Description

Technical Field

[0001] The present invention relates to the technical field of air energy, and particularly to an integrated modular air energy system. Background Art

[0002] Air energy refers to the low-grade thermal energy contained in the air. Heat cannot be transferred from a low-temperature object to a high-temperature object without causing other changes. Although air energy is inexhaustible, if the energy absorbed from the air needs to be transferred to a high-temperature environment, electrical energy or thermal energy needs to be consumed, which is generally achieved through an air source heat pump unit.

[0003] When the existing air energy systems are applied, each system is relatively independent and cannot cooperate with each other. The independent operation of each system is prone to shutdown and repair due to external frosting, which will affect the use effect of the equipment. Moreover, the separate installation of each system has limitations and inconveniences for the installation of system pipelines and water pipelines. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of poor use effect of the existing units, and an integrated modular air energy system is proposed.

[0005] To achieve the above purpose, the present invention adopts the following technical solution: an integrated modular air energy system, including a container. The inside of the container is connected with a host through a shock absorption protection mechanism. There are multiple groups of the hosts. A plurality of fin heat exchangers are installed on the top of the container. The fin heat exchangers are matched and combined with the hosts. A water pump and a buffer water tank are installed inside the container. A support bottom frame is fixed at the bottom of the container. A transfer and stabilization mechanism is provided inside the support bottom frame. Sound insulation cotton is installed on the inner wall of the container. An internal water jacket is fixed on the side wall of the sound insulation cotton. A protection airbag is installed on the inner top of the container.

[0006] In the above integrated modular air energy system, the shock absorption protection mechanism includes a mounting frame fixed on the side wall of the internal water jacket. A support seat is connected to the side wall of the mounting frame through a swing spring. A floating spring is jointly fixed between the lower part of the support seat and the internal water jacket. The host is installed on the upper end of the mounting frame.

[0007] In the above integrated modular air energy system, the mounting frame is of an annular frame structure. A plurality of piezoelectric blocks are fixed on the inner wall of the mounting frame. The piezoelectric blocks are made of piezoelectric ceramics.

[0008] In the above integrated modular air energy system, a pumping box is fixed on the side wall of the internal water jacket. The pumping box is located directly below the support seat. Transfer pipes are inserted through both ends of the pumping box. The transfer pipes are connected to the protection airbag. An air extraction pipe is inserted through the bottom of the pumping box. A water extraction pipe connected to the internal water jacket is inserted through the bottom of the transfer pipe.

[0009] In the above integrated modular air energy system, a pumping plate is sealingly and slidably connected to the inner wall of the pumping box. A reset spring is jointly fixed between the pumping plate and the side wall of the pumping box. The interior of the pumping box is filled with electrorheological fluid.

[0010] In the above integrated modular air energy system, electromagnetic valves and check valves are installed at the ends of the air extraction pipe, the transfer pipe, and the water extraction pipe. The check valves inside the two water extraction pipes lead in opposite directions.

[0011] In the above integrated modular air energy system, the transfer and stabilization mechanism includes a driving motor fixed to the bottom of the container. A driving worm is fixed to the output shaft of the driving motor. A driving rotating shaft is rotatably connected to the side wall of the supporting bottom frame. A driving worm gear and rollers are fixed to the side wall of the driving rotating shaft. The driving worm gear meshes with the driving worm. A plurality of ground digging teeth are fixed to the side wall of the roller.

[0012] Compared with the existing technology, the advantages of the present invention are as follows:

[0013] 1. In the present invention, in the form of a container, the compressor, the water heat exchanger, the fluorine system valve components, the water pump and the buffer water tank in the water circuit system, etc. are placed inside the container, and the fin heat exchanger is placed on the top. With an integrated design, it avoids the installation problems of the main unit and part of the water circuit on site. By separating the fin heat exchanger from the main body of the main unit, it realizes the integration of the machine room and solves the heat preservation problem of the main unit part.

[0014] 2. In the present invention, different units are set, and sound-absorbing cotton is arranged inside at the same time. The noise of the main compressors of the units is isolated indoors, which is convenient for installation around the community. Multiple units can cooperate with each other. Under partial load, the alternate shutdown defrosting technology is used, which does not affect the indoor heating effect.

[0015] 3. In the present invention, through integrated collaborative control, it effectively deals with the frosting and defrosting problems of the units under partial load. Using the waste heat after the water heat exchanger for defrosting can achieve subcooling of the refrigerant, absorb more defrosting heat from the air, and improve the overall energy efficiency of the units.

[0016] 4. In the present invention, the protective airbag can expand and extend downward, so as to wrap and protect the main unit from top to bottom, and is positively correlated with the actual degree of transportation shaking, and can more effectively protect the main unit from being damaged by collision during transportation.

[0017] 5. In the present invention, the swing spring and the floating spring can absorb the vibration energy generated during the operation of the main unit, and then reduce the vibration energy from being transmitted externally in the form of vibration noise, thereby avoiding the influence of the internal operation on the external environment.

[0018] 6. In the present invention, the rollers can be embedded into the ground until the supporting bottom frame is effectively clamped into the ground, realizing the effective fixation and installation of the container itself, making the installation of the container simple and effective. At the same time, the existence of the ground-engaging teeth can improve the transfer ability during equipment transfer and can effectively handle various road sections.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention. Embodiment

[0026] Refer to Figures 1-5, an integrated modular air energy system, including a container 1. Inside the container 1, a host 2 is connected through a shock protection mechanism. The host 2 includes a compressor, a water heat exchanger, and fluorine system valve components. There are multiple groups of the host 2. On the top of the container 1, multiple finned heat exchangers 3 are installed. The finned heat exchangers 3 are matched and combined with the host 2. Inside the container 1, a water pump 4 and a buffer water tank 5 are installed. At the bottom of the container 1, a support bottom frame 9 is fixed. Inside the support bottom frame 9, a transfer and stabilization mechanism is provided. On the inner wall of the container 1, a sound insulation cotton 6 is installed. On the side wall of the sound insulation cotton 6, an internal water jacket 7 is fixed. On the inner top of the container, a protection airbag 8 is installed. Both the internal water jacket 7 and the sound insulation cotton 6 can achieve effective sound insulation effects, so that the equipment can be installed near residential areas, facilitating use and installation. At the same time, due to the large specific heat capacity of the internal water jacket 7 itself, an internal constant temperature state can be achieved.

[0027] The shock protection mechanism includes a mounting frame 16 fixed to the side wall of the internal water jacket 7. The side wall of the mounting frame 16 is connected to a support seat 18 through a swing spring 17. At the lower part of the support seat 18 and the internal water jacket 7, a floating spring 19 is jointly fixed. The host 2 is installed at the upper end of the mounting frame 16. By using the swing spring 17 and the floating spring 19, the consumption of the movement energy of the host 2 is realized, reducing its vibration damage and the spillage of vibration energy.

[0028] The mounting frame 16 is of an annular frame structure. On the inner wall of the mounting frame 16, multiple piezoelectric blocks 20 are fixed. The piezoelectric blocks 20 are made of piezoelectric ceramics. When the piezoelectric ceramics are pressed, instant high-voltage electricity will be generated. On the side wall of the internal water jacket 7, a pumping box 21 is fixed. The pumping box 21 is located directly below the support seat 18. At both ends of the pumping box 21, transfer pipes 24 are inserted through. The transfer pipes 24 are connected to the protection airbag 8. At the bottom of the pumping box 21, an air extraction pipe 25 is inserted through. At the bottom of the transfer pipe 24, a water extraction pipe 26 connected to the internal water jacket 7 is inserted through.

[0029] The inner wall of the pumping box 21 is hermetically and slidably connected with a pumping plate 23. The pumping plate 23 and the side wall of the pumping box 21 jointly fix a return spring 22. The inside of the pumping box 21 is filled with an electrorheological fluid. The electrorheological fluid will solidify itself and expand significantly after being electrified, and instantly return to its original state after being powered off. Solenoid valves and check valves are installed at the ends of the air extraction pipe 25, the transfer pipes 24, and the water extraction pipes 26. The check valves inside the two water extraction pipes 26 lead in opposite directions. By using the electricity of the piezoelectric blocks 20 to drive the morphological transformation of the electrorheological fluid, the piston movement of the pumping plate 23 is realized. When needed, pump the expanded gas to the protection airbag 8, thereby forming a wrapped protection for the host 2 to avoid collision damage during transportation. When the unit is operating, pump the water flow inside the internal water jacket 7 to realize the flow of the water flow, and then make the heat distribution inside the container 1 balanced.

[0030] The transfer and stabilization mechanism includes a driving motor 10 fixed to the bottom of the container 1. A driving worm 11 is fixed to the output shaft of the driving motor 10. A driving rotating shaft 12 is rotatably connected to the side wall of the supporting bottom frame 9. A driving worm wheel 13 and a roller 14 are fixed to the side wall of the driving rotating shaft 12. The driving worm wheel 13 meshes with the driving worm 11. A plurality of ground-digging teeth 15 are fixed to the side wall of the roller 14. The ends of the ground-digging teeth 15 are sharp. The whole is like a shovel and can dig the ground during the rotation process, so that it can sink into the ground, effectively restricting the movement of the container 1, and thus enabling the rapid and effective installation of the container 1.

[0031] In the present invention, during actual operation, there are three different modes, namely the heating mode, the cooling mode, and the defrosting mode. Each main unit 2 and the corresponding fin heat exchanger 3 form a set of units.

[0032] In the heating mode, through the coordinated control of the units, different loads in the room are adjusted, and different numbers of units are selected to be turned on. The units work to provide heat sources. Through the operation of the water pump 4 in the modular container 1, the heating hot water is supplied to the end.

[0033] In the cooling mode, through the coordinated control of the units, different loads in the room are adjusted, and different numbers of units are selected to be turned on. The units work to provide cold sources. Through the operation of the water pump in the modular container, the cooling cold water is supplied to the end.

[0034] In the defrosting mode, in the partial load state, when it is detected that the fins of the unit are frosted, when one unit stops working, the adjacent unit starts to operate for alternating defrosting.

[0035] The operation of the actual system is as follows.

[0036] In the cooling mode, solenoid valve ① is opened and solenoid valve ② is closed for normal cooling control.

[0037] Heating mode: Solenoid valve ① is opened and solenoid valve ② is closed for normal heating control.

[0038] Defrosting mode: In the partial load condition, when the B system is turned on and reaches the defrosting point, the B system stops operating, solenoid valve ① is closed, solenoid valve ② is opened, and the A system is turned on. At this time, the A system heats up and defrosts the B system simultaneously. Through the integrated coordinated control, the problem of frosting and defrosting of the unit under partial load can be effectively solved. Using the waste heat after the water heat exchanger for defrosting can achieve subcooling of the refrigerant, absorb more defrosting heat from the air, and improve the overall energy efficiency of the unit.

[0039] When the device is transported and transferred, the solenoid valve inside the water suction pipe 26 is closed, while the solenoid valves inside the air suction pipe 25 and the transfer pipe 24 are opened. When the transport vehicle jolts and vibrates, the swing spring 17 and the floating spring 19 can greatly reduce the movement amplitude of the main unit 2, thus avoiding the collision between the main unit 2 and the inner wall of the container 1, effectively protecting the main unit 2 from damage. The swing of the main unit 2 will cause the support seat 18 to swing and hit the piezoelectric block 20, and then the piezoelectric block 20 will be subjected to intermittent collision and extrusion. Since the piezoelectric block 20 is made of piezoelectric ceramics, it can generate instantaneous high voltage electricity at the moment of being collided and extruded, and then transmit it to the electrorheological fluid inside the pumping box 21, so that the electrorheological fluid solidifies instantly after being electrified, and is accompanied by a significant volume expansion, which can then push the pumping plate 23 to move. Since the power transmission is instantaneous, the electrorheological fluid returns to the liquid state instantly and the volume recovers after losing power, so that the pumping plate 23 can make a reciprocating piston movement under the elastic force of the reset spring 22, and then can realize the pumping and transfer of the fluid. In this state, external gas will be extracted through the air suction pipe 25, and then filled into the airbag 8 through the transfer pipe 24, so that the airbag 8 can expand and extend downward, thus wrapping and protecting the main unit 2 from top to bottom, and being positively correlated with the actual transport shaking degree, which can more effectively protect the main unit 2 from being damaged by collision during transportation;

[0040] When the unit is operating normally, the main unit 2 will also vibrate due to operation, which will cause the pumping plate 23 to form a piston movement. In this state, the air suction pipe 25 is closed, and at the same time, the connection end of the transfer pipe 24 and the airbag 8 is closed, and the water suction pipe 26 is open. The piston movement of the pumping plate 23 will cause the water flow on both sides of the built-in water jacket 7 to be transferred and flow through the pumping box 21, so that the water flow inside the built-in water jacket 7 is no longer static, and can accelerate the heat transfer at each position through its own flow. When some units stop, it can maintain the heat balance inside the container 1, and the swing spring 17 and the floating spring 19 can absorb the vibration energy generated during the operation of the main unit 2, and then reduce the vibration energy from being transmitted to the outside in the form of vibration noise, thus avoiding the influence of the internal operation on the external environment;

[0041] During the equipment transfer process, starting the drive motor 10 can drive the drive worm 11 to rotate, which will drive the drive worm wheel 13 to rotate, so that the drive rotating shaft 12 can rotate effectively, enabling the roller 14 to realize the automatic transfer of the equipment through rotation, and then facilitating the movement of the equipment itself to a suitable installation position and reducing the actual conveying difficulty;

[0042] After the installation position is determined, limit devices can be added to both sides of the container 1 to restrict the movement of the container 1. Then, increase the rotational speed of the drive motor 10 so that the drive motor 10 can drive the rollers 14 to perform high-speed rotation. Since the container 1 is restricted and cannot move, the rollers 14 will exhibit a slipping action, and this action will enable the ground-engaging teeth 15 on the side walls of the rollers 14 to cut the ground, thereby sinking into the ground, allowing the rollers 14 to be embedded in the ground until the support bottom frame 9 is effectively stuck into the ground, achieving effective fixation and installation of the container 1 itself, making the installation of the container 1 simple and effective. At the same time, the presence of the ground-engaging teeth 15 can improve the transfer ability of the equipment during transfer and can effectively face various road sections.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
