Coolants are heat transfer media which are intended for use below 0°C. Due to its high specific heat capacity, water is often used even below 0 °C. However, pure water already freezes at 0 °C, i.e. the polar water molecules arrange themselves into ice crystals. Glycol as an additive is an effective solution for this
As a part of the EU, the UK was subject to the terms and conditions of legislation governing the emissions and supply of fluorinated greenhouse gases in Europe. With effect from 1st January 2021 however, these regulations will no longer apply in Great Britain and will be replaced.
In HVAC applications, fans are second only to compressors in consuming power. Here we look at two types of fan motor that have a direct effect on the overall efficiency of a chiller or air handling unit
The energy efficiency of chillers has in the past mainly been indicated by manufacturers by stationary maps at full load operating points or the EER …
Thermosyphon is one method that can be used to achieve free-cooling in a chiller and is discussed in this article
Chillers are used to reject heat from e.g. buildings or industrial processes by means of cooling water. Proper sizing of a chiller is crucial to ensuring that the correct chiller is selected.
