FIELD: railroad transport. ^ SUBSTANCE: air conditioner represents an integral independent unity mounted under roof of passenger car and comprises tight heat-insulated housing (1) with air inlet and outlet. Housing (1) is separated by web (2) into two compartments. First compartment accommodates refrigerating compressor (3), two axial fans (4), and air condensers (5). Web (2) has openings with valves (6) arranged between outside air inlet and air condensers (5). Second compartment accommodates supply fan (7) and outside air valves (8), air filters (9), air coolers (10), water and electric calorifers (11, 12) arranged along outside airflow. First compartment incorporates additionally parallel feed evaporator coolers (13) fitted in first compartment ahead of air condensers (5). Second compartment houses recuperative heat exchangers (14) mounted ahead of air filters (9), between outside air inlet and opening in web (2). Housing bottom accommodates condensate collector (15) and water pump (17). ^ EFFECT: higher efficiency. ^ 2 dwg |
