A sterilization and disinfection device includes a housing. A control board, a humidification water tank, a humidification water trough, an ultrasonic humidifier and an ozone water tank are provided inside the housing. The humidification water trough communicates with a humidification outlet through a humidification pipe. A humidification air input channel is connected to a humidification fan connected to a humidification air inlet. The ozone water tank is equipped with an electrolytic ozone generator. The ozone water tank communicates with an ozone gas outlet through an ozone gas output pipe and a mixing chamber. The ozone water tank communicates with a water filling port through a water filling pipe. An ozone fan is installed in an ozone air inlet. The control board is electrically connected to the button display panel, the ultrasonic humidifier, the electrolytic ozone generator, the ozone fan, the humidification fan and the power inlet, respectively.

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.

According to an exemplary embodiment of the present invention, a floating-type humidifier includes a lower body which has a buoyancy space formed along an inner edge to float in water and has a water inlet formed so that water flows into a lower center; an upper body formed with a hollow tube communicable with the water inlet; and supporter formed in an elastically deformable closed curve, in which the supporter is in contact with an upper end of the lower body and a lower end of the upper body to couple the lower body and the upper body to each other.
