# How do you calculate lmtd in heat exchanger?

## How do you calculate lmtd in heat exchanger?

by definition given above, LMTD for counter current flow = (60-50) / ln(60/50) = 10 / 0.1823 = 54.850C. For co-current heat exchanger, ΔT1 = TH1 – TC1 = 100 – 30 = 700C (At first end hot and cold fluids enter the heat exchanger.)

## What are the parts of a heat exchanger?

The Major Components of Heat Exchangers

• The Tubes. Tubes are perhaps the most important component of a heat exchanger.
• Front and Rear Headers. The front and rear headers of heat exchangers are where the liquid enters and leaves the tubes.
• Transfer Line Exchangers.
• The Air Cooling System.
• Why Heat Exchange Is Necessary.

## What is the function of a heat exchanger?

Heat exchangers are integral parts of fuel cell systems for thermal management functions related to heating of incoming gas streams, exchange of heat from various flow streams and maintenance of the uniformity of temperature.

## Is condenser a heat exchanger?

A condenser can be considered a form of heat exchanger as it is similar to a chiller heat exchanger in function./span>

## What are the types of evaporator?

TYPES OF EVAPORATOR

• Natural/forced circulation evaporator.
• Falling film evaporator.
• Rising film (Long Tube Vertical) evaporator.
• Climbing and falling-film plate evaporator.
• Multiple-effect evaporators.
• Agitated thin film evaporators.

## What is the function of evaporator in chiller?

The evaporator functions as a heat exchanger such that heat captured by the process coolant flow transfers to the refrigerant. As the heat-transfer takes place, the refrigerant evaporates, changing from a low-pressure liquid into vapor, while the temperature of the process coolant reduces./span>

## What is chiller components?

chiller components parts of a chiller. The main chiller components are the Compressor, Condenser, Evaporator, Expansion Valve, Power Panel, Controls unit and the Water Box./span>

## What is the working principle of chiller?

A chiller works on the principle of vapor compression or vapor absorption. Chillers provide a continuous flow of coolant to the cold side of a process water system at a desired temperature of about 50°F (10°C)./span>

## What is chiller unit?

Typically in heating, ventilation and air conditioning systems, chiller units produce chilled water that is piped to air handling units (or fan coil units) where it is used to cool the air that ventilates the building. The ‘warmed’ water is then returned to the chiller unit to be re-cooled./span>

## What is chiller and types?

Types of Industrial Chillers There are three different types of chillers:(1) air, (2) water, and (3) evaporative condensed chiller. There are four subcategories in each of the above categories for industrial chillers: (1) reciprocating, (2) centrifugal, (3) screw driven (4) and absorption chillers.

## Where is chiller used?

Normally the chiller cools the cold water storage, which, in turn, provides the space cooling to the building. The chiller can be directly connected to the building in the case that the temperature of the cold storage is too high to cool the building, but the chiller can operate with heat from the hot storage.

## Which gas is used in chiller?

Chillers used to cool industrial processes are included under the category of “industrial process refrigeration”. Accepted refrigerants for this application are: R-410A, R-404A, R-407C and R-134a are accepted on all chillers, except for those with scroll compressors./span>
