I Finally Built a Split-System Peltier Air Conditioner

Welcome to Summer 2026! I Finally Built an Entire Split System Using Peltier Modules! ⚡ CNC Machining and sheet metal start at just $1, new users claim the $123 welcome coupons from JLCCNC via: https://jlccnc.com/?from=InventorsDen In this video, I take my DIY Peltier Air Conditioner project to the next level and build a complete split-system AC using 8 TEC1-12715 Peltier modules, a custom CNC-machined water-cooled radiator, and an external heat exchanger to move the heat outside the room. The goal was simple: keep the cold side indoors, send the heat outdoors, and see if a Peltier-based air conditioner can actually cool a real room. For this build, I designed a custom radiator that acts as the heart of the entire system. The radiator was manufactured by JLCCNC and features a compact 120mm × 120mm footprint with a height of 120mm, allowing all 8 thermoelectric modules to transfer heat efficiently into a water-cooling loop. The system uses: • 8 × TEC1-12715 Peltier modules • Custom CNC-machined water block/radiator • Water cooling loop • Aquarium pump • Car radiator as the outdoor condenser • High airflow cooling fans • 12V power system TIMESTAMPS: 00:00 - Video Intro 01:01 - Radiator Preparations 03:19 - Radiator Assembly 04:28 - Platform Preparation 05:21 - Assembly On the Platform 07:26 - The Inside Fan 09:17 - The Front Grill 09:55 - The Outside Unit 10:58 - Attaching Pump 11:19 - Attaching Water Line 13:10 - Reworking the Waterline 14:36 - The Pump Issues 16:04 - Fixing Pump Problems 17:08 - Connecting the Power 17:32 - First Test 18:35 - Room Installation 19:38 - Test In The Room 20:45 - Temperature Readings 22:18 - Conclusions and Part 4 MUSIC USED: –––––––––––––––––––––––––––––– Music: Killing Time by Kevin MacLeod https://incompetech.com License: Creative Commons — Attribution 4.0 International — CC BY 4.0 Free Download / Stream: https://links.al/GKR Music promoted by Audio Library: https://links.al/youtube –––––––––––––––––––––––––––––– Music: Good Times by tubebackr / tubebackr License: Creative Commons — Attribution–NoDerivatives 4.0 International — CC BY-ND 4.0 Free Download / Stream: https://links.al/3Sv Music promoted by Audio Library: https://links.al/youtube –––––––––––––––––––––––––––––– Music: Told Me by LiQWYD / liqwyd License: Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://www.audiolibrary.com.co/liqwy...
