摘要：This paper discusses issues related to cooling load and energy
consumption for air conditioning systems and presents the results of
calculations conducted for six different climate localizations: three in
Poland (Bialystok, Warsaw, Wroclaw) and three in Spain (Burgos, Madrid,
Cordoba). Analysis was conducted for a same lecture hall design for 100
users locates in the different cities. During cooling load calculations, we
focused on gains from diverse type of heat sources: electrical devices, air
infiltration, heat transfer trough envelope and occupants. Calculations were
made for a comfort temperature that was set at 22°C in Poland and 24°C in
Spain following previous studies [11]. The highest contributions to cooling
load correspond to occupancy and solar gains which depends mainly on
outdoor conditions. In Poland, cooling load was found similar for different
locations, while in Spain, they are big differences between cities located in
North and South of this country by effect of different outdoor conditions.
The work also compares cost of air condition annual energy consumption
costs for the air conditioning system. Highest cost for cooling was found in
Spain (Cordoba) with value (2629 €) almost 378% higher than average
Polish cost.
