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 is the cause a dirty air cooled condenser?

Excessive head pressure.


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 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


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 causes high head pressure in a compressor?

High head pressure in a compressor can be caused by factors such as a dirty condenser coil, restricted airflow, overcharging of refrigerant, or a malfunctioning condenser fan. These issues can result in the compressor having to work harder to maintain proper pressure levels, leading to increased head pressure.


What are the system results of an air cooled condenser operating with a head pressure that ia to low?

Operating an air cooled condenser with a head pressure that is too low can result in inefficient heat transfer, leading to reduced cooling capacity and potentially causing the system to operate with insufficient refrigerant flow. This can lead to lower system performance, decreased energy efficiency, and in severe cases, compressor damage due to liquid refrigerant returning to the compressor.


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 would the head pressure do if the fan motor on an air-cooled condenser stopped working?

The head pressure and compressor current would normally rise (strong winds and/or rain and/or very low air temperatures will reduce this effect). Less heat would be removed from the refrigerant and therefore deliver less cooling.


If the centrifugal pump feeding cooled water to a series of water-cooled condensers breaks down the head pressure of the vapor compression systems will decrease.?

If the centrifugal pump supplying cooled water to the water-cooled condensers fails, the flow of cooling water will be disrupted. This lack of adequate cooling will result in higher condenser temperatures, which in turn decreases the heat exchange efficiency. Consequently, the head pressure in the vapor compression system will decrease, potentially leading to reduced system performance and efficiency. Overall, the system may struggle to maintain optimal operating conditions.


What causes the head gasket to break?

They do fail naturally but the some causes are engine overheating because of water pump failure, pressure problems in the head and water cooled oil coolers splitting and blocking the circulation leading us back to point 1.


What condensers have lower head pressure air cooled or water cooled?

Water-cooled condensers typically have lower head pressure compared to air-cooled condensers. Water-cooled systems are more efficient in transferring heat, resulting in lower operating pressures and temperatures. This can help in reducing energy consumption and improving overall system performance.


What kind of head pressure would you see if the condenser fan became inoperative?

If the condenser fan becomes inoperative, the head pressure in the system would likely increase. This is due to an inefficient heat transfer process, causing the refrigerant to remain at a higher temperature, leading to higher pressure in the condenser. Additionally, the compressor may also overheat and trip the safety controls.
