The MP39 refrigerant, also known as R-401A, typically operates with suction pressures ranging from about 25 to 40 psi and discharge pressures between 150 to 250 psi, depending on the specific application and system conditions. However, these values can vary based on factors such as the evaporator and condenser temperatures. Always consult the manufacturer's guidelines and charts for accurate pressure readings specific to your system.
What else can I help you with?
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 would happen if the suction service valve is backseated and the discharge valve is front seated with the system operating?
If the suction service valve is backseated while the discharge valve is front seated during operation, it would effectively prevent any flow of refrigerant into the compressor, potentially leading to a loss of lubrication and overheating. This situation could cause the compressor to operate under low suction pressure conditions, risking damage or failure. Additionally, backseating the suction valve might create a vacuum that could pull in air or contaminants, further compromising the system's integrity. It's crucial to maintain proper valve positions to ensure safe and efficient operation.
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
Why would a suction line ice up?
Its due to the refrigerant dropping to a temperature that's below freezing(32 degrees at sea level) and the humidity(water) that forms on the suction line freezes caused by several things: shortage of freon, dirty evaporator coil, oversized unit, and dirty filter.
If you have well water would a crack in the PVC pipes cause air in the pipes?
Any break or leak on the suction side of your pump can cause air in the lines.
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.
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.
How would you prove a bad suction reed in a compressor?
To prove a bad suction reed in a compressor, you would need to do a pressure test. You can isolate the compressor and check for pressure drop in the suction line. A significant pressure drop would indicate a faulty suction reed. Additionally, you can inspect the reed valve for visible signs of damage or wear.
Would a suction cup work in a vacuum?
Yes, a suction cup would not work in a vacuum because there is no air pressure to create the necessary force for the suction cup to adhere to a surface. Without air pressure to push against, the suction cup cannot create the vacuum required to stay attached.
A refrigerator with a freon restriction would have what symptoms?
High head pressure; low suction pressure; overheated compressor
Is installation of pressure gauge mandatory after a centrifugal pump?
It is certainly not mandatory unless the system it is designed around calls for them, but they certainly are handy and a welcomed if you ever have to troubleshoot the system. I never design a pumping system without having suction and discharge gauges. Of course, on a submersible pump, you would only have a discharge gauge.
What is the SI unit for suction?
I guess that would be measured in units of pressure: Pascal = Newton/meter2.

What symptoms would be indicative of an oil logged condenser?
High discharge pressure and low liquid line pressure
What should the low pressure be on a hvac system?
The pressure should be equal to a saturated suction temperature of around 40*F. The pressure would differ depending on which refrigerant is used.
Which port on AC compressor is low pressure 1999 Chevy blazer?
They may be marked "S" and "D" for suction (low side) and discharge (high side). A simpler way would be to look at the lines going into and out of the AC.... the smaller line will be the high pressure line, while the larger line will be the low pressure line. The low pressure line will connect at the compressor inlet, and the high pressure line will connect at the compressor outlet.
Why suction of blower is up side and discharge lower side?
If you are asking why the low side is high and the high side is low that would indicate that you have a restriction in the a/c system...........
