Engineering-truck-mounted air conditioner

Abstract

The invention discloses an engineering-truck-mounted air conditioner. The air conditioner comprises a shell, a protection layer is arranged on the outer side of the shell, and a water bath system is arranged in the shell; the water bath system comprises a water bath cavity, an air inlet pipe is arranged on the side face of the water bath cavity, the air inlet pipe is provided with a check valve and a purification cavity, the check valve is arranged at the top of the purification cavity, an air inlet port is formed in one end of the air inlet pipe, a water bath pipe is arranged at the other endof the air inlet pipe, and a filter screen is arranged on the side face of the air inlet port. According to the air conditioner, by the arrangement of the water bath system, air passes through the filter screen to enter the air inlet pipe and then is preliminarily purified by an activated carbon filter screen in the purification cavity, the purified air enters the water bath pipe and then enterswater from the water bath pipe, tiny dust in the air can be dissolved in the water, and gas can become bubbles to float and break; thus, impurities and dust in the air are removed through preliminarypurification and secondary purification, and the air cleaning effect is achieved in cooling or heating.

Description

technical field [0001] The invention relates to the technical field of air conditioning equipment, in particular to a vehicle-mounted air conditioner for an engineering vehicle. Background technique [0002] Engineering vehicles are the backbone of a construction project. Because of their appearance, the progress of construction projects has doubled and manpower has been greatly reduced. Common engineering vehicles include: heavy transport vehicles, large cranes, excavators, bulldozers, road rollers, loaders, electric power Emergency repair vehicle, engineering emergency vehicle, government special engineering vehicle, off-road engineering vehicle, electric welding engineering vehicle, armored engineering vehicle and oxidant sewage treatment engineering vehicle. [0003] Basically all engineering vehicles are equipped with air conditioners, but the existing air conditioners for engineering vehicles still have some shortcomings. Because engineering vehicles usually work in an...

Problems solved by technology

[0003] Basically all engineering vehicles are equipped with air conditioners, but the existing air conditioners for engineering vehicles still have some shortcomings. Because engineering vehicles usually work in an environment with high temperature, dust and vibration, a large amount of dust will enter when the driver opens the door. Dust accumulation is formed in the cab. When the car air conditioner is turned on, the dust in the cab will be sucked into the air conditioner along with the air circulation, which will cause dust accumulation inside the air conditioner, which will reduce the cooling or heating effect of the air conditioner and be discharged at the same time. The hot or cold air contains a certain amount of dust, which is not conducive to human health
