摘要：
Experiments were run to compare an indirectly air-cooled commercial absorption chiller to a directly air-cooled absorption chiller prototype. Both were 4.5-kW, 1-m(3), single-effect LiBr-H2O chillers. The trials were conducted at outdoor dry bulb temperatures ranging from 28 to 37 degrees C. The maximum allowable generator inlet temperature in the commercial chiller (to prevent salt crystallisation) was 105 degrees C, while in the prototype it was 120 degrees C. The commercial chiller delivered chilled water at 18 degrees C and the prototype at 16 C. The mean daily COPth was 0.55 in the commercial chiller, compared to 0.62 in the prototype. The mean daily COPelec for the chiller and prototype was 3.5 and 5.3, respectively. The mean daily SCOP for the solar-powered air conditioning facility was around 0.08 in both cases.
