Purix’s solar air-conditioner is a sustainable alternative to conventional cooling. Powered by the sun, the air-conditioner reduces electricity consumption by up to 85%.

With global living standards improving, the demand for cooling — and corresponding energy use — will increase along with the negative environmental impact. In response to the growing need for alternatives, Purix designed a solar air-conditioner. Unlike conventional ACs, the Purix solar air-conditioner does not include an energy consuming compressor unit. Instead, solar thermal energy absorbed by solar panels produces water vapour, which is used by the Purix chiller as a refrigerant to produce chilled water that is distributed to cooling devices. The water returns to the chiller in a closed-loop system.

This solution was featured in Keeping it Cool market of the 2018 Global Opportunity Report, and was selected based on the criteria of that report. 

How the Global Goals are addressed

Good Health and Well-being

Alternatives to traditional ACs improve dry, unhealthy indoor environments and reduce noise pollution, increasing physical and mental well-being.

Clean Water and Sanitation

Despite converting solar heating into chilled water, the Purix air-conditioner does not require a water supply, and therefore contributes to sustainable water management.

Affordable and Clean Energy

By powering air-conditioners with the sun, Purix uses up to 85% less electricity than traditional air-conditioners, significantly reducing the strain on electric grids.
