How to to make evaporator and condenser According to the compressor cooling capacity?
Compressor cooling capacity = evaporator cooling capacity
Condenser heat dissipation = compressor capacity + compressor shaft power
Evaporator is an important part of the four major refrigeration components. The low-temperature condensation "liquid" body passes through the evaporator and exchanges heat with the outside air. The "gas" heat is absorbed to achieve the cooling effect.
It mainly consists of heating chamber and evaporation chamber. The heating chamber supplies the liquid with the heat required for evaporation, which promotes the boiling of the liquid. The evaporation chamber completely separates the gas and liquid phases. The vapor generated in the heating chamber has a large amount of liquid bubbles. After reaching the evaporation chamber in a larger space, these liquids can be separated from the vapor by the action of self-condensing or demisters. The demister is usually placed on top of the evaporation chamber.
The evaporator is divided into three types according to the operating pressure: normal pressure, pressure and decompression. According to the movement of the solution in the evaporator can be divided into three kinds:
1. Cycle type
The boiling solution passes through the heating surface multiple times in the heating chamber, such as a central circulation tube type, a suspended basket type, an external heating type, a Leven type, and a forced circulation type.
2. Single-pass type
The boiling solution passes through the heating surface once in the heating chamber without circulating, ie the concentrated solution is discharged, such as a rising film type, a falling film type, a stirring film type, and a centrifugal film type.
3. Direct contact type
The heating medium is in direct contact with the solution for heat transfer, such as submerged combustion evaporators. In 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 steam re-compression evaporator may be used. Evaporators are widely used in chemical and light industries.
Condenser, The components of the refrigeration system, which converts gas or vapor into liquid, transfer the heat from the pipe to the air near the pipe in a rapid manner. The condenser on most cars is installed in front of the tank. The power plant uses many condensers to condense the steam exiting the turbine. A condenser is used in a refrigeration plant to condense refrigeration vapors such as ammonia and freon. In the petrochemical industry, condensers are used to condense hydrocarbons and other chemical vapors. In distillation, the device that turns the vapor into a liquid is called a condenser. All the condensers operate by taking away the heat of the gas or steam.
