Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning equipment, and in particular to an energy-saving air-conditioning device with a waste heat recovery mechanism. Background Art

[0002] Air conditioning equipment uses the compressor as its key structure to achieve dual effects of cooling or heating. Taking the heating process as an example, its essence is achieved through a reverse thermodynamic cycle, such as: the gas refrigerant is sucked into the compressor from the evaporator and compressed into a high-temperature, high-pressure gas. The high-temperature, high-pressure gas completes the heat exchange process with the indoor environment during the circulation process.

[0003] Because the overall volume of the air conditioner is relatively small and the gas transmission distance inside it is relatively short, the heat exchange time of the high-temperature and high-pressure gas is relatively short. However, the gas after heat exchange still has a certain amount of heat, and this part of the heat will not be "transferred" to the indoor space, but will flow back to the inside of the compressor again with the gas circulation process. As a result, there is a large amount of heat waste during continuous operation. The waste of heat can be understood as excessive loss of electrical energy.

[0004] This application proposes a solution to this problem. Summary of the Invention

[0005] The purpose of the present invention is to provide an energy-saving air conditioner with a waste heat recovery mechanism. Regarding the heating process in a commonly used air-conditioning structure, due to the limitations of heat exchange distance / time, the gas after heat exchange still has a certain amount of heat, but this part of the heat is not directly transferred to the indoor space. During its continuous operation, there is a problem of a large amount of heat waste, which indirectly increases the power loss.

[0006] The object of the present invention can be achieved by the following technical solution: an energy-saving air conditioner with a waste heat recovery mechanism, comprising a main unit housing, a heating component, and a HVAC pipe component, wherein an inner frame box is installed in an inner position of the main unit housing corresponding to the HVAC pipe component, and a first-order sleeve, a second-order sleeve, and a drive motor are installed in the inner frame box;

The first-section sleeve is provided with a return port on the outer wall corresponding to the lower side of the piston block, and the second-stage sleeve is provided with a water supply port on the outer wall corresponding to the lower side of the piston block.

[0009] It is further configured as follows: the HVAC pipe is U-shaped, and is linearly arranged along the outer wall of the heat exchange slot plate, and one end of the HVAC pipe is connected to the spiral flow pipe.

[0010] It is further configured that: both ends of the spiral flow tube respectively penetrate the external position of the first-order sleeve, and the both ends of the spiral flow tube are respectively configured as a commutation opening and a commutation outlet along the setting direction of the first-order sleeve.

[0011] It is further configured as follows: the setting direction of the heat exchange slot plate matches the setting direction of the HVAC pipe assembly, and the heat exchange slot plate is set to an upper port and a lower port along the setting direction of the HVAC pipe assembly, and the water supply port and the lower port, and the return port and the upper port are connected by a hose.

[0012] It is further configured as follows: a universal arm is installed on the upper end of the piston block, a movable curved rod is provided on the universal arm, the movable curved rod passes through the first-order sleeve and the second-order sleeve upward, and an arc-shaped curved arm is provided on the top end of the movable curved rod.

[0013] It is further configured as follows: the two end positions of the arc-shaped curved arm are movably connected to the top end position of the movable curved rod, and the end position of the driving motor transmission rod is connected to the middle end position of the arc-shaped curved arm.

[0016] The present invention has the following beneficial effects:

[0017] 1. A water circulation heat exchange process is added for the HVAC operation process.

DETAILED DESCRIPTION

[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: In the heating process of a common air conditioning structure, due to the limitations of heat exchange distance and time, the gas after heat exchange still has a certain amount of heat, but this part of the heat is not directly transferred to the indoor space. During its continuous operation, there is a large amount of heat waste, which indirectly increases power loss. The following technical solution is proposed:

[0029] Reference Figures 1 to 6 In this embodiment, an energy-saving air conditioner with a waste heat recovery mechanism includes a main unit housing 1, a heating component 4, and a HVAC pipe assembly 3. An inner frame box 2 is installed in a position inside the main unit housing 1 corresponding to the HVAC pipe assembly 3. The inner frame box 2 is installed with a first-stage sleeve 8, a second-stage sleeve 9, and a drive motor 6.

[0030] A piston block 15 is slidably mounted on the inner wall of each of the first-stage sleeve 8 and the second-stage sleeve 9. A piston assembly is provided in the piston block 15. A spiral flow tube 13 is installed in the inner position of the first-stage sleeve 8 corresponding to the lower side of the piston block 15. The inner spaces of the first-stage sleeve 8 and the second-stage sleeve 9 corresponding to the upper side of the piston block 15 are connected.

[0031] The HVAC pipe assembly 3 includes a heat exchange slot plate 5 and a HVAC pipe corresponding to the heating assembly 4. The first section of the sleeve 8 is provided with a return port 14 on the outer wall corresponding to the lower side of the piston block 15, and the second-stage sleeve 9 is provided with a water supply port 12 on the outer wall corresponding to the lower side of the piston block 15. The HVAC pipe is U-shaped and linearly arranged along the outer wall of the heat exchange slot plate 5. One end of the HVAC pipe is connected to the spiral flow tube 13. The two ends of the spiral flow tube 13 respectively penetrate the external position of the first-stage sleeve 8, and the two ends of the spiral flow tube 13 are respectively set as a commutation opening and a commutation outlet along the setting direction of the first-stage sleeve 8.

[0032] Solution Description: A brief description of air conditioning for heating is provided. Essentially, it is achieved through the circulation of refrigerant. When the air conditioner activates the heating function, the refrigerant is compressed into a high-temperature, high-pressure gas by the compressor. This process increases the temperature and pressure of the refrigerant. The high-temperature, high-pressure refrigerant gas enters the condenser (outdoor unit), exchanges heat with the outdoor air, releases heat, and condenses into a liquid. At this point, the refrigerant temperature drops, but the pressure remains high. For example, the relevant content of this invention: the heating component provides high-temperature, high-pressure gas, which is continuously transmitted through the HVAC pipe assembly 3 and exchanges heat with the indoor environment to achieve the purpose of heating.

[0033] It should be noted that the high-temperature and high-pressure gas will not transfer all its internal heat to the indoor environment after heat exchange. The gas after heat exchange still has a certain amount of heat and is returned to the compressor to be compressed into high-temperature and high-pressure gas again and perform the above-mentioned heating process. However, in the present invention, a first-stage casing 8 and a second-stage casing 9 are added for the flow process of the high-temperature and high-pressure gas to Figure 5 For example, the key is that the high-temperature and high-pressure gas after heat exchange continues to flow from the lower side of the spiral flow channel 13. For this purpose, it is necessary to add an appropriate amount of heat transfer fluid and other media to the first-order sleeve 8 and the second-order sleeve 9, so that the high-temperature and high-pressure gas after heat exchange will undergo secondary heat exchange with the heat transfer fluid and other media again, and the remaining heat in the high-temperature and high-pressure gas will be transferred to the heat transfer fluid and other media, so that the temperature of the heat transfer fluid and other media will rise to the required value. On this basis, the heat transfer fluid and other media after the secondary heat exchange will be added to the heat exchange slot plate 5, the purpose of which is to supplement the temperature of the HVAC pipe assembly 3 with the heat transfer fluid and other media.

[0034] Example 2: The overall water circulation process is described in combination with the technical solution in Example 1:

[0035] The setting direction of the heat exchange slot plate 5 matches the setting direction of the HVAC pipe assembly 3, and the heat exchange slot plate 5 is set to an upper port and a lower port along the setting direction of the HVAC pipe assembly 3. The water supply port 12 is connected to the lower port and the return port 14 is connected to the upper port through a hose. A universal arm 11 is installed on the upper end of the piston block 15. A movable crank arm 10 is provided on the universal arm 11. The movable crank arm 10 passes through the first-order sleeve 8 and the second-order sleeve 9 upward, and an arc-shaped crank arm 7 is provided at the top position of the movable crank arm 10. The two ends of the arc-shaped crank arm 7 are connected to the upper end of the piston block 15. The top positions of the movable curved rod 10 are movably connected, and the end position of the transmission rod of the drive motor 6 is connected to the middle position of the arc-shaped curved arm 7. The piston assembly is composed of a lead sinker 16 and a floating block 17. A guide rod is fixedly installed between the lead sinker 16 and the floating block 17. A movable channel corresponding to the guide rod is opened in the piston block 15. The lead sinker 16 and the floating block 17 in the piston assembly in the first-order sleeve 8 are arranged in a direction from bottom to top, and the lead sinker 16 and the floating block 17 in the piston assembly in the second-order sleeve 9 are arranged in a direction from top to bottom.

[0036] The following operation process is proposed for the technical content of Example 1:

[0037] S1: Figure 3 For example, the HVAC pipe is kept in contact with the heat exchange slot plate 5. On the one hand, it cannot affect the normal heat exchange process of the HVAC pipe. On the other hand, the heat in the heat transfer fluid and other media in the heat exchange slot plate can be used as a supplementary temperature in the heating process.

[0038] S2: The key point is Figure 5 and Figure 6 In the relevant content shown in the figure, in the initial state, the setting position of the piston block 15 in the first-order sleeve 8 is lower than the setting position of the piston block 15 in the second-order sleeve 9. During this process, it is necessary to ensure that the internal space of the heat exchange groove plate 5 and the first-order sleeve 8 and the second-order sleeve 9 corresponding to the lower side of the piston block 15 is completely filled with a heat transfer fluid or other medium. On this basis, the drive motor 6 is used as the power room to drive the arc-shaped crank arm 7 to deflect clockwise. The universal arm 11 and the movable crank rod 10 can refer to the crank arm structure in the automobile engine. No additional details are made in the present invention. It should be noted that: both the first-order sleeve 8 and the second-order sleeve 9 need to be kept vertically arranged;

[0039] This drives the piston block 15 in the first-stage casing 8 to move upward while the piston block 15 in the second-stage casing 9 to move downward. First, the piston assembly in the piston block 15 in the first-stage casing 8 will be explained: during its upward movement, the thermal fluid or other medium retained at the upper side of the piston block 15 in the first-stage casing 8 will generate a downward thrust on the float 17, thereby completely blocking the piston block 15 with the float 17, so that the thermal fluid or other medium retained at the upper side of the piston block 15 in the first-stage casing 8 can be replenished into the second-stage casing 9;

[0040] Similarly, when the piston block 17 in the second-stage sleeve 9 moves downward, the heat transfer fluid or other medium on the lower side of the corresponding piston block 15 of the second-stage sleeve 9 will generate an upward thrust on the floating block 17 inside it, causing the piston block 15 in the second-stage sleeve 15 to be in a blocked state, with the purpose of quickly injecting the heat transfer fluid or other medium in the second-stage sleeve 9 into the heat exchange slot plate 5;

[0041] S3: A temperature sensor is added to the space below the piston block 15 in the first-stage casing 8. Essentially, the heat exchange process in the first-stage casing 8 needs to be set in accordance with the heating temperature. After multiple heat exchange processes with high-temperature and high-pressure gas, the heat transfer fluid and other media are heated to a value that meets the requirements before being filled into the second-stage casing 9. It should also be noted that the flow of the heat transfer fluid and other media in the heat exchange slot 5 needs to be further restricted. The purpose is to ensure that the heat transfer fluid and other media that meet the requirements enter from the bottom side of the heat exchange slot 5, thereby increasing the heat exchange time of the heat transfer fluid and other media with the HVAC pipe assembly.

[0042] When the heat transfer fluid or other medium enters the first-stage sleeve 8, the heat transfer fluid or other medium flows upward through the active channel, which can be used to push away the floating block 17 in the piston assembly to ensure the flow process of the heat transfer fluid or other medium.

[0043] In summary: For the operation process of air conditioning and HVAC, an additional water circulation heat exchange process is added. Its essence is based on media such as heat transfer fluid. After the high-temperature and high-pressure gas passes through the heat exchange process of the HVAC pipe, it undergoes a secondary heat exchange with the heat transfer fluid through the spiral flow channel. The residual heat in the high-temperature and high-pressure gas is transferred to the heat transfer fluid and other media. After the temperature in the heat transfer fluid rises to the required value, the heat transfer fluid and other media that "accumulate enough heat" are replenished into the heat exchange slot plate through the synchronous movement process of the two piston blocks, and the flow mode of the heat transfer fluid and other media is further restricted. Its purpose is to: replenish the remaining heat in the heat exchange process into the HVAC pipe assembly and achieve the purpose of waste heat recovery in a water circulation manner.
