Since 2020, Meta’s hyperscale data center — spanning 50,000 square meters on an industrial estate on the edge of the city — has been pushing warm air generated by its servers into the district heating network under Odense. That heat is then dispersed through 100,000 households hooked up to the system, with Meta providing enough heat to cover roughly 11,000.
An AC can only cool the home, while a heat pump can both cool and heat a home. They are different things, and worth looking into.
That’s just an air conditioner. The difference between an air conditoner and a heat pump is that a heat pump has a reversal valve that allows the refrigerant to run backwards through the system.
My point is someone is using a whole bunch of words to say “I’d air-condition my server room”. It’s not exactly a ground breaking idea.
