A refrigeration system includes a main fluid loop and a secondary fluid loop. The main fluid loop includes a compressor and a heat exchanger that circulate a first working fluid. The secondary fluid loop circulates a second working fluid. The secondary fluid loop is in thermal communication with the main fluid loop at the heat exchanger. The secondary fluid loop includes a pump, a thermal energy storage, and a coil fluid line. The secondary fluid loop includes a multi-position valve configured to move between positions that selectively fluidly connect the heat exchanger, the pump, the thermal energy storage, and the coil fluid line.
