  • Let me make myself clear; we build buildings for people, for us. If we don’t take care of the IAQ whay are we building at all?
  • This Low Energy Air Filter is the most efficient LCC solution for both particulate efficiency and energy efficiency. It has the longest life compared to any other F7 filter class on offer for HVAC applications.
  • Here is a simplistic view of a ventilation system, so we can better understand the rest of the presentation. <br /> <br /> We need to take external air and make it suitable for internal use (stable temp, humidity, remove pollutants etc) <br /> <br /> All the components of the ventilation system work to prevent air movement (flow resistance) which we measure as pressure loss. <br /> <br /> Water will not flow up hill against gravity, you need a pump and the input of energy. <br /> <br /> The fan is the same, it requires the input of energy to drive the air through the ventilation system. This is where the energy cost arises from <br /> <br /> The flow resistance of most components is fairly stable through life, <br /> <br /> However the flow resistance of filters depends on their construction and varies through life, this is where the opportunity for energy and cost optimisation arises. <br /> <br />
  • Peter’s history and stance.
  • The opportunity shown on the previous slide needs to be reported and a solution provided. There are a variety of Low Energy Air Filter solutions available that can be tailored for the needs of each individual AHU system.
  • We thank you for attending this webinar and would welcome any comments and questions you would like to send us regarding our <br /> Low Energy Air Filters. <br /> <br /> We would like to make our webinars as relevant and useful as possible to your Air Conditioning Inspections and the reports. <br /> <br /> Our Company Website www.camfil.co.uk has a lot of useful product and applications data. We also have white papers and further information on our specialist websites www.lowenergyairfilter.co.uk <br /> And especially fir Air Conditioning inspectors www.acinspection.co.uk <br /> Our technical staff will be happy to help with any issues . <br /> <br /> We offer on site CPD training for groups of engineers and company staff. Please contact Anne Dempsey for details of the seminars offered. <br /> <br /> Take the opportunity offered by Low Energy Air Filters <br />

  • Clean air solutionsClean air solutionsClean air solutionsClean air solutionsClean air solutions Building Energy Efficiency with Indoor Air Quality Typically 50% of Energy use in Large Buildings is in the HVAC systems Urban air quality is typically above WHO annual warning levels for PM2.5 and NO2.
  • Clean air solutionsClean air solutionsClean air solutionsClean air solutionsClean air solutions Air as a vector of cross contamination concerns base factors Care needs to be taken at a base level to avoid risk and ensure an effective solution
  • Clean air solutionsClean air solutionsClean air solutionsClean air solutionsClean air solutions 1. Clean air that can be inhaled without risk to health. LOW - PM2.5 LOW - NOx LOW - O3 LOW – SOx Use Air filters recommended by EN13779:2007 and tested to EN779:2012 class F7 to F9 2. Temperature 20-22 deg.C. Comfortable for purpose 3. Relative Humidity should be within 45% to 55% 4. Ventilation rate sufficient to dilute CO2 and maintain O2 5. Check building envelope has low leakage 6. Check HVAC plant is fit for purpose, well maintained. Suitable controls and control strategy. Indoor Air Quality from the HVAC AHU system Note: for environmental control lighting and noise levels are also important
  • Clean air solutionsClean air solutionsClean air solutionsClean air solutionsClean air solutions Effective Air Filtration can reduce risk of cross contamination Issues that need to be addressed for optimised air filter selection and use. 1. Are the AHU air filter mountings fit for purpose to minimise air bypass and adequately engineered ? Ref: BS EN 1886:2007 2. Is the filter position in the system correct to deliver clean air and protect system efficiency. Have a system survey if you are not sure. Ref: OAS 3. Choose correct Filter media and type to deliver consistent life performance at required particulate efficiency with minimum use of energy, servicing and other related costs. Ref: BS EN1822:2009 BS EN779:2012 BS EN13779:2007 LCC 4. Select Air Filter configuration for (Bag, Compact) for safe stable performance with minimum stages and include gas phase filtration with particulate filtration when required.
