RIGHT-J CALCULATION PROCEDURES A, B, C, D <br /> Entire House <br /> Goodin Company Job: H060919 DIESEN <br /> 09-19-06 <br /> 285 Como Ave.,St.Paul,MN 55103-1862 Phone:651-489-8831 Fax:651-489-8837 Email:john.alberg@goodinco.com Web:www.goodinco.com <br /> Procedure A-Winter Infiltration HTM Calculation* <br /> 1. Winter infiltration AVF <br /> 0.70 ach x 19656 W x 0.0167 = 230 cfm <br /> 2. Winter infiltration load <br /> 1.1 x230 cfm x 81 °F Winter TD = 20473 Btuh <br /> 3. Winter infiltration HTM <br /> 20473 Btuh / 344 ft2 Total window = 59.5 Btuh/ft2 <br /> and door area <br /> Procedure B- Summer Infiltration HTM Calculation <br /> 1. Summer infiltration AVF <br /> 0.40 ach x 19656 W x 0.0167 = 131 cfm <br /> 2. Summer infiltration load <br /> 1.1 x 131 cfm x 13 °F Summer TD = 1878 Btuh <br /> 3. Summer infiltration HTM <br /> 1878 Btuh / 344 ft2 Total window = 5.5 Btuh/ft2 <br /> and door area <br /> Procedure C - Latent Infiltration Gain <br /> 0.68 x22 gr/Ib moist.diff. x 131 cfm = 1975 Btuh <br /> Procedure D - Equipment Sizing Loads <br /> 1. Sensible sizing load <br /> Sensible ventilation load <br /> 1.1 x 0 cfm vent. x 13 °F Summer TD = 0 Btuh <br /> Sensible load for structure(Line 19) + 24655 Btuh <br /> Sum of ventilation and structure loads = 24655 Btuh <br /> Rating and temperature swing multiplier x 0.93 <br /> Equipment sizing load-sensible = 22929 Btuh <br /> 2. Latent sizing load <br /> Latent ventilation load <br /> 0.68 x 0 cfm vent. x 22 gr/Ib moist.diff. = 0 Btuh <br /> Internal loads = 230 Btuh x 6 people + 1380 Btuh <br /> Infiltration load from Procedure C + 1975 Btuh <br /> Equipment sizing load-latent = 3355 Btuh <br /> *Construction Quality is: a No. of Fireplaces is: 0 <br /> Printout certified by ACCA to meet all requirements of Manual J 7th Ed. <br /> wrig htsoft Right-Suite ResidentialTM 5.0.64 RSR30011 2006 Sep 19 11:44:08 <br /> XOC C:\My Documents\Wrightsoft HVAC\H060919 DIESEN.rsr Page 1 <br />
