DIN V 18599-5-2007 建筑物能效.计算加热、冷却、通风、家用热水和照明用净能、最终和初始能量.第5部分:加热系统最终能量要求
Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Part 5: Final energy demand of heating systems
The DIN V 18599 series of prestandards provides a methodology for calculating the overall energy balance of
buildings. The described algorithm is applicable to the calculation of energy balances for:
-- residential buildings and non-residential buildings;
-- planned or new building construction and existing buildings.
The procedure for calculating the balances is suitable for:
-- balancing the energy use of buildings with partially pre-determined boundary conditions;
balancing the energy use of buildings with freely-selectable boundary conditions from the general
engineering aspect, e.g. with the objective of achieving a good comparison between calculated and
measured energy ratings.
The balance calculations take into account the energy use for:
-- heating,
-- ventilation,
-- air conditioning (including cooling and humidification),
-- heating the domestic hot water supply, and
-- lighting
of buildings, including the additional electric power input (auxiliary energy) which is directly related to the
energy supply.
This document determines the energy use of the heating system for the building according to its different
subsystems. It is also possible to use the results from some subsystems for calculating the delivery of heat to
the sectors covered by DIN V 18599-6 to DIN V 18599-8 and vice-versa.
It is also possible to calculate the energy balances of several building zones in which there are several units to
be balanced.
This document describes the energy use of heating systems with their subsystems (control and emission,
distribution, storage and generation). For this purpose, both the thermal losses and the auxiliary energy of the
individual subsystems are determined and, provided these occur within the heated zone, are made available
for the ensuing calculations described in DIN V 18599-1 and DIN V 18599-2. Information is given on the
possible influence of domestic hot water generation according to DIN V 18599-8. Recourse to the heating
system by other systems (e.g. ventilation of residential buildings as in DIN V 18599-6, or ventilation and air
conditioning systems in non-residential buildings as in DIN V 18599-7), that can make demands on certain
subsystems, can accordingly be taken into account and analysed, with DIN V 18599-1 acting as the link
between the Pads.
It is assumed that heating systems are operated as intended and in keeping with accepted best practices.
Special guidance (e.g. with regard to the hydraulic balance of the hot water heating system) is given in
VDMA 24199.
