Whats The Name Of This Compressing Function

If you are referring to an air conditioning compressor, it’s function is to compress the refrigerant used to absorb heat from the cabin air.If the car has an engine with forced induction, the supercharger or turbocharger will have a compressor that pressurises the air used to burn fuel in the engine, allowing more power to be produced. It is quite easy to introduce large amounts of fuel into an engine’s combustion chamber with pressurised fuel injection systems but to make use of the chemical energy stored in that fuel, there also needs to be enough oxygen available to burn it all. The amount of air that can be inducted into the combustion chamber is limited by the vacuum in the cylinder created by the displacement of the piston. Pressurising the air allows a greater quantity (number of molecules) of air to be forced into the engine. More air in the cylinder means that there is more oxygen, which means that more fuel can be burned so more power can be produced.The difference between superchargers and turbochargers is that the supercharger compressor is driven by a pulley mounted on the crankshaft via a belt, whereas a turbocharger compressor is driven by an exhaust gas turbine via a close-coupled shaft. A charge air cooler, often called an intercooler, is often used to remove some of the heat produced during compression of the air, increasing its density (number of molecules in a specific volume), which further increases the amount of air, and therefore oxygen, available for combustion. Here is a schematic diagram of the gas flow through a turbocharged engine with charge air cooling. The air flow into the engine (blue part of the diagram) is similar in a supercharged engine and the charge air cooler may be absent.What the above diagram shows as “Ambient Air inlet” is actually connected to the air filter via a duct, as shown below.

Well though it seems to be a simple question, I would like to make an attempt to talk about compressor very briefly-Compressors are basically those mechanical devices which compress the air to increase its pressure (thus changing its temperature).Most of the time compressors are used as - fans, air blowers, and in most cases used in conjunction with gas turbines (Brayton cycle) etc. And gas turbines are required in power generation, aviation and rocket propulsion.Also compressors as associated with vapor power cycles such Rankine cycle which is usually called as a pump. In Refrigeration cycles and ACs also its used. Both places it compresses air or fluid or vapor isentropically (ideally).The major types of compressors include-1 reciprocating type2 rotary type3 centrifugal type … etcA RECIPROCATING typeSource : Mississippi PowerIts seems to be a simple device but the intricacy in designing a good one is high!So it basically compresses the air or fluid to desired state for further thermodynamic operations.

Nerve compression can better be explained as Cervical Radiculopathy. It is the compression of one or two nerve roots in cervical spine region. Symptoms are pain, weakness, numbness and tingling. It can be managed with the help of Pain Management Doctors. Nerve root injury can occur at any of the five vertebrae in the Lumbar Spine. You definitely want to consult an anesthesiologist in pain management.

The function of a compressor is to increase the pressure, and corresponding saturation temperature (boiling point) of the refrigerant vapor to high enough level so the refrigerant can condense by rejecting its heat through the condenser.Backing up, the vapor compression cycle needs 5 basic components to move heat from inside the refrigerator to the air in your house.  First is the refrigerant, which is the working fluid that moves the heat around.Second is the evaporator.  It is a heat exchanger on the inside of your refrigerator that receives cold, liquid refrigerant.  The refrigerant is on the inside of the heat exchanger and receives heat from the air in the refrigerator.  Since heat goes from hot to cold, the temperature of the refrigerant is approximatly 10F (5C) colder than the desired temperature of the unit.  To make the process more efficient, the refrigerant is near saturation (boiling point) so as the heat is absorbed, the refrigerant evaporates (or boils) from a liquid to a low temperature vapor.Third, the compressor compresses that vapor to a much high pressure.  Since saturation temperature is directly related to pressure and the work of compression is imparted on the vapor, the refrigerant vapor is at a much higher temperature.Fourth, the high temperature vapor enters the condenser at a temperature at 10F (5C) higher than the ambient temperature of the room the refrigerator is in.  This way, air can be passed over the condenser heat exchanger to remove heat from teh refrigerant.  This allows the refrigerant to condense to a high pressure, warm liquid.Fifth, this liquid passes through an expansion device, something that rapidly drops the pressure.  The pressure drop also lowers that saturation temperature down to a point where the refrigerant is ready to enter the evaporator.In other words, the compressor is essential to the refrigeration process.  Without it, you could take bottled gas, expand it through a heat exchanger and abosorb heat but then the refrigerant would need to be vented and you would have to buy more high pressure refrigerant.If you were to try to use a centrifugal pump...pumps are designed for a liquid.  Every try "pumping" vapor with a water pump?  Either nothing happens or it draws such a heavy suction that it essentially works like a centrifugal compressor and motor draw goes up to something higher than if it had been a compressor.

The ear has two main functions. One function is to sense vibrations (sound) in our surroundings and convert them to what we perceive as noises with characteristic such as pitch, frequency, and amplitude/volume. the ear and the brain work together to accomplish this. sound waves are collected in the outer ear and transmit by vibrating on the tympanic membrane. these vibrations are transduced from the tympanic membrane to three tiny bones in the middle ear (malleus, incus, stapes). the vibration of these bones then transmits to the oval window (another membrane separating the middle ear from the inner ear). the vibrations of the oval window continue on to the inner ear in the form of pressure waves in the fluid that fills the inner ear. these pressure waves disturb tiny hairs that line the cochlea. each individual hair that is displaced from fluid compression activates a nerve impulse which then travels from the ear to the brain via the vestibulocochlear nerve. Once this signal reaches the brain, your conscious perceives this as sound.the other function of the ear is to sense acceleration, movement, and position in space.

When you're talking about the limits of compressibility, the exact gases matter.  Air is mostly oxygen and nitrogen.  Other components are minor.The density of liquid nitrogen is .8 g/cm^3; the density of the atmosphere is 1.2 kg/m^3.  The ratio is about 667, so you should be able to pack about that many atmospheres of pressure before it turns liquid.  Liquid oxygen is a bit denser, 1.1 g/cm^3, so it should give you about 900 atmospheres before it turns liquid.  (The actual expansion ratio is actually closer to 860 at room temperature.)
