The invention provides a liquid loop circulating refrigeration method for a sealed cabin in a vacuum environment. The liquid loop circulating refrigeration method comprises the following steps that I, gas carrying heat in the sealed cabin is transmitted to a first heat exchanger; II, the first heat exchanger transfers heat carried by the gas to a first liquid medium, and the cooled gas is transmitted to a sealed cabin; III, the flow of the first liquid medium in the liquid loop is adjusted, and the first liquid medium carrying heat after flow adjustment is transmitted to a second heat exchanger; IV, the second heat exchanger transfers heat carried by the first liquid medium to a second medium and transfers the cooled first liquid medium to the first heat exchanger; and 5, the steps I to IV are repeated to complete refrigeration in the sealed cabin in the vacuum environment. According to the technical scheme, the technical problem that in the prior art, heat dissipation cannot be conducted on the sealed cabin in the vacuum environment is solved.
Description
technical field [0001] The invention relates to the technical field of refrigeration of a sealed cabin in a vacuum environment, in particular to a liquid loop circulation refrigeration method for a sealed cabin in a vacuum environment. Background technique [0002] At present, the temperature control of the air in the cockpit of a manned spacecraft is an active temperature control technology based on forced convection heat transfer. There are two types of such systems: liquid circulation and gas circulation. Driven by pumps or fans, the fluid draws out the internal heat of the spacecraft, and flows through the external heat radiator to the outer space. The cabin temperature control of modern civil aviation passenger aircraft mainly adopts the air circulation refrigeration method. The high-temperature and high-pressure gas drawn from the engine is initially cooled by a series of heat exchangers, and then expanded and cooled by the cooling turbine, and the low-temperature and...
