Air has a pressure, but not a suction pressure. Air pressure is measured with a barometer, you do not calculate it. Suction pressure is a concept which applies to a pump. Suction pressure = static pressure + surface pressure - vapour pressure - friction pressure.
Suction is caused by an are of negative pressure.
for a given air conditioner: the faster the condenser (outdoor) fan the lower the suction pressure. the faster the evaporator (indoor) fan the higher the suction pressure.
On the discharge line with the relief of the pressure control back to suction
Gas Pressure
At very low suction pressure, the suction valves of reciprocating compressor will not work and there will be no gas in the cylinder during compression stroke, resulting some damage to the suction valves. If low suction pressure trip protection is not provided there can be some abnormal damage.

The suction pressure increase.
Answer: The terms suction and discharge are the terms refer to hydraulics. In hydraulics if the the liquid has to be lifted or pumped to the usage area the hydraulic pump will be used . This pump will have to functions that is first suction to lift the fluid and the discharge or delivery . The familiar words in pair are lift and discharge; suction and discharge. The specification of pump for these terms are suction head and discharge head.AnswerThe suction pressure refers to the pressure of the referigerant being "sucked" back into the compressor. The suction pressure is a critical variable in ensuring the accuracy of the refrigerant charge, along with the tepmerature of that line as well. The "superheat", or heat added to the vapor in that line can be monitored in this manner.You have not mention which suction pressure... Actually Where ever the suction is presented that pressure is called suction pressure.... and suction pressure in practical cases normally always less that atmospheric pressure and in case of delivery pressure it is oppositeSaying that suction pressure is " the pressure of the referigerant being "sucked" back into the compressor " is not accurate.Simply , the suction pressure of a pump is the absolute pressure of a fluid , measured at the inlet of the pump ( in your answer , the pump is the compressor , and the fluid is whatever refrigerant. )The discharge pressure , is the absolute pressure of the liquid measured at the outlet of the pump.Obviously, the discharge pressure is usually bigger than suction pressure.
for a given air conditioner: the faster the condenser (outdoor) fan the lower the suction pressure. the faster the evaporator (indoor) fan the higher the suction pressure.
pressure
An A/C compressor sucks refrigerant gas from the evaporator inside the car and compresses it into high pressure liquid. So the tubing that goes from the evaporator inside the car to the compressor is called the suction line.
head pressure
Condensate pump suction pressure below 4 feet of the condenser is almost equal to condenser pressure (760mm of Hg). If the pump equiped under the deep pit , suction pressure is vary.
the head pressure will rise
the head pressure will rise
