ABSTRACT:
Disclosed herein is an apparatus for liquefying refrigerant and generating a low temperature in which a low temperature state is provided by the utilization of the refrigerant adiabatic expansion. The refrigerant is jetted into an expansion chamber through a valve, and is subjected to adiabatic expansion thereby to provide a low temperature state in the expansion chamber. The refrigerant thus placed in the low temperature state and liquefied is mixed with the refrigerant in a tank, as a result of which the temperature of the refrigerant in the tank is decreased. The refrigerant is intermittently jetted into the expansion chamber at predetermined time intervals.
