Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
Why would your air conditioner have a normal to slightly high suction pressure and low head pressure with a 3 to 5 degree temperature difference?
What you're describing sounds suspiciously like a worn compressor.
What is axial velocity?
Axial velocity is the high pressures created by the pressure built up in a compressor. In a multi stage compressor this is usually very small.
Does refrigerant enter the compressor as a low temperature low pressure gas?
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
What causes an air mass to have a high pressure?
Anti-cyclone
Is poor compressor can cause high head pressure in an air cooled condenser?
Poor compressor performance should result in low head pressure as the system cools better than the compressor can pump.
A refrigerator with a freon restriction would have what symptoms?
High head pressure; low suction pressure; overheated compressor
Why did the air compressor quit turning?
Seized? Low freon charge? High head pressure?
How the compressor working?
Refrigerant enters the compressor inlet as a low pressure vapor. The compressor increases the pressure, and discharges it as a high pressure vapor.
What is suction and discharge head?
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
Why should you never front seat the discharge service valve while a compressor is running?
This will cause the head pressure to climb very high and if something doesn't explode or cut out on a high pressure safety, you and the equipment will be damaged. Hopefully compressor will be one with internal or external overload. To summarize DONT DO IT WHILE COMPRESSOR IS RUNNING.
Where is the high compressor air condition hose?
The high pressure hose is between the compressor and orfice tube
Does refrigerant exit the compressor as a high temperature high pressure liquid?
No , a high temperature high pressure ( gas )
What is intermediate pressure turbine?
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.

Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
What happens if a r404a compressor runs with nitrogen in itinstead of refrigerant?
your head pressure will rise through the roof maybe pushing 800+psi on the high side, and will most likely burn out the compressor in a matter of seconds
