How to Make a DIY AC Linear Air Conditioner Down to -15°C and a Heat Pump Up to +35°C

Demonstration of the operation and freezing process of a homemade linear air conditioner down to -15°C and a DIY heat pump with the ability to heat elements in reverse mode up to +35°C. Today I will tell you how to make a heat pump with your own hands that will condition the air within the range of -15°C to +35°C in reverse mode. You will need two aluminum angles of 15x15 mm. Mark two pieces, each 21 cm long. Cut them using a bimetal saw blade with 8% cobalt. Now, as you understand, we are making the air conditioner casing, so we proceed to make the plug to direct the air flow from the air conditioner in the right direction. Cut the aluminum at an angle and then carefully bend it. It turned out nice and neat. Use a 6.5 mm diameter copper tube. These tubes are used by professional installers of air conditioners, heat pumps, and other climate devices. Cut a piece 21 cm long with a tube cutter. Take a smaller diameter copper tube — 4.5 mm. Make marks every 12-15 mm on both tubes. Take a 1.5 mm drill bit and drill holes at each mark. Note that the holes should be drilled only through one wall of the copper tube; do not drill through the entire tube. Now we need a capillary tube with a thickness of no more than 1.5 mm and no less than 1 mm. Using any round base with a diameter of 0.5 to 1 cm, wind 2-3 or a maximum of 4 turns of copper tubing around it and cut them to make these blanks. I made seven pieces. Camping gas with an operating range of -15 to +35°C. Therefore, it will not be possible to achieve lower or higher cooling or heating temperatures, as the gas will stop transitioning from liquid to gas state and will lose its properties. Before starting the assembly of all the evaporator elements for the air conditioner, we needed to use a sewing needle to open all the pinched holes in the capillary tube, as the gas must pass through them. SEQURE S99 Soldering Iron Kit! This is what we need for high-quality and precise work! Working voltage DC9V-21V (2.5Ω), DC11-21V (5.5Ω). Maximum power up to 150W (2.5Ω), 75W (5.5Ω). Supports selecting protocols of PD/QC/DC/PPS. Heats up in just 2 seconds. Auto Sleep & Standby modes. 3 groups of default heating temperatures and one-key turbo boost heating mode. Temperature range: 122°F to 932°F (50°C to 500°C). CNC stainless steel with hollow-out design accelerates heat dissipation. Firmware upgradable. Link to the product with a discount for you in the video description! Apply special soldering acid and solder the evaporator elements hermetically. Proceed to make the condenser. We will also make it from a copper tube, but with a thickness of about 2.5 mm, winding it around a glass container with a diameter of 35 mm. 7-8 turns of the condenser coil will be enough to change the gaseous state inside the system to achieve cooling and heating according to the heat pump principle. Start assembling the aluminum ultrathin air conditioner casing. Connect the aluminum angles and install the turbine to cool the system and expel the air. Be sure to use special high-pressure tubes that are resistant to temperature fluctuations in the range of -15 to +40°C and are not corroded by harsh chemicals. Use a high-pressure pump. Diaphragm pumps are not quite suitable for making air conditioners they are not designed for high pressure. If you have tried with diaphragm pumps, tell us about your experience. Test the system without filling it; if everything works, you can proceed with filling. Before filling, use a large syringe and needle to remove all air from the system and create as much vacuum as possible. Only after that, fill the air conditioner to the maximum allowed by the tube system and compressor. When the air conditioner operates in cooling mode, the refrigerant evaporates in the heat exchanger of the indoor unit and condenses in the outdoor unit. When the air conditioner operates in heating mode, the refrigerant condenses in the heat exchanger of the indoor unit and evaporates in the outdoor unit. What do you think, what area can it cool or heat? See you in the next video! Bye-bye!
