Problems solved by technology

[0003] In actual use, there are often scenes where only the necessary accessories of the air conditioning system are required to work. At this time, the traveling mechanism and operating mechanism are all in a non-working state and do not need power, and the power output by the main engine far exceeds the energy consumption of the air conditioning system. , leading to a serious waste of
At the same time, the main engine is in a state of low load and continuous operation for a long time, which will affect the service life of the main engine

Abstract

The invention provides an engineering vehicle with an air-conditioning system, comprising a chassis, a main engine, an auxiliary engine, a controller and an air-conditioning system, the main engine, the air-conditioning system and the auxiliary engine are all arranged on the chassis, and the controller is connected with the The main engine and the auxiliary engine are connected; in the first working condition, the controller controls the main engine to work and provides power to the air-conditioning system; in the second working condition, the controller controls the auxiliary engine to work and provides power to the air-conditioning system . Compared with the prior art, when only the air conditioning system is working, it does not need to rely on the power of the main engine, which prevents the main engine from working continuously for a long time and prolongs its service life. Additionally, energy wastage can be reduced by using an auxiliary engine to power the air conditioning system.

Description

technical field [0001] The invention relates to engineering vehicle manufacturing technology, in particular to an engineering vehicle with an air conditioning system. Background technique [0002] Generally, in order to provide a more comfortable working environment, engineering vehicles are equipped with an air-conditioning system, which can adjust the temperature in the cab as required. On the existing engineering vehicles, the power of the air conditioning system is provided by the main engine, and part of the power output by the main engine is provided to the traveling mechanism, the working mechanism, etc., and the other part is provided to the air conditioning system. [0003] In actual use, there are often scenes where only the necessary accessories of the air conditioning system are required to work. At this time, the traveling mechanism and operating mechanism are all in a non-working state and do not need power, and the power output by the main engine far exceeds t...
