AI Technical Summary
In existing air conditioning systems, the outdoor heat exchanger has an unreasonable subcooling section design in both cooling and heating modes, which leads to reduced cooling efficiency, poor heating effect, and inability to effectively recover waste heat from the refrigerant, affecting the system's operational stability and energy efficiency.
A heat exchange system comprising a main heat exchange component, a phase change heat exchange component, and heat pipes is adopted. By switching control valves, the refrigerant is subcooled and preheated in different modes. Heat exchange is carried out using phase change energy storage medium and heat pipes to improve system energy efficiency and stability.
In cooling mode, deep subcooling of the refrigerant is achieved to improve cooling efficiency and stability; in heating mode, preheating and anti-frost of the refrigerant are achieved to improve heating effect and system safety, while recovering waste heat from the refrigerant to reduce energy waste.
