Summary

This article presents the main results from laboratory measurements on a single vertical cabinet with and without doors. Different opening frequencies of the doors were tested in the laboratory. The results show that the potential for energy saving and improved storage temperature conditions by retrofitting doors to open-front vertical cabinets is quite high. The secondary refrigerant (brine) inlet temperature to the cabinet could be allowed to be higher so that it was possible completely to avoid frost formation in the cabinet air cooler. Using doors as an aid to energy efficiency improvement could also reduce the electricity input for the refrigeration system, and keep food at the correct temperature. This is a key to maximizing shelf life and food quality. The fitting of doors and avoidance of defrosting may also improve the quality of the refrigerated food.
