Abstract: An evaporative cooling system includes a primary cooling unit that utilizes a cooling fluid flowing through a primary heat exchange medium to cool supply air flowing past the primary heat exchange medium, a bleed line and a secondary cooling unit disposed upstream of the primary cooling unit with respect to a flow direction of the supply air. The primary cooling unit includes a supply line for supplying the cooling fluid to the primary heat exchange medium, a reservoir for collecting the cooling fluid supplied to the primary heat exchange medium, and a pump for recirculating the cooling fluid collected in the reservoir back to the supply line. The bleed line bleeds a portion of the recirculating cooling fluid from the primary cooling unit. The secondary cooling unit includes a secondary heat exchange medium that receives the cooling fluid bled from the primary cooling unit through the bleed line.

Abstract: A system includes a high side heat exchanger, a flash tank, a vessel, a load, and a compressor. The high side heat exchanger removes heat from a refrigerant. The flash tank stores the refrigerant from the high side heat exchanger. The vessel includes a chamber defined by an exterior housing and a tube positioned within the chamber. Heat is removed from the liquid refrigerant circulating through this tube and coming from the flash tank. The load uses the refrigerant from the tube to remove heat from a space proximate the load. The load sends the refrigerant into the chamber between the exterior housing and the tube. The compressor receives the refrigerant from the chamber between the exterior housing and the tube and compresses the refrigerant.

Abstract: An apparatus comprises a subcooler, such as a vented tube/plate or tube on tube heat exchanger, and a pre-cooler and/or post-heater, which may be a vented tube/plate or tube on tube heat exchanger. The subcooler and pre-cooler and/or post-heater are connected in fluid communication with each other (in series) and with a refrigerant output and input of a condenser. For example, the refrigerant output goes into the subcooler, and the refrigerant input comes out of the precooler and/or post-heater. A working fluid (e.g. coolant), such as water or glycol or other working fluid, is forced, such as by pumping, first through the subcooler and then through the precooler and/or post-heater. Flow rate of the working fluid through the apparatus may be regulated such that the refrigerant is first subcooled to an incoming fluid's temperature and then to pre-cool the refrigerant to approximately its saturated-vapor state, when the system is operating to provide a refrigeration effect.
