Proceso de selección y tamaño de la válvula de expansión de refrigeración
La selección y el tamaño adecuados de las válvulas de expansión de refrigeración es un proceso sistemático que requiere una cuidadosa consideración de múltiples parámetros. Seleccionar la válvula de expansión correcta implica comprender los requisitos del sistema, calcular las capacidades correctas y tener en cuenta las condiciones de funcionamiento, como el subenfriamiento y la caída de presión.
Refrigeration Evaporator Sizing and Selection
Evaporator sizing and selection represent critical elements in refrigeration system design. The process requires a methodical approach that considers not only the cooling load but also system integration, refrigerant properties, application requirements, and energy efficiency goals.
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.
The Geometry Behind Solar Energy Calculations
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.
