Because that would violate the laws of thermodynamics.
Refrigeration-type A/C units work by exchanging the warm inside air with cold air using a heat pump/compressor. This is why the air immediately outside a window A/C unit is really hot.
Evaporative-type units run cold water past a set of fans, like a radiator. The now-warm water is then taken away, and re-circulated. The water can be initially cooled using a cooling tower (like at a nuclear power plant), or even a hybrid refrigerator system. (i.e. the water is cooled using a refrigerator system, like a water fountain)
TL;DR: If the cool air is let out, the temperature returns to equilibrium, according to the first law of thermodynamics and/or the law of conservation of energy.
But that wouldn’t matter to the warmists now, would it?

Precisely the point I’ve made numerous times about the heat that gets trapped by man’s piddly 0.001`37% CO2 contribution to the atmosphere- what little heat gets actually back radiated to earth will quickly return to equilibrium because it quickly becomes overwhelmed by cooler temps or warmer temps whichever the case may be-
The small amount of heat trapped by man’s CO2, and makign it’s way back to earth simply is NOT nearly enough to do ANYTHING regarding affecting the temperatures of earth
It is so small that it’s exactly like lighting a match in a football stadium, enclosed, once a year, and claiming that that one match affected the temperatures inside the stadium for the year- The truth is however that that match’s heat was quickly overwhelmed by the cooler temperature, and reached equilibrium temps almost immediately- with NO affect on the average temp In the dome
