Cooling and heating water simultaneously / System design

[energyeng16]

Hello everybody,

I have a problem understanding a system that provides hot water and very cool water simultaneously. Hot water is for heating puprposes and for the production of sanitary hot water (swimming pool and bath). Cool water is for buildings' air conditionning.

The core system is composed of 2 condensors, 2 evaporators and 4 compressors. The heat transfer fluid circulating indide condensors, evaporatos and compressors is R500, water is transfering heat in the secondary loop.

I would like to understand what are the hot and cold sources in this system since it looks like a heat machine. What could be the principle of this system? And what kind of water chiller is it (if it's a water chiller indeed)?

It would help me to go on my researches, thank you.

Try looking at this.

In your case replace air with water and you will get there.

Thank you very much, Little inch.

Actually, while I was searching in the net for similar systems, I always found examples of air conditionning systems. I was dubitative at first but now I am pretty sure it's a water-cooled chiller.

That's OK. The issue normally is that for the cooling system to work you need a constant source of cool water to heat up to take the heat away. If you have a swimming pool maybe that will be enough water to circulate...
