PURPOSE: A heat exchange cycle is provided to use a valve with multiple outlet ports capable of operating intended freezing cycle by valve switching mode by making easy to change 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); first capillaries(38a,38b); a three-way valve(36); and a second capillary(42). The first capillaries are installed before the evaporators to decompress refrigerant having passed the compressor. The three-way valve selectively opens and closes refrigerant pipings(35a,35b) supplying the evaporators with refrigerant having passed the compressor to open desired freezing cycle. The second capillary is installed before the three-way valve to decompress refrigerant flowing into the three-way valve. |
