What is the difference between an evaporator and a condenser? What is the difference between an evaporator and a condenser? Roughly speaking, the evaporator and the condenser are both heat exchange equipment and there is no difference. However, there is a difference between an evaporator and a condenser in terms of use. The condenser is used to discharge heat, and the evaporator is used to absorb heat.
This is just from a rough perspective. To understand the difference between an evaporator and a condenser, you still need to understand what is an evaporator and what is a condenser.
What is an evaporator?
Evaporator is a unit operation that uses heating to heat solutions containing different substances and non-volatile solutes to a boiling state, so that part of the solvent is vaporized and removed at the same time, thereby increasing the concentration of the solution in the solvent.
The evaporator is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the heat required for the evaporation of the liquid to promote the boiling and vaporization of the liquid. The evaporation chamber is a component that completely separates the gas and liquid phases.
What is a condenser?
The condenser is a part of the refrigeration system and a part of the entire evaporator system. The condenser is mainly used to discharge heat. It can convert gas or steam into liquid, and release heat in a fast way.
The working process of the condenser is an exothermic process. During the evaporation process, the device that converts the vapor into a liquid is also called a condenser. All condensers operate by removing heat from the gas or steam.
Difference Between Evaporator and Condenser
From the above concepts of evaporator and condenser, it can be seen that the difference between the two is that the condenser is mainly used to discharge heat, while the evaporator is used to absorb heat.
The difference between the evaporator and the condenser is mainly in the form of work. The evaporator is a medium that absorbs heat for vaporization and absorbs external heat, while the condenser is a device that cools and liquefies the medium and releases heat to the outside.
Evaporators and condensers are also structurally different.
In the design of the evaporator, the type selection and design should be carried out according to the evaporation capacity and evaporation materials of the whole system.
In the design of the condenser, the flow paths should be divided, the inlets of different paths should be as close as possible, the outlet should also be as close as possible, and the inlet and outlet should be as far apart as possible to avoid loss of part of the heat exchange due to reheating and to avoid uneven flow distribution.
In the actual design, if there are more than two branches, a centralized liquid separator and a liquid collector should be used to make the flow between different flow paths as uniform as possible. The pipe paths of the different flow paths are preferably the same, and should flow evenly across the windward side and the leeward side to make the heat exchange uniform.
The above is a brief introduction to the difference between an evaporator and a condenser. The difference between an evaporator and a condenser is that one is a heat-releasing device and the other is a heat-absorbing device.
