Air-cooled generator is a type of generator that uses air as a cooling medium to dissipate the heat generated during operation. This type of design is prevalent in portable and standby generators. Higher operating
To reduce inlet air temperature of the gas turbine, an absorption cooling system is used, in which a heat-recovery steam generator is used to feed the chilling system. The results showed that using a lithium

An internal combustion engine works in 4 phases: Intake stroke: cool air inlet through the piston at the top, the intake valve opens, and the piston moves down and sucks the gasoline / air mixture from the intake manifold into
Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation. It may also improve the energy efficiency of the system.
Inlet air cooling improves performance of cooled gas turbine based combined cycle. Vapor compression inlet air cooling is superior to vapor absorption inlet cooling. For every turbine inlet temperature, there exists an optimum pressure ratio. The optimum compressor inlet temperature is found to be 293 K.
A novel inlet air cooling system for intercooled gas turbines is proposed. The proposed system is able to increase power output by 19% and efficiency by 2.3%. The novel system offers 8–18% better efficiency than existing designs in literature. The new system generates substantial annual profits.
It is important to note that the optimal inlet air cooling system for intercooled gas turbines can be selected through a thermo-economic analysis that factors in different ambient temperatures and the ISO relative humidity level of 60%.

The addition of inlet air cooling has been reported to enhance power by 3.9–25.7% and efficiency by 2.1–5.2% while the pay back period was increased by 3.7 years. Another promising inlet air cooling method is vapor absorption cooling, as it uses a low grade thermal energy source to drive the system and generate the cooling effect.
Increasing the inlet air temperature causes a reduction in the air mass flow rate, and the efficiency and output power of a gas power plant will reduced. To compensate this power and efficiency decrease, different cooling systems can be applied to the inlet air flow.
