Step In Filling Summer Air
Beijing recently can be described as a step
summer, when daytime maximum temperature reaching a maximum 28 , the temperature in other parts of the South had risen to around 24-28 . Summer, and as temperatures rise, many drivers will be driving trip air conditioning when opened, then some drivers will find how my air conditioner not cold? There are many soil from the air vent out, the face of these circumstances should how do?
Air conditioning system working properly for the users, in the open air conditioning system should first wash before the air duct. The easiest way is: will the windows, door open, with a wet towel or cotton net blocking the air vent on the air blower at maximum speed, so the dust will absorb in the towel. In addition, you can spray a certain amount of air-conditioning duct cleaning agent, with high pressure air blow gun into the air by various air-conditioning blowing against the direction of the outlet 2 to 3 times to achieve the rapid cleaning purposes.
Mentioned refrigeration air conditioning system is not the reason, it is mainly in the old car body, due to longer part of some loosening of the joint air-conditioning, or pipeline leak, leading to R-134a ( Refrigerant ) To disappear. This article will focus on Car Add R-134a air-conditioning systems and leak turnover precautions.
Automotive air conditioning works In the introduction, we first look at automotive air conditioning works. In fact, simple to understand for the air conditioning system is the vapor into a liquid by the liquid into a gaseous process. As shown below, automotive air conditioning generally the main by the compressor, condenser, pressure maintenance valve port, expansion valve, evaporator, suction shut-off valves, low pressure service valve port, storage fluid dryers, pipe, idling devices and control systems composition.
Car air condition low pressure piping and piping. High-pressure side of the output side of the compressor, high pressure piping, condenser, drier and liquid pipelines; low side, including the evaporator, aggregators, back to the trachea Road, compressors and compressor oil input side of the pool. Here we have simply,
under the effect of each component.
Compressors: air conditioning refrigeration system is the heart, by definition, the compressor is compressed from the role, its role is that we just mentioned, to complete the refrigerant changes from gas to liquid process, to the refrigerant condensing heat disclosure purposes. While the air-conditioning systems, compressors or pipeline operating pressure within the media source, without it, the system not only cooling but also lost power to run.
Compressor Category: Piston: Piston-type compressors resembles the structure of the engine, there is the crankshaft, connecting rod, piston, cylinder etc., often long-distance cargo moving car or bus use.
Swashplate: mainly used in our common cars, small commercial vehicles to use. Because of its small size, light weight, easy to install small engine room arrangement, so widely used.
Although the above two compressors in the design of the structure is quite different, but they are the rotational kinetic energy from the engine into the reciprocating piston compressor, so that the formation of pressure pipe air conditioning system to achieve compression The purpose of refrigerant.
Pipeline: both high-pressure pipes, or low pressure pipes, metal pipes must be used. Because some pressure to inject the refrigerant, in particular, high-pressure section of the system needs to have a higher resistance to high-pressure pipeline requirements.
Drier (carbon canister): is actually a cooling agent and absorption refrigerant storage water impurities devices. On the one hand, it is equivalent to the car tank, for the refrigerant leak out of space to add more refrigerant. On the other hand, it is also like the air filter so that filters out impurities in the refrigerant in the doping. Also drier with some silicone material, play a role in absorbing water.
Condenser and evaporator: Although they are not the same as it is called, but the structure is similar. They are bent around a row of heat pipes covered with sheet metal used as a means to achieve the outside air and the pipe material of heat exchange devices. Condenser refers to the refrigerant heat pipe cemented liquid from the gas. Evaporator and condenser on the contrary, it is the liquid into a gaseous refrigerant absorbing heat from the place.
