A direct evaporative cooling system add-on to the existing air conditioning system for more effectively removing the Latent-heat-of-condensation of the refrigerant of the system greatly enhances the EER rating of the system. Upgrading the conventional air-conditioning systems from air cooled refrigerant-condensing-radiator to water-evaporative-cooling via an ADD-ON unit, comprising a reservoir that stores water to be periodically pumped up a pipe under pressure controlled by the electronic controller for timing and quantity. The water is sprinkling uniformly with the help of a plurality of holes in the pipeline wetting the condensing radiator, some of which evaporates cooling the radiator and the excess returning to the reservoir to be recycled over the radiator repeatedly allowing the evaporation and heat exchange process to continue. This cooling effect reduces the pressures required by the compressor at the same time reducing the power drawn from the electrical grid saving money on the electric bill and in turn reducing the carbon foot print created by the use of air conditioning.

The cooling systems and methods of the present disclosure involve modular fluid coolers and chillers configured for optimal power and water use based on environmental conditions and client requirements. The fluid coolers include wet media, a first fluid circuit for distributing fluid across wet media, an air to fluid heat exchanger, and an air to refrigerant heat exchanger. The chillers, which are fluidly coupled to the fluid coolers via pipe cages, include a second fluid circuit in fluid communication with the air to fluid heat exchanger and a refrigerant circuit in thermal communication with the second fluid circuit and in fluid communication with the air to refrigerant heat exchanger. Pipe cages are coupled together to allow for expansion of the cooling system when additional cooling capacity is needed. The fluid coolers and chillers are configured to selectively operate in wet or dry free cooling mode, partial free cooling mode, or mechanical cooling mode.

An integrated air conditioner comprises: a housing partitioned into a first housing on the upper side thereof and a second housing on the lower side thereof, wherein the first housing has a first intake port through which external air is introduced thereinto and a first exhaust port through which internal air is exhausted therefrom, and the second housing has a second intake port through which external air is introduced thereinto and a second exhaust port through which internal air is exhausted therefrom; a compressor provided in the interior of the housing to compress a refrigerant; a condenser that is provided on a second fluid channel, which connects the second intake port and the second exhaust port, and condenses the compressed refrigerant, supplied from the compressor, into a liquid phase; an expansion unit that expands the refrigerant, condensed in the condenser, into a low-pressure refrigerant; and an evaporator.

A system and method for the treatment and disposal of condensate, particularly acidic combustion condensate, are provided. A neutralizer connected with respect to a condensate flow can be used to treat the condensate flow to provide a supply of neutralized condensate to a transfer chamber. Neutralized condensate can be conveyed from the transfer chamber to an ultrasonic atomizer such as via capillary action by way of a wicking assembly. The ultrasonic atomizer is used to produce an atomized neutralized condensate that can be directly discharged or released at a controlled rate, decoupled from condensate generation, and appropriately disposed or utilized (e.g., humidification).

An air conditioner is provided, including an air flow path, a cooling unit disposed in the air flow path that cools air introduced into the air flow path to condense vapor contained in the air, and a humidification unit that humidifies the air and which includes a storage tank for storing water and a heater for heating water in the storage tank. A discharged-water storage unit is also provided, which stores water discharged from the cooling unit and water discharged from the humidification unit, and an exhaust pipe is connected to the storage tank and configured to discharge water in the storage tank to the discharged-water storage unit. An exhaust valve is disposed midway on the exhaust pipe, and an overflow pipe connects the storage tank and a part of the exhaust pipe on the downstream side of the exhaust valve.
