Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to an air conditioning device for a containerized mobile cabin in polar extreme environments. Background Art

[0002] In the polar regions, the lowest temperature during the polar night season can reach -40°C, and the temperature during the polar day season can reach from -15°C to 0°C. The mobile living cabin is a modular living unit designed to cope with extreme environments. It is usually built with strong materials for heat preservation, wind prevention, and snow prevention, and is towed by sleds or special vehicles, facilitating migration and deployment on the ice sheet. The living cabin is equipped with basic living facilities such as a sleeping area, a kitchen, a bathroom, and a scientific research work area, and is also equipped with power supply (solar energy or fuel generator), an air conditioning device, and communication equipment to ensure that the expedition members can maintain normal life and work under harsh conditions. The air compressor of the air conditioning device may not be able to start in extremely low temperature environments because the viscosity of the lubricating oil of the compressor increases in low temperature environments, resulting in poor lubrication, insufficient starting torque of the motor, degradation of battery performance (for electric drive equipment), freezing and blockage of condensed water in pipelines and cylinders, and leakage caused by hardening of sealing materials. In addition, low temperature may also trigger misoperation of the protection device, preventing the equipment from running.

[0003] In addition, the turbidity of the air inside the containerized mobile cabin is relatively high, mainly manifested as an increase in carbon dioxide concentration, an increase in humidity, etc., as well as possible peculiar smells and dust accumulation. Therefore, it is necessary to use an air conditioning device to adjust the air quality inside the cabin and heat the fresh air inhaled from the outside to keep the temperature inside the cabin constant.

[0004] When the air conditioning device heats for a long time, the surface temperature of the evaporator (acting as a condenser during heating) is lower than the zero temperature in a low temperature environment, which will cause water vapor in the air to condense and gradually freeze. And for the outdoor temperature in the polar summer is usually around zero degrees. When the air humidity is high and the air temperature is close to or below 0°C, the surface of the heat exchanger will drop below the freezing point due to continuous heat absorption, and the attached water droplets will frost and accumulate into ice layers, affecting the heat exchange efficiency of the outdoor unit of the air conditioner. To solve the problems of air conditioner noise and vibration in the mobile living cabin, various noise reduction measures need to be taken. The cabin structure can be wrapped with sound insulation materials (such as aluminum foam, damping layer) for air conditioner components. At the same time, it is particularly important to block the vibration and noise sources of the outdoor unit of the air conditioner. The mobile living cabin is a closed environment, and the internal air will become turbid. With a large temperature difference between the outside air, when sending the fresh air from the outside into the inside of the mobile living cabin, it is necessary to use the air conditioning device to heat up the outside air.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be described in detail below with reference to the accompanying drawings. An air conditioning device for a polar container mobile cabin of the present invention includes a mobile cabin 100 and an air conditioning device 10 provided on the mobile cabin 100. The air conditioning device 10 is used to adjust the internal temperature of the mobile cabin 100. The air conditioning device 10 includes a housing 1 connected to the wall of the mobile cabin 100. A condenser 2 and a compressor 4 are provided in the housing 1. One end of the condenser 2 is connected to the housing of the compressor 4 through a connecting component 3, and the other end is connected to the side plate 12 of the housing 1 through a fixing member 6. The compressor 4 is installed on the bottom plate 14 of the housing 1 through a vibration damping component 5. There are multiple vibration damping components 5, and they are circumferentially arranged at the bottom of the compressor 4. The condenser 2 includes a heat exchange tube 7 communicated with the compressor 4 and a heat exchange assembly 8 provided on the heat exchange tube 7. The heat exchange assembly 8 includes a plurality of mutually overlapping heat conducting sheets 80. The heat exchange tube 7 includes a plurality of bending sections. The bending sections of the heat exchange tube 7 are in contact connection with the heat conducting sheets 80 of the heat exchange assembly 8 through a contact body 70.

[0021] After the containerized mobile cabin is transported to the polar land surface by ship, the air conditioning device 10 on the mobile cabin 100 needs to heat for a long time in a low-temperature environment. It is necessary to ensure the heat exchange performance of the condenser 2 in the air conditioning device 10 under long-term heating conditions. Among them, the influence of external frosting of the condenser 2 due to heating in a low-temperature environment on the performance of the heat exchange component 8 of the condenser 2 is particularly prominent. The heat exchange tube 7 in the condenser 2 has multiple bending sections, which increases the arrangement length of the heat exchange tube 7 in the condenser 2 of the same volume. While ensuring the heat exchange efficiency, the setting of overly dense heat dissipation fins outside the heat exchange tube 7 is reduced to avoid frosting and icing between the dense heat dissipation fins. At the same time, the heat conduction fins 80 of the heat exchange component 8 in the present invention replace the dense heat dissipation fins in the prior art. At the same time, the heat exchange tube 7 and the heat conduction fins 80 are assembled and connected through the contact body 70. Through the assembly structure, the heat exchange component 8 receives the vibration transmitted by the compressor 4 through the connection component 3, and uses this vibration to reduce the frosting of the heat conduction fins 80.

[0022] It further includes an adjustment component 104 connected to the air conditioning device 10; a curved tube 103 is connected to the adjustment component 104; wherein the curved tube 103 includes an inner tube 105 and an outer tube 106; the inner tube 105 is connected to the air inlet 101, and the outer tube 106 is connected to the air outlet 102. Among them, the air conditioning device 10 performs heat exchange outside the mobile cabin 100. The adjustment component 104 discharges the air inside the mobile cabin 100 from the air outlet 102, adjusts the temperature of the air inhaled from the air inlet 101 and sends it into the mobile cabin 100. Among them, the inner tube 105 and the outer tube 106 in the curved tube 103 enable the air inhaled in the inner tube 105 to exchange heat with the air discharged in the outer tube 106 through the tube wall. The curved tube 103 increases the heat exchange area pipeline interval, thereby reducing the temperature difference of the air that needs to be changed by the action of the adjustment component 104 and the air conditioning device 10. A throttle valve for adjusting the air flow is provided on the curved tube 103, and the air flow in the inner tube 105 and the outer tube 106 is controlled according to the air volume gear set on the control panel of the adjustment component 104.

[0023] The housing 1 includes a back plate 11 and a bottom plate 14 fixed to the side wall of the mobile cabin 100, side plates 12 respectively fixedly connected to both sides of the back plate 11 and the bottom plate 14, and a partition plate 13 disposed between the two side plates 12. The condenser 2 and the compressor 4 are disposed on both sides of the partition plate 13.

[0024] The fixed seat 51 of the vibration damping component 5 is fixed to the bottom plate 14 of the housing 1, and the support body 53 of the vibration damping component 5 is fixed to the ear plate 41 at the bottom of the compressor 4; an elastic body 52 is disposed between the fixed seat 51 and the support body 53; the elastic body 52 circumferentially surrounds the support body 53, so that the vibration damping component 5 buffers the compressor 4 from multiple directions.

[0025] Specifically, as Figure 4 shown, four equally spaced ear plates 41 are provided around the bottom of the compressor 4, and the support body 53 is assembled and fixed to the ear plates 41 by bolts. According to the appendix Figure 5 , after the elastomer 52 is sleeved on the support body 53, it is placed on the fixing base 51. The support body 53 presses down on the elastomer 52 and supports it on the fixing base 51. Through the elastomer 52 circumferentially surrounding the support body 53, not only can it provide buffering in the vertical direction as Figure 5 in the figure, but also buffering in multiple directions on the horizontal plane can be achieved, preventing the vibration of the compressor 4 from being transmitted to the bottom plate 14 of the housing 1 and reducing the vibration and noise generated on the side wall of the mobile cabin 100 when the air conditioning device 10 is operating.

[0026] The upper disc 531 of the support body 53 is arranged above the fixing base 51, and the lower disc 533 of the support body 53 is arranged below the fixing base 51; the upper disc 531 and the lower disc 533 are connected by a central column 532; the space between the upper disc 531 and the upper end of the tapered hole 511 of the fixing base 51 is filled by the second protruding portion 524 of the elastomer 52; the space between the lower disc 533 and the lower end of the tapered hole 511 of the fixing base 51 is filled by the first protruding portion 521 of the elastomer 52; the lower tapered portion 522 and the upper tapered portion 525 on the inner side of the annular elastomer 52 respectively abut against the lower disc 533 and the upper disc 531; an annular cavity 523 is formed between the lower tapered portion 522 and the upper tapered portion 525.

[0027] Specifically, referring to the appendix Figure 5 , the cross-section of the tapered hole 511 of the fixing base 51 is inclined, so that the tapered hole 511 can support the elastomer 52 both horizontally and vertically. The upper and lower parts of the central column 532 respectively have inclined tapered surfaces, as shown in the appendix Figure 5 , which are respectively connected to the lower tapered portion 522 and the upper tapered portion 525 of the elastomer 52, and can convert the vertical force of the central column 532 bearing the compressor 4 into a horizontal force. The second protruding portion 524 of the elastomer 52 can elastically support the upper disc 531 and the upper end face of the fixing base 51, and the first protruding portion 521 of the elastomer 52 can elastically support the lower disc 533 and the lower end face of the fixing base 51. The hollow annular cavity 523 can further improve the buffering effect of the elastomer 52. The central column 532 is a split structure up and down and is assembled and fixed by bolts in the middle.

[0028] The first side plate 23 of the condenser 2 is connected to the compressor 4 through a connection assembly 3; the second side plate 24 of the condenser 2 is connected to the side plate 12 of the housing 1 through a fixing member 6; the upper and lower ends of the first side plate 23 and the second side plate 24 are respectively fixed to the upper bracket 21 and the lower bracket 22; both ends of the heat exchange assembly 8 are connected to the upper bracket 21 and the lower bracket 22; the heat exchange tube 7 is installed on the heat exchange assembly 8.

[0029] Different from the integrally formed heat exchange tube and heat dissipation fins in the prior art, the heat exchange tube 7 of the present invention is assembled and connected to the heat conduction fin 80 of the heat exchange assembly 8. The heat exchange tube 7 is communicated with the compressor 4. To ensure the sealing of the pipeline, the vibration of the heat exchange tube 7 needs to be avoided. However, a certain degree of vibration of the heat conduction fin 80 helps to avoid icing and frosting on the surface of the heat conduction fin 80. The vibration during the operation of the compressor 4 can be transmitted to the heat conduction fin 80 of the heat exchange assembly 8 through the connection assembly 3. The assembled connection between the heat exchange tube 7 and the heat conduction fin 80 can prevent excessive vibration of the heat exchange tube 7 from affecting the sealing.

[0030] The connecting rod 31 of the connecting assembly 3 is fixedly connected to the first side plate 23 of the condenser 2; the guide sleeve 32 of the connecting assembly 3 is fixedly connected to the housing of the compressor 4; the connecting rod 31 is arranged in the guide sleeve 32, and the pin 311 at the end of the connecting rod 31 is slidably arranged in the kidney-shaped hole 321 of the guide sleeve 32; a card 33 is fixed to the pin 311 by a bolt to realize the locking of the connecting rod 31 and the guide sleeve 32.

[0031] When installing the condenser 2, the compressor 4 and the condenser 2 are tightly connected through the connection assembly 3. By changing the depth of the connecting rod 31 inserted into the guide sleeve 32, such as Figure 7 ., and then the connecting rod 31 and the guide sleeve 32 are locked by the card 33 and the bolt to adjust the distance between the condenser 2 and the compressor 4.

[0032] The support plate 61 of the fixing member 6 is fixed to the side plate 12 of the housing 1, and the hanging plate 63 of the fixing member 6 is arranged on the second side plate 24 of the condenser 2; a slot 611 is arranged on the support plate 61, and the T-shaped ear plate 631 of the hanging plate 63 is inserted into the accommodating portion 621 of the rubber body 62; the rubber body 62 and the hanging plate 63 are arranged in the slot 611.

[0033] The installation method of the condenser 2 and the compressor 4 of the present invention realizes the rigid connection between the condenser 2 and the compressor 4. The compressor 4 and the housing 1 are elastically connected through the vibration damping assembly 5, and the condenser 2 and the housing 1 are elastically connected through the fixing member 6, which can prevent the vibration of the compressor 4 from being transmitted to the housing 1, reduce the vibration and noise generated by the air conditioning device 10 to the mobile cabin 100, and at the same time enable the condenser 2 to rely on the vibration of the compressor 4 to slow down the icing on the surface of the heat conduction fin 80 in the condenser 2.

[0034] The heat exchange component 8 includes a plurality of heat conducting sheets 80 that are fixed with their heads and tails lapped; the protruding parts 82 at both ends of the heat conducting sheet 80 are respectively inserted into the fixing grooves 20 of the upper bracket 21 and the lower bracket 22; a plurality of fins 83 are arranged on the heat conducting plate 84 of the heat conducting sheet 80, and the heat conducting plate 84 and the fins 83 have different extending directions; a card slot 81 is formed between the fins 83, and the heat exchange tube 7 is fixed in the card slot 81; a plurality of lapping slots 85 are arranged at the end of the heat conducting plate 84 away from the fins 83; the fins 83 of the heat conducting sheet 80 are lapped and fixed in the lapping slots 85 at the end of the heat conducting plate 84 of the adjacent heat conducting sheet 80.

[0035] As Figure 9 , specifically, the heat conducting sheet 80 is an L-shaped bending structure, the extending direction of the fin 83 is approximately perpendicular to that of the heat conducting plate 84, and the heat conducting sheets 80 are connected end to end, that is, as Figure 9 shown in, the fins 83 of the rightmost heat conducting sheet 80 in are arranged upward, the fins 83 of the adjacent heat conducting sheet 80 are arranged downward, the fins 83 of the rightmost heat conducting sheet 80 are lapped and fixed in the lapping slot 85 at the end of the heat conducting plate 84 of the adjacent heat conducting sheet 80, and the heat conducting sheets 80 are alternately lapped to form the heat exchange component 8.

[0036] The heat exchange tube 7 includes a first bending part 71 facing the first direction and a second bending part 72 facing the second direction; the first direction is opposite to the second direction, and a plurality of first bending parts 71 and second bending parts 72 are alternately connected to form a heat exchange tube unit; the heat exchange tube units are connected through a communication section 73.

[0037] By arranging a plurality of first bending parts 71 and second bending parts 72 on the heat exchange tube 7, a heat exchange tube 7 with a longer path can be arranged in the condenser 2 of the same volume, improving the heat exchange efficiency of the refrigerant fluid in the heat exchange tube 7. Specifically, as Figure 10 shown in, the first bending part 71 bends upward and is connected to the card slot 81 at the upper end of the rightmost heat conducting sheet 80, the second bending part 72 bends downward and is connected to the card slot 81 at the lower end of the corresponding heat conducting sheet 80, and the heat conducting sheets 80 corresponding to the first bending part 71 and the second bending part 72 have opposite orientations.

[0038] Contact bodies 70 are respectively arranged on the first bending part 71 and the second bending part 72; the arc section 701 of the contact body 70 abuts against the first and second bending parts; the U-shaped body 702 of the contact body 70 is clamped with the card slot 81 of the heat conducting sheet 80.

[0039] Specifically, the arc segment 701 of the contact body 70 has an outer wall shape that is consistent with the outer wall shapes of the first bending portion 71 and the second bending portion 72. Specifically, the first bending portion 71 and the second bending portion 72 are arc-shaped bending portions, and the radian of the arc segment 701 is the same as the radian of the first bending portion 71 and the second bending portion 72. When changing the lateral position of the condenser 2 and the heat conducting fins 80 of the heat exchange assembly 8 through the connecting assembly 3, the heat conducting fins 80 drive the contact body 70 to slide a certain distance along the arc segments of the first bending portion 71 and the second bending portion 72. The first bending portion 71 and the second bending portion 72 can push the contact body 70 towards the card slot 81 of the heat conducting fin 80, so as to form a tight connection among the heat exchange tube 7, the contact body 70 and the heat conducting fin 80. The hardness of the material of the arc segment 701 of the contact body 70 is less than the hardness of the material of the heat exchange tube 7, and wear is generated on the arc segment 701 of the contact body 70 after long-term operation.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
