PROBLEM TO BE SOLVED: To provide a refrigeration cycle that will not generate noise, when making a second evaporator start or stop during the operation of a first evaporator. SOLUTION: The refrigeration cycle, when making the second evaporator start or stop during the operation of the first evaporator, reduces the difference pressure between the inlet refrigerant pressure and the outlet refrigerant pressure of a solenoid valve for the second evaporator below that under the operation of only the first evaporator, before opening or closing the second evaporator solenoid valve.
