Note:

1.Capacities expressed as MBh per initial temperature difference (ITD) between the entering air temperature to the hot water coil and the entering water temperature. Ethylene glycol or other capacities can be determined from the Trane heating coil computer program. Capacity and pressure drop of ethylene glycol varies greatly with temperature and concentration.
