Trox Academy introduces new topics

14 January, 2009

Lively discussion was promoted by a new session at the Trox Academy on carbon dioxide as a secondary refrigerant.

The application of carbon dioxide as a secondary refrigerant is now being presented as a topic by the Trox Academy at Thetford. Another recently introduced topic is the calculation of energy savings for VAV fan-coil units using CIBSE-approved software.

The use of CO2 covers the improved efficiency and resilience gained by using high-capacity magnetic hermetic pumps, data-centre cooling using DC motors to improve power factor and overall fan efficiency and changes to the thermal dynamics of blade-server cabinets to increase the removal of heat.

The potential for VAV fan coils to reduce electricity consumption compared with conventional fan-coil systems is another new topic.

Sessions at the Trox Academy are followed by a visit to the laboratory where the actual system is demonstrated and tested, usually in a specially created mock-up area.

More refrigerant bans possible, says government

The government could tighten up the rules that restrict the use of global warming refrigerant gases including speeding up phase-out programmes and introducing new bans, according to a spokesman from the Department for Environment, Food and Rural Affairs (DEFRA).

Baxi research suggests schools strongly support heat decarbonisation

A survey conducted by Baxi of 200 state school estates managers, consultant engineers and M&E contractors has found that while enthusiasm for Net Zero and support for low carbon heating systems in schools is thriving, persistent barriers remain.
