Description

Technical Field

[0001] This utility model relates to the technical field of air source heat pump units, specifically to an air-source buffer water tank inner liner. Background Technology

[0002] An air source heat pump unit uses electricity to drive a compressor, which compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. The gas then releases heat through the condenser, transferring the heat to the water or air that needs heating. Finally, the refrigerant passes through a throttling device to reduce its pressure and temperature, returning to the evaporator to continue absorbing heat from the air, completing one cycle.

[0003] However, the water flow required by the air source heat pump unit and the water flow required by the indoor terminal are different. The existing products and installation methods cannot achieve reasonable hydraulic distribution, causing both the air source heat pump unit and the terminal to operate in low-efficiency conditions.

[0004] Therefore, an air source heat pump buffer water tank with a diversion inner liner was developed. The inner liner is designed with diversion pipes to achieve efficient distribution of hydraulic power within the system, which greatly improves the thermal efficiency of the main unit and the terminal. Utility Model Content

[0005] This invention provides an air-source heat pump water tank liner that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides an air-source heat pump water tank inner liner, comprising:

[0008] Buffer tank inner liner;

[0009] A filter, wherein the inlet end of the filter is connected to a circulation pipe installed on the outer surface of the bottom of the inner tank of the buffer tank;

[0010] An air-source heat pump, wherein the inlet of the air-source heat pump is connected to the outlet of the filter;

[0011] An air source heat pump unit, wherein the water inlet of the air source heat pump unit is connected to the water outlet of the air source circulating pump.

[0012] Through the above technical solution, the air source circulating pump draws the heat transfer medium from the inner tank of the buffer water tank through a filter into the air source unit for heating or cooling, and then into the inner tank of the buffer water tank, which supplies the underfloor heating and fan coil units respectively.

[0013] Furthermore, the inner liner of the buffer water tank includes a main return water pipe, which is installed on the inner liner of the buffer water tank. One end of the main return water pipe is located outside the inner liner of the buffer water tank, and the other end is located inside the inner liner of the buffer water tank.

[0014] Through the above technical solution, the main return water pipe can circulate the heat transfer medium and carry out heat exchange.

[0015] Furthermore, a diversion pipe is installed on the outer surface of the inner liner of the buffer water tank. One end of the diversion pipe is located outside the inner liner of the buffer water tank, and the other end is connected to the main return water pipe.

[0016] Through the above technical solution, the manifold can divert the heat transfer medium.

[0017] Furthermore, the outer surface of the inner liner of the buffer water tank is covered with an insulation layer, and an expansion tank is connected to the outer surface of the inner liner of the buffer water tank.

[0018] Through the above technical solutions, the insulation layer reduces heat loss from the inner liner of the buffer water tank, and the expansion tank balances the pressure.

[0019] Furthermore, a drain valve is installed on the lower surface of the inner liner of the buffer water tank, and an automatic air vent valve is installed on the upper surface of the inner liner of the buffer water tank.

[0020] Through the above technical solutions, the drain valve can discharge the sewage inside the buffer tank, and the automatic air vent valve can play a role in balancing the pressure.

[0021] Furthermore, the outlet of the air source heat pump unit is connected to one end of the main return water pipe, and one end of the branch pipe is connected to an indoor circulation pump. The outlet of the indoor circulation pump is connected to the floor heating system and the fan coil unit, respectively.

[0022] Through the above technical solution, the heat transfer medium exchanges heat with the indoor environment through the underfloor heating and fan coil unit.

[0023] Furthermore, the outlet of the underfloor heating and fan coil unit is connected to the circulation pipe.

[0024] Through the above technical solution, the circulation pipe and air-source circulation pump can circulate the heat transfer medium that has undergone heat exchange with the heat transfer medium that has not undergone heat exchange.

[0025] The above-described solution of this utility model has at least the following beneficial effects:

[0026] This invention utilizes an air-source heat pump to draw heat transfer medium from the buffer tank, which is then heated or cooled by the air-source heat pump unit. The medium flows out from the outlet and into the main return pipe within the buffer tank. An indoor circulation pump delivers the heat transfer medium to the underfloor heating system and fan coil units for heat exchange with the indoor environment. The amount of heat transfer medium drawn is based on demand, with excess medium remaining in the buffer tank. Heat transfer medium that has undergone heat exchange is circulated back into the circulation pipe from the underfloor heating system and fan coil units. Both heat transfer medium that has and has not undergone heat exchange re-enter the air-source heat pump unit for heating. This buffer tank unit precisely distributes the air-source heating or cooling medium directly from the distribution pipe to the indoor circulation pump. During this process, the air-source cooling or heating medium does not mix with the medium in the buffer tank, ensuring the medium at the optimal temperature is used at the terminal, improving terminal heat exchange efficiency, increasing the overall system energy efficiency ratio, and reducing the mixing of medium in the buffer tank, thus improving system heat exchange efficiency and saving approximately 5% of energy.

Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0033] like Figures 1 to 3 As shown, an embodiment of this utility model provides an air-source heat pump water tank inner liner, comprising:

[0034] Buffer tank inner liner 1;

[0035] Filter 2, the inlet end of filter 2 is connected to the circulation pipe 16 installed on the outer surface of the bottom of the inner tank 1 of the buffer tank;

[0036] Air-source circulating pump 3, the inlet end of air-source circulating pump 3 is connected to the outlet end of filter 2;

[0037] Air source heat pump unit 4, the water inlet of air source heat pump unit 4 is connected to the water outlet of air source circulating pump 3.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the inner tank 1 of the buffer water tank includes a main return water pipe 14, which is installed on the inner tank 1. One end of the main return water pipe 14 is outside the inner tank 1, and the other end is inside the inner tank 1. The main return water pipe 14 is divided into three branches: one branch is connected to the outlet of the air source heat pump unit 4 through a pipe; the second branch is connected to the branch pipe 15; and the third branch is connected to the inner tank 1 of the buffer water tank.

[0039] like Figure 3 As shown, a diversion pipe 15 is installed on the outer surface of the inner tank 1 of the buffer water tank. One end of the diversion pipe 15 is located outside the inner tank 1 of the buffer water tank, and the other end is connected to the main return water pipe 14.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, the outer surface of the inner tank 1 of the buffer water tank is covered with an insulation layer 11, and an expansion tank 13 is connected to the outer surface of the inner tank 1. The insulation layer 11 tightly wraps around the surface of the inner tank 1 of the buffer water tank, which can reduce the heat loss inside the inner tank 1 of the buffer water tank, and the expansion tank 13 plays a role in balancing the pressure.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, a drain valve 12 is installed on the lower surface of the inner tank 1 of the buffer tank, and an automatic air vent valve 17 is installed on the upper surface of the inner tank 1. The drain valve 12 can discharge the sewage in the inner tank 1 of the buffer tank, and the automatic air vent valve 17 can remove air to ensure the smooth flow of liquid in the pipeline.

[0042] like Figure 1 and Figure 2 As shown, the water outlet of the air source heat pump unit 4 is connected to one end of the main return water pipe 14.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, one end of the diversion pipe 15 is connected to an indoor circulation pump 5, and the outlet of the indoor circulation pump 5 is connected to the underfloor heating system 6 and the fan coil unit 7, respectively. The indoor circulation pump 5 introduces the heat transfer medium processed in the air source unit 4 into the inlet of the underfloor heating system 6 and the fan coil unit 7 through the diversion pipe 15, so that the underfloor heating system 6 and the fan coil unit 7 can exchange heat with the room.

[0044] like Figure 2 As shown, the water outlets of the underfloor heating element 6 and the fan coil unit 7 are connected to the circulation pipe 16. The heat transfer medium that undergoes heat exchange enters the circulation pipe 16 and, without heat exchange, is pumped by the air source circulation pump 3 through the filter 2 into the air source unit 4 for use.

[0045] Working principle: When this system is running, the air source circulation pump 3 is turned on. This air source circulation pump 3 draws heat transfer medium from the inner tank 1 of the buffer water tank, which is then heated or cooled by the air source unit 4 and flows out from the outlet into the main return water pipe 14 in the inner tank 1 of the buffer water tank. At the same time, the indoor circulation pump 5 is turned on. The indoor circulation pump 5 delivers the heat transfer medium heated or cooled by the air source unit 4 to the underfloor heating 6 and the fan coil unit 7 through the branch pipe 15 connected to the main return water pipe 14 for heat exchange with the room. The amount of heat transfer medium drawn is as needed, and the excess heat transfer medium remains in the inner tank 1 of the buffer water tank. The heat transfer medium that has completed heat exchange in the room circulates into the circulation pipe 16 through the underfloor heating 6 and the fan coil unit 7. The heat transfer medium that has not participated in heat exchange and the heat transfer medium that has participated in heat exchange pass through the filter 2 and the air source circulation pump 3 in sequence and then enter the air source unit 4 again.

[0046] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
