39 automotive a/c system diagram

The A/C system is split into two sides, a high pressure side and a low pressure side; defined as discharge and suction. Since the compressor is basically a pump, it must have an intake side and a discharge side. The intake, or suction side, draws in refrigerant gas from the outlet of the evaporator.

How AC expansion valve system works Auto AC Expansion Valve Operation How does an automotive AC expansion valve system work. Many car makers now use automotive AC expansion valve in their AC systems. An expansion valve is simply a refrigerant metering device to control the rate of flow of refrigerant into the evaporator located in your dash.

Example of a car A/C condenser. By the time the refrigerant reaches the condenser, it is hot due to being pressurized. Its job is to capture this heat and transfer it out of the AC system. You can think of this part as a mini radiator, and as the gas passes through it, it radiates the heat outwards.

This system is used in summer air conditioning applications. In this system air is cooled and generally dehumidified. The schematic diagram is shown in figure. The outside air flows through the damper and mixes up with recirculated air .which is obtained from air-conditioned space.

An automotive air conditioning system works a lot like the AC system that you have at home or the office. It serves one very fundamental purpose, as well, and that is to cool you down. As a matter of fact, it would be quite difficult to imagine a modern vehicle without some means of providing a cooler and more comfortable ride especially when ...

Heat transfer and cooling in an A/C system. Rob Siegel. The diagram shows the heat transfer process for an expansion valve system, but it's very similar for a CCOT system. The main difference is that, instead of a receiver-drier on the inlet side of the evaporator, there's an accumulator on the outlet side with a pressure switch.

The capacity of the system is engineered for the type and size of the engine and the work load that it is expected to undergo. Obviously, the cooling system for a larger, more powerful V8 engine in a heavy vehicle will need considerably more capacity than a compact car with a small 4-cylinder engine.

quick-connectors onto the A/C system when eva- cuating. If only one side is connected, the system would be open to atmosphere through the other connector, making it impossible to maintain vacuum. • Be sure to turn off the manifold gauge valve imme- diately after evacuating the system. Then you may switch off the vacuum pump. PRECAUTIONS ...

Automotive electrical diagrams provide symbols that represent circuit component functions. For example, a few basic symbols common to electrical schematics are shown as: (1) Switch, (2) Battery, (3) Resistor and (4) Ground. Note the switch symbol displays an open or closed circuit path, which is what an actual switch performs.

For an air conditioning system to operate with economy, the refrigerant must be used repeatedly. For this reason, all air conditioners use the same cycle of compression, condensation, expansion, and evaporation in a closed circuit. The same refrigerant is used to move the heat from one area, to cool this area, and to expel this heat in another ...

The low pressure service port (low-side port) is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor ...

The compressor of the car air conditioning system is driven by the crankshaft of the engine through the belt drive. 2. Condenser - It is the device looks like a small radiator and is used after the compressor as it provides condensing i.e. lowers the temperature, of the high pressure and high temperature liquid refrigerant sent by compressor through forced convection provided either by ...

Air conditioning system basics - old cars weekly

All automotive air conditioning systems are (nearly) closed loops with a high-pressure side and low-pressure side. We'll start with the high-pressure side as it leads from the engine to the passenger compartment:. Compressor: The compressor is a pump driven by a belt attached to the engine's crankshaft. When the refrigerant is drawn into the compressor, it is in a low-pressure gaseous form.

The auto A/C control module receives solar radi ation intensity data from the sun-load sensor. If the solar radiation intensity changes rapidly when, for example, the vehicle enters or goes out of a tunnel, the auto A/C control module performs a correction that slows down the rate of change in the solar radiation intensity recognized by itself.

Any AC system requires a refrigerant, such as R-134a. Your vehicle's compressor, powered by the serpentine belt, compresses the refrigerant into a liquid, putting it into a high-pressure state. This pressure forces the liquid out of the compressor through the hoses in your AC hose assembly, which carry refrigerant through the system.
