GREENWAY ERV PROJECT
Interesting ERV project This is my own record of my ERV home ventilation project. By way of this blog I hope to share my wee project with people who are interested and keep a record for myself as well. The cost is considerably less then HRV's and ERV's on sale in New Zealand and it's been a really interesting project the study up on.
A BIT ABOUT GREENWAY
This is a blog about my ERV project. My background is in industrial automation and control systems and I have recently got interested in home automation. Our system is based on Arduino, Hubitat Elevation and MQTT. I have a gaggle of devices like Sonoff's and Arduino using MQTT, Thinger and occasionally Node-Red for experiments mostly. We wanted a low cost 150 mm system for our home using the most cost-effective parts we could find. I know its made of Coroplast and tape but if it works as I hope it will I will re-engineer some of the components in more durable materials.
THE PROJECT
There are 2 position-controlled valves 3 main fans, and 4 boost fans. Experiments show with a 6 Meter 150 mm duct and the main fan and boost fan at maximum we can get a flow in excess of 8 Cubic Metres per Minute.
Wondering, which uses the cloroplast channel or the spaced ducts?
I just scored 75ft of aluminum screen and already invested in just enough to iron into both sides of each cloroplast sheet I cut, albeit cut to rough shape rather embarrassingly crude looking since was outdoors in the cold winter a few months back. Thinking I might iron around the perimeter also, though obviously not the top or bottom.
