Question: How Do You Calculate Condenser Capacity?

How is air cooled condenser capacity calculated?

Actual condenser T.D.can be calculated by dividing the design THR by the 1°F T.D.Condenser T.D.Rating.

Actual condensing temperature can be calculated by adding the actual condenser T.D.to the design ambient temperature.

Actual Condensing Temp.

= Ambient Temperature + Actual T.D..

How do you increase condenser efficiency?

Reducing cooling water temperatures is a sure-fire way to improve condenser performance: A decrease in cooling water temperature of 10 degrees F can improve the overall heat rate of a power plant by 1%.

What are the classification of condenser?

In high level jet condensers, the condensate falls to the hot well by the barometric leg provided in the condenser. Condensers are classified as follows: In jet condensers which is to be condensed. In surface conden the steam which is to be condens In parallel flow the same direction.

What is difference between capacitor and condenser?

Condenser is a term used for a capacitor in the past. … Energy in capacitors is stored in the electric field, while in the case of condensers energy is stored in the electrostatic field (they work as heat capacitors). Condenser can represents a device that converts vaporous material (gas) into its fluid state.

What is condenser capacity?

The condenser capacity is the ability of the condenser to transfer heat from the hot vapour refrigerant to the condensing medium. … The heat transfer capacity of a condenser greatly depends upon the temperature difference between the condensing medium and the vapour refrigerant.

How do I choose a condenser?

Be sure to select condensing units that feed with the same voltage and frequency of the power supply. Also analyze the starting torque. In systems using the expansion valve (instead of capillary tube) you must pay attention if the compressor is in the condensing unit has a high starting torque.

What are the three functions of a condenser?

A condenser’s function is to allow high pressure and temperature refrigerant vapor to condense and eject heat. There are three main types: air-cooled, evaporative, and water-cooled condensers.

Why vacuum is maintained in condenser?

The removal of air and other noncondensable gases from the condenser shell side is required for proper heat transfer from steam to cooling water in the condenser and, thus, to maintain high vacuum in the condenser.

How do you calculate condenser efficiency?

As above indicated the overall efficiency of the 70 condenser being observed under actual working conditions is determined by obtaining the ratio of the value of K for the condenser in operation at a given time, to the value of K for a laboratory perfect condenser operating under identical con75 ditions of water rate …

What is the principle of condenser?

The purpose of the condenser is to receive the high-pressure gas from the compressor and convert this gas to a liquid. It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.

Why fins are not used in condenser?

Because they are so delicate, AC fins whether condenser fins or evaporator fins can bend easily. With normal use air conditioner fins can also get clogged with dirt and debris.

How do you calculate refrigerant capacity?

Divide the quantity of refrigerant that the heat pump moves by the time it takes to move it. If it pumps 3.6 kilograms of refrigerant in 10 seconds: 3.6 / 10 = 0.36 kilograms per second. Divide the answer to step 1 by the answer to step 2: 51.2 / 0.36 = 142.2 kilojoules per kilogram.

How do I lower my condenser pressure?

9.14 Condenser pressure regulators With air-cooled condensers and water-cooling towers it is possible to reduce the air flow by automatic dampers, fan speed control or switching off fans, where two or more are fitted. The control should work from pressure but can be made to work from temperature.

What is the difference between a compressor and a condenser?

The gaseous refrigerant moves to the outdoor unit. Condenser coils in the outdoor unit house the refrigerant during its return to liquid form. The compressor increases pressure on the gas, causing it to condense into liquid. As the refrigerant changes state, it release the heat it contains.
