Heat Transfer Apparatus with Ultraviolet Air Treatment

Abstract

In one aspect, a heat transfer apparatus including an air inlet, an air outlet, a fan assembly to generate an airflow from the air inlet to the air outlet, a heat exchanger to transfer heat to the airflow, and an ultraviolet (UV) light source operable to emit UV light and treat the airflow. The heat transfer apparatus further including an automated cleaning apparatus operable to clean an interior surface of the heat transfer apparatus and increase an intensity of UV light in the heat transfer apparatus. The automated cleaning apparatus has a controller configured to cause the automated cleaning apparatus to clean the interior surface of the heat transfer apparatus in response to a reduced airflow UV treatment effectiveness condition.
