Abstract
Described herein is a refrigeration system that includes a first circuit, second circuit, and a coolant circuit. The first circuit is a natural cooling circuit and the second circuit is a mechanical refrigeration circuit. The first circuit includes a first evaporator and the second circuit includes a second evaporator. The coolant circuit passes through the first evaporator and the second evaporator in sequence. The coolant circuit includes a first bypass branch in parallel with the first evaporator, where a first control valve is provided on the first bypass branch. The refrigeration system has a smaller flow resistance in the mechanical refrigeration mode, thus effectively reducing the energy consumption of a coolant drive pump on the coolant flow path.
