    Development of universal absorption refrigeration devices for operation in a wide range of ambient temperatures
    (2017) Selivanov, A. P.
    In the recent years, greater weight in the structure of agricultural production in Ukraine belongs to individual farms and farmers. In these farms arise the problems of forming a regular economical budget, including a major problem in the preservation of the grown crops for three to six months in commercial quantities and at minimal energy costs. However, the acknowledged fact in world practice is the loss of most of the harvest of agricultural products in the absence of adequate refrigeration storage. Currently, the bulk of Ukrainian harvested fruits and vegetables is traditionally stored in the basements, where during the warm seasons (August—November, April—May) the required temperatures (5…12C) often cannot be maintained. To ensure the required regimes of storage, the market of household and commercial refrigeration equipment for small wholesale manufacturers offers national and imported demountable (panel) cold storages of volumes 3...9 m3, equipped with compression refrigeration machines. In modern conditions in rural Ukraine, operation of such cells is hampered by lengthy power outages and by poor quality electricity incoming (range of fluctuation of voltage is 160—250 V). The current situation makes appeal to heat-powered pumpless absorption refrigeration units (ARU).
