[0002] As an efficient and energy-saving heating method, heat pump technology has shown extensive application potential in many fields that require hot air or hot water. For example, in the processing of agricultural products, heat pump technology plays an indispensable role. Taking the steaming process of agricultural products as an example, this process often requires a large amount of hot water as a heat source.

Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. If not specifically specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0030] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0031] The embodiment of the present application provides an air source heat pump device, including a compression component 1, an evaporation component 3, a first throttling component 7 and a condensation component 2. The exhaust end of the compression component 1 is communicated with the inlet of the condensation component 2, the outlet of the condensation component 2 is communicated with the inlet of the evaporation component 3, the first throttling component 7 is arranged in the channel where the outlet of the condensation component 2 is communicated with the inlet of the evaporation component 3, the outlet of the evaporation component 3 is communicated with the intake end of the compression component 1, the compression component 1 is provided with a gas supplement port, the air source heat pump device further includes a heat exchange component 6, a bypass channel and a shunt channel. The outlet of the condensation component 2 is communicated with the high-temperature medium inlet of the heat exchange component 6, the inlet of the evaporation component 3 is communicated with the high-temperature medium outlet of the heat exchange component 6. Along the medium transportation direction, the first throttling component 7 is arranged in front of the heat exchange component. The bypass channel communicates the low-temperature medium outlet of the heat exchange component 6 and the gas supplement port, and the low-temperature medium inlet of the heat exchange component 6 communicates with the channel between the high-temperature medium outlet and the inlet of the evaporation component 3 through the shunt channel, and the shunt channel is provided with a second throttling component 9.

[0032] The compression component 1 is used to suck in the refrigerant with low temperature and low pressure to make it a high-temperature and high-pressure gas.

[0033] High-temperature and high-pressure gas enters the condensation component 2, where condensation occurs, causing the gaseous refrigerant to turn into a liquid and releasing heat to the outside world to achieve the purpose of heating.

[0034] The evaporation component 3 is used to absorb heat from the outside world, causing the low-temperature and low-pressure liquid refrigerant to turn into a gas.

[0035] The first throttling component 7 is used to adjust the refrigerant flow rate and pressure entering the evaporation component 3.

[0036] The compression component 1, the condensation component 2, the evaporation component 3, and the first throttling component 7 can each select suitable devices from the prior art, and their structural working principles are well-known to those skilled in the art, so they will not be elaborated here.

[0037] The bypass channel is used to supply gas to the compression component 1, enabling the air-source heat pump device of this embodiment of the application to achieve jet enthalpy increase. The specific principle of jet enthalpy increase is well-known to those skilled in the art. Generally speaking, during the compression process of the compression component 1, intermediate-pressure gas is inhaled through the air supply port. This intermediate-pressure gas is mixed with the gas after primary compression, reducing the temperature of the compression chamber, increasing the gas density at the same time, and increasing the enthalpy value.

[0038] By supplying intermediate gas into the compression component 1 through the bypass channel, the risk of excessively high compressor exhaust temperature is reduced, and the working reliability of the air-source heat pump device is improved. Moreover, the applicable range of the air-source heat pump device is expanded. Further, the energy consumption loss is reduced, and the energy efficiency ratio of the air-source heat pump device is improved.

[0039] The heat exchange component 6 can be a plate heat exchanger. Of course, other suitable devices can also be selected from the prior art.

[0040] Under the action of the separation channel, the device forms a dual-path throttling system. After the liquid refrigerant entering the shunt channel passes through the second throttling component 9, its temperature and pressure decrease. Under the action of the heat exchange component 6, this part of the liquid refrigerant can exchange heat with the liquid refrigerant discharged from the condensation component 2, evaporate into a gas, and then be sent to the air supply port of the compression component 1 through the bypass channel to achieve the purpose of jet enthalpy increase.

[0041] In some embodiments, the refrigerant of the air-source heat pump device includes the R515B refrigerant.

[0042] The R515B refrigerant can operate in a high-temperature environment. By using the R515B refrigerant and reasonably setting the parameters of this device, hot air above 100 °C or a liquid-vapor mixture above 95 °C can be output.

[0043] In some embodiments, the first throttling component 7, and / or, the second throttling component 9 includes an electronic expansion valve.

[0044] The electronic expansion valve is convenient to be controlled by a processor. That is, by electrically connecting the first throttling component 7 and the second throttling component 9 to the processor respectively, the flow rate and pressure of the refrigerant can be intelligently adjusted, making the adjustment of the refrigerant more flexible and enabling it to automatically adapt to different working conditions.

[0045] The structure and working principle of the electronic expansion valve, the electrical connection method between the electronic expansion valve and the processor, the circuit for the processor to control the operation of the electronic expansion valve, etc. are well-known to those skilled in the art and will not be elaborated here.

[0046] In some embodiments, a first drying and filtering component 8 is provided in the shunt channel, and a second drying and filtering component 10 is provided in the channel connecting the high-temperature medium outlet of the heat exchange component 6 and the inlet of the evaporation component 3.

[0047] The first drying and filtering component 8 and the second drying and filtering component 10 are respectively used to dry the refrigerant in the corresponding channels to remove the moisture in the refrigerant. On the one hand, by removing the moisture in the refrigerant, the risk of corrosion of the metal components of this device can be reduced. On the other hand, by removing the moisture, the risk of moisture affecting the heat exchange efficiency of the refrigerant is reduced. On the third hand, the risk of liquid hammer accidents occurring in the compression component 1 is reduced.

[0048] The first drying and filtering component 8 and the second drying and filtering component 10 can select suitable devices in the prior art, and their structure and working principle are well-known to those skilled in the art and will not be elaborated here.

[0049] In some embodiments, a gas-liquid separation component 5 is provided in the channel connecting the outlet of the evaporation component 3 and the intake end of the compression component 1.

[0050] The gas-liquid separation component 5 can separate the gas and liquid of the refrigerant entering the compression component 1, reducing the risk of damage to the compression component 1 caused by liquid hammer.

[0051] The gas-liquid separation component 5 can be selected from existing devices. For example, it can be a common gas-liquid separator.

[0052] In some embodiments, a liquid storage assembly 4 is provided in the channel connecting the outlet of the condensation component 2 and the high-temperature medium inlet of the heat exchange component 6.

[0053] The liquid storage assembly 4 is used to store the refrigerant discharged from the outlet of the condensation component 2 and can balance the hydraulic pressure of the refrigerant, improving the operation stability of this device.

[0054] In some embodiments, the liquid storage assembly 4 includes a tank body 11, a cover body 12, and an opening and closing member. The tank body 11 is provided with an opening, the cover body 12 is covered on the opening, the cover body 12 is provided with a liquid outlet 25, and the tank body 11 is provided with a liquid discharge channel 17, and the liquid discharge channel 17 is inserted into the liquid outlet 25. The opening and closing member includes two oppositely arranged wall portions 13, the wall portions 13 are connected to the tank body 11, the wall portions 13 are provided with strip-shaped holes 14, the wall portions 13 are provided with shaft bodies 15, the shaft bodies 15 pass through the strip-shaped holes 14, the shaft bodies 15 are provided with first elastic members 16, and the first elastic members 16 of the two shaft bodies 15 are connected to the cover body 12.

[0055] The tank body 11 is used to store the refrigerant, the cover body 12 is used to seal the tank body 11, and the fixing method of the tank body 11 and the cover body 12 can be selected from existing methods. For example, the tank body 11 and the cover body 12 can be connected by bolts.

[0056] The liquid discharge channel 17 is inserted into the liquid outlet 25, so that the refrigerant in the tank body 11 can be discharged through the liquid discharge channel 17.

[0057] A filtering portion can be provided at the inlet of the liquid discharge channel 17 to filter the refrigerant.

[0058] The cover body 12 can also be provided with a liquid inlet 18, and the liquid inlet channel can be inserted into the tank body 11 through the liquid inlet 18 for inputting the refrigerant.

[0059] The shaft body 15 passes through the strip-shaped hole 14. On the one hand, it enables the shaft body 15 to move along the strip-shaped hole 14, and on the other hand, it enables the shaft body 15 to rotate relative to the shaft body 15.

[0060] The first elastic member 16 can be a spring.

[0061] The first elastic members 16 of the two shaft bodies 15 are connected to the cover body 12, that is, the cover body 12 is connected to the shaft body 15 through the first elastic member 16. On the one hand, it enables the cover body 12 to move along the strip-shaped hole 14 with the shaft body 15 and to rotate relative to the wall portion 13 along the axis. On the other hand, it enables the relative position of the cover body 12 and the shaft body 15 to be adjusted, so that the cover body 12 can cover the opening of the pipe body more closely, increasing the sealing performance of the cover body 12 covering the pipe body.

[0062] The cover body 12 is rotatably connected to the tank body 11 through the shaft body 15, and this structure is convenient for opening or closing the tank body 11. Under the action of the strip-shaped hole 14, the cover body 12 can move along the strip-shaped hole 14, which is convenient for the liquid discharge channel 17 to withdraw from the liquid outlet 25 of the cover body 12.

[0063] The first elastic member 16 can also be used to improve the sealing performance between the liquid discharge channel 17 and the cover 12. For example, the cover 12 can be provided with a sealing ring 20. The sealing ring 20 has a hollow structure and a medium is accommodated inside it. This structure enables the sealing ring 20 to better fit the liquid discharge channel 17 and increases the sealing performance of the liquid discharge channel 17.

[0064] A protruding portion 24 is provided on the inner wall of the sealing ring 20 away from the first elastic member 16. The protruding portion 24 causes the volume of the sealing ring 20 to increase in this area.

[0065] When the cover 12 is covered on the tank body 11, the first elastic member 16 can be in a stretched state, that is, the first elastic member 16 will generate an elastic force on the cover 12 to make it move in the direction close to the wall portion 13.

[0066] When the cover 12 is covered on the tank body 11, first pull the cover 12 to align the liquid outlet 25 of the cover 12 with the liquid discharge channel 17, and then move the cover 12 downward so that the liquid discharge channel 17 can be inserted into the liquid outlet 25. After the cover 12 is released, under the action of the first elastic member 16, the liquid discharge channel 17 generates a pressure on the protruding portion 24, causing the protruding portion 24 to be squeezed, and the other parts of the sealing ring 20 expand under the filling of the medium, so that the sealing ring 20 can closely adhere to the outer wall of the liquid discharge channel 17, thereby increasing the sealing performance.

[0067] In some embodiments, the strip-shaped hole 14 extends along the axial direction of the liquid discharge channel 17.

[0068] The strip-shaped hole 14 extends along the axial direction of the liquid discharge channel 17, enabling the cover 12 to move along the axial direction of the liquid discharge channel 17, which facilitates the liquid discharge channel 17 to withdraw from the liquid outlet 25 of the cover 12.

[0069] In some embodiments, around the inner wall circumference of the liquid outlet 25, the inner wall of the liquid outlet 25 is provided with an annular groove 26. Along the radial direction of the annular depression, a sliding hole is provided on the inner wall of the annular depression. The cover 12 is provided with a sealing component, which includes a first sealing portion 21, a second elastic member 22 and two second sealing portions 23. The first sealing portion 21 is inserted into the sliding hole. The liquid discharge channel 17 is provided with a thickening portion 19. From the side of the liquid discharge channel 17 close to the opening to the side far from the opening, the thickness of the thickening portion 19 gradually increases. The first sealing portion 21 abuts against the thickening portion 19. The second elastic member 22 connects the cover 12 and the first sealing portion 21. The two second sealing portions 23 are arc-shaped segments adapted to the annular groove 26 and are arranged in the annular groove 26 along the circumference of the annular groove 26. The first sealing portion 21 is arranged between the two second sealing portions 23. The first sealing portion 21 is configured to push the two second sealing portions 23 to rotate in the direction away from the first sealing portion 21 when moving into the sliding hole.

[0070] The first sealing portion 21 is inserted into the sliding hole so that the first sealing portion 21 can move radially along the annular groove 26.

[0071] Similar to the protruding portion 24 of the sealing ring 20, the thickened portion 19 is provided on the side of the liquid discharge passage 17 away from the first elastic member 16.

[0072] The second elastic member 22 can be a spring.

[0073] When the liquid discharge passage 17 is inserted into the liquid outlet 25 and moves within the liquid outlet 25, the first sealing portion 21 can contact the thickened portion 19, and under the action of the thickened portion 19, the first sealing portion 21 can be pushed into the sliding hole.

[0074] The thickness of the thickened portion 19 gradually increases, so that the thickened portion 19 can form an inclined surface, and this structure can increase the contact area between the first sealing portion 21 and the thickened portion 19, thereby increasing the sealing performance.

[0075] Along the circumferential direction of the annular groove 26, both sides of the first sealing portion 21 can be inclined surfaces, and the surfaces of the second sealing portion 23 opposite to the first sealing portion 21 can also be matching inclined surfaces, so that when the first sealing portion 21 moves into the sliding hole, the first sealing portion 21 can push the second sealing portion 23 to move.

[0076] When the cover body 12 is covered on the tank body 11, the liquid discharge passage 17 moves within the liquid outlet 25. Since the first sealing portion 21 and the second sealing portion 23 remain in contact, the first sealing portion 21 and the second sealing portion 23 can maintain a seal. As the distance between the tank body 11 and the cover body 12 decreases, the distance that the thickened portion 19 pushes the first sealing portion 21 to move increases, so that the sides of the two second sealing portions 23 away from the first sealing portion 21 can tightly abut. The first sealing portion 21 and the two second sealing portions 23 cooperate to be able to tighten the liquid discharge passage 17, increasing the connection strength between the cover body 12 and the tank body 11. At the same time, the first sealing portion 21 and the second sealing portion 23 can seal the gap between the liquid discharge passage 17 and the liquid outlet 25.

[0077] In the embodiment where the cover body 12 is provided with the sealing ring 20, it can be the thickened portion 19 squeezing the thickened portion 19.

[0078] In some embodiments, a sealing layer 27 is provided on the side of the first sealing portion 21 and the second sealing portion 23 close to the liquid discharge passage 17, and the sealing layer 27 of the second sealing portion 23 extends to the opposite wall surfaces of the two second sealing portions 23.

[0079] For example, the sealing layer 27 can be made of rubber material.

[0080] The sealing layer 27 can increase the sealing effect of the first sealing portion 21 and the second sealing portion 23 on the liquid discharge passage 17.

[0081] The sealing layer 27 of the second sealing portion 23 extends to the opposite wall surfaces of the two second sealing portions 23. On the one hand, it increases the connection strength between the sealing layer 27 and the second sealing portion 23. On the other hand, when the two second sealing portions 23 abut against each other, the sealing layers 27 of the two second sealing portions 23 are pressed against each other, so that the inner diameter of the circular structure formed by the sealing layer 27 can be reduced, further increasing the sealing effect on the liquid discharge channel 17.

[0082] The above embodiments only describe the preferred modes of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, variations, modifications, and substitutions made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
