DEVICE AND METHOD FOR CONTROLLING TEMPERATURE OF LOW-TEMPERATURE PUMP

摘要

Provided is a low-temperature pump enabling the maintaining of a preset temperature during a preset time, even when turned off. The low-temperature pump may comprise: a displacer which adjusts outside temperature by circulating a refrigerant existing therein; a thermal conduction part which transfers heat outside the low-temperature pump to the refrigerant; and a thermal conduction buffer part which, if the displacer is turned off, absorbs the heat outside that is transferred to the refrigerant, and uses same as energy for changing a state.
