Surface condensers are used exclusively to condense steam in thermal power plants. The coolant used for condensing this steam is generally water.
Amit
the high efficiency is obtained by using a larger condenser surface or by using more mordern alloys with more extended surface or fins
When selecting a 2 ton AC condenser for a residential cooling system, key considerations include the size of the space to be cooled, energy efficiency ratings, compatibility with the existing HVAC system, and the warranty offered by the manufacturer.
In distillation, water evaporates from the condenser due to a difference in temperature between the hot vapor coming from the boiling flask and the cold surface of the condenser. This temperature difference causes the water vapor to condense into liquid form on the condenser surface, resulting in the separation and collection of the distilled water.
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.
More surface area.
Surface condenser is a heat exchanger in which latent heat only absorbed by the cooling media and heat exchange mostly takes place on availble just surface of the tube bundle. Overhead condenses is also a heat exchanger in which latent heat and somewhat sensible heat also removed from the fluid
Ultimate Guide to Selecting Laminate Designs for Every Surface
The fins on the condenser increase the surface area available for heat transfer. This helps to efficiently dissipate heat from the refrigerant as it flows through the condenser coils, allowing it to cool down and change state from a gas to a liquid.
Reasons for low vacuum: 1. Low gland sealing pressure 2. Condenser tubes choked 3. Condenser cooling water temperature high 4. Leakage in condenser tubes 5. Less cooling water flow
More surface area to dissipate heat, the more exposed surface of a material the more place to 'let out' the heat
A condenser is a device which condenses the steam at the exhaust of turbine. Condensers are classified in to two types.Such as (1) Jet condenser (2) Surface condenser It serves important functions. Such as 1. The condenser enables the recovery and recirculation of pure feed water into the plant. Thus, (i)The cost of water softening plant is reduced and (ii) It also saves the cost of fresh water to be supplied to the boiler.
