How does a chiller work?

[hammcd]

ive tried to do a little research on this but most sites that sell these dont actually say how they work

does it need a continuous water supply to function...and if so does it have any rodi membranes in them or would u have to hook up an rodi to it...

or is it kinda like an ATO..does it function as an ato as well?

do you just refresh water in the chiller itself every so often?

thanks

From what I understand. There are coils within the chiller that is hooked up to a condenser along with a thermometer. You feed water through one end and water travels without the coils and the thermometer detects the temp and turns the condenser on or off. After the water travels through the coils it will exit out the outlet of the chiller and back into your tank.

So yes, you have to have a consent feed of water going through the chiller. You'll also need a pump to feed the chiller or you can feed it with a split from your return pump. I've seen some people feed it with their return pump and then from the chiller straight into the DT.

you pump water over a coil inside the chiller, if the temp of the water after the coil is higher then what you set it at, the chiller turns on and the coil gets cold which cools the water flowing over it.

same as the a/c in your house just with water instead of air.

ah ok so there are none that u just fill up like an ato?...they all have to have water pumped to them from another source?

Edit: instead of storing the water locally

There are also drop in models where you place the cooling coil in your sump, but none like a ATO.

there...

no chillers that I know of actually contain a reservoir of water..

They require tankwater flowing through them, so a feedpump frpm your tank/sump through the chiller back into your tank/sump.

The drop in coils aren't as effective but work similar to a heatcoil in a washing machine - only they would cool, instead of heat.

Yep, you need a feed from the sump to be constant. If you set up the pump to start only when your controller said it was needed, the water level would drop when it started running to fill the chiller.
