Claim 1:
2. The refrigeration system with the direct expansion refrigeration mode and the refrigerant pumping energy-efficiency mode of claim 1, further comprising:
a first pipeline, wherein an end of the first pipeline is connected with the second outlet and an other end of the first pipeline is connected with the inlet of the evaporator assembly; and
a first one-way valve positioned on the cooling circuit, and located between the refrigerant inlet and a connecting node of the first pipeline and the cooling circuit, wherein the first one-way valve is configured to prevent refrigerant from flowing back to the refrigerant inlet when the refrigeration system is in the refrigerant pumping energy-efficiency mode, such that refrigerant flowing out from the outlet of the condenser assembly flows into the evaporator assembly through the first pipeline.
