The invention discloses a component-adjustable carbon dioxide mixed working medium refrigeration/heat pump system. The component-adjustable carbon dioxide mixed working medium refrigeration/heat pump system is composed of a liquid separation condenser, a throttling valve, an evaporator, a compressor, a liquid storage tank and two control valves. Based on simple refrigeration/heat pump circulation, a branch is arranged at a bypass outlet of the liquid separation condenser, and the branch is formed by connecting the control valves and the liquid storage tank in series. According to the system, a mixed working medium composed of carbon dioxide and a refrigerant is adopted for circulation, through the design of the device, regulation and control operation of components can be achieved, the circulation components are matched with the refrigeration/heat pump system, and the better energy-saving effect is achieved. The system is mainly designed for the fresh air refrigerating and heating process of an electric automobile.
