What is the efficiency of condenser?

The thermal efficiency of a condenser is defined as the ratio of actual rise in temperature of cooling water to the maximum possible rise. ts = saturation temp., corresponding to condenser pressure (i.e., vacuum temp.) Numerical Example : Vacuum in a condenser is found to be 708.5 mm Hg .

How do I increase my condenser vacuum?

10 Tips to Ensure Reliable Vacuum Condenser Performance

1. TIP 1: Conservatively Estimate Noncondensible Loading.
2. TIP 2: Understand Vapor-Liquid Equilibrium of the Vapor Components in Your Process.
3. TIP 3: Properly Elevate a Vapor Condenser.
4. TIP 4: Define the Range of Cooling Water Temperature and Flow Rate.

Which parameters do affect the condenser performance?

The parameters that are responsible for condenser thermal performance are cooling water (CW) mass flow rate, temperature, heat transfer area, velocity, tube fouling, partially filled water box and air leakage. CW flow rate and condenser pressure changes according to the variation in unit load.

What will reduce condenser capacity?

A major reduction in capacity is normally related to the evaporator performance. Problems with the condenser are usually manifested as an increased pressure head.

How do I know my condenser capacity?

– The formula for the capacity of condenser is given by C=Ad When A is the area of each plate and d is the distance between the plates.

What are the methods to increase the efficiency of Rankine cycle and explain any one?

Increasing the Efficiency of Rankine Cycle That is, to increase the efficiency one should increase the average temperature at which heat is transferred to the working fluid in the boiler, and/or decrease the average temperature at which heat is rejected from the working fluid in the condenser.

What causes vacuum in condenser?

Water is used to condense steam back to liquid water in any form of boiler system, whether on board ship or in power plants. A vacuum is maintained in the condenser so that steam can easily flow and more work can be extracted from the steam in the turbine; this is the reason why vacuum is maintained in condensers.

How much heat must a condenser dissipate?

Air cooled condensers normally requires between 125°F to 130°F condensing temperature to reject heat to a 100° ambient, while a water cooled condenser can operate at 105°F condensing temperature and reject its heat to a 95°F water stream.

What is the heat load on the condenser?

Condenser heat load is the amount of heat that must be removed from the inlet stream to attain the specified removal efficiency.

Which type of condenser is the most efficient?

Water-Cooled These shell-within-tube condensers are very efficient. Water-cooled condensers are more complex than air-cooled condensers as there are design considerations in water flow regulation and corrosion prevention.

How can I increase the seer of my condenser to 16?

This is most often done by matching the condenser with a variable speed furnace and a horizontal slab coil (often a third party). The result of this added equipment is a more efficient system overall. Reaching 16 SEER in this context is based on all variables working together.

How does vacuum affect condensation efficiency?

One metric of this condensation efficiency is the condenser pressure, often measured as vacuum. A condenser that can pull a stronger vacuum not only results in a higher cycle efficiency but also more potential power output.

What are the advantages of a condenser system?

Electrical Efficiency. Condenser systems need either circulating water pumps to supply them with cooling water or fans to supply fresh air to air-cooled tubes. (Because most air-cooled condensers are relatively new devices, they tend to already have fairly modern motors and controls; thus, the potential for savings is less.)

How can I reduce the pressure in my air conditioner?

Using plastic or metal brushes to clean the tubes can yield a benefit of approximately 0.1 inches Hg in vacuum, while a more involved mechanical cleaning can reduce condenser pressure by 0.6 inches Hg or more.
