What Are the Refrigerant, Surfactant, and Corrosion Inhibitor for LiBr Absorption Chiller?
Hope Deepblue is the largest manufacturer of refrigeration and heating equipment in southwest China. The main products are LiBr absorption chiller and heat pump. LiBr absorption chillers can refrigerate by different heat sources, such as hot water, steam, flue gas, etc. LiBr absorption heat pump can convert low temperature heat source into high temperature heat source.
1.Refrigerant - Water
The refrigerant water from the condenser absorbs the heat of the chilled water in the tube of the evaporator and reduces the temperature of the chilled water to the setting value. The cooling water is used to reduce the temperature of the medium in the absorber and condenser, and it is heated up and connected to the cooling water circulation system, and returns to the LiBr absorption units for recycling after cooling down.
2.Surfactant - Isooctanol
Hope Deepblue is the largest manufacturer of refrigeration and heating equipment in Southwest China, specializing in LiBr absorption chillers and heat pumps. These systems utilize various heat sources, such as hot water, steam, and flue gas, for refrigeration. Additionally, LiBr absorption heat pumps can convert low-temperature heat into high-temperature heat.
- Refrigerant - Water
In the LiBr absorption chiller, the refrigerant, water, absorbs heat from the chilled water in the evaporator tubes, reducing the chilled water's temperature to the desired value. Cooling water is used to lower the temperature of the medium in both the absorber and condenser. After being heated, this water circulates through the cooling system and returns to the LiBr absorption units for reuse after cooling. - Surfactant - Isooctanol
Surfactants, such as isooctanol, are added to LiBr solutions to improve the heat exchange efficiency of the equipment. These substances significantly reduce surface tension. Isooctanol is a colorless liquid with a pungent odor at atmospheric pressure and has low solubility in water. Studies have shown that adding isooctanol can increase the cooling capacity by approximately 10-15%.
- Corrosion Inhibitor - Lithium Molybdate
LiBr solution has inherent corrosive properties, and the presence of air inside the LiBr absorption unit can exacerbate the corrosion of the solution on the unit's components. To mitigate this, a corrosion inhibitor like lithium molybdate is used. Lithium molybdate forms a protective film on the metal surfaces through a chemical reaction, effectively reducing or preventing the metal from being exposed to oxygen and minimizing corrosion.
