Unidad fan-coil
una unidad de descarga alternativa para su aplicación al sistema de inducción que se muestra en la página anterior. En lugar de la inyección de aire por boquilla, se utiliza un ventilador de baja potencia para dispersar una mezcla de aire primario y secundario después del recalentamiento o enfriamiento desde un intercambiador de energía dentro de la unidad.
Difusor de inducción
Otra alternativa que también utiliza una mezcla de aire ambiental recirculado con aire primario. Estos se ubican al final de los conductos derivados y combinan un difusor con una cámara de mezcla de aire primaria y secundaria simple. El aire primario de alta velocidad se mezcla con el aire secundario de baja velocidad aspirado hacia un techo pleno desde la habitación de abajo. En esta situación se pueden utilizar rejillas de extracción de iluminación con cierta ventaja.
FREQUENTLY ASKED QUESTIONS
A fan coil unit works in conjunction with an induction diffuser to distribute conditioned air throughout a building. The fan coil unit reheats or cools the air, which is then dispersed by the induction diffuser into the occupied space. The induction diffuser uses the momentum of the primary air to induce a flow of secondary air, creating a high-velocity jet of air that can penetrate deep into the space.
The advantages of using a fan coil unit over a traditional air handling unit include lower capital costs, reduced energy consumption, and increased flexibility in terms of layout and design. Fan coil units are also generally quieter and more compact than traditional air handling units, making them ideal for applications where space is limited.
The design of a fan coil unit has a significant impact on its performance and efficiency. Key design factors include the type and size of the fan, the coil design and configuration, and the layout of the unit. A well-designed fan coil unit can provide high airflow rates at low pressure drops, while also minimizing energy consumption and noise levels.
Fan coil units are commonly used in commercial and residential buildings, including offices, hotels, hospitals, and apartments. They are particularly well-suited for applications where there is a need for individual zone control, such as in hotels and apartments, or where there are specific air quality requirements, such as in hospitals.
Fan coil units compare favorably to other types of air distribution systems, such as VAV (Variable Air Volume) systems, in terms of energy efficiency and cost-effectiveness. While VAV systems can provide more precise control over airflow rates, fan coil units offer a simpler and more cost-effective solution for many applications.
Key considerations for selecting and sizing a fan coil unit include the required airflow rate, the available power supply, and the noise level requirements. It is also important to consider the specific application and the desired level of zone control, as well as any specific air quality or filtration requirements.
