OPERATIONAL RESEARCH OF ADSORPTION CHILLER AGGREGATE UTILIZING HEAT FROM DISTRICT HEATING TO PRODUCE CHILLED WATER FOR AIR CONDITIONING

The article contains the results of an experimental installation operating examination, aiming at proving the advisability of using an adsorption chiller aggregate to produce chilled water for air conditioning systems. The subject of the survey was an installation supplied from heat distribution network in the summer season, utilizing the network heat, which occurs in overabundance in off-heating seasons. The way of adsorption chiller aggregates functioning as well as the results of examinations on the influence of water temperature in supplying and discharging the heat from the aggregate on its refrigeration power and Coefficient of Performance have been shown in the article. The survey has been done for the range of network water temperatures up to 70 degrees C, which means typical for the off-heating season in most heat distribution networks in Poland. The received results indicate the possibility of utilizing, being in overabundance in summer season, network heat to supply adsorptive cooling appliances producing ice water for the needs of air conditioning.
