Abstract

The invention discloses a rail transit refrigeration system and an intelligent adjustment method and device thereof. The method comprises the steps that a load demand in a field after a preset time period in future is estimated, and a deviation between the load demand after a preset time period and a load demand in a current moment field is determined; operating parameters of the refrigeration system is adjusted according to the deviation of the load demand; and according to the target temperature and the return air temperature, obtained after the operating parameters are adjusted, of the refrigeration system, the operating parameters are continuously adjusted to meet the load demand in the field after the preset time period. Therefore, when the flow rate of persons changes rapidly, the operating parameters of the refrigeration system can be adjusted in time according to the deviation of the load demands, and the purpose of improving the user comfort while ensuring energy efficiency isachieved. After the operating parameters are adjusted according to the deviation of the load demands, adjustment can be continuously carried out according to the return air temperature, the delay problem caused by the fact that the refrigeration system is far away from a user area can be solved, so that the adjustment is more accurate.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit refrigeration system and its intelligent adjustment method and device. Background technique [0002] At present, the construction of large-scale rail transit hubs in domestic cities is developing rapidly, and the construction of various supporting facilities for rail transit hubs represented by subway stations and railway stations is also particularly important. Among them, the selection of refrigeration systems is the most important. However, the requirements of the refrigeration system for rail transit are somewhat different from those of other stable central air-conditioning units. In rail transit, the time-sharing extreme of the flow of people will cause drastic changes in the cooling load. If it cannot be adjusted in time, it will not only cause waste of electricity, reduce energy efficiency, but also have a negative impact on passenger comfort. And cons...
