Would the condenser have more or less subcooling if the unit had an overcharge of refrigerant?
An overcharge of refrigerant in the system would typically result in less subcooling in the condenser. This is because the excess refrigerant can lead to higher pressures in the system, causing the refrigerant to be more volatile and reducing the amount of subcooling that occurs in the condenser.
What else can I help you with?
The condensing pressure is 260 psig and the condenser outlet temperature is 108 Degrees Fahrenheit for R-22. By how many degrees is the liquid subcooled in the condenser?
To determine the liquid subcooling in the condenser, you would need the saturation pressure corresponding to the condenser outlet temperature of 108°F. Once you have the saturation pressure, you can compare it to the condensing pressure of 260 psig to calculate the liquid subcooling as the difference between the two pressures.
What would happen if there were more refrigerant in the system than the condenser and receiver could hold?
If there is more refrigerant in the system than the condenser and receiver can hold, the excess refrigerant may cause overloading and damage to the compressor. Additionally, the excess refrigerant may lead to poor cooling performance and reduced efficiency of the system. It is important to ensure that the system is charged with the correct amount of refrigerant for optimal operation.
What would happen if there were more refrigerant in the system than the condenser and the receiver could hold?
If there is more refrigerant in the system than the condenser and receiver can hold, it can lead to poor system performance, higher operating pressures, and potential damage to the components. Overcharging the system can result in decreased efficiency, compressor failure, and safety risks due to high pressure levels. It is essential to have the correct amount of refrigerant in the system to ensure optimal performance and prevent damage.
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.
How subcooling increase the COP of vapour compression refrigeration?
Subcooling increases the efficiency of a vapor compression refrigeration system by ensuring that the refrigerant entering the expansion valve is in the liquid state and at a lower temperature than the saturation temperature, reducing the amount of flash gas that would otherwise form. This results in increased cooling capacity and improved COP (Coefficient of Performance) of the system.
What is meant by degree of subcooling?
The degrees (temperature) from the saturated liquid line. One example would be after refrigerant goes through a condenser. T_subcooling = T_sat - T_condenser
The condensing pressure is 260 psig and the condenser outlet temperature is 108 Degrees Fahrenheit for R-22. By how many degrees is the liquid subcooled in the condenser?

Once you have the saturation pressure, you can compare it to the condensing pressure of 260 psig to calculate the liquid subcooling as the difference between the two pressures.
Why would you run high head and normal suction pressures?
Dirty condenser coil, high ambient temperature, problem with condenser fan, overcharge, non condensibles, high indoor load are the first places I would look. In that order.
What would happen if there were more refrigerant in the system than the condenser and receiver could hold?
If there is more refrigerant in the system than the condenser and receiver can hold, the excess refrigerant may cause overloading and damage to the compressor. Additionally, the excess refrigerant may lead to poor cooling performance and reduced efficiency of the system. It is important to ensure that the system is charged with the correct amount of refrigerant for optimal operation.
Why would outside condenser be making an intermittent roaring noise?
The compressor may have a locked rotor in the condenser causing the loud roaring noise. Another possibility is low refrigerant.
The high side pressure on your auto ac is reading over 400 psi when the ac is on what could be the cause?
A defective fan control, broken fan belt, dirty or blocked condenser coil, incorrect refrigerant, refrigerant overcharge and also the fact that the car is not moving and the hood is open while you are checking it causes the ac system to lose the benefit of the airflow it would normally have by forward movement. 400 psig is way too high.
How would the compressor housing feel when a unit has an overcharge of refrigerant?
A refrigerant compressor will be hot when running whether or not the charge is too high or too low. If the charge is too low, the compressor will cycle on and off. If too high the compressor may not run at all.
What kind of head pressure would you experience if the condenser fan motor became inoperative?
If the condenser fan motor became inoperative, the head pressure in the refrigeration system would increase significantly. This is because the condenser fan motor is responsible for dissipating heat from the refrigerant, and without it, the heat cannot be effectively removed. As a result, the refrigerant would not be able to condense properly, leading to higher pressure in the system. This increase in head pressure can cause damage to the compressor and other components in the system if not addressed promptly.
What would happen if there were more refrigerant in the system than the condenser and the receiver could hold?

What would be the status of refrigerant at discharge line of Compressor?
At the discharge line of a compressor, the refrigerant is typically in a high-pressure, gaseous state. It has been compressed, increasing its temperature and pressure, and is ready to be directed to the condenser. The refrigerant's high energy content at this stage facilitates the heat transfer process as it moves through the refrigeration cycle.
What is the principal of cascade refrigeration system?
To condense refrigerants that are capable of achieving ultra low temperatures that would not be able to condense at room temperature. This is achieved by using a low temperature evaporator of one system as the condenser the other, condensing and subcooling the liquid before entering the metering device.
