Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and more specifically, to an air source heat pump condensation structure. Background Technology

[0002] An air source heat pump unit consists of four main components: an evaporator, a condenser, a compressor, and an expansion valve, forming a closed system filled with a suitable amount of working fluid. The basic operating principle of the unit is based on the reverse Cartesian cycle principle: the liquid working fluid first absorbs heat from the air in the evaporator and evaporates to form steam (vaporization). The latent heat of vaporization is the recovered heat. Then, it is compressed into a high-temperature, high-pressure gas by the compressor, enters the condenser, and condenses into a liquid (liquefaction), transferring the absorbed heat to the water that needs heating. The liquid working fluid then expands and depressurizes through the expansion valve, returning to the expansion valve to absorb heat and evaporate, completing one cycle. This process is repeated continuously.

[0003] In existing heat pump condensers, the condenser tubes are generally fixed inside the condenser. Over time, dirt easily accumulates on both the outside of the condenser tubes and the inside of the condenser. Because it is inconvenient to disassemble the condenser tubes and condenser, cleaning the dirt is very difficult and requires a lot of time and effort. At the same time, it is difficult to clean the dirt thoroughly, resulting in poor cleaning effect.

[0004] In view of this, we propose an air source heat pump condensation structure. Utility Model Content

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] An air source heat pump condensing structure includes a casing 1, a top plate 3 fixedly mounted inside the casing 1, a condenser pipe 6 mounted below the top plate 3, and a condenser box 5 mounted on the lower part of the top plate 3 outside the condenser pipe 6. A mounting frame 4 movably mounted inside the casing 1 to connect with the condenser box 5 is mounted inside the mounting frame 4. A fixing frame 7 is fixedly mounted inside the casing 1. A threaded rod 8 is rotatably mounted inside the fixing frame 7. Two oppositely oriented threads are provided on the outer side of the threaded rod 8, and threaded blocks 9 are fitted onto both oppositely oriented threads on the outer side of the threaded rod 8. Support blocks 10 are rotatably mounted on the upper side of both sets of threaded blocks 9. An L-shaped block 12 is rotatably mounted on the upper side of block 10. Two sets of L-shaped grooves 13 are opened on the lower side of the mounting frame 4 to engage the L-shaped blocks 12. A motor 11 is fixedly mounted on the outer side of the fixing frame 7. The power end of the motor 11 moves through the fixing frame 7 and is fixedly connected to the threaded rod 8. The two sets of support blocks 10 are rotatably connected by a pivot pin, thereby improving the overall strength of the support blocks 10. By adjusting the power end of the motor 11 to rotate in different directions, the mounting frame 4 and the condenser box 5 can be easily moved up or down. This facilitates the disassembly and installation of the condenser box 5, ensuring the installation stability of the condenser box 5.

[0029] Specifically, two sets of mounting posts 2 are fixedly installed inside the chassis 1. The other end of each set of mounting posts 2 is fixedly connected to the top plate 3. The mounting posts 2 can support and fix the top plate 3, thereby improving the installation stability of the top plate 3 and the condenser pipe 6.

[0030] Furthermore, an evaporator 14, a compressor 15, and an expansion valve 16 are fixedly installed inside the casing 1. A feed pipe 17 is fixedly installed outside the evaporator 14, and the other end of the feed pipe 17 is connected to the compressor 15. A feed pipe 18 is fixedly installed outside the compressor 15, and the outer end of the feed pipe 18 passes through the top plate 3 and is fixedly connected to one end of the condenser pipe 6. A return pipe 19 is fixedly installed at the other end of the condenser pipe 6, and the return pipe 19 passes through the top plate 3 and is fixedly connected to the expansion valve 16. A return pipe 20 is fixedly installed outside the expansion valve 16, and the outer end of the return pipe 20 is fixedly connected to the evaporator 14. The evaporator 14, the compressor 15, and the expansion valve 16 can continuously heat and cool the gas, achieving the effect of continuous recycling of heat energy.

[0031] It is worth noting that two sets of telescopic hoses 21 are provided on the outside of the condenser box 5. The outer ends of the two sets of telescopic hoses 21 are respectively provided with water inlet pipes 22 and drain pipes 23. Both water inlet pipes 22 and drain pipes 23 pass through the casing 1 and extend to the outside. Water inlet pipes 22 and drain pipes 23 are connected to the external water supply mechanism and the water return mechanism, respectively, so as to facilitate water supply to the condenser box 5 and facilitate the collection and reuse of heated water. The hoses 21 are connected to the condenser box 5 through quick connectors. Thus, when cleaning the condenser box 5, the condenser box 5 can be disassembled from the mounting frame 4 by separating the hoses 21 and the condenser box 5, further improving the convenience of cleaning the condenser box 5.

[0032] It is worth noting that a sealing block 24 is fixedly installed on the lower side of the top plate 3, and a sealing groove 25 is opened on the upper side of the condenser box 5 to connect with the sealing block 24. The sealing block 24 is inserted into the inner side of the sealing groove 25, thereby improving the sealing performance between the top plate 3 and the condenser box 5.

[0033] In addition, the fixed frame 7 has limiting grooves 26 on both sides for connecting threaded blocks 9. The limiting grooves 26 can limit the threaded blocks 9, so that when the threaded rod 8 rotates, the threaded blocks 9 can be driven to move along the threaded rod 8, thereby facilitating the movement of the support block 10.

[0034] Working principle: When compressor 15 is working, it compresses the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas enters the condenser tube 6 inside the condenser 5 through feed pipe 28. By releasing heat in the condenser tube 6, it can heat the water in the condenser 5. After releasing energy, it turns into a liquid and enters the expansion valve 16 through return pipe 19. Finally, it enters the evaporator 14 through return pipe 20. At this time, the pressure drops instantly and it turns back into a low-temperature, low-pressure gas. Then, the gas enters compressor 15 again through feed pipe 17. In the process, the whole cycle repeats continuously. When it is necessary to clean the dirt on the inside of the condenser box 5 and the outside of the condenser pipe 6, the motor 11 is turned on to drive the threaded rod 8 to rotate. At this time, the two sets of threaded blocks 9 sleeved on the outside of the threaded rod 8 move simultaneously along the threaded rod 8 under the limiting action of the limiting groove 26. When the threaded blocks 9 move, they drive the support block 10 to move. The support block 10 drives the mounting frame 4 and the condenser box 5 to move downward, so that the condenser box 5 and the condenser pipe 6 gradually separate until the condenser box 5 moves to a suitable position, so that the condenser box 5 and the condenser pipe 6 can be cleaned easily.
