DIN V 18599-7-2007 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7部分:非住宅建筑用空气处理和空调系统最终能量要求
Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Part 7: Final energy demand of air-handling and air-conditioning systems for non-residential buil
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 constructions 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.
DIN V 18599-7 applies to heating, ventilation and air conditioning systems of non-residential buildings (see
Figure 2) and uses the energy need for room conditioning calculated as described in DIN V 18599-2 and the
energy need for air handling (heating, cooling and humidification) calculated as described in DIN V 18599-3.
The methods described enable calculation of the heat output for heating functions of the HVAC system. The
values calculated are output values for the calculations described in DIN V 18599-5.
Furthermore, the (net) generator cooling output for room conditioning and air handling cooling functions is
determined and the delivered energy for refrigeration equipment (electrical energy) and the generator heat
output for the thermal chillers are calculated with the aid of a method for cooling generation based on
characteristic values. These are then used as output values for the calculations in DIN V 18599-5.
In the same way, the energy used for steam humidification (i.e. delivered energy in the form of electrical
energy, gas and oil) is calculated.
Additional methods for calculating the energy requirements of the chilled water and cooling-water distribution
pumps as well as of any other pumps and ancillary drives needed are described.
