Rooftop Unit (RTU) Product Data
(Page 14 of 25) - Recommend not using demand controlled ventilation in a medical building where OA quantities are driven off codes that go beyond ASHRAE 62.1.
Note this can easily be disabled in the field but there may be some cost savings in not purchasing the CO2 sensors and not programming the feature.
Please confirm OA intake will be at least 36" above the roof. This was already noted by the EOR but a response was not found.
Please provide fan curves showing performance of a single fan running as well as with both fans running. Typical RTU-1 and RTU-2.
Please confirm each fan will be provided with a back draft damper to allow the unit to continue to run if one fan goes down without short cycling.
Please confirm the modulation capabilities of the compressors. Are the compressors variable speed for load modulation? What is the expected turn down ratio?
