The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line.

What is the most common cause of high head pressure?
Bad Fan Motor This is actually the most common issue that causes high head pressure. You can have a bad fan motor due to a few different reasons. Your fan blades naturally wear down over time. The process of them wearing down can be expedited by debris finding its way into your air conditioner's outside unit.
Can restricted TXV cause high head pressure?
Some of these, such as a bad TXV or clogs in the refrigeration system are cited as the most common causes of high compressor head pressure.
High Suction Pressure Resolved
What causes high head pressure and high suction pressure?
Overcharging of refrigerant, liquid slugging of the compressor, oil contamination and other sources can damage compressor valves. Refrigerant overcharging will show up as high head pressure, normal suction line pressure, normal superheat, high sub-cooling.
What causes high head pressure?
The high head pressure is caused in most of the cooling systems. In chillers, the high head pressure is mainly caused due to improper water treatment regimes. The clogging of the coils can cause high head pressure in the chiller. The condenser water loop is open to the atmosphere in the chiller.
What causes high head pressure in a chiller?
The high head pressure is caused in most of the cooling systems. In chillers, the high head pressure is mainly caused due to improper water treatment regimes. The clogging of the coils can cause high head pressure in the chiller. The condenser water loop is open to the atmosphere in the chiller.
Do Line Restrictions Cause High Head?
What are two causes for high head pressure readings on a system?
- Dirty Condenser Coils. Your coils in your air conditioning system can become dirty over time. ... - Bad Fan Motor. You might notice that you have high head pressure if you have a bad fan motor. ... - Refrigerant Issues. ... - Non-Condensing Gases.
What causes high discharge pressure on a chiller?
One common cause of high discharge pressure is the cooling medium (air or water) flowing across the condenser: either there is not enough or the temperature of the cooling medium is too high. This is normally easy to identify with a simple visual inspection of the condenser.
High Return Air Temperature Effect On Suction Pressure On The Air Conditioner
What is high discharge pressure in refrigeration?
High discharge pressure can be defined as the pressure of the gas compressor's which carrying by the suction line into the air conditioning system is facing leakage from the discharge valve is present in the compressor's output side and combined with an indicator's lower suction pressure. High Discharge Pressure.
What are the causes of high head pressure?
- Overcharging of the refrigerant in the system. - Operating the system at high range than the specified limit. - Malfunctioning of the condenser fan motor. - The system is charged with the impurities of non condensing gases. - The condenser coil is not cleaned well. - Refrigeration device plugged.
