PURPOSE: A heat exchange cycle is provided to use a valve with many outlet ports capable of operating desired freezing cycle by valve switching mode by making easy to switch the valve by reducing refrigerant pressure on an inlet of the valve. CONSTITUTION: A cycle includes a compressor(32); a condenser(34); multiple evaporators(40a,40b); multiple capillaries(38a,38b); and a three-way valve(36). The capillaries are installed before the evaporators to decompress refrigerant. The three-way valve is installed between the evaporators to selectively open and close refrigerant pipings(35a) supplying the compressor and one of the evaporators with refrigerant having passed the other of the evaporators.
