Processo di dimensionamento e selezione della valvola di espansione della refrigerazione
La corretta selezione e dimensionamento delle valvole di espansione della refrigerazione è un processo sistematico che richiede un'attenta considerazione di più parametri. La selezione della giusta valvola di espansione comporta la comprensione dei requisiti di sistema, il calcolo delle capacità corrette e la contabilità per condizioni operative come il sottolineatura e la caduta di pressione.
Dimensizzazione e selezione dell'evaporatore di refrigerazione
Il dimensionamento e la selezione dell'evaporatore rappresentano elementi critici nella progettazione del sistema di refrigerazione. Il processo richiede un approccio metodico che considera non solo il carico di raffreddamento, ma anche l'integrazione del sistema, le proprietà del refrigerante, i requisiti dell'applicazione e gli obiettivi di efficienza energetica.
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 geometria dietro i calcoli dell'energia solare
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.
