The proper suction pressure of any air conditioning or refrigeration system is determined by the type of refrigerant used and sometimes the amount of charge. : Suction pressure used is also directly related to the temperature required. : The temperature required in the evaporator relates to the pressure required in the suction line since, the fluid is at saturation in the evaporator. : Knowing the temperature required, use the fluid's saturation tables to find the corresponding pressure required.

HOW TO OPERAte a screw compressor and reciprocating compressors in series?
Your reciprocating compressors have to be the booster compressors (if running on low temp system)feeding its discharge to the suction of the screw(not directly)(if running on medium temp.
Where is suction and discharge s?
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.
Is the suction line the high side?
No, the liquid (discharge) line is the high pressure side. The suction line is the low pressure side.
What is suction power?
A force over an area produced by a pressure difference
How do you maintain net positive suction head of a pump?
first of all the term NPSH should be clear.It is pressure which should be available at the eye of the pump impeller,so as to avoid vaporisation of liquid. Second which arises ,how this liquid will vaporise?Ans-if a vapour pressure of a liquid falls at constt temperature or temperature of liquid is raised at constt pressure it vaporises.In case of pump it's mostly the first case. Now,how to manitain NPSH. NPSHa> NPSHr (always) where NPSHa= available NPSH NPSHr = Required NPSH NPSH = Hps+Hsl-Hvp-Hfl Hps= pressure acting on the eye due to pressure in the suction drum. Hsl = pressure acting due to height of liquid in the suction line. Hvp= vapour pressure of the liquid Hfl= head loss due to friction losses Thus, to maintain the NPSH, variables in hand are,Hps and Hsl.increase the height of the suction line or increase the pressure of the suction drum.
Does low suction pressure have an effect on reciprocating compressors?
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.
How do you determine what suction pressure should be in R410a air conditioning compressor suction line?
Read the charging chart specific to the unit. Not all 410A machines will operate at identical pressures in identical conditions.
What happening when you are overcharging an air conditioning with freon?
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
What is compressor snubber?
Snubber is Pulsation damper that is installed on suction and discharge of compressors. It provides a continuous stream on reciprocating compressors.
How to determine the net positive suction head available?
To determine the net positive suction head available (NPSHA), you need to calculate the total fluid pressure at the pump suction inlet (including atmospheric pressure, fluid pressure, and velocity head), then subtract the vapor pressure of the fluid at the operating temperature and pressure. If the calculated NPSHA is greater than the net positive suction head required (NPSHR) for the pump, it is considered adequate for proper pump operation.

What should be the suction pressure for R22?
The recommended suction pressure for R22 varies depending on the specific operating conditions and equipment. However, typical suction pressures for R22 range from 60-70 psi for air conditioning applications. It's important to consult the manufacturer's guidelines or an HVAC professional for specific recommendations.
What are the causes of high suction pressure?
Common causes of high suction pressure in a refrigeration system can include a dirty or blocked evaporator coil, low airflow due to a dirty filter or a malfunctioning blower motor, overcharge of refrigerant, or a faulty expansion valve. It could also be due to issues with the compressor such as overheating or mechanical failure.
Where is the low port on a 1987 Volvo 240 DL air conditioning system?
The low pressure port (Suction) and the high pressure port (Discharge) are both located on the back side of the compressor.
What is the correct suction pressure for house fridge using R134a?
The correct suction pressure for a house fridge using R134a typically ranges from 5 to 20 psi, depending on factors such as ambient temperature and refrigeration load. It's important to refer to the manufacturer's specifications for your specific fridge model to determine the ideal suction pressure.
Where is the low pressure port for air conditioning on a 1997 Saturn SC2?
The low side port is at the end of the suction hose on the aluminum located where the end bolts up.......
Where is the location of the low pressure suction side on the air conditioning system on a 1992 Toyota Camry?
Right side engine compartment near firewall. hope this helps.
