Se conoce por evaporador al intercambiador
de calor donde se
produce la transferencia de energía térmica desde un medio a ser enfriado hacia el
fluido refrigerante que
circula en el interior del dispositivo. Su nombre proviene del cambio de estado sufrido
por el refrigerante al recibir esta energía, luego de una brusca expansión que
reduce su temperatura. Durante el proceso de evaporación, el fluido pasa del estado líquido al gaseoso.
Los evaporadores se encuentran en todos los
sistemas de refrigeración como neveras, equipos de aire acondicionado y cámaras
frigoríficas. Su diseño, tamaño y capacidad depende de la aplicación
y carga térmica de cada uso.
Compuertas para
control de flujo de aire; controladas a través de paneles de control de zona
para aplicaciones de aire acondicionado y calefacción. Pueden ser usados para
controlar el flujo de inyección en cada zona o bien para el desfogue del flujo
de aire excedente hacia la ductería del retorno.
La
condensación se puede producir bien utilizando aire mediante el uso de un
ventilador o con agua (esta última suele ser en circuito cerrado con torre de
refrigeración, en un río o la mar). La condensación sirve para condensar el
vapor, después de realizar un trabajo termodinámico p.ej. una turbina de vapor
o para condensar el vapor comprimido de un compresor de frío en un circuito
frigorífico. Cabe la posibilidad de seguir enfriando ese fluido, obteniéndose
líquido sube enfriado en el caso del aire
acondicionado.
El condensador termodinámico es
utilizado muchas veces en la industria de la refrigeración, el aire
acondicionado o en la
industria naval y en la producción de energía eléctrica, en centrales térmicas o nucleares.
Adopta
diferentes formas según el fluido y el medio. En el caso de un sistema
fluido/aire, está compuesto por uno tubo de diámetro constante que curva 180°
cada cierta longitud y unas láminas, generalmente de aluminio, entre las que
circula el aire.
Un
condensador es un cambiador de calor latente que convierte el vapor de su estado
gaseoso a su estado líquido, también conocido como fase de transición. El
propósito es condensar la salida (o extractor) de vapor de la turbina de vapor para así obtener máxima eficiencia e
igualmente obtener el vapor condensado en forma de agua pura de regreso a la caldera.
Condensando el vapor del extractor de la turbina de vapor, la presión del extractor
es reducida arriba de la presión
atmosférica hasta
debajo de la presión
atmosférica, incrementando la caída de presión del vapor entre la
entrada y la salida de la turbina de vapor.
Esta reducción de la presión en el extractor de la turbina de vapor, genera más calor por
unidad de masa de vapor entregado a la turbina de vapor, por conversión de poder
mecánico.
Is known evaporator heat exchanger which produces the transfer of thermal energy from one medium to be cooled to the cooling fluid circulating inside the device. Its name comes from the change of state undergone by the refrigerant to receive this energy, following a sharp expansion that reduces its temperature. During the evaporation process, the fluid passes from liquid to gas.
The evaporators are found in all cooling systems such as refrigerators, air conditioners and refrigerators. Its design, size and capacity depends on the thermal load application and each use.
Gates to control air flow, controlled by zone control panels for air conditioning and heating. Can be used to control the flow of injection in each zone or for the exhaust air flow over into the return ductwork.
The condensation can be produced by using air using a fan or with water (the latter being generally in closed circuit with cooling tower in a river or the sea). The condensation is used to condense the steam, after performing a thermodynamic work eg a steam turbine or steam to condense the compressed cold compressed in a refrigeration circuit. It is possible that further cooling fluid, resulting cooled liquid rises in the case of air conditioning.The thermodynamic capacitor is used many times in the industry of refrigeration, air conditioning or in the shipping industry and the production of electricity in power plants or nuclear weapons.Takes different forms depending on the fluid and the environment. In the case of a fluid / air comprises a tube of constant diameter which each 180 ° bend and a certain length sheets, usually of aluminum, between the circulating air.A capacitor is a latent heat exchanger converts its gaseous vapor to liquid, also known as phase transition. The purpose is to condense the outlet (or exhaust) of steam from the steam turbine so as to obtain maximum efficiency and also obtain the condensate in the form of pure water back to the boiler.Condensing the steam turbine exhaust steam, the pressure of the extractor is reduced above the atmospheric pressure to below atmospheric pressure, increasing the steam pressure drop between inlet and outlet of the steam turbine. This reduction in pressure in the exhaust steam of the turbine, generates more heat per unit mass of steam delivered to the steam turbine, by converting mechanical power.
