What is the principle of condenser?
Principle of operation 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. The condenser relies on the efficient heat transfer that occurs during phase changes, in this case during the condensation of a vapor into a liquid.
How does a condenser work?
Condenser: The condenser is a set of coils, also located inside the outdoor unit. Here, a fan blows across the coils, dissipating the heat from the refrigerant inside them and allowing it to convert back into a liquid, at which point it’s sent back inside to start the process over again.
What is condenser PDF?
The Condenser removes the heat from refrigerant carried from evaporator and added by compressor and converts the vapour refrigerant into liquid refrigerant. ∎ It is an Heat Exchanger in which heat transfer takes place from high temperature vapour to a low temperature liquid with help of cooling like air or water.
How does a condenser and evaporator work?
While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. An expansion valve before the evaporator restricts the flow of refrigerant, forcing it through a narrow orifice and converting it back to a vaporized state, ready to absorb more heat energy from your home.
How does compressor and condenser work?
Refrigerant flows through the compressor, which raises the pressure of the refrigerant. Next the refrigerant flows through the condenser, where it condenses from vapor form to liquid form, giving off heat in the process. The refrigerant draws heat from the evaporator which causes the regrigerant to vaporize.
Where is AC condenser?
Your air conditioner’s condenser is contained in the large, square unit outside your house. Although the whole unit is called the “condenser unit,” it actually contains multiple components, including the condenser tubes and fins, the compressor, a fan and copper tubing, as well as valves and switches.
How do you calculate cooling load of condenser?
Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per Kelvin. This gives us a final answer of Q = 2,500kW of cooling.
What is condenser and evaporator?
The evaporator coil contains cold refrigerant that absorbs heat from your air. The condenser coil is where the refrigerant goes to get rid of this heat so it can can come back to absorb more. Your Evaporator Coil: The Cold Side. The evaporator coil is located indoors, inside or near your air handler.
Why is condenser used?
condenser, device for reducing a gas or vapour to a liquid. Condensers are employed in power plants to condense exhaust steam from turbines and in refrigeration plants to condense refrigerant vapours, such as ammonia and fluorinated hydrocarbons.
What are the three phases of the condenser?
What are the three phases of the condenser? De-superheat, condense, and subcool.
How does a water cooled condenser avoid heat?
If the compressor-motor is refrigerant cooled, the chiller also rejects heat generated by motor inefficiency. Air- cooled condensers use fans to facilitate cooling by the ambient air. Water- cooled condensers typically use an evaporative cooling tower.
How does a condenser and an evaporator work?
Condensers and evaporators are basically heat exchangers in which the refrigerant undergoes a phase change. In condensers the refrigerant vapor condenses by rejecting heat to an fluid, which acts as a heat sink. evaporators, the liquid refrigerant evaporates by extracting heat from an external fluid (low temperature heat
How does a refrigerant pump work in a chiller?
Refrigerant loop. Using a phase-change refrigerant, the chiller’s compressor pumps heatfrom the chilled water to the condenser water. Condenser water loop. Water absorbs heat from the chiller’s condenser, and the con-denser water pump sends it to the cooling tower.
What are the components of a vapor compression chiller?
Some reciprocating chillers are also available. Chillers can be either air- or water-cooled. Major vapor- compression chiller components include an evaporator, compressor(s), condenser, and expansion device(s) (Figure 1).
