A fan assembly is described comprising a refrigeration system, an airflow generator and a condensation collector. The refrigeration system comprises a first heat exchanger and a second heat exchanger. The airflow generator is for generating an airflow over the second heat exchanger, and the condensation collector is for collecting condensate that forms on the second heat exchanger.
