Abstract
A calibration system for a climate system utilizing closed loop feedback and a phase change cell includes controlling a transfer rate of energy between a phase change cell and a thermal mass based on at least a temperature of the thermal mass. The transfer rate is controlled in order to control the temperature of the thermal mass and selectively move a material in the phase change cell through a phase change with transferred energy. In particular, the temperature of the thermal mass is controllable when the material is maintained in the phase change. A thermal sensor in the thermal mass may also be calibrated based on the temperature of a thermal sensor in the phase change cell during a predetermined portion of the phase change.
