Air Handling Unit (AHU)
An air handling unit uses blowers to circulate conditioned air and accepts returned air to be conditioned again. In addition to blowers, AHUs contain heat exchangers, which transfer heat between cool and warm materials. For example, when a space needs air conditioning, warm air from the space is returned to the AHU. This warm air is cooled by circulating a chilled liquid into the heat exchanger. This newly cooled air can then be blown back into the space.
