R-22 systems have the lowest head pressure for residential split systems. As of 1-1-2010, they are no longer being produced. R-22 is being phased out completely.
If you are looking at a new system, the R402a systems are much more "green" and cool very nicely. Blowin Snowballs!

What are the four4 methods for controlling head pressure in an air-cooled condenser?
The four methods for controlling head pressure in an air-cooled condenser include: Variable Speed Fans: Adjusting fan speed can optimize airflow based on temperature demands, helping to maintain desired head pressure. Refrigerant Flow Control: Using expansion valves or solenoid valves to regulate refrigerant flow can help manage pressure levels effectively. Water Spray Systems: Implementing water mist or spray systems can enhance heat exchange by cooling the condenser coil, thereby reducing head pressure. Ambient Temperature Management: Strategically placing the condenser in a location with optimal airflow and temperature can also help maintain efficient operation and control head pressure.
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 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.
What is ferrostatic pressure?
The pressure exerted by the pressure head of liquid steel in a container at bottom surface of the container is known as ferro static pressure.
What is the mean of separation in reciprocating pump?
If the pressure in the cylinder is below the vapour pressure , dissolved gasses will be liberated from the liquid and cavitations will takes place . The continuous flow of liquid will not exit which means separation of liquid takes place. The pressure at which separation takes place is called separation pressure and head corresponding to the separation pressure is called separation pressure head.
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 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
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 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 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 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.
What are the target suction pressure and head pressure?
Target suction pressure and head pressure refer to specific operating parameters in refrigeration and air conditioning systems. The target suction pressure is the desired pressure in the evaporator, typically measured in psi or bar, which ensures efficient heat absorption from the environment. Head pressure, on the other hand, is the pressure in the condenser, necessary for proper refrigerant condensing and is influenced by ambient temperature and system design. Maintaining these pressures within their target ranges is crucial for optimal system performance and energy efficiency.
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 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
