  • Publication number: 20230064579
    Abstract: A bus heating system and a method of controlling the same, is configured for controlling a water-heating-type main heater unit and a heat-pump-type auxiliary heater unit in conjunction with each other for heating an interior of a bus, improving the efficiency of operation of the main heater unit while reducing the number of switch operations. The bus heating system includes a water-heating-type main heater unit configured to heat an internal bottom area of the bus, a heat-pump-type auxiliary heater unit configured to heat an internal roof area of the bus, and a controller configured to control operations of the main heater unit and the auxiliary heater unit in conjunction with each other based on a set target internal temperature (Ttarget), a measured outside air temperature (Toutside), a measured internal temperature (Troom), and a main-heater-unit refrigerant temperature (Trefrigerants).
