Just recently, Congress enacted a law that mandates all new electronic communication devices must allow government agents free access to monitor the communication. Any attempt to interfere with it or to block government agents from monitoring your communication will put you in jail!
Check temperature on the discharge pipe close to the compressor. Then consult tables of the properties of the refrigerant the compressor works with. If the table shows the condensing (saturated vapor)pressure is the same or close to the pressure you measured, then problem is high consensing...
To explain application of direct solution of the wave equation in the design of mufflers requires solid knowledge of mathematics (partial differential equations, matrix algebra, solution of systems of equations in complex numbers,and programming.
I am sorry for you. You are, or your boss is...
Best source of info is: M.L Munjal,Acoustics of Ducts and Mufflers, John Willey & Sons, 19897.
However, the Four-pole method is an obsolete stuff. A method based on solution of the wave equation is much better.
I will be presenting a paper on this method at this year's 18th International...
There are two ways to balance a rotating machine. The first one is the numerical balancing based on drawings.The second one is in-situ or experimental balancing of a manufactured machine. Which one do you have on your mind?
It seems to me that you may have either not enough refrigerant in the system or system contaminated with air.
A non-working system with correct charge shouldh read (at 70F ambient temperature) 9.38 bar. Under-charged system will read less.
A working system has pressures at evaporator and...
