A multiple mode hybrid heat exchanger apparatus is disclosed. The heat exchange apparatus includes a frame assembly having a first end wall, a second end wall, a first side wall, a second side wall, an indirect heat exchange section, a spray system, an intermediate distribution basin, and a direct heat exchange section. A vertical passage is defined by the frame assembly and the direct heat exchange section. A lower air inlet is defined by a plurality of openings in the direct heat exchange section, and the lower air inlet is configured to provide an inlet for air into the vertical passage. The apparatus further includes a cold water collection basin and a fan to induce an airflow through the lower air inlet. The multiple mode hybrid heat exchanger apparatus is selectably configured to operate in an evaporative mode, a dry mode, and an adiabatic mode.

Multiple mode hybrid heat exchanger

An evaporatively cooled refrigeration system includes a refrigerant, a gas/liquid separator, an expansion valve in fluid connection to the gas/liquid separator, an evaporator to receive the refrigerant from the expansion valve, a compressor configured to compress the refrigerant in fluid connection to the evaporator, and a gas cooler in fluid connection to the compressor. The gas cooler includes an indirect heat exchanger to convey the refrigerant and facilitate heat from the refrigerant and a spray system to spray an evaporative coolant on the indirect heat exchanger. Evaporative cooling provided by the evaporative coolant on the coil is configured to cool the refrigerant below a dry bulb ambient air temperature.
