Best Answer

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.

What effects appear if you reduce the diameter of impeller?

Suction head will decrease Delivery head will decrease. Discharge will increase at low suction and delivery head. discharge stagnate at low head than rated head.


High side is the suction or discharge?

Discharge side........


Why is the suction line of a pump larger than the discharge line?

It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.


Where is the water pressure regulator that is controlling head pressure be installed?

On the discharge line with the relief of the pressure control back to suction


What do you mean by head of pump?

Total pump head is the sum of suction and discharge pressure in mtr. ie. 1 bar =10.33 metres of water column


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.


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.


What is a pressure differential?

its pressure between suction and discharge flow...


What does it mean when your suction head is too high and your pump is not pumping water?

suction head is calculated wiht the formula head = 2.31 x psi so if your suction is 30psi then your head is around 60ft. of head. If your suction head is to high then there is not enough water to pump the needed psi for the task
