  22. 22. California Center for Sustainable Energy HVAC Efficiency and California T-24 Slide 39 Prescriptive Requirements New or replacement space-conditioning systems §152(b)1C A new or replacement space conditioning system installed in an existing dwelling includes a completely new or replacement duct system and a completely new or replacement air handler. A new or replacement space conditioning system installed in an existing dwelling includes a completely new or replacement duct system* and a completely new or replacement air handler. HVAC Efficiency and California T-24 Slide 40 Introduction--2008 Changeout Rules Page 20
  23. 23. California Center for Sustainable Energy Definition: completely new or replacement duct system A completely new or replacement duct system can also include existing parts of the original duct system (e.g., register boots, air handler, coil, plenums, etc.) if those parts are accessible and they can be sealed. HVAC Efficiency and California T-24 Slide 41 Target Leakage "completely new or replacement duct system" If the system is substantially new, and includes the furnace cabinet (air handler) and other existing parts of the original system that are all accessible, an attempt should be made to seal the duct system to meet the 6% (of system fan airflow) leakage criteria. HVAC Efficiency and California T-24 Slide 42 Introduction--2008 Changeout Rules Page 21
  24. 24. California Center for Sustainable Energy Target Leakage—(CONTINUED) "new or replacement completely duct system" If the 6% leakage rate criteria cannot be met, a smoke test should be performed to verify that the excess leakage is coming only from the furnace cabinet, and not from other accessible portions of the duct system. Note that the protocol for Smoke Test of Accessible-duct Sealing given in Reference Residential Appendix RA3.1.4.3.7 and makes an exception for the furnace cabinet. HVAC Efficiency and California T-24 Slide 43 Definition: Accessibility Accessible is defined as having access thereto, but which first may require removal or opening of access panels, doors, or similar obstructions. For example, if walls and drywalls have to be moved or removed, or if the ducts are buried under insulation, or if a joint in the duct system is in too small a space between framing member for someone to be able to get to the joint to seal it, then that portion of the duct system is not accessible and is not required to be sealed even if smoke testing determines that the duct leaks in that inaccessible location. HVAC Efficiency and California T-24 Slide 44 Introduction--2008 Changeout Rules Page 22
  25. 25. California Center for Sustainable Energy Airflow and Fan Watt Draw In climate zones 10-15 when a new or replacement space conditioning space-conditioning system is installed, the central forced air fan must simultaneously in every zonal control mode demonstrate an airflow of greater than 350 CFM/ton of nominal cooling, and a fan watt draw of 0.58 W/CFM in accordance with the procedures in Reference Residential Appendix RA3.3. In addition, the system installer must provide in the supply plenum, a hole for the placement of a static pressure probe. HVAC Efficiency and California T-24 Slide 45 Airflow and Fan Watt Draw (CONTINUED) In addition, the system installer must provide in the supply plenum, a hole for the placement of a static pressure probe (HSPP) or a permanently installed static pressure probe (PSPP), downstream of the evaporative coil, which meets the specifications of Reference Residential Appendix Section RA3.3.1.

California Center for Sustainable Energy If a pressure of 25 Pa cannot be achieved, remove the Mid range low flow plate with the 2 inch diameter hole in it and adjust the speed till 25 Pa is achieved. If “Flow” displays “TOO LOW!”, add the Low range 1 iinch di h diameter nozzle. t l To speed up the test and improve accuracy ensure that “cfm @ 25.0 Pa” is displayed to the right of the flow. This will give you results at 25 regardless of your test pressure, meaning that you don’t have to get the test pressure exact; within 1 Pa is perfect. The DM-2 will then display the result you would get if you achieved exactly 25 Pa. To T get thi f t t this feature, press th [@] k the key. If 25 iis nott displayed, change this in [Setup] by locating the “@ Pressure” line, press [Enter], [2], [5] , [Enter], [Setup] to change it. When using the @ feature, “n” should be displayed as “0.60” for duct systems. Change this in Setup if needed. Duct Testing Procedure Page 23
