Minneapolis Blower Door Model 3 w/ DG-1000 Gauge BD3-KIT-001 is the system of choice for utility DSM programs, energy raters, HVAC contractors and professionals. A. It's not a pass-fail test. When a blower-door test is conducted, the technician depressurizes your house to 50 pascals with respect to the outdoor pressure. The technician then reports the result as a number -- often using the units "air changes per hour @ 50 pascals" or ach50. If the blower door measures a CFM50 leakage of 1,333 then the equation would be 1,333 cubic feet per minute times 60 minutes divided by the volume of 16,000 cubic feet to equal 5 air changes per hour. The home therefore has an infiltration rate of 5 ACH50 (5 air changes per hour at 50 Pa test pressure). ZPD are widely used by weatherization professionals to prioritize air-sealing efforts in houses by estimating the amount of air leakage from attached zones (e.g., attics, crawlspaces, garages, and basements). ZPD techniques typically combine blower door airtightness test results with zone pressure measurements made both before and after an For a limited time get the Rigol 3.2 GHz Real Time Spectrum Analyzer with Vector Network Analysis for 25% off.
