Air Exchange Heat Recovery by OTandAT
by Thingiverse
Last crawled date: 3 years, 3 months ago
This is a DIY air exchange with heat recovery that I'm using in my chicken coop. I'm using a DHT-22 humidity sensor to monitor the humidity and this system has a dual flow (inter/outer) tubes that recover the heat as the air is exchanged. Uses 6 inch PVC drain waste pipe and a 3.5 aluminum inter tube for the counter flow heat exchanger.
