What causes Back pressure on cooling system?
Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is: Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer
What causes high head pressure in a compressor?
1.Air Flow 2.Over charged unit 3.Dirty evaporator and condenser coils.4.High amp draw
Does warm air and high pressure causes rising air?
Yes warm air and low pressure can cause rising air.
What is the function of a condensor?
Refrigerant enters the condenser as a high pressure vapor. In the condenser, the heated refrigerant is cooled by transferring its heat to the air which passes through the condenser fins, and it changes state to a liquid during this time.
Air pressure near the equator is less than air pressure at the poles a fact that causes air to move where?
From west to east
What causes high head pressure in an air cooled condenser?
It is due to pressure rising due to a bad condenser fan motor, bad capacitor, obstructing of airflowat the condenser, or a dirty condnser.
What causes high head pressure in a air conditioner?
5 Causes of high head pressure: 1.) Dirty condenser tubes 2.) High temp entering condenser water 3.) Low flow of condenser water 4.) Water bypassing at division plate 5.) Non-condensables in the system
What is the cause a dirty air cooled condenser?
Excessive head pressure.

What should a technician remember about the head pressure of a high-efficiency air conditioning system?
check condenser
A clogged air conditioner condenser would cause what?
high head pressure and a higher supply temp.
What are some causes for air conditioning units to burn out fans?
Dirty condenser coils or condenser air restriction
Is poor compressor can cause high head pressure in an air cooled condenser?
Poor compressor performance should result in low head pressure as the system cools better than the compressor can pump.
What may be used on an air cooled condenser with a fan to prevent the head pressure from becoming too low in mild weather?
water as a coolant
What is definition of high head pressure in a air conditioner?
High head pressure is due to the lack of heat removal during the condensing process of the refrigerant cycle. The outdoor condenser is there to transfer the heat out and condense the refirgerant into a liquid. When ever the condenser is dirty or the fan motor is not working right the result is an increase in temp. and since pressure and temp are directly related the refirgerant pressure is increased thus the term high head
Why the vacuum is maintained in condenser?
For increasing steam turbine efficiency. if vacuum is not maintained then, uncondensable gases and air in condenser will increase the condenser pressure.
