why no absorption cycle

Absorption AC would basically be "free" in terms of fuel consumption.
Some of my neighbors are still using refrigerators which use it.
They're horrifically inefficient, as far as input energy per net cooling effect.
Some use anhydrous-ammonia as the working fluid, deadly poison if it leaks.
'Industry'-scale Lithium-bromide chillers are boot-strapped onto the waste-heat side of natural gas-fired turbo-generators for refrigeration ( AeroStealth operated one by Solar Corp., at the University of New Mexico, at Las Cruces.
They'll also run off flat-plate solar collectors.
They're only for 'stationary' applications. No G-forces allowed.
