Further judging whether the temperature reaches a preset temperature range after cooling, wherein if the preset temperature range is met, other cooling systems do not need to work and the temperature requirement in the station room is met; if the preset temperature range is not met, the air conditioning system is assisted, and the temperature requirement in the station room is finally met. And judging whether the temperature range preset in the station room is met or not according to the result detected by the temperature sensor in the station room.
As shown in fig. 6 (b), the cooling control schematic diagram in the absence of sunlight differs from that in fig. 6 (a) in that: when the solar chimney system works, the heat stored in the heat storage wall body is utilized to increase the thermal lift force in the solar chimney and discharge hot air, so that the aim of cooling the high-speed rail station house is fulfilled.
