Re: 3 year old house will not stay cool
said by Sly  :If you want to cool the condenser, then look for a unit called a desuperheater. This is a heat exchanger which hooks up to the condenser side and circulates cold water through it and then runs it to a water heater tank for pre-heat water. A desuperheater cools down the condenser which makes the heat pump run more efficiently and it uses that heat to heat your home's water... making your water heater more efficient as well. I run a boiler with a heat storage tank (insulated 1600 gallon tank) for my heating and domestic water. 1600 gallons is quite a few BTUs, and my goal, someday, would be to put in central air and instead of dumping the heat to the air, have it dump into my tank. It might well generate enough energy to satisfy my hot water needs. I could see having a loop that goes through my tank, then through the ground, then to the condenser. I get heat, the condenser sees 50 degree ground temperature.
Regardless, can you point me in the direction of a desuperheater for residential-type applications? I'm finding patent claims and industrial-type units. |

Actually I've been looking for them myself. There aren't many residential manufacturers of them for regular heat pumps. Most desuperheaters are found on geo-thermal heat pumps as an add on option.
Here are two that I found for regular air units... Don't know the prices though as their websites don't give any pricing information:

| That Turbotec Envior-Pak unit looks like quite the ticket!
Talk about win/win.... saves on air conditioning costs AND hot water expense. Wow... It's only a matter of time before this market takes off.

| Why is the first I've heard of these.... These clearly are a great way to make homes more energy efficient---- they hit the two biggest energy expenses in a home--- A/C and Hot water generation (well, not counting winter heating I guess.)
Real boon in the summer.

From what I can see, it's really just a heat exchanger, a circulator, and some controls. The controls maintain a hot water temp in the useful range (120+) by varying the flow through the exchanger.
A perfect system would be a heat pump (that dumps its heat into the ground--therefore very efficent) but with a desuperheater inline before the ground loop to create some hot water for free (less purchase price and electricity).
I've never understood dumping the heat into the air. The air is 100 and the ground is 50. Not to mention fan noise. |

| Yea, me neither. What you described is a ground source heat pump with a desuperheater option. They do exist but are very expensive to install...

I have access to a back hoe, I can run the ground loops. I plumbed my entire furnace setup, so I can tie in the desuperheater. I just need to find a kickass hvac guy to work with me on this. That's all. =) |
