Marine anti-bumping refrigerating system and control method

The invention provides a marine anti-bumping refrigerating system and a control method, the marine anti-bumping refrigerating system comprises a compressor, a shell and tube condenser, a throttling device, a liquid accumulator and a vacuum pump which are connected in sequence, and the shell and tube condenser is provided with a first outlet. The liquid storage device comprises a containing cavity and a pressing plate; the pressing plate divides the containing cavity into a gaseous working medium storage cavity and a liquid working medium storage cavity located on the lower side of the gaseous working medium storage cavity. Micropores are formed in the pressing plate; a first working medium inlet and a first working medium outlet are formed in the liquid working medium storage cavity; the first working medium inlet communicates with the first outlet; the first working medium outlet is communicated with an inlet of the throttling device; a second working medium outlet is formed in the gaseous working medium sto
