This pic is one of the first successful attempts of converting the Honeywell Controler. By adding a analog circuit with
relay(s) the milivolt furnace controler commonly available in any home Depot or Lowes provides the requisite precise control
for regulating the internal temperature of the Valley Plastic Tm PC Computer covers. You set the temperature at the level with
the digital setpoint on the cool cycle. The Computer enclosure system has a primary and a secondary axial type cooling
fan. By experimentation were surprised that the enclosures work even better to combat dust bunnies in the shop. The
primary fan can be as low as 30 CFM 4.65 diameter the air flow is lower so less dust is being collected
by the air filter. The secondary fan will turn on automatically to cool the computer air plenum. So checkout
the video on the analog dust sensor.
I think you can get the idea that these two parts can be combined
novely and a digital signal convertor would provide an improvement over the software that is patented out there today for
the related class and subclasses. Of course the manifold for the top air filter intake section just drew the air from
the main filter through the inlet. The top section or cover is removed so you can see that. This cover had a set of cooling
fins shown in one of the pictures. For quiet operation and low noise the smaller fan is the primary fan and the larger fan
was the booster fan. In terms of costs the Honeywell offers the best options for dust particulate control because it
has its own digital computer with user friendly controls and costs less money than the what DustShield sells just a digital
thermometer. What is the point in knowing if its too hot in the box if you have to open the door the dust would get in. In
order for an unmaned remote mining operation or even a factory to operate 24/7 some basic electronics like this would be required.
So it was a step in the right direction.
