how automotive ac works
The low side low connects the evaporator back to the compressor. An expansion valve is simply a refrigerant metering device to control the rate of flow of refrigerant into the evaporator located in your dash.

Thermal expansion valve or orifice tube.
. Through that loop runs refrigerant which is what really does the work of cooling down the air. Most recharging hoses come equipped with a pressure gauge and allow you to check it to determine if the system needs refrigerant. Now if the pressure is holding steady congratulations.
The car AC works in two cycles. Compressing the Refrigerant into Gases. How a car ac ac system works how does an ac system work how do car ac systems work what are the components of an ac system how does an ac compressor wo.
You dont want to get caught in 90 degree weather without your cars ac working properly. The two points that separate the sides are the compressors reed valves and the expansion valve at the evaporator. Instead of being water-filled or needing ice to cool the air a portable car AC will work in a similar fashion to a home AC unit.
In the illustration below youll see that low pressure gas flows out. The compressor raises the pressure and temperature of the refrigerant gas and sends it to the condenser coil where it is converted to a liquid. This transfers heat to the refrigerant from the air blown across it which is a vital part of the auto AC in cooling your car.
In many makes air conditioning cycles automatically when the defrost setting is chosen. Firstly Air Conditioning is the process of making the air comfortable for the cars occupants. Your air conditioning system is made up of a compressor a condenser an evaporator or drier refrigeration lines and a couple of sensors here and there.
Cools the air entering the passenger compartment. The compressor is what takes the refrigerant the gas and pressurizes it so it will absorb heat and cool the air. The easiest way to explain how the system works is to trace the refrigerant as it flows through the system-.
There are five main parts of a car AC. We will explain in simple terms how automotive ac works. Having a good understanding of how the components work can help to explain the methods of repairs in the air conditioning system.
The process works in balancing the AC cycle following the compressor. This part of auto AC basics is somewhat of a nozzle and functions to simultaneously drop the pressure of the refrigerant liquid meter its flow and atomize it within the auto AC. Once the gas is in the pump it is put under extreme pressure 250psi-400psi and is forced out to the condenser.
Still compressing and evaporating refrigerant to produce cold air just on a. Lowers the temperature of the high pressure and high temperature liquid refrigerant sent by compressor through forced convection provided. Some individuals do not know how a cars air.
In the modern world it is difficult to find a current car without an AC system. A car air conditioning system works like a home or office AC system. 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.
An automotive air conditioning system works a lot like the AC system that you have at home or the office. The compressor is a pump driven by a belt attached to the engines crankshaft. It actually takes the heat and moisture out of the air that is already in your car leaving behind cooler air.
Condenser It is the device looks like a small radiator and is used after the compressor as it provides condensing ie. The refrigerant is drawn into the compressor as a low-pressure gaseous form. Get Money Saving Offers Schedule Service At Your Local Quick Lane.
It serves one very fundamental purpose as well and that is to cool you down. AC systems are split into two sides the low pressure side and the high pressure side. A fan blows indoor air across the cold evaporator coil where.
With warmer temperature headed our way you want to be sure your ac works. Up to 8 cash back Air conditioning has two main purposes. Then the refrigerant travels back indoors and enters the evaporator coil.
A vehicles air conditioning system does not create cold air. This is the heart of your AC system. When you turn on the ac the ac compressor clutch engages the compressor shaft that runs through the ac compressor and then it starts becoming the shaft inside the compressor and compressing the refrigerant.
The system is full and should not be charged good job and close up shop. Heres what they do. It pulls the humidity from the windshield to improve your visibility.
How does an automotive AC expansion valve system work. The freonrefrigerant resides in the ac. See Service Advisor For Details.
Ad Get The Works Synthetic Blend Oil Change More. Here the liquid refrigerant evaporates and cools the indoor coil. It is crucial more so during the warm weather.
The high side hose connects the compressor to the condenser from the condenser to the expansion valve or orifice tube which are both located in front of the evaporator. Each of the parts is connected by tubing or hoses to form a closed loop. The expansion valve or orifice tube do basically the same job the system will have one or the other.
Many car makers now use automotive AC expansion valve in their AC systems. Compressors cannot compress liquids only gasses. The primary purpose of the car air conditioner is to make the cabin ambiance comfortable for the occupants.
The compressor of the car air conditioning system is driven by the crankshaft of the engine through the belt drive. The best portable air conditioner has multiple power source options such as an adapter 12v car power supply or rechargeable batteries. The system gives you a comfortable and relaxed ride especially during the summer season.
Removes the moisture from the air so it feels more comfortable inside the vehicle. Crank your engine and turn the AC on high cool high fan. Refrigeration and Evaporative Cooling evaporation and condensation.
