Ductwork 選型 — 速度 與 摩擦 方法

Overview

Engineering reference data for Ductwork Sizing — Velocity and Friction Method in HVAC systems.

Key Formulas

Sensible Heat

$Q = \dot{m} c_p \Delta T$

Heat causing temperature change.

Latent Heat

$Q = \dot{m} h_{fg} \Delta\omega$

Heat causing moisture change.

COP (Cooling)

$COP = Q_c / W$

Coefficient of performance.
