We nearly crash into the side of the duct as it makes a sharp turn to the right.
IRMA STAT: Alright, before we can cool the air, we have to get air to the air handler. We’re in the air return duct now. We should arrive at any moment. Prepare yourselves. Dive!
Right before we hit the end of the duct we plummet down a hole and head downwards. We somersault upwards. Directly in front of us is a giant, fibrous filter.
IRMA STAT: Not much gets through the filter ahead. COMPUTER: Initiating quantum phasing.
Colorful lights shoot all around us as a tiny hole appears in the filter. and we squeeze through it.
IRMA STAT: Hold steady!
In front of us, immense fan blades spin, threatening to dice anything that gets through their path. Wind whirls through the whole room.
IRMA STAT: We are in the Hyperion air handler. This blower moves over 1,200 cubic feet of air a minute. Unlike most air handlers it’s located at the bottom of the unit to generate positive pressures that prevent any leakage into the system. This will take an enormous amount of power. Everyone keep your hands and arms inside at all times!
COMPUTER: Initiating flux capacitor.
We hear a warping sound as time elongates and the fan blades slow to a crawl. Each one passes with a subsonic whir. We gingerly float past, narrowly missing a blade. We turn a corner. Ahead, two giant rows of coils diverge into a V-shape. The coils arc overhead in large horseshoe-shaped bends.
We feel a blast of cold air. The hoops of the coils are rife with condensation droplets, each one looking like an enormous glass boulder.
IRMA STAT: This is the heart of the air handler: where all the...
