PROBLEM TO BE SOLVED: To provide a refrigerating plant that can secure the reliability of parts by preventing an increase in pulsation and liquid compression which occur in a liquid injection circuit. SOLUTION: This refrigerating plant has a means which closes the liquid injection circuit before a compressor is stopped and another means which opens the liquid injection circuit after the compressor is started. Consequently, this plant can secure the reliability of parts by preventing an increase in pulsation and liquid compression which may occur in the liquid injection circuit.
