Description

A kind of bus air conditioning auxiliary system

technical field

The utility model relates to the field of energy saving, in particular to an air-conditioning auxiliary system for a bus.

Background technique

The bus uses fuel to generate electricity and electricity to start the air conditioner, but the operation of the air conditioner is a mechanical process, that is, the electrical energy needs to be converted into mechanical energy. The shape of the bus is heavier than that of the car, and it is generally a cuboid, and its shape design does not take too much into account the influence of air resistance on the vehicle speed.

The principle of bus refrigeration is to use a compressor to compress the refrigerant, convert the refrigerant into a liquid state, and release a large amount of heat at the same time, so that its temperature rises significantly. At this time, the refrigerant transfers heat to the outside through the heat conduction surface, and a large amount of heat released by the refrigerant is transferred to the outside world, and then through decompression, the refrigerant is vaporized, and a large amount of heat is absorbed when the refrigerant vaporizes. At this time, the refrigerant contacts the air in the car through another heat transfer surface, absorbs a large amount of heat in the car, and then blows the temperature-regulated air into the cabin through the fan. When heating is required, the above process can be controlled to transfer a large amount of heat from outside the car to the inside of the car.

The existing air-conditioning system of the bus requires fans to blow the temperature-regulated air into the cabin. On the one hand, the number of fans is limited, and the air flow into the cabin is uneven, which is easy to make passengers feel uncomfortable; on the other hand, the fan itself Additional electricity is required.
