Abstract

The invention discloses a heat exchange assembly and a refrigeration system with the same. The heat exchange assembly comprises a first shell tube type heat exchanger and a second shell tube type heatexchanger, and the first shell tube type heat exchanger comprises a first shell body, a first heat exchange tube and a secondary refrigerant communicating tube, wherein the first heat exchange tube and the secondary refrigerant communicating tube are located in the first shell body; and the second shell tube type heat exchanger comprises a second shell body and a second heat exchange tube positioned in the second shell body, the second shell body is connected with the first shell body, the second heat exchange tube comprises a second lower heat exchange tube body and a second upper heat exchange tube body, an inlet of the second lower heat exchange tube body communicates with an outlet of the first heat exchange tube, an outlet of the second lower heat exchange tube body communicates withan inlet of the second upper heat exchange tube body, and an inlet of the communicating tube communicates with an outlet of the second upper heat exchange tube body. According to the heat exchange assembly, the evaporation temperature of a first refrigeration system body where the first shell tube type heat exchanger is located can be obviously improved, the condensation temperature of the firstrefrigeration system body wherein the first shell tube type heat exchanger is located can be obviously reduced, and the unit energy efficiency ratio of the first refrigeration system body where the first shell tube type heat exchanger is located can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchange component and a refrigeration system with the same. Background technique [0002] In the related art, the shell-and-tube heat exchanger is widely used in various occasions of production and life, and is an important heat exchanger. The heat transfer of conventional shell-and-tube heat exchangers is restricted by the outlet temperature of the brine: the refrigerant in the evaporator absorbs heat from the brine, and the evaporation temperature of the refrigerant must be lower than the outlet temperature of the brine; The refrigerant releases heat into the refrigerant, and the condensation temperature of the refrigerant must be higher than the outlet temperature of the refrigerant. At present, the direction of heat transfer optimization is mainly to minimize the temperature difference between refrigerant saturation and brine outlet temperature. [0003] Due t...
