Abstract

Provided is a double-air-inlet type drainage anti-reverse-suction air conditioner. An evaporator of the double-air-inlet type drainage anti-reverse-suction air conditioner is arranged at the upper endof the rear portion of the inner side of a box body. An electric heater is arranged at the front end of the evaporator. A ventilator is arranged at the upper end of the front portion of the inner side of the box body. A fresh air fan is arranged at the bottom end of the rear portion of the inner side of the box body. An air inlet of a compressor is connected with an air outlet of the evaporator through a pipeline. An air outlet of the compressor is connected with an air inlet of a condenser arranged at the front portion of the inner side of the box body through a pipeline. The air inlet of the condenser is connected with the evaporator through a pipeline through a drying filter. A high-pressure switch is arranged on a pipeline between the compressor and the condenser. A low-pressure switch is arranged on a pipeline between the compressor and the evaporator. A water storage disc is arranged at the bottom of the evaporator. A double-U-shaped drainage pipe is connected to the bottom of the water storage disc. According to the double-air-inlet type drainage anti-reverse-suction air conditioner, indoor and outdoor air inlet can be achieved, and meanwhile, the water drainage anti-reverse-suction cooling effect is good; and the local high temperature of the interior of a cab, a mechanical room and an electric appliance room in a locomotive can be rapidly reduced.
