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!

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 is the maximum suction head for pumping water?
I think, that's refer from your system. If you manipulate the surface pressure of the water, you will get a big value of water suction head with higher surface pressure. CMIIW....
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 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 kind of head pressure would you see if the condenser fan became inoperative?
Very high
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 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
Four methods for controlling head pressure in an aircooled condenser are?
fan cycling.3 way modulating valve
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
How can I get higher water pressure in my shower faucets?
The simplest and lowest cost solution is to replace the shower head with one designed to increase the pressure.
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.
