Claim 14:
15. A temperature control method executed at a temperature control device used for measuring thermal properties of materials, comprising:
receiving a set temperature of a test volume inside a test cell for measuring a thermal property of a sample when placed inside of the test cell;
determining a measured temperature of the test volume;
determining a difference between the set temperature and the measured temperature of the test volume; and
while a chill cell surrounding at least a portion of the test cell and separated from the test cell by a thermal break is being cooled by a cooling subsystem to remove thermal energy from the test cell through the thermal break, controlling supply of thermal energy to the test cell from a heating subsystem until the temperature of the test volume is equal to the set temperature, wherein the thermal break is configured to allow a controlled amount of heat transfer between the chill cell and the test cell.
