Abstract
The invention discloses a liquid storage tank of a carbon dioxide heat pump system. The liquid storage tank comprises a tank body, a support plate disposed in the tank body and an inlet pipe and an outlet pipe which are vertically fixed on the support plate. The support plate is provided with a plurality of clamp holes. One end of the inlet pipe is exposed out of the tank body while the other end of the inlet pipe extends to a central position in the tank body. One of the outlet pipe is exposed out of the tank body while the other end of the outlet pipe extends to an upper portion of the tank body. The end, located outside the tank body, of the outlet pipe is connected with a transfer pipe for transferring carbon dioxide. An oil outlet penetrating through into the tank body is reserved at the bottom of the tank body and connected to one end of a side transfer pipe for transferring lubricating oil. The other end of the side transfer pipe is connected to the transfer pipe. One side, close to the bottom of the tank body, of the outlet pipe is provided with an oil inlet which enables lubricating oil to be sucked into the outlet pipe. When a heat pump works, lubricating oil at the bottom of the liquid storage tank is sucked into the outlet pipe and the side transfer pipe under the siphon action.
