TP22-22: Importance of Laboratory Accreditation for Legionella Validation Testing Fans & Associated Equipment

TP22-22: Importance of Laboratory Accreditation for Legionella Validation Testing Fans & Associated EquipmentASHRAE introduced ASHRAE ANSI Standard 188 2015 at the end of June 2015, just before a significant Legionella outbreak in New York City. Since then, CTI has published Guideline 159 and ASHRAE has revised Guideline 12 2000. In the 2018 revision of Standard 188, there was a language change in Appendix C, requiring labs performing routine microbiological testing of water samples to be accredited to a national or international standard. Such testing is an

and other deterioration mechanisms can introduce operational risks and significantly reduce the integrity of the structure

All he got was a horselaugh from everyone

this document discusses how the M-Cycle Enhanced Open and Closed Circuit Cooling Tower designs have the potential in retrofit applications to (1) cool water down to the ambient air dew point temperature and (2) reduce system pressure drop and fan power consumption

By performing thorough annual inspections as described
