Abstract:
An evaporative fluid cooling apparatus includes a cooling housing, at least two fluid coils, an air movement apparatus, and one or more spray apparatuses. The cooling housing defines a cooling chamber with an air housing input and an air housing output. The fluid coils are positioned in and extend across at least a portion of the cooling chamber in a spaced apart stacked arrangement. One of the fluid coils is positioned closer to the air housing output and has a first fluid input configured to be coupled to a fluid return from one or more air handler devices and a first fluid output coupled to a second fluid input to the other fluid coil. The other fluid coil is positioned closer to the air housing input and has a second fluid output configured to be coupled to a fluid supply to the air handler devices.
Abstract:
An air handler apparatus includes at least one heat exchanger device with a cooling fluid region separated from a temperature transfer fluid region, an evaporator device comprising an evaporator housing and at least one evaporator coil, and a pump. The cooling fluid region has a cooling fluid input and a cooling fluid output and the temperature transfer fluid region has a temperature transfer fluid input and a temperature transfer fluid output. The evaporator housing defines an air passage having an air input and an air output. The evaporator coil has an evaporator coil input coupled to the temperature transfer fluid output and an evaporator output coupled to temperature transfer fluid input of the temperature transfer fluid region in the heat exchanger device. The pump is coupled to the temperature transfer fluid region in the heat exchanger device to pump temperature transfer fluid between the temperature transfer fluid region and the evaporator coil when activated.
