For water, after doing the required conversions and inputting the correct specific heat, the sensible heat equation becomes: Qwater = 500 * GPM * (Leaving Water Temperature - Entering Water Temperature). Emergent Coils provides information on how to measure or size your hot water coil. First a design reheat time needs to be established, this normal assumes that all the hot water has been used and the tank is filled with cold mains water. 0000026906 00000 n xref Open expansion tanks must also be located above the highest heating element, in general on the top of buildings, where they may be exposed to freezing. The iterative solution uses an interval-halving routine and needs a termination criteria that is set here. In the simulation, the necessary hot water flow rate is determined by the coil model to meet the relevant control requirements. 0000012375 00000 n The water coil model does result in a design capacity very near your calculations.
