Abstract: A refrigeration system includes a chiller with an integrated free cooling system and refrigeration system. In certain embodiments, the chiller may be a single package unit with all equipment housed within the same support frame. The chiller may generally include three modes of operation: a first mode that employs free cooling, a second mode that employs free cooling and implements a refrigeration cycle, and a third mode that uses the free cooling system to remove heat from the refrigeration system. A heat exchanger may be shared between the free cooling system and the refrigeration system to transfer heat from the refrigeration system to the free cooling system.
