Yes, Dreaming is correct. While the capital cost is a lot higher than DX units (think central air compressors), they are often less expensive to run, last longer and provide very even temperature control when tied to water coils and valves.
For a residence, it ain't the Cadillac. It is a Bentley with an Aston Martin thrown in for when you only have one passenger. |

not quite.... the refrigerant is there, its just stuck in the chiller instead of being piped through the system. Not sure how this system is designed, but usually small chillers are air cooled, this makes them really loud in comparison to DX cooling. They must have a mechanical room underground or in a remote location to make the noise level balance out. Caddy, Bently, Aston Martin... good analogy |

Think about what is piped through large buildings!!!!!!! It's not a refrigerant but typically a chilled glycol. I'm currently working on a 500 ton system for process cooling as well as space cooling. Another way to look at it, that "box" next time you are at a motel/hotel, is not typically a "air conditioner" as you perceive. BTW, for a large complex, he was probably smart. Cheaper due to all the ductwork needed for a typical HVAC forced air system is not needed. It really comes to play when there are large distances between buildings. Have you though about the air handlers needed and the static pressure drops over long distances? That's not saying air handlers/coils are not needed but they supply a very local small area. The management system Steve installed is typical these days and has been for many years. Think about this, What happens when the sun is on one side of a large building and it's shaded on the other? |

I was going to make a redneck Chiller, pump or 40degree F Pump water that comes into the house though some pipes(about 50ft of 3/8 copper), and route our Cold Air return to run through it.
It was pretty hot in the northwoods this summer, so i rewired the furnace with a 5 wire programmable thermostart to just run the fan and it cooled the house about 5 degrees. Going from 81 to 76 really is nice. I put a big vent at the cold air return, so it would suck up the cold basement air, I just wanted to take this a step further haha. Or I can just build one of these lol. |
