摘要： A refrigeration control method and a refrigerator. The refrigeration control method for a refrigerator comprises: acquiring the refrigeration state of a first evaporator and the refrigeration state of a second evaporator; when the first evaporator performs refrigeration, acquiring the temperature of a second compartment; when the temperature of the second compartment is greater than the starting temperature of the second compartment and the difference therebetween is less than a first preset threshold, acquiring the temperature of a first compartment and determining whether the temperature of the first compartment is less than a preset first reference temperature, the first reference temperature being calculated according to the starting temperature of the first compartment and a set adjustment temperature; and when the temperature of the first compartment is less than the first reference temperature, switching the refrigerator into a state where the second evaporator performs refrigeration.

摘要： The present invention provides a semiconductor refrigerator, which comprises: a liner; at least one semiconductor cooler; and a plurality of cold end heat exchanging devices, each of which is configured to allow the refrigerant to flow therein and undergo phase-change heat exchange to transfer cold from the cold end of the semiconductor cooler to the storage compartment of the liner. Each of the cold end heat exchanging devices has three refrigerant pipelines, each refrigerant pipeline having an evaporation section which is downwardly bent and extends in a vertical plane and has a closed tail end, the evaporation sections of the three refrigerant pipelines of each of the cold end heat exchanging devices being thermally connected to the rear wall and two side walls of the liner respectively. Energy efficiency of the semiconductor refrigerator is improved significantly.

摘要： The present invention provides a bent pipe for a fluid to flow therein, which comprises: a plurality of bent portions; a plurality of connecting pipe sections, each connecting two adjacent bent portions; and a retention member, which is successively fixed at different locations along the length thereof to the bent portions on the same side of the bent pipe. In addition, the present invention further provides a semiconductor refrigerator having the bent pipe. Since the bent pipe and the semiconductor refrigerator of the present invention have a retention member, at least some of the pipe sections of the bent pipe can be kept in the bent shape such that the bending angle of the bent pipe is kept constant and thus the refrigerant in the semiconductor refrigerator can flow reliably in the bent pipe and can be effectively evaporated or condensed.
