The invention discloses a heat exchange assembly and a refrigeration system thereof. The heat exchange assembly includes: a first shell-and-tube heat exchanger, and the first shell-and-tube heat exchanger includes a first shell, a The first heat exchange tube and the brine communication tube; and the second shell-and-tube heat exchanger, the second shell-and-tube heat exchanger includes a second shell and a second heat exchange tube located in the second shell, the second The shell is connected to the first shell, the second heat exchange tube includes a second lower heat exchange tube and a second upper heat exchange tube, the inlet of the second lower heat exchange tube communicates with the outlet of the first heat exchange tube, and the second lower heat exchange tube The outlet of the tube communicates with the inlet of the second upper heat exchange tube, and the inlet of the connecting tube communicates with the outlet of the second upper heat exchange tube. According to the heat exchange assembly of the present invention, the evaporation temperature of the first refrigeration system where the first shell-and-tube heat exchanger is located can be significantly increased, and the condensation temperature of the first refrigeration system where the first shell-and-tube heat exchanger is located can be significantly reduced. The unit energy efficiency ratio of the first refrigeration system where the shell-and-tube heat exchanger is located is 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...
