Abstract
A hybrid heat exchanger apparatus includes a direct heat exchanger device and an indirect heat exchanger device and a method of operating the same encompasses conveying a hot fluid to be cooled from a hot fluid source through the indirect heat exchanger device to a cooling fluid distribution system. The hot fluid to be cooled is distributed from the cooling fluid distribution system onto the direct heat exchanger device. In a hybrid wet/dry mode, ambient air flows across both the indirect heat exchanger device and the direct heat exchanger device to generate hot humid air from the ambient air flowing across the direct heat exchanger device and hot dry air from the ambient air flowing across the indirect heat exchanger device.
