DIN V 18599-9-2007 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9部分:热电联产最终和最初能量要求
Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Part 9: Final and primary energy demand of combined heat and power generation plants
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 describes a procedure by which to determine the delivered energy expenditure for heat
generation in the process involving the simultaneous, interdependent generation of electrical power and heat
(cogeneration, CHP).
For the calculations, the energy need for heating Qh,outg calculated in DIN V 18599-5 as well as the
performance data of the units and equipment are required. These data can be measured or calculated in a
simple manner as specified in this document or according to the standards referred to in this document. The
result of the calculations specified in this document is the delivered energy used (delivered energy
expenditure) Qh,f, this being required in order to determine the primary energy used (primary energy
expenditure), as specified in DIN V 18599-1.
Figure 2 shows the scope of the present document as a diagram. For the reader's orientation, all other parts
of the DIN 18599 series of prestandards contain an illustration similar to Figure 2 as shown here, and in which
the respective energy components dealt with are shown in colour.
