What will happen if vacuum in surface condenser is very high?

If the vacuum in the surface condenser it very high, it results in higher practical thermal efficiency. It is important for you to keep the temperature to 100 Celsius or lower for it to work properly.


What would the td be for a high efficiency condenser?

The td, or temperature differential, for a high-efficiency condenser typically ranges from 5°F to 10°F (approximately 3°C to 5.5°C). This low temperature differential indicates that the condenser can effectively transfer heat with minimal temperature rise, enhancing overall system efficiency. Maintaining a lower td helps optimize performance and energy consumption, leading to improved reliability and reduced operating costs.


Why the vacuum is maintained in condenser?

For increasing steam turbine efficiency. if vacuum is not maintained then, uncondensable gases and air in condenser will increase the condenser pressure.


What is the condenser approach?

condenser approach is heat transfer the water to gas of condenser efficiency is good less then below (2 F) the system is working good.


How do you calculate the efficiency of air cooled condenser?

You can calculate the efficiency of an air-cooled condenser by dividing the actual heat transfer rate by the maximum possible heat transfer rate. The efficiency is typically expressed as a percentage, with higher percentages indicating better performance. Factors that can affect the efficiency include the design of the condenser, ambient air temperature, and air flow rate.


What does it mean by condenser back prrssure?

Condenser back pressure refers to the pressure at which the refrigerant exits the condenser in a cooling system. It is a critical parameter in determining the efficiency of the system and ensuring that the refrigerant is properly condensed back into a liquid state for optimal performance. A high condenser back pressure can indicate issues with the system, such as poor heat transfer or restrictions in the flow of refrigerant.


What two adjustments can be made to condenser?

Two adjustments that can be made to a condenser are the cooling water flow rate and the condenser pressure. Increasing the cooling water flow rate can enhance heat transfer efficiency, while lowering the condenser pressure can improve the overall efficiency of the system by reducing the boiling point of the refrigerant. These adjustments help optimize the condenser's performance and maintain desired operating conditions.


How often should I clean the fridge condenser coils to ensure optimal performance and energy efficiency?

You should clean the fridge condenser coils every 6 to 12 months to maintain optimal performance and energy efficiency.


How is the efficiency of a refrigeration system affected by the heat rejected by the condenser?

The efficiency of a refrigeration system is affected by the heat rejected by the condenser because the more heat that is rejected, the harder the system has to work to maintain the desired cooling effect. This can lead to decreased efficiency and higher energy consumption.


Does an air condition unit uses a condenser If so is it on the low side or high side?

Yes. The condenser is on the high side, and high pressure vapor goes from the compressor outlet directly to the condenser inlet.
