Hino buses have insufficient air-conditioner and frost on the evaporator surface.
  • Automotive

A Hino RC421P bus air conditioner is in use, each evaporator mouth blow out of the cold air is not enough, and evaporator surface is covered with thick frost. According to analysis, the thermal conductivity of the frost is far lower than that of the ordinary metal. When the evaporator is formed on the surface of the evaporator, it is difficult to transmit the heat in the car to the refrigerant in the evaporator tube; in addition, the thick frost is wrapped in the evaporator, which also hinders the diffusion of the evaporator's cold air into the car, thus causing the inadequacy of the air-conditioner in the car.
