dc.description.abstract1Enhancement of gas turbine (GT) efficiency by inlet air cooling, known as TIAC, in chillers using the heat of exhaust gas is one of the most attractive tendency in energetics. A sustainable operation of GT at stabilized low intake air temperature is impossible without determining rational design cooling capacity of the chiller and TIAC system as a whole to match current duties without overestimation. The most widespread absorption lithium-bromide chillers (ACh) of a simple cycle is unable to reduce the GT intake air temperature below 15 °С because the temperature of its chilled water is approximately 7 °С. Deeper cooling air would be possible by applying a boiling refrigerant as a coolant in ejector chiller (ECh) as the cheapest and simplest in design. However, the coefficients of performance (COP) of ECh are considerable lower than those of ACh: about 0.3 against 0.7 of ACh. Therefore, the ECh is applied for subsequent cooling air less than 15 °С, whereas the efficient ACh – is for ambient air precooling to 15 °С. The application of absorption-ejector chiller (AECh) enables deeper inlet air cooling and greater effect accordingly. However, the peculiarities of subtropical climate, characterized by high temperature and humidity and thermal loads as result, require extended analyses to reveal the character of thermal load and modify the methodology of TIAC system designing, respectively. The advanced designing methodology that enables to reveal and thereby to forecast the peculiarities of TIAC system thermal loading has been developed to match those peculiarities and gain maximum effect without oversizing as result.
