The conduction occurs between bodies of matter, due to a difference of temperature...

...heat spontaneously flows from the warmer body to the colder one.

CONVECTIVE HEAT TRANSFER

The fluid is heated by the contact with the solid boundary...

...the fluid is moved by buoyancy forces due to density differences caused by temperature variations.

Q= S*hc*( Ts- Tf)

The convective heat transfer depends on several factors:- shape and area of the heated surface- surface temperature- fluid temperature

Q= S*hc*( Ts- Tf)

The convective heat transfer depends on several factors:- shape and area of the heated surface- surface temperature- fluid temperature

The conclusion could be that “HEAT RISES”.

This conclusion is incorrect: HOT AIR RISES but HEAT can travel in any direction!

RADIATIVE HEAT TRANSFER

A B A B

Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region

A B A B

Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region

All materials radiate thermal energy in amounts depending on their temperature

The radiation emitted by a body is a direct consequence of thermal state of its matter

the amount of heat transfer from a surface depends on several factors:- type of material- surface area of the heat source- temperature difference between the heat source and the cooler objects

Radiation heat transfer equation takes into account several coefficients:

Q= S*ε *σ * T4

When the temperature of a body increases, the radiative phenomenon is more important than the convective and conductive ones!!

In radiative heat transfer the view factor is very important depending on:- surface areas of the objects- reciprocal distance

The view factor is the proportion of all that radiation which leaves surface A and strikes surface B

CONDUCTION, CONVECTION AND RADIATION

ARE COMPLEX PHENOMENA

AND OCCUR SIMULTANEOUSLY!!

Where can radiant panels be located?

• Ceiling

• Wall• Floor

Radiant panels can be laid on any reasonably large flatsurface and they will heat the surfaces of all the objects

“seen” by the panels.

How are radiant panels heated and how do they work?

A radiant panel has a “skin surface temperature” warmer than the surrounding environment

• radiative heat transfer to the surrounding surfaces

•convective heat transfer to the air

Radiant panels are heated by water pipes embedded in the panels.

Human body exchanges thermal energy with the surrounding environment

Radiant panels allow to obtain this ideal mix of heat exchange forms

Advantages from radiant heating and cooling

✓Homogeneous surface temperature

✓healthy air and no dust circulation

✓controlled humidity

✓wider living spaces with “invisible” installation

Surface heating and cooling guarantees comfort without air movements.

The first use of radiant heating was by ancient Romans who used it in their bathhouses

These buildings were designed with chambers under the floor

...or with small channels within the external walls

The hot exhaust gases were routed through the chambers and through the channels giving their

heat to the surfaces along the way.

The first use of hydronic radiant floor heating using iron pipes was in England around 1907

The first radiant systems:

- were without insulations

- were without intelligent controllers

The first radiant systems:

- were without insulations

- were without intelligent controllers

New standards and new materials have merged the superior comfort aspects of radiant heating with market demands for easy

installation and reliability.

Radiant panels: Just one system for heating and cooling!!

ROSSATO GROUP - INDUSTRIAL FLOOR SYSTEMS

Industrial floor systems INDUfloor and INDUfloor EXTRA

In industrial and manifacturing buildings with high ceilings often occur considerable heat losses....

Dispersioni termiche elevate!

...underfloor heating transfers heat especially to the occupied area and reduces heat losses!

Reduction in energy consumption produces also reduction of costs if compared to a standard air heating system!

Industrial buildings floors performance must be guaranteed with

heavy loads, moving vehicles etc.

Industrial floor performance must be guaranteed in terms of:

- flatness- joint integrity- reduced cracking- resistance to wear

2) The thermal output of the radiant system must be equivalent to the thermal load

3) Evaluation about pipe spacing

4) If the surface heating/cooling is not enough, additional heating surfaces or heaters shall be used

5) In under"oor heating, peripheral areas can be used

6) Lastly is determined the design "ow temperature and the water "ow rates to the single circuits
