Capacity calculation of instantaneous DHW production equipment for direct consumption supply systems, or supply systems using storage tanks.
For both the direct and auxiliary systems, everything will be managed from the general data in the program.
When the outline for the installation of a DHW production group is carried out, users will receive the information necessary for establishing its power.
Users must enter the performance of the DHW production system (a performance that must consider exchange, accumulation, distribution, and recirculation losses).
For installations where 100% of the demand is accumulated, it is only necessary to add the hours in which the heating of this accumulation is stipulated. For installations with less than 100% accumulation demand, a use factor of the accumulation volume must be defined. This factor depends on the geometry (slenderness) and the number of storage tanks, as inside the tanks is a mixed area of hot and cold water, in which the temperature is lower than that in use so that the tank is equivalent to one with a lower capacity.
