Abstract

Automotive industry is one of the pillar industries in china, and its development will lead the development of automotive air-conditioning industry. As the application of air-conditioning technology on the automotive, automotive air-conditioning can create micro-car indoor thermal comfort environment, and maintain vehicle air temperature, humidity, flow, cleanliness, noise and pressure in the standard area of thermal comfort. It isn’t only good for protecting the health of the drivers and passenger improving the work efficiency and life quality, but also has a positive effect to increase the driving safety of the automotive. This thesis mainly expands the application of non-independent air-conditioning system on the bus. It consists of seven parts, the first part is the basic principles and structure of non-independent air-conditioning system on the bus, and it emphasizes the working principle of bus air-conditioning system, and introduces the structure of non-independent air-conditioning system and the distribution of distribution of each subassembly in system. The second part mainly introduces the heat load of bus air-conditioning system, and it also analyses and calculates the heat load. Besides, it carried out a series discussion about the energy-saving approach of automotive air-conditioning. The third and fourth parts introduce the refrigeration system and heating system of bus air-conditioning, make people know their characteristics and the composition of air-conditioning system. The fifth part is about the ventilation of non-independent air-conditioning system, air purification. It also states its purpose, as well as the maintenance of the system. The sixth part is the adopting of the non-independent air-conditioning in desiccant cooling agent, including for the type of compressor and refrigerant selection of detail. And it introduces the type of desiccant cooling agents, the choice of desiccant cooling in detail. The last part introduces the automatic protection and automatic protection of vehicle air-conditioning.
