HEAT RECOVERY TUBULAR - PIPE IN PIPE 2 If you print this project, and you are happy with the final part, do not forget to buy me a roll of filament - in order for me to be able continue to test and improve these projects or to design new ones! If you are not happy with this design or you have problem with your printed parts - send me a message, we will try to fix it together! :) If you do not want or you can't afford to buy me a roll of filament ... its ok, I still hope you enjoy printing my designs! Pace! Update 2nd Dec 2020 - upload same parts - new names - to avoid confusion... and low polly. Update 1st Dec 2020 - I print and install this system in to my quail coop, it is working great. I have a thermostat unit to control the system, just to not lower temperature more than 22 Celsius degree! It will require a drain system, since a lot of condensation is formed on the inlet aluminum tube! I will update as soon I design the drain system! Have the unit install few degree from horizontal, that condensation will accumulate on the end what is outside, therefore water will self drain to the outlet port. Use the provided parts. 5 Supports allow pipe to be lower at 4 meters length to 10mm. Not much, however it will do! Since air will be warm - chances that it will freeze are reduced, however at extremes temperatures is recommended to shoot down the system - if it get clogged with ice! The outlet line use two textile filters, in order to keep the quail dust out of the system. I am in process to printing a extra filter set - so I can replace those filters daily. Have same type of filter install on both lines - inlet/outlet - for an even pressure - if your room is very good sealed ! Some of the "old" parts are modified, so... in order to ensure that all parts are a "good to go" I erase all parts and upload the ones I use for my project! Enjoy! My quail coop have a 100mm isolation on the outside and pvc thermopannel door and windows, roof was isolated too, however, we remove the isolation to escape some mouse infestation... way back...so...anyway... the heat generated by the quail ... like +300 souls, manage to keep this room worm and cozy, no matter that outside are negative temperatures! For a workshop or a small barn. Fresh air without losing the heat. Not super esthetic, however, very efficient and easy to build. Design to use commercial PVC Drain pipes and fittings and reduced as much possible the use of 3d printed parts. The END's are "T" connections 160 - 110 mm. If HEPA filters are required, please see HEAT RECOVERY TUBULAR - PIPE IN PIPE for HEPA housing and connectors. https://www.thingiverse.com/thing:4105811 The heat exchange take place in a 160mm PVC drain pipe (thickness 3.2) and an extensible aluminum tube 100mm . Are two version of END CON, 1st one is full 3d printed and the 2nd one will require to cut a hole in 160 PVC plug and use 6 M4 16mm bolts. https://www.hornbach.ro/shop/Ramificatie-Valplast-PVC-160-110-mm-87/7409009/produs.html?sourceArt=7408966&url=7408966&trackArticleCrossType=pa https://www.hornbach.ro/shop/Teava-canal-Valplast-160mm-3m/7408966/produs.html https://www.hornbach.ro/shop/Mufa-canal-Valplast-PVC-160mm/7408994/produs.html https://www.hornbach.ro/shop/Dop-canal-Valplast-PVC-160mm/7409027/produs.html https://mathaus.ro/p/tub-aluminiu-100-3/000000000011111795?gclid=Cj0KCQiAjfvwBRCkARIsAIqSWlNtamy4JMNm9ZCjEraIEla8kAG0K67GS4kjpztjsquX6P7AaXs5DCYaAiPjEALw_wcB 2X120mm Fan - for inlet and outlet. Use same type of fans for an even airflow! Build your own air diffuser! For a wide spread of the fresh air see the sample with a 110 PVC pipe with holes in it (closed at one end). Over 100 holes (10mm) will take for a 110mm pipe to equalize the airflow! Use Spacers to center the aluminum pipe, secure those with aluminum tape to the aluminum tube - every 300mm. Aluminum pipe will be secured at the end terminations with a pipe clamp and aluminum tape. (If you do not have a pipe clamp, see the 3d printable model provided - it use a M4 - 18mm bolt/nut/washer.) All parts are check for naked edges or errors - therefore ... all are going to be printable! If the design is good or if the parts are going to fit... that's another story! Design to print without support ... mostly... except for the parts what need support :) By Costa
