How does a Heat Exchanger differ from a Calorifier? Can someone clarify?

What is a Calorifier? Are you talking about a heater?

[edit] References

I´ve been doing some search for information in this subject and found a couple of available textbooks on the internet that will surely be usefull for expanding and also refining the concepts of heat transfer.

Please look at:

A Heat Transfer Textbook, John H. Lienhard V, Professor, Massachusetts Institute of Technology.

Lienhard's book is an excellent reference. It covers a broad range of topics and is aimed at undergraduate engineering as well as general use for practicing engineers. Tjcognata (talk) 00:51, 31 March 2008 (UTC)

[edit] chilled beams

Chilled beams are a type of heat exchanger very popular in Europe and gaining acceptance in USA. A major manufacturer is TROX. See website http://www.troxuk.co.uk/uk/products/air_water_systems/chilled_beams/index.php

ASHRAE has started discussion in this area, but I can't find any major articles. A red link to this topic would help to encourage an expert to post information in this area. —The preceding unsigned comment was added by Hank1639 (talk • contribs) 18:12, 8 December 2006 (UTC).

[edit] Properties of Oil

I am building a system which uses oil for the primary heating fluid. My question is: When the oil is heated in an inclosed system, will the oil rise-flow towards the colder fluid not yet heated-without pushing it with a pump? Water will flow on it's own when heated without pumping it, but will oil react the same way? 83.44.57.28 13:48, 26 March 2007 (UTC)

Please see Thermosiphon.

The way these systems operate is via a thermally induced density gradient. Every fluid I am aware of changes density when temperature changes, so you will induce flow in oil by adding or removing heat. You might consult NIST chemistry web-book Thermophysical Properties for fluid specific info.Tjcognata (talk) 01:41, 31 March 2008 (UTC)
