A method by a controller of a cooling system includes calculating a difference between a first temperature of ambient air and a second temperature of pre-cooled air. The pre-cooled air is ambient air that has been cooled by water from a water distribution system before it enters one or more condenser coils. The method further includes determining that the difference between the first and second temperatures is less than or equal to a predetermined temperature difference, and in response, determining that the first temperature is greater than or equal to a minimum temperature. The method further includes, if the first temperature is greater than or equal to the minimum temperature, instructing the water distribution system to distribute the water to pre-cool the ambient air for a predetermined length of time and to disable the distribution of the water after the predetermined amount of time has elapsed.

An adjusting method to adjust the liquid discharge operation from a collection tank of a cooling tower, comprising the steps of: checking an activation signal of a discharge solenoid valve (EV) of the tank; detecting a flow value of the liquid flowing between an inlet mouth and a discharge mouth of the collection tank to allow a discharge operation of the liquid contained in the tank, wherein said discharge operation is allowed in correspondence of a detection of a flow rate value of the liquid flowing between an inlet mouth and a discharge mouth of the collection tank at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of the liquid flow rate value that is null or lower than said reference threshold value.

There is provided a cooling tower speed reducer that reduces a speed of rotation input from an input shaft to rotationally drive a cooling fan installed inside a cooling tower. The cooling tower speed reducer includes a seal member disposed between a shaft and a casing. The seal member includes a first member externally fitted to the shaft and a second member internally fitted to the casing. The first member includes a first member main body and a first lip portion provided on an outer periphery of the first member main body. The second member includes a second member main body with which the first lip portion comes into contact and second lip portions provided on an inner periphery of the second member main body to come into contact with the first member main body.

A single inlet/single outlet modular counterflow cooling tower having two heat transfer sections installed atop two cold water basin sections and below three fan sections, each heat transfer section having its own water distribution system and draining into its own distinct cold water basin section. The water distribution system can provide flow over both heat transfer sections or over only a single section. The center fan support section supports the mechanical drive system for the fan and has a sealing plate at its bottom for sealing the gap between the two heat transfer sections.

A cooling tower includes at least one cooling fan, a cooling tower fan, at least one indirect heat exchanger, a heat exchanger coil and a direct heat exchanger. All inner surfaces of the cooling tower, except for the indirect heat exchanger, are made from and/or include a non-porous material. The non-porous material is high-density polyethylene. The cooling tower is part of an indirect-direct evaporative cooling system and supplies cool air to a building structure or areas that desire cooling.

A cooling tower for an evaporative cooling system includes a cooling tower fan, a fan housing, at least one indirect heat exchanger and at least one air outlet located in a side or in a bottom of the cooling tower or in both a side and in a bottom of the cooling tower.

The present disclosure relates to a cooling tower having a fill media, water distribution system, plenum, and an ultraviolet (UV) light emitter. The water distribution system distributes water to the fill media. A flow of air passes through the fill media and past a flow of the water and out of the cooling tower via an outlet. The plenum is defined by a volume between the fill media and the outlet. The UV light emitter is disposed in the plenum and configured to inactivate or kill organisms in a drift.
