Summary

The performance of the refrigeration plant is directly affected by the surrounding temperature and humidity. The heatwave in 2022 saw temperatures in some parts of the UK exceed 40°C for the first time. Climate models predict peak temperatures exceeding 40°C regularly in the near future. The integrity of the cold chain rests upon proper functioning of refrigeration equipment. Although forward thinking designers are considering higher ambient temperatures, there is no standard or operating guidelines to steer industry in the right direction. This study carried out surveys and audits to investigate the preparedness of the cold chain to warmer ambient temperatures. Cold stores tend to have older plant (mean of 10.9 years) compared to retail (4.6 years). Condensing temperatures were often higher than optimum, with an example of 40°C recorded when the ambient was only 15°C.
This study recommends a standard method for choosing design ambient temperature, considering location in the UK and life of equipment.
