[0002] At present, in the process of promoting energy conservation and emission reduction and rural coal-to-electricity conversion in the country, air source heat pump units have been widely used. However, the water flow required by the air energy main unit in the air energy system and the water flow required by the indoor terminal are different. The current existing products and installation methods cannot achieve reasonable hydraulic distribution, causing the air energy main unit and the terminal to operate in a low-efficiency state. In addition, the system installation is complex and there are many accessories. Construction workers are prone to make mistakes during installation, causing equipment failure or failure to achieve heating effects, and users cannot use the equipment normally. The current installation method has high professional and technical requirements, a lot of experience, and a high threshold for installers. Many practitioners who lack experience and technology cannot meet user needs, thereby reducing user experience, which is not conducive to the promotion of energy-saving products and creates unnecessary resistance to the country's implementation of energy-saving and emission reduction policies.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Reference Figure 1 , air energy high-efficiency hydraulic module, including a buffer water tank 10, an air energy circulation pump 6, an indoor circulation pump 2, a hydraulic distribution guide plate 8, a filter 7, an expansion tank 3, an automatic exhaust valve 4, and a drain valve 9;

[0017] The bottom circulation port of the buffer water tank 10 is connected to the filter 7, the filter 7 is connected to the air energy circulation pump 6, the air energy circulation pump 6 is connected to the air source water inlet, and is connected to the air source heat pump outlet with the upper circulation port of the buffer water tank; the water inlet of the indoor circulation pump 2 is connected to the water inlet of the buffer water tank 10 through a tee connection, the water outlet of the indoor circulation pump 2 is connected to the water inlet main pipe, the water inlet main pipe is connected to the floor heating 11 and the air disk 5, the floor heating 11 and the air disk 5 are connected to the water outlet main pipe, the water outlet main pipe is connected to the water outlet pipe of the buffer water tank 10, and a rotatable hydraulic distribution guide plate 8 is provided at the connection between the water outlet main pipe and the water outlet pipe of the buffer water tank 10, and a sewage valve 9 is provided at the bottom of the buffer water tank 10.

[0018] In this embodiment, a heat-insulating layer is provided on the buffer water tank 10 .

[0019] In this embodiment, the automatic exhaust valve 4 is arranged on the top of the buffer water tank 10 .

[0020] In this embodiment, the buffer water tank 10 is connected to the air energy unit 1 .

[0021] In this embodiment, multiple groups of floor heating 11 and fan discs 5 are provided.

[0022] In this embodiment, during operation, the air energy circulation pump 6 is turned on, and the heat-conducting medium extracted by the air energy circulation pump 6 flows out from the water outlet pipe after being heated or cooled by air energy. At the same time, the indoor circulation pump 2 is turned on, and the indoor circulation pump 2 directly extracts the medium heated or cooled by the host and sends it to the terminal for heating or cooling. The amount of medium extracted is based on demand, and the excess heat-conducting medium enters the buffer water tank 10; the medium that has completed heat exchange in the room flows through the terminal water outlet main pipe through the hydraulic distribution guide plate 8 and is mixed with the medium that has not participated in heat exchange in the buffer water tank 10 and then enters the air energy unit 1. The medium below the hydraulic distribution guide plate 8 is the medium that has completed heat exchange in the room, and the medium above In order to buffer the medium in the water tank 10 that does not participate in the heat exchange, the air energy enters through the air energy circulation pump 6 for heating. The upper and lower flow rates of the hydraulic distribution guide plate 8 are accurately distributed through the operation of the indoor circulation pump 2, which can minimize the flow rate of the medium that does not participate in the heat exchange, so that the temperature of the medium entering the air energy is closest to the temperature of the medium after the heat exchange at the end. The closer this temperature is to the temperature after the heat exchange, the higher the working efficiency of the air energy. The setting of the hydraulic distribution guide plate 8 can achieve accurate distribution of the unit flow and the terminal flow, and reduce the participation of the medium in the buffer water tank in mixing water, thereby improving the heat exchange efficiency of the system and saving about 5% of energy.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
