🔥❄️ Así ENFRIAMOS nuestra CASA sin usar AIRE ACONDICIONADO - POZO CANADIENSE o PROVENZAL.
Passive Air Conditioning System Explained
Overview of the Cooling System
- The system utilizes a buried pipe to cool children's rooms without electricity, resembling a Canadian or Provençal well.
- A hat is placed on the pipe to prevent water ingress, and a mosquito net is needed to keep bugs out.
Structure and Functionality
- Air intake leads into ducts that branch off to two separate rooms: Facundo's and Uma's. The air travels approximately 70 cm underground.
- The construction involved creating a trench about 6 meters long with homemade materials like bricks and ceramics for aesthetic purposes. Polyurethane foam was used for sealing joints effectively.
Technical Details of Construction
- A Roman arch was built over the ditch using cement earth bags, ensuring structural integrity as verified during construction in 2022.
- PVC pipes were avoided due to condensation issues; instead, T-junctions are used for drainage of any accumulated moisture within the system. This design prevents water buildup by directing it towards drainage wells.
Air Intake Location and Environmental Considerations
Optimal Placement for Efficiency
- The air intake should ideally be located in cooler areas with plants nearby, which help lower air temperature while providing clean air through natural processes. Plants act similarly to air conditioners by cooling the surrounding environment.
- For southern hemisphere locations, it's recommended to place intakes on the south side of buildings; conversely, northern hemisphere placements should be on the north side for optimal airflow from cooler regions or gardens.
Understanding Convection Principles
- The system operates based on convection principles where cold air replaces warm air through suction-like effects rather than cold rising directly; this creates a temperature gradient beneficial for cooling rooms effectively.
Air Conditioning Systems: Depth and Efficiency
Understanding Air Conditioning System Depth
- The speaker discusses the misconception that air conditioning systems must be installed at a depth of 2 meters, emphasizing that this is not a strict requirement.
- A specific example is given where a 110mm PVC pipe was used in a 2m deep trench, which proved ineffective for cooling an office space of approximately 12 m³.
- The speaker argues that larger pipes (at least 30 cm in diameter) are necessary for effective thermal stability, regardless of depth. Cement pipes are preferred for better performance.
- The recommendation includes installing a forced fan to enhance system efficiency if natural methods fail.
User Experience with Natural Air Conditioning
- UMA shares her positive experience with the natural air conditioning system, noting it keeps her room cool even on hot days.
- The speaker invites viewers to consider building similar systems at home and promotes community membership for guidance on sustainable living practices.
Community Engagement and Future Plans
- Information about joining the holistic permaculture community is provided, highlighting access to resources like the "Design Your Space" course for effective land use.
