mendodistilling Posted January 13, 2015 Share Posted January 13, 2015 Design phase and I am putting in a horizontal series of holes. Any equipment suppliers or general input for hvac and warm preheated / chilled water or general design input or experiences? Link to comment Share on other sites More sharing options...
MG Thermal Consulting Posted January 13, 2015 Share Posted January 13, 2015 Couple different ways to go, depending on your locale. What State? Link to comment Share on other sites More sharing options...

Mash Posted January 13, 2015 Share Posted January 13, 2015 My advice is to contact a local HVAC/R contractor who has geothermal experience. The upside is efficiency and lower operating costs, but the capital cost may put it beyond reach. Horizontal holes in rock may or may not be the best approach. Having been a HVAC/R for 18 years in Florida, I could give you a lot of tips. But not knowing the geology, water source, and a million other details it would be a tough call on my part.

MG Thermal Consulting Posted January 14, 2015 Share Posted January 14, 2015 If your land supports it, putting a below ground cistern to hold glycol mix may be easier, and provide the same effect. I have a customer in MO who put a below ground poly cistern in and pipes the solution to a dry fluid cooler to recharge and another pump for the process and has run that way since the fall. I am waiting for him to ramp up production to see what the limits turn out to be and to gauge how long it will be until we have to add a chiller this summer ( South of St. Louis, gets hot in summer). I know others have done heat pumps where the hot water circuit is used for heating buildings. In colder climates up North, the idea is to run the dry cooler throughout the winter and at night during transitional periods and chiller the remainder of the time. Let me know if I can get more info for you. Mike Link to comment Share on other sites More sharing options...
mendodistilling Posted January 29, 2015 Author Share Posted January 29, 2015 Any down sides to using ethanol vs. Glycol? Link to comment Share on other sites More sharing options...
MG Thermal Consulting Posted February 2, 2015 Share Posted February 2, 2015 Using ethanol would mean anywhere there's piping going anywhere a spark can happen, you will need explosion proof rating for all electrical. Huge expense adder. Link to comment Share on other sites More sharing options...
