A multi-connection refrigeration system having a natural cold source, and control method thereof. The system comprises at least one indoor refrigerating unit (10), at least one outdoor refrigerating unit (20), and a cold energy transfer unit (30) connecting the indoor refrigerating unit (10) to the outdoor refrigerating unit (20). The cold energy transfer unit (30) comprises a liquid storage device (31) for storing refrigerant, and a transporting pump (32) connected to the liquid storage device (31). The outdoor refrigerating unit (20) comprises a recuperative heat exchanging unit (21) comprising a first heat exchanging pipe (211) and a second heat exchanging pipe (212) independent of each other and used to exchange heat. The outdoor refrigerating unit (20) further comprises a compressor (22), a condensing device (23), a refrigerant pump (26) and a second control portion (25). The indoor refrigerating unit (10) comprises a first flow control valve (11), an indoor evaporator (12) and a first control portion (13). The indoor refrigerating unit (10), the cold energy transfer unit (30) and the first heat exchanging pipe (211) form a closed cycle. |
