The compressor is the pump in the system.The compressor compresses the refrigerant in a gas state. HubPagesCopyright © 2020 HubPages Inc. and respective owners.As a user in the EEA, your approval is needed on a few things. The refrigerant leaves the compressor as a gas thru the discharge port. DIY Auto Service: Air Conditioning (AC) System Operation with TXV or Orifice Tube This is usually a larger size line. (Liquids can’t be compressed) The compressor also increases the pressure and temperature of the refrigerant. Automotive air conditioning. Any AC system requires a refrigerant, such as R-134a. New vehicles 1994 and newer came with R-134a refrigerant.Each refrigerant has compatible refrigerant oils that should be used. "Substitutes in Motor Vehicle Air Conditioners."

One BTU is approximately the heat given off by one wooden match. Technological Leadership. Using your hands to feel the lines can be a quick way to see if there is a problem with the AC; Are the lines The AC system forms a loop that starts at the compressor. If the pressure is high so is its temperature. This system also has a Receiver Drier on the liquid line. To understand how car ac refrigerant is used to cool the interior of the vehicle the effects of pressure and temperature should be understood first.

"Automotive Air Conditioning History."
The oil carried by the refrigerant may be the only oil the compressor has to lubricate with.The AC systems used in cars and trucks basically have two types of systems.The first system is called a Thermal Expansion Valve (TXV) system.

(Jan. 25, 2012) http://www.familycar.com/ac1.htmAirconCars.com. The suction line should feel The AC system forms a loop that starts at the compressor. If the pressure of the refrigerant is … An H-Block is a variation of the TXV.The second system is called a Fixed Orifice Tube. Your vehicle’s compressor, powered by the serpentine belt, compresses the refrigerant into a liquid, putting it into a high-pressure state.
I know the gap in the clutch may need to be adjusted but, is the raise in low side pressure normal?Without knowing what the high side pressure is at, I would guess that either the system is overcharged or the cooling fan hub may be bad. The blower pushes air across the evaporator to remove heat from the air. Michael Thomas, automotive and diesel technician, is the author of the McGraw-Hill textbook "Truck and Trailer Systems. There is an accumulator in the line from the evaporator to the compressor.Both systems operate very similarly. This pressure can vary depending on the ambient temperature. Technically a BTU is the amount of heat energy it takes to raise one pound of water (about 1 pint) 1°F at sea level. I have an 03 Avalanche the AC works at an idle but stops once you accelerate. To be able to service and repair an AC system, read through all three articles. New vehicles would be required to use another refrigerant, R134a.
(Feb. 1, 2012) http://www.autoacsystems.com/fasttrack/otubes.htmlEnvironmental Protection Agency. The small Liquid Line should be The Thermal Expansion Valve controls the flow of the refrigerant into the Evaporator. Drier air feels cooler. Using the wrong refrigerant oil could cause serious damage to the compressor.
(Feb. 1, 2012) http://www.aircondition.com/tech/questions/13/All About Auto AC Systems. How Does a Car’s Air Conditioning Work? (Liquids can’t be compressed) The compressor also increases the pressure and temperature of the refrigerant.

Then carried by the discharge line which is typically the smaller line coming from the compressor and should be The condenser is connected to the compressor by the discharge or High (Pressure) Side line. The automotive air conditioning system includes thecompressor, condenser, evaporator, receiver-dehydrator and connecting lineswhich includes expansion valve, orifice tube, suction throttling valve,positive operating absolute valve, evaporator pressure regulator valve, thermal sensor, high pressure cut off switch and cycling compressor switch. The refrigerant leaves the compressor as a gas thru the discharge port.
