Comparration diameter size of suction and discharge?

The diameter of the discharge line leaving the ac compressor would be smaller than the suction line, because the compressed gas in the discharge line is more dense.


Should the suction line be cold?

On split system installations, the suction line should be pitched towards the compressor at least Suction line should be insulated for 2 reasons: 1) so it does not drip condensation everywhere it passes through the homes interior space. ie attic, inside walls etc. 2) cool suction gas is what cools the compressor motor during operation, insulating the pipe carrying it helps prevent that gas from picking up heat from the surrounding air ensuring it remains an effective coolant for the motor. The original reply was also correct, an effort to pitch the suction line towards the compressor should be madr wherever possible to aid in oil return.


How is the capacity of a screw compressor controlled?

Capacity control is the process by which the flow of the discharged gas from the compressor is controlled. This can be accomplished by several method. 1. Controlling the speed of the compressor. 2. Controlling the clearance of the compressor. 3. Throttling the suction valve. 4. Suction valve unloader.


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?

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.
