Within DHW Systems, users can now define DHW accumulators, to be able to account for the effect of their heat losses on energy consumption for this building service.
The DHW accumulators are defined within the corresponding DHW System, using their global loss coefficient (UA). An assistant is provided to calculate the UA value of the accumulator based on its dimensions and its insulation properties. The heat losses produced in the DHW accumulators represent an increase in the demand for energy, which will be provided by the production equipment that is associated with the same DHW system.
An accumulator associated with a specific DHW production equipment set can also be defined. In this case, heat losses due to the accumulation will be compensated only by that production equipment. This option allows users to define equipment such as electric heat accumulators or heat pumps for DHW.
