ASHRAE 15 & 34 ADD A
Safety Standard for Refrigeration Systems
Year: 2014
Abstract: FOREWORD
This addendum modifies and clarifies the requirements for discharge of pressure-relief devices, including where refrigerant may be safely discharged in the event of a release. Systems located outdoors are now specifically addressed and include an exemption from the 15 ft (4.57 m) height requirement if meeting specified criteria. The committee reviewed results of analytical dispersion modeling to confirm that location requirements for release of refrigerant on the exterior of a building are adequate to reduce risk of unacceptable concentrations of refrigerant. Requirements for sulfur dioxide were removed because this refrigerant is generally no longer in use. The existing content of Section 9.7.8 and Appendix D were reorganized to provide better clarity.
Note: In this addendum, changes to the current standard are indicated in the text by underlining (for additions) and (for deletions) unless the instructions specifically mention some other means of indicating the changes.
