Data center power densities have surged to 12-30 kW per rack, making liquid cooling essential. Learn how single-phase and two-phase direct-to-chip systems work, refrigerant selection criteria, and critical design considerations for hoses, tubing, and couplings in modern high-density data centers.
Equilibrio del flujo de aire de conductos
El equilibrio de los sistemas aéreos (conductos) se puede lograr de varias maneras. El método más común para lograr el equilibrio de conductos es el método proporcional. Cada difusor se ajusta para suministrar el porcentaje correcto del volumen de aire total en los conductos.
Características de la válvula
¿Por qué debemos ser conscientes de las características de la válvula? Cada componente en un sistema hidrónico tiene cierto nivel de influencia en el control y el rendimiento de un sistema hidrónico. Las válvulas son clave porque son los dispositivos de control en las áreas críticas de transferencia de calor.

Esta guía se centra en sistemas que usan refrigerante-22 (R-22). Si bien los requisitos generales son los mismos para los sistemas que usan otros refrigerantes, las velocidades y las caídas de presión diferirán.
Sistemas de almacenamiento de hielo
El almacenamiento de energía térmica (TES) implica agregar energía (térmica) a un medio de almacenamiento y luego eliminarla de ese medio para usar en otro momento. Esto puede implicar almacenar energía térmica a altas temperaturas (almacenamiento de calor) o a bajas temperaturas (almacenamiento frío).
Método de análisis de costos del ciclo de vida
El método de análisis de costos del ciclo de vida es el método más comúnmente aceptado para evaluar los beneficios económicos de los proyectos de conservación de energía durante su vida. Por lo general, el método se utiliza para evaluar al menos dos alternativas de un proyecto determinado (por ejemplo, evaluar dos alternativas para la instalación de un nuevo sistema HVAC: un sistema VAV o un sistema de bomba de calor para condicionar el edificio). Solo se seleccionará una alternativa para la implementación basada en el análisis económico.

Air Conditioning Condensate calculator
Air conditioning condensate is the water that is produced as a result of the cooling process in an air conditioning system. When the air conditioning system cools the air in a building, it removes moisture from the air, which condenses on the cool coils of the air conditioning system. This condensation is collected and drained away through a condensate drain pipe. The water that is collected in the condensate drain is typically referred to as air conditioning condensate.
