The nozzle assembly 6 is communicated with the induction type atomizer 5, the induction type atomizer 5 is communicated with a liquid bag 35 of the fresh air processor 36 through a pipeline, and the circulating water pump 3 is arranged on the pipeline between the liquid bag 35 and the induction type atomizer 5.

Description

technical field [0001] The present invention relates to a rail vehicle air-conditioning device [hereinafter referred to as the air-conditioning system] that uses the exothermic end of the refrigeration system [hereinafter referred to as the condenser] to heat and humidify fresh air, and uses the heat-absorbing end [hereinafter referred to as the evaporator] to cool down and dehumidify the return air of the carriage . Background technique [0002] Subway carriages are generally closed environments, and the density of people is very high, resulting in the generation of various pollutants in the carriages. Especially during the epidemic, germs are easy to cross-spread in the carriages, which poses a greater threat to people's health. risk. According to the actual situation of the carriage, the reasonable design of the air-conditioning system of rail vehicles that has the function of cooling and heating, can prevent the cross-spreading of germs, and is energy-saving is in line ...
