What is the purpose for subcooling the liquid refrigerant before it leaves the condenser?

So the refrigerant won't go into sensible heat and reject the process because no vapor is left to condense. This causes the liquid to drop below the wondering saturation temperature of 125°.

AC sub cooling reading?
How do you measure Sub-Cooling for a R-22 AC system SUB-COOLING IS THE THE "HEAT BELOW SATURATION". THE SUB-COOLING LEAVING THE CONDENSER IS CALCULATED BY TAKING THE (ACTUAL)CONDENSING TEMPERATURE AND THEN SUBTRACTING (MINUS)THE LIQUID REFRIGERANT TEMPERATURE (USE THE CHART)LEAVING THE CONDENSER.=THE SUBCOOLING. NORMAL SUBCOOLING AT THE CONDENSER OUTLET SHOULD BE 10*F. THIS WILL ENSURE THAT LIQUID WILL NOT FLASH INTO VAPOR BEFORE IT GETS TO THE EXPANSION VALVE, SHOULD THERE BE A SLIGHT INCREASE IN TEMPERATURE OR A SLIGHT DECREASE IN PRESSURE DUE TO A PRESSURE DROP. SUB COOLING INCREASES CAPACITY & PREVENTS FLASH GAS IN THE LIQUID LINE AHEAD OF THE EXPANSION VALVE. I HOPE THIS IS VERY CLEAR, AND HELPS U FIGURE OUT HOW TO MEASURE IT. TODD S.

Why are you using condenser in rankine cycle?
The condenser is used to lower the temperature of the working fluid. This lowers the pressure and condensates any left over steam, from the turbine, so it will be purely liquid before entering the pump.
How does a condenser convert gas into liquid?
steam from the turbine passes through tubes that are suurounded by water that is cooler than the steam the steam is therefore cooled the steam then turns back into water condensation =condensor
What is another term for suction pressure?
Inches of vacuum. Thirty inches of vacuum is generally considered a complete vacuum when evacuating a system before purging it with nitrogen gas to completely dry the system out before recharging it with whatever refrigerant is to be used. This assumes that what ever problem generated the need for the system to evacuated has been resolved.
Purpose of adding NaOH to the mixture before taking the polarimeter reading?
To neutralize the solution and to prevent the complete hydrolysis of sucrose into glucose and fructose.
Why is subcooling desirable?
It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor must run to maintain the temperature. The amount of capacity boost which you get with each degree of subcooling varies with the refrigerant being used. Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before it reaches the evaporator. Inadequate subcooling prevents the expansion valve from properly metering liquid refrigerant into the evaporator, resulting in poor system performance.
What happens with refrigerant in the condenser?
The refrigerant which was in the form of gas before entering the condenser, condenses (converts to liquid refrigerant) as a result of the gas being compressed. This condensation will release heat which is partly taken away by the function of the fan (the rotating blades) in order to prevent the compressor from overheating.

What is the purpose of air con refrigerant definition?
Refrigerant is the material that absorbs heat when evaporating and releases heat when condensing. If not for refrigerant in the system, it would not function. Before refrigerant, other more dangerous gases were used to achieve the same goal, such as propane.
What is the function of condenser?
Answer:collect and concentrate the light ( focus the light into cone) Answer:In air conditioning systems, the condenser coil is where the heated refrigerant gas is cooled to a liquid state (usually outdoors) before being cycled back to the evaporator coil inside the vehicle/building where it can absorb more heat to be carried back outside to the condenser coil in a repeating cycle. Answer:The condenser receives hot high pressure gas refrigerant from the air conditioning compressor. It cools this gas (it looks like a radiator) turning the gas into a cooler liquid. (condensing it)
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.
What is the function of compressor in refrigerator?
A refrigerator compressor is the center of the refrigeration cycle. It works as a pump to control the circulation of the refrigerant, and it adds pressure to the refrigerant, heating it up. The compressor also draws vapor away from the evaporator to maintain a lower pressure and lower temperature before sending it to the condenser.
What is the purpose of the coiles under a refrigerator?
The purpose of the coils under a refrigerator are to allow the refrigerant to cool down before being turned back into a liquid. This allows the compressor to function properly.

Why is refrigerant vapor re introduced to the refrigeration system before refrigerant liquid?
To endure that the ONLY gas in the system is refrigerant.
What is the purpose of a condenser in distillation?
I have been rebuilding a 4 stroke Tecumseh engine and I was wandering just what does a condenser do in the ignition system? The condenser stores the charge that the magneto makes until it is time for the spark plug to fire. The points control how long the magneto charges the coil and they also give the signal to the fire the plug.
