Structure surface anti-condensation temperature adjusting system and control method

Abstract

The invention discloses a structure surface anti-condensation temperature adjusting system and a control method. The structure surface anti-condensation temperature adjusting system comprises a connecting channel for connecting the indoor space with the outdoor space, a plurality of adjusting spaces are sequentially arranged in the connecting channel in the extending direction, and a temperature adjusting assembly is arranged in each adjusting space; and each temperature adjusting assembly comprises an air conditioner unit arranged at the upper portion of the corresponding adjusting space and a heating unit arranged in a connecting channel main body structure, the heating units and the air conditioner units are both connected with a control unit, and the control unit is further connected with a monitoring device. Through the partition arrangement of the adjusting systems, a temperature gradient is formed in the spaces formed by all the units, and the purpose of comfortable transition is achieved; and by heating the main body structure at the cost of sacrificing a small amount of heat, it is guaranteed that the structure surface is not condensed, particularly after the anti-condensation design is carried out on the ground position, the phenomenon that passengers fall and are hurt due to wetness and slippery can be avoided, and meanwhile equipment, pipelines and supports and hangers are prevented from being rusted.

[0002] my country has a vast territory, a large span between north and south latitudes, a long depth from the coast to the inland, and large climate differences in various regions. For cities with high outdoor air relative humidity in summer, the entrances and exits of subway stations, railway stations and outdoors are directly connected to the station during certain periods of summer. Condensation is prone to occur on the inner surface of structures such as buildings, underground garages, etc. Condensation on the inner surface of the structure will cause serious harm to daily operations. At the same time, the ground is wet and slippery, and the staff and passengers are prone to fall and cause safety hazards; when the condensation phenomenon is serious, continuous condensation will occur, and the condensed water will continue to drip, resulting in short circuit of electrical equipment and failure to operate normally. Increase operation and maintenance The risk of electric shock for personnel, and the humid environment can easily lead to accelerated corrosion of equipment, pipes, and hangers, which affects life expectancy and poses safety hazards

[0003] There are two ways to fundamentally solve the problem of condensation on the surface of the structure. The first is to dehumidify the air so that the dew point temperature is lower than the surface temperature of the structure. However, since the above condensation area is directly connected to the outside, natural wind, platform Due to factors such as air leakage from the screen door, there is always the phenomenon of outdoor air intrusion, and it is impossible to isolate the connection with the outside world. Even if air curtains, dehumidification equipment, etc. are used, the effect is not obvious; the second way is to increase the surface temperature of the structure, such as heat insulation for the enclosure structure The treatment reduces the heat transfer with the surrounding soil to a certain extent, so that the surface temperature of the building structure can be raised quickly when summer comes, and the condensation phenomenon is reduced. However, this method also sacrifices the heat storage and cold storage function of the underground structure throughout the year, and the The method cannot completely avoid condensation in some severe humid weather

[0004] To sum up, the existing technology has certain defects in dealing with the problem of condensation on the surface of the building directly connected to the outside, and it is impossible to completely avoid the occurrence of condensation. Therefore, we need to design a structure surface anti-condensation temperature adjustment system and control method to solve these problems
