自复叠热泵循环系统和自复叠热泵循环系统控制方法
The self-cascade heat pump cycle system, composed of a jet enthalpy-increasing compressor and a four-way valve, solves the problem that the self-cascade system can only operate in a single mode, enabling switching between cooling and heating and increasing capacity to meet high load demands and save costs.

AI Technical Summary
Existing self-cascade heat pump circulation systems can only perform either cooling or heating with a single set of piping, and their capacity is limited, making them unable to meet high-load demands.
A self-cascaded heat pump cycle system is constructed using components such as a vapor injection enthalpy-enhancing compressor and a four-way valve. The four-way valve switches the refrigerant flow direction to achieve the switching between cooling and heating, and the vapor injection enthalpy-enhancing compressor increases the evaporation pressure and condensation pressure to enhance the cooling or heating capacity.
It enables the switching between cooling and heating functions within the same piping system, enhancing cooling or heating capacity to meet higher load demands, saving piping costs, and improving the system's temperature control performance.
