Description

Engineering vehicles usually work under the environments of strong sunlight (glass walls are all around for convenient viewing), high temperature and large vibration, and common household air conditioners often cannot work normally under the conditions.
The existing engineering vehicle air conditioner is divided into a hydraulic starting type air conditioner and an engineering vehicle power driving type mechanical air conditioner according to a driving mode. The hydraulic air conditioner utilizes the power source of the hydraulic system branch of the engineering truck to drive a hydraulic motor, and the hydraulic motor drives an air conditioner compressor to work. The hydraulic air conditioner has the disadvantage that the work must be synchronized with the engineering vehicle, and the working capacity of the engineering vehicle is unstable because the air conditioner uses the power source of the engineering vehicle. The engineering vehicle power driving type mechanical air conditioner is directly driven by the engineering vehicle engine, and consumes the power of the engineering vehicle, so that the working system capacity of the engineering vehicle is weakened. The compressors of the two air conditioners are special air conditioner compressors for vehicles, and the technology is complex and the manufacturing cost is high; when the engineering machinery is waiting, the engine of the engineering vehicle must be started due to the starting of the air conditioner, so that a large amount of oil is consumed, and the waste gas is discharged to cause great waste of resources. The power of the engine is mostly derived from the engine, when the air conditioner works, the engine drags the hydraulic pump to drive the compressor to operate, but if the engineering vehicle is in a stop state, the engine can only be started to start the air conditioner, so that the fuel is wasted, the oil consumption and the work consumption can be increased when the air conditioner is started in the working state of the engineering vehicle, and the operation of the air conditioner depends on the engine. And the traditional air conditioner for the engineering vehicle at present can not change the working state of the air conditioner compressor according to the change of the temperature of the annular wall.
Aiming at the defects, an engineering vehicle electric integrated air conditioner which utilizes an automobile storage battery as a kinetic energy equipment is appeared in the market, the refrigerating effect of the integrated electric air conditioner also cannot meet the requirements of engineering vehicles, in particular the requirements of large engineering vehicles (such as large cranes), and the integrated electric air conditioner is troublesome to install, has poor reliability and stability and is inconvenient to maintain.
