摘要：
A method of temperature control in a cryogenic temperature control apparatus. The method includes operating the cryogenic temperature control apparatus in a first mode, and delivering a first flow rate of cryogen from a storage tank to an evaporator coil in the first mode. The cryogenic temperature control apparatus is operated in a second mode after operating the cryogenic temperature control apparatus in the first mode for a predetermined time duration. A second flow rate of cryogen that is lower than the first flow rate is delivered to the evaporator coil in the second mode.
