1. A method for dispensing gas, the method comprising:
dispensing a gas from a gas source at an initial temperature into a receiving vessel at a dispensing temperature, the dispensing temperate being within a first target temperature range and being lower than the initial temperature; cooling the gas from the initial temperature to the dispensing temperature during the dispensing step via heat exchange with a plurality of thermal capacitors arranged in series; circulating a refrigerant to each of the plurality of thermal capacitors using a refrigeration unit; and performing the circulating step for each of the plurality of thermal capacitors as a function of a measured temperature of each of the plurality of thermal capacitors and independently of whether the cooling step is being performed.
