Could Somebody explain Positive Pressure vs

2016-7-15 · Positive pressure = more fans acting as intake than exhaust, think about it, they would BLOW into the case, increasing the pressure. Negative pressure = more fans acting as exhaust than intake, think about it, they would SUCK out the case, decerasing the pressure. Negative pressure is better for cooling because it eliminates any hot spots, but

How To Distinguish Positive And Negative Pressure

The coal-fired boilers studied at Plant Site 1 were operated under positive pressure (i.e. pressure within the boiler is higher than ambient pressure, often resulting in leaks of combustion gases and particles) and were not enclosed, while the coal-fired boilers at Plant Site 2 were balanced draft (i.e. pressure inside the boiler was similar to
