Abstract: A chiller system includes a mechanical-cooling circuit configured to circulate a refrigerant through an evaporator of the mechanical-cooling circuit, where the evaporator is configured to cool a conditioning fluid with the refrigerant. The chiller system also includes a free-cooling circuit configured to circulate the refrigerant through a heat exchanger of the free-cooling circuit, where the heat exchanger is configured to cool the conditioning fluid with the refrigerant. The chiller system also includes a distribution header having a first inlet configured to receive the refrigerant from the mechanical-cooling circuit, a second inlet configured to receive the refrigerant from the free-cooling circuit, and an internal volume fluidly coupled to the first inlet and the second inlet. A fan coil unit of the chiller system is configured to receive the refrigerant from the internal volume of the distribution header.

Abstract: Air cooled chillers have auxiliary heat recovery systems that include a heat recovery heat exchanger for transferring heat from a compressed refrigerant to a process fluid. According to certain embodiments, the air cooled chillers also includes a compressor, a condenser, an expansion device, and a controller to govern operations of the expansion device, a fan in the condenser, and other components of the chiller system. The controller may receive signals from temperature and pressure sensors located throughout the chiller system in order to determine a heat recovery load of the heat recovery heat exchanger. The controller may govern operations of the condenser fan and the expansion device according to a low heat recovery mode, an intermediate heat recovery mode, or a full heat recovery mode. In full heat recovery mode, the controller operates the expansion device based on subcooling detected in the heat recovery heat exchanger.

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.
