Where must a suction - line drier be placed in a heat pump after a motor burnout?
Between compressor suction and reversing valve,also called true suction.

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.
Why speed control of DC shunt motor is necessary?
The total voltage of the batteries or DC power source connected to a shunt motor affects how first it moves. Increasing the DC voltage will make the shunt motor run faster.
What is the fan speed relationship to suction pressure?
for a given air conditioner: the faster the condenser (outdoor) fan the lower the suction pressure. the faster the evaporator (indoor) fan the higher the suction pressure.
Why does cooling fan on 1996 mustang gt not work right does not run on high speed when it should?
Fan blower motor?Hi-speed relay badSwitch?Motor winding bad
What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
Where must a suction line be placed in a heat after a motor burnout?
between the comp and the reversing valve
What is the time required from changing star to delta?
The change over time will vary with the type of motor, size of motor and the connected load to the motor. The time should be adjusted so that the motor is up to speed and stabilized at the star speed. It is at this point that the change to delta should take place. One thing to note is, do not leave the motor running is the star position any longer that it needs to.
Which DC motor is constant speed motor?
Dc shunt motor is constant speed motor.Its speed is constant with armature current.This shunt motor is used in paper mills and drilling machines
What position should the output voltage selector be set when using the constant speed motor?
Variable
