Chiller (500kW)

This data set has been modeled according to the European Standard EN 15804+A2 for Sustainable Building. Results are depicted in modules that allow the structured expression of results over the entire life cycle.

The data set only includes the manufacturing and disposal of the chiller, not its operation and not the required refrigerant. The main raw materials of the unit are steel (approx. 45 m.%) copper (approx. 29 m.%) and cast iron (approx. 22 m.%). For these metals (steel, copper and cast iron), the primary upstream chains were used in the sense of a coservative approach (e.g. the blast furnace route in the case of steel). The life cycle assessment is dominated by the production of the above mentioned metals. In module C1, a dismantling with machinery is assumed, collecting losses are neglected. The transport in module C2 to the recycling plant takes place with a truck (50km). Tratment of metal components: Collecting losses are neglected. It is assumed that all metals reach the end of the waste status immediately after dismantling. This means that the loads for processing and the credits for the substitution of primary material are shown in Module D. Module D includes loads for sorting, remelting, slag treatment, landfill, filtration of dusts and dross treatment. Credits are given for the net scrap amount (amount returned minus secondary material content, minus processing losses) for the average material mix (from different alloys). Treatment of plastic components: Module C3 takes into account the grinding and thermal treatment (combustion) of the material. When calculating combustion emissions and credits, the specific calorific value of each material and the material composition are taken into account. In module D credits for the substitution of electricity (German electricity mix) and thermal energy (from natural gas) are given.

Chillers are used to cool buildings or technical systems.
