A

Weibull scale parameter

A-CAES

adiabatic compressed air energy storage

a-si

Amorphous silicon, a thin film PV module semi-conductor material

absorbedor

la parte del colector solar térmico que absorbe radiación solar

absorber

The part of the solar thermal collector which absorbs solar radiation

absorption air vent

A device which releases air, but not fluid, out of a system by absorption

abstraction licence

A licence granted by the local environmental authority which permits a certain amount of water to be taken from a stream

AC

alternating current

ACCF

Africa Climate Change Fund

accionamiento primario

Una máquina que transforma energía del tipo mecánica a energía térmica, eléctrica o de presión o viceversa, por lo general un motor o turbina.

accumulator

An apparatus by means of which energy can be stored, such as a rechargeable battery.

aceite térmico

El aceite térmico es el fluido de transferencia de calor que se usa más comunmente en los arreglos de colectores de concentradores solares. Su composición es de 26.5% bifenilo y 73.5% óxidode difenilo. Este opera en el rango de temperaturas entre los 12-392°C. No es corrosivo pero si es tóxico.

acetogenesis

(bio.) The third step of anaerobic digestion. Products from fermentation (organic acids, alcohols) are converted into hydrogen (H2), carbon dioxide (CO2) and acetic acid (CH3COOH).

ACH

air changes per hour

acid

Traditionally considered any chemical compound that, when dissolved in water, gives a solution with a pH less than 7.0.
Á

ácido

Tradicionalmente, cualquier compuesto químico que, al ser disuelto en agua, genera una solución con pH inferior a 7,0.

acidogenesis

(bio.) During acidogenesis the hydrolysis products which are relatively small, soluble compounds are diffused inside the bacterial cells through the cell membrane and then are either fermented or anaerobically oxidized. These processes occur by a complex consortium of hydrolytic and non-hydrolytic microorganisms which are the source of energy for the acidifying population.
Á

ácidos grasos volátiles (AGV)

Se trata de ácidos producidos por microbios en el ensilaje de azúcar y otras fuentes de carbohidratos. Por definición, son volátiles, lo que significa que se volatilizarán en el aire, en función de la temperatura. Son el primer producto de la degradación de digestión anaeróbica antes de la generación de metano.
A

acristalamiento

Parte de una pared o ventana que consiste en vidrio.

active power

The power (in watts) used by a device to produce useful work. Term used when necessary to distinguish between apparent power, complex power and its components, and active and reactive power. Also called input power.
