Description

Technical Field

[0001] The present invention relates to the technical field of tethered airships, and in particular to a bladder cooling and heating control system and method for tethered airships. Background Art

[0002] Temperature control of tethered airships is a complex and critical system engineering, especially in high-altitude environments such as the stratosphere, where the temperature difference between day and night is extremely large, which will have a significant impact on the internal pressure, performance, stability and safety of the tethered airship. The main methods of airship temperature control include using insulation materials, designing ventilation systems, and utilizing energy storage, etc.: ‌Use of insulation materials‌: In order to cope with the extreme temperature changes at high altitudes, the airship can be wrapped with materials with good insulation properties. However, although this material has good insulation effect, it is usually bulky and may affect the flight performance of the airship.‌

[0003] ‌Design ventilation system‌: The temperature inside the airship can be regulated by designing a clever ventilation system. For example, the air inlet can be placed at the bottom of the airship and the air outlet at the top, so that hot air can be easily discharged, thereby improving the temperature control inside the airship. This method is simple in design, but the temperature control effect is limited.

[0004] Energy storage and release mechanism: Energy is stored when the temperature is appropriate and released at extreme temperatures to regulate temperature. This method requires further research on the specific storage and release mechanisms. Summary of the invention

[0015] In order to make the technical purpose, technical solution and beneficial effects of the present invention more clear, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention provides a tethered airship capsule cooling and heating control system, which is used to provide precise temperature control for the tethered airship capsule to ensure the stable operation of the airship under different environmental conditions. The system includes a capsule, a temperature sensor 10, an air conditioner 20 and a controller 30, the air conditioner 20 includes a refrigeration device and a heating device, and the controller 30 is electrically connected to the temperature sensor 10, the refrigeration device, and the heating device.

[0017] Specifically, the bladder is the main part of the tethered airship, which is used to contain gas to provide lift. The temperature sensor 10 is installed in the bladder, and its installation position includes at least one sensor 10 installed at the top of the bladder (the measured temperature is close to the maximum temperature in the bladder), one sensor 10 installed at the bottom of the bladder (the measured temperature is close to the minimum temperature in the bladder), and one sensor 10 installed in the middle of the bladder (the measured temperature is close to the average temperature in the bladder). These sensors 10 collect temperature data at different positions in the bladder in real time and transmit the data to the controller 30.

[0018] The refrigeration equipment is installed at the top of the capsule, including the first condenser 21, the first compressor 22, and the first evaporator 23. The first condenser 21 is arranged at the top of the outer side of the capsule, and the first evaporator 23 is arranged at the top of the inner side of the capsule. The first compressor 22 is connected to the first condenser 21 and the first evaporator 23 respectively; the heating equipment is installed at the bottom of the capsule, including the second condenser 24, the second compressor 25, and the second evaporator 26. The second condenser 24 is arranged at the lower part of the inner side of the capsule, and the second evaporator 26 is arranged at the lower part of the outer side of the capsule. The second compressor 25 is connected to the second condenser 24 and the second evaporator 26 respectively. This arrangement allows convection of the gas inside the capsule, which helps to maintain a uniform temperature inside the capsule. The exhaust gas generated after heat exchange by the air conditioner outdoor unit naturally sinks as cold air at the bottom and naturally rises as hot air at the top, both of which are far away from the capsule, which is beneficial to the operation of the air conditioning system.

[0019] The system also provides a method for controlling the temperature of a tethered airship capsule, wherein a refrigeration air conditioner 20 is arranged at the top of the tethered airship, a heating air conditioner 20 is arranged at the bottom, a sensor 10 and a controller 30 are arranged inside the tethered airship, the controller 30 is electrically connected to the sensor 10, the refrigeration air conditioner 20, and the heating air conditioner 20 respectively, and at least one sensor 10 is arranged at the top, the bottom, and the middle of the capsule, and the method also includes the steps of: S1: System initialization, setting the upper limit and lower limit of the suitable temperature range inside the capsule, starting the temperature sensor 10 to collect data, the sensor 10 collects temperature data at different positions inside the capsule in real time, and transmits the data to the controller 30; S2: The controller 30 analyzes and processes the received temperature data to determine the temperature distribution in the capsule and whether it exceeds a preset temperature range. If not, the current state of the refrigeration air conditioner 20 and the heating air conditioner 20 is maintained; S3: If the temperature at the top of the capsule is too high, the controller 30 starts the cooling air conditioner 20; if the temperature at the bottom of the capsule is too low, the controller 30 starts the heating air conditioner 20; S4: During the temperature control process, the sensor 10 continuously monitors the temperature change. When the temperature reaches a preset suitable range, the controller 30 controls the refrigeration air conditioner and / or the heating air conditioner to stop working to maintain the temperature inside the capsule stable; S5: According to different environmental conditions of the airship and flight mission requirements, the preset temperature range and the operating parameters of the refrigeration air conditioner and the heating air conditioner are manually adjusted through the controller 30.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
