HZSS Supercritical CO2 Heat Exchanger | High-Pressure Resistant | Stainless Steel | Industrial Heat Pumps

The working principle of coaxial heat exchanger in supercritical carbon dioxide (SCO2) heat pump system is based on its unique structural design, mainly involving the process of transferring heat energy from one fluid to another. The working principle of supercritical carbon dioxide can be summarized as follows: 1 Structural features: Coaxial heat exchangers consist of two or more layers of concentric tubes, in which the inner tube (heat transfer tube) is used to circulate one fluid, typically carbon dioxide, at supercritical conditions, while the annular gap formed between the outer casing and the inner tube is used for the flow of another fluid, such as water or refrigerant. Heat transfer mode: heat transfer is mainly realized through heat conduction. Supercritical carbon dioxide experiences pressure and temperature changes in the inner tube, its physical properties are between liquid and gas, with high density and low viscosity, which greatly enhances its heat transfer capacity. The characteristic utilization of supercritical state. In the coaxial heat exchanger, this characteristic makes the heat energy transfer more efficient and continuous, without worry about the change of thermal resistance caused by phase change. The working principle of the coaxial heat exchanger in the supercritical carbon dioxide heat pump is to realize the efficient transfer of heat energy by making full use of the thermal physical characteristics of carbon dioxide under supercritical state and combining with the efficient heat exchange design, thereby improving the overall performance and environmental friendliness of the heat pump system.
