Absorption cooling technology

Absorption cooling technology

District cooling based on absorption cooling is a way to reduce electrical demand for mechanical cooling as the absorption cooling technology is driven not by electricity, but by a heat source. As the district heating in Växjö is based on biomass, the absorption cooling will be driven by the biomass district heating from a CHP plant. The additional heat demand from cooling will make it possible to produce electricity during the summer period by the CHP plant. This has not been possible previously due to too low heat demand in the summer. In the same time the climate change will increase the cooling demand during the year and will prolong the cooling season while the heating season is shortened.

This project aims mainly to provide new knowledge onheat driven cooling technology coupled with a biomass fired CHP plant, thus creating polygeneration based on renewable energy sources (RES). The interaction between the load curves for the three products (heating, electricity and cooling) and its impact on technical conditions for optimal system performance are the key issues to be addressed. The added value (economical as well as environmental) of the polygeneration system as compared to an existing CHP will be assessed.

The project will consist of three different parts. In the first part, a minor demonstration cooler of 300 kW will be installed at the energy company offices. The operation started in June 2007, in cooperation with the Royal institute of technology (KTH) and, in the second part, it will be evaluated in order to obtain design criteria for a full scale cooler (2000 kW) at the University area. During the third part, a cooling plant will be built at Västra Mark in Western Växjö, in order to provide cooling for commercial buildings and the future office building in the town centre.
