Efficient Solar air-conditioning and heating without the need for large batteries

Heating and cooling can consume up to 70% of a building's energy use, in off-grid settings this can requiring large batteries or generators. The system I have built enales the following criteria to be meet:

• Solar-powered

• Works after sunset without a large battery bank

• Locally sourced and low-tech

• Uses readily available, easily serviceable parts

• Reduces the volume of refrigerant gas

 

I initially created this system when working for an NGO in West Africa and later built another system in Australia. It's ideal for off-grid living, low-resource areas, or anyone wanting to cut energy costs.

​

The system is based on a frequency controlled inverter as well as using the concept of thermal storage in the form of water.
