The company has developed a carbon dioxide heat pump series multi-tank direct heat heating system, including: carbon dioxide heat pump unit and water tank, which is characterized in that: the water tanks are several and connected in series with each other, and there are two adjacent water tanks. cut-off valve; the water outlet of the carbon dioxide heat pump unit is connected with the first water tank, and the return water port of the carbon dioxide heat pump unit is connected with the terminal water tank; the water outlet of the first water tank is connected with the water inlet of the heating equipment, and the terminal water tank is connected with the inlet of the heating equipment. The water ports are connected; a tap water supply branch is also provided on the water supply branch between the carbon dioxide heat pump unit and the first water tank. The utility model has simple structure, convenient installation and adjustment, improves the stability of the unit, reduces maintenance and material costs, and improves the heat exchange efficiency of the transcritical carbon dioxide heat pump heat exchanger.
