The purpose of this project is to create a device that can pump 1kW of thermal energy between two separate loops of water.
The primary loop of water is the hot side and acts like any water cooling system. It has a pump, reservoir and heat exchanger to the air of about a 100W. However, there is also a front panel bulkhead port to allow the water loop to travel to larger radiators or (and here's the fun part) just have a continuous source of cold water from the tap flow through.
The secondary loop of water is thermally connected to the primary loop of water via two sandwiched "cold-plates" with 12 40mm Peltier heat pumps in the middle (a 1 kW heat-pump). Combined with the temperature controller, this allows me to set the desired temperature of the secondary water loop. The targeted range so far is 0-30C.
Once everything is up and running I should be able to practically dissipate over 500W with inlet coolant temperatures to the thermal source at 1C.
Both loops have a temperature/flow meter (with alarms) and there is another cut-off temperature controller watching the maximum temperature on the primary water-loop (pump is rated for 65C) that can cut the Peltiers/alarm).
I just wanted to do this for fun.
It also cost a LOT, so parts will be purchased very slowly and assembly will lag behind. Also, the parts list is mostly accurate (it's hard to be sure when you don't have most of them).
Hi , I am working on a similar project. I am gathering parts now. The plan is to have 5 peltier sandwiched between two aluminum, CPU water heat sinks. Each side will have it own pump, reservoir, radiator and fan. One radiator and fan will be inside a chicken coop and the other outside. The goal is for it to act as a heating and air conditioning system. In the winter the cold air outside will boost the heat and in the summer the outside radiator will be in the sun. A temperature controller will switch the polarity of the voltage to switch between cooling and heating. I didn’t want to do more than 30 amps to keep the electrical costs down. I will use a 12v 30 amp power supply. I also plan to fuse each of the peltiers for 6 amps did you consider that for your design?
