Study on distribution proportion of solar radiation in air-conditioned bus;

The distributing profile and concentration level inside new air-conditioned buses with 53 seats have been determined using the method of thermal desorption-capillary GC/MS under vehicle static conditions.

The grounding protection mode of the AC 380 V air-conditioned passenger cars as well as the harm of different grounding protection ways existing simultaneously is described.

In view of the fire disaster caused by such troubles as the electrical element trouble and the loosening of the amphenol connectors in the power supply transverse box for air-conditioned passenger cars,the design scheme of the temperature monito- ring system in the power supply transverse box is put forward.

The disposition of the troubles in inspection and repair of the programmable controller (PLC) on air-conditioned passenger cars is described.

This paper introduces factors influencing energy consumption in air conditioning bus and explores several energy saving ways.

This paper analyses the ventilating system in an air conditioning bus, and points out the non reasonableness of fan construct and usage, which not only makes ventilating effect non visible but also wastes the energy.
