Daikin AC Releases Guidelines for ASHRAE Standards 15 and 34 Considerations for VRV/VRF Systems

Originally published 06.11.13 by HVACR Business Staff


CARROLLTON, TX – Daikin has recently released a technical article discussing how VRV systems, using distributed refrigerant technology, can be designed adhering to ASHRAE Standards 15 and 34. These standards specify compliant design, construction, installation and operation of refrigeration systems. Originally developed as a safety standard and recognized in October 1930, the scope of the Standard 15 has been expanded over the years but the features and technology of a VRV system have not been specifically addressed.

ASHRAE Standard 15 is an application-based standard, not an equipment design guide, so substantial engineering judgment can be required to follow the standard when designing a system. To that end, a step-by-step process is introduced, covering preliminary system layout, calculations, determining compliance, and remedial design actions, if required. Details under each step in the process provide specific suggestions and examples that can be used to help ensure the design of a system using VRV technology follows the standard. A reference checklist is also included to help facilitate the process.

“The question of compliance of VRV system designs with Standard 15 is one we get on a regular basis. We felt this article would assist engineers and contractors alike in considerations regarding their system designs, and in their conversations with local code enforcement,” said Lennart Stahl, Product Marketing Engineer.
