PURPOSE: A natural gas liquefying system is provided to facilitate compressing a small amount of natural gas at high pressure, and control a liquefying process by enabling the control of the flowing amount of the refrigerant while using a rated capacity of a refrigerant compressor. CONSTITUTION: A natural gas liquefying system comprises: a first heat exchanger(110) installed on a feed line(10), refrigerating natural gas passing through the feed line by heat-exchanging with a first refrigerant; and a first refrigerant circulation-supplying unit(120) circulation-supplying the first refrigerant to the first heat exchanger after refrigerating the first refrigerant, a first compressor compressing the first refrigerant, and controlling the amount of bypass of the first refrigerant to the first compressor. The first compressor is a reciprocating type compressor. |
