What is the effect of air leakage into condenser?
Explanation: Air leakage in the condenser reduces the thermal efficiency of the steam power plant. It increases the amount of cooling water required and also increases the corrosive action in the condenser. The heat transfer rate in the condenser is reduced.
How do you proceed to check the leakage of air into a condenser?
Hence detection of air ingress into the condenser is an important work in power plant. The most common method to identify condenser air in-leakage test is gaseous tracer gas leak test, in which helium or SF6 is used as a tracer gas.
What are the effects of presence of air in the condenser on its performance?
The presence of air lowers the partial pressure of steam and therefore brings down the saturation temperature of steam, which leads to increasing evaporation enthalpy (latent heat), and therefore, more cooling water will be required in the condenser.
What happens when air gets in refrigeration system?
When air enters a refrigeration system, it collects in the top of the condenser and is trapped. Air will cause a reduction in condenser surface area, which will cause a high condensing pressure. Air can enter the refrigeration system through a leak in the low side of the refrigeration system.
What is the purpose of using a condenser?
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
Why is the condenser called the atmospheric?
It basically takes out the latent heat of vaporization; from the gas mixture whether be steam or gas refrigerant to covert it back to liquid. Condenser that works under vacuum such as in boilers are called vacuum condenser; while the others working under normal or low vacuum condition are called atmosphere condenser.
How do you find a leak in a condenser tube?
Identifying condenser tube leak utilizing helium as a tracer gas, coupled with inspection experience, has proven to be the most cost-effective method to date. Plastic, dimple plugs, shaving cream, and smoke have all been used in the past to identify condenser leakage.
What is leakage of condenser?
A condenser coil leak is a serious problem. It’s a very expensive repair that can often result in the full replacement of your unit. A leak in your condenser coil will leak refrigerant, causing your system to have less than the recommended charge (amount) of refrigerant in your system.
What is the partial pressure of air in case of air leakage in condenser exam Veda?
In a steam condenser, the partial pressure of steam and air are 0.06 bar and 0.007 bar respectively.
How do I get air out of my AC compressor?
Turn on the compressor and depress the access valve on the high side. This time, when gas is no longer coming out the high side access valve, let the valve close. The air is now purged from the system.
Why does the condenser use cold water?
If water enters from the bottom of the condenser, it will always be completely filled with cold water which ensures efficient cooling. The condenser cools these vapors condensing them back to liquid droplets that flow down the condenser into the receiver flask.
