The Cooled Room

Air conditioning moved populations into places the climate had refused, and the bill arrives as energy demand.

“New room? Good. We'll figure it out as we go — I'll try the doors.”
WH6-055 · The Cooled Room — Open the drawer
A self-contained window-mounted air conditioner from the 1950s, representing the first affordable cooling technology that enabled mass residential migration to hot climates and shaped modern urban settlement patterns.
WH6-056 · The Cooled Room — What is this thing?
A self-contained, room-scale cooling machine that mounted in a window frame, bringing mechanical climate control into American homes and offices during the postwar suburban expansion.
WH6-057 · The Cooled Room — Read the source
A personal letter written by a relocated family member in Phoenix, Arizona, describing the experience of moving to the desert Southwest and the role of air conditioning in making the relocation feasible and desirable.
WH6-058 · The Cooled Room — Map it / time it
A typical 1960s room air conditioner, the mechanical enabler of residential comfort in hot climates. Its adoption in Phoenix and the Southwest coincided with explosive population growth, making it central to debates about causation in climate migration.
WH6-059 · The Cooled Room — Two sources disagree
A window-mounted room air conditioner typical of 1960s Phoenix homes, representing the technology that enabled year-round comfort in the desert Southwest and became central to competing historical explanations of Sun Belt migration.
WH6-060 · The Cooled Room — State the claim
A mid-century residential window-mounted air conditioner, representative of mass-market cooling technology that made hot climates habitable for northern migrants seeking industrial and service jobs in the postwar Sun Belt.
WH6-061 · The Cooled Room — Take the other side
A period magazine advertisement for residential window air-conditioning units, showing installation in a suburban home. Represents the marketing moment when cooling became a consumer product rather than industrial necessity, arriving after postwar migration patterns were already established.
WH6-062 · The Cooled Room — Weigh it
A compact, self-contained cooling machine that fit into existing windows without structural modification. Its mass production and affordability made air conditioning accessible to middle-class households, enabling comfort in previously uninhabitable climates.
WH6-063 · The Cooled Room — Build the answer
A municipal utility graph plotting kilowatt-hour demand against population and cooling-degree-days, showing the tight correlation between air-conditioning adoption and power grid expansion in post-war Phoenix.
WH6-064 · The Cooled Room — For the file
A split-system air conditioning unit typical of mid-century Phoenix homes, representing the infrastructure that enabled desert urbanization and the energy-demand consequences that followed.
WH6-065 · The Cooled Room — Go and look
A representative 1970s–1980s split-system condenser unit mounted on a commercial building roof, showing the mechanical infrastructure that enabled rapid urban growth in hot climates and the energy demand that follows.
WH6-066 · The Cooled Room — Now, today
A split-system or window-mounted air conditioner typical of post-war American suburban homes, representing the technology that enabled mass migration to hot climates and now drives peak electricity demand during summer heat waves.
WH6-067 · The Cooled Room — Teach it back
A portable or through-wall air conditioner from the early postwar era, representing the first affordable cooling technology that entered middle-class American homes and enabled population growth in hot climates.
WH6-068 · The Cooled Room — The other place
A compact, self-contained cooling machine mounted in a window frame, representing the technology that enabled individual households and small businesses to inhabit hot climates without central infrastructure.
WH6-069 · The Cooled Room — One object, close
A representative 1960s window-mounted air conditioning unit, the technology that made year-round habitation feasible in hot-arid regions and enabled demographic shifts toward the American Southwest and South.
WH6-070 · The Cooled Room — Open the drawer
A single-room window-mounted air conditioner from the early 1960s, representing the first affordable cooling technology that enabled middle-class families to inhabit hot climates year-round without architectural redesign.
WH6-071 · The Cooled Room — What is this thing?
A self-contained room cooler designed for residential windows, representing the mechanical infrastructure that enabled post-war suburban expansion into arid and humid regions where settlement had previously been constrained by climate.
WH6-072 · The Cooled Room — Read the source
A technical instruction booklet for residential air conditioning units distributed by Carrier Corporation in 1962, assuming suburban home ownership, electrical infrastructure, and desire for year-round climate control as normal consumer expectations.
