Idk what chiller with air handler is, a refrigerant ac unit with the duct to window? I dont get it, I blow cold air into room from outside to bring air temps down. That doesnt remove latent heat unless I dehumidify it.

Honestly idk we will see how it goes, theres no harm in testing it. Its already on its way. I thought to keep ac just in case but really if it brings air temps down thats fine.

Im trying to understand and not be arogant. If you dont mind explaining more Im all ears and sometimes have to come back to stuff. But if it works thats all Im looking for here.

Exchanging air with the outdoors absolutely will affect latent heat if the air being brought in has a lower dew point.

Whats the advantage of a chiller and air handler vs mini-split, efficiency?

Efficiency is a unit by unit comparison.

A chiller makes water cold. That water needs to be pumped around a circuit which would include the chiller, whatever the chiller is cooling such as an air handler or RDWC water or whatever and some kind of reservoir for holding enough water in "cold" storage to allow the chiller to cycle off occasionally but not constantly.

As to whether a chiller system or mini split is better is a question that can only be answered on a case by case basis.

Its always humid around me like 80rh which is bad but its never raised rh in my room blowing air inside from outside. Neither would blowing air into room from the hallway open door with house rh at 60-80rh. That but it would be dehumidified coming in.

Contradicting myself a bit actually was about to say you cant just blow humidity or heat from one place to another. Though strategicly, like blowing air into room vs out of it seems to cool room rapidly so figured its about absorbing the heat like a ac unit does.

Regardless the things here tomorrow and Im testing it. I make bad searches that AI only embeds but I searched left and right, will this thing lower temps just a little bit..

Ok so I thought you meant water chiller but not sure what air handler is. Just using cold water to absorb the heat with a fan?

Idk but dont water chillers use the same amount of electricity almost as a ac unit aside from power surge.. I tried looking up nothing came up for chiller with air handler.

Ahh Im stressin about making it work Im fine regardless but yea Im pooped. I was warned to stay with my setup as is long ago or Il just be stressin left and right. Its cool though I prob wasnt expected to last this long and things are coming together ok.

In general, mini splits tend to be better for smaller scale and chillers scale up as big as you can imagine and probably bigger than that lol

You CAN get a big mini split with a central distribution unit and run a bunch of heads but at that point you're into the territory where a chiller setup is likely to be more flexible and cost effective.

A mini split sends pressurized refrigerant through the system which passes through some kind of expansion valve at the head unit and evaporated refrigerant returns to the compressor to be cycled again. Mini split units very often have variable frequency compressors which allow them to match speed to the load, improving efficiency. If some heads have a big load and others have very little, the system can compensate.

A chiller is a compressor like an AC unit that makes water cold instead of air. That water is then pumped around the system picking up heat and then back to the chiller to be cooled again. Usually a chiller system also has a reservoir to build up a store of cold water so the compressor can shut down for awhile, but not "short cycle" where it's kicking on and off every couple of minutes. This improves efficiency. Bigger chillers also have variable frequency drives to better match to the load.

Which one is right very much depends on the specifics of the application.
