Aluminum Air Conditioner Evaporator

Air Conditioner Cooling Evaporator

According to the operating pressure, the aluminum air conditioner evaporator is divided into three types: normal pressure, pressurized and decompressed. 

According to the movement status of the solution in the evaporator, there are: 

① circulation type. The boiling solution passes through the heating surface multiple times in the heating chamber, such as central circulation tube type, hanging basket type, external heating type, Levin type and forced circulation type, etc. 

② One-way type. The boiling solution passes through the heating surface once in the heating chamber, and the concentrated liquid is discharged immediately without circulating flow, such as rising film type, falling film type, stirred film type and centrifugal film type, etc. 

③ direct contact type. The heating medium is in direct contact with the solution to transfer heat, such as a submerged combustion evaporator. During the operation of the evaporation device, a large amount of heating steam is consumed. In order to save heating steam, a multi-effect evaporation device and a vapor recompression evaporator can be used. Evaporators are widely used in chemical industry, light industry and other departments.

Classification of aluminum air conditioner evaporator:

1. Divided by evaporation method:
Natural evaporation: That is, the solution evaporates at a temperature lower than the boiling point, such as seawater drying salt. In this case, the solvent vaporization rate is low because the solvent only vaporizes on the surface of the solution.
Boiling evaporation: Heating the solution to the boiling point to make it evaporate in the boiling state. Industrial evaporation operations are basically of this type.
2. According to the heating method:
Direct heat source heating is an evaporation process in which the fuel is mixed with air, and the high-temperature flame and smoke generated by the combustion are directly sprayed into the evaporated solution through the nozzle to heat the solution and vaporize the solvent.
The indirect heat source heats the vessel walls to the evaporated solution. That is, the heat transfer process carried out in the dividing wall heat exchanger.
3. According to operating pressure:
It can be divided into atmospheric pressure, pressurized and reduced pressure (vacuum) evaporation operations. Obviously, for heat-sensitive materials, such as antibiotic solutions, fruit juices, etc., it should be carried out under reduced pressure. High-viscosity materials should be heated by a pressurized high-temperature heat source (such as heat transfer oil, molten salt, etc.) for evaporation
4. According to the effect number:
Can be divided into single-effect and multi-effect evaporation. If the secondary steam generated by evaporation is directly condensed and no longer used, it is called single-effect evaporation. If the secondary steam is used as the next-effect heating steam, and multiple evaporators are connected in series, the evaporation process is multi-effect evaporation.

Industrial application of aluminum air conditioner evaporator:

Aluminum air conditioner evaporator is a unit operation that uses heating to heat a solution containing a non-volatile solute to a boiling state, so that part of the solvent is vaporized and removed, thereby increasing the concentration of the solute in the solvent. The application of evaporation operation in industrial production has the following occasions:
1. Concentrate dilute solution to directly produce products or reprocess concentrated solution (such as cooling and crystallization) to produce solid products, such as the concentration of electrolytic caustic soda, the concentration of sugar aqueous solution and the concentration of various fruit juices, etc.
2. Concentrate the solution and recover the solvent at the same time, such as the concentrated debenzene of the organophosphorus pesticide benzene solution, the evaporation of the alcohol leachate in the production of traditional Chinese medicine, etc.
3. In order to obtain pure solvents, such as seawater desalination, etc.

In short, in the chemical industry, food industry, pharmaceutical and other industries, evaporation operation is widely used.
