Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, specifically to an air conditioning device for a containerized mobile cabin used in extreme polar environments. Background Technology

[0002] During the polar night season, temperatures can drop to as low as -40 degrees Celsius, while during the polar day season, temperatures can range from -15 degrees Celsius to 0 degrees Celsius. Mobile living modules are modular living units designed to cope with extreme environments. They are typically constructed with robust, insulated, windproof, and snowproof materials and are transported by sleds or specialized vehicles, facilitating relocation and deployment on ice sheets. The living modules are equipped with basic living facilities such as sleeping areas, kitchens, toilets, and research work areas. They also include power supply (solar or fuel generators), air conditioning, and communication equipment to ensure that expedition members can maintain normal living and working conditions. The air compressor in the air conditioning system may fail to start in extremely low temperatures. This is because the increased viscosity of the compressor's lubricating oil leads to poor lubrication, insufficient motor starting torque, decreased battery performance (for electric drive equipment), condensation blockage in pipes and cylinders, and hardening of sealing materials causing leaks. Furthermore, low temperatures may trigger malfunctions in protective devices, preventing equipment operation.

[0003] In addition, the air inside the containerized mobile cabin is often quite polluted, mainly due to increased carbon dioxide concentration, increased humidity, and possible odors and dust accumulation. Therefore, air conditioning devices are needed to regulate the air quality inside the cabin and heat the fresh air drawn in from the outside to keep the temperature inside the cabin constant.

[0004] When an air conditioning unit operates for extended periods of time, the surface temperature of the evaporator (which acts as a condenser during heating) drops below freezing in low-temperature environments, causing water vapor in the air to condense and gradually freeze. Furthermore, in polar summers, outdoor temperatures are typically around zero degrees Celsius. When air humidity is high and the temperature is close to or below 0°C, the surface of the heat exchanger will continuously absorb heat, causing it to drop below freezing. Adhering water droplets will frost over and accumulate into an ice layer, affecting the heat exchange efficiency of the outdoor unit. Addressing air conditioning noise and vibration issues in mobile living cabins requires various noise reduction measures. These include using sound-insulating materials (such as aluminum foam or damping layers) to encase the air conditioning components in the cabin structure, and also, importantly, blocking the vibration and noise sources from the outdoor unit. Since mobile living cabins are enclosed environments, the air inside can become stale, while the temperature difference with the outside air is significant. Therefore, when introducing fresh outside air into the mobile living cabin, the air conditioning unit needs to heat the outside air. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The present invention will now be described in detail with reference to the accompanying drawings. An air conditioning device for a polar containerized mobile cabin according to the present invention includes a mobile cabin 100 and an air conditioning device 10 disposed on the mobile cabin 100. The air conditioning device 10 is used to regulate 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 disposed in the housing 1. One end of the condenser 2 is connected to the housing of the compressor 4 via a connecting component 3, and the other end is connected to the side plate 12 of the housing 1 via a fixing member 6. The compressor 4 is mounted on the bottom plate 14 of the housing 1 via vibration damping components 5. Multiple vibration damping components 5 are arranged circumferentially at the bottom of the compressor 4. The condenser 2 includes a heat exchange tube 7 communicating with the compressor 4, and a heat exchange component 8 disposed on the heat exchange tube 7. The heat exchange component 8 includes multiple overlapping heat-conducting plates 80, and the heat exchange tube 7 includes multiple bent sections. The bent sections of the heat exchange tube 7 are in contact with the heat-conducting plates 80 of the heat exchange component 8 via contact bodies 70.

[0044] After the containerized mobile cabin is transported to the polar landmass by ship, the air conditioning unit 10 on the mobile cabin 100 needs to operate in a low-temperature environment for an extended period of time. It is crucial to ensure the heat exchange performance of the condenser 2 in the air conditioning unit 10 under prolonged heating conditions. The impact of external frost formation on 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 significant. The heat exchange tubes 7 in the condenser 2 have multiple curved sections, increasing the length of the heat exchange tubes 7 in a condenser 2 of the same volume. This ensures heat exchange efficiency while reducing the need for excessively dense heat dissipation fins on the exterior of the heat exchange tubes 7, preventing frost and ice formation between the dense heat dissipation fins. Furthermore, the dense heat dissipation fins of the heat exchange component 8 in this invention are replaced by the heat-conducting plates 80 of the heat exchange component 8. The heat exchange tubes 7 and the heat-conducting plates 80 are connected by a contact body 70. This assembly structure allows the heat exchange component 8 to receive vibrations transmitted from the compressor 4 through the connecting component 3, thereby reducing frost formation on the heat-conducting plates 80.

[0045] It also includes a regulating assembly 104 connected to the air conditioning device 10; the regulating assembly 104 is connected to a curved pipe 103; wherein the curved pipe 103 includes an inner pipe 105 and an outer pipe 106; the inner pipe 105 is connected to the air inlet 101, and the outer pipe 106 is connected to the air outlet 102. The air conditioning device 10 performs heat exchange outside the mobile cabin 100, and the regulating assembly 104 discharges air from inside the mobile cabin 100 through the air outlet 102, regulating the temperature of the air drawn in from the air inlet 101 and sending it into the mobile cabin 100. The inner pipe 105 and outer pipe 106 in the curved pipe 103 allow the air drawn in through the inner pipe 105 and the air discharged through the outer pipe 106 to exchange heat through the pipe walls. The curved pipe 103 increases the heat exchange area, thereby reducing the temperature difference of the air that needs to be changed by the regulating assembly 104 and the air conditioning device 10. A throttle valve is installed on the curved pipe 103 to adjust the airflow. The airflow in the inner pipe 105 and the outer pipe 106 is controlled according to the airflow level set on the control panel of the regulating component 104.

[0046] 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 fixedly connected to the two sides of the back plate 11 and the bottom plate 14 respectively, and a partition 13 disposed between the two side plates 12. The condenser 2 and the compressor 4 are disposed on both sides of the partition 13.

[0047] The fixing 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 provided between the fixing seat 51 and the support body 53; the elastic body 52 surrounds the support body 53 in the circumferential direction, so that the vibration damping component 5 buffers the compressor 4 from multiple directions.

[0048] Specifically, such as Figure 4 As shown, four equally spaced ear plates 41 are provided around the bottom of the compressor 4. The support body 53 is assembled and fixed to the ear plates 41 by bolts. Figure 5 After the elastic body 52 is fitted onto the support body 53, it is placed on the fixed seat 51. The support body 53 presses the elastic body 52 downward and supports it on the fixed seat 51. Through the elastic body 52 circumferentially surrounding the support body 53, it can not only provide... Figure 5 The vertical buffering also provides buffering in multiple directions on the horizontal plane, 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 working.

[0049] The upper plate 531 of the support body 53 is disposed above the fixed base 51, and the lower plate 533 of the support body 53 is disposed below the fixed base 51; the upper plate 531 and the lower plate 533 are connected by a central column 532; the space between the upper plate 531 and the upper end of the conical hole 511 of the fixed base 51 is filled by the second protrusion 524 of the elastic body 52; the space between the lower plate 533 and the lower end of the conical hole 511 of the fixed base 51 is filled by the first protrusion 521 of the elastic body 52; the lower conical portion 522 and the upper conical portion 525 on the inner side of the annular elastic body 52 abut against the lower plate 533 and the upper plate 531 respectively; an annular cavity 523 is formed between the lower conical portion 522 and the upper conical portion 525.

[0050] For details, please refer to the appendix. Figure 5 The conical hole 511 of the fixing seat 51 has an inclined cross-section, allowing the conical hole 511 to provide lateral and vertical support for the elastic body 52. ​​The upper and lower parts of the central column 532 each have inclined conical surfaces. Figure 5 As shown, the lower conical portion 522 and the upper conical portion 525 of the elastic body 52 can convert the vertical force of the compressor 4 borne by the central column 532 into a horizontal force. The second protrusion 524 of the elastic body 52 can provide elastic support for the upper end face of the upper plate 531 and the fixed seat 51. The first protrusion 521 of the elastic body 52 can provide elastic support for the lower plate 533 and the lower end face of the fixed seat 51. The hollow annular cavity 523 can further improve the buffering effect of the elastic body 52. ​​The central column 532 is a split structure, which is assembled and fixed by bolts in the middle.

[0051] The first side plate 23 of the condenser 2 is connected to the compressor 4 via the connecting assembly 3; the second side plate 24 of the condenser 2 is connected to the side plate 12 of the housing 1 via the 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 support 21 and the lower support 22; the two ends of the heat exchange assembly 8 are connected to the upper support 21 and the lower support 22; the heat exchange tube 7 is installed on the heat exchange assembly 8.

[0052] Unlike existing technologies where the heat exchange tube and heat dissipation fins are integrally formed, in this invention, the heat exchange tube 7 is assembled and connected to the heat-conducting plate 80 of the heat exchange assembly 8. The heat exchange tube 7 is connected to the compressor 4. In order to ensure the sealing of the pipeline, it is necessary to avoid the vibration of the heat exchange tube 7. However, a certain degree of vibration of the heat-conducting plate 80 helps to prevent ice and frost from forming on the surface of the heat-conducting plate 80. The vibration of the compressor 4 during operation can be transmitted to the heat-conducting plate 80 of the heat exchange assembly 8 through the connecting assembly 3. The assembly and connection of the heat exchange tube 7 and the heat-conducting plate 80 can prevent excessive vibration of the heat exchange tube 7 from affecting the seal.

[0053] 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 disposed in the guide sleeve 32, and the pin 311 at the end of the connecting rod 31 is slidably disposed in the waist hole 321 of the guide sleeve 32; a card 33 is fixed on the pin 311 by bolts to lock the connecting rod 31 and the guide sleeve 32.

[0054] During the installation of condenser 2, the compressor 4 and condenser 2 are tightly connected via connecting assembly 3. This is achieved by changing the depth to which connecting rod 31 is inserted into guide sleeve 32, such as... Figure 7 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.

[0055] 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 disposed on the second side plate 24 of the condenser 2; the support plate 61 is provided with a slot 611, and the T-shaped ear plate 631 of the hanging plate 63 is inserted into the receiving part 621 of the rubber body 62; the rubber body 62 and the hanging plate 63 are disposed in the slot 611.

[0056] The installation method of the condenser 2 and compressor 4 of the present invention realizes a rigid connection between the condenser 2 and compressor 4, and an elastic connection between compressor 4 and housing 1 through vibration damping component 5, and an elastic connection between condenser 2 and housing 1 through fastener 6. This can prevent the vibration of compressor 4 from being transmitted to housing 1, reduce the vibration and noise generated by air conditioning device 10 on mobile compartment 100, and at the same time enable condenser 2 to reduce icing on the surface of heat conduction plate 80 in condenser 2 by means of the vibration of compressor 4.

[0057] The heat exchange assembly 8 includes multiple heat-conducting plates 80 that are fixed together end to end; the protrusions 82 at both ends of the heat-conducting plates 80 are respectively inserted into the fixing slots 20 of the upper bracket 21 and the lower bracket 22; multiple fins 83 are provided on the heat-conducting plate 84 of the heat-conducting plate 80, and the heat-conducting plate 84 and the fins 83 have different extension directions; a slot 81 is formed between the fins 83, and the heat exchange tube 7 is fixed in the slot 81; multiple grooves 85 are provided at the end of the heat-conducting plate 84 away from the fins 83; the fins 83 of the heat-conducting plate 80 are fixed together in the grooves 85 of the adjacent heat-conducting plates 80.

[0058] like Figure 9 Specifically, the heat-conducting plate 80 has an L-shaped bent structure, and the extension direction of the fins 83 and the heat-conducting plate 84 is approximately perpendicular. The heat-conducting plate 80 is connected end to end, i.e. Figure 9 The rightmost heat-conducting plate 80 has fins 83 facing upwards, while the adjacent heat-conducting plate 80 has fins 83 facing downwards. The rightmost heat-conducting plate 80's fins 83 overlap and are fixed in the groove 85 at the end of the heat-conducting plate 84 of the adjacent heat-conducting plate 80. The heat-conducting plates 80 are alternately overlapped to form a heat exchange assembly 8.

[0059] The heat exchange tube 7 includes a first bend 71 facing a first direction and a second bend 72 facing a second direction; the first direction is opposite to the second direction, and multiple first bends 71 ​​and second bends 72 are alternately connected to form a heat exchange tube unit; the heat exchange tube units are connected by a connecting section 73.

[0060] By providing multiple first bends 71 ​​and second bends 72 on the heat exchange tube 7, a longer path of heat exchange tube 7 can be provided in the condenser 2 of the same volume, thereby improving the heat exchange efficiency of the refrigerant fluid in the heat exchange tube 7. Specifically, as shown... Figure 10 The first bent portion 71 bends upward and connects to the slot 81 at the upper end of the rightmost heat-conducting plate 80. The second bent portion 72 bends downward and connects to the slot 81 at the lower end of its corresponding heat-conducting plate 80. The heat-conducting plates 80 corresponding to the first bent portion 71 and the second bent portion 72 have opposite orientations.

[0061] Contact bodies 70 are respectively provided on the first curved portion 71 and the second curved portion 72; the arc-shaped segment 701 of the contact body 70 abuts against the first and second curved portions; the U-shaped body 702 of the contact body 70 engages with the slot 81 of the heat-conducting sheet 80.

[0062] Specifically, the arc-shaped segment 701 of the contact body 70 has an outer shape consistent with the outer wall shape of the first curved portion 71 and the second curved portion 72. Specifically, the first curved portion 71 and the second curved portion 72 are arc-shaped curved portions, and the curvature of the arc-shaped segment 701 is the same as that of the first curved portion 71 and the second curved portion 72. When the lateral position of the heat-conducting plate 80 of the condenser 2 and the heat exchange assembly 8 is changed by the connecting assembly 3, the heat-conducting plate 80 drives the contact body 70 to slide a certain distance along the arc-shaped segment of the first curved portion 71 and the second curved portion 72. The first curved portion 71 and the second curved portion 72 can push the contact body 70 towards the slot 81 of the heat-conducting plate 80, so that a tight connection is formed between the heat exchange tube 7, the contact body 70, and the heat-conducting plate 80. The hardness of the material of the arc-shaped segment 701 of the contact body 70 is less than that of the heat exchange tube 7, and wear occurs on the arc-shaped segment 701 of the contact body 70 after long-term operation.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
