Why do we need condenser?
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser. The major types of condensers used are (1) water-cooled, (2) air-cooled, and (3) evaporative.
Why do we need condenser in thermal power plant?
In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.
What does a condenser do thermodynamics?
A condenser is designed to transfer heat from a working fluid (e.g. water in a steam power plant) to a secondary fluid or the surrounding air. As the vapor cools, it reaches the saturation temperature, condenses into liquid and releases large quantities of latent heat.
Why is there a condenser in the Rankine Cycle?
The Rankine cycle system consists of a pump, boiler, turbine, and condenser. The boiler heated by the solar heat converts water to superheated steam. This steam is used to run the turbine which powers the generator. Steam leaves the turbine and becomes cooled to liquid state in the condenser.
Why it is called surface condenser?
It is called the surface condenser because the exhausted steam and cooling water does not mix up.
Which condenser is suitable for high capacity power plant?
The function of Surface Condenser in Thermal Power Plant Steam ejectors (or rotary motor-driven exhausts) continuously remove air and gases from the steam and while doing so maintain vacuum. Lowest possible condenser temperatures achieve the lowest possible pressure in the condensing steam assures optimal efficiency.
How does a condenser work in an air conditioner?
The compressor pressurizes the refrigerant gas and sends the refrigerant into the outdoor unit’s condenser coil. A large fan pulls outdoor air through the condenser coil, allowing the air to absorb heating energy from the home and release it outside. During this process, the refrigerant is converted back to a liquid.
Why is Rankine cycle considered most practical cycle?
The efficiency of the Rankine cycle is limited by the high heat of vaporization by the fluid. The fluid must be cycled through and reused constantly, therefore, water is the most practical fluid for this cycle. This means the pump requires less work to compress the water—resulting in higher overall efficiencies.
