MODEL: HE 104

of heat transfer as applied to a liquid-to-liquid heat exchanger. A simple arrangement of valves allows

DESCRIPTION

The apparatus requires only a cold water supply, single

phase electrical outlet and a bench top to enable a series

of simple measurements to be made by students

needing an introduction to heat exchanger design and

operation. Experiments can be readily conducted in a

short period of time, without the need of setting up

operations, to accurately show the practical importance

of the followings:

a) Temperature profiles

b) Co- and counter-current flow

c) Energy balances

d) Log mean temperature difference

e) Heat transfer coefficients

The equipment consists of a concentric tube exchanger

in the form of “U”, mounted on a support frame. The

external surface of the exchanger is insulated. Six

temperature sensors are installed in both the inlet and

outlet tubes, to measure the fluid temperatures

accurately. To minimise losses in the system, the hot

water is fed through the inner pipe, with the cooling water

in the outer annulus. Control valves are

balances, heat transfer coefficients and log mean temperature differences to be obtained for both conditions.

incorporated in each of the two streams to regulate the

flow. The flow rates are measured using independent

flow meters installed in each line.

Temperature and flow readings could continuously being

captured and logged into the computer with optional

Data Acquisition System. These data are useful for

further calcula­tions and analysis. On-line trending

display allows student to observe the fluctuations of flow

and temperature readings immedi­ately.

The hot water system is totally self-contained. A hot

water storage tank is equipped with an immersion type

heater and a temperature controller. Circulation to the

heat ex­changer is provided by a pump, and water

returns to the storage tank via a baffle arrangement to

ensure adequate mixing. The cold water required for

the exchanger is taken from the laboratory mains supply.

A readily identifiable valve arrangement allows simple

change-over between co- and counter-current

configurations.

EXPERIMENTAL CAPABILITIES

♦ Energy balance determination

♦ Temperature profiles in co- and counter-current

flows

♦ Log mean temperature difference

♦ Heat transfer coefficient calculation

♦ Effect of flow rate on heat transfer rate

♦ Heat loss estimation and ‘k-factors’

SPECIFICATIONS

Bench mounted concentric tube arrangement in ‘U’

shape, whereby heat transfer takes place between hot

and cold water streams. External surface of the

exchanger is insulated. Six temperature sensors and

two rotameters are located in each of hot and cold lines.

Flow regulators are incorporated in both streams.

Simple valve arrangement allows change-over between

co- and counter-current configurations. Requires only

cold water and electricity.
