Résumé

The objectives of this study were to analyse performance characteristics during partial load operation and to calculate the energy consumption of an H2O/LiBr absorption chiller with a capacity of 210 RT. The effect of the cooling water flow rate and cooling water inlet temperature on the absorption performance and energy saving is quantified during the partial load operation. It wa found that the performance of the absorption system was more sensitive to the change in inlet water temperature rather than the cooling water flow rate. Even if the cooling water flow rate is reduced to 60% of the standard value, the capacity is recovered if the temperature of cooling water decreases about 2 °C. The pumping power of cooling water is 4 times higher than that of a cooling tower during the partial operation mode and the pumping power of cooling water becomes more significant with decreasing partial load. It was concluded that when the partial load is in the range of 100-40%, the reduction of the required power by 23% can be realized by decreasing the cooling water inlet temperature by 1 °C.
