Carbon Cycle Chemical Reactions Involved: Photosynthesis: Air and water molecules and the energy from the sun to produce a simple sugar such as glucose and oxygen molecules as a by product. During photosynthesis plants use carbon dioxide and produce oxygen.
Similar to shore power for ships, a ground power unit (GPU) may be used to supply electric power for an aircraft on the ground, to sustain interior lighting, ventilation and other requirements before starting of the main engines or the aircraft auxiliary power unit (APU).
â¢ Coils are the main devices for transferring energy to/from the airstream in an air-handling system. â¢ Heat Transfer Media â Hydronic Fluid (Water) â Steam â Direct Expansion â¢ Important Coil Load Concepts â Apparatus Dew Point â Bypass Factor.1. Air Conditioning Design-Psychrometrics & Coil Load Calculation.. Bypass Factor. Some of the air flowing through the coil impinges on the water tubes or the fins and is cooled to the ADP. Other air passes through unchanged. Coil Entering Air. Fin. The percentage of air that passes through the coil unchanged is called the bypass factor.
