this is pretty bad. if your ac's cooling capacity was 3000W, your compressor only needs to be around 1000W. But you would need a 3000W of peltier to achieve the same level of cooling from thermoelectric cooling. this is pretty dumb.
This is a waste of time, money and resources, it may seem like a good idea but you dont know how many modules you need and they're gonna be more expensive, inefficient and consume more power than a f*cking compressor
