    Field measurements and investigation of supermarket refrigeration equipment
    (2019) Konstantinov, I.; Khmelniuk, M.; Yakovleva, O.
    Supermarket owners are looking for commercial refrigeration equipment in order to reduce electricity costs. With advancement in technologies, companies are moving towards introducing smart refrigeration system equipped with sensors. These sensors help in controlling the temperature and also provides temperature monitoring of refrigeration units. Low-power wireless solutions are also being developed, eliminating the cost of inaccurate and manual monitoring of refrigerator units. Persistence Market Research anticipates the global commercial refrigeration equipment to experience a steady growth throughout the forecast period from 2017 to 2026. The global commercial refrigeration equipment market is also projected to be valued at the US$ 45,913.5 million revenues towards the end of the forecast period. This study is based on field measurements which were carried out in "JUKAInvest”LTD laboratory. A number of experiments are carried out over pilot units and the detected temperatures were validated. The research site is developed by specifications, guidelines or characteristics that can be used consistently to ensure that materials, products, processes and services are fit for their purpose in accordance with ISO 23953-2: 2015 (E). Pilot Units are equipped with a modern data monitoring system. All equipment has been certified and complies with international standards. This part of the study investigates the performance of the freezer compartment M400S+. Using the field measurements, low temperature level cooling demands and COPs are calculated for peak loads, filtered and averaged to monthly values. The temperature fields are determined taking into account the features of the unit design, revealing the disadvantages and advantages for tested pilot unit. The obtained study results make it possible to determine the thermal fields for commercial refrigeration equipment, to determine the places of excessive thermal load and the ability to collect the input data to start the creation of a single model for calculating the commercial refrigeration equipment for low temperature units.
