UK: The Institute of Refrigeration has collaborated with CIBSE to produce a new guide to VRF air conditioning.

The authors say that the main purpose of the publication is to provide an independent source of information to assist designers in selecting and configuring VRF systems “to realise their optimum environmental and economic potential”.

VRF systems have grown to dominance in the UK over the last 30 years, with ranges being offered by all the leading manufacturers. “With increased focus on energy efficiency, carbon emissions and sustainability, the need for guidance on the design, application and use of VRF cooling and heating systems has become more important,” say the authors.

The new publication seeks to provide an understanding of the technology, its applications and the differences between VRF and alternative technologies. It also offers information on the calculation of heating and cooling loads and effects on component selection to achieve energy efficient systems. Guidance is given on specification, commissioning and maintenance.

The guide is free to IoR and CIBSE members. £72 inc VAT for non members. It’s downloadable from the IoR website.
