Question: A heating coil is a heat exchanger that can be used to transfer energy from hot 50% ethylene glycol solution to air for the purposes of space heating. A proposal has been submitted that will focus on the development of a heating coil that contains one row with six loops of coils. Each loop will be 24 in. long and they will be connected to each other by way of 180? smooth return bends. The 50% ethylene glycol solution will be supplied at 200?F and 5 gpm to the heating coil component. A dedicated pump will be required for this component. Design the piping system in the heating coil and specify any major accessories that will be required.
