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.
