    code req'd freeze protection

    Reply Quote
    Does anyone know if any code, either mechanical, plumbing, etc., requires some type of freeze protection on chilled water HVAC systems? I'm investigating a large qty of public buildings where no freeze proctection was in place and the weather got a bit cold one night. A loss of over 20 coils occured. Just trying to locate codes if available.
