The invention provides a heat recovery shell and tube condenser, which comprises a shell tube, a left header, a right header, heat recovery tube bundles and condensing tube bundles, wherein the shell tube is provided with a refrigerant inlet and a refrigerant outlet; two clapboards are arranged in the left header; the first clapboard is used for partitioning a left cavity into an upper cavity and a lower cavity; the second bent clapboard is used for partitioning a first cavity into a third cavity and a fourth cavity; three clapboards are arranged in the right header, and are used for partitioning a right cavity into fifth, sixth, seventh and eighth cavities from top to bottom; one end of a first group of heat recovery tube bundles is connected to the inside of the fourth cavity, and the other end of the first group of heat recovery tube bundles is connected to the inside of the fifth cavity; one end of a third group of heat recovery tube bundles is connected to the inside of the third cavity, and the other end of the third group of heat recovery tube bundles is connected to the inside of the sixth cavity; one end of a fourth group of heat recovery tube bundles is connected to the inside of the fourth cavity, and the other end of the fourth group of heat recovery tube bundles is connected to the inside of the sixth cavity; one end of a first group of condensing tube bundles is connected to the inside of the second cavity, and the other end of the first group of condensing tube bundles is connected to the inside of the seventh cavity; and one end of a second group of condensing tube bundles is connected to the inside of the second cavity, and the other end of the second group of condensing tube bundles is connected to the inside of the eighth cavity. Due to the adoption of the heat recovery shell and tube condenser, the refrigerant heat exchange time is increased, and the heat exchange efficiency is increased.
Description
technical field [0001] The invention belongs to the technical field of refrigeration and air-conditioning heat exchangers, and in particular relates to a heat recovery shell-and-tube condenser. Background technique [0002] At present, environmental protection and energy-saving products have become the mainstream direction of market development. Heat recovery chillers can make full use of the heat of the unit, use condensation heat to heat domestic water, provide domestic hot water while cooling, and reduce unit energy consumption. Heat recovery screw chillers The heat recoverer and condenser in the chiller play a key core role in recovering condensation heat to produce domestic hot water. [0003] Usually separate heat recovery device and condenser are used, the piping system is complicated, and there are many valves, which leads to an increase in the pressure drop of the system and reduces the energy efficiency of the system. Moreover, the overall shape of the unit is larg...
