Description

Technical Field

[0001] The present invention relates to the technical field of air heat pumps, and particularly to an energy-saving air heat pump. Background Art

[0002] As an energy-saving device that relies on high-level energy to transfer heat from a low-temperature heat source to a high-temperature heat source, the core principle of an air-source heat pump is based on the reverse Carnot cycle. By using a compressor, the low-temperature heat energy in the air is converted into high-temperature heat energy, thereby achieving heating or cooling of the indoor environment. It has significant advantages such as high energy efficiency and environmental friendliness, and is widely used in the split system of room air-conditioning devices.

[0003] In the split outdoor unit of an air-source heat pump, the evaporator is a key component for realizing the heat exchange between air and refrigerant, and its performance directly affects the system energy efficiency. The evaporators in the prior art usually adopt a fixed-orientation air inlet structure, which can only obtain air from a specific direction (such as one side or both sides), and cannot make full use of the air flow in any direction around, restricting the improvement of the heat exchange efficiency.

[0004] Furthermore, there is a non-linear relationship between the air flow velocity (wind speed) and the heat exchange efficiency of the evaporator: when the wind speed is too low, the heat exchange between air and the evaporator surface is insufficient, and the amount of heat transferred per unit time is limited; when the wind speed is too high, the residence time of air on the evaporator surface is shortened, and the effective heat exchange amount decreases instead. However, in the prior art, there is a lack of a coordinated linkage mechanism between the air inlet volume adjustment mechanism of the evaporator and the fan power control, and it is impossible to dynamically adjust the cross-sectional area of the air inlet channel and the fan operation parameters according to the real-time wind speed, resulting in the evaporator being difficult to always be in the best heat exchange state. For example, in traditional designs, the fan usually operates at a fixed power, or can only be adjusted in stages through a simple wind speed sensor, unable to accurately match the dynamic changes of the air inlet structure, thereby causing energy waste or fluctuations in the heat exchange efficiency.

[0005] In addition, the air inlet structures of existing outdoor units are mostly fixed openings, lacking an intelligent mechanism for automatically adjusting according to the wind speed. When the external environmental wind speed changes drastically (such as in strong wind or calm weather), it is impossible to maintain a stable air flow velocity by actively adjusting the air inlet path or the opening size, resulting in a significant decline in the performance of the evaporator under extreme working conditions. Summary of the Invention

[0008] Further, arc-shaped elastic members are symmetrically fixed on both sides of the driven rod, and the other ends of the arc-shaped elastic members are fixed to the inner wall of the inner ring groove.

[0009] Further, telescopic grooves are symmetrically opened on both sides of the main board, auxiliary boards are slidably connected in the telescopic grooves in a limited manner, air intake elastic members are fixed between the auxiliary boards and the inner walls of the telescopic grooves, and electromagnetic adsorption pairs are arranged on the opposite sides of the auxiliary boards and the inner walls of the telescopic grooves; An electric anti-rotation ring for limiting the electromagnetic adsorption pair is embedded at the lower end of the top cover.

[0011] Further, the cleaning assembly further includes a piezoelectric ceramic sheet fixed on the blower assembly, the piezoelectric ceramic sheet is electrically connected with a resistive dust sensor through a capacitor assembly, and the resistive dust sensor is fixed on the windward surface of the heat exchange tube; A lifting ring is coaxially arranged inside the housing, and the lifting ring is in clamping fit with any one of the cleaning rings; The lifting ring is connected with a screw driving mechanism.

[0012] Further, clamping grooves are formed on the outer sides of the passive rings, sliding grooves are formed on the inner side of the lifting ring at positions corresponding to the clamping grooves, and clamping structures are arranged in the sliding grooves; The clamping structure includes a clamping and locking rod slidably connected to the sliding groove.

Detailed embodiments

[0019] In order to solve the technical problems that the evaporator of the existing split outdoor unit of the air source heat pump has limited air inlet orientation and the air velocity, air inlet volume and fan power cannot be coordinated and adjusted, on the one hand, the evaporator assembly 20 in the air heat pump is placed in the housing 10, and the main board 31 and the auxiliary board 32 are evenly distributed in a ring on the outer periphery of the housing 10 so that natural wind in any direction can enter the housing 10 through the space between two adjacent main boards 31 for natural heat exchange of the evaporator assembly 20. On the other hand, the auxiliary board 32 that is not affected by natural wind under normal conditions of this energy-saving air heat pump is in a fully extended state, and there is a relatively narrow air inlet between the two auxiliary boards 32 located between two adjacent main boards 31. When this energy-saving air heat pump is in a normal working state, the rotating sleeve 34 is in a free state. When natural wind in any wind direction blows towards the air inlet, it pushes the two auxiliary boards 32 to drive the rotating sleeve 34 to rotate. The rotating sleeve 34 rotates against the elastic force of the arc-shaped elastic member 38 and forms a dynamic balance with the wind force, and automatically adjusts the telescopic amount of the auxiliary board 32 relative to the telescopic groove according to the rotation angle of the rotating sleeve 34 to adaptively adjust the air inlet width, air inlet volume and the working power of the fan assembly 40.

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0021] Embodiment: As the technical background of this air heat pump: When the air source heat pump heats, the refrigerant with low temperature and low pressure in the evaporator assembly 20 evaporates, absorbs heat from the air and becomes gaseous, and then enters the compressor to be compressed into high-temperature and high-pressure gas; the high-temperature and high-pressure gas enters the condenser, releases heat to the outside and condenses into liquid, and the released heat energy is used to heat the medium; the liquid refrigerant passes through the expansion valve to throttle and depressurize, becomes low-temperature and low-pressure liquid or gas-liquid mixture, and enters the evaporator assembly 20 again, and so on in a cycle.

[0022] Refer to Figures 1 to 7 , an energy-saving air heat pump, including a housing 10, an evaporator assembly 20 arranged in the housing 10, an air inlet volume adjustment assembly 30, and a fan assembly 40. Through the mutual cooperation of the housing 10, the evaporator assembly 20, the air inlet volume adjustment assembly 30 and the fan assembly 40, the air inlet volume adjustment assembly 30 adaptively adjusts the size of the air inlet according to the natural wind intensity, and the fan assembly 40 adaptively adjusts its own working power according to the natural wind intensity. The specific settings are as follows: 1. The housing 10 includes a base 11 and a top cover 12 arranged up and down. A plurality of central shafts 13 are fixedly arranged in a ring between the base 11 and the top cover 12, and an evaporation space is formed by sequentially fixedly connecting the base 11, the central shafts 13 and the top cover 12; 2. Refer to Figure 3, the air intake adjustment assembly 30 includes a rotating sleeve 34 and a main board 31 that are rotatably sleeved up and down on the central shaft 13, and the rotating sleeve 34 and the main board 31 are fixed to each other. The rotating sleeve 34 rotates with the main board 31, and the rotating sleeve 34 and the main board 31 are fixed as a whole. The top cover 12 is provided with an inner ring groove 35 and an outer arc groove 36 from the inside to the outside. One end of the central shaft 13 penetrates through the bottom end of the top cover 12, extends into the inner ring groove 35 and is rotatably connected thereto; A driven rod 37 is radially fixed on the outer surface of the rotating sleeve 34 in the inner ring groove 35, and the driven rod 37 is elastically connected to the inner wall of the inner ring groove 35. Under the condition of no natural wind, the position of the central shaft 13 is relatively maintained by the elastic connection. A plurality of auxiliary boards 32 and the main board 31 form the entire annular structure. The specific elastic connection method may be that arc-shaped elastic members 38 are symmetrically fixed on both sides of the driven rod 37. It can be an arc-shaped spring member, and the other end of the arc-shaped elastic member 38 is fixed to the inner wall of the inner ring groove 35. The elastic force of the arc-shaped elastic member 38 forms a dynamic balance with the wind torque; One end of the driven rod 37 radially passes through the inner ring groove 35 and the outer arc groove 36. An expansion resistance strip 39, a speed regulation resistance strip one 310, and a speed regulation resistance strip two 311 are sequentially fixed inside and outside the outer arc groove 36. There are two expansion resistance strips 39 and they are symmetrically distributed. The speed regulation resistance strip one 310 and the speed regulation resistance strip two 311 respectively occupy the left and right positions of the outer arc groove 36. The driven rod 37 is above the expansion resistance strip 39, the speed regulation resistance strip one 310, and the speed regulation resistance strip two 311 and has gaps with them respectively. Expansion conductive rods 312, speed regulation conductive rods one 313, and speed regulation conductive rods two 314 are respectively fixed at the corresponding positions of the expansion resistance strip 39, the speed regulation resistance strip one 310, and the speed regulation resistance strip two 311 in the circumferential direction of the driven rod 37. Among them, the lower end of the expansion conductive rod 312 can contact any one of the expansion resistance strips 39 or be separated from the two expansion resistance strips 39. The speed regulation conductive rod one 313 can contact or be separated from the speed regulation conductive rod one 313. The speed regulation conductive rod two 314 can contact or be separated from the speed regulation resistance strip two 311; On both sides of the main board 31, there are secondary boards 32 with symmetric electromagnetic telescoping. The specific electromagnetic telescoping connection method here is as follows: Telescoping slots are symmetrically opened on both sides of the main board 31. The secondary boards 32 are connected in a limited sliding manner within the telescoping slots. The cross-section of the secondary board 32 is a T-shaped structure. The telescoping slots are used to limit the head of the secondary board 32 to prevent it from slipping out. An air inlet elastic member 33 is fixed between the secondary board 32 and the inner wall of the telescoping slot, which can be a spring member. On the opposite side of the inner wall of the telescoping slot of the secondary board 32, there is an electromagnetic adsorption pair 315. The electromagnetic adsorption pair 315 consists of two magnetically attracted electromagnetic devices. Similarly, the electromagnetic repulsion pair 561 consists of two magnetically repelled electromagnetic devices. The telescoping resistance strip 39 and the telescoping conductive rod 312 are electrically connected to the electromagnetic adsorption pair 315 through a power supply device. By sensing the natural wind intensity, the resistance value in the circuit is adaptively adjusted to pass a suitable current through the electromagnetic adsorption pair 315 and generate a suitable electromagnetic adsorption force. The air inlet elastic member 33 is also shortened or elongated passively, causing the secondary board 32 to generate a suitable telescopic amount relative to the main board 31, so that the natural wind intensity is adapted to the air intake volume; Referring to Figures 1 to 2 , in order to prevent the main board 31 and the secondary board 32 from being affected by the natural wind in the non-working state, an electric anti-rotation ring 316 for limiting the electromagnetic adsorption pair 315 is installed at the lower end of the top cover 12. And 316 is located outside 31 and 32 and restricts their rotation. The electric anti-rotation ring 316 is in an extended state when the energy-saving air heat pump is in an abnormal working state, and the electric anti-rotation ring 316 is limited to prevent the main board 31 from rotating with the rotating sleeve 34; 3. Referring to Figure 2 With Figure 4 , there are two fan assemblies 40, which are fixedly arranged at the air outlet end of the top cover 12. The speed regulation resistance strip one 310 and the speed regulation conductive rod one 313, and the speed regulation resistance strip two 311 and the speed regulation conductive rod two 314 are respectively electrically connected to the two fan assemblies 40 through a power supply device. By setting two fan assemblies 40, during the rotation of the rotating sleeve 34 in any direction, one fan assembly 40 is in a working state. And when the natural wind intensity is relatively small, both fan assemblies 40 work at a relatively high working power.

[0023] It should be noted in advance that Figure 4 The position of the driven rod 37 shown in Once the intensity of the natural wind increases, the natural wind pushes two adjacent auxiliary plates 32 to flip in a certain direction, driving the rotation sleeve 34 to rotate. The rotation directions of the two auxiliary plates 32 are opposite. On the one hand, the driven rod 37 drives the telescopic conductive rod 312 to contact one of the telescopic resistance strips 39, thereby connecting the circuit where the telescopic resistance strip 39 and the electromagnetic adsorption pair 315 are located. It should be noted that the resistance value is the smallest when the telescopic conductive rod 312 just contacts the telescopic resistance strip 39, and the resistance value formed by the telescopic conductive rod 312 and the telescopic resistance strip 39 gradually increases during the process of the telescopic conductive rod 312 gradually moving away from the initial position. When the wind force is relatively small, the magnetic suction force generated by the electromagnetic adsorption pair 315 is relatively large, causing the auxiliary plate 32 to retract to widen the width of the air inlet. When the wind force intensity increases, the telescopic conductive rod 312 rotates at a larger angle, and the magnetic suction force generated by the electromagnetic adsorption pair 315 relatively decreases, causing the auxiliary plate 32 to partially extend to shorten the width of the air inlet, making the natural wind intensity inversely related to the size of the air inlet to relatively maintain an appropriate air intake volume, avoiding too large an air volume resulting in too short an air retention time, and ensuring the heat exchange efficiency of the evaporator assembly 20. On the other hand, when the natural wind intensity is relatively small, although there is a certain angle of rotation, the speed regulation conductive rod one 313 and the speed regulation conductive rod two 314 respectively maintain contact with the speed regulation resistance strip one 310 and the speed regulation resistance strip two 311, and the two fan assemblies 40 are still in a working state with relatively high power. When the natural wind intensity increases, only the speed regulation conductive rod two 314 maintains contact with the speed regulation resistance strip two 311 or the speed regulation conductive rod one 313 maintains contact with the speed regulation resistance strip one 310. During the process of the speed regulation conductive rod one 313 and the speed regulation conductive rod two 314 moving away from the initial position of the driven rod 37, the resistance of the circuits where the speed regulation conductive rod one 313 and the speed regulation resistance strip one 310, and the speed regulation conductive rod two 314 and the speed regulation resistance strip two 311 are located gradually decreases, so as to gradually reduce the power of one of the fan assemblies 40 under the condition of the natural wind with gradually increasing intensity, further maintaining the air volume introduced into the evaporation space per unit time. The natural wind finally flows out from the air outlet end of the top cover 12. During this process, the two arc-shaped elastic members 38 are respectively in a compressed state and an extended state to hold against the natural wind and maintain a dynamic balance.

[0024] In the prior art, the evaporator assembly 20 includes two headers 22 arranged up and down, and heat exchange tubes 21 are connected between the two headers 22. The compressor, condenser, and expansion valve used in cooperation with it are shown in the figure.

[0025] In the process of using the energy-saving air heat pump, the heat exchange efficiency of the evaporator assembly 20 also depends on the cleanliness of the heat exchange tube 21. In the process of introducing natural wind into the shell 10, dust in the natural wind will inevitably adhere to the outer surface of the heat exchange tube 21, and will form a heat insulation layer in a long period of time, affecting the normal heat exchange. In order to solve this problem, the energy-saving air heat pump also includes a cleaning assembly 50, specifically: 1. Reference Figure 6 The cleaning assembly 50 includes a cleaning ring 51 magnetically disposed at the lower end of the manifold 22, and a passive ring 53 is rotatably connected to the outside of the cleaning ring 51. Similarly, the passive ring 53 is also magnetically disposed at the lower end of the manifold 22. In the absence of external force, the cleaning ring 51 and the bristles 52 are in a stable position due to the magnetic attraction, and the conventional setting method of the prior art can be referred to; 2. Brushes 52 are evenly distributed on the inner wall of the cleaning ring 51. The cleaning ring 51 is selectively driven to rise and fall to use the brushes 52 to clean the outer surface of the heat exchange tube 21. The specific selective settings are as follows: Reference Figure 2 The cleaning component 50 also includes a piezoelectric ceramic piece 58 fixed on the fan component 40. The piezoelectric ceramic piece 58 is electrically connected to a resistive dust sensor 57 through a capacitor component, and the resistive dust sensor 57 is fixed on the windward surface of the heat exchange tube 21. When the fan component 40 is in operation, the piezoelectric ceramic piece 58 is vibrated due to operation, and the mechanical energy of the vibration of the fan component 40 is converted into electrical energy and stored in the capacitor component. The capacitor component has a built-in charging control circuit and a threshold detection circuit. When the voltage of the capacitor component reaches the set charging threshold, the discharge process is automatically triggered to provide a stable power supply for the resistive dust sensor 57. The resistive dust sensor 57 intermittently detects the resistance value on the surface of the heat exchange tube 21 and sends it to the control component in real time. The control component compares the received resistance value with the preset resistance value. When the actual detected resistance value is greater than or equal to the preset resistance value, the corresponding cleaning ring 51 can be selectively driven; Reference Figure 6 A lifting ring 54 is coaxially arranged in the housing 10, and the lifting ring 54 is engaged with any cleaning ring 51. The engagement here is specifically as follows: a card slot is provided on the outer side of each passive ring 53, and a slide groove is provided on the inner side of the lifting ring 54 at a position corresponding to the card slot. A card connection structure 56 is arranged in the slide groove, and the card connection structure 56 is used to engage or separate with the passive ring 53; More specifically, see Figure 7, the snap connection structure 56 includes a snap locking rod 563 slidably connected to the chute. A snap elastic member 562 is fixed between the snap locking rod 563 and the inner wall of the chute. An electromagnetic repulsion pair 561 is fixedly arranged between the snap locking rod 563 and the inner wall of the chute. The electromagnetic repulsion pair 561 is similarly composed of two electromagnetic devices arranged by magnetic repulsion. When the control component determines that the actual detected resistance value is greater than or equal to the preset resistance value, the control component controls the electromagnetic repulsion pair 561 to be energized to drive the snap locking rod 563 to be inserted into the slot. During the process of driving the lifting ring 54 to lift and lower, the engagement between the lifting ring 54 and the passive ring 53 drives the passive ring 53 and the cleaning ring 51 to descend.

[0026] The lifting ring 54 is connected to a screw driving mechanism of the prior art. The screw driving mechanism includes a motor fixed to the housing and a screw threadedly connected to the lifting ring. The entire lifting ring 54 is driven to lift and lower through the screw driving mechanism.

[0027] 3. Refer to Figure 6 , a pneumatic blade 55 is fixedly connected to the lower end of the cleaning ring 51. Since the capacitor component reaches the charging threshold, the fan assembly 40 is in the working state. During the process of driving the lifting ring 54, the pneumatic blade 55 drives the cleaning ring 51 to rotate under the action of wind force, so that the cleaning ring 51 rotates while lifting and lowering to clean the outer surface of the entire heat exchange tube 21.

[0028] Among them, the electromagnetic repulsion pair 561, the resistive dust sensor 57, the power supply device, the evaporator assembly 20, and the screw driving mechanism are commonly electrically connected to a control component, and the control component can be a PLC controller.

Therefore, the appended claims are intended to be construed as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
