Study on Heating Performance of Transcritical CO₂ Air Source Heat Pump System

The traditional circulation system, ejector heat pump circulation system, flash evaporator circulation system, economizer circulation system, and expander circulation system are analyzed in typical heating conditions. The ideal warmth pump device form is achieved by designing the system with changeable operating conditions in mind. A brand-new kind of energy transfer system is created that can adapt to changing operating circumstances. The expansion work recovery technology and heat exchange supercooling technology are naturally combined in the new thermal cycle equipment. By modifying the system's on-off valve, the flow ratio of the air supply auxiliary circuit can be realized and the function of the different system operations can be realized to adapt to the complex working conditions of the heat pump. The system has good low-temperature adaptability and expands the application scope of CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> transcritical heat pumps. Finally, combined with the new system, the corresponding design interface program is developed, which makes it convenient and simple for the commercial calculation of the heat pump system.
