Abstract
A refrigerating system include a heat management module, a direct cooling module, a plurality of heat exchange modules, and a plurality of cooling pipes. The heat management module may send, to the direct cooling module, control information that indicates that the charging pile needs to charge a terminal device. The direct cooling module may be configured to convert a gas refrigerant transmitted in a second pipe assembly into a liquid refrigerant, and transmit the liquid refrigerant to each heat exchange module and each cooling pipe through the first pipe assembly.
