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 two copper lines connect the evaporator section with the condensing unit?
suction line liquid line
What is suction and discharge superheat?
Suction superheat is the heat added to the refrigerant above that required to change its state from liquid to vapour (as happens in the evaporator). This heat is added both in the evaporator, in the suction line and (where applicable) in the suction accumulator.Discharge superheat is suction superheat plus heat of compression, and must be removed in the condenser before condensation, the change of state from vapour to liquid, can occur.The HVAC Veteran
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.
Why is your suction line warm?
your starving the evaporator
What is the liquid line and suction line?
The suction line is the big one. This line should be cold when the unit is on. The small line is the liquid line.
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 two copper lines connect the evaporator section with the condensing unit?
suction line liquid line
Where is the ac condensation line in my Mitsubishi 2000 eclipse?
the vehicle has a liquid line , & a suction line for the a/c . condensation is what happens when you have moisture in the air
How do you quailify for refrigerant recovery epa certification?
A suction line filter is added to the system for a different purpose than the liquid line dryer. A suction line filter is added:A : to keep acidic oil in the system from working its way back into the new compressor.B because the suction makes the acid removal better.C because the suction line is cold and full of acid.D all of the above.
What draws liquid for seduction?
I think you might mean for suction. You use a pipette to draw up liquid with suction.
How much liquid should be allowed in the suction line when charging?
absolutely none. there is almost no more sure way to wreck a compressor than allowing liquid into the compressor.
How is work quench valve in reefer?
A refrigeration circuit is provided with a quench line connecting the liquid line and the suction line and containing a QEV. The QEV is controlled responsive to the superheat of the refrigerant supplied to the compressor. By injecting liquid refrigerant downstream of the suction modulation valve and the sensor for the TXV, the system can be operated at low capacity without overheating the compressor oil.

What are the causes of high suction pressure?
Suction is caused by an are of negative pressure.
What is suction?
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.
How do you tell the suction line in central air conditioning from the high side line?
The suction line will be the larger line going into the compressor.
