Climate Change in Moldova by late XXI century will manifest by the ambient temperature rises to 5.6 K and reduced water availability up to 55 %, which, on the one hand, will reduce energy consumption for heating up to 60 % on the other, will increase ventilation and conditioning consumption by over 120 %.. Water scarcity will impose strict economy of water and identifying new water sources. It is reasonable to accumulate condensed water from fruit drying installations and its subsequent use. This process is possible to achieve in the drying device, which consists of a heat pump and solar collector.
