Temperature control system of near space sealed cabin

Abstract

The invention provides a temperature control system of a near space sealed cabin. The temperature control system comprises a cabin wall heat exchanger, a cold accumulation heat exchanger, a first bypass pipeline, a gas-liquid heat exchanger and an acquisition controller, wherein the cabin wall heat exchanger is arranged on a cabin wall of the sealed cabin for obtaining an out-cabin cold source; the cold accumulation heat exchanger is internally provided with a cold accumulation working medium, connected with an output end of the cabin wall heat exchanger through a liquid pipeline at an input end and provided with a first control valve at the input end or an output end; the first bypass pipeline is connected to two ends of the cold accumulation heat exchanger in parallel through liquid pipelines and provided with a second control valve; the gas-liquid heat exchanger is used for exchanging heat with the internal part of the cabin, connected with an output end of the cold accumulation heat exchanger through a liquid pipeline at an input end and connected with the input end of the cabin wall heat exchanger through a liquid pipeline at an output end; and the acquisition controller is used for controlling the first control valve and the second control valve. The temperature control system can satisfy temperature demands of a near space sealed cabin manned flight in ascending, stop and descending processes, and solves the problem of influence on the in-cabin temperature by external environment change distance.

Description

technical field [0001] The invention relates to the field of near-space aircraft, in particular to a temperature control technology for a sealed cabin in a near-space. Background technique [0002] With the development of modern science and technology, the unique resource advantages of near space (Nearspace, 20-100km altitude) have become the focus of attention of all countries. The hotspots that are competing for research and development, manned travel in adjacent space, high-altitude experiments, photographic exploration, navigation and other fields have gradually been developed and utilized. Among them, short-term manned travel in adjacent space, as a new tourism industry, has gradually attracted people's interest. However, in order to ensure the safety of manned travel and improve the comfort of personnel, it is necessary to do a good job in the corresponding temperature control of the airtight cabin. However, due to the unique environmental factors such as air temperat...
