The combination of the knowledge of refrigeration systems, legislation and CRT’s test facilities has given us a strong understanding of the issues surrounding mobile and stationary refrigeration and air-conditioning systems.

The Montreal protocol has been successful in enforcing the phase out of ozone layer damaging CFC’s and also the phasing out of HCFC in new equipment and insulation material. Although the chlorine free HFC refrigerants are non ozone layer depleting, many have a high GWP (Global Warming Potential). Refrigerants such as HFC-134a, HFC-404a, HFC407C, and HFC410a are well established and there is no date set for phasing-out other than in vehicle (mobile) air-conditioning. However, new legislation such as the “F” gas directives from the EU are aimed at regulating their use due to their GWP.

Advances in refrigeration will rely on the use of natural refrigerants (ammonia, air and carbon dioxide) and new refrigerants with low GWP and a high energy efficiency.

CRT can act as consultants in the following areas:

• Chilling, freezing and thawing
• Reductions in refrigerant leakage
• Fault analysis
• Energy efficiency and COP predictions
• Trouble-shooting existing systems
• Temperature control and control systems during, processing, storage, transport and finally retail display
• Condensation issues
• Water chillers
• Advice on the alternative refrigerants
• “F” gas and Stek regulations
• Refrigerant phase out dates
• Plant & cold store evaluation
• Equipment conversion in refrigeration and a/c plant
• Refrigeration plant failures
• Enhanced capital allowances (ECA’s)
• Replacement refrigerant physical characteristics
• Advice on ODP,MAC,TEWI,GDP,LCCP
