An air conditioner system of a railway vehicle, comprising a carriage (1), wherein an outdoor compression/condensation unit (2) and a vehicle-mounted power supply (7) are separately fixed on the outer top of the carriage (1), a plurality of indoor evaporation units (3) is successively fixed on the inner top of the carriage (1) along the length direction of the carriage (1), the indoor evaporation units (3) are separately and circularly communicated with the outdoor compression/condensation unit (2) through coolant pipes (4), the air outlet direction of air outlets of the indoor evaporation units (3) faces downwards, and the indoor evaporation units (3) are communicated with air in the carriage (1) through an air return pipe (5) fixed in the carriage (1). The evaporation units of the air conditioner system are arranged in the carriage, and a fan on the top of the carriage is canceled additionally, so that the structure of the air conditioner system on the top of the carriage is greatly reduced, and not only is the weight of the carriage reduced and the center of gravity of the carriage lowered, so as to make the carriage more stable in running, but also the air resistance when the carriage runs can be decreased. |
