The invention provides a liquid loop circulation refrigerating system for a sealed cabin in a vacuum environment and a train, the system comprises a first heat exchanger, a first power unit, a second power unit, a second heat exchanger, a second medium storage tank, a third power unit and a flow regulating valve. The first heat exchanger comprises a first liquid medium, the first power unit is used for conveying air in the sealed cabin to the first heat exchanger, the second power unit is used for conveying cooled air to the sealed cabin, and the second heat exchanger is used for transferring heat of the first liquid medium to the second medium and conveying the cooled first liquid medium back to the first heat exchanger. The third power unit is used for conveying the first liquid medium carrying heat to the second heat exchanger, and the flow adjusting valve is used for adjusting the flow of the first liquid medium entering the second heat exchanger. By means of 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 system and a train 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-tem...
