1870's farm house gets chilled!

in THE MAIN WALL
Here's the chilled water system we built from scratch. Saved a ton of $$$ by doing it ourselves. Utilized a Flat Plate (made in York!) HX & indirect storage tank. Seer ratings more than doubled! Then it's just another hydronics job to run the chilled water to the air handlers.

    nice

    Mr yates,that is a nice setup.If you don't mind me asking is
    that your motor control mounted to the receiver,or a head
    pressure safety cutout? Nice move on adding the receiver,
    more storage capacity for pump down and helps out on flash
    gas. How many hats do you have Mr yates?

    It's

    Dave & the hats are many(G). Solenoid vlv for pump down & pressure switch is dual acting. The storage tank is the load "seen" by the condenser and it's a chill-on-demand system via activation from room stats that close the xx terminal end switch. A freeze stat resides within the diamond plate insulated HX hiding box and the intermediate loop is glycol/water. She purrs like a kitten(G) We can set the design tank temps and adjust the delta-T. Only one step removed from injection piping with outdoor reset!

    We intended to buy a system like this one, but the company quit making them unless you used their condenser and a combined outdoor storage unit the size of a walk-in freezer! Last year's RPA show saw me snopping around every single chilled water set-up to scavenge ideas(G).

    Beats the snot out of having a condenser farm and the hassles of exceeding freon line set length limitations. Then there's the oil traps and calculating increases in line sizing to (attempt) offsetting efficiency losses. Best of all, this set up saves the homeowners lots of buckage in operating costs.

    Then there's the radiant package we installed that finally brought comfort to this old farmhouse. Fodder for anuther schtory, but suffice it to say old man winter has been kicked in the pants!

    New well-water pump, filtration, UV and RO too. Potable PEX homerun system with re-circ to the remote manifold.
