Air conditioners
What is air conditioning?
Air conditioning by definition is a means to cool and remove humidity from an environment, such as an enclosure, through use of a refrigerant cooling cycle. Air conditioners currently are the only practical standalone device in the market that can cool an environment below ambient temperatures. There are other devices in the marketplace that can cool below ambient (e.g. air to water heat exchangers), but these devices require a secondary coolant source supply to the unit, such as a chiller.
The impact of increasing temperatures
As technology in electronic packaging has advanced, so has the impact of thermal loading and temperature rise to these electronics. Smaller electronic components and increasingly dense packaging in enclosures have made these systems much more sensitive to external influences such as temperature, dust, oil and humidity.
This can be problematic because the failure of just one electronic component may lead to the complete shutdown of an entire production line. Resulting costs add up quickly.
