Determine the amount of heat a recirculating chiller adds to a room

Air-cooled and water-cooled chillers put off heat to a room, but the amount varies depending on the type and amount of power used. This video shows you how to calculate and convert energy and process heat from use and helps you optimize your unit selection and placement in a room.
