The word condenser refers to two different devices used in industry: one that transforms water vapor into liquid water, and another that stores electrical charges. For practical terms, we are going to define them as thermal capacitor and electrical capacitor . They are used in different areas, so they will be explained separately.

What is a thermal condenser for?

thermal condenser is a piece of equipment, generally made of stainless steel, that is used to transform water vapor into liquid water by cooling. It consists of a cylindrical tank that has a thin spiral tube inside, with inlet and outlet and through which a refrigerant will circulate.

It is used as an indispensable aid in evaporators , in which the main task is to separate water from a mixture. In an evaporator, the initial liquid mixture (which can be juice, sugar water, etc.) is heated until it boils. The first thing to separate is water vapor, which rises up inside the evaporator, to go to a pipe.

This pipe is connected to the condenser, which receives the steam in its tank. Since the evaporator was started, running water at room temperature has been circulated through the internal coil of the condenser. In this way, the separated vapor that is arriving faces the fresh metal of the spiral, and it is condensing , that is, transforming to the liquid state.

The condenser participates in all industrial equipment that involves water evaporation. It is in charge of exchanging heat between running water and the steam that comes from the process. It is therefore classified as a heat exchanger . Another example of a heat exchanger is a car radiator, which helps to cool the air with which the engine is ventilated.

What is an electric capacitor for?

An electrical capacitor is a component that serves to store electrical charges and supply them at a suitable time for a very short period of time. To better understand its operation, we can compare it to a reserve water tank interspersed with others in a network, which guarantee a constant supply in case of outages.

It is made up of two metal plates or armor facing each other and separated by a polarizable insulator, such as paper, air, ceramic, mica, plastic, etc. When direct current is applied, it behaves like an open circuit, and when the applied current is alternating, it acts as a closed circuit, which allows the current to pass in only one direction.

This property of the capacitor is used for filtering alternating current . The fact that the polarizable or dielectric material is insulating means that it does not allow the charges that reach the capacitor to pass through it. However, the fact of being polarizable indicates that its molecules, being in an electric field, are oriented in dipoles.

The negative pole is attracted to the positively charged plate and vice versa. These plates are filled with positive and negative charges respectively, until reaching the same potential of the source. If the source voltage drops, the capacitor yields its charges until the voltage is equal, in this way the external and internal electric fields are equalized.
