An apparatus and method for cooling, air which apparatus includes an indirect evaporative cooler, a direct-contact ice-water chiller, a reheat coil component, an ice-thermal-storage component and an ice-manufacturing refrigeration chiller to provide alternative air-flow paths and alternative component combinations. The method provides alternative fluid-flow paths through electable combinations of the several components to effect the desired lowering of air temperature, relative humidity and air density in the cooled air.

A precooling system for combustion air communicated to a gas turbine, said system operable to receive ambient air at a wet bulb and dry bulb temperature, an ambient relative humidity and an ambient air density, and to provide said combustion air at a second temperature lower than ambient temperature

A precooling system for combustion air communicated to a gas turbine, said system operable to receive ambient air at a wet bulb and dry bulb temperature, an ambient relative humidity and an ambient air density, and to provide said combustion air at a second temperature lower than ambient temperature and a second density greater than ambient density, said system comprising: a direct-contact-air-chiller having a fluid-to-air exchange chilling media, ana ri inlet side, an air outlet side, a fluid inlet, a cooling fluid at a first temperature, and a sump for recovery of coolant fluid passing through said media from said fluid inlet passage, said direct-contact-air-chiller operable to receive air at an ambient temperature and density for reduction of said ambient air temperature and absolute humidity, and to increase said air density for communication to said gas turbine; means for reducing said cooling fluid temperature below said ambient wet-bulb temperature, which reduced-temperature fluid in said direct-contact-air-chiller is operable to reduce said ambient air temperature below said ambient wet-bulb temperature and to reduce said air absolute humidity; a pump, a first conduit connected between said pump and said fluid inlet for communication of said coolant fluid to said fluid-temperature-reducing means, which coolant fluid passes through said chilling media to cool said ambient air communicating through said chilling media from said inlet side for discharge from said outlet side; a first valve coupled to said sump and said fluid-temperature-reducing means, said first valve having a first servomechanism, a second conduit connected between said first valve and said fluid-temperature-reducing means; a second valve having a second servomechanism and coupled to said pump, said first valve and said fluid-temperature-reducing means, said first valve operable by said first servomechanism to communicate fluid from said sump to any of said second valve and said fluid-temperature reducing means, which second valve is operable by said second servomechanism to communicate said coolant fluid from any of said first valve and said fluid-temperature-reducing means to said pump for recirculating coolant fluid at a predetermined fluid temperature to said direct contact chiller for treating said ambient air.
