摘要： PROBLEM TO BE SOLVED: To stabilize refrigerating cycle by setting the flow rate of refrigerant being fed to a load side heat exchanger at a specified shunt ratio, when a plurality of load side units are operated and regulating the flow rate finely depending on the magnitude of load. SOLUTION: A multi-type refrigeration cycle system comprises one heat source side unit X and two load side units A, B. When the load side units A, B are operated, load side controllers 14a, 14b of the units A, B receive signals from respective sensors and deliver required receiving items and calculation items to a heat source side controller 13. In cycle correspondence control, flow rate of refrigerant is finely regulated, by setting a shunt rate of refrigerant being fed to respective load side units A, B (load side heat exchangers 5a, 5b) based on the capacity ratio thereof. Consequently, deficiency of capacity or unstable supply capacity due to unstable refrigeration cycle caused by unbalance between the air side heat exchanging performance and the refrigerant side heat exchanging performance of the load side unit is avoided.
