Abstract

Temperature-controlled transportation of foodstuffs is usually carried out by lorries and trucks having a diesel engine-driven refrigeration unit. It would be desirable to reduce the exhaust gas and noise emissions of the diesel-driven coolers. The objective of the project was to study whether it would be possible to temporarily switch off the diesel-driven refrigeration unit and keep the foodstuffs at the right temperature with the help of a PCM accumulator. A test module was built and the function of it was tested in a test box equipped with a refrigeration unit. Based on the test results, the performance of a full-size lorry was estimated using a numerical simulation model. According to the simulations, a PCM cold accumulator is able to keep the inside temperature of an empty lorry within the desired limits for about 5 hours when the outdoor temperature is +30 oC.
