What is the difference between evaporator and condenser?What's the difference between an evaporator and a condenser?Recently, some people often ask these questions. Now, the difference between evaporator and condenser will give you a simple introduction.
Roughly speaking, evaporators and condensers, both heat transfer devices, are indistinguishable.But there is a difference between the evaporator and the condenser in terms of use. The condenser is used to emit heat, and the evaporator is used to absorb heat.
This is only from a rough point of view, to understand the difference between evaporator and condenser, or need to understand what is evaporator, what is condenser.
It has been said that evaporators and condensers are heat exchange equipment. What is heat exchange equipment?
Heat exchange equipment refers to the need to have two or more than two kinds of fluids with different temperatures, and the heat transfer equipment between the fluids is called heat exchange equipment, so the evaporator and condenser are heat exchange equipment.
What is an evaporator?
Evaporator is a unit operation that uses the method of heating to heat the solution containing different substances and non-volatile solutes to boiling state, so that part of the solvent vaporizes and is removed at the same time, thus improving the concentration of the solution in the solvent.
Evaporator is mainly composed of two parts: heating chamber and evaporation chamber.The heating chamber provides the heat needed for the evaporation of the liquid and promotes the boiling and vaporization of the liquid. The evaporation chamber is a part that makes the gas-liquid two phases completely separate.
What is a condenser?
The condenser is a part of the refrigeration system and also a part of the whole evaporator system. The condenser is mainly used to discharge heat. It can convert gas or steam into liquid and release heat in a very fast way.
The working process of condenser is an exothermic process. In the process of evaporation, the device that transforms steam into liquid is also called condenser.All condensers operate by taking away the heat of a gas or steam.
The difference between evaporator and condenser
From the above concept of evaporator and condenser, it can be seen that the difference between the two is that the condenser is mainly used to emit heat, while the evaporator is used to absorb heat.
The difference between the evaporator and the condenser is mainly the different working forms. The evaporator is the medium that absorbs heat to vaporize and absorb external heat, while the condenser is the equipment that reduces the temperature and liquefies the medium and releases heat externally.
The evaporator and the condenser are also different in structure.
In the evaporator design, the type selection design should be carried out according to the evaporation capacity and evaporating materials of the whole system.
In the design of condenser, shunt road should be used. The entrances of different roads should be as close as possible, the exits should also be as close as possible, and the inlet and outlet should be as far away as possible, so as to avoid the loss of part of heat transfer due to reheating and the uneven distribution of flow.
In the actual design, if the shunts are more than two, the centralized liquid divider and collector should be used to make the flow between different flow paths even as far as possible.It is better that the tubes of different flow paths should be the same, and should flow evenly through the windward side and leeward side to make the heat transfer uniform.
The above is a brief introduction of the difference between evaporator and condenser. The difference between evaporator and condenser is that one is an exothermic device, and the other is an endothermic device.
