relates to an additive, in particular to an additive for preparing ice slurry, in particular to an additive used for preparing ice slurry by using a brine agent HCFC-123. Background technique [0002] In order to ensure the efficient, reliable and safe operation of the refrigeration cycle, ice-melting cycle and ice-making cycle of the cold storage air-conditioning device, avoid the phenomenon of blocking the ice-making system and the heat exchange channel at the user end, and ensure the normal operation of the system, it is required to be used in the cold storage air-conditioning device The ice slurry has a high ice content and good fluidity, and requires that the brine can be separated from the ice slurry and the solution obtained after the ice slurry is melted after the ice slurry is formed and melted. [0003] Generally, the ice particles of the ice slurry prepared by using brine have a tendency to coalesce. The coalescence of ice par...
