摘要

In the past years district cooling systems are getting more and more on attention. The coolingrndevices, usually vapor compressor chillers, are part of the district cooling system. They produce therncooling energy, which is then on a demand distributed over the district network. In several cases thernabsorption chillers with the working pair lithium bromide - water are used also, depending on therncost and operation analysis of the system. Their limitation is the operation above the freezing pointrnof water, which does not allow us to store cold in a common way, in a form of ice.rnIn this paper the analysis of the use of ammonia absorption cooling devices in district coolingrnsystems will be presented. The comparison between the H2O-LiBr and NH3-H2O absorptionrndevices, as a part of a district energy system, will be made. Especially the possibility to usernammonia absorption devices over the night to storage cooling energy will be analyzed andrndiscussed. With this advantage is their use, if compared to H2O-LiBr absorption devices, in severalrnsituations more interesting and legitimate.
