Solar powered air-conditioning from DuCool

A hybrid air-conditioning system running on solar thermal energy and/or electricity has been launched by DuCool.

The DuHybrid solar powered air-conditioning system is said to reduce the energy required for cooling by up to 60% compared to standard air conditioning. It uses solar thermal energy when available, and switches automatically to electric power when needed.

The system combines desiccant dehumidification with evaporative or geothermal cooling to eliminate the need for conventional mechanical cooling. The DuHybrid system can also be integrated with a cogeneration system and can be powered by other renewable energy sources or waste heat, according to DuCool.

When running on the renewable energy mode, which is the default mode of operation, the hybrid air-conditioning unit can generate over 20 TR (tons of refrigeration) of cooling and dehumidification using renewable energy sources such as solar thermal and geothermal water.
