Dimensionnement et sélection de l'évaporateur de réfrigération
Le dimensionnement et la sélection des évaporateurs représentent des éléments critiques dans la conception du système de réfrigération. Le processus nécessite une approche méthodique qui considère non seulement la charge de refroidissement mais également l'intégration du système, les propriétés de réfrigérant, les exigences d'application et les objectifs d'efficacité énergétique.
Lighting Rules Of Thumb (HVAC)
Using lighting rules of thumb for final design of HVAC and lighting.
Infiltration Rules Of Thumb
The infiltration rate is the volumetric flow rate of outside air into a building, typically in cubic feet per minute (CFM) or liters per second (LPS). The air exchange rate, (I), is the number of interior volume air changes that occur per hour, and has units of 1/h.
La géométrie derrière les calculs d'énergie solaire
Solar Geometric Angles are all critical to the calculation of solar energy on any given surface at some orientation. To calculate the energy balance across any time scale with respect to the incident solar radiation, you must know the geometric relationships that define the spherical realities of planetary motion relative to the sun for specific tilted surfaces on the planet.
