Heat recovery refrigeration systems are a heat energy recovery and utilization system that generally includes a heat absorber (heat exchanger), a regenerator and a cooler. Its function is to achieve heat exchange between fluids of different temperatures. The focus of heat exchange system design is to enable the working fluid to have ideal flow characteristics, which requires that the designed components of the heat exchange system minimize the circulation resistance of the working fluid while meeting the heat exchange conditions. It is widely used in petroleum, chemical, power, refrigeration and other industries, and plays an important role in industrial production.

Heat recovery refrigeration systems are essential subsystems in the chemical process and are industrial auxiliary systems. In industry, heat exchange systems are usually used to provide energy for core process units and cool products to specified temperatures, reducing energy consumption in the chemical process. Improve energy efficiency. Heat recovery refrigeration systems usually consist of a heat absorber, a regenerator and a cooler. They can also be composed of multiple heat exchangers combined in a certain way to transfer heat between fluids. For example, when the temperature changes of two low-flow fluids are required to be large, a counter-flow combination of multiple heat exchangers can be used. This can, on the one hand, make the overall average temperature and pressure of the heat exchanger system larger, and on the other hand, due to Multiple smaller heat exchangers are used, which also brings convenience to the manufacture and arrangement of the heat exchangers. Therefore, the rational design and performance improvement of heat exchanger systems, which are closely related to the rational utilization of energy, are also problems often encountered in engineering. The energy recovered by the heat exchange system often has a higher energy level, but the utilization link itself has no energy sink to digest, such as the excess heat of the fractionation tower.

Heat recovery refrigeration systems can be divided into high-temperature heat exchange systems and waste heat utilization heat exchange systems. There are big differences in process parameters between the two. Since the high-temperature heat exchange system is used to cool down the working fluid or product, it has certain requirements for the outlet temperature, while the waste heat utilization heat exchange system has no restrictions. In terms of structural materials, heat exchangers in high-temperature heat exchange systems generally use heat-resistant alloy steel for the super-temperature heating surface and ordinary carbon steel for the lower-temperature parts to form a composite structure. As for the heat exchanger of the waste heat utilization heat exchange system, the flue gas discharged from the industrial furnace generally has a lower temperature, and the heat exchanger generally uses lower-priced carbon steel.
