2009 Ashrae Hof Chapter 4 — Equation 48 -pg 4.21--

[ \alpha E_t + \epsilon R_t + h_o (T_a - T_so) + \sum_j=1^N \fracY_jA (T_so, t-j - T_si, t-j) = 0 ]

The governing equation on that page is:

in Chapter 4 of the 2009 ASHRAE Handbook—Fundamentals (page 4.21) provides a method for calculating the temperature change of air flowing through an insulated duct or fluid through an insulated pipe . This calculation is essential for engineers to estimate thermal losses or gains within distribution systems, ensuring that air or fluid arrives at its destination at the intended design temperature. Overview of Equation 48 2009 ashrae hof chapter 4 equation 48 -pg 4.21--

Where:

The Heat Balance Method is the most rigorous procedure for calculating cooling and heating loads. It solves four simultaneous balances: [ \alpha E_t + \epsilon R_t + h_o

To serve the engineer searching for the function of Equation 48, we must go back to the . That chapter contained the Response Factor Method equations. It solves four simultaneous balances: To serve the
