Abstract
An evaporative heat rejection cycle for cooling a heat load is presented, including an environmental pre-cooling primary evaporator, an environmental pre-cooling secondary evaporator, a pre-cooled evaporative heat rejection cycle section in thermal communication with a heat load, and a primary pre-cooling evaporative heat exchanger in thermal communication with air that is drawn into thermal communication with a primary evaporator cycle, to enable heat transfer and moisture elimination from the air to a first fluid, where a portion of the first fluid evaporates and absorbs heat and condenses moisture from the air.

An evaporative heat rejection cycle for cooling a heat load, comprising:
- an environmental pre-cooling primary evaporator;
- an environmental pre-cooling secondary evaporator;
- a pre-cooled evaporative heat rejection cycle section in thermal communication with the heat load;
- and
- a primary pre-cooling evaporative heat exchanger in thermal communication with air that is drawn into thermal communication with the primary evaporator to enable heat transfer and moisture elimination from the air to a first fluid,
- wherein a portion of the first fluid evaporates and absorbs heat and condenses moisture from the air,
- wherein the first fluid transports the heat to a condenser where it is in thermal communication with a second fluid that at least partially condenses the first fluid,
- wherein the second fluid is circulated to a discharge pipe with atomizing spray nozzles that are in thermal communication with the air that is being pulled through a closed evaporative heat rejection chamber,
- wherein the second fluid is in contact with the air and creates a film on the fill or evaporator coil to enable partial water evaporation to the atmosphere as well as cooling the remaining first fluid as it travels down through a circuit in thermal contact with the air,
- wherein a portion of the cooled second fluid drops and collects at a cold water basin, and
- wherein the second fluid is circulated from the cold water basin and is pumped to the condenser to repeat the cycle.
A primary after-cooler evaporative heat exchanger in thermal communication with warm process heat rejection air is drawn into thermal communication with a primary after-cooler evaporator cycle, to enable heat transfer and moisture elimination from air to a first fluid, the heat exchanger enabling:
- a portion of the first fluid to evaporate and absorb heat and condense moisture from the air;
- the first fluid to transport heat to a condenser where it is in thermal communication with a second fluid that at least partially condenses the first fluid;
- and
- the second fluid to be circulated to a discharge pipe with atomizing spray nozzles that are in thermal communication with the air that is being pulled through a closed evaporative heat rejection chamber.
