Energy performance of buildings - Method for calculation of system energy requirements and system efficiencies - DHW instantaneous heat recovery- Module M8
Abstract
This calculation procedure deals with instantaneous DHW heat recovery using a counter-flow heat exchanger between the drain water and the incoming cold water. The proposed procedure calculates the recovered heat, to be taken into account in the overall building energy performance calculation scheme. This calculation procedure doesn't cover storage heat recovery or the use of drain water as a source for a heat pump.
