1 conditioning system
Modern refrigeration system of an air conditioning system, heating systems, ventilation and air cleaning device and control system.
generally formed predominately of automotive air conditioning compressor, the electronic control clutch, a condenser, an evaporator, an expansion valve, a receiver drier, duct, the condenser fan, the vacuum solenoid valve, and the idle control system components. Automobile air-conditioning of the high pressure line and a low-pressure line. It includes a compressor output-side high pressure side, the high-pressure pipe, a condenser, a drier and a liquid conduit; low-pressure side comprises an evaporator, the accumulation, a return line, the input side of the compressor and compressor oil pool.
is actually a drier storage means impurity refrigerant and the refrigerant absorbing moisture. On the one hand, it is equivalent to the fuel tank of the car, was leaked refrigerant extra space to add refrigerant. On the other hand, that it is like a air cleaner, filter out impurities doped in the refrigerant. Also drier with some silicone material acts to absorb moisture.
Although the condenser and the evaporator are not the same name, but similar structures. They are covered with a metal sheet for heat dissipation in a row around the bend pipe, in order to achieve devices with outside air heat exchange pipe material. It refers to a condenser for condensation refrigerant heat pipe in which a liquid from the gaseous cemented. Radiator The principle is similar to the engine (only difference is that the water tank has been the only liquid?, So it is often installed at the front, with tanks together to enjoy the cool breezes from the front of a word to cool the condenser is Shucks , so that condensation heat. evaporator and condenser, on the contrary, it is a refrigerant from the liquid into gas (i.e., evaporator) to absorb heat properties.
automotive air conditioning system of the vehicle to avoid the open air at high speed , is recommended to turn at lower speed. when starting or shutting down the engine, air-conditioning switch should be placed in the closed state when the cabin temperature is high, the air conditioning switch should be opened, is placed at the lowest temperature, air volume to the maximum opening, the temperature dropped and then adjust the air volume switch. In order to maintainGood driving, do not smoke in the car. If you use the air conditioner longer need to open the window for ventilation. Replace the air filter regularly.
function
air-conditioning system, the type and composition of
Modern automotive air conditioning has four functions, any of which are meant to passengers feel comfortable.
(1) The air conditioner in the vehicle interior temperature can be controlled, both heated air can be cooling air, so the temperature inside a control to a comfortable level;
(2) Air conditioning is moisture in the air can be discharged. Human sweat absorbing drying air, causing more comfortable environment;
(3) The air conditioner may be inhaled fresh air, with a ventilation function;
(4) the air conditioner can be filtered to exclude air dust and pollen.
Type automotive air conditioning system
1, according to the driving modes: Detached (a dedicated engine to drive the compressor, cooling capacity, stable, but high cost, large size and weight, and more for large and medium-sized passenger cars) and non-independent (air conditioning compressor driven by an automotive engine, cooling performance influenced by the engine, poor stability, used for minibuses and cars).
2, according to the air conditioning performance is divided into: a first single function type (refrigeration, heating, ventilation systems are each mounted, a separate operation, noninterference, used for passenger cars and trucks on the large) and being of one-piece (cooling, heating, ventilation and air duct common blower, control the same control board, can be divided into temperature controlled mixing warm and cold air, respectively, and a combined work of cold or warm wind can operate simultaneously work multiple mixed temperature controlled car) .
When the control mode is divided by (toggle function keys on the control panel temperature, wind speed, wind direction control) and electrically controlled pneumatic manual adjustment (by the vacuum control means, a good air-conditioning function election key, temperature and air flow can be automatically controlled within a predetermined temperature).
3, according to the control modes: automatic adjustment (using the calculated comparison circuit, by presetting of sensor signal and the control signal adjusting means to automatically adjust the temperature and air volume) and a computer-controlled automatic adjustment (to micro-Machine control center, interior air to achieve all-round, multi-optimal control and regulation).
arrangement
Air Conditioning System
arrangement of different types of air-conditioning system vary. Car is currently widely used integrated heating and air-conditioning systems. Pattern is arranged to an evaporator, a radiator heater, a centrifugal blower, and the like are assembled control mechanism, referred to as the air conditioner assembly.
automotive air conditioning system composed of
Modern refrigeration system of an air conditioning system, heating systems, ventilation and air cleaning device and control system.
automotive air-conditioning controller, the control device belonging to a motor vehicle air conditioning apparatus. Adjusting the automotive air conditioning system having a refrigeration ventilation, defrost function. All equipment installed securely, the control means and actuating means rotating flexible, comfortable, safe and reliable performance.
air conditioning systems maintenance and repair
judgment air conditioning system works is good is actually very simple, if found defective air-conditioned, a small amount of wind, or simply no refrigeration and so on , it is necessary to check whether the normal operation of the various components, whether the lack of condensing agents. Condensing agent must be added in accordance with the model number on the car’s manual. These can get in a professional shop. For us car owners, more noteworthy is that, on a regular basis to replace the air conditioning filter, usually traveling in city traffic, about three thousand kilometers we need to replace the air filter, so not only can make the intake system cleaner, can also be avoided because the air conditioning filter blockage caused by decreased cooling capacity.
Summer large temperature difference between inside and outside the car, when entering the car, the air conditioning will not immediately adjust the temperature is too low, you can use the amount of natural wind scattered wind and hot air in the car, then the car will not Close all windows, turn on air conditioning, and other body gradually adapt after the air conditioning temperature modulation need to close the window. So our bodies would not be due to external sudden drop in temperature caused discomfort.
the air conditioning, it is not as low as possible, the body most comfortable temperature is around 23 degrees Celsius, in the sunny summer afternoon, air-conditioning and it is not too low, not only to resist the summer sun, and ensures not to the body where the ambient temperature is too low, thereby turningCause ldquo; KongDiaoBing rdquo ;, but also in response to the national energy conservation, low-carbon environment of the call.
at the time of the open air, the passenger is best not to smoke in the car, because the air conditioner is turned on, the car air circulation in a relatively closed environment, the first flue gas is not easy to shed, followed by minor smoke the particles will be attached to the intake air conditioner filter, resulting in long-term car smell.
regular professional cleaning and disinfection of air conditioning systems in addition to smell conservation.
