关于工程车辆驾驶舱采暖功率计算的探讨

Discussion on Cab Heating Performance of Construction Vehicles

研究工程机械受到寒冷环境影响及自身影响,确定驾驶舱采暖功率。以某一型号的挖掘装载机为例,通过理论计算和实际试验,验证暖风系统的采暖制热功率,为工程机械驾驶舱热负荷计算提供一种依据。

The paper studies influences of cold weather to the heating performance of air conditioning system on construction vehicles and confirms the heating power of the air conditioning system ; takes a model of backhoe loader as the example, verifies the heating power of the air conditioning system through theoretical calculation and actual tests, which provides a foundation for the thermal load calculation in the cab of construction vehicles.
