Witte on 12 August 2014 09:35 PM\r\n\r\n\r\nPosted on: 18 July 2014 06:54 PM\r\nYour description sounds very familiar to something I heard a while ago. \r\n I am checking to see if there is documentation or something else that needs updating.\r\n 'Richard Raustad\r\n\r\nThanks Richard,\r\n I tested using autosized inputs and I compared results.\r\n To the simulation runs OK I must multiply the cooling coil capacities (both in zone and system), but must not multiply the air flow. \r\n I look at all the syzing summaries available: component, equipment and HVAC. In this case, especially the VRF component summary outputs.\r\n Tks a lot,\r\n Thais Inatomi\r\n\r\nYou might test using autosized inputs to see what happens.\r\n I also suggest sending us the 2 input files with only the 1 change you mentioned.\r\n This way we know what you have entered as inputs.\r\n Also tell us exactly which table reports you are looking at.\r\n 'Richard Raustad\r\n\r\nHi,\r\n\r\n I’m modeling VRF system with actual designed capacities and actual air flows. \r\n The model has one floor multiplied by 8 (I’m using zone list/zone group for that).\r\n I’m having problems with the output table considering this multiplied floor.\r\n\r\n Should I input capacities and flows from VRF units multiplied by 8 in the VRF zones and systems? Or not?\r\n When I do not multiply it, I have a lot of unmet load hours. However, the table presents all the flows and capacities multiplied automaticaly by 8. That would be OK if the unmet load hours weren’t so many.\r\n When I put the multiplied zone list/group to only 1, the unmet load hours completly disappear.\r\n When I input all the capacities and flows multiplied by 8, the table results are clearly wrong (not only the equipments sizes but also the energy consumption from fans and cooling coils).\r\n\r\n I am understanding that maybe there is a bug with the account of unmet load hours output. \r\n Could you help me?\r\n\r\n thanks a lot.\r\n Thais Inatomi\r\n\r\nUser files\r\nAlthough idf files were requested from the user, it appears that they were never sent\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/NREL/EnergyPlus/issues/comments/139824064","html_url":"https://github.com/NREL/EnergyPlus/issues/4402#issuecomment-139824064","issue_url":"https://api.github.com/repos/NREL/EnergyPlus/issues/4402","id":139824064,"user":{"login":"rraustad","id":5778156,"avatar_url":"https://avatars.githubusercontent.com/u/5778156?v=3","gravatar_id":"","url":"https://api.github.com/users/rraustad","html_url":"https://github.com/rraustad","followers_url":"https://api.github.com/users/rraustad/followers","following_url":"https://api.github.com/users/rraustad/following{/other_user}","gists_url":"https://api.github.com/users/rraustad/gists{/gist_id}","starred_url":"https://api.github.com/users/rraustad/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rraustad/subscriptions","organizations_url":"https://api.github.com/users/rraustad/orgs","repos_url":"https://api.github.com/users/rraustad/repos","events_url":"https://api.github.com/users/rraustad/events{/privacy}","received_events_url":"https://api.github.com/users/rraustad/received_events","type":"User","site_admin":false},"created_at":"2015-09-12T22:10:38Z","updated_at":"2015-09-12T22:10:38Z","body":"There appears to be issues with zone list and/or group multipliers.
