Introduction
The PC AirCon is a small, solid-state airconditioner designed specifically for cooling personal computers.
Waffer Technology Corp’s PC AirCon is a small, solid-state air conditioner designed specifically for personal computers. The PC AirCon uses a thermoelectric cooler (TEC) to chill room air, which is then blown into the PC enclosure.

Main Features
- Incorporates advanced thermoelectric technology
- Compact, blue LCD temperature monitor built-in
- Simple, flexible control options
- Easy installation

The heart of the PC AirCon is a thermoelectric cooler that operates on the Peltier effect. When a DC voltage is applied to the TEC, one side of the Peltier device gets hot and the other side gets cold. Waffer Technology has sandwiched a small TEC between two aluminum heatsinks, each with its own fan.

The fan attached to the hot-side heatsink pulls air in thru the top of the PAC 400 and blows it across the heatsink to cool the hot-side of the TEC. The fan attached to the cold-side heatsink pulls air in thru the bottom of the PAC 400 and blows it across the cold-side heatsink. In the process the incoming room air is cooled and then blown into the PC.



So this doesn’t create any condensation that would pose cause for concern? Clearly when dealing with electronics that is the last thing you want. And thus far, I can’t find an answer to this.
I mean, it’s from 21 years ago so I’m not surprised there’s little info on it.
