Abstract
A refrigeration cycle controls a second evaporator while a first evaporator is operating. The refrigeration cycle of the present invention makes a differential pressure between an inlet refrigerant pressure and an outlet refrigerant pressure of a second evaporator solenoid valve when starting or stopping the second evaporator during operation of the first evaporator smaller than the differential pressure when operating only the first evaporator, then opening or closing the second evaporator solenoid valve.
