NANOOK - open source DIY 19kW GWHP
Hi community, I just want to share my successful built of 19kW ground-water heat pump. It’s completely open source, incl. calculations, chassis drawing, schematics and control software.
Anybody who wants to clone the construction is highly welcomed! Here are some highlights: - 19kW heating power - 65°C / 149°F max. output temperature - r134a refrigerant - 950 meters ground loop - easy to build - 8 temperature sensors - 4 pressure sensors - 2 flow sensors - EEV (with supercapacitor backed up closure on power failure) - Panasonic/Sanyo scroll compressor - soft starter - 2 circulation pumps - onboard control system running Linux - configuration via web browser Image gallery: ownCloud 3D model: https://cad.onshape.com/.../e/8527985f7e35e0cf1587fe34 KiCAD schematics and PCB on my Github: https://github.com/burgrp?utf8=%E2%9...ype=&language= Looking forward to see your comments! |
