The present invention relates to a system and method of cooling by latent energy transfer and, in particular, to cool a fluid by discharging unwanted low temperature thermal energy to a surrounding ambient environment utilising a fluid evaporation process involving permitted or forced ventilation of air across a surface area of a heat transfer fluid. The invention further relates to an air treatment system utilising the cooled heat transfer fluid for cooling air and for supplying ventilation air to the evaporation process. A body of liquid is cooled close to the prevailing wet bulb temperature, discharging unwanted thermal energy to the surroundings, rendering the liquid suitable as a cooling medium for removing unwanted thermal energy from a location or in a process.

An air channeling sub-system may include a mechanical cooling section and a direct evaporative cooling section. The direct evaporative cooling section may be downstream from the mechanical cooling section. Cooling air is channeled through the air channeling sub-system and into the room. If a first set of control conditions is met, the air channeling sub-systems is operated in an adiabatic mode. The adiabatic mode includes channeling cooling air through the direct evaporative cooling section to evaporate water into the cooling air. If a second set of control conditions is met, the air channeling sub-system is operated in a hybrid mode. The hybrid mode includes channeling cooling air through the mechanical cooling section to remove heat from the cooling air and channeling the cooling air through the direct evaporative cooling section to evaporate water into the cooling air.

Steam cylinders for humidifies require periodic replacement as well as replacement to address failures etc. However, field replacement of steam cylinders is not a straight-forward operation and there is significant risk and potential for damage to the replacement cylinder and the humidifier as fluidic seals for the water inlet and steam outlet must be unmade as well as electrical connections for heater elements, level sensors etc. Accordingly, embodiments of the invention provide solutions for the deployment of replacement cylinders etc. for domestic, retail, and commercial systems that reduce the likelihood of damage to the fluidic seals, electrical connectors etc.

The electrical connections of a chamber or enclosure for a water tub can be protected through the use of spill element sensors. The spill element sensors can help to disable the delivery of power to the heater of a water tub in the event that the electrical connections become wet.

An air conditioning system sufficiently cleans an indoor heat exchanger by using moisture in indoor air even when a room is dry before operation. An air conditioning system includes an air conditioner having an indoor unit and an outdoor unit, a humidifier, and a controller. The indoor unit has an indoor heat exchanger and exchanges heat of the indoor air by passing the indoor air through the indoor heat exchanger. The humidifier supplies moisture to the room to increase a humidity in the room. The controller controls the indoor unit and the humidifier. In the cleaning mode, the controller controls the humidifier to raise the humidity in the room, and then controls the indoor unit to perform a cleaning motion of cleaning a surface of the indoor heat exchanger by generating dew condensation water on the surface of the indoor heat exchanger.
