The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC. It’s critical to bring in fresh, outside air to maintain air indoor quality, and with our DOAS you can count on high efficiency, proven performance for both heating and cooling applications in even the most extreme weather and climate conditions. The service model represents Specifically my dealings have been with Aaon units, but it seems to me that an ERU is an ERU. 2. The ERU has a range of technology using satellite phone systems, high-frequency and very high frequency radio systems and VSAT, depending on the geographical location and needs. air terminal units – single duct variable air volume . 0000001726 00000 n 47 0 obj << /Linearized 1 /O 49 /H [ 1002 391 ] /L 218645 /E 50551 /N 12 /T 217587 >> endobj xref 47 30 0000000016 00000 n When the space pressure is greater than the return air pressure drop and outdoor atmospheric pressure, the gravity relief air damper opens and provides the required exhaust operation.
